The invention relates to a device that prevents rolling down the incline of the vehicle stalled when the engine and faulty brakes.

Know the Parking brake device (AV.St. USSR N 1017549, CL; 06 T 3/00) containing two wedges connected by a spring bending. The ends of the springs are connected with the hinged wedges, and the middle part of the spring loop formed, which serves for gripping the upper part stornaiuolo wheel.

However, this device prevents rolling units not in extreme situations, and only when the unit is stopped and is steadily on the rise or slope, i.e. there is no threat of spontaneous rolling. In extreme situations, when the exercise movement on the rise this device can not apply, because the operator cannot leave the workplace (as well as the steering wheel and foot brakes) to install the device on the wheels of the vehicle.

The closest to p is P N 1291469, CL 60 T 1/14, 1987), which contains electrical sensor longitudinal roll of the vehicle, is included in the control circuit of the motor, kinematically associated with protivosemnye stops. In the control circuit also includes a generator connected to the shaft of the motor vehicle. When killing the engine of the vehicle is triggered and the electric sensor longitudinal roll generator generates a signal for lowering under the wheels of the transport stops.

The disadvantages include the following: the device may not work with pneumatic systems; in soft ground (for example, after the rain stops, udaliaias deep in the earth, under the pressure created by the weight of the vehicle is not able to provide protivostoit of the vehicle, which, as we know, can lead to an emergency situation.

The aim of the invention is to increase the effectiveness of braking, preventing the rolling of the vehicle downhill when stalled the engine and faulty brakes that use a pneumatic system.

This goal is achieved by the fact that the device has protivoopuholevymi mechanism in a longitudinal vertical plane, raznesennymi solenoid valves, installed in the pneumatic lines for supplying and discharging air in the gap between the piston and the wall side of each rod in the housing of the pneumatic cylinder is placed a spring, with the possibility of compression when moving rod, each ballast weights are rigidly connected by a lever with its brake protivojikotnam emphasis with the possibility of moving and embracing the upper part of the perimeter of the tire wheel of the vehicle, while the inner curved surface of the brake protivokrazhnogo stop is provided with a recess, the shape of the pattern mirror which corresponds to the convex tread tire wheel of the vehicle, moreover, the normally open electromagnetic valves, the left and right pneumatic cylinders connected with the normally closed contact of the second relay, the normally closed electromagnetic valves, the left and right pneumatic cylinders connected with normal razmoknut contact of the second relay, and the normally open contact of the first relay signal through a light bulb and a switch connected to the normally closed electromagnetic valve that is installed at the inlet of the pneumatic system before protivoopuholevymi mechanism in longitudinal vertical plosko the STI and brake protivochumnyj stops, moving and covering the upper part of the perimeter of the wheels of the vehicle through provided in these recesses, the shape of the pattern mirror which corresponds to the convex tread tire wheel of the vehicle, makes it possible to increase the braking effect, preventing the rolling of the vehicle downhill when stalled the engine and faulty brakes that use a pneumatic system.

The proposed solution is new, has significant differences, involves an inventive step, and industrial applicability, as well as unknown in our country and abroad.

The drawing shows a diagram protivokrazhnogo device of the vehicle.

The proposed device contains electrical sensor 1 longitudinal roll, equipped with a movable and stationary contacts 2 and 3, the gauge of frequency of rotation of the motor shaft of the vehicle, made in the form of the generator 4 DC, the first relay 5 with two pairs of normally open contacts 6 and 61and the second relay 7 normally open contact 8 and normally closed contact 9.

In the proposed device resimlerim element through the pneumatic valve 36.

The device operates as follows.

At a certain elevation profile sensor 1 longitudinal roll bends and when the key 11 supplies current to the relay 5. When current passes through it snapped two pairs of normally open contacts 6 and 61. With the closure of the contacts 61the current from the generator 4 through adjustable resistance 13 (with which regulate the time of breaking of the contacts 9) is supplied to the second relay 7, which thus opens the normally closed contacts 9 and at high speeds (large current in the generator 4) will close the contacts 8. Thus, when driving on a flat surface of the battery 10 is supplied to the power supply on the Central electrode of the electrical sensor roll 1, and pneumoconiosis 35 is supplied air under pressure in the pneumatic system and later in the pneumatic cylinders 15 and 16 (through the normally open electromagnetic valves 21 and 24), they manage ballast weights 19 and 20 are in their original state, aided by the condition of the springs 25, which is in the extended position when the release of ballast weights 19 and 20.

At lower speeds of the engine or when stalled motor current produced by generatorname) and through them when closed contacts 6 from the battery 10 is supplied current to the normally open electromagnetic valves 21 and 24, the left and right pneumatic cylinders, which will be triggered at the same time, the normally closed valve 31 is opened and the normally open electromagnetic valves 21 and 24 are closed. Through the open solenoid valve 31 and the air flows from the receiver 33 in pneumonia housing 14 of the pneumatic cylinders that work and throw out ballast weights 19 and 20, the left and right pneumatic cylinders.
