A high-speed drive motor shaft for new energy vehicles

Abstract

The present invention relates to the field of new energy vehicles, in particular to a high-speed drive motor shaft for new energy vehicles, including a U-shaped connecting plate, a high-speed lubricating and cooling component, a power cut-off component, and a position calibration component; the U-shaped connecting plate is provided with Lubricating and cooling high-speed drive components, power cut-off components on the U-shaped connecting plate, and position calibration components on the U-shaped connecting plate. Through the cooperation of the cylindrical support roller, the ball and the upper device, since the cylindrical support roller supports the shaft body of the high-speed motor longitudinally, the shaft body of the high-speed motor can bear a large impact force, and because the ball supports the shaft body of the high-speed motor laterally, The frictional force of the high-speed motor shaft can be reduced during high-speed rotation, and the longitudinal support and horizontal support cooperate with each other, so that the high-speed motor shaft can guarantee high-speed rotation while bearing multi-directional centrifugal force, ensuring the high-speed motor shaft Safe and stable high-speed rotation.

Description

A high-speed drive motor shaft for new energy vehicles technical field [0001] The present invention relates to the field of new energy vehicles, in particular to a high-speed drive motor shaft of a new energy vehicle. Background technique In recent years, the rapid development of new energy vehicles, motor as the power source of new energy vehicles, wherein the motor bearing is A special bearing specially applied to the motor, and the motor shaft is an important part in the motor, as the motor and the device. It is the link of electromechanical energy conversion between equipment, which is used to support rotating parts, transmit torque and determine the force of rotating parts to stator. relative position, and the motor shaft will rotate at high speed, therefore, the motor shaft must have reliable strength and rigidity to ensure the preset Implementation of design functions. The motor shaft has an inseparable relationship with the high-speed motor, and the motor s...
