    -1 Two-wheeled vehicle and method for operating a two-wheeled vehicle
    Technical area
    The present invention relates to a two-wheeled vehicle, in particular e-bike, pedelec or the like.
    The present invention relates to a method for operating a two-wheeled vehicle, in particular e-bike, pedelec or the like.
    Although the present invention is generally applicable to any two-wheeler, the present invention will be described with respect to an e-bike or pedelec.
    State of the art
    The term "e-bike" and "pedelec" means two-wheeled vehicles in the form of bicycles that can support the driver with an electric drive. In a pedelec the electric drive is only switched on as long as the driver operates the pedals. With an e-bike, the electric drive helps the driver, even when he is not pedaling, whereby he switches off automatically at a certain maximum speed. It has also become known to operate other components in addition to the drive, for example to perform a braking intervention.
    From the document JP 2005 - 35 502 A it is known to fill a tank on a bicycle with compressed air depending on braking actions. To compressed air
    For other applications besides having the filled tank, a pump can also be provided which supplies compressed gas.
    Document US 6,508,324 B1 discloses a vehicle which is driven by means of a regenerative pneumatic system. For this purpose a pneumatic reservoir in the form of a tank is provided in the vehicle, which is filled by a compressor module.
    It is an object of the invention to provide an accumulator device on a two-wheeled vehicle which can be filled by means of the drive of the two-wheeled vehicle.
    Revelation of the invention
    To achieve the object, the invention provides in one embodiment a two-wheeled vehicle, in particular e-bike, pedelec or the like, comprising a drive unit for driving the two-wheeled vehicle, and a pressure storage device with a pressure accumulator for storing and delivering energy, wherein the drive unit can be connected to the pressure storage device and energy can be stored in the pressure storage device when the drive unit operates.
    In another embodiment the invention provides a method for operating a two-wheeled vehicle, in particular e-bike, pedelec or the like, wherein the two-wheeled vehicle is driven by means of a drive unit, and wherein by means of a pressure storage device with a pressure accumulator for storing and releasing energy, a control device for the two-wheeled vehicle is operated, the drive unit being releasably connected to the pressure storage device and
    Wherein energy is stored in the pressure storage device by means of the drive unit.
    An advantage thereby obtained is that by means of the pressure storage device or additional pressure reservoir or pressure storage is obtained, which can be used for obtaining mechanical energy, for example for active brake intervention, an active suspension, an active seat post, active control intervention and / or a active tire pressure monitoring system by means of a corresponding operating device. In other words, with the aid of the pressure accumulator, in particular but not exclusively, brakes, seat posts, steering equipment, suspensions and / or tire pressure can be regulated. Another advantage is that no additional drive is required to operate the pressure storage device. This not only saves weight, but is also cost effective. Moreover, the wiring can be minimized.
    Further features, advantages and further embodiments of the invention are described below or will become apparent.
    According to an advantageous embodiment, the pressure storage device comprises a hydraulic pressure accumulator and / or a pneumatic pressure accumulator. One of the advantages of a pneumatic pressure accumulator is the simple and reliable operation and the simple implementation. The advantage of a hydraulic pressure accumulator is that large forces can be supplied in a simple manner that can be accurately dosed.
    According to a further advantageous embodiment, the pressure storage device comprises a pump unit which is adapted to fill the pressure accumulator. This can be filled in a simple way, the pressure accumulator.
    According to a further advantageous embodiment, a closed by-pass element,
    -4 in particular a chain and / or a belt for driving at least one wheel. In this way, a reliable and simple drive of at least one wheel can be provided by means of the drive unit.
    According to a further advantageous embodiment, the pressure storage device can be operated by means of the bypass element. The pressure storage device can thus be operated in a simple manner.
    According to a further advantageous embodiment, a tapping device is provided for the bypass element, which can be connected to the pressure storage device for its operation. This can be done in a simple manner, for example by connecting afterwards to an existing drive system of a two-wheeled vehicle.
