in drives of cars. The aim of the invention is to increase the efficiency of the device, achieved. After the acceleration of the flywheel mass to the required speed, the automatic coupling half 4 connected to the swing mass 5 is disconnected from the leading coupling half 2 of the Uft 3. Disabling the coupling half 2 from the coupling half 4 occurs due to the presence of slanting pshitsy 11, which move the coupling half 2 after the engine 1 is turned off. By the same splines 11, the coupling half 2 moves when the engine 1 is turned on in the opposite direction to engage the coupling 3. Finning 7 increases 3 rodinamicheskoe rotational resistance and promotes the movement of the coupling halves 2 in the axial nap- J / systematic way. 1 il ..

The invention relates to mechanical engineering and can be used in machine drives.

The aim of the invention is to increase the efficiency of the device, due to the fact that when the engine is turned off after accelerating the flywheel masses to the necessary speed, the half coupling connected to the flywheel is automatically disconnected from the coupling half coupling. Thus, the disconnected engine does not slow down the rotation of the flying masses, which increases the efficiency of the device.

The drawing shows the constructs on the scheme of the proposed device. The device for acceleration of the flywheel | masses contains a booster engine 1, | connected to the leading coupling half 2 of the coupling 3, driven by the coupling half 4 which is connected to the flywheel 5, the working face 6 of the driving coupling half 2 is made with radially located tenisy ribs 7, and on the inner, cylindrical surface 8 of the half box 2 and on the outer cylindrical surface 9 of the shaft 10 of the engine 1, the interlocking splines 11 are engaged, the angle of which p is chosen from the ratio

The device works as follows.

When the starting engine 1 is turned on, the leading coupling half 2 is due to

and

torus

its inertia resists rotation and at the same time moves along oblique splines 11 of shaft 10 axially towards the driven half coupling 4. During acceleration of the leading coupling half 2, an additional axial force is directed towards the jamming of the coupling 3 due to aerodynamic resistance to rotation resulting from the presence of a radial finning of the surface 6 of the half-coupling 2 facing the half-coupling 4; As a result of the interaction of the half-couplings 2 and 4, the clutch 3 is wedged and acceleration of the flywheel 5 begins. The jamming of the coupling 5 contributes The vacuum between the coupling halves 2 and 4, resulting from the operation of the open coupling 3 in the mode of a centrifugal pump. When the coupling 3 is closed, the air between the half couplings 2 and 4 is rotated together with the coupling 3 and the aerodynamic resistance caused by the fins is eliminated, which contributes to improving the efficiency of the device. The angle / s of the slot 11 is chosen such that the coupling half 2 can be moved along the shaft 10 of the engine 1.

When the accelerating engine 1 is turned on, its braking torque is applied to the shaft 10. As a result, an axial force arises, which moves the driving coupling half 2 towards the wedging side of the clutch 3. The flywheel 5 and the accelerating engine 1 are disengaged.
