A front axle of a vehicle, configured for reducing vibration, which is connected to a knuckle having a front wheel disposed thereon through a king pin, in which a gap may be formed between the knuckle and the king pin passing through the front axle and the knuckle, and filled with lubricant oil, and at least one of the king pin and the knuckle may include a plurality of rollers disposed therein, the rollers having an axis parallel to an axial direction of the king pin while circumferences of the rollers are partially buried in at least one of the king pin and the knuckle.

The present invention relates to a new hydraulic stabilizing unit that can be mounted onto any self-steering axle assembly that utilises a pneumatic stabilizing system. The hydraulic stabilizer works in conjunction with the pneumatic stabilizer to eliminate a “dead zone” of the pneumatic system to avoid wheel shimmy and hop conditions associated with out of specification caster angles on the axle.

A damper apparatus includes a shock-absorbing member configured to absorb a shock while restricting movement of a shaft relative to a housing. The shock-absorbing member includes a shock-receiving member configured to come into contact with one member, which is one of a large-diameter portion of the shaft and a restriction portion of the housing, and a pre-compression spring disposed between the other member, which is the other of the large-diameter portion and the restriction portion, and the shock-receiving member in a state where the pre-compression spring is compressed in advance in an axial direction. The pre-compression spring is configured to urge the one member in the axial direction via the shock-receiving member when the large-diameter portion is relatively moved toward the restriction portion beyond a prescribed position.

A method of manufacturing a damping device, notably for a steering tie rod, the said device comprising a rod which extends along a main axis and which is intended to be connected to a first mechanical component, a securing portion which surrounds the said rod and which is intended to be connected to a second mechanical component, and a sleeve made of elastomeric material which is arranged between the rod and the fixing bushing so as, through elastic deformation thereof, to allow at least axial movement of the fixing bushing with respect to the rod, in which method the fixing bushing is offset axially with respect to the rod to force the elastic deformation of the sleeve and the introduction of a corresponding preload, then the sleeve is locked so as to keep it, when the device is at rest, in a state of permanent axial elastic deformation and preload.

An identical steer control mechanism of a radial bar-link trapezoidal swing arm, a method and a multi-wheel vehicle thereof are disclosed. The radial bar-link trapezoidal swing arm is in a right triangle shape, and in combination with a two-dimensional composite control transmission arm of a cross-shaped groove formed by a transverse groove and a vertical groove, an elliptical gauge is shaped; the longitudinal cosine displacement is controlled by the sliders in the transverse groove, and the transverse sine displacement can be controlled by connecting the sliders in the vertical groove after the right-angle end bearing is hinged to connecting rods, the end bearing on the two-dimensional composite control transmission arm, namely the key control point bearing, draws a deflection elliptical trajectory, and the hinged slider to the key control point bearing is connected with a vector control swing arm sliding slot to generate a steering angle βi.

A four-wheeled vehicle includes: a frame; two front suspension assemblies and two rear suspension assemblies connected to the frame; two front wheels operatively connected to corresponding ones of the two front suspension assemblies; two rear wheels operatively connected to corresponding ones of the two rear suspension assemblies; a motor connected to the frame; a front differential and a rear differential operatively connecting the motor to the two front wheels and the two rear wheels respectively; and a steering system. The steering system includes a front steering assembly for steering the front wheels and a rear steering assembly for steering the rear wheels. The front steering assembly includes a user-operated steering input device. The rear steering assembly includes an actuator operatively connected to the rear wheels and operable to modify a steering angle thereof. The actuator is mounted to the frame and is disposed completely rearward of the rear differential.

A trim lock and a centering assembly that provides a centering force between a first portion of a system and a second portion of the system. The centering assembly includes a centering stabilizer that provides a centering force along an axial direction thereof, a trim lock configured and arranged to change a location of one axial end of the centering stabilizer, with respect to the second portion of the system, between an original location and an adjusted location, and to lock the axial end of the centering stabilizer at the adjusted location, a connecting unit for operatively connecting the trim lock with the centering stabilizer, and a mounting member for movably mounting the centering stabilizer with respect to the second portion of the system, wherein the mounting member permits axial movement of the centering stabilizer with respect to said second portion of the system.

A steering and suspension assembly for the rear wheels of an off-road vehicle includes: a) a first suspension component; b) a first steering component; c) a CV axle; d) a portal box assembly; e) a hydraulic steering assembly for moving the first steering component a distance effective to turn the vehicle at least 2° in either direction when the assembly is mounted to a wheel hub; f) a first suspension connection bracket for connecting the first suspension component to the rear wall of the portal box assembly; and g) a first steering connection bracket for connecting the first steering component to the rear wall of the portal box assembly. The portal box assembly includes: i) a housing having a rear wall, a front wall, and a side wall, wherein the rear wall includes a vehicle axle opening effective to receive the end of said CV axle, and wherein the front wall includes an output shaft opening effective to allow an output shaft to extend outward from the housing; ii) a linking mechanism housed in the housing and effective for linking a CV axle received in the vehicle axle opening to an output shaft; and iii) an output shaft operably connectable via the linking mechanism to the CV axle, and effective to rotate upon rotation of the stock axle.

A vehicle with a base frame to which at least two sprung suspensions, in particular sprung wheel suspensions, for driven, non-driven, steerable or non-steerable contact elements, for example wheels, are attached which can be steered by means of a steering knuckle and are located on both sides of the longitudinal direction of travel, in each case transversely to the direction of travel, a tilt frame, tiltable in a tilt axis with respect to the base frame. A steering tube is rotatably attached to the tilt frame in the steering axis and automatically tilts with the tilt frame, at least one track rod connected to the track rod actuating element, and a linear or rotary track rod actuating element rotatable over a guide element. The track rod actuating element is displaced by tilting the tilt frame about the tilt axis and independently thereof by rotating the steering tube about the steering axis in such a way that the steerable contact element is given a steering movement by the track rod actuating element by means of the at least one track rod and no substantial change in the camber of the contact elements takes place during cornering, wherein the vehicle comprises at least one spring damper system which is suitable and provided for reducing a pendulum tilt of a tilt frame about the vertical zero position.

A combination of components forming a steering stabilizer mounting assembly including a stabilizer, a bracket shim, an independent hollow tubular housing with a fixedly attached base washer, and nuts and bolts to fasten the components into place.
