Abstract
A brake drum of a heavy-duty car comprises the brake drum; a drum ring/sleeve is arranged on the outer side of the brake drum; a liquid storage chamber is arranged between the drum ring/sleeve and the brake drum, and filled with cooling liquid; a liquid feed port and an air exhaust port which are communicated with the liquid storage chamber are formed on the drum ring/sleeve, and are correspondingly provided with screws in sets; the drum ring/sleeve is made of steel plates and is tightly welded on the outer side of the brake drum; and reinforcing ribs are uniformly arranged on the inner side wall of the drum ring/sleeve. The brake drum has the advantages of simple structure, reasonable design, good cooling effect, great friction factor, low manufacturing cost and little maintenance work, effectively solves the problem that the brake drum of heavy-duty cars can heat easily, reduces accidents caused by brake failure, and prolongs the service life. In addition, the brake drum is suitable for heavy-duty car and other cars.
Description
Technical field
The utility model relates to a kind of heavy motor vehicle brake drum.
Background technology
At present, what heavy-duty truck was generally commonly used is the outer drum brakes of opening, brake facing and brake drum carry out friction braking, because heavy-duty truck self is heavy, load carrying ability is big, inertia is big, particularly in long-time abrupt slope down or lower long slope driving process, it is more frequent to touch on the brake, and brake drum easily heating causes friction coefficient to reduce, often cause brake failure, cause the person, vehicle, property accident.
The utility model content
The utility model purpose is to provide a kind of can the cooling automatically to increase the heavy motor vehicle brake drum of friction coefficient.
To achieve these goals, the utility model adopts following technical scheme: a kind of heavy motor vehicle brake drum, comprise brake drum, the brake drum outside is provided with drum circle/cover, be provided with fluid reservoir between drum circle/cover and the brake drum, be provided with refrigerant fluid in the fluid reservoir, drum enclose/put be provided with the spout that is communicated with fluid reservoir and exhausr port also corresponding supporting setting screw screw rod.
Described drum circle/cover is made by steel plate, and tight weld is in the brake drum outside.
Evenly be provided with reinforced rib on the madial wall of described drum circle/cover.
The utility model is simple in structure, reasonable in design, and it is effective to cool, and friction coefficient is big, has alleviated the easy heating problem of HD truck brake drum effectively, has reduced the brake failure accident, and can improve the service life of brake drum.Cheap for manufacturing cost, maintenance capacity is very little, is not limited only to be applicable to heavy-duty truck, also applicable to other various automobiles.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a left view of the present utility model.
The specific embodiment
Embodiment; As shown in Figure 1 and Figure 2, the heavy motor vehicle brake drum comprises brake drum 1, and brake drum 1 outside is provided with drum circle/cover 2, is provided with fluid reservoir 3 between drum circle/cover 2 and the brake drum 1, is provided with no water coolant in the fluid reservoir 3, play the effect of cooling, and period of service is longer.Drum circle/cover 2 be provided with the spout 4 that is communicated with fluid reservoir 3 and exhausr port 5 also corresponding supporting setting screw screw rod so that fluid injection and exhaust use.The position of spout 4 and exhausr port 5 can according to circumstances be provided with, and for example can be arranged on drum circle/cover 2 aft end faces.Drum circle/cover 2 is made by steel plate, and tight weld is in brake drum 1 outside.Evenly be provided with reinforced rib on the madial wall of drum circle/cover 2, improve the intensity of drum circle/cover 2.During work, refrigerant fluid is injected by spout 4,, and then screw and screw the screw rod sealing accordingly simultaneously by the air exhaustion of exhausr port 5 with fluid reservoir 3.
Claims (3)
1. heavy motor vehicle brake drum, comprise brake drum, it is characterized in that: the brake drum outside is provided with drum circle/cover, be provided with fluid reservoir between drum circle/cover and the brake drum, be provided with refrigerant fluid in the fluid reservoir, drum enclose/put be provided with the spout that is communicated with fluid reservoir and exhausr port also corresponding supporting setting screw screw rod.
2. heavy motor vehicle brake drum according to claim 1 is characterized in that: described drum circle/cover is made by steel plate, and tight weld is in the brake drum outside.
