The invention further relates to a device for applying anti-slip additives to the tread surface of a motor vehicle by means of a program transmitter, atomizers located in the tread area of the vehicle wheels, electric, mechanical, pneumatic or hydraulic transmission, and a with a signal processing unit having spray tanks integral with the vehicle body mounted sprayer booms, an electromagnetic coil actuating the spray tanks directly or by means of a hoist, a pneumatic or hydraulically actuated cylinder.

The invention relates to a device which automatically or by deliberate action delivers adhesion enhancing fluid to the tread of wheels of slippery vehicles to reduce the risk of accident and material damage caused by slipping, and to increase the vehicle's stability and steerability.

Especially when the weather changes to temperatures below freezing, there are many very serious personal injury and tragedy accidents and serious property damage due to ice, snow, water, sludge, oil spill or slippery vehicles slipping on the road. they spin, they become out of control, they become unstoppable. Such accidents can be prevented or significantly reduced by increasing wheel grip. The adhesion of the wheels can be improved by the structure of the tires, their tread pattern, temporary attachment to the surface of the wheels, particulate matter between the road surface and the surface of the wheels, or by the use of adhesives. Temporary-fit devices mainly work in snow or mud. However, they cannot be used for long distances under normal road conditions, as they make the wheels unbalanced, damage the pulleys and the tire casing.

The rotary electromagnetic actuator described in DE 3 237 763, which is quite difficult to mount on the front of the vehicle, is used for the delivery of particulate materials to road surfaces. A further disadvantage of this structure is that, when cornering, the wheels of the vehicle do not follow the path of the metering wheel, so that even in the most dangerous position, the coarse-graining adhesive is not effective.

The device described in DE 3 417 084 reduces the risk of running water by spraying water with compressed air from the wheels. Its use is made comfortable and safe by automatically engaging when the steering column torque decreases due to a reduction in steering resistance. This equipment is not effective on icy, snowy roads. Another problem is that it only senses the steering wheel slipping, which causes it to be inactive when the vehicle is moving in a straight line, and not at all when the steering wheel slips.

An anti-slip solution described in patent application HU 204 297, which, when exposed to water, creates an adhesion-increasing layer on the tread of the wheels. The spray manufactured by Dimex Ltd., England, has almost the same effect. (Business, Feb. 7, 1992, p. 12). In the prior art, these fluids have been manually sprayed from an aerosol can into the tire tread when the vehicle is stationary. In reality, in many cases, the road surface becomes slippery as the vehicle travels, so you have to stop the wheels talking. On the one hand, this is uncomfortable and, on the other hand, it is not possible to intervene immediately when a slip is detected, and stopping is one of the most dangerous operations.

US 4,789,190 and DE 3 143 311 A1 disclose an arrangement for applying a non-slip material to the tread through nozzles arranged around the circumference of the tread surface of the machine wheels. The anti-slip solution reaches the nozzles from a central fluid reservoir through three-way valves. The valves are operated by a central program transmitter.

The required nozzle pressure is provided by a compressor connected to the upper part of the fluid reservoir.

The disadvantage of this anti-skid system is that the arrangement of the valves does not allow the front and rear bikes to be provided separately when needed.

It is an object of the present invention to provide a non-slip device which provides the tread surface of the front and rear bicycles individually or in combination, and to provide a nipple with a unique anti-slip fluid (e.g. using a spray tank). It happens.

The present invention relates to an apparatus for applying anti-slip additives to the tread surface of motor vehicle wheels by means of a program transmitter, air reservoir, fluid reservoir, atomizers arranged in the tread area of the wheels of the motor vehicle, a central fluid valve connected directly to the fluid reservoir or via a pump, a distribution pipe connected to the central fluid valve, a front fluid valve or a rear fluid valve mounted in a branch of the distribution pipe, the air reservoir and the manifold connecting pipe for cleaning the piping system.

The invention further relates to a device for applying anti-slip additives to the tread surface of a vehicle wheel by means of a program transmitter, atomizers arranged in the tread area of the vehicle wheels, electric, mechanical, pneumatic or hydraulic transmission and a power meter incorporated by

EN 214,079 Β Signal Processing Unit, which is equipped with spray tanks integrated with atomizers mounted on the body of the vehicle, electromagnetic coil, mechanism / bowden, pneumatic or hydraulically actuated directly or by lifting the spray tanks.

