A shock absorber assembly having a wheel assembly including first and second coupling points, and first and second shock absorber elements. Each shock absorber element includes a housing portion defining a bore, and a rod slidably coupled within the bore such that the shock absorber element has a variable length. Each rod is coupled to a respective coupling point of the wheel assembly. The shock absorber assembly is arranged to maintain the relative positions of the first and second housing portions such that the longitudinal axis of the first bore has a generally fixed relationship with respect to the longitudinal axis of the second bore.

A damper assembly for a vehicle suspension system includes a first damper and a second damper. The second damper includes a housing having a wall that at least partially surrounds at least a portion of the first damper, the volume between the wall and the first damper defining a chamber, and the wall defines an aperture. The second damper also includes a piston positioned within the chamber, a conduit defining a flow path that includes the aperture, and a flow control device disposed along the flow path. The second damper is configured to provide a damping force that varies based on the position of the piston within the chamber.

Safe protection equipment for all vehicles will significantly reduce the collision force by spring or liquid cylinder when the vehicle bumps to obstacle or two vehicles collide with each other. This equipment can be used on both front and rear of the vehicle. Combination of springs or liquid cylinder with different elasticity can reduce the collision smoothly. This equipment will protect both vehicles and drivers without changing the current air-bag protection system. It will significantly reduce the damage for serious collision accidents. This equipment is attached to the vehicle chassis with a pair of pad to pass the reduced collision force to the elastic tire when colliding vehicles are running in straight line. Normally vehicle running in straight line has high speed and the collision force is strong. The elastic tire can reduce the collision force further.

A hydraulic torque compensation device comprises a pair of housings, a first housing including a first high pressure liquid chamber and a second low pressure liquid chambers, a second housing having a third high pressure liquid chamber, a fourth accumulator chamber, and a fifth low pressure chamber that is defined by a wall and an end of the second housing. A first main duct links the first chamber of the first housing to the third chamber of the second housing. A second main duct links the second chamber of the first housing to the fifth chamber of the second housing. Each housing also include a piston, the first chamber between a first piston body and an end of the first housing and the third chamber between a second piston body and the wall. The device ensures a counter action to engine loads when a positive torque is applied.
