Automobile hanging arm yielding rubber assembly
The utility model relates to a kind of auto parts machinery, and what be specifically related to is a kind of improvement invention of automobile hanging arm yielding rubber assembly.
Automobile hanging arm yielding rubber assembly is installed on the automobile chassis, and its effect is to absorb the vibration that the road surface is transmitted, and relaxes and impacts.The automobile hanging arm yielding rubber assembly of prior art generally comprises lining, lining rubber and lining outer tube, lining rubber is located between lining and the lining outer tube, the position that the lining outer tube is connected with lining rubber is a square tube shape, the outer ring of lining rubber is square, so in use, lining rubber is under lining outer tube reaction force acts, in continuous impact and extrusion process, the rubber internal organizational structure changes easily, causes the damaged or fracture of gross distortion, rubber of rubber; Also have, the distortion of the lining rubber in the use is shunk, and does not have compressible cavity on the lining rubber of prior art, makes rubber produce very big internal stress like this, causes the change of rubber internal organizational structure, has shortened the working life of yielding rubber assembly.
[summary of the invention]
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of long service life, the saving automobile hanging arm yielding rubber assembly that the cost of material is low.
The utility model takes following technological scheme to finish: automobile hanging arm yielding rubber assembly, comprise lining, lining rubber and lining outer tube, lining rubber is located between lining and the lining outer tube, it is characterized in that: the position that described lining outer tube is connected with lining rubber is a tubular shape.Be provided with compressible cavity in the described lining rubber.
The utility model has changed the shape of lining outer tube and lining rubber outer ring, make the square circle that changes into of prior art, in the time of so just effectively disperseing lining rubber stressed to the active force of lining outer tube, just disperseed the reaction force of lining outer tube to lining rubber, improved the stressing conditions of lining rubber, improved the working life of lining rubber, thereby improved the working life of whole automobile hanging arm yielding rubber assembly; Also have, in lining rubber, be provided with rational compressible cavity, so just quite reserved the deformation space of lining rubber when pressurized, reduced the internal stress that produces when rubber contour projector and rubber shrink, increase working life, saved material simultaneously, reduced cost.
