Wet disc brake cooling device for electric wheel mining vehicle and cooling method thereof

Abstract

The invention discloses a wet disc brake cooling device for electric wheel mining vehicle and a cooling method thereof. The cooling device comprises a cooling fan and a rear axle housing, the top of the rear axle housing is provided with an air inlet penetrating into the rear axle housing, the top of the air inlet is fixedly connected with an air duct, and the air duct communicates with the air inlet; and an air outlet is formed in the bottom of the cooling fan. The first traction motor, the second traction motor and the radiator are all installed in the rear axle housing, cold air is fed intothe rear axle housing through the air duct by means of the cooling fan, the first traction motor, the second traction motor and the radiator can be forcibly cooled, and especially when the radiator is cooled, The radiator can be effectively cooled through convection air ducts generated by the spiral fan blades in the first mounting cover and the second mounting cover, the heat dissipation capacity of the radiator is remarkably improved, high-temperature oil entering the radiator is rapidly cooled, and the wet disc brake cooling device has the advantages of being simple in structure, safe andreliable.

Description

technical field [0001] The invention relates to the technical field of brake cooling, in particular to a cooling device and a cooling method for a wet disc brake of an electric wheel mining vehicle. Background technique [0002] The self-weight and rated load of the electric-wheel mining vehicle have high requirements on the performance of the braking system. Safe and efficient wet disc brakes are generally used. Wet disc brakes will generate a lot of heat during operation, and a radiator needs to be installed outside the brake. Relies on fluid that is constantly circulating through the brakes and radiator to dissipate the heat generated during braking. [0003] However, the existing technical scheme is that the radiator is installed on the front of the electric wheel mining vehicle, relying on the natural ventilation generated when the vehicle is running to dissipate the heat of the oil in the radiator. When braking for a long time, the brake cannot be released in time by r...

Problems solved by technology

[0003] However, the existing technical scheme is that the radiator is installed on the front of the electric wheel mining vehicle, relying on the natural ventilation generated when the vehicle is running to dissipate the heat of the oil in the radiator. When braking for a long time, the brake cannot be released in time by relying on natural ventilation. The generated heat is dissipated, resulting in high temperature of the braking system, which affects the safety and reliability of braking. In addition, the existing technology can solve this problem by increasing the capacity of the radiator, but the structure is huge and the overall layout of the vehicle is difficult.
