A rack biasing device includes a rack guide configured to guide movement of a rack shaft, a cylindrical guide member attached to a rack housing, an annular first sealing member configured to provide a seal between the guide member and the rack guide, a biasing member disposed on one side of the rack guide opposite to the rack shaft, an engaging member configured to cause the biasing member to generate biasing force to push the rack shaft toward a pinion shaft, and a second sealing member configured to provide a seal between the guide member and the rack guide, and abut against the engaging member. The rack guide has an annular distributing portion in an end portion that faces the engaging member.

A rack supporting device for vehicle steering systems includes: a steering housing having a steering gear installed therein; a rack bar longitudinally inserted into the steering housing to engage with the steering gear; a tapered passage defined in an inner circumference of the steering housing, wherein the tapered passage is eccentric with an axial center of the steering housing; a rack bushing inserted between an inner circumference of the tapered passage and an outer circumference of the rack bar so that the rack bushing moves along the tapered passage and pushes the rack bar to the steering gear; and an elastic member mounted to one side of the tapered passage to provide an elastic pressing force for pushing the rack bar to the rack bushing.

The present embodiments relate to a rack bar supporting device of a vehicle steering apparatus, which may include: a support yoke configured to be inserted into a cylinder of a gear box and configured to have a support recess famed on a front surface thereof to support a rack bar positioned in the lateral direction therein and a yoke hollow formed on a rear surface thereof so as to receive an elastic member; a yoke plug configured to have a plug hollow famed on a front surface thereof to receive the elastic member for supporting the support yoke toward the rack bar and configured to be connected to the cylinder of the gear box; and damping members configured to protrude from a rear surface of the support yoke so as to be supported by a front surface of the yoke plug when an impact load is reversely transferred from the road surface through the rack bar.

A rack adjuster plug assembly for a steering system of a vehicle includes an outer bearing seat coupled to a rack housing and in abutment with a rack bearing. Also included is an inner spring seat disposed within a central aperture of the outer bearing seat. Further included is a spring disposed between the rack bearing and the inner spring seat.

A steering assembly having an inner steering member; an outer member, where the inner steering member is adapted to translate relative to outer member; and a bearing component disposed around a portion of the inner steering member, where the bearing component includes a bearing having a unitary substrate and a polymer layer overlying the substrate, where the bearing has a generally arcuate shape and is adapted to support the inner steering member disposed in the outer member, where the bearing has a support region for supporting an inner steering member, and a plurality of feet comprising a first foot and second foot spaced apart from each other such that the support region extends there between, and where the first and second feet extend in radial direction beyond the support region such that upon assembly between inner steering member and outer member, wherein the bearing exerts a force against the inner steering member.

A steering assembly including an inner steering member; an outer steering member; a leaf spring disposed between the inner steering member and the outer steering member and adapted to bias the inner steering member, wherein the leaf spring comprises an inner portion and a plurality of outer portions, wherein the outer portions comprise end portions of the leaf spring that are folded over such that the outer portions overlie the inner portion, forming a folded edge; and a low friction layer supported by the leaf spring.

A supporting apparatus for a steering gear box includes a pressing yoke part for supporting a side surface of a rack bar to be engaged with a steering input gear in a shape to wrap the side surface of the rack bar, a supporting yoke part provided in a mounting groove together with the pressing yoke part, an elastic link part formed of an elastic material and extending from the pressing yoke part to be inserted into the supporting yoke part, a cover part provided at a position opposite to the supporting yoke part and shielding an inlet of the mounting groove, and a pressing part located between the supporting yoke part and the cover part and pressing the supporting yoke part by a predetermined elastic force.

A vehicle steering assembly comprises a steering member with a rack portion having rack teeth, a pinion gear having pinion teeth configured to be engaged with the rack teeth, a yoke support assembly supporting the steering member in a housing, and a ball nut operatively connected to the steering member. The pinion gear divides the steering member into a first side having the yoke support assembly outboard of an area of engagement of the rack and pinion teeth and a second side having the ball nut. The yoke support assembly includes complementary convex and concave bearing surfaces configured to provide relative rotation between the convex and concave bearing surfaces. The yoke assembly also includes a spring member configured to produce a variable rate spring force to maintain an engagement between the rack and pinion teeth.

A damping stopper is interposed between two members axially displaced relative to each other and is provided with an elastic body which, when the interval between the two members decreases, is axially compressed by the two members and expands radially outward. In the elastic body, a second member suppressing the expansion is located in one axial region and attached to the outer periphery. When axially compressed by the two members, the elastic body expands while receiving resistance by the second member. The expanding elastic body contacts the side wall of one of the two members.

An assembly includes a steering rack. The assembly includes a first pinion meshed with the steering rack. The assembly includes an internal gear coupled to the first pinion. The assembly includes a second pinion meshed with the internal gear.
