[0003] In the prior art, the rubber shock-absorbing bushing of the automobile frame generally includes three parts: a metal shell, an intermediate rubber body and an inner tube. The three parts are connected together to form a complete bushing. The traditional process is to directly connect the metal shell and the inner tube The tubes are connected together through the intermediate rubber body. Such a structure is easy to come out axially, and the rigidity is difficult to adjust. In order to enhance the comfort of the car, it is necessary to increase the rigidity of the rubber shock absorbing bushing of the frame, so it is necessary to design a structure that can adjust the rigidity.

Embodiment Construction
[0012] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:
[0013] Such as figure 1 As shown, the present invention mainly includes a metal inner tube 1, a rubber body 2 and a plastic outer tube 3, the metal inner tube 1 is located at the center of the plastic outer tube 3, and the rubber body 2 is filled between the metal inner tube 1 and the plastic outer tube 3, and The metal inner tube 1 and the plastic outer tube 3 are connected into one body through the rubber body 2 .
[0014] An annular protruding structure 4 is provided on the outer surface of the middle part of the metal inner tube 1, and the protruding structure 4 extends into the rubber body 2, and the protruding structure 4 improves the connection strength between the rubber body and the metal inner tube.
[0015] The front and rear end edges of the plastic outer tube 3 are provided with closing structures 5 inwardly, and the closing structures 5 ...

The invention relates to a vehicle rubber damping bushing, and belongs to the technical field of vehicle damping bushings. The vehicle rubber damping bushing comprises a metal inner pipe, a rubber body and a plastic outer pipe; an annular projection structure is arranged on the outer surface of the middle part of the metal inner pipe; the projection structure extends into the rubber body; and close-up structures are arranged on the front and back end edges of the plastic outer pipe to the inner side. The vehicle rubber damping bushing is simple, compact and reasonable in structure; ports of the plastic outer pipe can shrink to effectively prevent falling of the rubber body from the plastic outer pipe; the projection structure in middle of the metal inner pipe can guarantee no falling of the vulcanized rubber body from the metal inner pipe; and through two semicircular plastic outer pipes, the machining cost is effectively reduced.
Description
technical field [0001] The invention relates to an automobile rubber shock-absorbing bush, which belongs to the technical field of automobile shock-absorbing bushes. Background technique [0002] With the development of the economy, people's living standards are constantly improving, and people's overall requirements for vehicles are getting higher and higher, and they are increasingly pursuing convenience and comfort. Shock absorption is widely used in auto parts. Connected to existing rubber connections or even hydraulic shock-absorbing connections, shock absorption technology is increasingly used in vehicles. [0003] In the prior art, the rubber shock-absorbing bushing of automobile frame generally includes three parts: a metal shell, an intermediate rubber body and an inner tube. The three parts are connected together to form a complete bushing. The traditional process is to directly connect the metal shell and the inner tube. The tubes are connected together through t...
