Definitions

  • the invention relates to a single-track, motor-driven two-wheeler.
  • Bikes especially those with a high center of gravity, e.g. those with a roof have a relatively large side surface, so that they naturally have a slightly increased sensitivity to side winds.
  • the cross wind can cause the vehicle to yaw and roll. Likewise, it can e.g. B. by luggage at higher speeds to vehicle fluctuations.
  • the object of the invention is to create a single-track motor-driven two-wheeler which compensates for these disadvantages.
  • the single-track, motor-driven two-wheeler according to the invention is provided with laterally attached, projecting flaps which can be adjusted by motor in the ferry mode in such a way that they can generate different lift or downforce, with a control and a sensor system associated therewith, and the control being dependent on external flaps and / or the position of the two-wheeler controls the flaps and stabilizes the two-wheeler on the ground
  • a flap is provided at least on each side, and this flaps laterally from the rest of the body. Due to the mobility of the flaps, they can either be moved evenly left and right or differently left and right and placed in the headwind. On the one hand, this means that there is a different air resistance and / or different upward and downward force on the left and right, with which cross winds can be balanced and upward or downward force can be generated even at higher speeds. The two-wheeler is then more stable.
  • the flaps can also be an advantage when braking, because they are installed, for example, by a motor in order to generate maximum air resistance.
  • the sensors can not only determine ambient conditions such as the cross wind on the left and right of the vehicle or the ambient pressure existing on the left and right due to the different winds, but it also does possible that the driving conditions are determined via the sensors, e.g. B. whether the motorcycle fluctuates or is turned into a corner.
  • Spring deflections would also be detectable, for example to generate lift in the area of the rear wheel when the luggage load is high.
  • the travel speed can also be included in the determination of the flap position.
  • the flaps on the left and right can preferably be controlled differently depending on the sensed data.
  • the flaps can be attached in the front half of the bike and / or behind the driver's seat, which u. a. depends on the center of gravity of the vehicle in the longitudinal direction.
  • the flaps can also be designed so that only downforce and no lift can be generated with them.
  • profiles can be used that only generate lift and no downforce, even when swiveling up and down.
  • the flaps on a stable fastener such. B. attached to the body so that they are held stable.
  • a variant of the invention provides that the two-wheeler according to the invention has a roof and two adjacent, spaced side rails which extend from a frame upwards and backwards to form front and rear pillars which merge into side roof rails.
  • the flaps are attached to the front and / or rear pillars.
  • the pillars are located relatively far out on the vehicle and allow easy placement and attachment of the flaps. In addition, this ensures that the flaps have a good flow of air and develop their effect.
  • the flaps preferably have a pivot axis which, for. B. is provided on the front or rear end portion of the flaps or in between, so that the flaps are pivotable up and down about the pivot axis.
  • the flaps are also shock pads that protrude so far laterally that they act as an impact absorber when the two-wheeler tips over. Two-wheelers that are permitted to be driven without a helmet must meet certain legal requirements in order to keep the head load when the two-wheeler tips over from a standing position. These bumper pads therefore protrude laterally from the rest of the two-wheeler. They have to have a certain damping effect. According to the invention, these shock pads are now simultaneously aerodynamically adjustable flaps.
  • the shock pads have, for example, an outer shell which is filled with a shock-absorbing material, in particular foamed plastic, inside the shock pad, i. H. the outer shell delimits the shock-absorbing material.
  • a shock-absorbing material in particular foamed plastic
  • the control and the sensor system are preferably designed in such a way that one or more of the following properties is generated by the flaps: at maximum speed, the flaps generate the least possible resistance, i.e. H. their position is optimally placed in the headwind; when braking, the flaps have the highest possible air resistance; when cornering, the flaps support the turning and raising of the two-wheeler, which is achieved by different inclinations of the flaps on the left and right of the vehicle, and in crosswinds the flaps stabilize the two-wheeler.
  • the flaps on the left and right are controlled differently.
  • Sensors for determining the environmental conditions are attached to the handlebars, for example.
  • other sensors can also form the entire sensor system and be coupled to the control, as already indicated at the beginning.
  • a so-called 6-axis sensor box can be used as the sensor system, which supplies data in six spatial axes.
