Electrohydraulic steering

OSPE

Danfoss is proud to present the next coming product
addition to our range of industry leading products for
electrohydraulic steering – the OSPE. This product will
allow direct electric interface for GPS, row or laser
auto-steering systems, as well as Joystick, or electric
mini steering wheel in the agrculture and
construction market.

The OSPE incorporates all the best features of our
existing OSP and EH valve range as well as several
new and unique additional features. The OSPE
represents a new generation of electrohydraulic
steering products characterized by a high level of
integration and a significantly increased amount of
integrated safety features.

The Danfoss OSPE is designed to allow a simpler
architecture for our customers to comply with
existing steering regulation and safety demands,
when introducing electrohydraulic steering systems.

Furthermore the OSPE will offer the possibility to
enhance the steering feel, and approach steering
characteristics known from automotive vehicles.
Steering behavior can be optimized to suit vehicle
specific conditions for both on road and off road
operation.

Features

‒
‒
‒

•

Optimized for automatic steering.

Eliminates all effect caused by any
part of the electronic or EH-valve
portion.
Makes it easier to get SBW features
homologated.

Possibility to simplify hydraulic
architecture.

source.

TruPath.

‒

Applicable to any GPS steering

‒

systems.

•

Variable steering ratio

Adjust steering aggressiveness to the

‒

current vehicle work situation (in
conjunction with Danfoss SASA
steering wheel sensor and PVED CL
actuator (non-reaction mode only)).
