    The present invention relates to a combined engine and pedal drive for a vehicle, in particular watercraft, with a common output shaft for the engine and the pedal drive.
    Combination drives of this type form the basis of a new type of hybrid propulsion watercraft, with an electric motor being used as the engine in particular. The motor drive is mainly used as an auxiliary motor to support the muscle power for the pedal drive, similar to an electric bike with auxiliary engine ("Pedelec").
    The combination of motor and pedal drive in a watercraft makes new demands on the coupling of the two drives, in particular with regard to an unimpaired pedal operation when engine assistance is not desired or not possible. The invention has the aim to provide such a combination drive, which meets these requirements.
    This object is achieved with a combined motor and pedal drive of the aforementioned type, which is characterized according to the invention in that the motor drive via at least a first clutch and the pedal drive via at least one freewheel and a parallel second clutch acts on the output shaft, where a setting TE1 (+43 1) 879 17 06 · FAX, · (+43 1) 879 17 07 · KMATL · MAIL @ PAT1'INTENDK · WEB: WWW.PATENTL.NKT FIRST BANK: 038-56704 BL /: Is provided for the clutches, which has three positions, namely a first position in which the first clutch is closed and the second clutch is open, a second position, in the first and the second clutch are opened, and a third position in which the first clutch is opened and the second clutch is closed.
    The inventive interconnection of clutches and freewheels for the pedal drive allows in the first position a motor-assisted pedal drive, the user can pedal, but does not have to. When the engine is running faster than the pedals, the freewheel comes into play to prevent the pedals from turning faster than the user desires. In the second position, the engine is disengaged and the user can pedal forward supported like a bicycle, without having to drive the idling engine. In the third position, the pedals are rigidly connected to the output shaft so that the user can now reverse to move the vessel in reverse. The engine is also disengaged to prevent inadvertent deployment of the engine drive and a corresponding disturbance of the pedal movement, which could also lead to injury.
    A sequential arrangement of the three positions of the actuator, i. the motor drive position in one edge position, the rigid pedal clutch in the other edge position
    Position and the free-running pedal drive position in the middle between these provides additional security against inadvertent and dangerous engagement or engagement of the motor drive in the rigid coupled position, because this can only be achieved by the bicycle-like freewheeling position.
    Preferably, the adjusting device on a mechanically adjustable control member which controls the first clutch via a first spring connection, wherein the first spring connection opens during the adjustment of the control member from the first to the second position, the first clutch and the adjustment of the second to the third Position the first clutch open under compression of the spring connection. As a result, the clutch travel for engaging and disengaging the motor drive can be kept short, which saves installation space in the clutch housing of the motor drive. In addition, for overcoming the adjusting device from the second to the third position overcoming the spring force of the first spring connection is required, which counteracts an unintentional insertion of the third, rigidly coupled pedal drive position.
    According to a further preferred feature of the invention controls the mechanically adjustable control member via a second spring connection, the second clutch, wherein the second spring connection springs in the adjustment of the control member from the first to the second position against the force of the second clutch biasing in the opening direction biasing spring and at the adjustment of the second to the third position, the force of the biasing spring overcomes and closes the second clutch. As a result, the movement path for the pedal drive clutch is kept short, which also saves installation space there. The biasing spring in the pedal drive clutch also ensures a safe opening of the clutch in any position other than said third position, whereby the risk of unintentional rigid Mitkoppelns the pedal drive in the first and second positions can be reliably prevented by operating errors or disturbances.
    According to a particularly preferred embodiment of the invention, two pedal drives, each with a freewheel and a respective second clutch are provided and the actuator supports a two-armed lever, at the ends of each a second spring connection for controlling a second clutch is articulated. Two pedal drives offer two users the opportunity to pedal. The said two-armed lever, which controls the pedal drive clutches via a respective spring connection, therefore allows a self-adjusting balancing or force distribution from the actuator to the two clutches, which increases the operational reliability.
    It is particularly favorable when the control member can be latched in its three positions by means of a releasable latch, so that unintentional adjustments can be avoided.
    It is particularly advantageous if the freewheel comprises a shaft as the output and a ring gear unidirectionally coupled with it for the pedal drive and the second clutch is a claw disc clutch whose one claw disc is non-rotatably connected to the shaft and whose other claw disc is non-rotatably connected to the ring gear the freewheel and the clutch for the pedal drive can be very compact assembled or integrated.
