Tricycle with electric motor |
摘要 |
A tricycle with an electric motor in which two rear wheels 4 and 4 are driven by not only an electric motor 5, but also pedals 6 with manpower. A rotational force of the pedals 6 is transmitted to drive shaft 9 via first bevel gears 8a and 8b and then transmitted to a one-way clutch 7 via second bevel gears 10a and 10b from the drive shaft 9. The output of the one-way clutch 7 is then transmitted to the two rear wheels 4 and 4. The electric current to the electric motor is a pulse current and its pulse width is controlled to be shorted in relation to a braking operation.
