Problems solved by technology

The installation cost of this type of water spray cooling device is low, only more than one thousand yuan, and it has a good cooling effect. However, in the actual use process, several problems were found that could not be solved. The main problem is one: due to the rotation of the brake drum, the spray nozzle is fixed, and the brake The drum is prone to cracks due to uneven heat and cold, which will cause the brake drum to be scrapped prematurely; two: the large water tank containing water exceeds 400 kg or even weighs more than 1,000 kg, which will increase the fuel consumption of the car and reduce the payload of the car. The large water tank needs to be filled with water every tens of kilometers, at least three times a day, and many water points are needed along the way, which wastes water resources and is time-consuming and expensive

Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with accompanying drawing:

[0040] The best basic embodiment of the invention:

[0041] Please refer to the accompanying drawings, in the embodiment, the rotary water inlet and outlet device (1) consists of a static chamber (13) that is sleeved on a cylinder or a stepped cylinder rotating shaft (12), and the static chamber (13) is for setting There are double circular water jackets with water inlet and outlet pipe joints (20), (21), and the rotating shaft (12) is a cylinder provided with water inlet and outlet channels (22), (23) and water inlet and outlet joints (18), (19) Or a stepped cylinder, and three O-shaped water seal rings (14), (15), (16) are arranged between the two rotating sliding surfaces, so that the water in and out are isolated from each other and the water does not leak out. Using the rotating shaft ( 12) The screw hole (17) that one end is provided with, put the screw thr...

Abstract

Automobile brake drum automatic circulation cooling system and control method, characterized in that: the rotating water inlet and outlet device (1 ) as well as water pumps and water pipes to circulate the coolant in the water jacket brake drum and the coolant in the brake radiator, and use sensors, controllers, and manual switches to work together to control manually or automatically, so as to reduce brake pressure. Drum temperature purpose.

Description

technical field [0001] The invention relates to the technical field of cooling the brake drum of an automobile, in particular to the technical field of automatically cooling the brake drum of an automobile by using circulating cooling liquid. Background technique [0002] At present, many serious traffic accidents occur every year, most of which are caused by illegal operation of trucks, mechanical failures and other reasons, among which 60% of serious traffic accidents are caused by brake failure. This is because drum brakes (such as Figure 9 The structural section of the drum brake drum is shown in the cross-sectional diagram), the drum brake has the advantages of large braking force and low cost, but it has not overcome the shortcomings of poor heat dissipation, and the current trucks are overloaded and heavy, which makes braking and deceleration for a long time During the process, a large amount of heat is generated between the brake pad and the brake drum, which cannot...
