And: obrsgon11s relate to the K1111I11stroevem1O trapsporma, and, in particular, to the control mechanisms of speed gearboxes with centralized friction clutches TiiaKTOpoiJ and similar man1H11.

A mechanism is known for controlling the transmission gear box and the transmission line containing the distalolator, which is connected to the pressure source 1 |.

However, this mechanism does not discredit the adjustment of the friction clutch inclusion function depending on the unacceptable acceleration of the transport means, which does not ensure the normalized movement of the movement when switching gears and worsens the driver's working conditions.

A mechanism is also known for controlling a transmission box of a transport device, which is connected to the rail line 11) with a distributor, a source of electricity, connected to the output channels with a mass of 1 m vanity, an inertial valve with an unbalanced mass and a controlled flow, mounted on the frame of the vehicle parallel to its horizontal axis | 2.

A disadvantage of the known mechanism is the complexity of the design due to the complexity of the design of the inertial clanan. This is due to the presence of inertial mass, two flow controllers, two input and two output channels, drainage channels, as well as a number of canan seals. In addition, the installation of the well-known valve on the vehicle frame is very difficult due to the eight-way outlets.

The purpose of the invention is to improve the structure.

The mechanism contains a pump I, opf.-2, line 3 of the control, distribute.-c, 4 controls of the power ciliidrap 5 (|| section couplings 6. The rear axle; 1m, the clan 7 is equipped with an interstate valve 8, the inlet 9 of which It is connected with the main line 3, and the output 10 - with the oil bath 11. The inertial clan 8 consists of a body 12, in which is placed a cylindrical body (zolototnik) 13, spring-loaded from the ends 14 and 15 by springs 16 and 17. On the cylindrical top surface of the spool 13 made two conceptual grooves 18 and 19, and in the body - two diam etural bores 20 and 21 and axial bore 22 communicating

0 between it, while the input channel 9 is brought to the new 23, located between the grooves 18 and 19, and the output 10 is made near the end 15.

Gearbox control

Traction means works as follows.

When switching gears, the vehicle begins to move rapidly or

0 is slow, while the inertia force acts on the spool 13, proportional in magnitude and inverse to the direction of acceleration or deceleration. Under the action of this force, the valve 13, compressing one of the springs 16 or 17, displaces and connects one of the grooves 18 or 19 to the inlet channel 9, or a part of the liquid to drain. The pressure in line 3 of the control and in the power cylinder 5 of the clutch 6 being engaged is reduced, reducing the moment not disturbed by this clutch, which will decrease the acceleration or deceleration rate of the vehicle. When the acceleration or deceleration intensity decreases to a regulated value regulated by the gaskets 24, the spool 13 returns to the neutral position due to the force of the springs 16 and 17, disconnecting the control line 3 to the oil vanpa 11.

Thus, the implementation of the inertia mass and flow controllers in the form of a single cylindrical body spring-loaded from the ends, provided with two concentric caiacs, two diameters. holes located in the grooves, and axial holes facing the ends. 5, wherein the input channel is connected with sc. located between the grooves, and the output - with one of the ends, eliminates the need for separate inertia masses
