The essence of a bike, containing the axes of the inner and outer pairs of gearing leading and trailing elements, equipped with a centrifugal element, a flexible coupling, the spring-loaded leashes and the coupling sleeve, and a spring-loaded leash outer pair of engagement with a flexible coupling is connected with the centrifugal element made with the possibility of axial movement and periodic interaction with the coupling having a sloping ledges, rotating and constant interaction with sloping depressions coupling, which is limited in the axial offset and movably connected with the coupling, occasionally interacting with the inner pair of engagement. 3 Il.

The invention relates to the bikes used for racing at the time and in the mountains.

Famous racing bike, containing a frame with two wheels, drive sprocket, an endless chain and block the slave sprocket and the mechanism of translation chain bike (application France N 2483349, CL 62 To 3/00, 1981).

However, the famous racing bike, accepted as a counterpart, the shifting is carried out manually. When Effektivnosti biological engine. Tedious to repeatedly shift the gear in a fast-changing terrain. Varying the parameters of the transmission during the race is not always possible. For example, during track racing gear is prohibited; distraction hands on switching affects the balance of the rider and may result in falling or accidental interference rivals. It is difficult to simultaneously switch arms transfer and, without missing a pace, spin the pedals. It is difficult to capture the best moment of switching in a rapidly changing environment. The shifter element of reduced reliability. The reliability decreases when the input links of the chain engages with the sprocket teeth of the ratchet. When a pedal effort for in full at the time of switching may out chain.

There are a number of constructive solutions of the shifter, excluding jumping circuit, that is more reliable, containing the planetary gear, the axis of which is built plunger communicating via a lever and a flexible connection with the manually operated switch (patent England N 2186515, CL 62 11/16, 1986).

A disadvantage of the known analogues is the difficulty to capture the best moment is Noah transmission. It is difficult to simultaneously switch arms transfer and, without missing a pace, spin the pedals.

Known automatic planetary transmission for a Bicycle containing the rear axle, gear, two of the connecting rod on subcateg and shaft (application Germany N 3444140, CL 62 M 11/14, 1986).

The disadvantage of analog is the need to change the direction of rotation of the rods, therefore, violated customary and coordinated work of the muscles. Shift work the muscles in the opposite equivalent failure of biodigital.

Also known two-stage transmission for a Bicycle that contains an asterisk, covering the circuit, the switching mechanism is placed on the axis of the rear wheels, and control elements in the form of sleeves with scalloped surfaces (ed. St. N 768691, CL 62 M 9/06, 1980).

A disadvantage of the known transmission-analogue, is the need to pedal backwards when each of the switches. Break the rhythm of the movement, because at this point the muscle energy is spent overcoming the distance, which affects the results in.

Known chain drive allows you to automatically change the gear ratio depending on the load, containing elastic elements, the hooks of the device is similar to the sharpness of the work, the movement is accompanied by severe tremors that occur due to the gathering chain link free branch with a hook on the deformed elastic element. Each change of gear ratio is also associated with push. A smooth variation of the diameter of rotation of the hooks is not possible, and the distance between the hooks located at the connection cannot be changed, so that the chain is practically not stretched, and discrete.

Closest to the proposed technical solution is the bike on the rear axle which is installed with the inner and outer pairs of gear wheels and a switching mechanism of the latter, and a manual drive mechanism switch is located on the frame of the bike (UK application N 2166502, CL 62 11/16, 1986).

A disadvantage of the known technical solutions adopted for the prototype, is the need for constant surveillance of the correctness of the transmission. It is difficult to capture the best moment to switch, which is manually operated. It is difficult to simultaneously switch arms transfer and, without missing a rate of movement, to turn the pedals. Multiple shifting at a quickly changing situation and the terrain slopes tiring. the provisions of comfortable conditions by instant, multiple forward and reverse automatic multistage switching speeds depending on the conditions on the road race without the intervention of the cyclist, while maintaining high reliability and safety, as well as providing a simple, smooth and accurate installation of each of the speeds at which switching occurs without the influence of the cyclist, there is an automatic switch.

This goal is achieved by bike "Anna", the axes of which installed the system with the inner and outer pairs of engagement with the drive from the driving element, which, according to the invention, equipped with spring-loaded leashes, centrifugal element and system gear couplings, while the leading element is made with the possibility of advanced gear on the clutch inner pair, and the system spring leashes and gear couplings are made with the possibility of a delay in the transmission torque of the outer pair to stop transmission of the torque of the inner pair of gears, centrifugal mechanism configured to interact with a spring-loaded leash. In the presented set of features taken separately required, and all together are in funcallable General view of the Bicycle "Anna"; in Fig.2 and 3 mechanisms of automatic switching section.

