Abstract

The invention relates to the field of new energy automobiles, in particular to a new energy automobile high-speed driving motor shaft. The new energy automobile high-speed driving motor shaft comprises a U-shaped connecting plate, a lubricating and cooling high-speed driving component, a power cut-off component, a position calibration component and the like. The U-shaped connecting plate is provided with the lubricating and cooling high-speed driving component, the power cutting-off component and the position calibration component. Through cooperation of cylindrical supporting rollers, balls and devices on the balls, a high-speed motor shaft body can bear large impact force due to the fact that the cylindrical supporting rollers longitudinally support the high-speed motor shaft body, and the balls transversely support the high-speed motor shaft body, friction force of the high-speed motor shaft body during high-speed rotation can be small; and the longitudinal support and the transverse support are matched with each other, so that the high-speed motor shaft body ensures high-speed rotation while bearing multi-directional centrifugal force, and safe and stable high-speed rotation of the high-speed motor shaft body is ensured.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a high-speed drive motor shaft for new energy vehicles. Background technique [0002] In recent years, new energy vehicles have developed rapidly. As the power source of new energy vehicles, the motor bearing is a special bearing specially used on the motor, and the motor shaft is an important part of the motor. The link of electromechanical energy conversion is used to support the rotating parts, transmit torque and determine the relative position of the rotating parts to the stator, and the motor shaft will rotate at high speed. Therefore, the motor shaft must have reliable strength and rigidity to ensure the preset design function realization. [0003] The motor shaft has an inseparable relationship with the high-speed motor. The motor shaft will generate a lot of heat when it rotates at high speed. If the motor shaft is not cooled in a reasonable way, it will cause it to e...
