Silicone oil shock absorber, shock absorption connecting structure and engineering machinery

The utility model relates to a shock absorber and provides a silicone oil shock absorber, a shock absorption connecting structure and engineering machinery in order to solve the problem that an existing silicone oil shock absorber only has a shock absorption effect in the axial direction of a center shaft. The silicone oil shock absorber comprises a center shaft and filling rubber which are fixedly connected in a cup-shaped shell through vulcanization, a damping cup arranged in the shell, and a pressing plate fixedly connected with a cup opening of the damping cup, a closed cavity filled with silicone oil is formed below the filling rubber, and the pressing plate is fixedly connected with the lower end of the center shaft. The upper side face of the pressing plate makes contact with the filling rubber, the cup bottom of the damping cup is immersed in the silicone oil and provided with a damping hole communicating the inside and the outside, and the upper portion of the damping cup is filled with gas. The sili
