Abstract

FIELD: transport engineering. The purpose of the invention is to increase the comfort of control and reduce the time of disinhibition. The pusher 6 of the spring energy storage device has a release mechanism and an unlocking spring 21, which is compressed when the compressed air is supplied to the energy storage device. The trigger mechanism fixes a spring 21 with the aid of a rusk element in the form of a ball 14. The spurious 4 has a traction electromagnet consisting of a solenoid 16 and a yoke 17. A voltage is applied to the solenoid 16 of the electromagnet to release the vehicle wheels. The anchor 18 of the electromagnet acts on the ball 14 of the trigger mechanism, which releases the spring 21. The spring 21, overcoming the force of the spring-loaded clamp 9, moves it until the balls 8 of the lock mechanism connecting the piston 4 to the push rod 6 is retracted. 1 Il. 16 p / g y - / 3 8426 J / / I (L oo O5 00 OO d th

Description

one

The invention relates to trais1; assorted means and concerns a brake chamber with a spring-loaded energy storage device, which is not intended for activating the brakes of the rear wheels of a truck or standing in its parking lot or in the event of a defective working braking system.

The purpose of the invention is to improve the convenience of H1N1I and reduce the time of resorption.

The drawing shows a brake chamber with a spring energy storage device, a longitudinal section.

The spring-loaded energy accumulator, mounted behind the working brake chamber 1, includes a housing 2 with a lid 3, in which nopinenb 4 is located. A spring 5 is loaded into the hatch, 5 is loaded, and the piston is 4. The last reach1) i5 is a hollow plunger 6, e; iy- to transfer force from the 4 to the brake. On the side of the brake chamber 1, the pusher 6 is closed by a plug-in pressed into 7. For connecting 4 to 4 with the pusher 6, there is a locking mechanism, consisting of dry elements in the form of jigs 8, for which there is no collar in the pore. Rusk elements are located in the apertures of the wall of the pusher 6. To insert the rusks into the groove of the piston 4 and hold them in this groove, there is a clamp 9, but the circumference of which is made up of a ring groove of irregular, smoothly varying depth. In the retainer 9, a locking spring 10 is unwound, from the other end of which there is a descent mechanism fixed from a non-) Egsena by a retaining ring 11.

The mechanism of removal consists of a sleeve 12, a latch 13, made in the form of an axis with a ko, lg, Eva floating -: with the spectacle and a cyxapnoi o element of the ball 14. For an equal distribution of effort and: the creation of Hanpai- CHie two axes (without annular grooves), which are from K to 1 (PP1, and reinforced with plastic plastic ynhei 15. On the right side of the lid, the crimping electromagnet, the state of solenoid 16 and yoke 17, is attached. directions for norshn and prevents the balls from falling out 8 at rasmatzhivan. At the end of the pusher 6 with the electro-magnetTopoiibi have two grooves in which you insert electromagnet measles 18. The crust from the grooves is drawn in by the stator ring 19. Between the blind plug 7 and the stem 20 with the shoulder, the unlocking spring 21. The bar 20 has an annular groove with .: By iodine ohm.

D. 1I apply a spring-loaded brake chamber to a working readiness in a nolost 22 which is supplied with compressed air under pressure, which moves HopHjeiib 4 towards the edge 3, compressing the spring 5. In this case, 1grn, 1en 4, underestimated

and the position shown in the drawing, and the rod 20 reaches the stop in the cover 3.: - i lowers (cocks) the spring 21.

In this case, the annular groove on the rod 20 is aligned with the hole in the sleeve 12, in which there is a rusk element 14, which occupies by means of the spring 10 and the clamp 13 a position in the annular groove on the rod 20. Then the guide 15 with the clamp 13 takes the leftmost position and fixes in In this position, the rod 20 and the spring 21. For stopping the car on the stand, the compressed air from the bottom 22 is released into the atmosphere, and then the piston 4 under the action of the spring 5 moves towards the brake chamber, carrying it through the locks a pusher mechanism 6 which acts on nggok brake chamber associated with a brake.

To release the brake mechanism in the absence of compressed air in the brake actuator (for example, to tow a car) or to immediately move the vehicle, a voltage must be applied to the traction electromagnet. At the same time, the measles 18 is attracted to the holder 17 while simultaneously pressing the sleeve 15. The latch 13 is displaced to the right until the annular groove overlaps with the hole, where you find the balloon 14, which is recessed into the annular groove on the clamp 13 and releases the rod 20. Under the action of the spring 21, the clamp 9 is displaced towards the cover 3 and the rusk elements are embedded in the annular groove of the latch 9. The normal energy storage of the pusher is disconnected, i.e., the release.

In case of malfunctioning of the electrical equipment (lack of voltage) manual release is provided. To do this, it is necessary through the hole in the sanune 23 to press the manipulating 15.
