At the opposite ends of the roller 5, two levers 12 and 13 are fixed.

Lever 13 with cylindrical

heads 14 are selectively coupled with drivers 8 and 9 of shafts 6 and 7 and can insert two pairs of 2s tangles 2i .. and reverse drive gear Z3.X with forks 10 and 11 into engagement with the driven shaft 15 of the transmission 15 (Fig. 1-3 and 13 ). In an embodiment, the fork 11 may include reverse gear and an additional fifth gear (not shown). The lever 12 is pivotally connected by the head 16 of the lever 4 with the input control shaft 2 (Fig. 1 and 2).

An additional axle 17 is fixed in the crankcase 1 with an additional fork 18 and a leash 19 mounted on it, which are axially stirred and spring-loaded relative to the crankcase 1 by the spring 20. The additional fork 18 is in cooperation with the corresponding coupling pair of gears || - and is fixed on the additional axis 17 pin 21 (Fig. 1 -

In the embodiment (Fig. 11), the fixing of the additional fork 18 is carried out by the ball 22, the spring 23 and using the corresponding bald faces and holes made on the additional axis 17.

The spring 20 provides for the creation of an additional force that prevents the return of the additional plug 18 to the extreme position, and an alarm signaling the start of electing the programs.

On the control input shaft 2, an additional lever 24 with a spherical head 25 is mounted with a slider 3 and adapted to interact with the groove of the additional leash 19. The spherical head 25 has a spherical end 26 of radius R with the center of the sphere located on the axis of the control input shaft 2 (FIG. 5 and 6) and is additionally provided with a radially directed rod 27, whose axis is aligned with the axis passing through the center of the spherical end 26. The rod 27 is located in the threaded hole of the additional lever 24 of the input shaft 2 Regents axially movable and fixing these positions by means of nut 28 (FIGS. 5 and 6).

The axis of the cylindrical section 29 in the extreme position of the additional leash 19 combined with the axis of the input shaft 2 control (Fig. 7).

Such profiles of the additional driver 19 and the lever 24 allow, at one position of the additional driver 19, to carry out an additional rotation and axial movement of the input control shaft 2 and to prevent any movement of the additional driver 19 without additional actions of the additional lever 24.

In the crankcase 1 against the middle part of the trapezoidal slot 32 is fixed a conical element made in the form of a conical end 33 on the screw 34. The diametrical cross section of the conical end 33 is made congruent to the section of the trapezoidal slot 32 of the radial protrusion 31 of the slide 3. The conical end 33 is configured to selectively interact with the lateral surfaces of the radial protrusion 31 and its trapezoidal slot 32. The roller 5 with its face surface

FIG. 9 and 10 show an embodiment of an additional leash 41 mounted on an axis 42, which contains an additional cylindrical portion 43, made with a radius equal to the radius of the spherical end 26 of the spherical head 24, symmetrically to the first cylindrical portion 29 and bounded by the other side of the groove of the additional leash 41 and the end of the second protrusion 30. Moreover, the axis of the second cylindrical section 43 in the other extreme position of the additional leash 41 is aligned with the axis of the input control shaft 2. This embodiment of the additional leash 41 allows

Q control transmission containing additional gears.

In an embodiment, with a sufficiently large radius of the spherical end 26 of the spherical head 25 of the additional lever 24, the cylindrical section 29 of the additional leash 19 is designed as an inclined plane 44 (Fig. 11).

Thus, in the neutral position, the angular displacement of the input control shaft 2 is limited on one side

force of the spring 20 acting on the additional plug 18, and on the other hand the force of the spring 37 of the alarm device 35 interacting with the roller 5. In the axial direction, the movement of the control input shaft 2 is limited by the interaction of the surfaces of the trapezoidal slot 32 of the radial protrusion 31 of the slide 3 with the conical end 33 of the screw 34

The device works as follows.

