Electric Hydraulic Steering Gear

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

Electric hydraulic steering gear.

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. Assist is reduced at speed for great road feel without the sloppy feel of hydraulic power steering think 76 buick. 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.

A double acting hydraulic cylinder applies a force to the steering gear which in turn steers the roadwheels. Both are attached to the rack and pinion with threaded brass fittings. The hydraulic oil pressure varies from 100 bars to 175 bars depending on the size of the rudder and torque required. Power steering power steering is boost produced by a pump which creates tremendous pressure through the use of hydraulic fluid in most cases.

Electronic power steering system it is the latest type of power steering system in which the hydraulic system from the hydraulic power steering is completely replaced with electric motors and electric sensors instead of using hydraulic force the motor driven by the vehicle s battery is used to apply force on the steering gear and torque. In rotary vane steering gear there is a fixed housing in which two vanes rotate. The hydraulic pressure typically comes from a gerotor or rotary vane pump driven by the vehicle s engine. 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.

Electronic power steering systems eliminate the need for a pump hoses and a drive belt connected to the engine using variable amounts of power. Rotary vane steering gear. The ram type steering gear arrangement produces a considerably high value of torque for a given applied power.
