A modular suspension buffer for vehicle has customizable hardness and height to provide various combinations of initial contact softness and non-linearly increasing resistance during compression so as to improve driving stability, loading capacity, off road performance, and/or ride comfort while extending the operational lifespan of the vehicle suspension system.

A modular suspension buffer for a vehicle having customizable hardness and height to provide various combinations of initial contact softness and non-linearly increasing resistance during compression so as to improve driving stability, loading capacity, off road performance, and/or ride comfort while extending the operational lifespan of the vehicle suspension system. Specifically, a universal modular coil spring buffer having a plurality of modules arranged in different configurations adaptable to be inserted in the gap of a coil spring of a vehicle to prevent shocks. The different configurations of a primary module and a plurality of secondary modules can be employed for different vehicles with different coil spring dimensions and based on the distance between the adjacent coils. The buffer lessens the compression to the coil spring thereby minimizing oil leaks caused from the shocks.

Described herein is an axle assembly and method of fabrication thereof. The axle assembly includes an axle having a first geometric shape housed within an axle housing having a second geometric shape. A shock absorber is located between the axle and the axle housing. The shock absorber supports the axle within the axle housing and comprises a first material and comprises a multi-sided configuration. The first geometric shape and the second geometric shape comprising polygons.

A variable stiffness spring assembly includes first and second members made of a first material and separated by a gap along at least a portion of their lengths, and one or more layers made of a second material disposed in the gap. The variable stiffness spring assembly can be incorporated into or take the form of a limb support assembly, such as a prosthetic foot. The second material disposed between the first and second members is rate-sensitive or speed-dependent, such that the material exhibits different properties when the user of the prosthetic foot is walking at high or fast walking speeds compared to low or slow walking speeds. The prosthetic foot can exhibit high damping and energy absorption, and therefore stability, at slow speeds, and high energy return at faster speeds.

A composite vibration-damping body including a first elastic body and a second elastic body overlapped with each other, wherein the first elastic body is formed of a material having higher attenuation than that of the second elastic body, the first elastic body includes a recessed part opening onto a surface of the first elastic body, and the recessed part forms a gap, and a strain concentration part configured to be subjected to an increased strain during load input is set to a wall of the gap of the of the first elastic body.

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 method for manufacturing a vibration isolation apparatus includes: molding elastic parts of an elastic body; compressing in which the elastic parts are pressed against positions in which the elastic parts are provided to an inner member so that the elastic parts are compressed to have a size equivalent to a size in which the elastic parts fit between the inner member and an outer cylinder; press-fitting the inner member and the elastic parts integrally into the outer cylinder while the elastic parts are kept compressed; and fastening the elastic parts to the inner member and the outer cylinder.

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.
