Embodiment Construction

[0014] A cooling cavity is provided in the wall of the brake drum (1), and a fixed partition (18) is formed in the middle of the cooling cavity. The partition divides the cooling cavity into a water inlet cooling cavity (17) and a water outlet cooling cavity (19). ), there are 8-20 water passage holes (20) at the bottom of the partition, so that the inlet and outlet cooling chambers communicate with each other; the diameter of the water passage holes is 5-10 mm, and the outlet cooling chamber is provided with 2-4 heads clockwise. Rotating spiral fins (16). The stationary ring (4) is made of wear-resistant metal material, the outer diameter of the stationary ring is the same as the outer diameter of the brake drum, the inner diameter is the same as the inner diameter of the brake drum, and the thickness is 10-20 mm. The moving ring (3) is made of graphite with self-lubricating and wear-resistant properties, or ceramic or metal with self-lubricating and wear-resistant properties...

Abstract

Disclosed is a water cycle cooling device for automobile brake drums, wherein an upper surface of a brake drum is fixedly connected with a moving ring, the moving ring is in contact with a stationary ring in a zero clearance mode, the stationary ring is fixedly connected with a fixing block, a pressure spring is arranged on the fixing block, a cooling cavity is arranged inside a brake drum wall, the middle portion of the cooling cavity is fixedly connected with a baffle, the baffle divides a cooling cavity body into a water inlet cooling cavity and a water outlet cooling cavity, the bottom of the baffle is provided with a water hole, an annular water inlet groove and an annular water outlet groove are arranged between the moving ring and the stationary ring, a water inlet hole and a water outlet hole are arranged on the stationary ring and the fixing block, the water inlet hole is in communication with the annular water inlet groove, the annular water inlet groove is in communication with the water inlet cooling cavity, the water outlet hole is in communication with the annular water outlet groove, the annular water outlet groove is in communication with the water outlet cooling cavity, and the water inlet hole and the water outlet hole are connected with a water cooling tank through pipes. The device is subtle in concept, reasonable in design, good in cooling effect, capable of recycling cooling water, saving water sources, not damaging pavement and guaranteeing effectively normal operation of the brake drum, and convenient to use.

Description

technical field [0001] The invention relates to a component related to an automobile brake drum, in particular to a water circulation cooling device for the automobile brake drum. Background technique [0002] When the car is going downhill for a long time, the braking device of the car is continuously in the braking state for a long time. The long-term friction between the brake pad and the brake drum will generate a lot of heat, which will make the temperature of the brake pad and the brake drum rise to the highest level. Very high, brake failure, causing serious safety accidents. In order to reduce the temperature of the brake pads and the brake drum, the traditional method is to spray water directly on the outside of the brake drum when the car is going downhill to cool the brake drum. Due to the large amount of water used for spray cooling, the waste of water resources is large, and the road damage is accelerated. In winter, the road surface is icy, which is easy to br...
