A new energy vehicle motor with small vibration amplitude and stable operation

Abstract

The invention relates to a new energy automobile motor with a small vibration amplitude and stable operation. The new energy automobile motor includes a casing, and a rotating shaft, a balance mechanism and a vibration damping mechanism which are arranged in the casing; the vibration damping mechanism comprises a first rotating wheel and a plurality of vibration damping components, and each vibration damping component comprises a vibration transmitting unit and two damping units; the balance mechanism comprises a second rotating wheel and two balance components, each balance component comprises a collar and two balance units, and each balance unit comprises a fixing rod, a side rod, a lever, a detection block, a sleeve, a sliding rod, a slider, a supporting rod and a first roller. According to the new energy automobile motor with the small vibration amplitude and stable operation, the vibration amplitude of the rotating shaft is reduced in a rotating plane, and the rotation of the rotating shaft is more stable; in addition, the balance mechanism weakens vibration of the rotating shaft in the axial direction, the rotation stability of the rotating shaft is enhanced, stable driving of the new energy automobile is facilitated, and the practicability of the motor is improved.

Problems solved by technology

[0003] In new energy vehicles, the motor plays a vital role as the power source of the car. The car motor mainly relies on the rotation of the rotating shaft to generate driving torque for the new energy vehicle to move forward. However, in the existing new energy vehicle motor, Only relying on bearings to provide auxiliary support for the rotation of the shaft will cause the shaft to vibrate in various directions during the rotation process, which will affect the stable driving of the car. If the inner diameter of the bearing is reduced to reduce the shaking range of the shaft during design, it is easy to The inner wall of the rotating shaft and the bearing is worn, which reduces the service life of the bearing and the rotating shaft, thus reducing the practicability of the existing new energy vehicle motor
