Abstract

The invention discloses a multi-stage transmission output mechanism. The mechanism comprises a motor and two or more transmission assemblies which are connected in sequence. Each transmission assemblycomprises a driving disc, a transmission belt, a driven disc and an output shaft. The driven disc sleeves a surface of the output shaft, the transmission belt sleeves the surfaces of the driving discand the driven disc, the driving disc of a first transmission assembly sleeves the output end of the motor, and the driving disc of the next transmission assembly sleeves the surface of the output shaft of the previous transmission assembly. According to the multi-stage transmission output mechanism, a motor outputs through multi-stage transmission; an output torque of the motor can be distributed for one-time transmission conversion and two-time transmission conversion or N-time transmission conversion; and therefore, the output torque of the motor can be improved, large-torque output of thelow-power motor can be realized, energy consumption of the motor can be reduced, single use time of a storage battery for supplying power to the motor is prolonged, and in addition, speed adjustmentof a final output shaft can be realized.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a multi-stage transmission output mechanism and an electric vehicle using the multi-stage transmission output mechanism. Background technique [0002] Pure electric vehicles have many advantages such as environmental protection and energy saving. In recent years, their development has become increasingly prosperous, and there is a great tendency to replace gasoline vehicles one day. Generally speaking, electric vehicles use batteries as the energy source, and convert electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed of the vehicle. [0003] However, at present, most of the power transmission systems of electric vehicles adopt motor direct drive, the output torque of the motor is limited, the energy consumption of the motor is large, and the riding mileage of electric vehicles is not long. Conten...
