Abstract
Provided is a twin-stage rubber shock absorber. The twin-stage rubber shock absorber comprises a belt pulley. A ring-shaped groove is arranged on the right end face of the belt pulley. A torsion vibration damper comprising an inertia ring, a rubber ring and a hub is arranged in the ring-shaped groove. A cushion plate is arranged on the inner lateral face of the hub. A rubber ring chamber is formed by the cushion plate and the belt pulley. A rubber ring is arranged in the rubber ring chamber. An axial limit core plate is arranged in the inner ring of the rubber ring. End faces of the axial limit core plate are connected with the hub by the cushion plate. The cushion plate, the rubber ring and the axial limit core plate are assembled together into a bending vibration damper. Modules used to solve bending vibration are added into an existing rubber damper so as to reduce space and noise produced by engine vibration and further improve the coziness of a whole vehicle. The twin-stage rubber shock absorber has the advantages of being simple in structure, convenient to use and low in manufacture cost.
Description
Technical field
The utility model relates to a kind of rubber shock absorber that is applied to motor, especially a kind of twin-stage rubber shock absorber.
Background technique
At present, the requirement that reduces the engine luggine noise improves constantly, and all will overcome the belt tension power that causes engine luggine, the factors such as inertial force in the running, and wherein rubber shock absorber just is used for one of vitals of control engine crankshaft torsional vibrations; Cause motor to produce the reason of noise, also have a kind of flexure vibrations.
Summary of the invention
The utility model provides a kind of twin-stage rubber shock absorber, has solved the problem of motor flexure vibrations noises, has improved the travelling comfort of car load.
The technical solution of the utility model is: a kind of twin-stage rubber shock absorber, comprise belt pulley, the right side of belt pulley is provided with annular groove, be provided with the torsional vibration damper that is formed by inertia ring, rubber ring and wheel hub in the annular groove, it is characterized in that: on the inner side surface of wheel hub pad is housed, pad and belt pulley form the rubber ring chamber, in the rubber ring chamber rubber ring are housed, the interior ring of rubber ring is equipped with the axial limiting central layer, and the end face of axial limiting central layer is connected with wheel hub by pad; Above-mentioned pad, rubber ring and axial limiting central layer are combined into crooked vibration damping equipment.
Further restriction to technique scheme is provided with friction ring between described belt pulley and the inertia ring.
To the further restriction of technique scheme, described axial limiting central layer is the cylindrical shell with flange, is provided with friction ring between the end face of axial limiting central layer and belt pulley.
Beneficial effect: a kind of twin-stage rubber shock absorber, in existing rubber shock absorber, increased the device that solves flexure vibrations, so not only saved the space, also reduce the engine luggine noise, thereby improved the travelling comfort of car load.The utility model, simple in structure, easy to use, fabricating cost is low.
