The proposed design of the vehicle consists of a frame 1, a drive wheel 2, the inertial propulsion, drive motor or pedal chain drive, managed by the PE the front or rear wheels with the wheel, the brakes. The frame 1 is welded, tubular cross-section. Drive wheel 2 consists of a rim 3 with the tire 4, the side disks 5 with flanges 6 and bearings 7 and inserted in the slots 5 of the frame 1.

Inertial propulsion consists of a flywheel 8, shaft 9, two-arm pendulum 10, clutch 11. The flywheel 8 includes working body 13 made in the form of thin-walled cylindrical ring, the cross-piece 14 mounted on the shaft 9. The working body 13 is located on the perimeter of the cross-pieces 14 of the flywheel 8, inside the drive wheel 2. Two-arm pendulum 10 one ends on bearings 45 mounted on the axis 16 of the pedal 17, the other end of the pendulum 10 is mounted on bearings 18 of the shaft 9 with the flywheel 8. The pendulum 10 can be rotated about the axis 16 at a small angle and is supported by springs 19 in a suspended position, excluding unauthorized contact with the flywheel 8 with the rim 3, as the axis of the shaft 9 is displaced relative to the axis of the wheel 2.

Foot, muscular drive of the flywheel 8, located on one side of the wheel 2 includes a drive sprocket 20 mounted on the axis 16, a double sprocket 21, located on the finger 22 of the pendulum 10 and the sprocket 23 with the clutch 11 freewheel mounted on the shaft 9, the sprocket pairs are connected by a chain 24.

On the other side of the wheel 2 is the drive wheel 2, which includes the sprocket 25 with the clutch 12 freewheel mounted on the flange is 6 disc 5 of the wheel 2, and the sprocket 26 mounted on the axis 16, the sprocket 25 and 26 are connected by a chain.

The front wheel 27 with the wheel 28 driven, mounted on the rack 29 in the sleeve 30 of the frame 1, or two paired, controlled steering wheel 31 located at the rear of the bike on the axis 32, with a total stand 33 installed in the sleeve 34 on the frame 1, at the front bottom 33 fixed gear sector 35 which engages with the sector gear 36 37 steering, the wheel 37 is mounted in a sleeve 38 on the frame 1.

The drive motor 39 is connected by a chain with a sprocket wheel 26. The seat 41 of the swivel. Brake pad 42 mounted on the finger 43 on the frame 1 near the seat 41 and connected to the lever 44, the braking pad 42 is pressed directly to the tires 4 wheel 2.

Work bike with inertial propulsion. During the rotation of the pedal 17, the force is transmitted through the sprocket 20, 21, 23, the chain 24 and the freewheel 11 on the flywheel 8, at the same time through the sprockets 25 and 26, the chain and freewheel 12, the force is transmitted to the wheel 2, as a result, the bike moves and spins the flywheel 8, which stores kinetic energy moment of inertia of rotation of the working fluid 13.

Clicking on the pendulum last 10 together with the rotating flywheel 8 is rotated by a small angle ϕ (Fig. 5-7), periodically, for a short period of time presses the perimeter of the working body 13 of the flywheel 8 to the inner surface the STI rim 3 of the wheel 2 at point a (line AA), the contact surfaces of the working fluid 13 and the rim 3 is covered with a friction composition, some of the kinetic energy is transferred to the rim 3 of the wheel 2, a force P of the reaction rim 3, the force Rdthe translational motion of the flywheel 8.

In addition, during the period of contact of the flywheel 8 with the rim 3 of the wheel 2 at point a (line AA) the velocity of the mass point of the working fluid 13 is changed and the line of contact AA occurs instantaneous center of rotation (MCV) of the working fluid 13, the speed MCV equal to zero, at this moment appears the moment of force M mass mcp working medium 13 on the shoulder of the instantaneous radius R relative to MCV, the moment of force M force also causes Pmthe translational motion of the flywheel 8. As a result, the Bicycle from the flywheel 8 is affected by two forces translational motion:

a) the power of the Pdthe moment of inertia of the rotation operating body 13 of the flywheel 8,

T=J·ω2·1/2where T is the kinetic energy of rotation of the working fluid 13,

a J=m·r2where J is the moment of inertia of the working fluid 13 (kg,·m2), m is the mass of the working fluid 13, r is the radius of the working fluid 13, ω - the angular velocity of the working fluid 13;

b) the moment of force M mass mcp working body 13 of the flywheel 8 is relatively MZW,

and M=mcp·R, where M is the torque mass mcp working body 13 relative to MCV; mcp - mass part of the working fluid 13, which RA is placed above the horizontal diameter; R is the instantaneous average radius of a working body 13 when the rotation operating body 13 relative to MCV.

When the mass m of the working fluid 5 kg and 2000 rpm (40000 rad / sec) of the working fluid 13 and its radius r is equal to 0.3 m, the kinetic energy T=9000 kg·m2·happy·s2.

When the rotation of a rigid body around an axis plays the role of mass moment of inertia. During the movement of the bike, the power consumption will be about 3 KGM per second, which will ensure the speed of the bike at least 50 km/h for 150 seconds without recharging (unwinding) of the working fluid 13. During this time we will spend about 50% of the maximum kinetic energy. Charge (spin) of the flywheel 8 with the working fluid 13 to the calculated value of the speed will take a few seconds. The period of contact of the working fluid 13 of the flywheel 8 with the rim 3 of the wheel 2 is equal to 4-6 seconds at intervals of 8-10 seconds.
