Abstract

The method involves receiving a measured value of a measured variable with a sensor, and evaluating the measured value to detect, whether a dangerous situation exists. A fluid stream, particularly gas stream (8), is guided on a position of subsoil (10) in front or next to front wheel (2) or rear wheel (4) of a motorcycle (1), if a dangerous situation is detected. A gas generator (6) is activated, if the dangerous situation is detected, where that gas out-flowed from the gas generator forms a part of the fluid stream, particularly the gas stream. An independent claim is included for a motorcycle with a stabilizing device.

Description

The invention relates to a method for stabilizing a motorcycle while driving on a ground and a motorcycle.

Motorcyclists are at risk of traffic accidents due to the lack of crumple zone. The number of motorcyclists killed in traffic accidents stagnates and has hardly changed in the last 20 years. During the same period, however, the number of car occupants killed in traffic accidents was greatly reduced. There is therefore a need to protect motorcyclists more in traffic accidents and thus to reduce the number of motorcyclists killed in road traffic.

From the DE 10 2008 011 577 A1 a method for stabilizing motorcycles is known in which in the event that a dangerous situation is detected, reduces the brake pressure on the front wheel and the motorcycle is so stabilized. However, this naturally only works if the front wheel also brakes. Otherwise, the brake pressure can not be reduced.

One of the main causes of deadly motorcycle accidents is an unadapted high speed to the driving situation. In particular, in curves, it can come in this situation to slipping at least one of the wheels of the motorcycle. Then catching a motorcycle and preventing an accident requires extremely quick reaction and high driving skills.

In many situations, the driver-selected speed for a given curve has initially been correctly estimated in terms of the curve and the driving situation. Nevertheless, the road conditions and thus the friction conditions between the tires of the motorcycle and the surface of the surface to be traveled can change suddenly and unexpectedly and especially for the driver of the motorcycle unfavorable. For this new driving situation, which can occur completely unexpectedly and unpredictably for the driver of the motorcycle, the speed, which was selected by the driver for the curve, however, clearly too high.

Such friction-reducing influences occur in the curve areas mostly due to contamination. These soils can be, for example, wet leaves, generally dirty roads, sand, grit or other contaminants. Simple occurrence of moisture, such as puddles or wet spots on the road surface, can lead to a loss of friction between the tires of the motorcycle and the traveled surface and thus cause the partially fatal accidents.

The present invention has for its object to provide a method for stabilizing a motorcycle while driving on a surface and a motorcycle, with which stabilized in these situations, the motorcycle and a safe ride is possible.

• a) Aufnehmen wenigstens eines Messwertes wenigstens einer Messgröße durch wenigstens einen Sensor,
• b) Auswerten des wenigstens einen Messwertes dahingehend, ob eine Gefahrensituation vorliegt,
• c) Leiten eines Fluidstroms, insbesondere des Gasstromes zumindest auch auf eine Stelle des Untergrundes vor und/oder neben einem Vorderreifen und/oder einem Hinterreifen des Motorrades, falls eine Gefahrensituation erkannt wurde.

The invention achieves the stated object by a method for stabilizing a motorcycle while driving on a subsoil, the method comprising the following steps:

• a) recording at least one measured value of at least one measured variable by at least one sensor,
• b) evaluating the at least one measured value as to whether a dangerous situation exists,
• c) passing a fluid stream, in particular the gas stream, at least also to a location of the ground before and / or next to a front tire and / or a rear tire of the motorcycle, if a dangerous situation has been detected.

A dangerous situation within the meaning of the present invention is always given when the front tire of the motorcycle and / or the rear tire of the motorcycle breaks laterally and slips away. The invention is based on the finding that the danger situation caused thereby is to be ended if the contamination responsible for slipping on the traveling surface is eliminated as quickly as possible.

As already stated, the friction between a tire of the motorcycle and the traveled ground drastically decreases when there is a corresponding contamination on the ground. This leads to slipping of the respective tire. In order to restore the friction between the tire and the driven ground necessary for a stable and safe driving, it is advantageous to ensure that in the area of the ground which is next traveled by the tire, the impurities that the friction loss caused to be eliminated.

