Abstract
The invention discloses a rubber shock absorber. The shock absorber comprises a mandrel, an upper axial elastic body, a lower axial elastic body, a radial shock absorbing pad and an assembly body; the upper axial elastic body and the lower axial elastic body are arranged on the mandrel in a sleeving mode, the shock absorbing pad and the assembly body which are matched with each other are arranged between the upper axial elastic body and the lower axial elastic body, the upper end of the upper axial elastic body and the lower end of the lower axial elastic body are provided with an upper gasket and a lower gasket respectively, the upper gasket and the lower gasket are arranged on the mandrel in a sleeving mode, a square-head bolt connected with the mandrel is arranged on the top of the upper gasket, and a locknut connected with the mandrel is arranged on the bottom of the lower gasket. The shock absorber solves the problems that a traditional top plate shock absorber is poor in shock absorbing and noise reducing effect, low in structural reliability and short in service life.
Description
Technical field
The invention belongs to rubber damper, be specifically related to the rail traffic vehicles top board shock absorbers such as a kind of high speed train, subway.
Background technology
Along with the raising speed by a large scale of railway, passenger requires more and more higher for ride quality, and shock absorber, as the critical elements of rolling stock, has played vital function in the safety keeping railway vehicle to run and the traveling comfort taken.
Existing automobile-used rubber damper existing problems: 1. effectiveness in vibration suppression is poor, and especially the noise in VIP region and pantograph region is comparatively large, and train traveling comfort is poor; 2. structural reliability is low, rubber and metal piece bonding part easy to crack, shock absorber is shorter for service life.
Summary of the invention
In order to overcome the problems referred to above that prior art field exists, the object of the invention is to, a kind of rubber damper is provided, solving the problems such as traditional rubber damper effect of vibration and noise reduction is poor, structural reliability is low, the life-span is short.
Rubber damper provided by the invention, it comprises mandrel, upper axial elasticity body, lower axial elastic body, shock pad, assembly, described upper axial elasticity body and lower axial elastic body are set with on mandrel, the shock pad, the assembly that cooperatively interact is provided with between upper axial elasticity body, lower axial elastic body, described upper axial elasticity body upper end, lower axial elastic body lower end are respectively equipped with the Upper gasket be set on mandrel, lower gasket, the top of described Upper gasket is provided with the bolt be connected with mandrel, and the bottom of lower gasket is provided with the black nut be connected with mandrel.Described upper axial elasticity body, the elastomeric middle sulfuration of lower axis embed one deck skeleton, and described upper axial elasticity body, the elastomeric upper surface of lower axis and lower surface are equipped with decorative pattern.
Upper axial elasticity body, lower axial elastic body are made by polysulphide rubbers, and middle sulfuration embeds one deck skeleton, and the material of this skeleton is fiber or metallic material, and upper axial elasticity body, the elastomeric upper surface of lower axis, lower surface are equipped with decorative pattern; Radial vibration-reducing pad is made by the material such as polysulphide rubbers or nylon, and Intermediate Gray circular hole is used for coordinating with mandrel, and periphery coordinates with assembly.
Upper and lower axial elasticity body upper and lower surface is with decorative pattern, and lay can be parallel or angled, by adjustment precompressed amount size, can obtain higher damping coefficient and required rigidity in wider temperature and frequency limit.
Rubber damper provided by the invention, its beneficial effect is, this mount pad structure is simple, compact; Effective minimizing is delivered to the vibration in car, reduces noise in compartment; Axial elasticity body and metal piece adopt Split type structure, reasonable stress, and load-carrying capacity is strong, improves durability of product; Adjustment precompressed amount makes variable rigidity, can meet the requirement of the different elastic behavior of different directions.
