The invention relates to the manufacture of toys.

The purpose of the invention is to improve ease of operation.

FIG. 1 shows the drive in the off state; general view; in fig. 2 - the same, when working with a small load; in fig. 3 - the same, when working with a large load,

The drive contains an electric motor 2 installed in the housing 1, on the output shaft of which an eccentric 3 sec. Is fixed. groove 4, disk 5, accommodating its impeller with a shank b b of groove 4 with the possibility of movement in it and connected by means of a flexible element 7 to the output shaft 8. The disk 5 is set obliquely at an angle with the possibility of rolling the front surface of the friction surface 1 ten,

The drive works as follows

When the electric motor 2 is turned on, the eccentric 3 with the groove 4 rotates the disk 5 along the tapered path for the shank 6. The resulting centrifugal force deflects the disk 5 from the drive axis by an angle o / and presses the disk 5 to the end friction surface 9 of the housing 1. At This results in running the disk 5 over the surface 9. Without a load, the rotational speed of the engine 2 is maximum, which corresponds to the lowest gear ratio i

: -g (Fig. 2). With increasing on D

the load (moving up the hill) the rotational speed of the drive shaft decreases j reducing the value of D by 4D, thereby increasing the gear ratio i (Fig. 3).

When the disc deviates from the initial position, the flexible element 7 is slightly pulled out, constantly pressing the disc 5 with the surface 10 against the friction surface 9 of the housing 1. The direction of rotation of the driven shaft 8 is in the direction of rotation of the drive shaft (the shaft of the electric motor 2). When it encounters an obstacle, the motor 2 reduces the rotation frequency so much that the deviation of the disk 5 becomes close to the original one, the cohesive force of the surfaces decreases, and slippage occurs. The current consumed is increased, but remains significantly lower than the short-circuit current. When a toy is turned off with the electric motor 2 turned off (FIG, 1), the drive shaft 8 and the disk 5 rotate freely on the incline, on the inertia or on the rope, without interfering with the movement, since there is no centrifugal force pressing the disk 5 to the surface 9 of the housing 1 .

At the time of supplying power to the motor due to the absence of load on its output shaft, an economical power consumption occurs.
