Technical field

The technical solution relates to the anti-skid device of a motor vehicle in the field of brake systems in the automotive industry.

Prior art

Previously known car braking systems operate on the principle of a brake system which includes brake components where the braking force is transmitted between fixed components mounted on the car axle and rotating components mounted on the car wheel and subsequently via wheel tires to the road. The effectiveness of the braking depends on the friction force between the tires and the road.

The disadvantage of this system in poor weather conditions, when the road is slippery, is that the friction force between the tires and the road is very low, and thus situations arise where the braking force is insufficient to safely brake and stabilize the car when braking.

The essence of the technical solution

These shortcomings are largely eliminated by the anti-skid device of the motor vehicle according to this technical solution, the essence of which consists in the fact that it consists of an interconnected mechanical system, a pneumatic system and an electronic system. The mechanical system consists of at least one brake flap with a friction surface. This flap is fixed at one end to the vehicle chassis by means of a pivot pin and at the other end to the vehicle chassis by means of an air piston. The pneumatic system consists of a pressure tank connected by air distribution to a load regulator, which is connected by air distribution with at least one electric air valve. Each electric air valve is connected by an air distribution to the air piston of a mechanical system. The electronic system consists of a control unit connected to each electric air valve of the pneumatic system via electrical wiring.

The advantage of this solution is that in case of worsened weather conditions, when the road is slippery, it can create a friction force between the vehicle and the road, which is independent of the friction force of the standard brake system and greater than the friction force between the tires and the road. to stabilize and decelerate the vehicle in the event of a skid.

The anti-skid device of a motor vehicle with one flap 51 is shown in Figures 1 and 3 and consists of an interconnected mechanical system 5, a pneumatic system 6 and an electronic system 7. The mechanical system 5 consists of a flap 51, a pin 52 and an air piston 53 which are fixed to the chassis 2 of the vehicle 1 in the rear of the vehicle 1 in the middle between the left rear wheel 33 and the right rear wheel 34 at the rear behind their axle. The flap 51 is fastened at its front end to the chassis 2 of the vehicle 1 by means of a pivot pin 52 and fastened at its rear end to the chassis 2 of the vehicle 1 by means of an air piston 53. The flap 51 is provided at its rear end from below with a friction surface 511. The pneumatic system 6 consists of air manifolds 61, load regulator 62, pressure tank 63 of electric air valve 64. The pressure tank 63 is located in the vehicle and connected by air distribution 61 to load regulator 62. Load regulator 62 is connected by air distribution 61

SK 7355 ¥ 1 with an electric air valve 64, which is further connected by an air distribution 61 to an air piston 53 of the mechanical system 5. The electronic system 7 consists of a control unit 72 which comprises an electrical switch located on the dashboard and which is connected to the electric air valve 64. of the pneumatic system 6 by means of electrical distributions 71.

Figure 2 shows the anti-skid device in operation. The device is put into operation by the driver activating the electrical switch of the control unit 72, which then opens the electric air valve 64 via electrical lines 71. This brings compressed air from the pressure tank 63, the pressure of which is regulated by the load regulator 62, to the air piston 53. and it activates by its expansion the rotational movement of the flap 51, which is pressed against the road 4 by its friction surface 511. This creates a frictional force between the vehicle 1 and the road 4, which stabilizes and brakes the vehicle in skidding.

Example 2

The anti-skid device of a motor vehicle according to this example comprises four flaps 51 and is shown in Figures 1 and 4, consisting of an interconnected mechanical system 5, a pneumatic system 6 and an electronic system 7. The mechanical system 5 consists of four flaps 51, four pins 52 and three air pistons 53. The front flaps 51 are fixed to the chassis 2 of the vehicle 1 in the front part of the vehicle 1 between the left front wheel 31 and the right front wheel 32 at the rear behind their axle. The left front flap 51 is on the inner rear side of the left front wheel 31 and the right front flap 51 is on the inner rear side of the right front wheel 32. Both the left front flap 51 and the right front flap 51 are fixed with their front ends to the vehicle chassis 2 by pivot pins. 52 and its rear ends fixed to the chassis 2 of the vehicle 1 by means of air pistons 53, each flap 51 having its own air piston 53. The rear flaps 51 are fixed to the chassis 2 of the vehicle 1 in the rear of the vehicle 1 between the left rear wheel 33 and the right rear wheel 34 at the rear behind their axle. The left rear flap 51 is on the inner rear side of the left rear wheel 33 and the right rear flap 51 is on the inner rear side of the right rear wheel 34.
