Implementation method of submerged water circulation cooling system for automobile brake drum

Abstract

The invention relates to an implementation method for an immersed water circulation cooling system of an automobile brake drum. The implementation method is characterized in that immersed water circulation overall cooling of the surface of the brake drum can be achieved by using a cylindrical steel rim (4), a flexible water bag (5), an annular water stop plate (6), an annular water guide plate (7), a water storage tank (11) and a water storage box and a water pipe of a water suction pump (10), which are mounted in each tire rim of an automobile, for circulating cooling water in the cylindrical steel rim, and enabling a power switch, a sensor and a controller to work together for achieving manual or automatic control. The implementation method has the advantages of quickness in cooling, higher cooling efficiency, stable cooling effect, less water consumption, capability of achieving automatic circulation and recycling of cooling water and the like.

Description

technical field [0001] The invention relates to the technical field of cooling the brake drum of automobiles, in particular to the technical field of cooling the brake drum by automatic circulation of cooling water. Background technique [0002] The brake drum is a necessary facility for the car to decelerate and stop. When the car decelerates and stops for many times, the brake system is in the braking state for a long time, especially when the car is going down a long slope. When the temperature exceeds a certain value, the friction coefficient between the brake pad and the brake drum will drop sharply, resulting in thermal decay, causing brake failure, which is easy to cause traffic accident. In order to prevent the thermal degradation of the brake system, the simplest and most widely used system implementation method is to use the air pressure water tank to spray the cooling water directly to the outer surface of the brake drum through the nozzle to cool the brake drum....

AI Technical Summary

Problems solved by technology

In actual operation, this kind of cooling method consumes a lot of water, needs to add water frequently, has slow cooling speed, poor efficiency, unstable performance, and cooling water accumulates cold and heat on the brake drum locally, which is easy to cause the brake drum to crack and shorten the use of the brake drum. Long life, cooling water sprayed onto the road, causing the road to be slippery and causing hidden dangers to vehicles behind, etc.

The water spraying process is done manually by the driver. Since the cooling water is sprayed on the narrow space between the tire rim and the brake drum, if the nozzle bracket is slightly deformed, the cooling water cannot be sprayed on the brake drum, which wastes cooling. Water has no cooling effect. This cooling method requires the driver to make irregular inspections and adjustments. There is no safety monitoring facility, and it is easy to cause driving accidents due to the negligence of the driver.
