A centering member including a first section configured and arranged to produce a pulling force along a longitudinal axis thereof and a second section configured and arranged to produce a pushing force along a longitudinal axis thereof, wherein the first section and the second section are configured and arranged such that the longitudinal axis of the first section is aligned with the longitudinal axis of the second section. There is a first mounting means attached to a first distal end of the centering stabilizer and a second mounting means attached to a second distal end of the centering stabilizer Preferably, the first section comprises a gas push-type spring and the second section comprises a gas traction spring.

A coupling device includes two coaxial shafts, namely a tubular outer shaft and an inner shaft, capable of rotating about a reference axis; a wrap-around raceway formed on a first one of the coaxial shafts; an oblique raceway formed on the second coaxial shaft and a play take-up rail provided with a complementary raceway and movable relative to the second coaxial shaft parallel to a plane perpendicular to the reference axis. A row of balls is positioned to run parallel to the reference axis on the wrap-around raceway, the oblique raceway and the complementary raceway, to guide the two coaxial shafts relative to each other in translation.

A tension rod supporting part (14) is provided at a sub-frame front structure (10) of a front part of a front sub-frame (5); the side member (6) is disposed upward in one side and extended rearward from the tension rod supporting part (14); a rack arrangement step (A) opened downward for arranging a steering rack (55) is formed behind the tension rod supporting portion (14) and under the side member (6); and a stabilizer support part (62) is provided in the rack arrangement step (A).

A wheel-mounting assembly for an agricultural utility vehicle includes a chassis and a telescopic axle arrangement fixed to the chassis. The telescopic axle arrangement includes an inner axle telescopically received in an outer axle, which is fixed to the chassis. A wheel-support assembly is mounted to an outboard end of the inner axle. A steering-control actuator is connected between the inner axle and the wheel-support assembly. The steering-control actuator is connected to the inner axle through an opening provided in the outer axle, which allows the steering-control actuator to translate together with the inner axle when track width is adjusted.

A rack and pinion steering system includes a housing, a rack, a pinion gear, and a radially preloaded rack bearing. The rack is supported by the housing, and the pinion gear is meshed to the rack. The radially preloaded rack bearing is supported and preloaded to the housing and is preloaded to the rack.

In a steered shaft in a steering system, when a section of a first end portion having a prescribed length shorter than a length from an end face to an outer peripheral rolling groove is defined as a first section, a section of the first end portion other than the first section and adjacent to the outer peripheral rolling groove is defined as a second section, a section, in the outer peripheral rolling groove, starting from a boundary between the second section and the outer peripheral rolling groove and having a prescribed length shorter than an axial length of a section along which the outer peripheral rolling groove extends is defined as a third section, a maximum value of a hardening depth in the second section is larger than a hardening depth in the first section.

The system and method of making an asymmetrical buckling portion in a linkage member that is formed at the same time a hexagonal holding feature is being formed. The presence of the elongated groove drives the force of a buckling event asymmetrically through the inner tie rod ball stud near the area of failure, which influences the tie rod assembly to buckle in the direction of the groove, prior to other components in the linkage system and thus negates the effects of inner tie rod ball stud run-out tolerances that are present in conventional inner tie rod ball studs formed by machining.

The tie rod assembly union includes a tube sleeve and a tie rod shaft that extends into the tube sleeve such that the tie rod shaft and the tube sleeve overlap with one another. In the overlapping area, each of the tie rod shaft and the tube sleeve has at least one set of openings. A C-shaped clamp is disposed about the tube sleeve. The clamp has a curved inner surface which engages both tube sleeve halves. The clamp has a first set of apertures which are spaced outwardly from the curved inner surface and a second set of apertures which extend to the curved inner surface. A first fastener extends through the first set of apertures to tighten the clamp onto the tube sleeve. A second fastener extends through the second set of apertures and through aligned openings in the tie rod shaft and tube sleeve.

A socket assembly includes a housing having an inner bore extending along a central axis between a closed first end and an open second end. At least one bearing is disposed in the inner bore, wherein the at least one bearing has a bearing surface and a support surface opposite the bearing surface. The socket assembly also includes a ball stud having a shank portion extending outwardly from the housing through the open second end and a ball portion disposed in the inner bore. At least one preload washer biases the at least one bearing into engagement with the ball portion of the ball stud. The at least one preload washer has an outer coating of a low friction, heat insulating material.

An electric-propulsion car includes: a main frame, a front axle unit, a rear axle unit, wherein the axle units each have an auxiliary frame for supporting the axle units and two suspension units that connect two respective wheel supports to the supporting auxiliary frame, wherein at least one of the axle units is a motorized axle with steering wheels including, mounted on said auxiliary frame, an electric motor for actuating the rotation of the wheels, a control unit for controlling said electric motor, a transmission unit for connecting the electric motor to the wheels, and a steering device for steering the wheel supports, and wherein each one of the main frame and auxiliary frames includes a reticular lattice structure including boxed elements made of steel, each one of the main frame and auxiliary frames being adapted to be pre-assembled separately and then assembled together. The main frame and auxiliary frames include elements made up of multiple segments connected together and derived from at least one boxed element made of high-tensile steel, wherein the at least one boxed element has at least one notch formed on at least one side of the boxed element without involving an ulterior side of the boxed element, the notch being made on the at least one side at the point where said ulterior side of the boxed element has to be bent to obtain the configuration of the finished boxed element.
