Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Examples

As shown in fig. 1 to 4, the present embodiment provides a high temperature resistant rubber shock absorbing gasket for an automobile, which includes an outer rubber gasket 1, a bent portion 11 is provided in the middle of the outer rubber gasket 1, and an annular stretching portion 12 is provided on the outer side of the bottom of the bent portion 11; still include tensile subassembly 2, tensile subassembly 2 includes fixed mounting 21 on annular tensile portion 12, inlays fixed plate 22, the wire rope 23 on the lateral wall of kink 11, and wire rope 23's one end and fixed mounting 21 fixed connection, the other end pass outer rubber pad 1 and fixed plate 22 fixed connection.

When the rubber shock absorption sealing gasket is used, the rubber shock absorption sealing gasket is arranged at a proper position, when two ends of the outer rubber gasket 1 are pressed, as shown in fig. 3, the position of the bending part 11 can generate downward bending deformation, the upper end of the outer rubber gasket 1 moves downwards in a deformation mode, namely, the fixing plate 22 moves downwards, and the fixing plate 22 pulls the annular stretching part 12 to deform towards the middle of the outer rubber gasket 1 through the steel wire rope 23 and the fixing part 21. When recovering elastic deformation, lean on the elasticity of outer rubber pad 1 itself on the one hand, of course, to a certain extent, be by the biggest position kink 11 of deformation recovering, through tensile subassembly 2's setting, can be with the elastic recovery power of annular tensile portion 12 act on kink 11, can accelerate the recovering of kink 11 on the one hand, on the other hand can improve anti-seismic performance to after using for a long time, still possess outstanding elastic recovery ability.

Further, the fixing member 21 is arc-shaped and fixedly fitted outside the annular stretching portion 12. The central angle of the fixing member 21 is larger than 180 °, so that the fixing member 21 can be prevented from being detached from the annular stretching portion 12 to some extent, and the annular stretching portion 12 and the fixing member 21 can be connected by adhesion.

Further, the upper and lower ends of the outer rubber pad 1 are provided with corrugated bosses 13. The outer rubber pad 1, the annular stretching part 12 and the corrugated protruding part 13 are integrally formed, and after the outer rubber pad, the corrugated protruding part 13 is extruded, so that a sealing effect can be achieved.

Further, the stretching assemblies 2 are provided in four groups in total and are uniformly distributed in the circumferential direction of the annular stretching section 12. The elastic recovery capability in the circumferential direction can be improved.