For this purpose, according to the invention, a fluid flow, in particular a gas flow, is conducted at least also to these points of the ground. At the location of the ground in front of and / or next to the front tire and / or the rear tire according to the invention therefore is a point of the ground at which the respective tire will still be in the course of the journey. Whether the tire slips or rolls to this point or moves through a combination of both types of movement to this point is irrelevant. The fluid stream, which is passed according to the invention to a location on the ground, can be a gas stream or a liquid stream. A fluid flow, which consists of a combination of a gas and a liquid, is conceivable.

Due to the inventive conduct of the fluid flow to these points of the ground, the possibly existing at these points pollution of the traveled ground is eliminated, so that the necessary for a stable ride of the motorcycle friction between the front tire and the rear tire of the motorcycle and the traveled surface is restored ,

It has proven particularly advantageous if a gas generator is activated if a dangerous situation is detected, wherein the gas flowing out of the gas generator forms at least part of the fluid flow, in particular of the gas flow. Gas generators are known, for example, in the field of airbag technology. The airbag can be, for example, a cold gas airbag. The gas generators used in these airbags are able to store a gas under very high pressure of, for example, 500 bar, and deliver it within a few milliseconds, as long as the gas generator is activated. In this way, a particularly fast and high pressure leaking fluid flow is achieved, which is sufficient to remove the impurities from the surface to be traveled in a very short time, so in particular in good time.

In addition to the described cold gas generators and pyrotechnic gas generators can be used. These are in particular adjustable so that they are able to generate a uniform amount of gas over a relatively long period of time, which is sufficient in particular for eliminating the dangerous situation, and thus, if necessary with the admixture of ambient air, to be directed onto the roadway. Here are all types of pyrotechnic propellants conceivable. From the airbag technology so-called hybrid gas generators are known in which the cold gas technology and pyrotechnics are combined. Alternatively or additionally, the required amount of gas can also be generated by a pressure compressor, ie a compressor.

Advantageously, the at least one sensor is used to determine a steering angle and / or a longitudinal acceleration and / or a transverse acceleration and / or a yaw rate and / or a roll rate of the front tire and / or the rear tire of the motorcycle. In this case, yawing means a rotation of the motorcycle or the front and rear tires of the motorcycle about its vertical axis, which extends in the vertical state of the motorcycle so in a vertical direction, while rolling a rotation about the longitudinal axis of the motorcycle, ie from extends rearward forward, designated. Of course, it is preferably provided that it is possible to determine as many of these variables as possible in order to determine as surely and optimally as possible whether a dangerous situation exists. In an algorithm that determines this, engine data, such as the current speed, and transmission data and braking data can also be incorporated.

Particularly preferably, from the steering angle and / or the longitudinal acceleration and / or the lateral acceleration and / or the yaw rate and / or the roll rate, a location on the ground is determined which the front tire and / or the rear tire will pass during the journey. In this case, at least also at this point, the fluid flow is passed. In this case, an accurate determination of these points on the traveled surface of advantage. The more accurate the location where the tire will be at a later time during travel, the smaller the location at which the fluid flow will be directed. For example, because the amount of gas available to the process is limited in a gas generator, a smaller location to which the fluid stream is to be directed means a higher efficiency of the process and thus a safe removal of contaminants from the subsurface. The available gas will therefore be used more efficiently, making the process generally more effective.

In a preferred embodiment of the method, at least part of the fluid flow is formed by the travel wind and / or exhaust gases of the motorcycle. Due to the fact that these gas streams are also used, not only a gas generator is responsible for generating the gas flow or the fluid flow. It can thereby be either made smaller, since for a given to a location of the substrate to be conductive fluid flow only a smaller by the gas generator to be generated additional gas is required, or the gas generator contained in or generated by him amount of gas can be dosed, whereby the Fluid flow applied to the site of the substrate can be maintained longer. As a result, the substrate can be freed of impurities over a longer distance. The airstream and / or the exhaust gases of the motorcycle are advantageously compacted before they are routed to the ground. Thus, it is possible, in particular in the use of the airstream, to allow it to flow through a relatively large inlet opening in the compressor, while the outlet opening, through which the compressed airstream is supplied to the fluid flow, can be made relatively small. This leads to a compression and to an increase in the flow velocity of the Fahrtwindes, so that it can be used efficiently. If the exhaust gases of the motorcycle are at least used for the fluid flow, it may be useful to cool them before use, to prevent damage to the tires by the hot exhaust gases. When using gases that are permanently inevitable while driving, such as the wind or the exhaust fumes of the motorcycle, there is the possibility of this permanently, and not only in the event of dangerous situations on the ground in front of the front tire and / or Apply rear tires. In this way, the surface of at least the easily removable contaminants is freed even in normal driving, so that at least some dangerous situations do not even arise, but can be prevented already preventive.

