Description

Shaft 7 is rigidly connected with an asterisk l8 of the freewheel. The outer race 19 of the freewheel via finger 20 is connected to the fixed housing 21,

On the sprocket 18 there is a bracket 22, in which a double-arm lever 24 is pivotally mounted on the axis 23. With one roller equipped with a roller 25, the lever 24 interacts with the disk 11 and the second shoulder with the disk 26 having a groove 27. The disk 26 is connected with an asterisk 18 an elastic element 28, which can be, for example, a torsion spring of any type. Lever 24. podzhat spring 29 to one of the walls of the groove 27.

External independent drive 30 through the roller., 31 can interact with the disk 11, moving it to the left end position or

completely free. An output shaft 32 is connected to the disc 26 of the proposed clutch. The proposed clutch operates as follows.

If the external drive 30 with the roller 31 is retracted from the disk 11 and the half coupling 4 is covered with tension by the spring 5, then when the input shaft rotates, the parts 3,5,6,8,11, 12; 13,14,17, and also the parts 4,7,18, 22,23,24,25,28,26 and 32, since during rotation of the leading coupling half 3, the spring 5 is self-engaging on the driven coupling half 4 and the latter receives rotation in the same direction, and the driving shaft. i If any external resistance is applied to the output shaft 32, the disk 26 will begin to lag behind the sprocket 18 of the overrunning clutch, and the elastic element 28 will begin to deform. If resistance is on

to the driven shaft 3.2 exceeds the allowable one, then the lag of the disk 26 from the sprocket 18 will reach such a value that the lever is. under the influence of one of the walls of the groove 27, the roller 25 presses the disk 11 and through the finger 10 on the lever 14. In this case, the lever 14, turning around the axis 13, with its shoulder 15 rotates the disk 6 on the shaft 7 to the position in which the spring 5 encompassing This, however, driven half coupling 4, unwinds in the opposite direction of pressure, its internal diameter will increase and spring 5 will release the driven coupling half. As a result, the driven coupling coupling 4 will be disconnected from the driving coupling 3.

However, the torque stored by the elastic element 28 will continue to act on the disk 26 and the shaft 32, since even after disconnecting the driven coupling half 4 from the driving 3 freewheel clutch will not allow the elastic element 28 to communicate the torque

moment by turning the asterisk 18 in the opposite direction. This is prevented by the connection of the outer race 19 of the one-way clutch with the fixed case 21.

The input shaft 1 will not be connected to the shaft 32 all the time. While under the influence of the moment created by the elastic element 28, the disk 26 does not rotate by some amount at which the lever 24 under the influence of the springs 29 and 17 can turn on

The ANGLE at which the disk 6, having turned on the shaft 7, then there is no spring 5 on the driven half coupling 4 and the input shaft 1 will again be connected with the driven parts. Spring element again

will begin to deform.

The proposed coupling may be included at any time (i.e., regardless of the amount of insertion of the elastic element 28) using

0 of the external drive 30. Moreover, if the roller 31 interacts with the disk 11 prior to the start of rotation of the input shaft 1, then the coupling half 4 and all the associated children will be aware

they are disconnected from the leading coupling half 3, because under the influence of the finger 10, the lever 14 rotates the disk 6 to a position in which the spring 5 completely releases the driven coupling half 4. If necessary, the drive 30 is retracted from the disk 11 and the device is switched on. This process is described above.

The proposed clutch provides the ability to transfer

5, the maximum torque, irrespective of the speed of the driven shaft, while the maximum load on the drive shaft is caused by the elastic element 28.

0 The most appropriate use of this clutch is in cases where the load on the driven shaft has a large moment of inertia and it takes a long time to accelerate it, as well as in cases where the load on the driven shaft may drastically increase to some time.

5 magnitude greater than the engine's normal power, and again fall to

NORMSHNOY.

This device can be used as an automatic progressive speed variator, the gear ratio of which depends on the load on the driven shaft and can smoothly change, ensuring the measurement of the number of revolutions of the driven shaft

5 from zero to the speed of the drive shaft.