    According to a further advantageous embodiment, the tapping device comprises a tapping element in the form of a support element of the by-pass element, in particular in the form of a pinion of a chain and / or a coupling. The pressure storage device can be coupled to the drive in a simple manner as required by means of a coupling. The advantage of a support element of the by-pass element is that it is generally already present anyway. Additional components are avoided in this way.
    According to a further advantageous embodiment, the tapping element is adapted to tension the by-pass element. In this way, the number of further components for the pressure storage device and its operation can be further minimized.
    According to a further advantageous embodiment, the tapping device comprises a second by-pass element for operating the pressure storage device. It
    The advantage here is the greater flexibility, because the second by-pass element can be connected or arranged virtually freely with the drive. The second by-pass element can be designed as a chain and, on the one hand, be connected to the pressure storage device on the other hand to one or the tap element of the tap device for its operation.
    Further important features and advantages of the invention will become apparent from the subclaims, from the drawings and from the accompanying figure description with reference to the drawings.
    It is clear that the above mentioned and yet to be described characteristics can be used not only in the given given combination, but also in other combinations or alone, without going beyond the scope of the present invention.
    Preferred embodiments and embodiments of the invention are illustrated in the drawings and will be explained in more detail in the following description, wherein the same reference numerals refer to the same or similar or functionally identical components or elements.
    Brief description of the drawings
    It shows
    Figure 1 shows a two-wheeled vehicle according to an embodiment of the present invention.
    Embodiments of the invention
    Figure 1 shows a two-wheeled vehicle according to an embodiment of the present invention.
    Figure 1 shows a side view of a bicycle. Of course any type of bicycle is conceivable here, for example a city bike, a touring bike, a mountain bike or something similar. The bicycle 1 has a front wheel 2a and a rear wheel 2b on a frame 6 with saddle 12, the saddle 12 being adapted to be vertically adjustable on a substantially vertical part 14 of the frame 6. The rear wheel 2b is via a chain 7 connected to a pedal unit 3 and can be driven by means of the pedal unit 3. The pedal unit 3 comprises an electric motor 4, which is connected to an energy storage 5 in the form of a battery. The pedal unit 3 is also connected to the frame 6. The direction of rotation of the chain 7 in Figure 1 is clockwise. Between the rear wheel 2b and the pedal unit 3, the chain 7 runs clockwise via a pinion 8. The pinion 8 is connected to a pump 9, with which a pressure accumulator 10 is filled with a pressure medium. The pinion 8 can in addition thereby serve to tension the chain 7. In an alternative embodiment, a further second pinion 8 can be provided to drain the force of the chain 7 to drive the pump 9 and thus fill the pressure accumulator 10. Moreover, by further acceleration of the electric motor 4 and an additional chain, the pump 9 and thus the pressure accumulator 10 are filled. The second gear can then be provided next to a drive pinion on the pedal axis of the pedal unit 3. The pressure accumulator 10 then provides a corresponding pressure for further applications. For example, pressure lines run in the frame 6 to the brakes 13 on the front wheel 2a to enable an active brake intervention, for example by additional pressure increase. These pressure lines can be used, for example, for an ABS bicycle to enable active braking on the front wheel and / or on the rear wheel.
    To fill the pressure accumulator 10 with the aid of the pump 9, e.g.
    -7 electric motor 4 in a pedal movement of the rider, preferably operated at a correspondingly higher torque, so that a rider does not feel an effective loss of torque from the pedal unit. 3 If no pedaling is performed, electric motor 4, with a lower rotational speed than what would be sufficient for driving, can drive the rear wheel 2b, the pump 9 for filling the pressure accumulator 10. Moreover, for example, the kinetic energy of the bicycle 1 can be used, for example in a descent, in which the rear wheel 2b drives the chain 7, in which case a freewheel is locked in the rear 2b and with a freewheel of a driver, so that the pedals of the pedal unit 3 do not rotate.
    In summary, at least one embodiment of the invention has at least one of the following advantages:
    • Easy implementation • Cost effective implementation • Lightweight • Higher flexibility
    Although the present invention has been described in terms of preferred embodiments, it is not limited thereto, but can be modified in various ways.
