Definitions

  • the present invention relates to a device for launching the engine of a two-wheeled vehicle, and more particularly of a two-wheeled vehicle of the moped type, which can also be driven by means of pedals.
  • pedaling means that the vehicle must be kept on its stand, during pedaling, the rear wheel, initially disengaged, being driven only when the engine is started.
  • the present invention therefore aims to remedy this drawback by providing a launching device by intermittent action, which is easily adaptable to a moped comprising a crankset.
  • the object of this invention is in fact a device which comprises a drive bush mounted to slide on the crankshaft, but integral in rotation with this shaft, which normally connects the latter via a chain transmission to the rear wheel of the vehicle, and means for controlling the displacement of the socket engaging it with a launch system with control intermittent mounted between the crankshaft and the engine crankshaft.
  • the drive sleeve comprises at its end opposite the launching system, two diametrically opposite tenons which allow its engagement with this system only in two well-defined angular positions of the crankshaft.
  • the crankset can be used in the usual way to drive the vehicle in the absence of an engine.
  • the crankset is used in the manner of a starting pedal, or kick pedal, as soon as the sleeve has been moved and brought into engagement with the launching system.
  • control means of the drive sleeve comprise an elastic member pushing the sleeve into engagement with the chain transmission, and mounted on a rod controlled remotely and pivoting to cause the displacement of the sleeve.
  • Such a device is particularly suitable for vehicles with two motorized wheels comprising a gear reduction relay motor block, the drive sleeve moving inside the casing of this block between a pinion of the chain transmission and a toothed sector of the system. launch.
  • the moped equipped with such a device is guaranteed to be easy to start, while retaining the possibilities offered by the crankset.
  • Such a moped can even, if desired, be transformed into a two-wheeled vehicle without pedals if the user so wishes and the legislation allows, without requiring significant modifications.
  • the powertrain group shown in FIG. 1 comprises a reduction gearbox relay engine block mounted inside a casing 1, which is crossed by a bottom bracket shaft 2, the motor 3 and the reduction gearbox relay 4 being arranged on one side and on the other side of this tree 2 but near the latter. It is however understood that the invention is not limited to the power train of this type, but can be used on vehicles having different types of power train.
  • the bottom bracket shaft 2 carries at each of its ends a pedal 6. It further supports inside the casing 1 a toothed wheel 8 connected by a transmission chain 10 to another toothed wheel 12 mounted around a shaft 14 which constitutes the output shaft of the reduction gear relay.
  • the shaft 14 in fact crosses the wall of the casing 1 and is connected, outside of the latter, to the rear wheel of the vehicle by a conventional chain transmission comprising a roller chain 16 and two toothed wheels, one of which only 18 is visible in FIG. 1.
  • the toothed wheel 12 is carried by a ring 20 mounted loosely on the shaft 14, and an ac mechanism unidirectional coupling 22 is mounted between this ring and a pinion 24 secured to the shaft 14.
  • the toothed wheel 8. Is also mounted on the bottom bracket shaft 2 by means of a ring, or nut, 26 mounted idly on this shaft. At its end opposite to the toothed wheel 8 the nut 26 is provided with a front serration of sawtooth 28, in which engages a toothing of corresponding shape carried by the end of a sliding sleeve 30 (fig. 2).
  • the sleeve 30 is slidably mounted around the shaft 2, but is made integral in rotation with this shaft by a pin 32 which is fixed diametrically in the shaft 2 and the two ends of which penetrate into longitudinal slots 34 drilled in the wall of the sleeve 30.
  • a guide sleeve 36 is interposed between the bottom bracket shaft 2 and the sleeve 30 and presses at one of its ends on the nut 26.
  • the vehicle can also be driven by means of the powertrain via a pulley transmission 38 and 40 and belt, not shown, connecting the shaft 42 of the motor 3 to the input shaft 44 of the relay reduction gear 4 (figure 1).
  • the input shaft 44 is itself connected by two reduction gears 45, 46 respectively, to an intermediate shaft 48 secured to a pinion 50 engaged with the pinion 24 carried by the output shaft 14.
  • the shaft intermediate 48 and the pinion 46 are however interconnected by a system disengageable. Indeed, they are connected by means of a pin 49 passing diametrically through the shaft and entering an open recess 51 of the pinion.
  • a pusher 52 acting on a fork 54, makes it possible to move the pinion 46 along the shaft 48 against the action of a spring 56, and thus to make the shaft 48 and the pinion 46 free to rotate. one over the other. On the contrary, in the normal position, the spring 56 keeps them integral.
  • the launching of the motor is obtained by means of a toothed sector 58 carried by a nut 60 mounted madly around the bottom bracket shaft 2, on the side of the bush 30 opposite to the toothed wheel 8.
  • the opposite faces of the nut 60 and of the sleeve 30 comprise, one two notches 62 and the other two tenons 64, of corresponding shapes and also diametrically opposite, which are capable of penetrating the notches when the sleeve 30 has moved along the '' bottom bracket 2.
  • the toothed sector 58 further carries a pin 66 fixed to the end of a spiral spring 68 whose opposite end is fixed to the casing 1 itself.
  • the toothed sector 58 is further engaged with a pinion 70 carried by a shaft 71 which passes through the casing 1. Outside this casing the shaft 71 is connected, by means of a pin 73 fixed on it , to a ring 74 carrying a toothed sector 75.
  • the ring 74 has internal helical grooves into which the ends of the pin 73 penetrate. Furthermore, this ring 74 is momentarily immobilized in rotation by a spring 76, the end of which the curved mite is held by the casing 1 in the rest position shown in FIG. 1.
  • the movement of the toothed sector 58 is limited by two end-of-travel stops, respectively 82 and 84, carried by a plate 86 fixed to the motor housing, parallel to the sector 58.
  • the position of the sleeve 30 is controlled by an elastic device which normally maintains it in engagement with the nut 26.
  • This elastic device comprises a spring or fork 88, the curved ends of which enter a groove 89 delimited by two ribs circulars 90 of the outer surface of the sleeve 30.
  • the spring 88 is wound on a rod 92, which is substantially perpendicular to the bottom bracket shaft 2 and projects outside the casing 1 to be connected, by means of a link 93 and of a rod 94, or of another similar system, to a control member which can be confused with the brake control of the vehicle.
  • the spring 88 is also clamped against a plate 96 integral in rotation with the rod 92.
  • the fork 88 relaxes and pushes the socket 30 in engagement with the nut 26.
  • the pusher 52 can also be released to make the pinion integral 46 and the shaft 48 and thus allow the transmission of the movement of the engine to the rear wheel of the vehicle.
  • the driver of the vehicle will have a quick and efficient launch device while retaining the possibility of training by means of the pedals.
