A damper for a telescopic fork leg for a front fork of a vehicle, wherein the damper comprises a twin-tube cylinder and a piston rod assembly comprising a piston rod, wherein a first piston is attached to the inner end portion of the piston rod, wherein a second piston is attached to the piston rod between the first piston and an outer end portion of the piston rod, wherein the inner tube is provided with at least one outlet hole 19 through the wall of the inner tube, the outlet hole being positioned such that a sealing portion of the second piston at compression of the damper travels past at the at least one outlet hole, and wherein the inner tube is provided with at least one return hole through the wall of the inner tube, the at least one return hole being positioned such that it connects a chamber of the twin-tube cylinder to an outer volume of the cylinder.

A plate spring member having a compressive residual stress distribution its which a compressive residual stress of at least part of a portion having a depth from a surface within 50 μm is 500 MPa or more, and the compressive residual stress of a portion having a depth from the surface exceeding 50 μm is less than 500 MPa.

A new type of independently damping pendulum suspension for pendulum dampers for use in tall slender constructions and technical installations, more particularly used in wind turbines. A Cardan joint is equipped with damping elements and mounted at the other end opposite the pendulum mass. The Cardan joint is able, despite the small motions, to sufficiently damp the oscillations of the pendulum produced by disturbing frequencies.

A vehicle seat assembly includes a seat frame, a seat pan, and a plurality of vibration isolators interposed between the seat frame and the seat pan for limiting transmission of vibrations from the seat frame to the seat pan.

A closure package for a vibration damper may include a base body that is connectable to a damper tube and comprises a first end and a second end. The first end forms an end side of the damper tube and the second end is disposed in the damper tube. A seal for sealing a piston rod may be disposed in the base body. A seal holder may be disposed between the seal and the base body at the first end. The seal holder for axially fixing the seal may be connected to the base body in a form-fitting and/or force-fitting manner. The seal holder may be fusible in an emergency. For releasing the connection to the base body, the seal holder may be thermoplastically deformable upon overheating of the vibration damper.

A conical spring washer includes a symmetrical annular body, a plurality of inner tabs and a plurality of outer tabs formed in the body. Each of the plurality of inner tabs has a width that tapers radially inwardly. Each of the plurality of outer tabs has a maximum width that is greater than a maximum width of each of the plurality of inner tabs. An intermediate portion is defined in the body and disposed between the plurality of inner tabs and plurality of outer tabs. The plurality of inner tabs and plurality of outer tabs are flexibly coupled to the intermediate portion.

An air spring provided by the present application comprises a top plate, a diaphragm, a first rubber metal spring and a second rubber metal spring; the diaphragm is arranged between the top plate and the first rubber metal spring; the first rubber metal spring is hollow to form a cavity, and the cavity of the first rubber metal spring penetrates through a top of the first rubber metal spring in a vertical direction, and the top of the first rubber metal spring is connected to a first support, and a top of the first support corresponds to the top plate to come into contact with the top plate when the diaphragm is out of air; the second rubber metal spring is fixedly inserted in the cavity of the first rubber metal spring; a top of the second rubber metal spring is connected to a second support, and a top of the second support corresponds to the top plate to come into contact with the top plate when the diaphragm is out of air; and, when the diaphragm is inflated, there is a height difference h between the top of the second support and the top of the first support, where the h0. The air spring provided by the present application can ensure ride comfort of the vehicle under a low-load condition and avoid damage to other components resulted from a subsidence of a vehicle body under a heavy-load condition.

A first shock isolator is provided that includes an axial compression element, a first disc spring, a disc spring system, and an annular stand-off. The first disc spring has a non-linear load-deflection response. The disc spring system is configured to be deflected by the first disc spring and has a linear load-deflection response. A second shock isolator is provided that includes an axial compression element, first and second disc springs and corresponding first and second annular stand-offs. The first and second disc springs have non-linear load-deflection responses. The first and second annular stand-offs hold the first disc and second disc springs in a spaced apart parallel configuration. The second disc spring is configured to be deflected by the first disc spring. The first and second shock isolators exhibit first and second combined load-deflection curves that include a constant load region.

A dampener for an exit device may be disposed between a portion of an exit device actuator and an exit device chassis so that the dampener dampens vibrations to reduce noise of the exit device and/or inhibit unintentional movement of the actuator to an actuated position. The dampener may be composed at least partially of a viscoelastic material.

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.
