Problems solved by technology

Therefore, if you only want to reduce the magnetic friction, the torque of the motor cannot be as large as expected
Therefore, in the electric assisted bicycle of the above-mentioned publication, although the torque is improved by providing the deceleration mechanism, it is unavoidable to complicate the structure and increase the size, so an improved method is desired.

Embodiment Construction

[0039] An embodiment of the present invention will be described below with reference to the drawings. Fig. 2 is a side view of a power-assisted bicycle with a control device according to an embodiment of the present invention. The frame 1 of the electric assist bicycle has a head tube 2 positioned in front of the vehicle body, a down tube 3 extending rearward and downward from the head tube 2, a rear fork 4 connected to the down tube 3 extending rearward, and a rear fork 4 extending from the down tube 3. The vehicle seat column 5 that the lowermost end stands upwards.

[0040] The front fork 6 is rotatably supported on the head pipe 2 . The front wheel 7 is supported on the lower end of the front fork 6 with a shaft, and a steering handle 8 is installed on the upper end of the front fork 6 . A brake rocker arm 9 is arranged on the steering handle 8 , and a cable 10 drawn from the brake rocker arm 9 is connected to a front wheel brake 11 fixed to the front fork 6 . Similarly...

Abstract

The present invention relates to a series-parallel combined driving system for mixed electric car using epicyclic train. Said ivnention can simplify control complexity of existent driving system, reduce quantity of accumulator and implement low consumption of energy and low discharge of waste gas. Said invention is characterized by that the internal combustion engine is connected with centre wheel by means of clutch and brake, the motor is connected with outer ring gear by means of brake, clutch and an inscribed gear, and the planetary gear is connected with main gear box by means of brake and clutch, and the drive power can be transferred onto car wheel of electric car by means of main gear box.

Description

technical field [0001] The present invention relates to a power-assisted bicycle, and more particularly to a power-assisted bicycle that compacts a motor as an auxiliary drive source and enables brisk running by reducing magnetic friction of the motor. Background technique [0002] There are known electrically assisted bicycles having a human drive system that transmits pedaling force, that is, a force applied by human power to the rear wheels, and a motor drive system that can add auxiliary power to the human drive system in accordance with the pedaling force. Japanese Patent Publication No. 2829808 discloses a motor-assisted bicycle in which a motor, which is an auxiliary drive source of a motor drive train, is incorporated into a hub of a rear wheel. In this electrically assisted bicycle, when the motor is not used for assistance such as downhill, the rotation of the magnetic poles stops, but the armature maintains the rotation with the rotation of the rear wheel. Therefo...
