Abstract
The utility model relates to an axially symmetrical precompression rubber joint, which comprises a metal jacket and a vulcanization body, wherein the vulcanization body consists of a central spindle, an elastic rubber body, a left spacer bush and a right spacer bush which are vulcanized, wherein a certain taper angle alpha is formed between the elastic rubber body and the center line of the center spindle, the taper angle alpha is generally 15-25 degrees, the left spacer bush and the right spacer bush of the vulcanization body and the elastic rubber body are respectively and symmetrically distributed along the axial central line, a section of H-shaped gap is formed between the left spacer bush and the right spacer bush of the vulcanization body, and the vulcanization body is in interference fit in the jacket, and wraps the flanges of the two ends of the jacket to enable the left spacer and the right spacer bush to be closed so as to form a whole product. The ratio of rigidity of the radial direction and rigidity of the axle direction of the rubber joint can reach about 2:1, and even 1:1, and the service life of the rubber joint can be improved.
Description
Technical field
The utility model relates to a kind of elastic damping element, is meant a kind of axially symmetric precompressed rubber joint especially.
Technical background
Rubber arthrosis class elastic element is the compound damping element of using always of a kind of rubber-metal, can be widely used in various vibration dampings, elastic joint part position, plays the effect of vibration and noise reducing, especially uses very general in the bogie of rolling stock.In order to improve the working life of rubber arthrosis, generally all can allow rubber elastomer that certain precompression is arranged, and provide pretightening force to rubber elastomer at present mainly is by the extruded product external diameter, this method has its advantage, but its deficiency is arranged also, owing to be subjected to the restriction of bulk and structure, rubber arthrosis footpath/axle ratio of rigidity minimum by the extruded product external diameter also can only reach 5: 1, and at present a lot of rubber arthrosis are in order to satisfy the dynamics of vehicle performance requirement, need footpath/axle ratio of rigidity to reach 2: 1, or even 1: 1, this requirement can not realize substantially by the extruded product external diameter.
Summary of the invention
The purpose of this utility model is to provide a kind of novel axially symmetric precompressed rubber joint, and its footpath, axial rigidity ratio can reach about 2: 1.
Technology implementation scheme of the present utility model is: a kind of axially symmetric precompressed rubber joint, form by metal-coating and sulfuration body, wherein said sulfuration body is to be sulfided by mandrel, elastic rubbery body and left and right spacer to constitute, and elastic rubbery body and mandrel center line have certain conicity angles alpha, and conicity angles alpha is generally 15 °～25 °; And sulfuration left and right spacer of body and elastic rubbery body respectively vertically center line be symmetrically distributed, the left and right spacer of sulfuration body one section H shape gap arranged each other.And the sulfuration body is to go into overcoat by interference press-fit, and left and right spacer is closed up overcoat two ends flange parcel, constitutes an integral product.
The utility model has certain conicity angles alpha because of elastic rubbery body and mandrel center line, after left and right spacer is drawn close, elastic rubbery body produces precompression, by adjust conicity angles alpha, H shape gap can realize the expection pre compressed magnitude of elastic rubbery body and radially, the axial rigidity ratio.Conicity angles alpha is generally 15 °～25 °.This structure footpath, axial rigidity ratio can reach about 2: 1, or even 1: 1, the working life of having improved rubber arthrosis.
