A suspension apparatus for a vehicle may include: a member part including a side member part extended in a first direction and a cross member part extended in a second direction; a pair of knuckle parts spaced apart from each other in the second direction, and coupled to and supported by a wheel; and a posture maintenance part supported by the member part, having both sides connected to the pair of knuckle parts, respectively, and configured to absorb shock applied from a road surface and adjust a relative height between the pair of knuckle parts.

A stop washer for an elastomeric bearing is manufactured as a single unit from a sheet metal blank and furnished with a surface protection. In addition to its function as a path limiter, it has at least one of the following functions by a structure integrated into the forming process of the sheet metal blank, namely the function of a thread and/or anti-rotation protection. Furthermore, an elastomeric bearing with such a stop washer and a subframe equipped therewith are conceivable.

The present invention comprises a trailer main frame with a first rocker assembly and a second rocker assembly pivotally attached to the trailer main frame wherein the rocker assemblies are attached to leveling means such as but not limited to hydraulic and or air system between the trailer main frame and the rocker assemblies.

Disclosed is a self-balancing device for self-propelled off-road RV box body. The self-balancing device includes an auxiliary beam body for connecting with a bottom end of the RV box body, a front triangular balance beam body, a rear triangular balance beam body and an axle-holding device for connecting with a RV chassis girder. The front triangular balance beam body and the rear triangular balance beam body are arranged close to both ends of the auxiliary beam body respectively. The axle-holding device is arranged between the front triangular balance beam body and the rear triangular balance beam body. Both the front triangular balance beam body and the rear triangular balance beam body include a hard limit structure for limiting a swing angle of the RV box body. The axle-holding device includes a soft limit structure for horizontally resetting the RV box body.

An apparatus and methods are provided for a front structural bulkhead for improving the strength of an off-road vehicle chassis. The chassis is a welded-tube variety of chassis that includes a front portion and a rear portion that are joined to an intervening passenger cabin portion. Frontward stays and a bulkhead mount couple the front structural bulkhead to the front portion. Bulkhead mount pillars and a bulkhead mount crossmember couple the front structural bulkhead to the passenger cabin portion. The front structural bulkhead includes a modular chassis for supporting drivetrain components that are operably coupled with front wheels of the vehicle. The front structural bulkhead includes upper and lower mounting points configured to receive front suspension controls arms. The upper and lower mounting points are configured to allow the front wheels to move vertically due to the vehicle traveling over terrain.

A suspension apparatus for a vehicle may include: a member part including a side member part extended in a first direction and a cross member part extended in a second direction; a pair of knuckle parts spaced apart from each other in the second direction, and coupled to and supported by a wheel; and a posture maintenance part supported by the member part, having both sides connected to the pair of knuckle parts, respectively, and configured to absorb shock applied from a road surface and adjust a relative height between the pair of knuckle parts.

The invention relates to an assembly comprising a bushing with a center line L, having an inner sleeve with a mounting bore, an outer sleeve and an elastomeric spring member extending along a height H along the center line L. In one embodiment, the outer surface of the inner sleeve, the spring member and the inner surface of the outer sleeve are on each side of the center line L substantially parallel. On at least one side of the longitudinal center line L, the outer surface of the inner sleeve, the spring member and the inner surface of the outer sleeve extend at an angle to the center line L. An outer surface of the outer sleeve is substantially parallel to the center line L along the height H. Another embodiment of an assembly according to the invention comprises a bushing with a mounting bore that extends at an angle to the center line L. The bushing according to the invention is compact, can be easily manufactured and assembled, take up a high load and can be adjusted to the direction along which forces act on the bushing.

A wheel suspension for a vehicle axle of a two-track vehicle, having a wheel carrier carrying a vehicle wheel, which is able to be articulated to a vehicle body via a multi-link assembly, which multi-link assembly has a trapezoidal link in the form of a four-point link with two connection points on the body side and two connection points on the wheel carrier side. The trapezoidal link connection points on the wheel carrier side are designed with a higher elastic longitudinal compliance, that is, softer, than the trapezoidal link connection points on the body side.

A front suspension apparatus in which a front side of a suspension arm can be cut off from a subframe at the time of a small overlap collision without a complication of structure and formability. A front suspension apparatus in which a lower arm from which a front wheel is suspended is provided, and a front arm portion and a rear arm portion of the lower arm are axially supported by axially supporting portions of a subframe is characterized in that an axially supporting portion of the front arm portion is joined to the subframe at a joined portion extending in a vehicle width direction, a joined portion extending in an up-down direction, and a joined portion extending in a front-rear direction, and a joining strength of a joined portion in the front-rear direction is lower than a joining strength of the joined portion in the up-down direction.

A subframe according to an embodiment is a subframe that holds a suspension device and includes: a pair of side members extending in a front-back direction; a first cross member coupling the side members to connect the side members in a vehicle width direction; a second cross member disposed away from and behind the first cross member and coupling the side members to connect the side members in the vehicle width direction; a first vehicle body attachment point disposed further backward than the first cross member and formed to extend outward in the vehicle width direction from the side member; and a second vehicle body attachment point disposed further backward than the first vehicle body attachment point and formed to extend outward in the vehicle width direction from the side member, and a suspension arm extending from the suspension device is attached to the side member.