A motorcycle according to the invention comprises a front tire, a rear tire and a stabilizing device, which is set up to carry out the method according to the invention. In this case, the stabilization device may in particular comprise vehicle dynamics sensors, by which a wide variety of measured variables can be determined. These may include a steering angle and / or a longitudinal acceleration, a lateral acceleration, a slip angle, the yaw rate or the roll rate. The stabilization device preferably comprises a control unit or a central trip unit, which receives the data thus determined and decides via an algorithm whether or not there is a dangerous situation. In the event that the central trip unit identifies a dangerous situation, the stabilizing device advantageously comprises a gas generator, which may be equipped with a lighter and an opening valve. In order to direct the gas generated by the gas generator in the event of its activation to the desired location, the stabilization device has a gas lance which has a blow-out opening in the region in front of the respective tire of the motorcycle. A gas lance is initially only a pipe or similar device which is suitable for directing the fluid flow to the desired location.

The measurement data recorded by the at least one sensor of the stabilization device is transmitted to the central trip unit and evaluated by an algorithm. The algorithm can be used to determine from the measured values whether a dangerous situation exists. In this case, the central trip unit triggers, for example, the activation of the gas generator. In this case, a gas with a very high pressure and a high flow velocity escapes from the gas generator and is guided by the gas lance to the desired location on the ground. By optimally aligning the exhaust openings of this gas lance with the respective position, any contamination on the roadway is removed from the roadway within a few milliseconds and for a sufficiently long period of time, thereby eliminating the cause of slippage of the respective tire.

In the described method, technologies and sensors are used, with the help of which even very fast processes can be temporally resolved, evaluated and influenced. In particular, the critical driving situations can be detected even on very short time scales. In order to ensure a safe functioning of the method, the triggering algorithms, which decide whether a dangerous situation exists or not, must be made as robust and secure as possible. Thus, the algorithm must be able to distinguish between a hazardous situation and a normal driving situation, although the values provided by the sensors are similar. Thus, for example, no activation may take place when a bump in the road, such as a pothole, leads to a lateral displacement of one of the wheels of the motorcycle. These and similar situations must be clearly recognized by the sensors and classified by the algorithm as a normal driving situation.

Likewise, no activation should occur when the motorcyclist deliberately drifts in a curve. Although this process drifts the rear wheel, which actually corresponds to a critical driving situation, additional information, such as the steering angle, and possibly other information, such as an engine speed, but show that this process was initiated by the motorcyclist active and therefore no danger situation to trigger the system represents. For example, in the case of a deliberate drift through a curve, the steering is hit strongly against the direction of the curve, as a result of which this situation can be distinguished from an unwanted drift in a dangerous situation.

In this way, a large number of situations can be programmed, which are determined by specific sensor values which are not intended to trigger the system. In the same way, many situations can be classified which are to be recognized as a dangerous situation and thus trigger the system.

As an alternative to a gas generator, after the activation and opening of the opening valve, the gas exits uncontrolled from this generator, a gas can also be introduced via a pressure equalization memory in the gas lance and thus form the fluid flow. In this way, the Conditions are controlled in terms of pressure, flow velocity and the duration of the flow process, so that a more controlled method is possible. It is also conceivable to provide at least in addition a liquid tank on the motorcycle. This is then also connected to the gas lance. If it is determined on the basis of the measured values determined by the sensors in the central trip unit that there is a dangerous situation, a valve can be opened, for example, through which the connection between the liquid tank and the gas lance is opened so that the liquid stored in the liquid tank passes through the gas lance is driven out and gets to the ground. This can for example also be done by an aspirator effect. Thus, it is possible, for example, to guide gas generated by a gas generator through the gas lance in the direction of the ground, wherein the gas flows at a high speed under high pressure through the gas lance. In this case, it can be guided past a valve which is in communication with the liquid tank, so that liquid is entrained from the liquid tank through the gas flowing past the valve.

Sensors that are able to sense critical driving conditions with sufficient safety within a few milliseconds and to pass on the thus determined vehicle dynamics parameters to a central control device, for example the central trip unit, are known from the prior art.

