(57) Abstract:

The use of the invention in the transport industry, in the manufacture of sports and road bikes. The essence of the invention that improved speed characteristics, the result of which are improved torque and ensure uniform return crank with pedals for this, parallel to the plane of the sprocket on its axis installed drives. The connecting rods are made in the form of rings with a toothed inner surface, mounted on the frame in bearings. When moving the bike teeth rods are engaged with the grooves of the disks. Rotation of the sprocket is transmitted through the flexible body of the slave drive sprocket of the rear wheel, and the bike moves forward. 2 Il.

The invention relates to the transport industry, in particular, to velotron and can be used in the manufacture of sports and road bikes.

Famous bike Gavrilova, C. M. (see and.with. N 1299891, CL WC/00, 18.03.85), containing frame, handlebar, saddle, pedal drive with the leading and the trailing asterisks covered by the flexible body, the connecting rods with pedals mounted on the axis of the sprocket, and manual Pref is a witch, installed some tips that can be rotated on the axis of rotation and the axis of the sprocket manual actuator mounted on the other end of the thrust made with the possibility of fixing it in two positions, the lever is mounted on the axis of the sprocket, is placed on the outer side of the flexible body of the foot-operated with the opportunity to interact with the flexible body.

The disadvantage of this device is high enough speed, due to the low amount of torque.

Closest to the claimed device according to the totality of symptoms is the bike (see U.S. Pat. RF N 2025385, CL WC/00, 24.10.91) containing a frame with wheels, handlebar, saddle, pedal drive with the leading and the trailing asterisks covered by the flexible body of the actuator, the connecting rods with pedals mounted on the axis of the sprocket, and the P-shaped rod. The bike is equipped with kinematic pair consisting of two equipped with a freewheel clutches stars covered by the flexible body of the gear, and one of the stars of the kinematic pair contains a second number of teeth in contact with the flexible body of the actuator, and the other sprocket of the kinematic pair is connected through a bushing wheel driven sprocket, and the axis of the sprocket.

The disadvantage of this device is high enough speed, due to the low amount of torque.

The basis of the invention is the task of increasing the speed characteristics, the solution of which achieved an increase in torque and providing a uniform return of rods.

The problem is solved in that bike, containing frame, saddle, handlebar, front wheel, rear wheel, foot control with leading and driven sprockets, covered by the flexible body of the actuator, the connecting rods with pedals, sprocket provided with two drives installed parallel to the plane of the sprocket and mounted on its axis, each of the two connecting rods are made in the form of a ring with a toothed inner surface and mounted on the frame in bearings independently of one another, with the possibility of engagement with the grooves of the corresponding disk, the number of teeth of each rod is equal to twice the number of grooves of the disk.

Comparative analysis of the claimed device prototype (U.S. Pat. RF N 2025385) allows us to conclude that the proposed device is different from the known fact that the sprocket drive Snejana two disks, ustinow a ring with a toothed inner surface and is mounted in bearings independently of one another, with the possibility of engagement with the grooves of the corresponding disk, the number of teeth of each rod is equal to twice the number of grooves of the disk.

Thus, the device differs from the known two new elements and their composition that is sufficient to increase torque.

In Fig. 1 presents the proposed bike, General view; Fig. 2 section a-a in Fig. 1.

The bike (Fig. 1,2) contains a frame 1 mounted on her saddle 2, the wheel 3. In the front fork 4 is installed the front wheel 5. Rear wheel 6 mounted on the frame 1. Foot actuator consists of a sprocket 7 and the driven sprocket 8 is covered by the flexible body 9 of the drive. On the axis of the drive sprocket 7 parallel to its plane is equipped with two drive 10,11. The rods 12,13 made in the form of rings with a toothed inner surface and mounted on the frame 1 in bearings independently of one another. The number of teeth of the rod 12,13 equal to twice the number of grooves of the disc 10 and 11. The rods 12,13 attached pedal 14,15 respectively. The axis 16 with the supporting rods to connect seatpost part of the frame 1 with the leading asterisk 7 of the drive can be replaced by a system of bearings.

The device operates as follows.

Use in the inventive bike new elements and their arrangement provides improved speed characteristics of the bike.

The bike contains a frame, saddle, handlebar, front wheel, rear wheel, foot control with leading and driven sprockets, covered by the flexible body of the actuator, the connecting rods with pedals, characterized in that the sprocket drive with two drives installed parallel to the plane of the sprocket and mounted on its axis, each of the two connecting rods are made in the form of a ring with a toothed inner surface and mounted on the frame in bearings independently of one another, with the possibility of engagement with the movement with the slots of the corresponding disk, the number of teeth of each rod is equal to twice the number of grooves of the disk.
