Abstract

PURPOSE: A hybrid motorcycle using a one-direction clutch is provided to convert power delivered to rear wheels easily depending on the options of a user. CONSTITUTION: A hybrid motorcycle using a one-direction clutch comprises a direct current motor armature(35), a cylindrical yoke(15), yoke discs(25,27), and a unidirectional clutch. The direct current motor armature is attached to the center axis of rear wheels. The cylindrical yoke is arranged around the direct current motor armature. A permanent magnet is arranged in the inner circumference of the cylindrical yoke. The outer circumference of the cylindrical yoke is attached to a tire. The yoke disc is attached to both sides of the cylindrical yoke. When the power is applied to the direct current motor armature to turn the rear wheels, a one-direction clutch releases the connection of the rear wheel sprocket and the yoke disc. When the power from an internal combustion engine is delivered to the rear wheel sprocket, the one-direction clutch mechanically connects the yoke disc with the rear wheel sprocket.

Description

HYBRID MOTORCYCLE USING ONE-DIRECTION CLUTCH}

The present invention relates to a hybrid motorcycle, and more particularly, to a hybrid motorcycle in which rear wheel drive by an electric motor and rear wheel drive by an internal combustion engine can be automatically switched without a separate operation of a driver.

Motorcycles are often used for the transport of small cargoes, such as postal delivery, food delivery and goods delivery in the city centre. Conventional motorcycles have used internal combustion engines, especially two-cycle gasoline engines, as power sources. The two-cycle gasoline engine makes it easy for the motorcycle to climb steep hills due to its large power and torque. However, gasoline engines are not suitable for use in urban areas, such as residential areas such as apartments, residential areas, or the dense areas, because the engine emits exhaust gas generated from the burned gasoline and generates a loud noise from the engine during acceleration. It pollutes urban air and causes noise pollution in residential areas, especially at night. Motorcycles run not only on steep hills, but also on flat and downhill roads.Most motorcycles are used for the purpose of delivering mail, food, and goods in the city center. It is near and only part of it is a steep hill or downhill. When gasoline engines are used to start motorcycles traveling on these roads, fuel consumption is unnecessarily high. This is because gasoline engines should be kept running even when large propulsion is not needed, such as when driving on flat or downhill roads.

The present invention devised to solve the shortcomings of a motorcycle started by the conventional internal combustion engine described above is to provide a hybrid motorcycle that can run using an internal combustion engine when climbing a steep hill, and can use an electric motor on a flat or downhill. Its purpose is to.

Another object of the present invention is to provide a hybrid motorcycle capable of automatically interrupting the transmission of internal combustion engine power to the rear wheels when the internal combustion engine is started, and automatically stopping the transmission of electric motor power to the internal combustion engine when the electric motor is started. There is.

The present invention to achieve the above object is a motor in which the central axis of the rear wheel is fixed to the body side frame, the power of the internal combustion engine installed in the front half of the body is transmitted to the rear wheel by a chain and a sprocket so that the rear wheel is driven around the central axis In the cycle, a DC motor armature is fixedly installed on the central axis of the rear wheel, a cylindrical yoke is arranged around the DC motor armature and a permanent magnet is arranged on the inner circumferential surface and the outer circumferential surface is fixed to the tire. A yoke disk slidably coupled to the central shaft is attached, and a power is supplied to the DC motor armature between the rear wheel sprocket and the sprocket side yoke disk to release the connection between the yoke disk and the rear wheel sprocket when the rear wheel rotates. The power of the internal combustion engine is transmitted to the rear wheel sprocket. Surface is characterized in that the one-way clutch for mechanically connecting between the yoke disk and the rear wheel sprocket.

According to the present invention having the above-described configuration, when power is supplied to the DC motor armature to rotate the yoke and the yoke disk, that is, when the electric motor rotates, the boiling force is automatically boiled so that the rotational force is not transmitted to the rear wheel sprocket and the internal combustion engine When the power of the internal combustion engine is transmitted to the rear wheel sprocket through the chain, the rotational force of the rear sprocket is automatically connected to the yoke disk and the yoke, so that the rear wheel sprocket is easily transmitted to the rear wheel according to the power selection of the user. When climbing a steep hill while converting power, an internal combustion engine can be used for driving, and on the flat or downhill, an electric motor can be used.

A driver driving in a residential complex or commercial complex starts driving with a DC motor when most of the flat or downhill is expected according to the expected driving route. At this time

Since the DC motor armature 35 is fixedly installed on the central axis 27 of the rear wheel 1, and the permanent magnet 17 is arranged on the inner circumferential surface of the DC motor armature 35, the DC motor armature is excited. The magnetic field and the repulsive force of the permanent magnet are generated so that the yoke 15 rotates, and the yoke disk 27 and the second block 41 fixed to the yoke 15 also rotate. When the second block 41 rotates, the case 49 of the one-way clutch pin module fixed inside the second block also rotates in the same direction, and as shown in FIG. 4A, the pin 51 is eccentric. The case 53 of the one-way clutch pin module and the friction ring 61 of the first block 57 are separated from each other by moving in the wide direction of the pocket 53. Therefore, even if the yoke disk 27 and the tire 23 rotate by the DC motor, the rotational force is not transmitted to the rear wheel sprocket 5b or the internal combustion engine 3.

When the uphill is expected from the beginning or when the uphill is encountered while driving by the DC motor, the driver turns off the start of the DC motor and starts the internal combustion engine 3. Then, the power of the internal combustion engine is transmitted to the friction ring 61 of the front wheel sprocket 5a, the chain 7, the rear wheel sprocket 5b, and the first block 57, as shown in FIG. The rotation of the 61 moves the pin 51 in the narrow width direction of the eccentric pocket 53, so that the case 49, the pin 51, and the friction ring 61 of the one-way clutch pin module are fixed. The rotational force of the friction ring 61 is transmitted to the case 49 of the one-way clutch pin module and the second block 41, the yoke disk 27, and the tire 23 connected thereto. Therefore, it is possible to travel using an internal combustion engine when climbing a steep hill while converting power transmitted to the rear wheel very easily according to the power selection of the user, and to use an electric motor on a flat or downhill.
