Concave and convex spline type tubular rubber shock absorber with interval expansion variable layer

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-duty machinery using diesel engines has relatively harsh operating conditions, with prominent low-frequency vibration and greater harm. The rubber shock absorber with ordinary tubular structure has relatively limited radial and circumferential deformation of the rubber, low damping loss factor, and poor damping effect, which limits its scope of use. Summary of the invention

[0003] In order to solve the problems of low damping loss factor and general damping effect of the existing ordinary tubular rubber shock absorber structure, the present invention provides a concave-convex spline type tubular rubber shock absorber structure with an interval expansion layer to improve the vibration reduction The structural damping loss factor of the device improves the damp...
