During normal driving these members lock braking unit having pressing power cylinder. Lower part of braking unit is shaped as rake which fingers engage road pavement. Brake is located under rear trunk. EFFECT: fast and reliable braking and car alignment during skidding. 2 cl, 3 dwg

Description

 The invention relates to mechanical engineering, in particular to brake devices of cars.

 Known types of brake shoe, disk, wedge type, located directly in the drums of the driving and driven wheels of the chassis of the car, as well as in the form of aprons thrown under the tires of the driving wheels.

 Their disadvantage is the direct effect on stopping the rotation of the wheels on pneumatic tires. Structural complexity, inoperability (breakdown, loss of friction of antifriction material in the event of water getting between rubbing parts and so on). All of these existing braking mechanisms do not ensure the reliability and urgency of stopping the transport in front of an obstacle or when the car skids on slippery sections of roads. The acceleration force is not extinguished urgently, therefore, the braking distance on a dry road depending on the speed of the latter increases proportionally. For example, at a speed of 30 km / h, the braking distance of a car on a dry road is 7.2 m, etc.

 The main disadvantage of existing brakes is the inability to level the car from skidding.

 The purpose of the invention is the introduction of an additional braking device "Anchor" with the exclusive use of "it" only in emergency cases (hitting an obstacle, skidding or sliding the car in a dangerous direction, self-propelling, inaudible steering, tipping over, etc.).

 In FIG. 1 shows the installation of a brake device (on the bottom of the trunk); in FIG. 2 brake device (as an appendage to the car); figure 3 device anchor brakes.

 The frame 2 is attached to the bottom of the trunk of car 1 (see figure 1) with special bolts along the central axial longitudinal line (as a towing device for semi-trailers). The lug-anchor 3 (see figure 2) is in the transport position and is held by the latch 8, which is brought into the "opening" by the cable 9 (see figure 1) through the rollers 10 to the lever 11.

 In FIG. 2 shows an anchor-brake device 2, which includes a rake anchor 3, a beam arm 4, an axis-holder 5, an emphasis-column 6, its axis-holder 7, a latch-lock 8.

 The anchor rake 3 consists of three teeth 12, the springs 13 installed in the cups 14, to fix the rake-anchor in the transport, it is placed in the groove of the body 15 (see figure 2), which is bolted to the bottom of the trunk of a car of any make.

 Figure 3 shows the device of the rake-anchor and the scheme of "laying" the device in transport. An anchor rake 3 is attached to a rod, which is spring-loaded with a coil spring 17. The rod is placed in cylinder 18. The “Hand” cylinder is hinged to the elbow extension, which, through its rod 20, is pivotally attached to the “YaTU” body 15. For reliable closure in the transport position of the "elbow" has a second latch 21 with a common drive from the "emergency" lever 11 (see figure 1). Column 6 (see Fig. 3) has a spring 22, which supports a certain pressure on the rake anchor through the elbow cylinder 19.

 The work of the rake anchor is as follows.

 When skidding with the right or left side of the body (across the road), it is urgent to pull the lever 11. The hooks 8 and 21 will come out of the grooves of the "anchor" and the protrusion of the "elbow".

Under the influence of gravity, the rake-anchor 3 and the cylinder of the beam of the hand fall on the road plane and the "elbow", elongating along its main axis, makes it possible for the rake-anchor to fall with its teeth perpendicular to the plane of the road, and the tooth springs 3 to take the transverse profile of the roadway plane. By virtue of the inertia forces “a”, the rake-anchor 3, having fixed itself in the ice of the road, receives the reaction force R 2 and, overcoming the resistance of the spring 17, goes into the position of the reaction force R 1, while braking the force F m · a to a certain speed V _x her to V 0.
