Power driving device for oil and electricity hybrid motorcycle

Abstract

The invention discloses a power driving device for an oil and electricity hybrid motorcycle. The power driving device comprises a gasoline engine (1), a motor (2) and a gear position switching device for switching a low speed gear position and a high speed gear position, wherein a power switching device for switching power is arranged among the gear position switching device, the gasoline engine (1) and the motor (2) and connected with the gasoline engine (1) through a transmission shaft (3) and connected with the motor (2) through a clutch (4). The power driving device has the advantages of simple structure and convenience in manufacturing and mounting; by adopting the power driving device, the power can be switched steadily, and the safety performance is improved; and furthermore, the energy loss during mechanical power transmission is reduced, the mechanical fault rate is reduced, and the energy is saved.

Description

technical field [0001] The invention relates to an oil-electric hybrid motorcycle, in particular to a power drive device for an oil-electric hybrid motorcycle. Background technique [0002] At present, the power of traditional motorcycles only comes from gasoline engines, and with the continuous rise of oil prices, people often hope to find new energy sources to replace gasoline engines. For this reason, many manufacturers use electric motors to replace engines. However, using simple electric motors to drive motorcycles to walk, due to the limitation of batteries, the mileage is too short. In order to solve this problem, many manufacturers are using motorcycles A gasoline engine is installed on the motorcycle, relying on the gasoline engine to generate electricity, then flushing the generated electricity into the battery, and then supplying the electric energy in the battery to the electric motor. Although this can extend the mileage of the motorcycle, according to the law o...

For this reason, many manufacturers use electric motors to replace engines. However, using simple electric motors to drive motorcycles to walk, due to the limitation of batteries, the mileage is too short. In order to solve this problem, many manufacturers are using motorcycles A gasoline engine is installed on the motorcycle, relying on the gasoline engine to generate electricity, then flushing the generated electricity into the battery, and then supplying the electric energy in the battery to the electric motor. Although this can extend the mileage of the motorcycle, according to the law of energy conservation, the gasoline engine After generating electricity, it rushes into the storage battery. During this process, the electric energy is lost, which not only wastes gasoline, but also due to the influence of the power of the motor itself, when the motorcycle is under heavy load, the motor still shows the disadvantage of insufficient power. In order to solve this problem The problem is that some manufacturers use gasoline engine and electric motor to drive separately. The gasoline engine is used as power for heavy load and uphill, and the electric motor is used for no-load and downhill. Switching not only increases the operation process, but also wastes time. In order to realize the non-stop switching of power, people have designed an independent power switching device, relying on the power switching device to switch the power of the gasoline engine and the electric motor. However, it There are still the following disadvantages: 1. Because the speed of the gasoline engine does not match the speed of the electric motor, there will be an uncomfortable feeling of rushing forward or falling back when switching power; 2. Due to the rigid fit of gears when switching power, it makes the The gears in the power switching device collide with each other and make a knocking sound, which not only violates the common sense of mechanical design, but also, in serious cases, the mutual collision of the gears will damage the gears and cause potential safety hazards; 3. Since the power switching device is an independent part, Its gear switching device is far away, so that there are multi-stage transmission shafts in the power transmission between the generator, the motor and the power switching device, which increases the energy loss in the mechanical power transmission process
