Zhejiang Mingyuan Machinery Equipment Co., LTD. Introduction of tractor

Two kinds of suspension

One is the suspension of the traction motor and the moving wheel shaft connection, called the holding shaft suspension or half suspension. Using this suspension mode, the driving wheel through the rail joints and turnout generated by the impact vibration will be directly transmitted to the traction motor. Holding axle suspension is suitable for rolling stock with structural speed less than 120 km/h. The other is the frame suspension (or full suspension). The traction motor is fixedly suspended on the bogie frame, and various elastic connecting elements are added between the shaft end of the traction motor and the small and large gears to reduce the impact of vibration. Frame - mounted suspension is suitable for locomotives and vehicles with structural speeds higher than 120 km/h.

Zhejiang Mingyuan Machinery Equipment Co., LTD., said that when the traction transformer is used to power the DC series excited traction motor after the silicon rectifier or high power thyristor rectifier, the voltage added to the traction motor is pulsating voltage, so the traction motor is called pulse current traction motor. The "reversing" condition of high power pulse-current traction motor is more difficult. In addition, there are some additional losses inside the motor, which can cause the temperature rise of the motor. Therefore, some special measures should be taken in the design and structure of the pulse-flow traction motor to solve the two prominent problems of "reversing" and temperature rise.
