Embodiment Construction

[0014] A cooling chamber is provided in the wall of the brake drum (1), and a fixedly connected partition (18) is made in the middle of the cooling chamber, and the partition divides the cooling chamber into a water inlet cooling chamber (17) and an outlet cooling chamber (19 ), there are 8-20 water holes (20) at the bottom of the partition, so that the water inlet cooling chamber and the water outlet cooling chamber are connected; direction of rotation of the spiral fins (16). Make static ring (4) with wear-resistant metal material, static ring external diameter is identical with brake drum external diameter, internal diameter is identical with the internal diameter of brake drum, thickness 10-20 millimeter. The moving ring (3) is made of graphite with self-lubricating and wear-resistant performance, or ceramic or metal with self-lubricating and wear-resistant performance, the outer diameter is the same as the outer diameter of the brake drum, the inner diameter is the same a...

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 an automobile brake drum. Background technique [0002] When the car is going downhill for a long time, the brake device of the car is in the braking state continuously for a long time, and the friction between the brake pad and the brake drum for a long time will generate a lot of heat, so that the temperature of the brake pad and the brake drum will rise to If it is too high, the brakes will fail, causing serious safety accidents. In order to reduce the temperature of brake pads and brake drums, the traditional method is to directly spray water on the outside of the brake drums when the car is going downhill, so as to cool down the brake drums. Due to the large amount of water used for spray cooling, the waste of water resources is large, and it also accelerates the damage of the road surface. In winter, the water-sprayed...
