An active mechanical safety device for the compensation of the impacts on a vehicle, comprising a connecting element configured to be constrained to a suspended mass of a vehicle, a respective adjustment element configured to be constrained to the suspended mass and to be positioned between the connecting element and a respective shock absorber element of said vehicle, wherein the adjustment element, following an external stress to which the vehicle is subjected, is movable between a first position, wherein the adjustment element is configured to approach the connecting element to the shock absorber element, and a second position, wherein the adjustment element is configured to move the connecting element away from the shock absorber element.

A hydraulic flow adjuster includes a first hydraulic tank, a second hydraulic tank, and a piston actuator. A first piston operates within the first hydraulic tank and a second piston operates within the second hydraulic tank. The piston actuator adjusts a relative position of the first piston in the first hydraulic tank and a relative position of the second piston position in the second hydraulic tank, such that the relative position of the first piston in the first hydraulic tank is the same as the relative position of the second piston in the second hydraulic tank.

A strut mount cap is provided on an upper surface of a strut mount, and is configured to close a hole housing a fastening component for the strut mount and a shock absorber. The strut mount cap includes a cap body configured to close the hole, an annular water stop lip provided on an outer periphery of the cap body and in elastic contact with the upper surface of the strut mount to prevent water from entering the hole, a press-fit tube provided on a back side of the cap body and held on an inner peripheral surface of the hole by being press-fitted into the hole, and a check valve configured to open the hole when an internal pressure in the hole is equal to or higher than a preset pressure, and close the hole when the internal pressure is lower than the preset pressure.

In a vehicle suspension, a preload is adjusted by selective engagement of cam surfaces of different heights with a cam receiving part by rotation of an adjuster part, the adjuster part includes a vertical wall part erected in an axial direction of a spring from a spring receiving part and an engaging part with which a tool to rotate the adjuster part is to be engaged, and the engaging part includes a first engaging part formed by a gap between the plurality of vertical wall parts disposed separately from each other in a circumferential direction of the adjuster part and a second engaging part formed by a hole penetrating the vertical wall part.

A device for the height adjustment of a road vehicle interposed between a frame and a suspension of the road vehicle so as to allow the vehicle to shift from a road configuration to a race configuration and vice versa. The device comprises a base body provided with a first end, which can mechanically be connected to the frame of the road vehicle; a first mass, which can be connected to the base body so as to be movable along a sliding axis; a second mass, which is connected to the first mass so as to be movable along the sliding axis as well and is configured to be able to be connected to a suspension of the road vehicle and to change the stroke of the suspension depending on the position of the second movable mass.

A low suspension arm strut coupling is provided for a suspension of an off-road vehicle. The suspension comprises a lower suspension arm that is hingedly coupled between a chassis of the off-road vehicle and a spindle assembly that is coupled with a front wheel. An upper suspension arm is hingedly coupled between the chassis and the spindle assembly. A strut is coupled between the lower suspension arm and the chassis. A lower pivot couples the strut to the lower suspension, and an upper pivot couples the strut to the chassis. The upper and lower pivots provide a lower center of gravity of the off-road vehicle and a relatively smaller shock angle. The lower suspension arm is reinforced to withstand forces due to movement of the front wheel and operation of the strut in response to travel over terrain.

A universal axle-hub assembly is provided for an off-road vehicle. The universal axle-hub assembly comprises a wheel hub that receives a constant velocity (CV) axle snout into an opening extending through an axle support of the wheel hub. An outboard-most portion of the opening is a splined portion that engages with similar splines disposed on an outboard-most portion of the CV axle snout. An inboard-most portion of the opening is a smooth portion that receives a smooth portion of the CV axle snout. The axle support extends through an entirety of the width of a bearing that supports the wheel hub, such that the bearing supports the smooth portion of the CV axle snout and substantially eliminates shear forces acting on the splined portion of the CV axle snout. A bearing carrier supports the bearing and may be fastened onto a trailing arm or a spindle of the off-road vehicle.

A damper system for changing a ground clearance of a vehicle, including a main damper having a main damper chamber and a main damper piston movably arranged in a main damper tube and a spring assembly. The spring assembly includes a spring, a lower spring seat, and an upper spring seat. The spring is arranged between the lower spring seat and the upper spring seat, wherein one of the lower spring seat and the upper spring seat includes a cylinder and a piston, and the other one of the lower spring seat and the upper spring seat is coupled to the main damper and movable with the spring. The piston of the spring assembly is steplessly adjustable between a first position and a second position, wherein the first position corresponds to a predefined minimum ground clearance and the second position corresponds to a predefined maximum ground clearance.

A wrench and nut combination, including: a wrench lug including: a wrench lug feature that substantially mates with a nut feature of a nut of a shock absorber during a first rotation of said nut, relative to external body threads on a body of the shock absorber, in a first direction, wherein the wrench lug feature and the nut feature release during a second rotation of said nut, relative to the external body threads, in a second direction, wherein at least one of the first rotation and the second rotation causes an adjustment to a compressive coil spring pre-load of a set of coil springs disposed in the shock absorber.

A pressure buffer stop for a vibration damper that comprises for being at least partially received in a dome bearing housing an outer contour and for coaxial arrangement on a piston rod of the vibration damper a hollow-cylindrical basic structure with an inner contour, wherein the outer contour of the pressure buffer stop comprises in at least one region for being at least partially received in the dome bearing housing a three-dimensionally structured surface.
