    A transmission shiftable to change transmission ratios by the operation of a member whose effectiveness depends upon a pressure fluid, e.g. through a valve communicating the fluid to actuators of the gear-change system, has a clutch connecting the output shaft of a prime mover as an internal-combustion engine with the input shaft of the transmission. According to the invention, the clutch-operating cylinder is connected by an entraining device with a valve controlling the pressure fluid. A lost motion may be provided between the operating member of the cylinder and the valve seats to ensure full opening of the clutch before operation of the transmission is enabled.

    This invention relates to a transport machinery industry. A blocking device for the transmission is known to contain a source of pressure for the working fluid and an actuating cylinder associated with the clutch pedal. In automobiles, in particular in construction-maintenance vehicles, such devices generally experience a heavy load. In order to prevent damage to the gear mechanism. The key, called by turning ON the gearbox when the clutch is engaged, has so far provided for devices on the connecting rod, which should prevent the gearbox from being turned on when the clutch is engaged. However, when driving with this device, the driver could turn on the gearbox without completely disengaging the clutch, which could result in damage. The purpose of the invention is to increase reliability in operation. This goal is achieved by the fact that the locking device for the gearbox, which contains the source of pressure of the working medium and the actuating cylinder connected to the clutch pedal, is equipped with a distributor for supplying the working medium to the gearbox, the input Kotoporo is connected to the source of pressure of the working medium and the outlets respectively transmissions and atmosphere, while the distributor is made in the form of a two-chamber cylinder, in one of the chambers of which a slider is installed, and in the other - a valve, in the partition between the chambers installed in parallel the cylinder axis, the bolt, one end of which is located in the slider, and the other has a ledge, the two-chamber cylinder being parallel to the axis of the executive cylinder, is fixed on the outer side of the latter and connected to it with a pin, and the inlet of the chamber with the valve is connected to the pressure source environment, and outputs - respectively with the gearbox and with the atmosphere. However, the valve is a cylindrical sleeve containing a shank and a valve plate, the end of which is connected to the inlet seat through a seal, the cylindrical sleeve being installed coaxially with the bolt and spring-loaded with two coaxially arranged springs relative to the cylinder body and the bulkhead, and the protrusion of the bolt is provided with an exhaust a seat located inside the intake seat. In this case, the slider is spring-loaded relative to the cylinder wall and provided with a hole for installation of an adtifta located perpendicular to the parallel longitudinal axes of the executive cylinder and the distributor, while the pin is placed with its other end into the groove formed on the outer part of the adjusting ring of the executive cylinder. FIG. Figure 1 shows the kinematic diagram of a distributor located on an actuating cylinder; in fig. 2.- the executive cylinder and the distributor fixed on it, a section. FIG. Figure 1 shows a locking device equipped with a valve that can be used in automobiles, working vehicles, etc. The device has a clutch 1, which can connect the drive shaft 2 to the shaft 3. The shaft 3 is connected to the gearbox 4, the output shaft 5 of which is connected to the driving wheels of the car or to another driving unit. Gearbox 4 can
    The unit is made arbitrarily in the form of transmission gears with several groups of gears that are controlled by a switching rod 6. The switching cable 6 can act only when the pipeline 7 (Fig. 1) is filled with a working medium, such as compressed air.
    The transmission includes a structural unit containing an actuating cylinder 8 and a distributor 9. A distributor 9 is connected via pipe 10 to a reservoir 11 with compressed air. The actuator cylinder includes a pipe 12, which is connected to a control cylinder 13 controlled by a clutch pedal 14. On the left side of the cylinder 8 is a piston rod 15, which acts on the end of the clutch lever, 20 turning around a pin 16 or so on. P. support element. The clutch lever 17 acts in a known manner through the throat on the clutch 1 in such a way that when the clutch lever is turned counter-clockwise, the clutch 1 is activated.
    On the continuation of the piston rod 15 on the inside of the three cylinders, there is a cylinder, a Q piston 18. The piston at the right end has a stuffing box 19 in order to prevent the leakage of hydraulic fluid. At the left end of the piston 18 is installed adjusting ring, operating with a frictional closure. The adjusting ring is provided along its outer perimeter with a groove 20, which includes a pin 21, acting as a leash. At the right end of the piston 40 there may be a spring 22 which, under the action of the clutch pedal 14, supports the action of the hydraulic fluid for displacing the piston 18. Located on the cylinder 8 45, the distributor 9 has a chamber on its left end. 23, in which the slider 24 which is engaged with the pin 21 is movably located. The slider 24 is screwed onto the end 50 of the bolt 25 can be locked in a certain position on the bolt 25 by a stopper element (not shown).
