Novel fuel-electro double mode integral variable speed driving mechanism

Abstract

The invention relates to a novel fuel-electro double mode integral variable speed driving mechanism which belongs to a driving device used for electric cars and motorcycles. The novel fuel-electro double mode integral variable speed driving mechanism is characterized in that the left crank shaft of a petrol engine crank shaft and the center shaft of a motor are on the same centerline, centrifugal clutches are respectively arranged among the left crank shaft, the engine crank shaft and the motor which share the same overrunning clutch, and the connection matching of the left crank shaft, the petrol engine crank shaft and the motor is cut off in the middle position between the overrunning clutch and the centrifugal clutches at one end of the motor. Because the left crank shaft of the petrol engine crank shaft and the center shaft of the motor are designed to be eccentric, the two sets of the centrifugal clutches are used for driving one set of overrunning clutch to operate. Thus, the motor can not operate because the centrifugal clutches do not operate when the petrol engine operates, and the centrifugal clutches of the petrol engine can not operate when the operation modes of the motor are switched over. The invention has the advantages of simple structure, low manufacturing cost, energy saving, stable starting and high grade ability, and provides the best structural transition from motorcycles to electric cars.

Description

technical field [0001] The invention relates to a transmission device for an electric vehicle and a motorcycle, in particular to a novel oil-electric dual-mode integrated speed change transmission mechanism. Background technique [0002] Battery-driven car is deeply favored by people because of multiple factors such as environmental protection, easy to use and safety. The structure of existing battery-driven car 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 gearbox and then transmitted to the special rear axle to drive th...

Problems solved by technology

At present, there is a problem in all mopeds, that is, when the mopeds powered by gasoline engines are short of gasoline, they cannot drive, and they do not belong to the direction of development in the period of energy shortage.

[0004] For this reason, the inventor has applied for "A New Type of Electric Vehicle Transmission Mechanism", "A New Type of Electric Vehicle Speed-up Transmission Mechanism" and "A Kind of Engine with Dual Power Drive Electric Motorcycle" in 2007 and 2008 , patent number (including application) 200720007028.3; 200710008961.7; 200820145749.5; 200810071877.4;
