The utility model discloses a further improvement scheme is, the ring channel is located rubber packing ring A's axial middle part position.

The utility model discloses a further improvement scheme is, the coaxial fixedly connected with rubber packing ring B in top of gland, rubber packing ring B's up end is higher than the up end of otic placode.

The further improvement of the utility model is that the upper end face of the rubber gasket B is 3-5mm higher than the upper end face of the ear plate.

the utility model discloses a further improvement scheme is, the coaxial annular groove of having seted up of up end of rubber packing ring B.

The utility model discloses a further improvement is, rubber packing ring A's up end is the corrugated surface structure, the lower terminal surface of gland seted up with rubber packing ring A up end assorted corrugated structure.

the utility model discloses a further improvement scheme is, the annular knurl structure has been seted up to the up end of otic placode.

Compared with the prior art, the utility model, following obvious advantage has:

Firstly, a gasket is arranged in an annular groove formed in the inner wall surface of an annular rubber ring A, and a damping rod of the automobile shock absorber is fixedly connected with the gasket. The automobile is at the in-process of traveling, and the power that automobile body and wheel vibration produced can conduct the junction to damping rod and packing ring, and because of road conditions and the reason of driving regulation, the load that the packing ring received is dynamic aperiodic load, and the packing ring is installed in the ring channel, and rubber packing ring A can take place deformation along with the load in all directions, prevents to act on the too big support frame that leads to of local stress on the support frame to damage to extension strutting arrangement's life.

The annular groove is located in the axial middle position of the rubber gasket A, so that the gasket is mounted in the middle position of the rubber gasket A, the main part of the force generated by vibration of the vehicle body circulates up and down, and the gasket is mounted in the middle position of the rubber gasket A and can play a good effect in the up and down directions.

Thirdly, the lug plate on the support frame is connected with the vehicle body, the rubber gasket B is fixed on the gland, the upper end face of the rubber gasket B is higher than the upper end face of the lug plate, and when the lug plate is fixed with the vehicle body, the rubber gasket B is in a compression state, so that the contact area between the vehicle body and the support frame is increased, and the stress on the support frame is reduced; meanwhile, when the vibration amplitude of the automobile is too large, when the rubber gasket A reaches the deformation limit, the rubber gasket B can also play a role in reducing stress through corresponding deformation.

and fourthly, the upper end face of the rubber gasket B is limited to be higher than the upper end face of the lug plate by 3-5mm, so that the rubber gasket B can be in a certain compression state, and the phenomenon that the compression amount is too large to influence the friction requirement at the joint of the lug plate and the vehicle body is avoided.

And fifthly, the upper end surface of the rubber gasket B is provided with an annular groove B, so that better compression and fixation effects can be achieved.

Sixthly, the upper end face of the rubber gasket A is of a corrugated structure and is matched with the corrugated structure of the lower end face of the gland, and the rubber gasket A can be prevented from moving when being stressed and deformed.

Seventhly, the knurling structure has been seted up to the up end of otic placode, can increase the frictional force that the bolted connection face when adopting bolted connection, plays better locking effect.
