Bike - individual two-wheeled vehicle driven by the efforts of the legs through the pedals to the rear wheel.

The invention relates to the field of engineering vehicles.

Known bike, patent RU 2329912 containing the frame with the wheel, leading and steering wheel, pedal chain drive, lack of which is the need for constant maintenance, adjustment, chain tension, as well as escaping the chain from the sprocket.

Known bike, patent RU 2146632 containing the frame with the wheel, leading and steering wheel, pedal drive with pedals, pivotally connected to the frame and covering the bearings attached to the leading wheel eccentric and diametrically opposed relative to the axis of the wheel. The disadvantage of the design is the constant kinematic relationship of the rotating wheel with pedals, i.e. when moving the bike pedals are always in motion, which makes it impossible for the rest of the legs, and found use as a transport.

The purpose of the invention is to eliminate the chain transmission, as well as to exclude the constant kinematic relationship pedals with the sprocket wheel.

The objective is achieved through the transfer of effort on the pedals to the drive wheel through a gear and clutch one-way rotation.

In the first embodiment, the left and right pedals are not dependent among themselves, what they can be in action, and the peace of mind when driving the bike, and at the same time and separately.

The second option saved usual circular and interdependent relationship pedals.

The invention is in the center of the drive wheel is mounted two-way clutch one-way rotation with bilateral gear pedal to the clutch.

In the first embodiment, the gear consists of a gear sector on the opposite end of the pedal arm with its axis of swing, the intermediate gear with the axis of rotation on the frame and gear acting on the outer roller clutch one-way rotation.

Installed and the spring return movement of each pedal, and the straps on the pedals, as well as the bounding box of the movement of the pedal levers mounted on the frame and fastened together in the bottom part.

Pumping action of the right and left pedals are independent of one another.

In the second embodiment, the gear consists of a gear, with the axis of rotation on the outer pedal lever meshing on one side with an arcuate gear rack mounted on the frame, and on the other hand - with the gear acting on the outer roller clutch one-way rotation.

Each pedal lever sliding inner frame shape in longitudinal section, connected to the pedal in a circular rotation, and the outside is th, the box-shaped form in cross its cross section has an axis of swing on the axis of the drive wheel with roller bearings.

Section B-C.

A bike with a swinging movement of the pedal includes a frame 1 with the wheel 2, the drive wheel 3, the steering wheel 4, the two-way clutch 5 one-way rotation, gear intermediate gear 6, the pedal 7.

The second option is a Bicycle with a circular rotation of the pedals contains similar device.

Distinctive features when describing the operation of the device.

The device according to the first embodiment is as follows. When you press the pedal 7 of the toothed sector 8 will transmit the force and rotates the intermediate gear 6 and the gear 9, which is rigidly mounted on the outer cushion clip 10 of the coupling 5. During rotation of the cage 10, the rollers 11 will jam the clip 10 with the rim 12, which is the Central part of the wheel 3, and wheel the Udet to rotate in a clockwise direction.

Upon termination of the force on the pedal 7 of the last stops or rotates in the opposite direction under the action of the spring 13, the clip 10 will also stop or, respectively, will rotate in the opposite direction, and the contact surfaces of the rim 12 and the shell 10 will displace the rollers 11 in their grooves 14. When the wheel 3 with the rim 12 can continue rotating in the same direction, and the yoke 10 with an associated through the transmission gear pedal 7 can be stationary or moving in the direction opposite to the initial direction.

The action of the pedal 7 to the right and left independent of one another.

Instead of the spring 13, or for joint action, perhaps the use of straps 15 pedal 7, in the likeness of the ski.

Braking is known braking devices with manual levers 16 at the helm 2.

To limit the movement of the pedal levers in horizontal and vertical directions are set frame 17, fixed to the frame 1, and in the bottom part fastened together.

Changing the ratio of the radii of the gears is the selection of the optimal effort on the pedals for each destination of the bike and on both options.

Work on the second version. When you press the pedal the last 18 will rotate around its axis, mounted on the frame 19, and at the same time telescopescience 20 and 21 will swing on the axis of the drive wheel 22, and the gear 23 having an axis of rotation on the lever 21 and in engagement with the arcuate gear rack 24 will rotate in a counterclockwise direction. On the other hand, the gear 23 being in engagement with the gear 25, is rigidly installed on the protruding outer roller cage 26 coupling 27 will cause rotation of the gear 25 and the shell 26 in a clockwise direction. When turning the clip 26, the rollers 28 will jam the clip 26 with the rim 29, which is the Central part of the wheel 22 and the wheel will rotate in a clockwise direction.

Upon termination of the force on the pedal 18 last stop and stop ferrule 26. Rotating the rim 29 to displace the rollers 28 in their grooves, similar to figure 3 of the first variant, and the wheel 22 with its rim 29 will rotate, and the yoke 26 and the pedal 18 can be stationary relative to the wheel.

The master lever 20 moves within the box-shaped lever 21 roller 30 in the lower part of the lever 21. The gear 23 on the axis of rotation has a roller bearing 31.

Action pedal 18 to the right and left are interrelated and are identical.

Braking is also known braking devices on the master and the steering wheel 22 and 32 with hand levers 33 34 steering.

1. The bike contains a frame with the wheel, leading and steering wheel, pedal drive circular rotation braking device with manual exposure, bilateral is the UDF unilateral rotation in the hub of the drive wheel, bilateral gear, wherein each gear comprises gear with the axis of rotation on the outer pedal lever meshing on one side with an arcuate gear rack mounted on the frame, and on the other hand - with the gear acting on the outer roller clutch one-way rotation.

2. The Bicycle according to claim 1, characterized in that the pedal levers telescopic inner has a frame shape in longitudinal section, and outer box-like shape in cross section with the axis of swing on the axis of the drive wheel and bearing.
