Product catalog summary
Introduction to EHPS Electrohydraulic Power Steering
The electrohydraulic steering system from Sauer-Danfoss offers several benefits including high steering pressure, low noise levels, manual steering capability in case of pump failure, and reduced side acceleration in articulated vehicles. It also supports CAN bus interface and can be combined with PVG 32 proportional valves.
Off-road and On-road Approval
EHPS systems can be approved for road use with active electrical steering due to the availability of active hydraulic backup. For off-road use, full 'steer by wire' systems are permissible, allowing joystick-only steering.
EHPS Steering Valve Features
EHPS systems are suitable for loaders, forklifts, dumpers, tractors, and harvesters, providing electrically actuated steering for improved productivity and driver comfort. The system supports both low and high-speed driving adjustments.
EHPS System Types
  • EHPS Type 0: A purely hydraulic system with low noise and high steering pressure, optimized for manual steering.
  • EHPS Type 1: Includes an electric activation unit for both hydraulic and electrical steering, prioritizing hydraulic steering.
  • EHPS Type 2: Features a microcontroller with steering software for 'steer by wire' with active hydraulic backup, offering high safety and variable steering ratios.
General Characteristics
The EHPS system provides low noise levels, high steering pressure, improved manual steering, reduced side acceleration, and options for integrated priority and proportional valves.
Company Overview
Sauer-Danfoss is a global manufacturer of hydraulic and electronic components, specializing in solutions for the mobile off-highway market. They offer a wide range of products including motors, pumps, displays, steering systems, and more, with a strong focus on customer support and global service.