The design and operation of the anti-slip device of the present invention is based on the discovery that the effect of wheel adhesion enhancing materials and vehicle stability can be significantly increased by automatically applying the tread wheels simultaneously on the same axle as quickly as possible, adhesive to avoid distracting the driver.

The invention will now be described with reference to the drawings, in which:

Figure 1 is a schematic diagram of an anti-slip fluid injection device operated by compressed air (gas);

Figure 2 is a schematic diagram of a pump-operated anti-slip liquid atomizer;

Figure 3 illustrates a spray arrangement of a slip-reducing fluid atomizer directly assembled with a unique container with a plurality of actuators.

The fluid can be moved with propellant (compressed air, CO ₂ , N ₂ , etc.) or, depending on viscosity, with a pump (centrifugal, gear, diaphragm, piston, etc.). With a low dispersion requirement and low viscosity fluid, the fluid pressure generated by the material transfer system is sufficient for atomization.

The arrangement of the anti-slip liquid atomiser for pneumatic actuation is shown in Figure 1. Nozzles 2 with conveniently replaceable nozzles 1 are disposed above the wheels of the vehicle to which the fluid is conveyed by the distribution pipe 3. The central fluid valve 4 is integrated in the distribution pipe 3. For a more sophisticated two-circuit system, both the 4E front and 4H rear fluid valves are required. The nozzles 2 are secured to the body by means of an adjustable fastening device 5 and protected by a protective bell 6 from contamination. The fluid reservoir 15 containing the anti-slip fluid is placed in front of the central fluid valve 4. Connected to the upper portion of the fluid reservoir 15 is the drive air pipe 21 connecting the air reservoir 17 through the drive air valve 22H. The device can be controlled by switch 9. From the air reservoir 17 with the tire valve 19 and the air filler pipe 20 and the pressure indicator 18, the compressed air which moves the adhesion enhancing fluid is led by the propulsion air tube 21 through the propulsion air valve 22H to the upper portion of the liquid reservoir 15. The vehicle's spare wheel may also form the air reservoir 17 for weight reduction and space saving. In this solution, the air fill tube 20 is to be connected to the spare wheel valve. Compressed air for cleaning the pipeline is fed from the air reservoir 17 through the purge air valve 22T to the distribution pipeline 3 below the central fluid valve 4. It is expedient to install the liquid level indicator 16 in the liquid container 15 and the pressure indicator 18 in the air reservoir 17.

The driver often notices the vehicle slipping late. Acceleration of this "sensing" is achieved by means of an evaluation unit 13 which processes signals emitted by the power meter 10 and the steering displacement sensor 10 and the wheel speed sensor 12 mounted on the wheels of the vehicle, which indicates to the driver by means of by activating the switch 9, anti-slip fluid is applied to the wheel surface.

In order to detect a reduction in wheel adhesion to a critical value, it is necessary to evaluate together the signals provided by the force gauge 10 and the displacement sensors 11 mounted in the steering gear 8.

This slip detection is triggered by rapid steering movements caused by falling steering forces. For smaller vehicles and passenger cars, it may also be sufficient to detect the force exerted on the steering column and the angular velocity (circumferential speed) of the steering column. The force exerted on the steering column can be sensed by means of a strain gauge or piezoelectric principle, and the angular velocity is detected inductively. For power steering vehicles, sensors should be installed between the steered wheel and the servo unit. In this case, the signals provided by the sensors can be more easily transmitted to the evaluation unit 13.

Another way of detecting the slip of the wheels of a vehicle traveling without braking or starting is based on the complex evaluation of signals from the anti-lock braking system (ABS) wheel sensors. At start, the "spin" or sliding wheels of the moving vehicle give a much larger signal than the more gripping wheels. The system's lower limit of sensitivity shall be set so that the system does not yet operate in response to a difference in speed resulting from the difference in the curvature of the outer and inner wheels. One of the advantages of this method is that it can be adapted to the vehicle simply by extending the ABS system already installed and, on the other hand, that the sliding wheel can be visually displayed on the vehicle's dashboard.

In other embodiments, the combination of the above described slip sensing methods significantly increases the sensitivity and reliability of the apparatus. By connecting the program transmitter 7 to the evaluation unit 13, the operation of the device via the switch 9 can also be made automatic. By positioning the switch 9 in different positions, the device can be used for various purposes, e.g. .Automatic "" Routine "" Emergency "etc. operating mode.

