Background
At present, the wet brake is widely applied to various tire type running vehicles. The wet brake has the advantages of fast braking response, good sealing performance, strong pollution resistance, short relative braking distance, small abrasion and the like. The cooling mode of the wet brake is divided into a self-forming cooling mode and a forced oil circulation cooling mode according to the working environment and the braking frequency. The self-cooling mode is suitable for occasions where the heat dissipation of the wet brake is enough when the braking is not frequent, and the self-cooling mode has a simple structure but relatively weak cooling capacity. The forced cooling mode is suitable for occasions with frequent braking and insufficient heat dissipation of the wet brake, has relatively strong cooling capacity, but has a complex structure, generally needs accessories such as an external power source, a hydraulic control valve, a filter, a radiator and the like, and has high cost.
The problem to be solved by the application is to provide a wet brake with an automatic lubricating oil circulating device, which enables lubricating oil to flow between the wet brake and a bridge body to form automatic circulation under the condition of no need of an external power source; the lubricating oil absorbs part of heat of the wet brake to reduce the temperature of the wet brake, and the heat absorbed by the lubricating oil is dissipated to the air through the surface of the bridge body, so that the surface of the bridge body participates in heat dissipation, the heat dissipation area is enlarged, and the purposes of enhancing the heat dissipation and cooling of the wet brake are achieved.
Disclosure of Invention

Detailed Description
The invention will be further described with reference to the accompanying drawings:
referring to fig. 1 and 2, the wet brake with the automatic lubricating oil circulation device comprises a wet brake, a hub bracket, a rotor, a stop pin, a stator, an inner gear ring assembly, a lock nut, a bridge body and an oil pipe, wherein the hub bracket 2 is a part of the wet brake 1, the rotor 3 is connected with the hub bracket 2 through the stop pin 4 into a whole, the rotor 3 rotates along with the hub bracket 2, the lock nut 8 fixes the inner gear ring assembly 7 and the bridge body 9 together, the stator 5 is fixed with the inner gear ring assembly 7 through the stop pin 6, the stator 5 and the bridge body 9 are relatively static and can not rotate, a cooling channel 11 is formed by gaps among parts in the wet brake 1, and an oil supplementing channel 12 is formed by gaps among parts in the bridge body 9.
The rotor 3 is provided with a plurality of threads 3-1, when a vehicle runs, the rotor 3 can rotate relative to the stator 5 along with the hub bracket 2, the rotor 3 and the stator 5 form a screw pump in the rotating process, the screw pump pumps lubricating oil on the left side of the rotor 3 to the right side of the rotor 3 through the threads 3-1, and the lubricating oil on the right side of the rotor 3 flows through the wet brake 1 along the oil outlet channel 11 and finally flows out through the oil pipe 10.
When the vehicle is service braked, the wet brake 1 generates huge heat which is enough to raise the temperature of the wet brake 1; the vehicle travels after being braked, the wheel can drive the wheel hub bracket 2 and the rotor 3 to rotate together, the rotor 3 and the stator 5 form a screw pump in the rotating process, the screw pump pumps lubricating oil with lower temperature on the left side of the rotor 3 to the right side of the rotor 3 through the threads 3-1, the lubricating oil on the right side of the rotor 3 flows through the wet brake 1 along the cooling channel 11, and the lubricating oil flowing through the wet brake 1 absorbs part of heat of the wet brake 1, so that the temperature of the wet brake 1 is reduced; after absorbing part of heat of the wet brake 1, the lubricating oil flows out through the oil pipe 10 and finally flows into the bridge body 9, at the moment, the bridge body 9 is equivalent to a radiator, the heat brought by the lubricating oil is dissipated to the air through the surface of the bridge body 9, and the lubricating oil cooled by the bridge body 9 enters the left side of the rotor 3 through the oil supplementing channel 12 and circulates in the way. As the anti-pollution capacity of the rotor 3 and the stator 5 is very strong and is insensitive to the pollution level of the lubricating oil, the lubricating oil can be normally circulated without being filtered.
The embodiment has the obvious effects that under the condition of no need of an external power source, lubricating oil flows between the brake and the bridge body to form automatic circulation; the lubricating oil absorbs part of heat of the wet brake to reduce the temperature of the wet brake, and the heat absorbed by the lubricating oil is dissipated to the air through the surface of the bridge body, so that the surface of the bridge body participates in heat dissipation, the heat dissipation area is enlarged, and the purposes of enhancing the heat dissipation and cooling of the wet brake are achieved.
