An air suspension strut for a motor vehicle, comprising an air spring having a shock, wherein the air spring comprises an air spring cover and a rolling piston, wherein a rolling bellows of elastomer material is clamped in an airtight manner between the air spring cover and the rolling piston, wherein the rolling bellows, together with the air spring cover and the rolling piston, delimit a working chamber filled with compressed air, wherein the shock damper is supported via a damper bearing arranged on a piston rod in a pot-shaped bearing holder of the air spring cover. The closure cap seal comprises an inner sleeve and a closure part radially enclosing the inner sleeve, wherein the inner sleeve is pushed onto an end section of the piston rod, and the closure part is pushed sealingly into the bearing holder.

A bearing arrangement for a damper bearing of a shock absorber in a wheelhouse of a vehicle. A damper receptacle is formed in a wheelhouse sheet metal part delimiting the wheelhouse. A threaded bolt is guided through a damper bearing screw hole and through a screw hole of the damper receptacle and the bolt tip of the threaded bolt is screwed together with an internal thread of a reinforcement element which is arranged on the side of the damper receptacle. A positioning aid is associated with the damper receptacle, via which positioning aid the damper bearing of the shock absorber can be pre-positioned in an assembly process up to an installation position in which the screw hole of the damper bearing, the screw hole of the damper receptacle, and the reinforcement element internal thread are oriented flush with respect to each other in a screw direction.

The present disclosure discloses a nonlinear spring connection structure and a motor. The nonlinear spring connection structure includes a stator, a mover and an elastic connector provided between the stator and the mover. The elastic connector includes a first end connected with the stator, a second end connected with the mover and at least two transition-connecting portions connected between the first end and the second end. The at least two transition-connecting portions extend from the first end towards the second end with sequentially decreasing sizes. An elastic connector is provided between a stator and a mover. In practice, the elastic connector, through deformation of itself, provides a restoring force for the mover during movement, so that the mover can perform a linear movement relative to the stator. In this way, a nonlinear spring connection structure is simpler and manufacturing cost of the nonlinear spring connection structure is reduced.

This shock absorber includes an outer cylinder, and a bracket having a pair of extension parts. The outer cylinder has an opening and into which the inner cylinder is inserted and fixed. The pair of extension parts extend outward in a radial direction of the outer cylinder from different positions spaced apart in a circumferential direction of the outer cylinder. A hole portion and a reduced-rigidity part are provided in the pair of extension parts. The hole portion is provided at a position facing an attachment hole of an attachment member disposed between the pair of extension parts. The reduced-rigidity part is disposed at a disposition position on the outer cylinder side of the hole portion at the same position as the hole portion in the axial direction of the outer cylinder. The reduced-rigidity part has a lower rigidity than a position different from the disposition position.

The present disclosure provides a method of manufacturing a damper for a vehicle. The method includes forming a groove on an outer surface of a first component in a first annular region. The first component is tubular. The method further includes inducing a compressive residual stress in a second annular region. The second annular region is at least partially aligned with the first annular region along a longitudinal axis of the first component. The method further includes coupling a second component to the first component. Surfaces of the first component and the second component directly engage one another at an interface. The second component is axially aligned with and radially surrounding at least a portion of the first annular region. In some configurations, forming the groove and inducing the compressive residual stress are performed concurrently, such as by low plasticity burnishing.

A bump stop assembly for a UTV with a frame attachment, a shock absorber attachment, two panels, a shock absorber and a bracket. The frame attachment is coupled to the frame of the UTV and the shock absorber attachment is coupled to the shock absorber. The two panels extend between the frame attachment and the shock attachment. The bracket is coupled to the trailing arm of the suspension system of the UTV. The bump plate bracket has a bump plate located to contact the shock absorber when a force applied to the suspension system causes the suspension system to reach a predetermined level of a capacity of the suspension system to absorb. The bump plate transfers a portion of the force applied to the shock absorber. The shock absorber is configured to absorb energy transferred to the bump stop assembly by the force applied to the suspension system.