Advantageously, the stabilization device comprises a guide device for guiding the fluid flow to the substrate, which comprises a telescopically extendable gas lance. Particularly advantageously, the stabilization device comprises two guide devices, one of which is adapted to direct a fluid flow, in particular a gas flow to a location before and / or next to the front wheel on the ground and is set up, a fluid flow, in particular a gas flow to a point and / or next to the rear wheel to the ground. The guide device is advantageously formed elastically deformable. The gas lance can be designed, for example, in the form of tubes, in particular of telescopically extendable tubes. In this case, for example, the inner telescopic segment is acted upon by the fluid flow with pressure, so that it is extended by means of this fluid flow. The extension of the telescopic gas lance must of course be done within a few milliseconds in order to respond to the occurred dangerous situation in a timely manner. The gas lance comprises an outlet opening through which the fluid stream leaves the stabilizing device and is directed to the desired location of the substrate. This outlet opening is advantageously designed so that the fluid flow strikes the ground with the highest possible pressure and high speed. In particular, the guide device, which is adapted to direct a fluid flow to a point in front of the rear wheel to the ground, is advantageously designed so that the fluid flow is directed almost vertically downwards. In this way, the effect of the fluid flow on contaminants located on the subsurface is maximized. Instead of such a gas lance and a relatively simple pipe construction, for example made of plastic, can be used which has one or more outlet openings or nozzles.

A guide device, which is adapted to direct a fluid flow to a location in front of and / or next to the front wheel to the ground, is advantageously positioned between the tire and the Kotschützer and designed to pivot forward. In this case, a mechanical device may be provided which is lowered in case of need in the direction of the ground, so as to remove impurities from the substrate or at least as far as to crush and detach from the ground that they can be removed from the fluid flow. It has proved to be advantageous if the gas lance is designed to be pivotable about the axis of rotation of the front wheel.

The gas lances are advantageously elastically deformable, so that contact with the ground causes no damage to the gas lance and it remains operational. The outlet openings of the respective guide devices, in particular of the gas lances, can be of any conceivable shape, in particular circular, oval or slot-shaped. It can also be provided a plurality of outlet openings, which are fed by a gas lance. Shape and arrangement of these outlet openings can be optimized for example on the motorcycle type.

The position of these outlet openings is advantageously adjustable and controllable. As a result, the position at which the gas flow has to hit the ground, can be precisely adjusted and adapted to the current situation. In particular, the measured values recorded by the at least one sensor are used for the settings of this position. From them, the current direction of movement of the tire and thus the location is determined, which will be passed during the drive from the tire. As already stated, the stabilization device can be designed such that a fluid flow, in particular a gas flow, is permanently directed to the desired location of the substrate. This can, for example, by appropriately redirected wind, which is optionally previously compressed, and / or exhaust gases exist that are diverted towards the subsoil. Only in case of need, so if a dangerous situation was detected, in addition, for example, a gas generator can be activated. The fact that the gas generator is not responsible for the generation of the fluid flow alone, the fluid flow can be increased overall or the proportion of gas generated by the gas generator can be reduced by a certain proportion. The aim is to extend the period of purging of the fluid stream and thus to clean the substrate over a greater range of impurities. Alternatively or additionally, for example, exhaust gas or wind may also be compressed in an intermediate storage device and supplied to a gas flow generated by the gas generator only when needed.

Consequently, different possibilities are available for generating the fluid flow. In a particularly simple embodiment, the gas stream is caused by a gas generator, which preferably generates cold gas and can be designed in the form of a compressed air reservoir. Alternatively or additionally, the gas may also be generated in a pyrotechnic gas generator. However, this has significant disadvantages due to the high gas temperature.

