A device (10) for protecting a mechanical part (20) against damage, in particular corrosion. The mechanical part bears on a support (22), or is under pressure as a result of weight. A flexible area (12) is designed to be in direct contact with the mechanical part and at least one row of rectilinear pads (14) designed to be in direct contact with the support. The row includes a plurality of pads (14-1, 14-2, 14-3) rigidly connected to the flexible area. The pads are more rigid than the flexible area, and are preferably rectangular in shape.

A shock absorber has a first and second end surfaces opposite to each other in an axial direction, and a plurality of connection surfaces. The first end surface is an N-sided polygon (N is an integer of 3 or more and the second end surface is an M-sided polygon (M is an integer of 4 or more and more than N). (M−N) vertices are provided at intermediate positions in the axial direction on a circumferential surface defined by the plurality of connection surfaces. From the vertices, one first ridgeline reaches one vertex of the first end surface and two second ridgelines reach a corresponding one of two vertices of the second end surface. The remaining vertices are connected to each other by (2×N−M) third ridgelines. The first ridgeline, the second ridgelines, and the third ridgelines define the plurality of connection surfaces.

Embodiments described herein relate generally to apparatus with ribbed structures or geometries for stiffness and damping control, and methods of producing the same. In some embodiments, an apparatus includes a ribbed structure having a set of ribs, configured to deform elastically under shock. In some embodiments, the set of ribs can have a sinusoidal wave shape. In some embodiments, the set of ribs can have a heterogeneous wave shape. In some embodiments, the set of ribs can have material properties that change along the length of the ribbed structure, such as wavelength, amplitude, wave shape, and material thickness.

Energy dissipation pads are described herein. In one aspect, a system can include an airdrop load; and at least one energy-dissipation assembly having a grid formed from a plurality of boards each including a plurality of slots sufficient to accommodate a thickness of others of the plurality of boards and form a plurality of joints; where at least one of the at least one energy-dissipation assemblies is positioned below or within the airdrop load such that the grid of the energy-dissipation assembly is at least partially perpendicular to an anticipated impact vector.

A suspension component (730), including: an elastomeric component top member (832); an elastomeric component bottom member (830); and a plurality of elastomeric zig-zag columnar elements (800). The elastomeric zig-zag columnar elements connect the elastomeric component top member to the elastomeric component bottom member and are separated from each other by a gap (806).

An elastic link comprising a first sleeve and a second sleeve. The first sleeve comprises a first elastic body, a first inner armature surrounded by the first elastic body, and a first outer armature surrounding the first elastic body. The second sleeve comprises a second elastic body, a second inner armature surrounded by the second elastic body, and a second outer armature surrounding the second elastic body. The first elastic body and the second elastic body presenting different elastic behaviors. This constitutes an improved elastic link.

A cab mount (1A) includes an upper mount elastic body (2) and a lower mount elastic body (3) that are configured to sandwich a frame (10) of a vehicle. The upper mount elastic body (2) has recesses (4) in an inner peripheral surface (f21) of the upper mount elastic body (2). The recesses (4) extend in a circumferential direction. Each of the recesses (4) has an upper contact surface (f1) and a lower contact surface (f2) that are in contact with each other in a steady state.

A damper unit for use in a vibration-reducing assembly for a steering wheel is disclosed. The damper unit includes a slider configured, upon horn activation, to slide on a guide shaft. A damper element made from an elastomeric material is arranged on a first part of the slider. A molded horn spring element is molded directly on a second part of the slider and is configured to exert a spring force on the slider. The damper unit provides a unitary structure providing both a vibration damping function and a horn spring function in one single assembly unit, reducing the number of components to assemble. A vibration-reducing damper assembly including one or more such damper units is also disclosed, as well as a method of making such a damper unit.

A bracket-equipped vibration-damping device including: a vibration-damping device main body including vertically-separated, elastically-connected first and second mounting members; a bracket receiving the device main body inserted laterally thereinto; a connection-insert section provided for the second mounting member; a connection groove provided for the bracket extending in an insertion direction of the device main body; at least one up-down urging rubber fixed on an outer surface of the connection-insert section on an upper-lower first side; and a lock protrusion formed on an inner surface of the connection groove on an upper-lower second side, with a smaller protrusion dimension than an up-down thickness of the up-down urging rubber such that the connection-insert section is laterally inserted into the connection groove beyond the lock protrusion before being urged to the second side by the up-down urging rubber to be positioned to the connection groove.

A lift arrangement of a lift truck, especially a forklift truck, has a lift mast defining a z-axis. The lift mast includes a first mast section and a second mast section. Damping elements made from elastic material are provided on the first mast section and/or the second mast section preventing a hard impact of the second mast section with the first mast section at the run-in end position of the second mast section. The damping elements are configured and arranged in such a manner that, in addition to damping the movement of the second mast section in the direction of the z-axis, the damping elements damp movements of the second mast section in the directions of the x-axis and the y-axis running perpendicularly to the z-axis.
