Abstract
The utility model relates to the field of automobile brake drums, and particularly relates to a rear brake drum with heat radiation slots. The rear brake drum consists of a bolt hole, an assembly hole and a brake drum body, and is characterized in that a bolt hole and an assembly hole are formed at the left end of the brake drum body; six heat radiation slots are formed on the outer surface of the brake drum body along the circumferential direction; and the heat radiation slots and the brake drum body are integrated. According to the technical scheme, the heat radiation area can be greatly increased through the structure of the heat radiation slots; when an automobile runs, the service life of the brake drum is prolonged; and the process is simple, so that the raw materials are saved, and the casting production cost is reduced.
Description
Technical field
The utility model relates to the automobile brake drum field, is a kind of Back-braking drum with radiating groove.
Background technique
Because China's automobile overload phenomenon is commonplace, and uneven at mine road, The mountains are high and the roads are steep, big especially to the destruction of brake drum.General Back-braking drum appearance design is a smooth surface, because brake drum is one of main parts size of brake system of car, the brake area outside heat diffusion area of brake drum is limited; Assembling is installed the back and is formed enclosed construction; This structure is when brake drum is worked, and heat radiation is slow, and the brake drum temperature is high; Be prone to the brake drum be full of cracks, cause automobile brake drum early failue.
Summary of the invention
The purpose of the utility model is that a kind of new Back-braking drum will be provided, and reaches the temperature that reduces brake drum through the heat sinking function that increases brake drum self.
The technological scheme of the utility model is: be made up of bolt hole, pilot hole and brake drum body; It is characterized in that bolt hole and pilot hole being arranged at the left end of brake drum body; Outer surface edge at the brake drum body circumferentially is provided with radiating groove; Radiating groove and brake drum body are as a whole, and the quantity of radiating groove is six.
Owing to adopted technique scheme, can increase heat diffusion area greatly through the radiating groove structure, during vehicle operating, improved the working life of brake drum; And technology is simple, has practiced thrift raw material, has reduced the Foundry Production cost.
