control by means of a bolted joint 10. Inside the housing and the roof there are two diametrically opposed rectangular shaped protrusions 11 and two diametrically opposed guide rods 12 with travel stops 13 to ensure and restrict the longitudinal movement of the locking frame 14.

The steering wheel shut-off device has a sleeve 15 with a flange 16 of a rounded rectangular shape, for interacting with profile cams 17 and 18 and clamps 19 and 20, and two diametrically opposite longitudinal openings 21 for providing longitudinal movement of coupling 15 under the action of spring 22 relative to the studs 23 inserted into the holes 24 and 25 of the lower part 5 of the steering shaft. On the inner surface of the coupling 15 there are splines for engagement with splined tips 26 of the lower 5 and upper 4 parts of the steering shaft, between the ends of which there is a tape ball bearing 27 mounted on the projection 28 of the lower part of the steering shaft. Clamps 19 and 20 are rigidly connected to spring-loaded spring 29 by rocker arms 30 placed in the cylindrical cavity of the lower part 5 of the steering shaft, one ends of which are inserted into the hole 31 of the stud 23, while others with their projections 32 enter the holes 33 of the lower part 5 of the steering shaft management

The locking device has a rectangular shape that can be moved along the guide lugs 1 and the guide bars 12 spring-loaded 34 relative to the washer 35 pressed under the washer 35 and locking frame 14, which cooperates with the profile cams 36 and 37, in which two rectangular holes 38 and 39 for free running of the profile cams 17 and 18 in the process of activating the anti-theft device, two notches 40 for interacting with two rectangular shapes with locking lugs 41 and 42 of the lower part 5 of the steering shaft two cuttings 43 interacting with the protrusions 32 of the rocker arms 30, and a hole 44 for free rotation of the lower part 5 of the steering shaft.

To eliminate the longitudinal movement of the lower 5 and upper 4 parts of the steering shaft relative to the housing of the anti-theft device, they are provided with annular thrust projections 45 and 46 that interact with the thrust ball bearings 47. The lower part of the steering shaft has an internal spline tip 48 for connecting it to shaft worm steering gear.

The anti-theft device cocking and deactivating mechanism includes a gear sector 49, spring-loaded to the gear 51, which is rigidly seated on the slots of the charging axis 50, by means of a torsion spring 52, a coupling 53 with ratchet teeth, a coaxial axis 50 sliding along the birds, and spring-loaded spring-loaded relative to the gear 51 51 on the axle 50 of the cocking using a thrust ball bearing abutting a washer 55 pressed against the body, a disk stop 5 with ratchet teeth and a 57 take along the circumference to interact with the retainer 58, with it installed on two sharikopodship

Nick axes of the cocking axle 50, the pinion gears 59 and 60, which interact in one piece with the profile cams 18 and 37, the gear gear of the intermediate gear 62, transmitting the torque to the gear 63, made in one piece with the profile cam 17 and 36, finger 64, which is fixed one

the end of the torsion spring 65, the other end of which is fixed in the housing, which limits the angle 90 to the rotation of the cocking axis 50.

The latch 58, spring-loaded relative to the body 66 of the cylinder lock spring 67 to the pusher 6, placed in the cylinder mechanism 69 of the ignition lock and interacting with the key 7 ignition, interacts with the disk stop 56. Made in one piece with the toothed sector 49, the transition ring 70 has two diametrically opposite lug 71 for engagement with the ignition key 7. The torsion spring 52 creates a torque on the toothed sector 49 relative to the housing 6, the teeth 72 are made in the clutch of the cylinder mechanism, and the teeth 73 on the coupling stopper 56 are made. The mechanical stop 74 serves to limit the rotation of the gear sector 49 by an angle of more than 90 ° when an anti-theft device occurs

When the ignition key 7 is removed from the cylinder mechanism 69 at position 3 (one hundred), the pusher 68 under the action of the spring-loaded 67 spring detent 58 moves to the center of the cylinder mechanism 69 together with a latch 58, which, coming out of the hole 57, releases the disk stop 56, the last under the action of the torsion spring 65, which is twisted when the anti-theft device is cocked, together with the gear wheel 51, the coupling 53 and the cocking axle 50 is rotated counterclockwise at an angle of 90 ° up to the stop of the finger 64 into the housing 1 (Fig.6), turning the cocking axis 50 when by The power of the intermediate gear 62 rotates the gears 61 and 63 in opposite directions with the same angular velocity, since the gear ratio of both gearboxes is equal to two (Fig. 6). The gears 61 and 63 rotate together with the profile cams 18, 37 and 17, 36. The cams 36 and 37 release the locking frame 14, which under the action of the cocked spring 34 slides along the direction of the axle 11 and 12 towards the locking projections 41 of the lower shaft 5 steering control

In doing so, the driver of the vehicle, turning and swinging the steering wheel, achieves combining

neither the cuts 40 of the fixing frame 14 and the locking protrusions 41 until the steering shaft lower part 5 is fully secured relative to the body of the anti-theft device and, thus, relative to the vehicle body.

At the end of the complete fixation, the frame 14, with its two sections 43, runs onto the projections 32 of the rocker arms 30 and sinks them. At the same time, the latches 19 and 20 under the action of the rocker arms 30, compressing the spring 29 are sunk, releasing the clutch 15. Under the action of the spring 22, which is pressed while the anti-theft device is cocked, the clutch 15 moves towards the locking frame 34 along the spitz 26 and 5 upper 4 shaft parts steering control, descending from the psits of the upper part 4 of the steering shaft, thus disconnecting the upper part 4 of the steering shaft from the lower part 5. Thereafter, the steering wheel can freely rotate in all directions. The gear 51, turning, engages with the teeth of the toothed sector 49 pressed against it by the spring 52 and rotates it together with the transition ring 70 through an angle of 90 to the mechanical stop 74, i.e. to the initial position for raising the anti-theft device.

