2. Description of the prior art,

Recognized the problem of energy resources. With the aim of reducing the consumption of petroleum products demand of the vehicle, mechanically driven or driven by human muscle force. In particular, the bike is inexpensive and can provide the effect of the bike. Currently, Biking is a popular pastime.

The bike driven by human muscle force, adapted for short distances or for use at your leisure, but not for large distances.

As a consequence, the market offers a bike with mechanical drive with the motor. When the rider gets tired, he/she can switch to a mechanical drive in order to use a bike at a great distance. However, in motors with a mechanical drive and brake mechanisms bike with a mechanical drive is used, the design of other machines. Motor with mechanical drive and brake mechanism are eccentric, which requires larger konfigurazio the aqueous space and restricts the position of the Assembly.

Usually the motor with a mechanical drive and brake mechanism are located between the shaft of the rear wheel and the rear support. Thus, the bike can't keep his balance and motor with a mechanical drive and brake mechanism take up the most space. In addition, the bearing surface of the eccentric torsion brake mechanism is limited. After a certain period of time the gear is severely worn, which leads to disruption of normal operation.

Thus, the inventor of the present invention has devoted himself based on his many years of practical experience, to address the aforementioned problems associated with the traditional bike with a mechanical drive, and the development of a perfect and practical transmission device.

SUMMARY of the INVENTION

The main aim of the present invention is the provision of an electric motor and the brake mechanism, which is placed on the rotating shaft (torsion shaft)connected to the pedal levers that will reduce the configuration space and keep balance of the bike.

This object is achieved transmission device containing the drive mechanism is placed on the shaft, which is located between the two levers pedals of a Bicycle.

The drive mechanism includes a history is nick physical strength of the person or the source of electricity to bring the bike in motion.

By using the above-mentioned technical means, the unit mechanical actuator drives the power shaft and transmits power to the first ratcheting mechanism through the braking unit so as to engage the toothed wheel for the translational motion of the bike. When the toothed wheel is rotated, the second ratchet will not result in the movement of the rotating shaft (torsion shaft) levers pedals. Conversely, when the levers pedals pressed to move the rotating shaft and engaging the second ratchet to rotate the gear wheel, the first ratchet will not result in the movement of the braking unit and the unit mechanical drive.

Thus, the unit mechanical actuator levers pedals are managed separately without affecting each other. As the power block axis mechanical drive, and the output axis of the braking unit are hollow rods. The rotating shaft levers pedals inserted directly through the unit mechanical drive and braking unit. This coaxial configuration requires less space. Unit mechanical actuator and the braking unit is placed directly on the rotating shaft levers pedals to further increase the space for use and to maintain balance.

As shown in figure 3 and Figure 4, the drive mechanism 2 includes a rotating shaft 21 (torsion shaft), two pedal lever 22, the side cover 23, block Behnisch drive, the braking block 25, gear 26, the first ratchet 27, the second ratchet 28 and the connecting ring 29.

The rotating shaft 21 is a cylindrical rod.

Each arm 22 of the pedal has one end connected to the far end of the rotating shaft 21, and the other end connected to the pedal. The two ends of the rotating shaft 21 is connected to the two levers 22 pedals, respectively.

The side cover 23 is a circular plate mounted on the rotating shaft 21. The outer part of the side cover 23 is attached to the arm 22 of the pedal, and the inner part of the side cover 23 is equipped with a range of touch plates 231, as shown in Figure 4.

Block 24 mechanical drive, as shown in figure 3 and Figure 5, contains the stator 241 and the rotor 242. The rotor 242 contains a hollow force axis 243 extending from the rotor 242. The rotating shaft 21 is inserted through the force axis 243 unit 24 mechanical drive. One end of the stator 241 is turned to the side of the lid 23. The outer surface of the stator 241 has a touch element 244 to detect the touch plate 231. Block 24 mechanical drive has a circuit connected to an energy saving unit 3.

The braking block 25 shown in Fig.6 and Fig.7, includes a housing 251 mounted on the power axis 243. Many planetary gear 252 is placed in the housing 251 and are located around the power axis 243 so as to engage with the power axis 243. Planetary gear 252 pass through the positioning panel 253 and fixed thereto. Power axis 243 then inserted through the toothed ring 254. One side of the toothed ring 254 has a ring of internal teeth 254 for engagement with the planetary gear 252. The other side of the toothed ring 254 has an output axis 255. The cover 256 is adapted to close the transmission in the housing 251. Cover 256 has a hole for the output axis 255, which passes through it.

A gear wheel 26 mounted on the rotating shaft 21 and has a camera 261 in its Central part, as shown in Figure 4.

The first ratchet 27 consists of part 271 of stop (release) and details 272 clutch. The first ratchet 27 is mounted on the rotary shaft 21 and placed in the chamber 261. Item 271 stop comes in contact (bonded) with the output axis 255, and saralaya part 272 is in contact (bonded) to the inner wall of the chamber 261 so as to transmit power of unilateral rotation.

The second ratchet mechanism 28 consists of details 281 lock (latch) and details 282 clutch. The second ratchet mechanism 28 is mounted on the rotary shaft 21 and is placed in the chamber 261. Saralaya part 282 is in contact (bonded) to the inner wall of the chamber 261 so as to transmit power of unilateral rotation.

Unit mechanical actuator 24 uses electric power from the power saving unit 3 to move the power axis 243. Power axis 243 drives the transfer unit 25 of the braking, and the output axis 255 gives power to the first ratcheting mechanism 27 to rotate the gear wheel 26. At this time, the second ratchet 28 will not result in the movement of the levers 22 of the pedals and the rotating shaft 21. Conversely, when the levers 22 of the pedal pressed to cause the motion of the rotating shaft 21 and the connecting ring 29, the second ratchet 28 will rotate the gear wheel 26. At this time, the first ratchet 27 will not result in the movement of the output axis 255.

Accordingly, the user can select the levers 22 pedals or block 24 mechanical drive as the source of power. They both are driven separately without interfering with each other.

Preferably, the sensor 244 detects the touch plate 231 to measure the speed of rotation of the levers 22 of the pedals. Using the program unit 24 of the mechanical actuator can be activated automatically, for example the EP, when the speed of rotation of the levers 22 of the pedal is low, the block 24 of the mechanical actuator is activated as a source of power. The rotating shaft 21 is installed directly through the block 24 of the mechanical actuator and the braking block 25. This coaxial configuration requires less space and keeps the balance of the bike.

In addition, the braking unit 25 uses many planetary gear 252 to transmit power, distributing strong torsion from the power axis 243, in order to increase the upper limit value of the bearing capacity of the torsion. The present invention provides a stable structure without noise.

Summarizing, we say that the present invention can reduce the configuration space, to keep balance of the bike, increase space, increase service life, and it is noiselessly.