  • FIG. 1 shows a schematic view of a variant of a two-wheeler according to the invention
  • FIG. 2 shows a detailed view of the roof of the two-wheeler according to FIG. 1 with a side, adjustable flap,
  • FIG. 3 is a detailed side view of the flap provided in the two-wheeler according to the invention in a basic position
  • FIG. 4 shows three different positions of the flap according to FIG. 3.
  • FIG. 1 shows a single-track, motor-driven (here, for example, battery-operated) two-wheeler 10, with a frame 12 to which the roof 14 is attached.
  • motor-driven here, for example, battery-operated
  • the roof 14 has two side rails 16, 18 running side by side, which define front pillars 22, 24 extending laterally from the front of the windshield 20, then two side roof rails 26, 28 and then rear pillars 30, each with a downward spur rear pillar 30 is attached in the rear region of the frame 12 and a downward extension of each front pillar 22, 24 is also attached to the frame 12.
  • the two-wheeler 10 shown can be driven without a helmet.
  • the two-wheeler 10 has z. B. in the area of the rear pillars 30 at shoulder height laterally projecting flaps 32, which are motor-adjustable about a pivot axis 34, which runs essentially horizontally and transversely to the vehicle longitudinal axis.
  • the rear pillars 30 have integrally molded, protruding side shielding planks 31 which laterally protect the occupant up to the shoulder.
  • the flaps 32 are attached to the side shielding planks 31, preferably at shoulder height. With the high arrangement of the flaps 32, an improved effect of the flaps 32 is achieved.
  • An electric motor 36 is indicated in FIGS. 2 to 4, which is coupled to the pivot axis 34 and to the associated flap 32 in order to be able to pivot it in the direction of the arrow.
  • the two flaps 32 are attached symmetrically to the left and right at the same height and only mirror-symmetrically to the longitudinal center plane on the two-wheeler.
  • Each flap 32 has its own associated electric motor 36. This allows the two flaps 32 to be moved differently.
  • the electric motors 36 are coupled to a controller 40.
  • the controller 40 is in turn fed by a sensor system, for example with a 6-axis sensor box 42 and sensors 44, for example at the outer ends of the handlebar 46.
  • Data such as driving speed, angle of inclination, steering angle, side wind, deflection and the like are determined via the sensor system, one or more of the aforementioned data being detected.
  • the control system uses the data obtained from the sensor system to determine an advantageous position for each of the two flaps 32, so that the two-wheeler has an improved and more stable road holding position and supports the turning and straightening of the vehicle.
  • the flaps 32 can be controlled differently and pivoted differently.
  • FIG. 4 shows three positions of the flap 32, namely a lower position 50, a middle position 52 and an upper position 54. From the lower to the upper position 52-54, more and more downforce is generated by the flap 32. In the present case, the profile shape of the flaps 32 generates downforce.
  • the flap 32 can generate up and down, as required.
  • the side wind sensitivity is reduced with the flaps.
  • the flaps 32 are attached behind the driver's seat 60, but they can also be attached in front of the seat 60, for example on the frame or near the frame, or even on trim parts in the front part of the vehicle.
  • the corresponding flap has the reference number 32 '.
  • This flap 32 ' like the flaps 32, can also be pivoted individually.
  • two flaps 32 ' are attached symmetrically to one another on the left and right.
  • the flaps 32 are also so-called shock pads. This means that they protrude sideways so far that when the two-wheeler 20 tips over, the flaps 32 come into contact with the ground and have a damping action in order to reduce the head load on the occupant and to protect the two-wheeler in the case of helmet-free two-wheelers.
  • the flaps 32 have an outer shell 50 made of preferably impact-resistant and abrasion-resistant plastic.
  • the outer shell is curved outwards and accommodates a shock-absorbing material on the inside which fills the entire interior.
  • the shock-absorbing material is formed in particular by foaming the shell or by an inserted part.
  • the controller 40 and the sensor system are designed so that the flaps produce a low and preferably the lowest possible air resistance at maximum speed, here pivot to position 52, have the highest air resistance when braking, here z. B. at position 50, when cornering support and straightening the vehicle, z. B. by driving the left flap in position 50 and the right flap in position 54 on a left-hand curve, and / or in crosswinds the two-wheeler 10 is stabilized by different positions of the left and right flaps 32.
  • Integration effort creates the possibility of aerodynamics of the two-wheeler 10 Adapting increases driving stability and driving safety, assists in turning in and straightening up when cornering and ensures safety during the "accident test" by optionally also acting as bumper pads.