The disc stopper 56, turning 90, is installed by the following of its four holes 57 opposite the latch 58. When the anti-theft device is activated, the lower part 3 of the steering shaft is fixed relative to the vehicle body and the upper part 4 of the steering shaft is turned off, eliminating the possibility of mechanical action on the locking device on the steering wheel side.

To deactivate the anti-theft device and at the same time coax it, you need to insert the ignition key 7 into the ignition lock cylinder mechanism 6, turn the ignition key 7 clockwise from position 3 (stand) to position O (off), turning the steering wheel to combining the splines of the spline tips of the lower 5 and upper 4 parts of the steering shaft and the exit of the fixing frame

14 of engagement with locking protrusions 41.

The key 7 with its protrusion attaches to the pusher 68, which, shaking the spring 67, moves the latch 58 into the opening 57 of the disk stopper 56, locking it. At the same time, the lower part of the key 7 enters the opening of the adapter ring 70, while the protrusion 71 is located to the right of the key 7 (Fig. 14). When turning the ignition key 7 clockwise, its lower part, acting on the protrusion 71 of the transition ring, twisting the spring 52, rotates the toothed sector 49 by an angle of 90. The toothed sector 49, which is in engagement with the gear wheel 51, turns it and with it 50 cocks and coupling 53 with ratchet teeth. Due to the fixed position of the disk stopper 56 with four ratchet teeth 72 angled 90, the ratchet teeth of the coupling 53 with their bevels (4 pcs. Arranged at an angle of 90 ° with reverse than the ratchet teeth of the disk stopper 56, bevels) slides along bevel ratchet teeth of the disk stopper 56, pressing the spring 54.

The cocking axis 50, turning with its finger 64, twists the spring 65 and simultaneously rotates gear 63 with profile cams 17 and 36 (clockwise) and gear 61 with profile cams 18 and 27 (counterclockwise) through gearboxes 8 and 9. In this case (Fig. 6), the cams 17 and 18 first interact with the flange 16 of the coupling 15, pressing the spring 22, move the coupling 15 towards the upper part 4 of the steering shaft and when the splines of the splined tips of the upper 4 and lower 5 parts of the steering shaft coincide 15 engages with the upper part 4 of the steering shaft.

When the full displacement of the coupling 15 is reached, the longitudinal cams 36 and 37 interact with the fixing frame 14, pressing the spring 34, move the fixing frame 14 to the side of the spline {tip 48 of the lower part of the steering shaft 5). With this, the cams 17 and 18, while continuing to rotate, the clutch 15

no longer move, but only slide its profile around the surface of the flange 16, keeping the sleeve 15 in this position until the latches 19 and 20 are activated.

The locking frame 14, moving toward the spline tip 48, comes off the projections 32 of the rocker arms 30, under the action of the preloaded spring 29, the projections 32 emerge from the holes 33, and the latches 19 and 20 release the coupling 15 against reverse movement. Continuing to move on, the locking frame 14 (when the driver shakes the steering wheel) disengages from the locking lugs 41 and 42 of the lower part 5 of the steering shaft and releases it. When the cams 36 and 37 are rotated to the maximum value (the cams 17, 18, 36 to 37 are rotated by 180 °, as the axis of rotation is rotated by 30, and for gearboxes the gear ratio is two; fig. 10) the frame 14 takes the end position and held in it by cams 36 and 37.

When the coupling 53 rotates at an angle of 90, the working surfaces of its ratchet teeth and the disk stopper 56 engage under the action of the spring 54, fixing the cocking axis 50 in the cocked position, and with it the entire anti-theft device. In this case, the toothed sector 49 (sector 90) goes out of engagement with the fixed

gear 51 and pressed against it with its extreme tooth spring 52. Subsequently, when the ignition key 7 is turned in position 1 (ignition) and 2 (starter), the transition ring 70

together with the toothed sector 49 rotates clockwise, since the toothed sector 49 is not engaged with the gear 51, while the protrusion 71 of the adapter ring 70 is pressed against the bottom of the key 7 all the time by the spring 52.

When the key 7 is turned in position 1 and O, the adapter ring 70 with the toothed sector rotates behind the key. When the key 7 is moved from the position O to the position 3, the protrusion .71 and the adapter ring 70 together with the gear sector 49 with its extreme tooth, are pressed against the tooth of the fixed gear 51. At the same time, the lower part of the key 7 turns in the notch of the transition ring 70. If Since the key 7 at position 3 is not removed and is turned by the driver to the position O, the lower part of the key 7 is again turned in the notch of the transition ring 70, etc. When the key 7 is removed in position O, the anti-theft device does not work, since the pusher 68 becomes opposite to the latch 58 only when the key 7 is in position 3.

In order to prevent scoring on the surfaces of friction, the sharp edges of the splines of the cm, form pads 0.05-0.12 mm wide. The cams 17 and 18, in the process of raising the anti-theft device, transmit force to the flange of the coupling 15 throughout their rotation at two points diametrically opposite to the axis of symmetry of the coupling, which eliminates the transfer of the coupling during movement, and the cams 36 and 37 interact with the fixing frame 14 in the same way.
