Acceleration transmission mechanism of novel electric vehicle

Abstract

The invention discloses a novel speed-raising transmission mechanism for an electric motor car, which belongs to a transmission device for an electric bicycle or an electric motorcycle. The middle part close to the rear wheel on the lower end of a frame of the electric motor car is provided with a motor which rotates a gear of a central axis to drive a speed-raising gear to play a role in raising the speed and to drive an overrunning coupler to rotate to work; a belt pulley drives a rear idler to work so as to achieve infinite variable speed effect; and the rear idler rotates a central speed transforming gear, then an axle sliding gear rotated by a sliding gear rotates an axle. The speed-raising transmission mechanism utilizes the overrunning coupler in the belt transmission of the motorcycle; meanwhile, the speed-raising transmission mechanism is combined with the prior speed-change mechanism of the electric motor car or the electric motorcycle to achieve the infinite variable speed. Therefore, the speed-raising transmission mechanism contributes to an ideal electric motor car with the independent motor, stable starting, quick speed raising, strong capacity of climbing, long sliding time and electricity conservation.

Description

technical field [0001] The invention relates to a transmission device of an electric bicycle or an electric motorcycle, in particular to a novel speed-increasing transmission mechanism of an electric vehicle. Background technique [0002] The development of electric vehicles is a social demand of today's industrial production. Electric vehicles are very popular due to various factors such as environmental protection and safety. And the structure of existing electric vehicle mainly all is that motor is directly installed on the main shaft of trailing wheel, realizes its operation. Although the structure is simple, there are many shortcomings such as difficulty in starting, high power consumption, poor climbing ability, and some even have to get off the car when going uphill, and the vehicle speed is too slow. Another kind of electric vehicle is an electric vehicle equipped with a gearbox and a rear axle. This structure uses the output of the motor to be decelerated by the g...

Problems solved by technology

For this reason, the inventor applied for "A New Type of Transmission Mechanism for Electric Vehicles", patent number: 200720007028.3 and application number: 200710008961.7. After more than one year of production practice, it was found that the mechanism with the centrifugal clutch would be empty, and The motor is required to reach 6000 revolutions per minute, so there are bad problems such as motor heating, which needs further improvement
