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

A kind of automobile brake drum device of self-loopa cooling

Technical field

The utility model relates to brake device for car, specifically a kind of automobile brake drum device of self-loopa cooling.

Background technology

Existing steamer brake wheel adopts the type of cooling of outer shower water to cool off.But the shortcoming of this method is to cause the damage of highway and wet and slippery, causes the potential safety hazard of light-duty vehicle, and the glancing impact cooling performance is poor.The patent No. is that 93239119.2 utility model patents disclose a kind of " car brake cooling mechanism ", this device is fixed on the car brake base plate with flow distributor, by the logical radiator drain pipe of radiator refrigerant fluid is delivered to not in the liquid inlet channel with the flow distributor outer shroud of wheel revolutions, and by not flowing in the liquid inlet channel that encircles in the flow distributor with wheel revolutions with the gap of the seal ring of wheel revolutions, by cooling liquid bath feed tube refrigerant fluid is delivered in the cooling liquid bath on the brake wheel periphery again, refrigerant fluid is got back to another liquid inlet channel of ring in the flow distributor through the cooling bath drain pipe, by not getting back to the tapping channel of flow distributor outer shroud with the space of the seal ring of wheel revolutions, with water pump refrigerant fluid is sucked back in the radiator then, make brake wheel reach the purpose of forced heat radiation.Though the type of cooling that this patent can outer shower water is cooled off, need with water pump and the power supply of driving engine storage battery, if electrical generator storage battery fault, this device just can not be worked, and can not play cooling effect at this moment.

The utility model content

It is more convenient that the purpose of this utility model provides a kind of use, joint liquid medicine resource, the automobile brake drum device that can not pollute the road surface, not need the self-loopa of outer make-up water pump and other power to cool off.

The technical solution of the utility model is: the automobile brake drum device of self-loopa cooling comprises brake wheel, it is characterized in that being provided with on brake wheel water cooling chamber reaches into and out of water channel, be connected with an inner ring with brake wheel, bearing, seal ring, annular impeller, seal ring, annular impeller, sealed bearing are housed on this inner ring successively, and be with an outer ring, have on the outer ring into and out of water channel, at the end face of outer ring and inner ring end cap is arranged, wherein two annular impeller rotation directions are opposite.

Wherein:

Have on the end cap and automobile brake base plate bonded assembly locating piece.

Brake wheel can be structure as a whole with inner ring.

The structure of annular impeller is: there is a water channel space centre at ring, and the edge of ring is a blade.

Coolant inlet pipe in the automobile brake drum device of self-loopa cooling is connected with water tank, and coolant outlet pipe is connected with radiator, is connected temperature gage and compression indicator between coolant outlet pipe and the radiator.

The automobile brake drum device of self-loopa cooling of the present utility model, cooling water expansion tank can reclaim, can not pollute the road surface, guarantee running safety (promptly not having the pollution of shower water road pavement), and greatly reduce the high temperature that automobile brake drum produces at glancing impact, do not need outer make-up water pump and other engine installation, can make the water supply and the draining circulation of cooling water expansion tank in the brake wheel, reach the self-loopa cooling.As long as wheel one rotates, this device will automatic circulation, and not being subjected to automotive engine is out-of-run restriction.Particularly saved precious water resource.