    At the opposite end, a bolt 25 with a protrusion 26 is held .in 55 a part of the distributor housing. The distributor contains the first outlet 27 of the distributor, which is connected to the pipeline 7, and the inlet 28 of the distributor, which is connected to the pipe 60 by the wire 10. The second outlet of the distributor 29, on which a splash guard or the like can be provided, is connected to the atmosphere. Bolt 25 passes between O-rings 30 and 5
    31 through the chamber 32 and has an outlet saddle 33 at the junction. This exhaust saddle can move the valve plate 34, which is provided with a sleeve nozzle concentrically surrounding the bolt 25, and is under the influence of two springs 35 and 36 parallel to it. Spring 35 rests on the steps of the expansion of the chamber 32, while the inner spring 36 rests on the outer left end of the chamber 32 (Fig. 2). At the right end of the valve plate 34 there is a rubber seal 37, which fits (Fig. 2) to the inlet seat 38. In this position, the working medium connection from the first outlet 27 of the distributor to the inlet 28 of the distributor is closed, while the connection of the first outlet 27, the distributor remains free with a second outlet 29 connected to the atmosphere.
    On the left (FIG. 2) end of the bolt 25, the spring 39 rests on the slider 24 and on the opposite inner wall of the distributor case in such a way that the compressive force of the spring 39 acts against the compressive force of the springs 35 and 36. The compressive force of the spring 39 can reach approximately 3 kg, with cymarna compressive force of springs 35 and 36 of about 7 kgf. Thus, both springs 35 and 36 provide a zero position, i.e. in which air is removed from the first, outlet 27, and there is no communication between the distributor inlet 28 and the second outlet 29.
    Principle of operation of the distributor.
    In the so-called zero position, air is removed from the first outlet 27 of the distributor, since the pipeline 7 is not under pressure, therefore, the transmission 4 is not activated when the switching valve 6, 6 or other mechanical effects are triggered. In this position, the distributor is triggered. the clutch 1 and the transfer of force between the shaft 2 and the output shaft 5.
    If the clutch pedal is now activated, the executive cylinder .8 is loaded through conduit 12, and piston 18 (Fig. 2) performs a left-directed movement. The piston rod 15 rotates the clutch lever 17 and the clutch is disengaged after a certain partial travel of the clutch. During this left-directed movement, the pin; 21 acts as a traction organ in such a way that the slider 24 is directed to the left inside the chamber 23. This movement is supported by the action of the spring 39. After a certain incomplete travel corresponding to the uncoupling path, the outlet 33 is attached to the rubber seal 37 located on the valve plate 34, i.e. the exhaust seat is closed. At the same time, the inlet seat 38 is opened, since the outlet seat located on the protrusion 26 retracts the valve plate 34 against the compression force of the springs 35 and 36 from the intake seat. Therefore, the movement of the bolt occurs against the direction of the general compressive force of the springs 35. and 36, while the spring 39, acting against the springs 35 and 36, reduces the control force. This reduction gives a special advantage, since the force required by the pin 21 to control the executive cylinder 8 is not large enough due to the use of an adjusting ring 40 acting as a slip clutch. Due to the closure of the exhaust seat 33, the connection from the first distributor outlet 27 to the second distributor outlet 29 is interrupted, while the opening of the intake saddle 38 forms a connection between the first distributor outlet 27 and the distributor input 28. Through the compressed air reservoir 11 connected to the compressed air reservoir 11, the distributor enters compressed air at the dispenser outlet 27, and through the pipe 7 the compressed air enters the gearbox 4 so that it can be activated. Therefore, this engagement occurs with the clutch disengaged. If the exhaust seat 33 retracts the rubber seal 37 away from the intake during its left-facing movement (Fig. 2): o the seat 38, the pressure through the distributor inlet 28 intermittently affects the large surface of the rubber seal 37, since the outlet seat 33 has a smaller diameter, than the intake seat 38. However, both springs 35 and 36 prevent valve plate 34, respectively, valve 41 from moving too much to the left following this abrupt action of force, thus ensuring that panna plate 34 moves not to stop and remains in ztom position. If gearbox 4 is engaged, you can again release from the distributor, the clutch pedal 14 is released and as a result, the pressure on the piston 18 is terminated, then you can re-engage the clutch 1 using (not shown j spring devices or the like) Due to this, the clutch lever 17 turns against the direction of the clockwise rotation so that the piston 18 (Fig. 2) is displaced to the right until the adjusting ring rests on the shoulder. Movement through the pin 21 ne It is installed on the bolt 25 in such a way that before engaging the clutch 1 the inlet seat 38 closes and the exhaust seat 33 opens to release the compressed air from the outlet 27 of the distributor and the pipeline 7. When the clutch is engaged, the gearbox cannot be turned on anymore because of the absence of compressed air piping 7. This prevents damage to the gearbox due to shifting when the clutch is engaged. The hub-shaped adjusting ring 40 acts automatically as a slip clutch, t. e. The piston rod 15 always adjoins the gap to the clutch lever 17, whereby the wear of the coupling is also leveled. The stroke of the piston 18 and thereby the stroke of the distributor are determined by the fit of the adjusting ring 40 to the spring retaining ring 42 (Fig. 2.). The device is not limited to a special design of the actuating cylinder 8, i.e. instead of the adjusting ring 40, other adjusting devices can also be used that contain a stopper acting with a positive locking. Thus, the proposed device significantly increases the reliability in operation. ,
