FIELD: machine building.
SUBSTANCE: invention relates to a drive mechanism and method of ensuring oil supplying in an automatic transmission in a towing process. When the rotating speed of main shaft (12) of the transmission is detected when a driving motor is stopped, main shaft (12) connected to wheel (7) of the transmission is connected to a drive shaft of oil supply pump (17) of the transmission. Towing process can be detected when the drive motor of a vehicle is stopped according to transmission output shaft sensor (13), and main shaft (12) can be connected to the shaft of oil supply pump (17) in a condition that the towing process has been identified to realize oil supplying.
EFFECT: enabling the design simplification.
