The invention relates to mechanical engineering and can be used in the entertainment industry to create vehicles with new consumer properties.

Known vehicle, such as a "Volkswagen Touran", which for speed control are used pedals: clutch, throttle, brake and gear lever (magazine "Behind the wheel" No. 11, 2002, p.102).

The disadvantage of this vehicle is a step change of gear ratio.

The closest in technical essence and the achieved result is a vehicle, for example, "Honda Jazz", which uses an automatic stepless transmission - CVT (magazine "Behind the wheel" No. 11, 2002, p.97).

A disadvantage of the known vehicles is a significant amount of time required for switching from a forward stroke on the back and back, and also indirectly by controlling the speed of rotation of the driving wheels of the vehicle and a low range gear ratio.

The objective of the invention is to provide a vehicle with new consumer properties, which control the speed is continuously variable with a wide range of gear ratio and minimized the time of the change forward stroke on the back and back.

This set of features is new and involves an inventive step, since the use of the amplifier, such as mechanical, as the variator allows you to change the speed in a wide range, to minimize the time of the change forward stroke on the back, because the presence of the control differential amplifier allows you to change the speed of the leading elements effect mechanisms. Governing differential synchronizes the rotation speed of the leading elements effect mechanisms with the speed of rotation of the slave units effect mechanisms. Effect mechanisms operate in the mode of release, acting as mechanical amplifiers when the host link runs away from rolling his slave link, setting the speed of rotation of the latter. The closer the effect of the mechanism is made to the border of the automatic braking, the less force is needed to control the amplifier and the correspondingly higher gain.(A.A. Blagonravov Mechanical stepless preacidification type. - M.: Mashinostroenie, 1977, p.59). The power differential distributes the momentum supplied to it from the engine, between the main wheels of the differential comparison. The differential comparison, depending on the difference in speeds of rotation of the Central wheel, rotates the output level of the amplifier with a certain velocity. The greater the difference in speeds of rotation of the Central wheel differential comparison, the faster it rotates the output level of the amplifier. The leveling mechanism of the speed of rotation of the Central wheel governing differential equalizes the speed of their rotation in the absence of control action, and the presence of the pedal Board Bicycle type allows you to control the amplifier.

The drawing shows a diagram of a vehicle.

The vehicle includes a motor 47, the pedal unit 46 and mechanical power.

The mechanical amplifier consists of:

the power differential 1 with the Central wheels 17, 18, 24 satellites and power input 22;

governing differential 2 with the Central wheels 19, 20, 25 satellites and gear 23;

differential comparison 30 with the Central wheels 32, 33, 35 satellites and the output level of the amplifier 34;

the governing differential 36 with the Central wheels 42, 43, 44 satellites and the control input of the amplifier 45;

effect fur the isms 3 and 4, each of them consists of slave units 15, 16 and the leading elements 13, 14;

the power input of the amplifier 21;

gears 5, 6, 7, 8, 9, 10, 11, 12, 26, 27, 28, 29, 31, 37, 38, 39, 40;

leveling mechanism of the speed of rotation of the Central wheel 41.

When this control input 45 of the amplifier is connected to a pedal Bicycle type 46, the output link 34 of the amplifier is connected to driving wheels (in the drawing not shown), and power input 21 of the amplifier is connected to the traction motor 47, operating at constant speed.

While the input of the power differential 22 is connected to the traction motor 47 and the input 23 of the governing differential 2, the Central wheels 17 and 18 of the power differential 1 are rigidly connected to slave units 15 and 16 effect mechanisms 3 and 4 and connected with the Central wheels 32 and 33 of the differential comparison 30 so that the Central wheels 32 and 33 of the differential comparison 30 rotate in opposite directions. Leading the links 13 and 14 effect mechanisms 3 and 4 are connected with the Central wheels 19 and 20 of the governing differential 2 and the Central wheels 42 and 43 of the control differential gear 36 so that the Central wheel 42 and 43 of the control differential gear 36 is rotated in opposite directions. The Central wheels 19 and 20 of the governing differential 2 shorted mechanism alignment soon the TEI of rotation 41.

The vehicle operates as follows. The power input of the amplifier 21 is rotated at a constant speed from the motor 47. Thus in the strength of the kinematic chain 21-22-24-18-26-28-32-35 rotation is transmitted to the satellite 35 differential 30. According to another power kinematic chain 21-24-17-27-29-31-33-35 rotation is transmitted on the same satellite 35. Thus rotation of the Central wheel 32 and 33 of the differential 30 is at the same speed and in opposite directions, the output level of the amplifier 34 remains stationary. Concurrently, the governing kinematic chain 21-23-25-20-12-10-14 rotation is transmitted to the host link 14 effect mechanism 4 through gears 38, 40 on the mechanism of equalization of speeds of 41, and through gears 6 and 8 on the Central wheel 42 of the governing differential 36. On the other governing kinematic chain 21-23-25-19-11-9-13 rotation is transmitted to the host link 13 effect mechanism 3 through gears 37 and 39 on the mechanism of equalization of speeds of 41, and through gears 5 and 7 on the Central wheel 43 of the governing differential 36. Central wheel all differentials rotate with equal pairwise velocities, while the Central wheels 32 and 33 of the differential gear 30 rotate in opposite directions and the output level of the amplifier 34 is stationary. Central wheel 42 and 43 of the governing differential 6 is also rotated in opposite directions, and the input of the amplifier 45 is stationary. Thus, the entire mechanism is in equilibrium, and leading the links 13 and 14 effect mechanisms operating in mode release time to escape from rolling them slave units 15 and 16. The vehicle is in place, i.e. at zero speed.

During the rotation of the pedal unit 46 starts to rotate kinematically connected therewith, the input of the amplifier 45, the speed of rotation of the Central wheel 42 of the differential 36 is reduced, and the Central wheel 43 is increased. Since the Central wheel 42 on the above kinematic chains connected with the driving member 14 effect mechanism 4 and the Central wheel 20 of the differential 2, and they reduce the speed of rotation. Slave link 16 effect mechanism 4 mode release, relying on the leading link 14 will also reduce the speed of rotation, in the end decrease the speed of rotation of the Central wheel 18 and 32 differentials 1 and 30, connected with the slave link 16. All differentials will be a redistribution of momentum between the Central wheels. The speed of rotation of the Central wheel 43, 19, 17 and 33 will increase proportionally, and leading link 13 effect of the mechanism 3 mode release, manages to escape from the incident on his slave link 15, not ostava obstacles to its rotation. Since the Central wheels 32 and 33 of the differential 30 to get a different speed, the output level of the amplifier 34 will start to rotate. When the rotation angle and the rotation speed of the output link 34 is proportional to the rotation angle and the rotation speed of the pedal unit 46. During the rotation of the pedal unit 46 in the opposite direction of the output link 34 will also change the direction of rotation. The mechanism of alignment of the rotation speeds of 41 in the absence of effects on the pedal block 46 aligns the speed of rotation of the Central wheel 19 and 20 of the differential 2, setting zero speed output link 34.

Thus, this invention allows to create a vehicle with new consumer properties, reduce the time of the change forward stroke on the back and back and extend the range of change of gear ratio.
