Abstract

The invention provides a protection structure for a new energy bus driving motor. The protection structure comprises a bottom plate, the bottom plate is provided with a protection cover for enclosingthe side surface of the motor, the upper surface of the bottom plate is provided with a bracket, the bracket is fixedly provided with a rotating shaft, and the rotating shaft is rotatably provided with two rotating arms which are oppositely arranged and are used for fixing the driving motor. The rotating shaft is sleeved with two torsional springs which are opposite in torque direction and correspond to the rotating arms in a one-to-one mode, one spring foot of each torsional spring is connected with the corresponding rotating arm, the other spring foot of each torsional spring is connected with the rotating shaft, an output shaft of the driving motor is provided with a first output gear, and the rotating shaft is provided with a second output gear meshed with the first output gear. The technical problem of circumferential vibration of a motor is solved.

Description

technical field [0001] The invention relates to a protective structure for a drive motor of a new energy passenger car. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. The motor is represented by the letter M (the old standard is D) in the circuit, and its speed can change with the input voltage and current, and it can be used as a power source for electrical appliances or various machinery. Because the motor speed is variable, the moment of inertia changes when the rotor speed changes, so its vibration is mainly the circumferential vibration generated when the rotor speed changes. [0003] In the prior art, an invention patent titled "a protective device for high-power variable-frequency motors" with an authorized announcement number of CN108599434B and an authorized announcement date of 2020.04.07 was disclosed, including the main body of the motor protective...
