Abstract
The utility model discloses a rubber bush, comprising an inner tube (1), a rubber body (3) and an outer tube (2), characterized in that: two ends of the outer tube (2) bend inwards and a position-limit and restriction structure for the rubber body (3) is formed along the axle direction. The axial movement of the rubber body is limited to greatly reduce the relative movement between the rubber body and the bonding area of the inner tube and the outer tube and the bond destruction probability. Simultaneously the stress way of the rubber body is changed from the compression and cutting from the pure cutting, so as to increase the axial loading performance of the product and increase the service life of the product.
Description
Technical field
The utility model relates to a kind of rubber bushing.
Background technique
Chassis product on the automobile adopts the lining form more, and stressing conditions is complicated, need bear the dynamic and static load of all directions, and force way has tension and compression, the pendulum etc. of shearing, reverse, incline.
The rubber bushing that generally adopts is the straight cylinder type structure at present, axially do not having spacing to rubber body or constraint, rubber body is born pure shear shear force, and that rubber bears the ability of shearing load is relatively poor, be easy to generate the fatigue ruption and the bond damage of shear direction, have a strong impact on the fatigue life of product.
The model utility content
Goal of the invention: the purpose of this utility model is at the deficiencies in the prior art, and the rubber bushing that a kind of axial carrying capacity is strong, life of product is high is provided.
Technological scheme: rubber bushing described in the utility model, comprise interior pipe, rubber body and outer tube, the inward at both ends bending of described outer tube is at the spacing and restraining structure that has axially formed described rubber body.
By bottling technique, size of outer tube is reduced into Φ 53.2mm by original Φ 54.4mm, thereby has removed internal stress.
By the shaping bending technique, the outer tube two ends are bent into the fillet of R8.7mm.Reduce the influence of part shearing force.
The beneficial effects of the utility model are: 1, the utility model passes through the redesign of product structure and the application of bending technique, two ends at product, outer tube is curved inwardly, at the spacing and restraining structure that has axially formed rubber body, the force way of rubber body is changed into the boil down to master by pure shear, brought into play the strong advantage of rubber bearing capacity; 2, the utility model structural limitations the axial displacement of rubber body, the relative displacement of rubber body and interior pipe, outer tube adhesive surface is reduced significantly, reduced the probability of bond damage significantly; The utility model structure is changed to compression+shearing with the force way of rubber body by the pure shear dress simultaneously, has improved the axial bearing capacity of product, improves life of product.
Description of drawings
Fig. 1 is the structural representation of existing rubber bushing;
Fig. 2 is the utility model product structure schematic representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
Embodiment: as shown in Figure 2, a kind of rubber bushing, pipe 1, rubber body 3 and outer tube 2 in comprising, the inward at both ends bending of described outer tube 2, at the spacing and restraining structure that has axially formed described rubber body 3, the external diameter of described outer tube 2 is 53.2mm, and the inward at both ends of described outer tube 2 bends to the fillet that radius is 8.7mm.
The utility model product is interior pipe, outer tube and rubber body directly to be vulcanized obtain transitional product (sulfuration part), will vulcanize part again and obtain final products through closing in and bending.
Claims (3)
