Embodiment

[0036] Inner spline grooves are processed on the inner surface of the outer ring of the shock absorber, and outer spline grooves are processed on the outer surface of the inner ring; the interval expansion layer is three equal-diameter 1 / 3 ring structure, through-holes are machined in the axial direction (according to specific production conditions, the interval expansion layer 4 can adopt a split structure: that is, along the arc-shaped connection of the centers of the cross-sections of these through-holes, the interval expansion layer 4 is divided into two layers, the inner and outer layers, which are stamped and formed separately, and then welded into a whole, which is convenient for processing and manufacturing and reduces costs); the rubber layer 2 mixes the compound rubber with an appropriate amount of metal particles and metal wires, and the metal wires are arranged as far as possible along the axial direction , The above parts are vulcanized and bonded to form a whole....

Abstract

The invention relates to a concave and convex spline type tubular rubber shock absorber with an interval expansion variable layer. The concave and convex spline type tubular rubber shock absorber comprises a spline type outer ring, a spline type inner ring, the interval expansion variable layer and a rubber layer; the interval expansion variable layer is arranged between the spline type outer ring and the spline type inner ring, and the spline type outer ring, the spline type inner ring and the interval expansion variable layer are both bonded with the rubber layer in a vulcanization manner; and evenly-distributed metal particles and metal wires are arranged in the rubber layer. The radial tension and compression deformation amount and the shear deformation amount are increased, the structural damping loss factors of the shock absorber are improved, the radial shock absorption effect of the shock absorber is improved, the heat dissipation effect of rubber is improved, and the service life of the rubber shock absorber is prolonged. The inner ring and the outer ring are both of spline type structure, the circumferential torsional deformation amount and the shearing deformation amount are increased, and therefore the structural damping loss factors of the shock absorber are improved, and the circumferential shock absorption effect of the shock absorber is improved.

Description

technical field [0001] The invention belongs to the technical field of shock absorbers, and in particular relates to a rubber shock absorber applied to a diesel engine suspension system. Background technique [0002] Heavy machinery using diesel engines has harsh operating conditions, prominent low-frequency vibrations, and relatively large hazards. For rubber shock absorbers with ordinary tubular structures, the radial deformation and circumferential deformation of the rubber are relatively limited, the damping loss factor is low, and the vibration reduction effect is not good, which limits its application range. Contents of the invention [0003] In order to solve the problems of low damping loss factor and general vibration reduction effect of the existing common tubular rubber shock absorber structure, the present invention provides a concave-convex spline tubular rubber shock absorber structure with interval expansion layer, in order to improve vibration reduction Th...