The corresponding gas generator can be centrally located on the motorcycle, so that the gas flow generated by it can be directed via gas lances both in the direction of the front wheel and in the direction of the rear wheel of the motorcycle. In order to achieve a more controlled emission of the gas stream instead of this uncontrolled discharge of gas, intermediate storage can be provided. In these, for example, the gas released by the gas generator can be recorded and forwarded under reduced pressure to the respective gas lance or the guide device. This makes it possible to extend the duration of action of the fluid flow. In such a buffer, the exhaust gases generated by an exhaust system of the motorcycle or the gases generated by a pressure compressor can be recorded from the wind. As an additional option to increase the gas flow, the outlet opening of the respective gas lance can be designed as a rotary nozzle, so that a gas flow exiting through this outlet opening draws in ambient air to increase the fluid flow (aspirator effect). On the basis of the same effect, it is possible to suck liquid from a liquid tank arranged on the motorcycle, thus also increasing the fluid flow. The individual effects can naturally be combined. In order to be able to conduct the fluid flow emerging from the respective guide device, if possible uninfluenced, ie with as little flow losses as possible to the underground, a wind protection device can be provided which protects the escaping fluid flow from the travel wind of the motorcycle. Such a windshield device can be provided both in guide devices on the front wheel and in guide devices on the rear wheel of the motorcycle.

In the event that a driver of a motorcycle detects a dangerous stretch of road or any other dangerous situation early, the stabilization device can also be configured manually activated.

21 - A motorcycle according to an embodiment of the present invention in different positions during a curve passage.

1 shows a motorcycle 1 according to a first embodiment of the present invention. The motorcycle 1 has a front tire 2 and a rear tire 4 , In the area of the rear tire 4 is a gas generator 6 arranged, which can be activated via a central trip unit, not shown. In this case, flows out of the gas generator 6 a gas stream 8th off, in front of the rear tire 4 on a surface 10 is guided, on which the motorcycle moves.

The motorcycle 1 has at least one sensor, not shown, for receiving at least one measured value, which is evaluated to determine whether a dangerous situation exists. If a dangerous situation is detected, the gas generator 6 activated, so that the gas flow 8th in front of the rear tire 4 to the underground 10 meets. To the gas flow 8th As little disturbing influences as possible due to the airstream are in the direction of travel in front of the gas generator 6 a windbreak 12 intended. This is preferably designed so that it is not activated gas generator 6 is arranged in a folded position from which he is in the in 1 shown position moves when the gas generator 6 is activated.

This in 1 shown motorcycle 1 also has an entrance opening 14 , by the wind in the motorcycle 1 can occur. By a compressor shown only schematically 16 the pressure and flow rate is increased before the airstream as part of the gas flow 8th in front of the rear tire 4 to the underground 10 meets. In this case, for example, between the compressor 16 and the gas generator 6 a valve can be provided, which ensures that the wind only on the case to the ground 10 that a dangerous situation has been identified. In the event that there is no dangerous situation, the inlet opening 14 be formed closable, so that the air resistance of the motorcycle is not adversely affected. Alternatively to this switchable variant, the airstream can also be permanently through the inlet opening and the compressor 16 as a gas stream 8th to the underground 10 be directed.

2 shows the motorcycle 1 according to another embodiment of the present invention. In addition to the already in 1 features shown in the 2 shown motorcycle in the front area over a gas lance 18 , which is shown in the extended state. At the bottom of the gas lance 18 there is an outlet nozzle 20 , This will make another gas flow 8th to the underground 10 passed, but this is in front of the front tire 2 to the underground 10 , The gas lance 18 is over a gas pipe 22 with the gas generator 6 connected so that the two gas flows 8th can be activated together. Alternatively, a valve may be provided through which one or the other gas flow 8th switched on or off, so that depending on whether the front tire 2 and / or at the rear tire 4 a dangerous situation is detected, only in the area of this particular tire 2 . 4 a gas flow to the underground 10 is directed.

3 shows the motorcycle 1 according to another embodiment of the present invention. In the area of the rear tire 4 There is no possibility of a gas flow 8th to the underground 10 to lead. In the area of the front tire 2 is a guide 24 arranged over the gas line 22 with the gas generator 6 connected is. In the event that there is no hazardous situation, the guide is located 24 in an inactive state indicated by a solid line. However, if a dangerous situation is detected, it moves along the arrow 26 in an active position shown by a dashed line, in which the gas flow 8th to the underground 10 is applied. The gas flow 8th is shown in this case in the form of several small gas flows to the largest possible area of the subsurface 10 cover. Folding the guide 24 from the inactive to the active position takes place advantageously by the gas flow 8th passing through the gas line 22 emotional.

4 shows the motorcycle 1 according to another embodiment of the present invention. Both in the area of the front tire 2 as well as in the area of the rear tire 4 is in each case a guide device 24 provided, each via a gas line 22 with the gas generator 6 connected is.

