Stop washer for an elastomeric bearing, elastomeric bearing and subframe for a vehicle
A stop washer for an elastomeric bearing is manufactured as a single unit from a sheet metal blank and furnished with a surface protection. In addition to its function as a path limiter, it has at least one of the following functions by a structure integrated into the forming process of the sheet metal blank, namely the function of a thread and/or anti-rotation protection. Furthermore, an elastomeric bearing with such a stop washer and a subframe equipped therewith are conceivable.
Mount bushing with integrated isolated outer insert for enhanced high frequency isolation performance
A mount bushing includes an outer mounting ring adapted for connection to a mount structure. An outer structural ring is disposed inside of the outer mounting ring. A main elastomeric isolation arrangement is disposed between the outer structural ring and an inner structural insert, wherein the main elastomeric isolation arrangement is supported between the outer structural ring and the inner structural insert by elastomer material. An outer ring isolation layer of elastomer is disposed between the outer mounting ring and the outer structural ring, wherein the outer ring isolation layer is isolated from the main elastomeric isolation arrangement by the outer structural ring. A mounting bolt is inserted through a bore in the inner structural insert.
TORSION SPRING DEVICE, BEARING, AND VIBRATION DAMPER
Torsion spring device includes an outer housing, an inner housing located in the outer housing, and an elastic element. The elastic element supports the inner housing relative to the outer housing such that a restoring force is built up between the outer housing and the inner housing as a result of a deflection caused when the outer housing and the inner housing are rotated relative to one another. The restoring force-deflection curve can be adjusted by a choice of shape and/or material of the outer housing, of the inner housing, and of the elastic element and/or wherein the hysteresis can be adjusted by a choice of shape and/or material of the outer housing, of the inner housing and of the elastic element.
AUTOMATED DECOUPLING SHOCK ISOLATION FOR VIBRATION COUPLERS
A shock isolator is arranged between two automated coupler parts in a vibration testing unit. When the coupler parts are engaged and coupled during vibration testing of a component, the shock isolator is disabled, and when the coupler parts are disengaged and decoupled after vibration testing, the shock isolator is activated to absorb excess shock energy and prevent shock transfer between the coupler parts that would damage the test component. The shock isolator includes a bushing that is inserted in a lower part of the two automated coupler parts and a compressive fit rod that is press-fit into the bushing. The bushing has a chamfered volume and the compressive fit rod has a corresponding compressible volume that is displaced into the chamfered volume to disable the shock isolator. After vibration testing, the compressive fit rod is expandable to a regular shape to activate the shock isolator.
Spray boom for an agricultural machine
The present invention is directed to a spray boom for an agricultural machine in which the boom is arranged as a truss with interior diagonal struts of the truss being configured to absorb tension and compression energy imparted by deflections over the length of the boom with such energy being dissipated as heat. In one aspect, the diagonal strut could comprise a rod moveable with respect to a tube with a polymer, such as an elastomeric material, arranged in the tube to dampen the movement. The tension and compression of the diagonal strut could subject the dampener to a shearing force which could be absorbed by the dampener rather than transferred to the machine.
Bushing with wear pad retainer
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.
ANTI-VIBRATION MOUNT AND VEHICLE COMPRISING SUCH AN ANTI-VIBRATION MOUNT
Anti-vibration mount comprising a first frame, a second frame, an elastomeric main body connecting the first frame and the second frame, the elastomeric main body allowing relative displacements of the second frame relative to the first frame in a first direction of vibration and in a second direction of vibration perpendicular to the first direction of vibration, the elastomeric main body also being suitable for mounting a weight in the first direction of vibration. An inertia body is connected to the first frame by an elastic suspension interposed between the inertia body and the first frame along the second direction of vibration. An elastomeric lateral abutment body is interposed between the first frame and the inertia body to limit the relative displacements of the second frame with respect to the first frame in the second direction of vibration. The inertia body has a natural frequency lower than 800 Hz.
