Description

FIELD OF THE INVENTION The invention relates to vehicles driven by human muscular strength, in particular power transmissions of bicycles.

The aim of the invention is to simplify j the construction of a bicycle.

FIG. 1 shows the drive, general view; in fig. 2 - its location on the bike.

On the frame 1 of the bicycle (two or three-wheeled) are fixed carriages 2 and 3 of the foot Yu and manual drive. On the carriage 2, the leading sprocket 4 is installed with the flaps 5 rotated in one direction, connected to

the clutch on the sprocket 7, the chain 6 freely turns the sprocket 7 clockwise. A cycle of idling takes place, which takes 0.7-1 s, then the cyclist begins to push the legs 5 with both feet, but with his hands and arms to the lever 10, I will act through both sprockets 4 and 9 and chain 6 on the sprocket 7. The overrunning clutch turns on and the drive wheel 8 pushes the bike forward.

Duty cycle occurs within 2-3 seconds. During all the cycles, the cyclist maintains the balance and direction of motion, turning the front wheel 13 over the steering wheel 11 and the cables 12. During the working chain 6, thrown over the driven

sprocket 7 of the rear wheel 8. On the carriage 3 of which the cycle includes an asterisk 9, which is connected to the lever, the back, both arms and legs at the angle

10 hand drive. One end of chain 6

mounted on an asterisk 9, and the other on

asterisk 4.

The outer diameters of the stars 4 and 9 are mates. On the lever 10, a steering wheel 11, 20 is connected by cables 12 with a front wheel 13.

The transmission works as follows to drive the leading sprockets to 130 °, which dramatically increases the drive power.

Claims (1)

Invention Formula A bicycle containing a frame, wheels, a foot drive, having a drive and driven sprocket, covered by a flexible organ, pedal levers mounted on the axis of the drive sprocket with the possibility of reciprocating motion, a manual drive having a sprocket mounted on the side opposite to the leading gear sprockets of a foot drive, levers mounted on the axis of a manual sprocket with the possibility of reciprocating motion, characterized in that, in order to simplify the design, the flexible member is open m, one end is fixed to the hand drive sprocket and the other - on the drive sprocket foot drive. 30 m. The cyclist, grouping, presses to himself and stretches his arms forward, acts on the steering wheel 11, and turns the lever 10 counterclockwise. At the same time the press muscles work. In the place of conjugation of sprockets 9 and 4, where the flexible chain is clamped and has only one degree of freedom, the asterisk 9 transmits the torque to the sprocket 4, like a flexible insoluble wire placed inside the spring, is capable of transmitting not only pushing effort. Thanks to the overrun the clutch on the sprocket 7, the chain 6 freely turns the sprocket 7 clockwise. A cycle of idling takes place, which takes 0.7-1 s, then the cyclist begins to push the legs 5 with both feet, but with his hands and arms to the lever 10, I will act through both sprockets 4 and 9 and chain 6 on the sprocket 7. The overrunning clutch turns on and the drive wheel 8 pushes the bike forward. Duty cycle occurs within 2-3 seconds. During all the cycles, the cyclist maintains the balance and direction of movement by turning the front wheel 13 through the steering wheel 11 and the cables 12. The muscles of the back, both arms and legs are rotated at an angle turn the leading sprockets to 130 °, which dramatically increases the drive power. Invention Formula 0 five 0 A bicycle containing a frame, wheels, a foot drive, having a drive and driven sprocket, covered by a flexible organ, pedal levers mounted on the axis of the drive sprocket with the possibility of reciprocating motion, a manual drive having a sprocket mounted on the side opposite to the leading gear sprockets of a foot drive, levers mounted on the axis of a manual sprocket with the possibility of reciprocating motion, characterized in that, in order to simplify the design, the flexible member is open m, one end is fixed to the hand drive sprocket and the other - on the drive sprocket foot drive.