    The invention will be explained below with reference to an embodiment shown in the accompanying drawings. In the drawings show
    Fig. 1 shows the combined motor and pedal drive of the invention in a perspective view; and FIGS. 2 to 4 a mechanical functional diagram of the combination drive of FIG. 1 in three different operating positions.
    Fig. 1 shows a combined motor and pedal drive 1 for driving a watercraft (not shown), e.g. a pedal boat with auxiliary engine. The combination drive 1 comprises for this purpose a motor drive 2, e.g. a small internal combustion engine or in particular an electric motor, and one or - as shown - preferably two or more pedal drives 3, 4 with pedals 5. The motor drive 2 and the pedal drives 3, 4 act with the interposition of clutches and freewheels, which will be described in more detail later To the output shaft 6, a propulsion unit (not shown) for the watercraft can be flange-mounted in a conventional manner, for example a propeller, a paddle wheel or the like.
    The combination drive 1 could in principle also be used for other types of vehicles than watercraft, e.g. a land or air vehicle, but the control circuit described below is particularly suitable for use in watercraft, which are to be driven by means of the pedal drives 3, 4 optionally also backwards (in the reverse gear).
    Fig. 2 shows the operation of the combination drive 1 of Fig. 1 in detail. The motor drive 2, of which only its output shaft 7 is shown in FIG. 2, acts via a clutch 8 and a summation gear 9 on the output shaft 6 of the combination drive 1. Of the pedal drives 3, 4 in FIG. 2, only the output belt 10, 11, which are driven by the pedals 5 via cranks 12 and pulleys 13 (FIG. 1). The driven belts 10, 11 are guided over one-way clutches ("freewheels") 14, 15 and intermediate shafts 16, 17 to the summation gear 9 and thereby also act on the common output shaft 6 of the combination drive. 1
    The freewheels 14, 15 are formed in a manner known per se as unidirectionally coupling spring ratchet ratchets or ramp-controlled Kleimnrollen 18, 19 in the manner of sleeve freewheels between the driven belts 10, 11 driven ring gears 20, 21 and the intermediate shafts 16, 17. The freewheels 14, 15 couple the pedal drives 3, 4 in the forward direction of pedaling 5 - on the belt 10, 11, the ring gears 20, 21, the ratchets 18, 19, the intermediate shafts 16, 17 and the summation 9 - rotatably with the output shaft 6 and uncouple them in the reverse rotational direction of the output shaft. 6
    The summation 9 is in the simplest case, a rigid transmission coupling between the output of the clutch 8 and the intermediate shafts (outputs) 16, 17 of the clutches 14, 15 with their parallel-shift clutches 22, 23. Thereby acts a rotation of the motor drive 2 via the summation 9 also to the intermediate shafts 16, 17 back, so that the freewheels 14, 15 are also used when the motor drive 2, the shafts 16, 17 rotates faster than the pedal drives 3, 4th
    Each of the freewheels 14, 15 is operatively connected in parallel to each other another ("second") clutch 22, 23. With the aid of the clutches 22, 23, the free-wheeling effects of the freewheels 14, 15 can be disabled, i. the pedal drives 3, 4 are rigidly coupled in both directions of rotation with the output shaft 6.
    The clutches 22, 23 are, for example, claw plate clutches each having a first claw washer 24, 25 and a second claw washer 26, 27 which are axially engageable with each other. The first claw discs 24, 25 are to axially displaceable and rotatably mounted on the shafts 16, 17, whereas the second claw discs 26, 27 rotatably connected to the ring gears 20, 21 or are integral therewith. The first jaw discs 24, 25 are in compression via compression springs 28, 29 in the opening direction, i. biased away from the second jaw discs 26, 27. About ram 30, 31, which engage in circumferential grooves 32, 33 of the axially displaceable claw discs 24, 25, these can be moved in the axial direction and thus the clutches 22, 23 are opened and - against the force of the biasing springs 28, 29 - closed.
    In an analogous manner, the first clutch 8, via which the motor drive 2 acts on the output shaft 6 via the summation gear 9, can be designed as a claw disk clutch with a first claw disk 34 and a second, axially displaceable claw disk 35. The second claw washer is actuated by a plunger 36 to open and close the clutch 8.
