A steering assembly includes a housing having a bore, and a non-plastic support ring disposed within the bore. The non-plastic support ring has an annular wall with an outer periphery and an inner periphery. A plurality of rack engagement features extend radially inwardly from the inner periphery of the annular wall. The plurality of rack engagement features are arranged to engage a steering rack to prevent bending of the steering rack.

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 steering device includes: a housing; and a spring configured to urge the retainer toward the rack bar in the second axis direction, and the rack bar, the retainer, the spring, and the spring holding member being disposed in this order in the second axis direction; the retainer chamfering portion provided on the retainer second end portion near the spring holding member, on a retainer second end portion outer circumference portion, and the retainer chamfering portion formed at a portion which is nearest the spring holding member abutment surface in the retainer second end portion outer circumference portion in a section that passes through the second axis, and that is perpendicular to the first axis, when the retainer main body portion is inclined with respect to the second axis.

A rack and pinion steering system includes a rack housing, a rack bearing, and an adjuster plug. The rack housing defines a rack housing bore extending along an axis. The rack bearing is disposed within the rack housing bore. The rack bearing has a first bearing portion that is biasingly connected to a second bearing portion. The first bearing portion and the second bearing portion extend along the axis between a first rack bearing end and a second rack bearing end. The adjuster plug is disposed within the rack housing bore. The adjuster plug extends along the axis between a first adjuster plug end that engages the second rack bearing and a second adjuster plug end.

A steering system comprises a first engagement member; a second engagement member to be engaged with the first engagement member; a supporting portion to support the second engagement member; and an elastic member at least partially enclosed in the supporting portion to apply a preload to the second engagement member and absorb an impact load. The elastic member has a first deformation under a first load and at least a second deformation under a second load greater than the first load, and a ratio of the first load to the first deformation is less than a ratio of the second load to the second deformation.

A device for pressing a rack against a pinion, comprises a housing, a thrust piece which is shiftably guided in the housing along a pressing axis, a bearing element which can axially be fixed at the housing, an axially pressurized force introduction member, and wedge members which each support on the thrust piece, on the bearing element and on the force introduction member, wherein at least three wedge members uniformly distributed in circumferential direction are provided, and wherein the force introduction member urges the wedge members radially to the outside and the thrust piece axially away from the bearing element.

A rotation-linear motion conversion apparatus (10) includes: a rack bar (30) in which a rack gear (32) is formed; a housing (40) that surrounds the rack bar (30); a pinion shaft (20) including a pinion gear (22) that engages with the rack gear (32) and that is inserted inside the housing (40); and a support part (50) that is provided on an opposed surface (41s1), which is opposed to the rack gear (32), of the housing (40) and that supports the rack bar (30) movably in a longitudinal direction of the rack bar (30).

A steering system includes a rack housing in which a rack shaft is housed, rack ends fitted to respective end portions of the rack shaft and coupled to respective steered wheels, and shock-absorbing members provided between the rack housing and the respective rack ends. When the rack shaft moves in a direction in which an end face of the rack end approaches a restricting surface of the rack housing and thus the rack shaft reaches a position after the shock-absorbing member is compressed by a compression amount, a control unit creates a normal input end through electronic stopper control of reducing an assisting force to be generated by a motor. This restricts movement of the rack shaft in a direction in which the end face approaches the restricting surface.

The present disclosure relates to a steering apparatus and a steering control method. A steering apparatus of the present disclosure comprises: a sensor which measures the steering angle on the basis of the torque of a steering wheel; a steering control module including one electronic control unit that controls a reaction force motor by using information on the steering angle measured by the sensor; and an auxiliary reaction force module which provides a reaction force to a steering shaft or a motor shaft by not applying a current from the electronic control unit during an abnormal operation of the electronic control unit.

A rack and pinion steering system includes a rack housing, a rack bearing, and an adjuster plug. The rack housing defines a rack housing bore extending along an axis. The rack bearing is disposed within the rack housing bore. The rack bearing has a first bearing portion that is biasingly connected to a second bearing portion. The first bearing portion and the second bearing portion extend along the axis between a first rack bearing end and a second rack bearing end. The adjuster plug is disposed within the rack housing bore. The adjuster plug extends along the axis between a first adjuster plug end that engages the second rack bearing and a second adjuster plug end.