5 shows the motorcycle 1 out 4 , In the area of the front wheel 2 is the guiding device 24 again shown with a solid line in the inactive and with a dashed line in the active state. It can be seen that the guiding device 24 that are in the area of the rear wheel 4 does not need to move to get from an inactive to an active position. Again, the gas flow 8th shown in the form of several small gas streams, which ensures that the largest possible area of the substrate 10 with the gas stream 8th can be applied.

6 corresponds to the illustration 5 in which only the guide 24 in the area of the rear wheel 4 is arranged lower. This will change the path of the gas flow from the baffle 24 to the underground 10 shortened, so the airstream less disturbing influence. In addition, the gas stream 8th to focus better, leaving a smaller spot on the ground 10 can be acted upon by the gas stream.

In 7 is the motorcycle 1 shown again in the area of the front tire 2 and the rear tire 4 via a guide device 24 features, each with a gas line 22 with the gas generator 6 are connected. By the arrow 28 becomes an additional part of the gas flow 8th indicated, which is in the form of a permanent gas flow. This means that this share is independent of any presence of a hazardous situation on the ground 10 is applied. As this part of the gas flow, for example, a part of the exhaust gases or the wind of the motorcycle 1 be used.

8th shows the motorcycle 1 , which is located in the area of the front tire 2 only a gas lance 18 located. In 8th is this gas lance 18 inactive, leaving the outlet nozzle 20 relatively far from the ground 10 is located away.

9 shows the same motorcycle with activated gas lance 18 , It can be seen that the gas lance 18 is formed telescopically extendable, so that in the activated state in 9 the outlet nozzle 20 much closer to the ground 10 located. The gas flow exiting through them 8th , the gas generator 6 is generated, thus hits in a relatively small area on the ground 10 , so here is a good focus and efficient use of the gas flow 8th is reached.

In the 10 and 11 is the motorcycle 1 shown that over two gas lances 18 one of which is in the area of the front tire 2 and one in the area of the rear tire 4 is arranged. In 10 are both gas lances 18 in the inactive state, as well as the gas generator 6 is not activated. 11 shows the situation with activated gas cylinder 6 in which also the gas lances move telescopically, so that the respective outlet nozzles 20 relatively close to the ground 10 so that the gas flow exiting through them 8th well focused on the underground 10 meets. In the area of the gas stream 8th that is near the rear tire 4 to the underground 10 meets, is the windbreak again 12 pictured in the in 10 shown condition to the motorcycle 1 was folded, so that he especially when cornering not disturbing contacts with the ground 10 leads. Of course it is possible the two gas lances 18 separately from each other, in the event that only the front tire 2 or the rear tire 4 a dangerous situation was detected.

The 12 and 13 show the bike 1 with three gas lances 18 in different positions of the motorcycle 1 are arranged. It shows 12 the inactive, 13 the active state.

14 shows the motorcycle 1 with a combination of different configurations for different tires. In the area of the front tire 2 there is a gas lance 18 , through the gas flow 8th to the underground 10 in the area of the front tire 2 is brought. In the area of the rear tire 4 is a swivel nozzle 30 provided by the gas flow 8th in the area of the rear tire 4 to the underground 10 is applied. Because it is a swivel nozzle 30 which is relative to the rear tire 4 is formed pivotable, the gas flow 8th in the area of the rear tire 4 to the underground 10 is also pivoted, so that the position at which he is on the ground 10 meets, is adjustable. This is particularly advantageous if it is not only recognized from the sensor data that a dangerous situation exists, but at the same time also the probable travel path or the current direction of movement of the rear tire 4 is calculated so that the position at which the gas flow 8th to the underground 10 meets, can be adjusted to. The swivel nozzle 30 is in the illustrated embodiment with the gas generator 6 connected via the gas line 22 also with the gas lance 18 connected is.

15 shows a gas lance 18 in the extended state (left) and in the retracted state (right). An inner part 32 on which the outlet nozzle 20 is in the gas lance 18 into or out of the gas lance 18 pushed out. This will make the outlet nozzle 20 closer to the ground 10 or further away from him.

