The invention further adopts the technical scheme that: the damping strip end I and the damping strip end II are respectively of cylindrical structures.
The hollow inner cavity is of a cylindrical structure.
The mass disc I and the mass disc II are both disc structures with fixing holes in the middle.
Due to the adoption of the technical scheme, the motor vehicle suspension shock absorber has the following beneficial effects:
the damping device comprises a rubber damping, a mass disc I, a mass disc II, a mounting bolt and a disc fastening bolt, wherein the rubber damping comprises a damping strip body, a damping strip end I and a damping strip end II, the damping strip body is of a strip-shaped structure provided with a hollow inner cavity, and liquid damping is filled in the hollow inner cavity. The invention eliminates noise by canceling wave front generated in running and engine running (vibration) and second-order wave front generated by the automobile, thus solving the problems that the vibration noise is overlarge due to the engine running and the frame in the running process of the existing automobile, the noise is transmitted into the automobile by the suspension system, and the like.
The technical features of the vehicle suspension shock absorber according to the present invention will be further described with reference to the drawings and embodiments.

Detailed Description
The utility model provides a motor vehicle suspension supports shake ware, includes rubber damping, quality disc I, quality disc II, mounting bolt and disc fastening bolt, rubber damping includes damping strip body, damping strip end I and damping strip end II, damping strip body is for the rectangular shape structure that is equipped with the cavity inner chamber, and this cavity inner chamber is filled with liquid damping and is airtight structure, cavity inner chamber be cylindrical structure, liquid damping after the filling also is cylindrical structure, utilizes the cushioning effect that rubber damping played when the atress to reach shock attenuation amortization during the use. The damping strip is characterized in that the damping strip end I and the damping strip end II are respectively located at two ends of the damping strip body, bolt holes I corresponding to the mounting bolts are formed in the damping strip end I, bolt holes II corresponding to the disc fastening bolts are formed in the damping strip end II, and the mass disc I and the mass disc II are respectively arranged at two sides of the damping strip end II through the disc fastening bolts. The damping strip end I and the damping strip end II are respectively of cylindrical structures, and axial lines on the damping strip end I and the damping strip end II are mutually perpendicular. The mass disc I and the mass disc II are both disc structures with fixing holes in the middle.
The rubber damping is a rubber damping which is formed by molding a rubber damping material into a hollow inner cavity, the hollow inner cavity is filled with liquid damping, a damping strip end I at one end of the rubber damping is provided with a bolt hole I, the bolt hole I is mainly used for being fixed on a frame hole at the opposite angle of an automobile suspension through a mounting bolt, a damping strip end II at the other end of the rubber damping is of a circular rubber damping structure with the same size as a mass disc, the center of the damping strip end II is provided with a bolt hole II, and the bolt hole II is mainly used for a disc fastening bolt to pass through and sequentially fix the mass disc I, the damping strip end II and the mass disc II into a whole. The mass disc I and the mass disc II are both made of cast iron into a circular mass disc, a fixing hole with screw threads is arranged in the middle of the mass disc, and the fixing hole is mainly used for being installed and fastened with a disc fastening bolt. The disc fastening bolt is made into a round screw, and one end of the round screw is a hexagonal screw cap and is mainly used for unscrewing and fastening the disc fastening bolt. One end of the disc fastening bolt is provided with screw threads and is mainly connected with a screw thread fixing hole of the mass disc I.