In the "automatic" position, the output signal of the evaluation unit 13 is directly transmitted to the program transmitter 7, so that when the wheel adhesion falls to a critical value, you can activate all the carburettors independently of the vehicle driver. This is useful for inexperienced drivers or for moving on a variable grip.

In the "routine" position, the connection between the evaluation unit 13 and the programmer 7 is interrupted, the atomizers

EN 214 079 Β The driver can decide whether to operate according to the desired variations based on the signals from the slip indicator 14 or from his own driving experience. so e.g. with the other positions of the switch 9, the front fluid valve 4E can operate only the front fluid valve 4H, the rear fluid valve 4H only the rear fluid valve, and both valves via the program transmitter 7 on all wheels. This mode allows masters, rally drivers, by deliberately sliding their wheels, so-called. Turn with the powerslide technique.

When set to the "emergency" position, the programmer 7 activates all the carburettors. This can be of great importance in emergency braking on slippery roads.

The switching options described above are e.g. they can be easily implemented with a structure similar to the wiper switch.

The program transmitter 7 controls the operating sequence and the action time of the actuators of the device based on the signals received from the switch 9. This can be used to adjust the spraying time of the wheels at least one revolution or the compressed air blasting of the manifold 3.

Figure 2 illustrates the arrangement of the liquid atomizer in the case of hydraulic actuation. In this case, the anti-slip liquid is supplied by a pump 24 connected to the lower part of the tank 15 via the central fluid valve 4 to the distribution pipe 3. If required by the anti-slip fluid, the system should be vented with air or other gas and the air reservoir 17, the propulsion air pipe 21 and the purge air valve 22T applied.

Figure 3 illustrates a nebulizer arrangement directly assembled with a "Spray" reservoir of the liquid atomiser. 15 / A spray tanks are directly connected to each of the atomisers 2 connected to the body by means of an adjustable fastening mechanism 5 in each car wheel area. They are actuated in various ways, depending on the design of the nebulizer 2. The electromagnetic coil 25 actuated by switch 9 is actuated either directly or by means of a lever 26, a 3 / A mechanism, or a bowden which can be actuated directly by the driver by means of switch 9 or by the program transmitter 7 (Fig. 3). It can operate using the 3B pipeline with air (or other gas) taken from the air reservoir 17, or hydraulically using the 15B hydraulic fluid reservoir and the 24 / A hydraulic pump via the cylinder 27. In the case of pure hydraulic actuation, the operation of the atomiser 2 is controlled by means of a central fluid valve 4 integrated in the pipe 3B, and by a pneumatic actuator valve 22 mounted after the air reservoir 17 in the case of pure pneumatic actuation.

Advantageous properties of the anti-slip device of the present invention are particularly evident in slippery, icy conditions. Even the simplest, relatively inexpensive design, operated by the driver of the vehicle, significantly increases the ride stability and steerability of the sliding vehicle, as it can be used to spray adhesion-enhancing fluid on the tread of the wheels while the vehicle is in motion.

The more sophisticated, automatic versions of the slider and program transmitter, which operate automatically, are not only beneficial but also life-saving for late, inexperienced or panic-aware drivers. The automatic solution can also be advantageously used by experienced drivers when the vehicle runs on slippery roads at relatively high speeds, since increasing adhesion reduces both slip and the driver's hands are free to perform steering maneuvers safely.

In thick, loose snow, deep mud, and dry sand, the under-road strength characteristics determine the effectiveness of the anti-slip device. Because of the sliding layers of the road, the wheels of the vehicle may slip despite the addition of adhesion enhancing fluid. For these road conditions, it is recommended that wheels be fitted with temporary anti-slip devices, chains, rings, etc. applied.

Slippage due to a sudden change of direction during violent driving will reduce the device, but will not provide absolute safety.

In the development of master guides, the apparatus of the present invention is advantageously used to apply routine traps to regain control of a slipped vehicle by applying an adhesive reducing fluid or emulsion (e.g., a water-in-oil emulsion) from the reservoir.

The scope of the anti-slip device according to the invention is greatly increased by the fact that it can be designed and installed not only in new vehicles, but also in retrofitted or used vehicles.
