Description

The free-wheeling mechanism is mounted on the driven link of the inertia clutch with the possibility of its rotation towards the driving link, and the cage is mounted in the housing. An automatic modeler has two modes of operation, the second of which is a quadruple, i.e. allows you to smoothly change, within certain limits, the angular velocity of the output shaft, depending on the load. It is compact due to the coaxial placement of all its elements, which simplifies the device and reduces weight. FIG. 1 Automatic transmission is depicted: in FIGS. 2 and 3, an inertial coupling in two projections, respectively.

The automatic transmission (Fig. 1) contains input 1 and output 2 shafts located on the same axial line, an inertial clutch 3, the drive link of which is mounted on the input shaft 1 of the coaxially driven link and the driven shaft 4 of this clutch, free-running mechanism 5 and differential. All transmission elements are aligned. Each of the three parts of the differential is connected respectively with the input 1 and output 2 of the transmission shaft and the driven shaft 4 of the inertial clutch 3. As a variant of the device shown in figure 1, the central wheels 6 and 7 differentials are installed respectively on the input shaft 1 and the driven shaft 4 of the inertial clutch, and drove 8 - on the output shaft 2; the Leading holder of the free-running mechanism 5 is mounted on the driven shaft 4 of the inertial coupling, allowing it to rotate in the direction of rotation in the single-shaft shaft 1, and the driven holder is installed in the housing 9 without letting the driven shaft 4 rotate in the direction opposite to the direction of rotation of the input shaft 1.-. /.:,: -: -.:; / ..; ..:. ...., .. /

In automatic transmission, any inertia clutches can be used; allowing the drive and the driven shaft to rotate at different frequencies and transmit the torque, the value of which is determined by the rotational speed of these shafts one Relative to the other, allowing the drive shaft to be installed coaxially to the driven shaft. In the inertial coupling (Figures 2 and 3), the driving member is made in the form of a ball 10 attached to the output shaft 1 of the rocker arm 10 with inertial loads 11 arranged in the form of bodies of rotation at its ends. The input shaft 1 is the coupling drive shaft. The slave link coupling is made in the form of an inclined disk 12 mounted on the driven hollow shaft 4 and in contact with the inertia

weights, B, central hole for free passage of the input shaft 1. hinge; the leading link 10 is made in the form of attached perpendicular to

an input shaft 1 of two spikes 13; serving axes of rotation of the frame 14, on which the rocker arm 10 is fixed. with the axial line of the input shaft 1. To this end, the frame 14 of the rocker arms is made with a bend, and the disk 12 - with a central notch. In order to eliminate the pulsating nature of the transmitted torque in the clutch on the additional rocker arms 15, installed with the possibility of rotation on the rods of the main rocker arm 10, can be

0 placed additional loads 16; axial line of rotation which passes through the axis of the coupling. ;

Automatic transmission works barely, duhly,. , /.,

5 The moment developed by the inertial clutch is determined by the change in the moment of the amount of movement of the inertial loads 11 as they move along the surface of the inclined disk 12 of the driven link.

0 Automatic transmission has two modes of operation.

The first mode of operation. With a large moment of resistance on the output shaft 2, a constant frequency of rotation of the input

5, shaft 1 and central wheel; b shaft 4, associated with the central wheel 7 of the differential, is fixed, since the free wheeling mechanism 5 prevents its rotation and the opposite side

0 compared to the input shaft 1. With a stationary driven shaft 4, the inertial clutch does not transmit or consume power, since it is not capable of converting mechamic energy into thermal energy.

5 The power from the engine over shaft 1 is transmitted to the central wheel 6 with the creation of the corresponding torque on it. With equal moments on the center wheels 6 and 7 of the differential on

0 drove B and output shaft 2 transmitted the sum of these moments. Consequently, a moment is transmitted to the output shaft 2, the magnitude of which is twice the moment on the input shaft 1, while

5, the frequency of rotation of the output shaft 2 will be two times less than the frequency of rotation of the input shaft 1, which is caused by the immobility of the central wheel 7. When the load on the output shaft 2 decreases, the load on its output 1749583 decreases accordingly.

the shaft of the inertial clutch 4 and it will begin to rotate under the action of the moment transmitted through the inertial clutch 3. Automatic transmission switches to the second mode of operation.

In the second mode of operation, the rotational speed of the driven shaft 4 of the inertia clutch and the associated central wheel 7 will depend on the load on the output shaft 2. Accordingly, the rotational speed of the output shaft 2 will be inversely related to the load applied to it, i.e. . the second mode of operation is variable.

With increasing load on the output shaft 2, the reverse process of transition from the second mode of operation to the first mode occurs.
