Remy offers three types of steering racks. Each unit is remanufactured to OE specifications and is tested to ensure that the part performs functionally in the same way as a new part, has an extended lifetime and is safe.
Manual Steering Racks
The steering unit consists of a main rack shaft with a pinion. The pinion shaft is attached to the vehicle steering wheel. This type of steering rack is becoming increasingly popular again in conjunction with an electric steering column.
Hydraulic Steering Racks
The main rack shaft in a power steering rack has a piston attached to the shaft and the pinion has a control valve built around it. When the pinion valve is turned, it controls the fluid that is supplied by the power steering pump and directs the fluid to a piston attached to the main rack shaft then the fluid forces against the piston to give the steering assist. A Hydraulic steering rack is fitted with a hydraulic or electric hydraulic power steering pump.
Electric Steering Racks
Electric steering racks have become increasingly important. EPS eliminates many HPS components such as the pump, hoses, fluid, drive belt, and pulley. For this reason, electric steering systems tend to be smaller and lighter than hydraulic systems. The EPS electronic control unit (ECU) calculates the assisting power needed based on the torque being applied to the steering wheel by the driver, the steering wheel position and the vehicle’s speed. The EPS motor rotates a steering gear with an applied force that reduces the torque required from the driver.
Remy’s range of remanufactured electric power steering racks is one of the largest available in Europe.
