Electric Hydraulic Steering Gear

Modern electric steering assist is replacing hydraulic assist on many high end modern cars and trucks.

Electric hydraulic steering gear.

The hydraulic oil pressure varies from 100 bars to 175 bars depending on the size of the rudder and torque required. In rotary vane steering gear there is a fixed housing in which two vanes rotate. Electronic power steering systems eliminate the need for a pump hoses and a drive belt connected to the engine using variable amounts of power. The configuration of an eps system can allow the entire power assist system to be packaged on the rack and pinion steering gear or in the steering column.

This pressure applies force to the steering gear which in turn reduces the amount of physical effort. The steering coupler connects the steering wheel and shaft to the steering gear. The hydraulic pressure typically comes from a gerotor or rotary vane pump driven by the vehicle s engine. Rotary vane steering gear.

Assist is reduced at speed for great road feel without the sloppy feel of hydraulic power steering think 76 buick. Hydraulic power steering systems work by using a hydraulic system to multiply force applied to the steering wheel inputs to the vehicle s steered usually front road wheels. Both are attached to the rack and pinion with threaded brass fittings. The ram type steering gear arrangement produces a considerably high value of torque for a given applied power.

If your vehicle has hydraulic power steering there are two main power steering hoses. Jeep owners should check out the crown power steering gear box and omix ada steering gear box. The high side high pressure hose and the low side low pressure hose.
