Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of hybrid electric drive manufacturing and maintenance, and in particular to a self-driven high-speed running-in flushing system and method. BACKGROUND

[0002] In the production and manufacturing process of hybrid electric drive, the driving motor as the core power component directly determines the performance, efficiency and reliability of the whole vehicle. In the manufacturing process, after the machining and assembly of the motor, bearing, gear and other precision parts, metal chips, burrs, dust and other impurities are inevitably left inside. If these impurities are not completely removed, they will cause abnormal wear of the moving pair, oil passage blockage, even motor short circuit and other serious faults in subsequent operation, greatly reducing the service life and reliability of the product.

[0003] The traditional running-in flushing technology usually relies on external load motor to reverse drive the output shaft of the electric drive assembly through mechanical connection for rotating running-in. This method has low running-in speed and limited effect. Limited by the performance and safety of the external driving equipment, the running-in speed is usually difficult to exceed 1500r / min, which is far lower than the high-speed state of thousands or even tens of thousands of revolutions of the motor in actual operation. Therefore, the motor is difficult to reach the ideal high-speed running state, so that the running-in effect is not complete, affecting the performance and service life of the motor. At the same time, since the speed is difficult to reach the actual working state of the motor, the oil flow at this speed cannot effectively flush and carry away the small impurities hidden in the oil way and the gap between the parts. If these residual impurities accumulate too much, they will cause wear and tear when the motor is running, which poses a potential risk of failure. SUMMARY
