Abstract
The invention discloses a damping rubber cushion comprising a rubber base, a piston and a piston cylinder, wherein one end of the piston is in sliding fit with the inside of the piston cylinder, and the other end of the piston is fixedly connected to the rubber base; and the piston is filled with air, and the bottom of the piston cylinder is communicated with an air caching chamber. When being used, the damping rubber cushion is arranged between two parts to be damped, the piston cylinder is fixedly arranged in one of the parts, and the rubber base is arranged on the other part. Same as the traditional rubber cushion, the rubber base has damping and buffering functions. When the two parts drive the piston cylinder and the rubber base to oppositely move under the action of an external force, the air in the piston cylinder is compressed by virtue of the piston, and part of air is enabled to enter the air caching chamber, so that the damping and buffing effects are taken; and when the piston cylinder and the rubber base move in a way of being far away from each other, the air in the air caching chamber enters the piston cylinder to form a circulation. Therefore, the damping rubber cushion has double damping functions, and the damping effect is greatly optimized.