An external force, such as a driver, is applied to the input control shaft 2 to engage the gears, turning it from the neutral to the left position (FIG. 3). Together with the control input shaft 2, the slider 3 is rotated with the lever 4, the additional lever 24 and the radial protrusion 31.

The additional lever 24 with its spherical head 25, acting on the additional leash 19 and compressing the spring 20, displaces the additional plug 18 to the extreme left position, which with the help of the coupling connects a pair of gears to the driven shaft 15, which is connected to the first differential gear. and second gear reducer.

In this case, the lever 4, acting on the lever 12 of the roller 5, moves it with the lever 13 in the axial direction to the extreme upper position. The cylindrical head 14 of the lever 13 occupies the uppermost position in the groove of the driver 8 of the rod 6.

The radial protrusion 31 of the slider 3 is displaced relative to the conical end 33 of the screw 34 to the right position, making it possible to move the control input shaft 2 in the axial direction.

Then, by moving forward, the input control shaft 2 is moved in the axial direction. Moreover, the additional lever 24 slides along the groove of the additional leash 19 with its spherical head 25, without affecting the additional plug 18, and the lever 4, acting on the lever 12, turns the roller 5 clockwise, moving the lever 13 in the same direction at the same time. I act cylindrical head 14 on the lead 8, moves the brush 6 together with the fork 10 in the axial direction. Fork 10, acting on the clutch, connects with the driven shaft 15 a pair of two-stage gearboxes.

When moving, the shaft 6 slides against the shaft 7, displacing with its hole relative to the locking element 39, locking it in the hole of the shaft 6, thereby preventing its arbitrary movement. In the extreme position, the scraper 6 is fixed by a ball 40, interacting with the well of the scraper 6. When the slider 3 is moved, the radial protrusion 31 slides freely along the conical end 33 of the screw-34. There is a simultaneous inclusion of a set of gear - corresponding to the first gear, and locking elements.

To engage the second gear, the input control shaft 2 is moved in the axial direction to the rear. In this case, the spherical head 25 of the additional lever 24 slides along the groove of the additional leash 19 without affecting the additional fork 18, and the lever 4, acting on the lever 12, turns the roller 5 with the lever 13 in the opposite direction. The lever 13, the action of the cylindrical head 14 on the lead 8, moves the brush 6 together with the fork 10 in the axial reverse direction to the extreme right position.

The plug 10 acts on the clutch engagement, disconnects a pair of gears from the output shaft 15 and includes a second pair of gears - a gearbox. When the slider 3 is moved, the radial protrusion 31 slides freely along the conical end 33 of the screw 34, and the brush 7 is locked with a locking element 39. The set of gears - corresponding to the second gear is activated.

To select the third gear, the input control shaft 2 through the neutral position is rotated in the opposite direction, in particular, to the right.

The auxiliary lever 24, which rotates together with the input shaft 2 of the control, acts on the auxiliary leash 19, displaces the auxiliary plug 18 to the extreme right position. Lastly, I act on the clutch, first disconnects the pair of gears, and then connects with the driven shaft 15 a second pair of gears, connected to the differential case, which is not working in the third and fourth gears of the gearbox.

At the same time, turning together with the input control shaft 2, the lever 4, through the lever 12 on the roller 5, moves it with the lever 13 in the axial direction to the middle position. The cylindrical head 14 of the lever 13 occupies an extreme position in the groove of the leash 8 of the rod 6.

The radial protrusion 31 of the slider 3 is displaced relative to the conical end 33 of the screw 34 to the left position, freeing it from interacting with the surface of the trapezoidal slot 32 and providing the ability to move the input control shaft 2 in the axial direction.

