Description of the invention: [Technical field to which the present invention pertains] The present invention relates to a bicycle and a driving type thereof, and an electric bicycle thereof. Zero [Prior Art] The convenience and ease of the body of the bicycle rider came out and was widely favored by consumers. Electric_Treading The current motor drive material for electric bicycles, the motor unit is set outside the front or rear wheels, and the motor shaft is parallel to the wheel shaft after being driven. Bite the second type: the motor is set on the bracket outside the rear or front wheel, and the motor shaft is perpendicular to the driven wheel axle. , , , car n: The motor is directly combined with the front or rear wheels, and directly becomes moving. ...^ axis. It is characterized by the main system of the motor with the front or rear wheel: four types: the motor is perpendicular to the pedal drive shaft, via the transmission element. = So far, most of the electric bicycles on the market have many, two, and three types of drive mechanisms, and the fourth category is a small number. The above-mentioned first: cheek transmission mode is shown in the new patent of the publication No. 522964 of the i. The motor A1 of the electric bicycle is disposed outside the rear wheel, so that the "shaft is parallel with the wheel axle after being driven. And by the transmission component 201238832 A2 page, the sprocket A) is not fixed in the rear wheel. The transmission mode is as shown in the figure. (4) The motor of the electric bicycle is set in the rear wheel and the frame is removed. On the B2, the wheel axle is driven by the vertical two after the drive. The sprocket B3 on the rear wheel. The drive-piece drives the fixed three-type transmission mode, as shown in Figure 3, Announcement No. M2597, No. 467091 The new type of child ^ 4 . Ming Cang reading 0 3, the motor of the electric bicycle is directly connected with the front wheel (2) as the axis of the wheel, and the axis of the motor is continued with the gas up to 盥偻m. :=== For the fourth type of transmission, please refer to the public ring of Figure 5 and the new patent No. 519〇87 of the announcement of Figure 6. The dry motor of the electric bicycle E1 is not protected against the front sprocket E2. Link, the motor El^= piece/4 and the chain are set straight, which mainly uses the front key wheel E2^= special rotation And the chain E5 drives the front sprocket E2, and the second and second parts are as shown in Fig. 6. The motor of the conventional electric bicycle rotates, and the motor F1 and the pedal transmission are smashed; (As shown in Fig. 7) The drive is straight to 2, and the material sprocket F2 is driven by the chain F4 to rotate the rear wheel.

Since the gear set is a precision mechanical component, ί, this kind of transmission is on the whole, the weight of the electric bicycle will be serious, and the weight of the electric bicycle will be on the side of the rear wheel, and it will be installed on the rear wheel. The step two that can be stood by the carrier will not be easy to occupy the space of the animal. The second step is as follows: 'The motor ci is wrapped inside the shaft as shown in Figure 3' and the main system of the motor 会 will follow the front wheel. C2 = · As shown in Fig. 4, the motor 卬 is fixed to the mandrel of the rear rim, and the wheel D2 is rotated. This type of transmission is like a 4-port port, and it needs to be specially ordered. Its manufacturing cost is better than that of the surface'. When the dynamic balance is not done, the car will travel up and down. This type of wheel is not manufactured separately. It also creates a problem of high manufacturing costs. 1 and the 5th type of transmission is very few, as shown in Figure 5, when the motor E1 is actuated, it will also drive the pedal and the front sprocket E2, 6 201238832 = travel, the knight must The feet are raised to avoid being hit by the pedals. 'At the same time, because of the waste of power and the reduction of electricity by driving the pedals, it is also necessary to turn the omnidirectional side (as shown in Figure 7).
