Abstract

The invention discloses a self-circulation cooling automobile brake drum device, which is provided with a water cooling chamber and a water inlet and outlet channel on a brake drum, an inner ring is connected with the brake drum, the inner ring is sequentially provided with a bearing, a sealing ring, an annular impeller, a sealing ring, an annular impeller and a sealing ring bearing, and is sleeved with an outer ring, wherein the outer ring is provided with the water inlet and outlet channel, the end surfaces of the outer ring and the inner ring are provided with end covers, and the rotation directions of the two annular impellers are opposite. The cooling water of the self-circulation cooling automobile brake drum device can be recycled, and can not pollute the road, so the running safety of the automobile is ensured (i.e. the pollution of sprayed water on the road does not exist), high temperature generated when the automobile brake drum brakes is greatly reduced, and the water supply and drainage circulation of the cooling water in the brake drum is ensured.

Description

technical field [0001] The invention relates to an automobile brake device, in particular to a self-circulation cooling automobile brake drum device. Background technique [0002] The existing steam wheel brake drum adopts the cooling mode of external spraying water to cool. However, the disadvantage of this method is that it causes damage and slipperiness of the road, causing potential safety hazards for light vehicles, and poor cooling effect during braking. Patent No. 93239119.2 utility model patent discloses a "vehicle brake cooling device". The device is fixed on the bottom plate of the automobile brake with a flow distributor, and the cooling liquid is sent to the flow distributor that does not rotate with the wheels through the radiator through the radiator liquid outlet pipe. The liquid inlet channel of the outer ring flows into the liquid inlet channel of the inner ring of the distributor that rotates with the wheel through the gap of the sealing ring that does not...
