[0002] With the enhancement of global environmental protection awareness and the adjustment of energy structure, traditional fuel locomotives gradually show their deficiencies in energy conservation and emission reduction. Therefore, the development of new - energy rail traction locomotives has become an inevitable trend in the rail transit field. Although existing new - energy locomotives have achieved the goal of low - carbon environmental protection to a certain extent, there is still room for improvement in aspects such as power transmission efficiency, braking performance, and battery management systems.

[0065] Working principle: Each of the six axles on each set of three-axle bogies 14 is equipped with a permanent magnet synchronous motor. These motors are fixed to the outer shell of the axle reduction box through the motor mounting flange, and are connected to the axle reduction box through splines, so that the torque generated by the motor is efficiently transmitted to the wheels, thereby driving the locomotive forward. When the locomotive needs to move, the motor receives instructions from the control room and starts to operate, converting electrical energy into mechanical energy, and transmits it to the wheels through the axle reduction box, so that the locomotive can move. The locomotive is equipped with unit brakes 13, which are located at both ends of each set of wheels. When the locomotive needs to slow down or stop, the braking system will be activated, and the braking force will be applied through the brakes to slow down the speed of the locomotive until it stops completely. The intelligent driver controller component in the driver's cab 3 is responsible for receiving the driver's operating instructions, and processing this information through the on-board computer system VCU to accurately control the operating parameters of the motor. The all-in-one battery controller is responsible for monitoring the status of the power battery 9, such as voltage, current, temperature, etc., and controlling the charge and discharge according to the actual situation. In addition, it is linked with the all-in-one battery controller and its battery fire extinguisher 18. Once an abnormal situation is detected, the fire extinguishing procedure is immediately started to protect the safety of the battery pack. In order to keep the motor and battery within a suitable operating temperature range, the locomotive is equipped with a motor all-in-one controller and a motor water cooling radiator 6 and a power battery water cooling radiator 7. The heat generated by the motor and battery during operation is taken away by circulating coolant to maintain the thermal balance of the system. The 24V low-voltage battery in the small machine room 1 can provide the locomotive with the power required for starting when the main power supply is disconnected.
