Definitions

  • the invention relates to a conversion kit for a two-wheeled scooter according to the preamble of claim 1.
  • Two-wheeled scooters have a swing arm in their end region, which is pivotably mounted on the scooter frame.
  • This rocker is supported at its free end by a spring strut on the roller frame.
  • This rocker carries the entire drive mechanism, consisting of a drive motor, possibly a gear and drive shaft, which supports the drive wheel.
  • Some driving skill is required to drive such a two-wheeled scooter, in particular when driving in curves and on uneven terrain.
  • the object is to provide a conversion kit which makes it possible to convert a two-wheeled scooter into a three-wheeled scooter.
  • Fig. 1 is a side view of a subframe
  • Fig. La is an end view of the subframe in the direction of arrow A of Figure 1;
  • Fig. 2 is a side view of a cross member
  • FIG. 2a shows an end view of the cross member in the direction of arrow A according to FIG. 2;
  • FIG. 3 shows a side view of an auxiliary rocker
  • ORIGINAL DOCUMENTS 3a shows an end view of the auxiliary rocker in the direction of arrow A according to FIG. 3;
  • Fig. 4 is a plan view of the conversion kit mounted on the scooter and
  • FIG. 5 shows a side view in the direction of arrow B according to FIG. 4.
  • roller frame 1 has two mounting holes 2, via which the rocker arm 3 is pivotally attached via bolts in the two-wheeled scooter.
  • This rocker 3 carries the motor 4 and the entire drive unit with the drive shaft 5, which carries the drive wheel 6.
  • a spring strut runs between the scooter frame 1 and the swing arm 3.
  • the conversion kit has an auxiliary frame 7 and an auxiliary rocker 8 and, if appropriate, a cross member 9.
  • the rocker arm 3 is removed from the frame 1 and the auxiliary frame 7 is fastened to the roller frame 1 by means of the screw bolts 10 via the fastening bores 2.
  • the auxiliary frame 7 has two tabs 11 provided with bores. The distance between the tabs 11 is chosen so that a screw connection with the existing mounting holes 2 of the roller frame is easily possible.
  • two further tabs 12 are provided, which are also provided with bores.
  • the rocker 3 can be attached to the subframe 7.
  • the distance between the tabs 12 is selected so that the rocker 3 can be pivotally attached to the subframe 7 by means of the bolt 13 without modifications.
  • the subframe has two further tabs 14 provided with holes.
  • the auxiliary rocker 8 can be pivotably attached to these tabs 14.
  • This rocker 8 supports at its free end an axis 16 which serves to support the third wheel 17.
  • the cross member 9 is fastened to the roller frame 1 parallel and at a distance from the auxiliary frame 7.
  • the cross member 9 each has two tabs 17 provided with bores.
  • the upper ends of two spring legs 19 are pivotally connected to the brackets 17 by a bolt 18, the lower ends of which are pivotally attached to the rocker arm 3 and to the auxiliary rocker arm 8 by bolts 20.
  • rocker arm 3 and auxiliary rocker arm 8 are pivotably mounted separately from one another about the bolts 13, 15 on the auxiliary frame 7 and are supported on the cross member 9 via the spring struts 19.
  • the wheel 6 is driven while the wheel 17 is free-running. It is also possible to drive the wheel 17 by a connection between the drive shaft 5 and the axle 16.
  • the cross member 9 connected to the roller frame 1 can be screwed or welded to this roller frame 1.
  • the bores which are used in a two-wheeled scooter to support the spring strut are preferably used to screw the cross member 9 to the frame 1.
  • the drive wheel 6 has a brake. It is also possible that the third wheel 17 is additionally provided with a brake.
  • the drive shaft 5 and the axis 16 preferably have the same distances from the longitudinal axis 21 of the roller.

Abstract

Pour transformer une motocyclette à deux roues en motocyclette à trois roues, il est prévu un cadre auxiliaire (7), fixé sur le cadre (1) du véhicule à la place du bras oscillant (3). Ledit bras oscillant (3) qui sert de support au moteur (4) et à la roue motrice (6) est fixé pivotant sur le cadre auxiliaire (7) par l'intermédiaire d'une goupille (13). A l'extrémité opposée du cadre auxiliaire (7), ce dernier supporte un bras oscillant auxiliaire (8), par l'intermédiaire d'un axe (15), qui supporte quant à lui la troisième roue de la motocyclette à trois roues, par l'intermédiaire d'un essieu (16). Le bras oscillant (3) et le bras oscillant auxiliaire (8) s'appuient, par l'intermédiaire de jambes de force (19), sur un élément transversal (9) relié au cadre (1) de la motocyclette.
