Design of valve unit

The steering valve consists of a steering hydraulics proportioning pump

(229) and an Orbitrol rotary valve (609).

The Orbitrol rotary valve (609) is actuated by the steering gear shaft. Continued rotary movement of the steering gear shaft drive the steering hydraulics proportioning pump (229) by means of a socket-type shaft.

Neutral

2-8 DO-h-Kap2 04/04

TIC Dominator 140 - 150 Hydraulic System

Description of function:

Neutral In neutral position, the oil is directed back to the tank via the steering

safety valve (742) and the Orbitrol rotary disc (609) (open center). The circulation pressure must not exceed 20 bar. Both sides of the steering hydraulic cylinder (323) are shut off by the Orbitrol rotary disc (609). Pressure peaks due to external forces on the steered axle are relieved to the tank via the steering double shock valves (725) (non reaction).

Hydraulic System Dominator 140 - 150 TIC

Steering actuation

2-10 DO-h-Kap2 04/04

TIC Dominator 140 - 150 Hydraulic System

Description of function:

Steering actuation When actuating the steering to one or another direction, the Orbitrol rotary

disc (609) is rotated by up to 8° relative to the outside spool. During this process, the return line from the steering hydraulics pump (218) to the tank is closed and the connection to the steering hydraulics proportioning pump (229) is released.

Via the steering hydraulics proportioning pump (229) and the Orbitrol rotary disc (609), the volume flow is released as a function of the sense of rotation, path and speed of steering wheel motion to the ram or the ram ring surface of the steering hydraulic cylinder (323). Here, the displacing surface of the steering hydraulic cylinder (323) is connected with the return line to the tank via the Orbitrol rotary disc (609).

As soon as there is no more steering motion, leaf springs bring the outer rotary disc of the Orbitrol rotary disc (609) back to neutral position. Now both sides of the steering cylinder are shut off again and the connection from the steering hydraulics pump (218) to the tank is re-established.

Emergency steering When the steering system is not supplied any more by the steering

hydraulics pump (218), the steering safety valve (742) closes and thus ensures that no oil will escape from the steering system.

When the steering is actuated, the inner and outer disc of the Orbitrol rotary disc (609) are rotated relative to each other. Now the oil can be conveyed from one side of the steering hydraulic cylinder (323) via anticavitation valve (non-return valve) (728) to the other side through human power by the drive of the steering hydraulics proportioning pump (229).

Hydraulic System Dominator 140 - 150 TIC

2.4 Checking the steering

Steering gear shaft Height play = 0.1 to 0.3 mm

Clearance from bottom inside rotary disc = 3 mm

Return When the steering wheel is actuated with the diesel engine shut off, the

leaf springs in the rotary disc must bring the steering wheel back to its neutral position.

Reaction If steering reaction is insufficient, internal leaks in the steering system

must be checked. To do this, disconnect the lines from the steering cylinder and plug them tightly with plugs. With the oil at operating temperature and at max. no-load speed of the diesel engine, the steering wheel must not allow more than 4 turns/minute in both directions when using a force of approx. 25 Nm. When the actual number of turns is more than 4/minute, check the steering valve for leaks. When the actual number of turns is below 4/minute, check the steering cylinder for leaks.

Power In case of steering forces above 25 Nm, check tyre size and pressure,

condition of the cylinder rod and if stub axles move smoothly. A pressure test at the steering hydraulics measuring port must show the value 90

bar. To this end move the steering wheel up to the stop and hold it in this position. Adjusting the pressure relief valve on the machine in built-in condition is not possible.

Important! Any installation work on the steering hydraulics must be

followed by venting the system on both hydraulic lines of the steering cylinder with the diesel engine running.

Hydraulic System Dominator 140 - 150 TIC

Basic setting

To ensure the position of spool (H) for the function "Raise front

attachment", the dimension from the top edge of the spool (H) to the body must be 4.3 mm with the coil core (Y85) removed. The position may be corrected by removing or adding shims above the compression spring.

A weaker compressed spring - as compared to the spool (H) - is located

below the spool of the master valve (U).

In order to guarantee the "Front attachment lower" function, the clearance

between the top edge of spool (L) and the housing must be 4.5 mm with the coil core (Y87) removed. The position may be corrected by removing or adding shims.

Spare part no: 0.1 mm = 0218 886.0

04/04 DO-h-Kap3 3-9

Hydraulic System Dominator 140 - 150 TIC

Description of function:

Function of master valve The master valve (Y77) blocks the circulating volume flow from P to T of

the open hydraulic system when a working hydraulics function has been actuated. Single-acting functions are an exception to this if the consumer is relieved to the tank.

In neutral position, the master valve (Y77) is not actuated, making the oil

flow back to the tank via the ring channels on the spool (U). Due to the large channel cross-section, the circulation pressure is very low.

When pressure is successfully built up at a consumer, the master valve

(Y77) is actuated simultaneously with the directional control valve of the corresponding function. Now spool (U) closes the connection from P to T, and the top ring channel being closed first in order to achieve smooth switching-over.

