An embodiment integrated two-wheel drive module includes a module body, wherein each side portion of the module body extends upward to define a space and an upper end of each side portion extends to one side to define a shoulder portion, a battery and a controller disposed in the module body, a pair of wheels mounted on both side surfaces of the module body, wheel frames disposed in each of the wheels, wherein the wheels are rotatable with respect to the wheel frames, in-wheel motors mounted in each of the wheel frames, joining brackets disposed on a first surface of each of the wheel frames, respectively, a steering device mounted in the module body and connected to each of the wheel frames through respective ball joints, and suspensions mounted between the shoulder portions of the module body and the joining brackets.

A vibration damper of a vehicle wheel is supported on a vehicle body by a damper mount having an elastic body. The vibration damper includes a fluid-filled cylinder, a piston guided in the cylinder, and a piston rod. A wherein a damper chamber is formed in the cylinder on each side of the piston. The damper mount includes a hydraulic pressure chamber connected via a fluid-conducting connection to the damper chambers, whose volumes are respectively reduced when the vehicle wheel is deflected in relation to the vehicle body. In addition, a throttle valve is provided in the fluid-conducting connection, wherein the throttle value comprises a valve body that is displaceable in relation to a valve seat counter to a spring force, and a throttle bore.

A vibration damper, assigned to a wheel of a vehicle, includes a damper cylinder, a damper piston with a piston rod configured to be guided in the damper cylinder, and a damper chamber, formed in the damper chamber on each side of the damper piston. The vibration damper further includes a pressure accumulator, in the form of a gas pressure cushion, connected to the damper chamber lying opposite the piston rod. The vibration damper is mounted on the vehicle body by a damper mount with a rubber-elastic body that is deformable in a shifting direction of the damper piston. A hydraulic pressure chamber is formed in the damper mount, and is connected via a fluid-conducting connection to the damper chambers whose volumes are respectively reduced when the wheel is deflected in relation to the vehicle body. The damper chambers are connected hydraulically to one another via a hydraulic pump driven by a motor. The damper mount includes a spring element that acts on the rubber-elastic body in the shifting direction of the damper piston, such that a spring force of the spring element, in the case of a stationary damper piston and equality of pressure in the two damper chambers, results in forces acting on the rubber-elastic body in the shifting direction of the damper piston to at least approximately cancel one another out.

A mounting bracket assembly for securing a shock absorber to a leaf spring includes a first bracket, a second bracket, a first fastener and a second fastener. The first bracket includes a first fastener receiver and a second fastener receiver. The second bracket includes a first arm, having a third fastener receiver and a fourth fastener receiver, and a second arm having at least one shock mount. The first fastener is received in the first fastener receiver and the third fastener receiver. The second fastener is received in the second fastener receiver and the fourth fastener receiver. The mounting bracket assembly is adapted to clamp the leaf spring with the leaf spring extending between the first bracket, the second bracket, the first fastener and the second fastener.

A vehicle suspension system includes a support member coupled to a vehicle body, a shock absorber connecting the support member and the vehicle body and absorbing the road surface impact, a steering section pivotably mounted on the support member, and an in-wheel motor section coupled to the steering section in an interworking manner and mounted on a wheel to provide driving force.

Provided are a shock absorber and a bracket which are improved in attachment rigidity. A cylindrical portion is shaped by press-forming first and second holes in sheet material (flat plate) and then curving the sheet material into a tube, in which a bridge portion is formed between the first and second holes. The bracket is thus improved to have higher formability as compared to conventional brackets which are not provided with a bridge portion. This improves the accuracy (cylindricity, in particular) of the cylindrical portion. It is then possible to improve the shock absorber in attachment rigidity against a lateral force to the anteroposterior direction of a vehicle in a situation where the bracket is used to attach the shock absorber to the knuckle.

Land vehicles are disclosed. A land vehicle includes a chassis extending in a longitudinal direction, a plurality of wheels supported by the chassis including a pair of front wheels and a pair of rear wheels arranged rearward of the pair of front wheels in the longitudinal direction, a pair of front suspension assemblies each coupled to one of the pair of front wheels and the chassis to support the pair of front wheels for rotation relative to the chassis in use of the land vehicle, and a pair of rear suspension assemblies each coupled to one of the pair of rear wheels and the chassis to support the pair of rear wheels for rotation relative to the chassis in use of the land vehicle.
