A wear compensator to compensate wear between a rack and a pinion including a yoke plug, a pin affixed to the yoke plug, jaws that surrounds the pin, a disc spring sandwiched between the yoke plug and the jaws, a stage compensator that receives and slides along the jaws to provide a frictional force, a rack guide in contact with the rack, a spring extending between the stage compensator and the rack guide, wherein when the rack guide transfers to the stage compensator a first load above a predetermined threshold, the frictional force overcomes prevents the spring disc to push the stage compensator towards the rack, and when the rack guide transfers to the stage compensator a second load below the predetermined threshold, the frictional force allows the spring disc to push the stage compensator towards the rack.

A multi-strata radial damper configured to dampen forces exerted in a radial direction between a rack bar of an automobile and a bushing sleeve protecting the rack bar. The radial damper may include a stratum made of a polymer material. The radial damper may additionally dampen forces exerted in an axial direction between the tie rod and the bushing sleeve.

Embodiments of devices for converting continuous rotational motion into oscillating motion are disclosed herein. In one embodiment, an oscillation device can include an input shaft that rotates about a first axis, a portion of the input shaft defining an eccentric section that defines a second central axis offset from the first axis, a connector rotatably coupled around the eccentric section, an oscillating shaft offset from the input shaft that rotates about a third axis, and a pin coupled to the oscillating shaft and extending towards the connector. The connector includes a sleeve slidably receiving an end of the pin, and continuous rotation of the input shaft about the first axis causes an eccentric movement of the connector, and the eccentric movement of the connector oscillates the sleeve along the pin and oscillates the pin with respect to the oscillating shaft, thereby oscillating the oscillating shaft about the third axis.

According to the present embodiments, noise can be reduced by compensating for clearance caused by the wear of a rack bar support member, assembly convenience can be improved by simplifying a structure, and an installation space can be easily ensured by reducing the overall size of a steering apparatus.

A rack guide bearing for meshing a pinion and vehicle steering system rack, the guide bearing including a wall, a first portion is tubular and defines an axis and internal channel around the axis opening at the guide bearing first end, and opening onto a second portion of the wall opposite the first end, an internal channel section transverse to the axis and inserts the rack into the channel according to the rack axis parallel to the guide bearing axis, the guide bearing including an internal channel inner surface of the guide bearing wall's first portion and an inner surface of the guide bearing wall's second portion, the inner surfaces are in slipping contact with a slipping surface of the rack opposite to a toothing of the rack, when the rack is inserted inside the first portion of the wall's internal channel according to the axis of the rack.

A dual-pinion electric power steering device has: a rack shaft that causes a turnable member to turn; a first pinion shaft to which a steering force from a steering wheel is transmitted; a first rack teeth disposed on the rack shaft and capable of meshing with the first pinion shaft; a second pinion shaft to which a rotational driving force from an assist motor is transmitted; a second rack teeth disposed on the rack shaft and capable of meshing with the second pinion shaft; a first pressing member disposed across the rack shaft from the first pinion shaft and configured to press the rack shaft toward the first pinion shaft; and a second pressing member disposed across the rack shaft from the second pinion shaft and configured to press the rack shaft toward the second pinion shaft. The first pressing member has a lower rigidity than the second pressing member.
