An additional spring for a shock absorber of a motor vehicle and a damper bearing for a shock absorber of a motor vehicle. In this case, the additional spring includes a first spring body which has a central hole for guiding through a piston rod of the shock absorber. The first spring body is formed spherical on an end face. The damper bearing according to the invention comprises a cylindrical receptacle space in which the first spring body of the additional spring is retained at least in certain regions, and is distinguished in that the receptacle space has a spherically formed base surface formed corresponding to the end face of the first spring body.

A linear damper includes a rack, a carriage, a gear assembly, and a spring. The rack includes a connector. The carriage is slidably engaged with the rack. The gear assembly is between the carriage and the rack. The spring is secured to the rack to selectively urge the carriage away from the connector.

A tail skid shock absorber including an outer shock absorber canister, a crushable indicator cartridge disposed within the outer shock absorber canister, and an indicator rod coupled to the crushable indicator cartridge so as to move with a portion of the crushable indicator cartridge as a unit.

Provided herein is a jounce bumper (18) for mounting in a vehicle suspension system (2) comprising a shock absorber (6), the jounce bumper (18) having a central bore (20) extending in an axial direction (A). The jounce bumper (18) comprises an elastically compressible bumper portion (24) comprising a plurality of convolutes stacked in an axial direction (A) of the jounce bumper (18), each convolute comprising a crest (26) and a root (28). A cross-section of the compressible portion (24) perpendicular to the axial direction (A) is non-circular, the non-circular shape being configured to provide a variable compression resistance in relation to an axial compression displacement (Cd) of the jounce bumper (18).

A high tension coil spring structure for a bed mattress includes spring bodies and exposed wiring portions which absorb an external load. Diameter-increasing portions (A) are formed on at least one of upper and/or lower end wiring portions (14, 14) of body wiring portions (12), and provide spaces in which upper and/or lower exposure start wiring portions (16-5, 16-5) move upward and downward. Rigid support ends (18) are formed on at least one of the body wiring portions (12) and upper and lower exposed wiring portions (16, 16), and absorb a compressive load. The diameter-increasing portions and the rigid ends of the coil spring structure fundamentally prevent noise caused by friction between the exposed wiring portions and surrounding wiring portions when the exposed wiring portions are compressed and significantly increase the elasticity of the exposed wiring portions.

A damper assembly for a bicycle wheel assembly may include a first damper configured to be disposed about a hub assembly of the bicycle wheel assembly. The first damper is configured to apply a damping force against a spoke segment of at least one spoke of a plurality of spokes of the bicycle wheel assembly. The first damper includes a first end applying the damping force against the spoke segment.

A control arrangement for a frequency-dependent damping valve having a control pot and an axaially displaceable control piston that axially limits a control space in the control pot and is connected to the damping valve device via an inlet connection. A spring element is arranged between the control piston and the damping valve that introduces a spring force axially into the control piston and the damping valve. When the control piston displaces towards the damping valve and the spring element increases the pressing pressure of the valve disks to increase the damping force. An axial position of a stop in the control arrangement is adjusted by plastic deformation of the pot base. A deformation portion produced by the plastic deformation and a depression partially receives the guide bush. A cross section of the depression corresponds to an outer cross section of the guide bush received in the depression.

A damper includes a top board mounted in a chamber of an elastic rubber sleeve to shield an assembly port of the elastic rubber sleeve, at least one first elastic pad disposed in the chamber of the elastic rubber sleeve, and a compression spring disposed between the first elastic pad and the top board. The compression spring provides a more reliable action stroke to completely absorb the external impact or vibration energy. More particularly, when the external impact or vibration force disappears, the energy stored by the compression spring can quickly recover the elastic rubber sleeve, and effectively enhance a vibration absorption effect and a response speed of the overall damper.

A spring damper device comprising a directional spring (e.g., coil) having first and second ends, and defining an inner diameter region. A damper (e.g., viscoelastic polymer slug) comprising an element of elasticity configured to be situated within the inner diameter region of the directional spring. In response to a load on the spring damper device, the directional spring operates to compress, and the damper operates to dampen vibration associated with the load. The damper can comprise a viscoelastic damper comprising both an element of viscosity and the element of elasticity. The damper can be substantially coaxially aligned with the directional spring. Spring damper device(s) can be preloaded in a micro adjustment mechanism to account for positional adjustments between two structures (e.g., between a scope and a firearm), such that the spring(s) attenuate a shock impulse event (e.g., when firing), while the damper(s) attenuate vibration (e.g., to prevent damage the scope).

An axle box suspension includes: an axle beam including an axle beam main body portion extending from the axle box in a car longitudinal direction and a pin portion projecting from a tip end of the axle beam main body portion in the car longitudinal direction; a tubular elastic bushing including an inner tube portion, an outer tube portion, and an elastic portion interposed between the inner tube portion and the outer tube portion, the inner tube portion being fitted to the pin portion; an adapter attached to the outer tube portion and coupling the axle beam and the bogie frame; and a first stopper attached to the pin portion and configured to, when the axle box is displaced relative to the bogie frame toward one side in the car longitudinal direction by a predetermined distance, contact the adapter to restrict displacement of the axle box.