The pressure relief valve (703) opens at a maximum system pressure of

180±10 bar and relieves the pressure to the tank.

Raise front attachment function

Raising When the "Raise" function is used, the directional control valve (Y85) and

the master valve (Y77) are actuated with 12 V DC.

The spool (H) is moved to its end position, making oil flow via both ring

channels on the spool (H). The full volume flow is directed to the consumer port (A1) via the non-return valve (732) and raises the front attachment.

Lower front attachment function

Lowering When the "Lower" function is used, only the directional control valve (Y87)

is actuated with 12 V DC.

The spherical seat in pilot valve (V) is opened and the spring force (F) is

overcome through the force of the solenoid. The spool (E) closes the ring channel to the return line, making the load pressure of the front attachment act on the ram top side (K) and open the pilot valve (743). The oil is now displaced by the front attachment via the pilot valve (743) and the control spool (R) into the return line to the tank.

3-10 DO-h-Kap3 04/04

TIC Dominator 140 - 150 Hydraulic System

Description of function:

Flow control valve When the "Lower front attachment – fast" function is used, the oil

displaced via port A flows to the tank (T) through the restrictor in the control spool of the flow control valve (614).

This creates a ram pressure ahead of the control spool, making the latter

move against the control spring and restrict the return channel to the tank (T) as a function of the load pressure.

When the load pressure in port A changes, both the volume flow through

the restrictor and the load pressure against the control spool change, too, and consequently also the return channel cross-section.

This control function keeps the volume flow and therefore the front

attachment drop rate constant, independent of the load pressure.

The front attachment drop rate is adjusted merely by the pre-stress of the

control spring at the handwheel.

Relieve tension of control spring = lower drop rate Tensioning the control spring = increase drop rate

TIC Dominator 140 - 150 Hydraulic System

Description of function:

Oil supply After starting the diesel engine, the ground drive feed pump (209) is

driven. In this process, the oil quantity is taken from the housing. The housing is directly connected with the oil tank (110).

Feed pressure circuit The feed pressure builds up from the oil quantity pumped through the oil

cooler (109) and the pressure filter (102) by the ground drive feed pump (209) against the ground drive feed pressure relief valve (716). Depending on the spring setting, the oil flow is pre-stressed and then relieved to the tank.

The feed pressure is applied at the combined ground drive multi-function valves (713/714) and at both servo cylinders via the ground drive servo adjustment valve (606). When the ground drive variable displacement pump (211) is not swung out, the feed pressure propagates to both sides of the high-pressure circuit via ground drive multi-function valves (713/714).

Servo control The cable mounted on the ground speed control lever moves the spool in

the ground drive servo adjustment valve (606) from the neutral position to one or the other direction. Depending on the direction of travel, one of the ground drive pump servo adjustment hydraulic cylinders (313) is pressure-relieved whereas the other hydraulic cylinder remains connected to the feed pressure circuit. The motion at the swing disc corresponds to the pressure difference between the hydraulic cylinders. The ground drive pump servo adjustment hydraulic cylinders (313) swing the ground drive variable displacement pump (211) only by the path defined by the ground speed control lever because there is a mechanical feedback of the swing angle to the ground drive servo adjustment valve (606). This mechanical feedback balances the spool in the ground drive servo adjustment valve (606) and therefore the pressure level between the two hydraulic cylinders at the control edge so that the defined swing angle is maintained.

High-pressure circuit As soon as the ground drive variable displacement pump (211) is swung

out, an axial motion is added to the radial motion of the pump unit. This axial motion displaces the oil in the cylinder space of the rotor and thus acts on the motor unit which converts this energy into a rotating motion by supporting against the fixed inclined disc.

The respective suction side of the ground drive variable displacement pump (211) is pre-stressed via the feed pressure circuit and the corresponding ground drive multi-function valve (713/714). This ensures that the ground drive variable displacement pump (211) is sufficiently filled and that any occurring leaks are compensated.

Since feed pressure is always applied on the suction side of the ground drive variable displacement pump (211) as well as on the return flow side of the ground drive fixed displacement motor (210), this area is referred to as low-pressure side within the high-pressure circuit.

04/04 DO-h-Kap4 4-5

Hydraulic System Dominator 140 - 150 TIC

Description of function:

High-pressure limitation If the system pressure rises above the set maximum value, this

overpressure is relieved to the feed pressure circuit by the ground drive multi-function valves (713/714). The high-pressure limitation should only respond for a short time during operation since the large oil flow which has to be displaced by the heavily pre-stressed valves would rapidly overheat the system.

Flushing device The respective high-pressure side in the high-pressure circuit actuates the

ground drive purging shuttle valve (721) in the ground drive fixed displacement motor (210) so the corresponding low-pressure side has a connection to the motor housing via the ground drive purge pressure control valve (719). Since the pressure setting of the ground drive purge pressure control valve (719) is lower than that of the ground drive feed pressure relief valve (716), a constant oil quantity is exchanged by the ground drive feed pump (209) via the restrictor in the ground drive purge pressure control valve (719).

the ground drive feed pump (209) are driven by the nine pistons (K) arranged radially around the drive shaft (W). In this process, the pistons (K) are pressed against the swing disc (S) by means of the slides (G) due to the feed pressure applied on both sides of the high-pressure circuit (H).

