The invention relates to the improvement of the variable-speed transmission system of an electric remote control vehicle, which takes a counter-rotating motor whose shell stator can also rotate relatively as the power output center, and transmits the motor power at the two output ends of the shell stator and the axial rotor to the front and rear mechanical differentials through transmission shafts respectively, and then uses the differential to make the vehicle move forward. The two transmission shafts between the motor and the differential can be selectively locked, so that the output power of the motor can make the wheels have different rotational speeds through the locking of different transmission shafts.
Claim: A variable-speed transmission system of an electric vehicle, including: a motor; Clutches respectively connected with two output shafts of the motor; Differential with different tooth ratios connected with clutch through transmission shaft; Rotating shafts respectively connected with four wheels and controlled by a differential. Characterized in that the motor is a counter-rotating motor and consists of a shell stator, an axial rotor, two electrode copper rings and a bearing, and the motor is internally provided with necessary components such as magnetic poles and windings, so that the axial rotor and the shell stator can rotate relatively after being electrified; Two electrode copper rings in contact with the carbon brush with power supply are arranged at appropriate positions on the outer surface of the stator of the shell, so that the motor can continuously supply power when rotating, and bearing supports are arranged on both sides in axial contact with the shell. Electricity is supplied in the opposite direction. When electric energy is input into the pre-winding from the carbon brush through the slip ring, the shell stator and the axial rotor can operate relatively, so that the motor power can be output at relative forward and backward speeds through the rotor shaft and the output shaft of the shell stator.
