A power steering system includes a steering column assembly, a steering gear assembly, and a pressure sensor, and a torque sensor. The steering column assembly has a steering shaft and the steering gear assembly is operatively connected to the steering shaft. The steering gear assembly has an input shaft that extends through a valve housing and extends into a rack housing. The pressure sensor is arranged to provide a pressure signal indicative of a fluid pressure of at least one of a first cavity and a second cavity disposed within the rack housing.

The present invention is a steering system for a beam-type solid axle arrangement. The steering system is designed to operate in conjunction with the triangulated link-style suspension system with zero bumpsteer during suspension travel and negligible bumpsteer during articulation. Accurate steering throughout suspension operations is satisfied with mechanical linkages that include a slow ratio rack and pinion gearset and unique augmented chain and sprocket assembly. The slow ratio of the rack and pinion gearset ensures negligible bumpsteer during articulation, thereby leading to negligible if any bumpsteer throughout operation of the suspension system. Meanwhile, augmentation of the chain and sprocket assembly defines a steering quickener effect thereby speeding up the rack and pinion gearset and restoring quick steering response. Effortless steering is ensured by appropriate use of electric or hydraulic assist devices.

A vehicle steering assembly that includes a housing, a pinion shaft, a seal, a protector and a dust cover. The housing defines a bore with the pinion shaft extending therethrough. The seal is disposed within the bore spaced apart from the end of the housing. The seal extends around the pinion shaft creating a seal therebetween. The housing and the pinion shaft define an annular space therebetween and between an opening at one end of the housing and the seal. The protector is fitted to the housing covering a portion of the opening and the annular space. The protector has a shaft receiving opening with the pinion shaft extending therethrough and out of the housing. The dust cover is attached to the housing completely covering the protector and the opening of the bore.

The present invention is an improved version of the steering system described in U.S. patent application Ser. No. 17/115,573. The prior steering system features effortless steering input from the driver and negligible bumpsteer during suspension operation. Such extraordinary steering performance is realized with the use of costly and complex electric assist devices and control devices. The present steering system includes an alternative electric assist device which allows for the removal of the costly and complex electric assist devices in the prior steering system. The present steering system also includes a novel hydraulic control valve with a solenoid valve-plunger mechanism. The mechanism prevents premature wear or destruction of the rack and pinion gearset. The use of the alternative electric assist device and hydraulic control valve enables the present steering system to preserve the extraordinary steering performance featured in the prior steering system concurrent with a reduction in cost and complexity.