    The first and second clutches 8, 22 and 23 could alternatively be realized in any other manner known in the art, e.g. as friction clutches.
    For actuating the clutches 8, 22 and 23, an adjusting device 37 is provided, which has three different operating positions, of which the first in Fig. 2, the second in Fig. 3 and the third in Fig. 4 is shown. The adjusting device 37 comprises a mechanically adjustable control member 38, in the example shown in the drawings to the left and right back and forth displaceable slider with a spring-loaded pawl 39 in the detents 40 (only partially shown) storage rack 41 of the combination drive 1 and Watercraft can engage. On the control member 38, a pull handle 42 is mounted; by lifting the pull handle 42, the pawl 39 can be temporarily disengaged. With the aid of this arrangement, the adjusting device 37 can be latched in each of its three positions (FIGS. 2, 3, 4).
    The control member 38 is connected via a first spring connection 43 with the clutch 8, more precisely, the plunger 36, in connection. Via two further spring connections 44, 45 controls the control member 38, the clutches 22, 23, more precisely the ram 30, 31. The second spring connections 44, 45 may directly on the control member 38 or preferably - as shown - at the ends of a symmetrically mounted on the control member 38 attack two-armed lever 46 to evenly divide the force.
    It is understood that the spring connections 43 to 45 are shown only schematically in FIGS. 2 to 4, u.zw. JE
    IV Weil with a compression spring which acts between two linkage parts, which on the one hand to the rams 30, 31, 36 and on the other hand to the control member 38 and its lever 46 attack. In practice, instead of such linkage parts, any other mechanical drives may also be used, e.g. Bowden cables 48, optionally with steering levers 49, as shown in Fig. 1.
    The mode of operation of the adjusting device 37 will now be explained with reference to its three operating positions shown in FIGS. 2 to 4. In the first, shown in Fig. 2 (left) position of the actuator 37, the clutch 8 of the motor drive 2 is closed and the clutches 22, 23 of the pedal drives 3, 4 are - supported by their compression springs 28, 29 - opened. The motor drive 2 can drive the output shaft 6, and the pedal drives 3, 4 can drive the output shaft 6 via the freewheels 14, 15 in the forward direction. A backward pedaling 5 brings the freewheels 14, 15 are used.
    In the second, middle position of the adjusting device 37 shown in FIG. 3, the clutch 8 of the motor drive 2 has been opened by the spring connection 43. The second clutches 22, 23 of the pedal drives 3, 4 remain open because the springs of the spring connections 44, 45 are dimensioned so that they are weaker than the biasing springs 28, 29 of the clutches 22, 23. In the movement of the actuator 38 of The first in the second position therefore initially spring only the spring connections 44, 45 a. As a result, in the second position, the motor drive 2 is decoupled from the output shaft 6, and the pedal drives 3, 4 act on the output shaft 6 via the freewheels 14, 15. The pedals 5 can be stepped forwardly in order to drive the watercraft forward Backward struts are the freewheels 14, 15 are used.
    In the third, shown in Fig. 4 right position of the actuator 37, the first spring connection 43 - to limit the Axialverschiebeweg the clutch 8 and thereby reduce their installation space - sprung, which keeps the clutch 8 of the motor drive still open. In addition, the spring connection 43 produces a noticeable spring force when moving the control member 38 from the second to the third position, to make the achievement of this third position clearly noticeable to the user. The second spring connections 44, 45 have now been stressed so far that they overcome the forces of the biasing springs 28, 29 of the clutches 22, 23 and these are closed. As a result, the shafts 16, 17 are now rigidly coupled to the ring gears 20, 21, i. the freewheels 14, 15 disabled, and the pedal drives 3, 4 rotatably coupled in both directions with the output shaft 6.
    The pedals 5 can now be stepped in the forward and backward directions to drive the output shaft 6 and thus the vessel both forwards and backwards by muscle power can. The motor drive 2 is in this third • • * * * * * «·· * ·
    Position remains disengaged, so that an unintentional switching on the engine has no effect on the rigidly engaged pedals 5, which could endanger the user otherwise.
    The third position (FIG. 4) is reached by the engaged motor position (FIG. 2) only via the intermediate path of the second position (FIG. 3), which offers additional security against an inadvertent insertion of this position.
    The invention is not limited to the illustrated embodiments, but includes all variants and modifications that fall within the scope of the appended claims.
