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 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.

An outdoor power equipment unit includes independent suspension system having a frame, a first wheel assembly, a second wheel assembly, a first laterally-extending suspension arm pair, and a second laterally-extending suspension arm pair. The first wheel assembly includes a first wheel and a first side suspension arm. The first side suspension arm is pivotably coupled at a first end to a first side structural member and is fixedly coupled at a second opposite end to a joint of the first wheel assembly. The second wheel assembly is arranged similarly to the first wheel assembly. Both the first laterally-extending suspension arm pair and the second laterally-extending suspension arm pair are configured to independently pivot about the frame to be vertically displaceable relative to the frame.

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 method and apparatus for a suspension comprising a spring having a threaded member at a first end for providing axial movement to the spring as the spring is rotated and the threaded member moves relative to a second component. In one embodiment, the system includes a damper for metering fluid through a piston and a rotatable spring member coaxially disposed around the damper and rotatable relative to the damper.

A shock absorber includes a cylinder which is a conductor; a rod inserted into the cylinder from one end side of the cylinder, a suspension spring arranged outside the cylinder, a spring receiver which receives a load of the suspension spring on the one end side of the rod, and a protective member arranged on the one end side of the rod and configured to protect the rod. The protective member has a coil configured to detect a relative position between the cylinder and the protective member, and an end portion formed on the one end side of the protective member is arranged so as not to receive a load from the spring receiver.

A rotational adjustment device comprising: a handle; a gripping apparatus connected to and extending from the handle; a rachet assembly located within the gripping apparatus and configured to rotate a portion of the gripping apparatus; a pivot apparatus configured to allow movement of the gripping apparatus between an open position and a closed position so that when in the open position, the gripping apparatus is extendable around a feature of interest; and a locking apparatus that releasably locks the gripping apparatus in the closed position.

A suspension thrust assembly, the suspension thrust assembly including a damping component and a rigid component, the damping component being overmolded and formed to the rigid component; the damping component including a damping radial portion; the rigid component including a rigid radial portion; where a ring-shaped damping component protrusion is provided on the damping radial portion, a ring-shaped rigid component groove is provided on the rigid radial portion, and the damping component protrusion is fitted in the rigid component groove.

An assembly includes a spring seat, a spring seat insert, and a seal. The spring seat is slidable along the spring seat insert to define an expandable fluid chamber therebetween. The spring seat includes a groove defining a mating surface. The seal is between the spring seat and the spring seat insert. The seal includes a mating portion at the first end engageable with the mating surface of the groove to prevent fluid from exiting the fluid chamber.
