A rod-end front suspension is provided for an off-road vehicle. The rod-end front suspension comprises a spindle assembly that is pivotally coupled with an upper suspension arm by way of a first rod-end joint and pivotally coupled with a lower suspension arm by way of a second rod-end joint. A steering rod-end joint coupled with the spindle assembly pivotally receives a steering rod. An axle assembly coupled with the spindle assembly conducts torque from a transaxle to a wheel coupled with the spindle assembly. Each of the first and second rod-end joints comprises a ball rotatably retained within a casing. The ball is fastened within a recess between parallel prongs extending from the spindle assembly. A threaded shank extending from the casing is threadably fixated with the suspension arm, such that the spindle assembly may be moved with respect to the casing and the suspension arm.

A steering device includes a steering power unit, a transmission unit, an upper control arm, a steering element, an eccentric bolt and a steering knuckle. The steering power unit has at least one torque-output end. The transmission unit is connected with the torque-output end. The steering element is connected with the transmission unit. The eccentric bolt, installed at the upper control arm, is connected with the steering power unit. The steering knuckle, mounted to a wheel disc, is connected with the steering element and the upper control arm, and used for controlling the wheel disc. The steering power unit drives the steering element to push or pull the steering knuckle for controlling a turning angle, and simultaneously drives the eccentric bolt to have the upper control arm to push or pull the steering knuckle for varying a camber angle of the wheel disc. In addition, a steering method is provided.

A steering system includes a first wheel and a second wheel spaced apart from the first wheel, a first tie rod, a second tie rod, and an electrical actuator. The first wheel is rotatably coupled to a first knuckle, and the first knuckle is pivotable about a first suspension post. The second wheel is rotatably coupled to a second knuckle, and the second knuckle is pivotable about a second suspension post spaced apart from the first suspension post. The first tie rod is coupled to the first knuckle and to a mechanical linkage. The second tie rod is coupled to the second knuckle and the mechanical linkage. The electrical actuator is coupled to the mechanical linkage so that movement of the electrical actuator translates the mechanical linkage axially, which adjusts the orientation of the wheels relative to the suspension posts.

A wheel carrier assembly for a front axle or rear axle of a motor vehicle, with a wheel carrier part on which a link for a control arm assembly, a fixing device for a damper strut and a recess for a wheel bearing are provided. The wheel carrier part includes an air guide device for supplying air to a disk brake assembly, which as brake parts has at least a brake disk and a brake caliper. The wheel carrier part has a circumferentially hollow wheel carrier housing part. The air guide device includes at least one air inlet opening and at least one air outlet opening directed onto a brake part.

The application discloses a preparation method for an aluminum alloy cavity casting filled with special-shaped foamed aluminum. The preparation method includes: preparing special-shaped foamed aluminum in a first mold by adopting a powder metallurgy foaming method; fixing the special-shaped foamed aluminum coated with the soldering flux in a second mold after the special-shaped foamed aluminum is coated with soldering flux; and casting by using molten aluminum alloy. According to the preparation method for the aluminum alloy cavity casting filled with the special-shaped foamed aluminum, the overall strength of the casting can be improved while the wall thickness of the casting is reduced to meet the requirement that the overall quality of the casting is not increased.