While in the embodiments shown so far, the fluid flow only from the gas stream 8th exist, show the 16 and 17 two motorcycles 1 in which the fluid flow at least also from a liquid flow 34 consists. 16 shows the motorcycle 1 that via the gas generator 6 and those in the area of the front tire 2 arranged gas lance 18 features. About the gas line 22 is the gas generator 6 with a liquid tank 36 connected via a fluid line 38 with the gas lance 18 connected is. Now by the central trip unit of the gas generator 6 activated, this is through the gas line 22 flowing gas is used to move the liquid, which is in the liquid tank 36 located, through the fluid line 38 in the gas lance 18 to press. This will be the gas lance 18 extended and through the outlet nozzle 20 occurs the liquid flow 34 off and get on the ground 10 , In the in 16 As shown, the fluid flow thus consists only of a liquid flow 34 ,

Also in 17 shown motorcycle 1 has only in the area of the front tire 2 over a gas lance 18 , As with all previous embodiments, however, the individual effects and arrangements can easily be combined with one another, depending on where a corresponding device is to be used or needed. In particular, the shape of the outlet nozzle is also 20 to adapt to the respective needs. So it is possible, for example, to design these in a curved design and, for example, on the ground 10 facing side to provide a plurality of openings through which the fluid flow exits. In this way, a particularly large area of the underground 10 be subjected to the fluid flow.

This in 17 shown motorcycle 1 has the gas generator 6 to the one gas line 22 is arranged. However, this is different than in 16 embodiment shown not with the liquid tank 36 but with the gas lance 18 connected. Will the gas generator 6 activated, gas flows through the gas line 22 in the gas lance 18 and ensures that the inner share 32 extends and so the outlet nozzle 20 the underground 10 counter moves.

The liquid tank 36 is over the fluid line 38 with the inner part 32 the gas lance 18 connected. By the activated state of the gas generator 6 Gas flowing through will at least be a part of itself in the liquid tank 36 located liquid through the liquid line 38 aspirated and entrained by the gas stream. In this embodiment, the outlet nozzle 20 Exiting fluid flow thus consists both of a gas stream 8th as well as from a liquid stream 34 ,

Of course, all embodiments are also without gas generator 6 but with another device conceivable, by which a gas flow 8th or other fluid flow to the respective outlet points, for example the gas lances 18 or other guiding devices 24 , is conductive.

The 18a to d, 19a to d and 20a to d each show a schematic side view of a front tire 2 or schematic frontal views of a front tire 2 , The 18a . 19a and 20a each show the same side view of the front tire 2 on which a gas lance 18 located at the lower end of the guide 24 located at the four outlet nozzles 20 are provided. These are each with the numbers 1 to 4 Mistake. In the 18b to d are the gas streams 8th from the outlet nozzles 20 that with the numbers 1 . 3 and 4 are provided when driving straight ahead with the motorcycle 1 shown. It can be seen that different outlet nozzles 20 different areas of the underground 10 cover. Depending on the detected hazardous situation, the outlet nozzles can 20 open and close separately. Optionally, they are also designed to be pivotable, so that it is possible to react individually to the respective detected dangerous situation.

The 19b to d and 20b to d also show the different gas flows 8th coming from the outlet nozzles 20 flow with the numbers 1 . 3 and 4 are provided. In the mentioned figures, however, a cornering is shown. It can be seen that the outlet nozzles 20 are pivotable, so that in different dangerous situations different gas flows 8th the same outlet nozzles 20 to adjust. So show the 19b to d the gas streams 8th at a first dangerous situation, while in the 20b to d gas flows 8th are shown as they correspond to another dangerous situation. It can be seen that in particular the gas streams 8th the outlet nozzles 20 that with the numbers 3 and 4 are provided, are located much further out, than in the corresponding 19c and d.

21 shows the motorcycle 1 in a schematic plan view in different stages of a right turn. One recognizes both the front tire 2 as well as at the rear tire 4 two gas streams each 8th or their projection onto the ground 10 , Bottom right in 21 in the enlarged section you can see the two gas streams 8th on the ground 10 in the area of the front tire 2 of the motorcycle 1 , It can be seen that a gas stream 8th in front of the front tire 2 and another next to the front tire 2 to the underground 10 meets.

It can for the two gas streams 8th different guiding devices 24 or gas lances 18 be provided, or the two gas streams 8th can, as in the 18 to 20 represented by a guide device 24 be applied. In order to be prepared for cornering in each other's directions, is advantageously on both sides of the respective tire 2 . 4 a corresponding possibility provided a gas stream 8th to the underground 10 applied.
