The method relates to mechanical engineering, in particular to mechanical transmission.

Known way to drive a Bicycle, consisting in the use of unilateral transfer of rotation from a closed flexible coupling, representing virtually closed circuit envelope two stars. (EN 2000244, B 62 M 1/04, 07.09.93). The disadvantage of this method at low speeds the bike. This method is adopted for the prototype.

The purpose of this method is the increased efficiency and enhanced operational capabilities drive the bike.

The essence of the way of the drive of the bike is that the bike lead alternate coz the supports, located on the branches of the transmission.

The method explains the drawing, where indicated:

1 - flexible closed the connection transmission one-way rotation;

2 - support;

3 - the control device;

4 - send one-way rotation with the other side of the bike;

5 - wheel.

The drive wheel 5 includes two coaxial transmission 1 and 4 one-way rotation of the flexible closed the connection located on both sides of the bike. On the branches of the transmission 1 is bearing 2 with four rollers in a common rigid cage. The control device 3 in turn consistently Flex branch transmission 1, interacting rollers with the rollers of the cage. Movement up corresponds to the rotation of the gear 1 in the direction indicated by a solid arrow, and the left rotation of the pulley together with the wheel. Movement of the adjusting device down causes the rotation of the right pulley transmission 1 and the rotation transmission 4 with the wheel.

Thus, sequential elongation of the branches of the transmission 1 flexible coupling is transmitted to the wheel.

The elongation depends on the magnitude of motion of the pressure device and the number of cooperating rollers. The amount of traction the number of rollers AET Cycling with greater speed, than by known methods.

The method can be used to extend the operational capabilities of the transmission with a flexible coupling.

1. The way of the drive of a Bicycle transmission unilateral rotation closed with a flexible coupling, wherein the lead alternating agreed bending branches transmission.

2. The method according to p. 1, characterized in that the lead bending branches by their interaction with supports arranged on the branches of the transmission.