Bike "Annushka" contains three versions of the automatic gearshift, which are connected by the endless chain. Each option provides instant forward and reverse automatic gear change with every change of speed. The rate at which each switch, adjustable, set at the request of cyclist. The first option presents a cross-section a-a (Fig.1 and 2), in which the leading element of the sprocket 1 and the slave the rear wheel hub 2. The fixed element is the axis of the rear wheels 3, which is fixed relative to the Bicycle frame 4. The second option presents a section b-B (Fig.1 and 3), in which the leading element is the axis of the driving rods 5, the slave sprocket 6 and the fixed housing, aka the bike frame 4. The interaction between the two options provides multiple switches.

In the first scenario: on the axis of the rear wheels 3 posted by fixed gear coupling half 7 and a movable toothed coupling half 8. The coupling halves 7 and 8 are made with the possibility of periodic engagement. The coupling element 8 is the internal p is elite coupled with the rear wheel hub 2, which is an element of the outer pair of engagement. On the sprocket is movable with the possibility of longitudinal movement mounted leash 10. The leash 10 is spring-loaded by a spring 11 and is connected by a flexible connection with the centrifugal element 12, which is made in the form of weights, is installed, for example, in the bore of the sprocket 1. The leash 10 includes a serrated edge and is made with the possibility of periodic engagement with the toothed coupling half 13. Toothed coupling half 13 movably mounted in the rear wheel hub and has a possibility of rotation. The coupling 13 has a helical edge with the angle of the teeth 45about. The coupling 13 is coupled with helical slotted end of the lead 14, which is placed in the slots of the sleeve of the rear wheels 2. Slotted lead 14 and a movable toothed coupling half 8 is spring-loaded by a spring 15. Spring 11 benevolen adjusting screw 16.

Option two: on the axis of the driving rods 5 by means of the overrunning clutch mounted sun gear 17, which is coupled with the satellite 18. The gear 17 and 18 satellites are elements of the inner pair of engagement. On the sun gear 17 adjustably mounted gear half coupling 19, which is continuously connected with the sun gear, however, has the ability prodolgovatoe the coupling 19. The satellites 18 are mounted on a drive rod, which is driven sprocket 6. The satellites 18 and connected with the gear coupling 21. Gear coupling 21 and 17 satellites elements of the outer pair of engagement. Gear coupling 21 is installed movably in the bore of the frame 4 has a possibility of rotation and longitudinal displacement along the bore. On the gear coupling 21 rotatably mounted to the lever 22. At the same time the lever 22 connected with the sprocket 6, which has a relatively longitudinal movement and is spring-loaded by a spring 23. The lever 22 is connected by a flexible connection with the centrifugal element, which is mounted on the sprocket 6. Gear coupling 21 is made with the possibility of periodic clutch with gear coupling 25 available at the ends of the teeth. Gear coupling 25 is installed in the bore of the frame 4 rotatably and contains a helical edge, which coupled with the helical slotted end of the leash 26. Slotted lead 26 is placed in the slotted area of the bore of the frame 4. Slotted lead 26 and the gear half coupling 19 is spring-loaded by a spring 27. The spring 23 benevolen adjusting screw 28. The adjusting screw 28 is placed in the sprocket 6.

Bike "Annushka" provides automatic switching in zawisimomu wheel is necessary to bring the greatest torque. This requirement is fully implemented by bike "Anna", while effectively used bioenergy racer, because all the mechanisms of the bike are in position "downshift". In Fig. 3 shows the mechanism of the hub in position "downshift". The rider rotates the pedals, while rotating axis of the drive rods in the forward direction. The overrunning clutch that is installed on the axis of the driving rods 5, is closed and transmits the torque of the sun gear 17, i.e., the internal element of the pair of engagement. Rotate the satellites 18 and carrier, i.e., the driven sprocket 6. However, the toothed coupling element of the outer pair of gear 21 does not rotate due to the coupling with the gear coupling 25. From the transmitted torque gear coupling 25 is rotated around its axis to another in a helical slotted end of the lead 6. Due to the axial component from the interaction of the helical ends, slotted lead 26 is shifted along the slots in the bore of the frame 4 in the extreme position to another. If shifted slotted leash 26, the compressed spring 27 and open the teeth of the coupling 19 with the toothed end of the sprocket 6. Gear coupling 21 is held in this position by the spring 23 through the lever 22. Described you the second sprocket 6 with a stationary gear of the coupling 21. Once the bike gained speed, a switchover occurs, in which the driver without increasing cadence increases the speed three times. The required speed limit, when this switch installs the driver himself preliminary adjustment screw 28.