One of the servo cylinders is actuated by the ground drive servo adjustment valve (606) so that this cylinder swings the swing disc (S) according to the direction of travel and the ground speed. During the swinging motion, the pistons (K) make an axial movement on the inclined plane of the swing disc (S) which results in the oil in the filled cylinder space being displaced and in a pressure building up against the resistance at the motor. When the entire oil quantity in the cylinder space has been displaced, the piston (K) rotating with the rotor (R) is pushed back by the feed pressure and against the sloping inclined plane of the swing disc (S) on the lowpressure side. The cylinder spaces in the rotor (R) are thus filled one after the other on the sloping side of the swing disc (S) (low pressure) and then displace this oil quantity on the rising side (high pressure) against the motor unit.

According to the direction of travel, the swing disc (S) is moved to one or the other direction, making high pressure and low pressure change sides as well. The ground speed depends on the oil flow quantity and consequently on the swing angle of the swing disc (S). The swing angle pre-set on the ground speed control lever is maintained by the mechanical feedback from the swing disc (S) to the servo control valve (606).

The low-pressure side is separated from the high-pressure side inside the pump unit above the control bottom (B). For sealing purposes, the cylinder rotor (R) is pushed against the control bottom (B) only by a compression spring.

The exact return of the swing disc to its neutral position is achieved by compressed springs, and this factory setting cannot be modified from the outside. The position of the adjusting lever (V) on the shaft gearing is marked with a punch blow on the servo adjustment housing. This position corresponds to the neutral position of the servo adjustment valve which is achieved within an angle of 8° of the adjusting range.

To align the mechanical neutral position of the adjusting lever (V) with the

G Threaded bushing M Mechanical feedback P Spool S Swing disc V Adjusting lever

both ground drive pump servo control hydraulic cylinders (313) are pressure-loaded, keeping the swing disc (S) stable in any position.

The cable mounted on the adjusting lever (V) moves the spool (P) in the ground drive servo adjustment valve (606) from the neutral position to one or the other direction. Depending on the direction of travel, one of the ground drive pump servo adjustment hydraulic cylinders (313) is thus pressure-relieved whereas the other servo cylinder remains connected to the feed pressure circuit. The movement at the swing disc (S) thus corresponds to the pressure difference between the ground drive pump servo adjustment hydraulic cylinders (313).

The ground drive pump servo adjustment hydraulic cylinders (313) swing the variable displacement pump only by the path defined by the adjusting lever (V) because there is a mechanical feedback (M) of the swing angle to the ground drive servo adjustment valve (606). This mechanical feedback (M) balances the spool (P) in the ground drive servo adjustment valve (606) at the control edge to the neutral position. The pre-set swing angle is thus maintained by the pressure compensation in both ground drive pump servo adjustment hydraulic cylinders (313).

hydraulic neutral position of the variable displacement pump, the spool (P) in the servo adjustment valve is adjusted using the threaded bushing (G). To do this, the bushing (G) is first set to a clearance of X = 14.75 mm (X) from the housing of the ground drive servo adjustment valve (606). A pressure measurement on both sides of the high-pressure circuit determines the respective pressure rise caused by rotating the bushing (G) to one or the other direction. The centre position of the path by which the bushing (G) has been rotated corresponds to the average neutral position.

also driven. In this process, the pistons (K) in the cylinder rotor (R) of the motor unit are pressed against the fixed inclined disc (S) by means of the slides (G) due to the feed pressure applied on both sides of the highpressure circuit. As soon as the variable displacement pump is swung out, the pressure builds up against the nine pistons (K) in the cylinder rotor (R) which is geared to the driven shaft (W), one after the other. Here the pistons (K) support themselves against the inclined plane of the fixed inclined disc (S) and thus convert this energy into a rotating motion against the resistance at the driven shaft (W).

The direction of rotation here depends on the direction of the oil flow and thus on the swing direction of the variable displacement pump, with high pressure and low pressure changing the sides. The motor speed results from the oil flow quantity therefore from the swing angle of the variable displacement pump.

The low-pressure side is separated from the high-pressure side inside the motor unit above the control bottom (B). For sealing purposes, the cylinder rotor (R) is pushed against the control bottom (B) only by a compression spring.

The respective high-pressure side in the high-pressure circuit actuates the ground drive purging shuttle valve (721) in the fixed displacement motor so the corresponding low-pressure side has a connection to the motor housing via the ground drive purge pressure control valve (719). Since the pressure setting of the ground drive purge pressure control valve (719) is lower than that of the feed pressure relief valve, a constant oil quantity is exchanged by the feed pump (209) via the restrictor in the ground drive purge pressure control valve (719).
