BUSH HOG® UTILITY VEHICLE WORKSHOP MANUAL – SECTION 7: STEERING SYSTEM
DESCRIPTION
STEERING
The UTV rack and pinion steering (Figure 1) is common in many automotive systems. The rack is a flat gear that extends outward from both ends of the assembly. A tie rod end connects the rack to the suspension strut assembly.
NOTICE: The suspension struts are described in the Suspension Section of this manual.
The pinion is a rotary gear attached to the steering shaft assembly. When the operator rotates the steering wheel the steering shaft turns the pinion gear which drives the rack in a back and forth movement.
The rack and pinion gear set converts rotary steering wheel motion into linear motion needed to turn the wheels. The rack and pinion also provides gear reduction making it easier to steer the machine.
The tie rods connect to a steering arm on the struts used for turning the strut. The wheels and hubs are mounted to the strut. See the section entitled Suspension for a description of the strut assemblies.
