Dynamic automatic cooling system for brake hub of heavy truck

Abstract

The invention provides a dynamic automatic cooling system for a brake hub of a heavy truck, and the system comprises a water storage tank arranged in a frame; a controller which is arranged on the frame, wherein the controller is used for controlling the water outlet amount of the water storage tank; a plurality of nozzles which are arranged in the brake hubs of the wheels, wherein the nozzles are communicated with the water storage tank through water spraying pipes; and a plurality of temperature sensors which are arranged in brake hubs of the wheels, wherein the temperature sensors are electrically connected with the controller. According to the dynamic automatic cooling system for the brake hub of the heavy truck, the cooling effect of the brake hub of the heavy truck is improved.

Description

technical field [0001] The invention belongs to the technical field of automobile refrigeration systems, and in particular relates to a dynamic automatic cooling system for brake hubs of heavy trucks. Background technique [0002] At present, there are two main ways to improve the cooling effect of heavy-duty truck brakes: one is to directly install a hydraulic retarder, which can use the principle of liquid damping to reduce the speed of the vehicle, with high retarding efficiency and good heat dissipation , but it has the disadvantages of long separation time and power loss when not working, especially when it is used for heavy trucks, the structure is complex and the cost is high. The initial purchase cost is about 20,000-30,000 yuan, and the later modification price will be higher. At present, only high-end trucks will be equipped; the second is to install a cooling water tank directly under the frame, fill the water tank with compressed air through an air pump, or direc...

[0002] At present, there are two main ways to improve the cooling effect of heavy-duty truck brakes: one is to directly install a hydraulic retarder, which can use the principle of liquid damping to reduce the speed of the vehicle, with high retarding efficiency and good heat dissipation , but it has the disadvantages of long separation time and power loss when not working, especially when it is used for heavy trucks, the structure is complex and the cost is high. The initial purchase cost is about 20,000-30,000 yuan, and the later modification price will be higher. At present, only high-end trucks will be equipped; the second is to install a cooling water tank directly under the frame, fill the water tank with compressed air through an air pump, or directly pour the water in the water tank on the outer wheels through a water pipe through a water pump. This modification cost is low and widely applicable, and it has become the mainstream modification method at present, but the disadvantage is that the cooling effect is poor and the cooling time is uncontrollable. The brake hub that actually acts as a brake has not been sufficiently cooled. Cooling water poured directly on the wheels outside and drained away
