Travelling motor heat dissipating system

Abstract

The invention discloses a travelling motor heat dissipating system. The travelling motor heat dissipating system comprises travelling motors, motor controllers, an electronic control water pump, a heat dissipater assembly and an expanding water tank; an inlet of the electronic control water pump is connected with a water outlet of the heat dissipater assembly and a water outlet of the expanding water tank through pipelines; a parallel connection manner is adopted between the travelling motors and the motor controllers, and the travelling motors and the motor controllers are both connected withan outlet of the electronic control water pump; electric ball valves and flow meters are arranged among the travelling motors, the motor controllers and the electronic control water pump; the four sets of motors and the four sets of motor controllers are correspondingly connected in parallel, and on the premise that the motors, the motor controllers, the water pump, the heat dissipater and the like are the same, the heat dissipating capacity of the motors is obviously improved; and meanwhile, one flow meter and one electric ball valve are assembled on each water way in parallel connection sothat the flow in each branch way is adjusted in real time, and the heat dissipating effect of the travelling motors is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of ground unmanned vehicles, and relates to a cooling system for a walking motor. Background technique [0002] As an important power component of an electric drive unmanned vehicle, the motor has high requirements on the motor. Whether the motor is running normally or not depends on the degree of heating of the motor. When the temperature of the motor is too high, it will not only hinder the normal operation of the parts, but also reduce the The output capacity of the motor is too low, so that the life of the motor is also greatly reduced, and in severe cases, the moving parts are stuck, resulting in potential safety hazards. [0003] The prior art has the following defects: (1) In the prior art, the motor is connected in series behind the motor controller, and the cooling effect of the motor is relatively poor. [0004] (2) When the left motor and the right motor in the heat dissipation system are connect...

[0002] As an important power component of an electric drive unmanned vehicle, the motor has high requirements on the motor. Whether the motor is running normally or not depends on the heating degree of the motor. When the temperature of the motor is too high, it will not only hinder the normal operation of the parts, but also reduce the The output capacity of the motor is greatly reduced, and the life of the motor is also greatly reduced. In severe cases, the moving parts are stuck, resulting in potential safety hazards.

[0003] The prior art has the following defects: (1) the motor is connected in series behind the motor controller in the prior art, and the cooling effect of the motor is relatively poor

[0004] (2) When the left motor and the right motor in the heat dissipation system are connected in parallel, manual gate valves are used to adjust the flow in each branch, and the valve opening is difficult to control accurately, and the flow adjustment is not accurate
