Problems solved by technology

[0002] The driving school's coach cars are mainly manual transmission models, and more than 70% of the time the coach cars are used in the venue. During the training, the cars are in low gears, low speeds, and frequently start and stop operating conditions, resulting in low-efficiency engine work. interval, high fuel consumption and heavy pollution
Pure electric vehicles have the characteristics of zero emission and no pollution, but currently pure electric vehicles have not been widely promoted in the driving school market
[0003] The existing electric vehicles are mainly automatic transmission models. The technical solution is a motor and a single-speed ratio reducer structure. There are fewer manual transmission models. Due to the limitation of the motor structure, the motor shaft cannot be directly connected to the flywheel like the engine crankshaft. It is difficult to use traditional engines and multiple gears. Gearbox transmission system, if forcibly applied, will cause the gearbox shaft centering assembly difficulties, transmission system vibration and abnormal sound defects

Abstract

The invention discloses an electric instructional car transmission system. The system comprises a motor, a connecting flange, a coupling, a flywheel, a clutch assembly and a gearbox which are arrangedin sequence, wherein the right end of the motor is provided with a motor outer end face and a convex output shaft arranged in the middle of the motor outer end face. An inner shaft hole is formed inthe middle of the output shaft; a flange cavity is formed in the middle of the connecting flange; the outer end surface of the motor is centered and connected with the left end of the connecting flange; the right end of the connecting flange is in centering connection with the left end of the gearbox; the output shaft is connected with the left end of the flywheel in a centered mode through the coupler, the right end of the flywheel is connected with the clutch assembly in a centered mode, the left end of the first gearbox shaft is inserted into a spline forming hole in the middle of the clutch assembly, the coupler, the flywheel and the clutch assembly are all located in the flange cavity, and the output shaft, the connecting flange and the first gearbox shaft are coaxially arranged. According to the system, the centering precision is high, vibration abnormal sounds of a transmission system are not likely to be caused, operation is easy, and the manufacturing cost and the assembling cost are low.
