Technical Field

[0001] The utility model relates to the technical field of vehicle auxiliary products, in particular to a circulating heat dissipation and forced cooling system for a wet brake of a mining vehicle. Background Art

[0002] Mining transport vehicles are vehicles for transporting bulk materials such as ores and waste rocks in mines. It can be said that mining transport vehicles play a crucial role in mines. Wet brake pads are important spare parts on mining transport vehicles and play a crucial role in the safety of the vehicles. Due to friction, existing wet brake pads generate a large amount of heat, and after long-term use, the friction pads are prone to burning out, affecting the performance and service life of the wet brake pads, and even threatening the safety of vehicle driving. Content of the Utility Model

[0003] In view of this, in order to solve the problem that the wet brake pads generate heat due to friction and thus affect the performance of the friction pads in the technical background, the utility model provides a circulating heat dissipation and forced cooling system for a wet brake of a mining vehicle, and the specific technical solutions are as follows:

[0004] A circulating heat dissipation and forced cooling system for a wet brake of a mining vehicle includes a hydraulic oil tank, an oil pump, a radiator, and wet brake pads connected in sequence through pipelines. The wet brake pads are connected with a plurality of oil cavities, each oil cavity includes an oil outlet and an oil inlet, the oil inlets of each oil cavity are connected to each other, and the oil outlets are connected to the hydraulic oil tank. The normal-temperature oil medium in the hydraulic oil tank is sent to the radiator by the oil pump for air cooling and then sent to the oil cavities in the wet brake pads, and the heat generated by the wet brake pads during braking is cooled through heat exchange with the oil medium.

[0005] Further, the oil cavities include four identical first oil cavities, second oil cavities, third oil cavities, and fourth oil cavities, and the oil cavities are connected by pipelines.

[0006] Further, the hydraulic oil tank, the oil pump, the radiator, the wet brake pads, and the oil cavities form a 360-degree circulating system.

[0007] Adopting the above technical solutions, the following beneficial effects are achieved:

[0008] In the utility model, the normal-temperature medium in the hydraulic oil tank is pumped to the radiator by the oil pump for air cooling, and then pushed to the oil cavities of the wet brake pads by the remaining pressure of the oil pump. A large amount of heat generated by the brake pads during vehicle braking is cooled back to the oil tank through the return oil pipe, realizing the cooling of the wet brake pads, thereby preventing the problem that the performance of the wet brake pads is affected due to too high temperature of the wet brake pads.

[0012] Embodiment 1: A circulating heat dissipation and forced cooling system for a mine wet brake includes a hydraulic oil tank 1, an oil pump 2, a radiator 3, and wet brake pads 4 that are sequentially connected through pipelines. The wet brake pads 4 are connected with a plurality of oil chambers, and each oil chamber includes an oil outlet and an oil inlet. The oil inlets of each oil chamber are connected to each other, and the oil outlets are connected to the hydraulic oil tank 1. The normal temperature oil medium in the hydraulic oil tank 1 is sent to the radiator 3 by the oil pump 2 for air cooling and then sent to the oil chambers in the wet brake pads 4, and the heat generated by the wet brake pads 4 during braking is cooled through heat exchange with the oil medium.

[0013] The oil chambers include four identical first oil chambers 5, second oil chambers 6, third oil chambers 7, and fourth oil chambers 8, and the oil chambers are connected by pipelines.

[0014] See Figure 1 As shown, the present utility model is an internal circulation liquid cooling heat dissipation. The oil pump 2 includes a pump that transports hydraulic pressure to the radiator 3. The inside of the oil chamber has oil flowing in at one end and out at the other end through circulation. The hydraulic oil pipes of the radiator 3 and the brake oil chamber are connected, and the hydraulic oil pipes of the oil chamber and the hydraulic oil tank 1 are connected, thus forming a 360 internal circulation device.

[0015] The principle is to pump the normal temperature oil medium in the hydraulic oil tank 1 through the energized oil pump 2 to the radiator 3 for air cooling, and then push it to the oil chambers of the wet brake pads 4 by the remaining pressure of the pump. A large amount of heat generated by the brake pads during vehicle braking is cooled through the return oil pipe back to the fuel tank, achieving temperature reduction and improving the safety and stability of the brake.
