Embodiment Construction

[0016] Referring now to the figures, where the invention will be described with reference to specific embodiments without limiting the invention and in accordance with exemplary embodiments of the present invention, figure 1 An electric power steering (EPS) system 10 for a motor vehicle is shown. The EPS system 10 includes a rack and pinion type steering mechanism 12 consisting of a toothed rack (not shown) and a pinion (not shown) located below a gear housing 14 . The steering wheel 16 is coupled to an upper steering shaft 18 . When the steering wheel 16 is turned, the upper steering shaft 18 connected to the lower steering shaft 20 and universal joint 22 turns the pinion. Rotation of the pinion moves the toothed rack which moves tie rods 24 (only one shown) which in turn move knuckles 26 (only one shown) which turn wheels 28 (only one shown).

[0017] EPS assist torque is provided by a steering assist unit 30 including a controller 32 and an electric motor 34 . The contro...

Abstract

According to one exemplary embodiment of the present invention a steering mounting assembly to couple a rack and pinion steering mechanism to a vehicle is provided. The steering mounting assembly includes a first spherical washer to interface with the rack and pinion steering mechanism. The steering mounting assembly further includes a second spherical washer to interface with the vehicle and the first spherical washer. The first spherical washer and the second spherical washer form a relative angle between the rack and pinion steering mechanism and the vehicle. The steering mounting assembly further includes a ring retainer to retain the first spherical washer and the second spherical washer.

Description

technical field [0001] The present invention relates to spherical washer assemblies, and more particularly to spherical washer assemblies suitable for use in electric power steering systems. Background technique [0002] In an electric power steering (EPS) unit, an electric motor drives a worm shaft and a worm gear to provide assist torque to the rotation of the steering shaft. This reduces the effort required to drive the vehicle. In certain applications, the mounting interface between the EPS housing and the vehicle can affect the responsiveness and feel of the steering system. In some applications, vehicle construction can prevent a flush mounting interface between the vehicle and the EPS housing. [0003] Accordingly, it would be desirable to provide a spherical washer assembly for mounting an EPS housing to a vehicle without the aforementioned disadvantages. Contents of the invention [0004] According to an exemplary embodiment of the current invention, a steering...
