METHOD FOR USING ULTRASOUND TO LOCK A PLASTIC PLUG THAT PLUGS A STEERING BOX
20200130724 · 2020-04-30 · ·

A method includes a rotation locking step during which the rotation of the threaded hub about the central axis is blocked by heating a portion of the plug to soften, then by forcing the softened thermoplastic material to penetrate into, and then solidify in, a female cavity hollowed in the wall of the orifice to constitute a male member which fits into the female cavity. The female cavity forms, against the action of the male member, a guiding end stop preventing the male member, and therefore the hub, from rotating about the central axis to oppose any rotary screwing/unscrewing of the plug and maintaining a degree of freedom in axial translation along the central axis of the male member within the female cavity, so as not to impede a sliding of the hub and of its screw thread along the central axis against the wall.

Rack bushing and steering device

A clearance is created between an inner circumference of a bushing main body (2) which surrounds a rack (5) across a row of rack gear teeth (50) and an outer circumference of the rack (5), and two supporting surfaces (21A, 21B) which face each other with a bushing main body axis O therebetween and a supporting surface (21C) which faces a back surface of the rack (5), each extending along an x-axis direction, are formed on the inner circumference of the bushing main body (2). The rack (5) in a neutral state is supported by the two supporting surfaces (21A, 21B) so as to be displaceable along a z-axis direction, and the rack (5) in operation is stably supported by the three supporting surfaces (21A-21C) at three places. A groove bottom position of an annular elastic member attachment groove (24), which is formed on an outer circumference of the bushing main body (2), is offset toward the support surface (21B) only in an area on a support surface (21B) side from the bushing main body axis O, and therefore an elastic ring (3) attached to the elastic member attachment groove (24), protrudes above an outer circumferential surface of the bushing main body (2), but only in the area on the support surface (21B) side from the bushing main body axis O.

ISOLATED STEERING RACK YOKE

An assembly includes a housing and a steering rack supported by the housing. The assembly includes a plug supported by the housing. The assembly includes a yoke supported by the housing between the steering rack and the plug. The assembly includes a monolithic dampener between the plug and the yoke, the monolithic dampener extending away from the plug toward the steering rack along the yoke.

Steering rack wear compensator
10563745 · 2020-02-18 · ·

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.

VEHICLE STEERING

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.

Steering device
11939004 · 2024-03-26 · ·

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.

Method for adjusting steering system and adjustment apparatus for steering system

A method for adjusting a steering system and an adjustment apparatus for a steering system are provided which allow a clearance between a support yoke and a yoke plug to be appropriately set. When a yoke plug is loosened which has been temporarily fastened to a degree that a support yoke is subjected to elastic compressive deformation, the yoke plug is loosened to a position where a clearance C between the support yoke and the yoke plug reaches a target clearance using, as a reference, a position where a rate of a change in an axial position of the yoke plug with respect to an angular position of the yoke plug increases rapidly.

Rack bar support apparatus of vehicle steering apparatus
