    专利说明:

    it is connected to the brake valve 3 and has an inclined annular surface 4 that acts on three. contacts 5.6 and 7 of the elements 8.9 and 1 of the switching of the electric step switch 11 of a three hundred foam retarder. In figs 1, 2 and 5, the device is shown in the resting position, i.e. One of the three stages G, G1 and ill of the switching of the electric step switch 11 is not switched on. Elem. 2NTY 8.9 and 10 of the switch are adjustable in height, which allows you to install different levels 1, P - 1P. switch depending on the operating conditions or braking the car. - Under the pedal 1 mounted on the axis 12 so as to rotate relative to the base plate 13, the sleeves 14 and 15 are set to rotate on the frame 16 consisting of two crossbars 17 and 18 and two side walls 19 and 20. The rotation is limited to mounted on the supporting plate 13 is adjustable by its height stop 21. Between the side walls 19 and 20 there is a torsion spring 22 centered by sleeves 14 and 15, which; with its long shoulder 23, it attaches to the crossbar 18, and with its short end section 24 to the screws 25, and is prestressed with the frame 16. The preload of this torsion spring 22 can be adjusted with washers 26, cursed between the crossbar 18 and On the frame 16 there is a stop 27, adjustable by a screw 28. In Fig. 7, the solid line shows the change in brake pressure, and the PUNTING button shows the change in force N by Pedal depending on the angles of the pedal gate, which are on the horizontal axis, where - the start point of step 1 is slow tel, b -. change the force on the pedal, c is the switching point of step P, and the switch on point of step Hi. When the pedal 1 is pressed down, the rod 2 moves down as well and the contact 5 of the switching element 8 moves under the action of a spring (not shown) on the surface 4, in the result of which the retarder switching stage 1 is activated. Further pressing down, the pedal 1 rests on the stop 27 on the frame 16, as a result of which the pedal 1 is carried away by the frame 16 against the action of the spring 22 upon reaching the tangible change in force on the pedal 1, only after reaching this point does the change occur Switching 9 includes a retarder switching stage 11. Then, with further downward movement, the actual operation of the brake valve of the automobile begins, i.e. air is supplied to the friction brake or service brake system, and only then in FIG. 7 the switching element 10 switches on the stage Z of the retarder switching. In FIG. 8, the technical solution applied when a second point of noticeable change in force is desired between the step P and the switch step w. In this case, an additional device 29 is attached to the upper crossbar 18 of the frame 16, the thickness of the fastening element 30 of which allows determining the size of the preliminary tension of the spring 22. In the housing 31 of the device 29, a compression spring 32 is installed, on the upper end of which pressure member 33 is located. Preloading the spring 32 and adjust the position of the pressure member 33 screw 34. The device for creating two points of perceptible pressure change of this variant works as follows. When the pedal 1 is pressed down, even before it comes into contact with the pressure element 33, the switching stage 1 is switched on. At the moment of overcoming the load, the spring 32 senses the first point of change of force on the pedgsha. By further pressing down the pedal 1 and that caNftJM and Hc1jimnyh element 33 against the action of the spring 32 is turned on - stage II switching. It is important that the spring preload 22 exceeds the spring preload 32 so that the frame 16 participates in pedaling the pedal 1 only when the pedal begins to act on the podoeo 18 that serves as the foot, and the force applied by the foot to the pedal overcomes the force of the loaded spring 22, with the result that at the same time the second point of force change on the pedals is felt. After overcoming the second point of force change and with further downward movement against the action of the spring 22, stage II of the moderator is activated, after the air is pre-supplied to the service brake system by normal operation of the brake valve. Fig. 9 shows another embodiment of the device. The device includes a housing 35 in which a compression spring 36 is installed under preload, and a ball 37 pressed down by a compression spring 36 to the rod 2. Stem 2 has two padias 38.39 and a guide groove 40,
    When the pedal 1 is pressed down, the ball 37, due to the simultaneous movement of the rod 2 down, is pressed first to the part of the wall of the notch with a radius of 38 under the action of the spring 36. In this zone of movement, the level G of deceleration is decelerated. The first point of change in sylLIA occurs when the ball 37 moves down through the intersection of the arcs with two different radii 38 and 39, with further movement of the rod 2, and then under the action of the spring 36 is pressed against the wall of the notch part, the second radius 39 , and the AND switch stage is turned on. The second force change point is felt before stage III is turned on, when ball 37 moves through the intersection point formed with radius 39 and guide groove 40.
    The position of the points of change of force can be adjusted by turning the housing 35, with the ball 37 moving up and down.
