A coil spring jig includes a spring support portion where one end of a coil spring is capable of being placed, a plurality of displacement regulating portions extending along an axis of the coil spring from the spring support portion with the coil spring supported by the spring support portion as a reference, capable of abutting against an outer peripheral surface of the coil spring, and regulating displacement of the coil spring in a radial direction of the coil spring, and a lid portion supported by the displacement regulating portions and capable of keeping the coil spring in a compressed state by sandwiching the coil spring together with the spring support portion.

A spring element for an upper nipper of a combing machine has a first element with a through opening arranged transversely to a longitudinal axis. A second element has an internal thread for fastening a shaft adapter, and a guide opening with an opening width as well as a passage opening arranged in the longitudinal axis on a side of the guide opening facing away from the internal thread. A compression spring is arranged between the first and second elements. A connecting element is held in the bore of the first element and projects through the passage opening of the second element into the guide opening, the connecting element having a larger diameter than the passage opening on a side thereof opposite the first element. The first element has a tubular lug overlapping the compression spring, and the second element has a sleeve overlapping the compression spring and the lug.

A bushing is disclosed for pivotally mounting an end portion of an axle-supporting beam of a vehicle suspension system to a hanger bracket of the vehicle with a pair of wear pads positioned between sides of the end portion of the beam and the hanger bracket, where the pair of wear pads each has a central opening defined by an inner edge. The bushing includes a tubular body having a longitudinal axis, a first end portion, a second end portion and a beam support portion positioned between the first and second end portions. A first resilient wear pad retainer extends radially from the first end portion of the body and a second resilient wear pad retainer extends radially from the second end portion of the body. Each of the first and second wear pad retainers are configured to move into a deflected position when contacted by an inner edge of a wear pad central opening and to rebound back to an original position afterwards as the wear pad is positioned on the first or second end portions of the body so that the wear pad is secured to the bushing.

A damping force generation device for a vehicle includes a shock absorber including a cylinder and a piston. The shock absorber is coupled to a vehicle body, a wheel carrier, and the like at a rod part of the piston and the cylinder, respectively, and is configured to generate a damping force due to a flow resistance when oil passes through an orifice formed in the piston. Each of self-discharge type charge eliminators is fixed to a surface of a specific member being at least one of a component of the shock absorber or an auxiliary member connected to the component. The charge eliminator reduces positive electric charge that is charged to the specific member, to thereby reduce a charge amount of the oil.

A hybrid rotational passive energy absorber (100) is configured to mitigate effects of a load on an attached system. An axle (170) is anchored to a housing (110) at a first axle end and a second axle end. A free swinging weighted arm (180) includes a beam (130) having a length L, a pivot portion (185) disposed at a first end of the beam, and an internal mass (120) at a second end of the beam. A bearing (160) rotatably connects the pivot portion to the axle. The bearing is configured to provide smooth motion of the weighted arm around an axis (150) of the axle in a rotation and/or oscillation plane orthogonal to the axis.

A damper is disposed in at least one of a space between a supported member and a supporting element or a space between the supported member and a supporting member. The damper includes a cushioning member and a protecting member. The cushioning member is configured to relax stress applied to the supported member that is supported by the supporting member together with the supporting element. The cushioning member includes a facing portion that faces the supported member, an opposite portion that is opposite to the facing portion, and a side surface portion that is located between the facing portion and the opposite portion. The protecting member is disposed on the side surface portion to cover the cushioning member from an outside of the cushioning member.

The invention relates to a protective device for a shock absorber, in particular a commercial vehicle shock absorber, comprising a first base area and a second base area, wherein the first base area and the second base area are connected to one another in such a way that via a swivel axis they can be swiveled in relation to one another between an assembly state and an operating state, and wherein the first base area and the second base area in the operating state substantially form a hollow cylindrical shape.

A centrifugal pendulum damper in which a rolling mass can be lubricated by a simple structure without limiting vibration damping performance. The pendulum damper comprises: a rotary member; an inertia body arranged concentrically with the rotary member; a rolling mass held in a retainer on an outer circumference of the rotary member; a recess formed on an inner circumference of the inertia body; and a raceway surface formed on an inner circumference of the recess to which the rolling mass is contacted. In the centrifugal pendulum damper, oil remaining in the recess is discharged out of the recess through an oil passage.

A damper is disposed in at least one of a space between a supported member and a supporting element or a space between the supported member and a supporting member. The damper includes a cushioning member and a protecting member. The cushioning member is configured to relax stress applied to the supported member that is supported by the supporting member together with the supporting element. The cushioning member includes a facing portion that faces the supported member, an opposite portion that is opposite to the facing portion, and a side surface portion that is located between the facing portion and the opposite portion. The protecting member is disposed on the side surface portion to cover the cushioning member from an outside of the cushioning member.
