A bearing provides a vibration-insulating mount on a first component with a hole through which a central longitudinal axis extends. The bearing includes a first bearing part with a first fixing structure that can be arranged on one side of the first component, and a second bearing part with a second fixing structure that can be arranged on the other side of the first component. In embodiments, the first fixing structure comprises first pins that can protrude into the hole, and the second fixing structure comprises second pins that can protrude into the hole. In embodiments, at least one of the pins of each fixing structure is biased or is able to be biased radially outwards with respect to the central longitudinal axis.

A clamp including: a holding portion configured to hold a wire harness; and a fixing portion that is provided in a portion of an outer circumferential surface of the holding portion and is to be fixed to a fixed portion; wherein the fixing portion includes: a base that includes a first surface that faces a holding portion side and a second surface located opposite to the first surface, a support shaft that extends from the second surface of the base in a direction away from the holding portion, a lock that is provided at a leading end of the support shaft and is formed to be able to be locked to the fixed portion, and a vibration suppressor that is made of a material whose elastic modulus is lower than that of the base and protrudes from the second surface of the base toward a lock side.

A drive assembly for a motor vehicle includes a drive, a transmission that can be driven by the drive, a drive housing, a transmission housing, and a fastening device. The drive is arranged in the drive housing, and the transmission is arranged in the transmission housing. The drive housing or the transmission housing can be fastened on a carrier by way of the fastening device. The fastening device includes a plurality of vibration dampers and sleeve elements. The sleeve elements surround the vibration dampers.

A negative stiffness shell has a convex first position, but can transition or snap to a concave second position under a force applied to the exterior surface of the shell in the convex first position. During the transition, the shell exhibits negative stiffness that permits a large amount of energy to be absorbed. The negative stiffness shell can withstand a high initial force threshold prior to transitioning. In the second, concave position the shell can still resist force. Moreover, it is possible for the shell to revert back to the first, convex position with minimal plastic deformation for subsequent use. The negative stiffness shells can be used collectively and/or in layers to increase the efficiency of the overall negative stiffness shell unit.

A vibration isolating bushing assembly may comprise a first T-bushing configured to receive a fastener, a second T-bushing configured to couple to the first T-bushing and the fastener, a first isolating washer, and a second isolating washer, wherein the first isolating washer and the second isolating washer are configured to couple between the first T-bushing and the second T-bushing.

A vibration absorber bush for an inner tube absorber for absorbing torsional and flexural vibrations, for the coaxial assembly in a hollow shaft which is penetrated by a central longitudinal axis includes at least one largely cylindrical first elastic element and a largely cylindrical second elastic element which are in each case disposed to be coaxial with the longitudinal axis and to be mutually adjacent in the radial direction. In embodiments, a reinforcement element is disposed between the elastic elements.

Disclosed is a method of suppressing vibration of a mechanical device imposing upon at least one human hand holding the mechanical device. The method generally includes steps of preparing and assembling a fixing pin, an upper metal pad, an upper suppressing pad, a lower suppressing pad, and a lower metal pad to form a vibration-suppressing unit, and employing a fixing rack in collocation with an actuating part to fix the vibration-suppressing unit onto a massage body. In particular, the two adjacent upper vibration-suppressing washers are specifically designed to have different elasticity modulus, and the two spaced away and not adjacent upper vibration-suppressing washers have the same elasticity modulus, thereby suppressing and alleviating the vibration level to hand due to counterforce. Thus, the method achieves the effect of suppressing vibration, greatly alleviates counterforce imposing upon hand, and effectively avoiding fatigue, sore, chronical inflammation, or physical hurt.

A leg assembly, and a shock absorption mechanism for a pole are provided. The shock absorption mechanism comprises a pole body and a leg assembly, wherein the leg assembly comprises a support leg, a tray surrounding the support leg, and a connecting sleeve for connecting the pole body inserting from the top of the support leg. When a bottom of the pole body is inserted into the connecting sleeve and tightly resists against the elastic limiting clamps, the elastic limiting clamps will be pushed outward and limited in the guiding slots of the support leg, so that the connecting sleeve with the pole body can move upward and downward relative to the support leg. There is a mounting space for the shock absorption spring between the support leg and the connecting sleeve, and the support leg has a trend of moving downward due to resistance from the shock absorption spring.

An impact mitigating assembly includes an elongate member formed from a plurality of triangulated cylindrical origami (TCO) unit cells that exhibit coupled rotational and axial motion. The unit cells include an end portion and a tubular member fixed to the end portion. The tubular member has a plurality of concave sides. Each side has a first triangular portion and a second triangular portion sharing an elastic connecting edge with the second triangular portion. The first triangular portion also shares an angled upright edge with the second triangular portion of an adjacent side. Compressing the tubular member longitudinally causes the connecting edge and the angled upright edge to elastically deform, for example by stretching, and causes the second end of the tubular member to rotate with respect to the first end of the tubular member.