Then, the input control shaft 2 is moved axially forward. The additional lever 24, moving, slides along the groove of the additional leash 19, does not affect the additional plug 18, and the lever 4, acting on the lever 12, rotates the roller 5 together with the lever 13. The cylindrical head 14 of the lever 13, acts on the leash 6, moves the rod 6 with the fork 10 in the axial direction to the extreme left position. The fork 10 connects with the driven shaft 15 of the transmission a pair of gears - a gearbox. In this case, the rods 7 and 6 are fixed in a known manner, and the radial protrusion 3 of the slide 3 with its lateral surface freely slides along the conical end 33 of the screw 34. Simultaneous engagement of the set of gears fi-, corresponding to third gear, occurs.

To enable the fourth gear, the control input shaft 2 is moved in the axial direction to the rear. In this case, the spherical head 25 of the additional lever 24 slides along the groove of the additional leash 19, without affecting the additional fork 18, and the lever 4, acting on the lever 12, rotates the roller 5 with the lever 13 in the opposite direction (counterclockwise).

The cylindrical head 14, acting on the leash 8, moves the rod 6 and the fork 10 in the opposite direction to the extreme right position. The plug 10, acting on the clutch, disengages the pair of gears and engages with the driven shaft 15 a second pair of gears 5 of the gearbox. The rod 6 is fixed in a known manner, and the radial protrusion 31 of the slider 3 slides freely along the conical end 33 of the screw 34. The set of gears - -, corresponding to the fourth gear, is activated.

To engage the reverse drive with an external force, the control input shaft 2 is rotated to the extreme right position (Fig. 3). The additional fork 18 remains in the extreme right position, which corresponds to the inclusion of a pair of bristles associated with the differential. When moving the control input shaft 2, an additional lever 24 with a spherical end 26 of the spherical head 25 slides along the cylindrical surface of the section 29 of the additional lead 19 up to the stop against the protrusion 30.

In this position, the additional fork 18 is locked on one side by the fork on the crankcase 1 and on the other side by the spherical end 26 of the spherical head 25 of the additional lever 24.

The lever 4 of the slider 3, through the lever 12 on the roller 5, moves it with the lever 13 in the axial direction to the lower position. In this case, the roller 5, acting on the cup 38, compresses the spring 37, which signals the beginning of the reverse gear.

The cylindrical head 14 occupies the lowest position and is located in the slot of the driver 9 of the stem 7. In this angular position of the input control shaft 2, it is moved axially backward. At the same time, the Additional lever 24 with the spherical end 26 of the spherical head 25 slides along the cylindrical section 29 of the additional leash 19, without affecting the additional fork 18, which remains locked. The lever 4 of the slide 3, acting on the lever 12, turns the roller 5 with the lever 13 counterclockwise.

The lever 13, the action of the cylindrical head 14 on the leash 9, moves the rod

7, along with the fork 11 in the axial direction to the extreme right position. The fork 11, which is connected to the intermediate rezhesche zheshche Zjx, engages it in engagement with the drive shaft shafts, which corresponds to the engagement of the reverse. The rods 6 and 7 are fixed in a known manner by a locking element 39 and a ball 40, which interact with the corresponding holes in the rods.

0 In the neutral position, the leverage system is transferred by acting on the input shaft 2 of the control sequentially in the opposite direction.

If there are additional gears, for example, the fifth gear, its activation is made by the rod 7 when the control input shaft 2 is moved in the opposite direction.

In the embodiment of the additional leash 41 with two cylindrical surfaces 29 and 43 (Fig. 9 and 10), the inclusion

0 additional gears are made when the input control shaft 2 is transferred through the neutral in the opposite direction.

The additional fork 18 remains in the leftmost position, which corresponds to the inclusion of a pair of bristles associated with the differential, and the spherical end 26 of the additional lever 24 of the spherical head 25 slides along the cylindrical surface of the driver section 43 up to the stop.

8 this position, moving the input control shaft 2 in the axial direction, through

a system of levers using a rod and forks include additional gears (not shown).

Thus, the transmission switching circuit (FIG. 4) corresponds to the generally accepted transmission switching circuit of a vehicle, in particular a car. Therefore, the use of the proposed design of the transmission transmission engagement mechanism does not create an inconvenience in its use.
