Definitions

  • This invention relates to an anti-aquaplaning device for vehicles in general and for airplanes. More particularly, this invention relates to a device of the type mentioned above which is capable, when in operation, of avoiding in case of necessity the typical drawbacks of the aquaplaning phenomenon, so improving substantially on the safety of the user.
  • aquaplaning is the phenomenon consisting in the loss of grip between the wheels of the vehicle and the roadway because of the formation of a film of water between the tire and the roadway asphalt in case of ride on a wet roadway.
  • the Applicant has invented an anti- aquaplaning device suitable for any type of vehicle or of airplane, the latter being provided with landing wheels, said device being capable of preventing the water film under the tires of the vehicle itself from being formed.
  • an anti-aquaplaning device for vehicles in general as well as for airplanes, said device comprising means for removing water from the roadway in front of a wheel; means for coupling said water-removal means to the structure of the vehicle, said coupling means being capable of absorbing any change in the attitude of the vehicle itself as well as any changes on the vertical plane of the road; means for the insertion/ disinsertion of said means for removal of water into the operative or the inoperative position; and means for controlling said insertion/disinsertion means.
  • said means. for removing water can be made up of a rod, which preferably consists of fibres or of steel and is coupled in a fixed or in a removable way to said coupling means.
  • the rod of the device according to the present invention when consisting of steel can have a Teflon sliding block or runner at its end which in the operat- ive position is in contact with the roadway, said runner being connected to the rod itself in a fixed or a remov ⁇ able way.
  • said coupling means can be provided on the chassis of the vehicle or on the suspensions of the same.
  • said insertion/dis- insertion means can be made up of a pneumatic cylinder, the free end of the stem of the same being pivoted on said coupling means, said cylinder being pivoted at the other end on the chassis of the vehicle and being driven through a vacuum reservoir whose operation is controlled by a solenoid valve.
  • said insertion/disinsertion means can be made up of mechan ⁇ ical means, electromechanical means or magnetomechan- ical, electrohydraulic, electronic-pneumatic, electro- pneumatic or electronic-hydraulic means.
  • control means of the device according to the present invention will be preferably provided inside the passenger compartment, and in particular on the steering wheel, and they can consist of a mechanical device, or of an electronic device, or an electromechanical, infra- red remote control, ultrasonic remote control device and so on.
  • the employment of the anti-aquaplaning device ac ⁇ cording to the present invention reduces the need for deeply engraved tires like those employed at the present time in order to reduce the aquaplaning phenomenon.
  • Figure 1 is a schematic view of an embodiment of the device according to the present invention.
  • Figure 2 is a schematic view of the front portion of a vehicle on which the device of Figure 1 is assembled.
  • the kind of embodiment of the device according to the present invention illustrated in Figure 1 is to be considered as illustrative but not as limitative, because, as is obvious, different applied technical sol- utions can be provided according to the type of the vehicle and to the particular requirements, said embodi ⁇ ment providing a rod 1 which consists of fibres or of steel, whose lower end, which is in contact with the roadway, if made up of steel is provided with the slid- ing block or runner mentioned above, which can be realized employing Teflon.
  • said rod 1 is provided with a rapid connection 2 for realizing the coupling of the rod with the supporting structure and with the structure that compensates for changes in the attitude, as well as for rapidly substituting the rod in case of wear or of breaking.
  • the supporting structure of the rod 1 is provided with a shaped member 3 which is connected at one end to the connection 2 and is centrally pivoted on an articu ⁇ lated joint 4 arranged on the chassis of the vehicle and, at the other end, is pivoted on the end of the stem 5 of the piston of the cylinder 6.
  • the cylinder 6, comprising in its inside part a return spring (not shown), is pivoted in turn on the r. ⁇ articulated joint 7 with the chassis of the vehicle.
  • the cylinder 6 is driven as a result of the switch ⁇ ing of an electric valve 8 which is controlled from the inside of the vehicle, said valve allowing the connec- tion of the cylinder 6 to be realized with the vacuum reservoir 9 which in turn is connected, through the connection pipe 10, with the suction manifold (not shown), a valve 11 being interposed for return and adjustment of the vacuum.
  • the device according to the present invention is in ⁇ serted into the operative position by means of a controlled action on the part of the driver, so that said rod 1 is taken into the position shown in Figure 1, whereas in case of dis-insertion the stem 5 is pushed outwards of the cylinder 6 so that the shaped member 3, through rotation about the joint A, causes the rod 1 to lift.
  • Figure 2 shows the positioning of the device accord ⁇ ing to the present invention on a vehicle 12. Said device is provided before each one of the front wheels 13, at such a distance as to avoid any inter ⁇ ference between the rod 1 and the wheel 13.
  • the device can be applied to the non-suspended masses, and in particular it can be applied just to the axle itself.
  • the part concerning the insertion and disinsertion of the device according to the present invention can be realized, differently from the solution shown in Figure 1, with a mechanical, or electromechan ⁇ ical, magneto echanical, electr ⁇ hydraulic, electronic- pneumatic, electropneumatic or electronic-hydraulic devices.
  • the rod 1 is preferably made up of fibres because of its mechanical properties, and in particular because of its flexibility at 3° or 40°, the sizes and the shape of its cross section, its hysteresis, its length, its hardness, its specific weight, its wear resistance, its resistance to mechanical stresses as well as to the ozone contained in the atmosphere and to the salt spread on roadways in winter, and the capability of minimizing the noise when in contact with the asphalt of the road ⁇ way.