This switch is as follows. When moving the bike by inertia even when you stop pedaling driven sprocket 6 is rotated. This rotation of the overrunning clutch is provided, which is installed between the axis 5 and the sun gear 17. The supply mechanism of the hub freewheel distinguishes the proposed design of the bike from the famous. Different proposed design of the bike from the known technical solutions and also the fact that when the bike is coasting on inertia, when the cyclist has stopped pedaling, all stars rotate, i.e., rotates the driven sprocket 6 and the sprocket 1. Speed clearly tracked rotary element 24, which is embedded in the driven sprocket 6. Centrifugal element through a flexible connection acts on the lever 22, causing the compressed spring 23. Leash shifts the gear coupling 21, and outputs p 26. Slotted leash together with the toothed coupling half 19 are shifted by the spring 27. Shifting gear half coupling 19 is closed by the toothed end of the driven sprocket 6 and the sun gear 17. Thus driven sprocket 6 and the sun gear 17 to rotate together as a unit. Produced a twofold increase in the ratio is not all. The pedaling frequency, and speed continue to increase. Of course, I want uphill or on a very good path to go even faster. But very quickly on a conventional bike legs do not have time to spin. However, the proposed bike such a terrible problem takes. Automatically and instantly, without increasing cadence twice the speed increases, i.e., the following occurs twofold increase of gear ratio, which in General result is four. This switching mechanism is provided, which is integrated into the rear wheel hub 2. Centrifugal element clearly monitors installed by the rider shifting, which is set by the adjusting screw 16 on request before arrival. Just this provision corresponds to section (Fig.2). The spring 11 is compressed, as podvodka 10 is released from engagement with the toothed coupling half 13. Toothed coupling half 13 unfolds in its original position. Released pressure gear coupling 13 on helical slotted end of the leash 14. Slotted leash together with the gear coupling 8 under the action of the spring 15 are shifted. Movable toothed coupling half 8 engages with a stationary toothed coupling half. Thus the movable toothed coupling half 8 relative to the axis of the rear wheel 3 is fixed, and the rear wheel hub 2 and the wheel itself makes two turns around its axis during one revolution of the sprocket 1.

As soon as the speed decreased, for example, when climbing slopes or loose surfaces, the opposite happens, the automatic gear shift in reverse order of interaction elements. With a slight decrease speed switching will occur in the rear wheel hub. This will allow, without slowing the pace of pedaling, increase applied to the rear wheel torque twice. If the track is going to change significantly, then there occurs a steep slope or viscous soil, and the rate continues to fall instantly in the hub, this will happen automatically switch. Same thing, at the moment of launch. The torque supplied to the rear wheel, howling rivals, pulling the bikes themselves. As soon as improving the route, automatically increases the speed, which is immediately accompanied by an increase in gear ratio in the mechanisms of the hub and the rear wheel. Any of the switches is not accompanied by tremors and shocks. Circuit switching transmission is not transmitted, and therefore, increases the safety and comfort of driving. When you stop pedaling and the movement of the Bicycle free-wheel mechanisms are not returned to its original position and remain in that position, which is determined by the speed of movement. Such mechanisms eliminates excessively frequent switching. The sequence of actuation mechanism of the hub and mechanism of the rear wheels between them can be changed at the request of cyclist and is determined by the setting of the adjusting screws 28 and 16.

Bike "Anna" will provide the best way to implement bioenergy racer. This eliminates the concern about the gear that automatically, instantly with every change on the track. However, eliminates unnecessary switching in the time of the termination of pedaling and the bike is moving the tumbler. Switching without noise and tremors, hair is ASTA and precise setting of the time switch, which is set in advance according to the request of the driver, no external characteristics that distinguish the bike from the track, it all essentially allocates the bike system "Annushka" over known. According to preliminary calculations, the introduction of a Bicycle "Anna" will bring a huge income.

Bike, containing the drive with variable transmission ratio, the axes of which has inner and outer pairs of gearing leading and trailing elements, characterized in that it is equipped with a centrifugal element, a flexible coupling, the spring-loaded leashes and the coupling sleeve, and a spring-loaded leash outer pair of engagement with a flexible coupling is connected with the centrifugal element made with the possibility of axial displacement and periodic interaction with the coupling having a sloping ledges, rotating and constant interaction with sloping depressions coupling, which is limited in the axial offset and movably connected with the coupling, occasionally interacting with the inner pair of engagement.
