The two covers of the electric motor are fixed to the rear wheel edge. The output shaft of the engine extends through the covers and is connected by bearings on both sides of the stator of the electric motor. The output shaft drives the rear wheel edge through one of the covers. The electric motor can directly drive the rear wheel edge. The two different drive modes can be operated simultaneously or individually by the operation of the speed control device and the selection device.

Description

Hybrid motor cycle {HYBRID MOTORCYCLE}

The present invention relates to a motorcycle, and more particularly to a hybrid motorcycle driven by a gas engine and an electric motor under an operating mode in a manual mode, an automatic mode or a combined mode.

While motor-driven motorcycles have been developed over the last few years, conventional motorcycles are generally driven by gas engines. The gas engine provides a large torque and can also be operated under large loads. However, these gas engines consume a lot of fuel from zero speed, and this fuel consumption improves when driven at a higher speed. Electric motors generate less noise and save fuel, but they provide greater torque and can not operate under heavy loads. Electric motorcycles are suitable for operating at low speeds on even roads.

Hybrid cars have long been used, but hybrid motorcycles are rarely seen. Taiwan Utility Model No. 098212258 discloses a hybrid motorcycle and includes a gas drive system installed in such a motorcycle for driving a rear wheel. The electric drive system includes an electric motor and a battery that provides power to the electric motor connected to the front wheel axle. A handle for controlling the speed and the handle includes a first switch and a second switch. The first switch controls activation of the gas drive system and the second switch controls activation of the electric drive system so that the user can switch between different modes of operation. The handle has a cable for controlling the fuel valve of the gas drive system. The handle further has a Hall device having a power control cable connected to the electric drive system for controlling the speed under the electric drive mode. Under the gas drive mode, the gas drive system drives a generator unit that generates power whose voltage is raised by a voltage booster to provide power to the battery.

Another Taiwan Utility Model No. 99207316 discloses a hybrid motorcycle that includes a first power source that is a hybrid engine, a motor generator coupled to the engine, a transmission system that transmits power of the engine to a rear wheel, and a second A power source, and a control unit for controlling the engine, the motor generator, and the electric rear wheel hub. The control unit controls the engine and the motor generator, and the engine power is transmitted to the rear wheel by the transmission system. Another drive mode is created by the control unit that controls the electric rear wheel hub to drive the rear wheels directly to reduce losses when kinetic energy is delivered.

In a first example, the electric motor is installed on the rear wheel so that the gas engine drives the rear wheel, and the user can select the gas driving system or the electric driving system to drive the motorcycle. The second example uses two batteries to ensure that the hybrid motorcycle continues to function.

In the first example, the electric motor is connected to the rear wheel, and the gas engine drives the rear wheel, and a user can select the gas driving system or the electric driving system to drive the motorcycle. Both the front wheel and the rear wheel cooperate to drive the motorcycle, but the front wheel becomes too heavy due to the electric motor, making it difficult to control the rotation. In addition, manual switching between the two drive systems can reduce the user's concentration. The second example uses two batteries to ensure that the hybrid motorcycle continues to function, but the second example also describes how to control the switching between the two modes and also between the drive systems The structure is not described in detail.
