Definitions

  • the invention relates to a tricycle consisting of two rear wheels, a frame that holds the rear wheels, a frame with a saddle that is pivotally connected to the frame about an approximately horizontal axis, a front wheel that together with a handlebar is pivotally mounted in the frame about an approximately vertical axis, a drive on the frame for the rear wheels, a first bearing between the frame and frame with an approximately horizontal bearing axis, a first gear wheel, the bearing of which is firmly connected to the frame and to which the Drive acts, a second gear wheel, the bearing of which is fixedly connected to the frame and which can be driven in terms of drive on the rear wheels and can be driven by the first gear wheel via a shaft which contains a universal joint whose pivot point lies on the axis about which the Frame is pivotable relative to the frame.
  • Such a wheel is known from British Patent Specification 1 448 805, Figures 6, 7, 9 and 10.
  • only the mentioned bearing is present between the frame and the frame.
  • means are provided which produce restoring forces when the frame is pivoted relative to the frame in such a way that the frame tends to remain in its position which it assumes when driving straight ahead, or when pivoting into it Position return.
  • the disadvantage of this solution is that the wheel is not very stable due to the presence of only one bearing between the frame and the frame.
  • the frame, and thus the person on it have a more or less strong lateral movement by the means mentioned
  • shock that is annoying or can lead to falling.
  • cornering poses problems because the driver has to compensate for the restoring forces in the in-the-corner curve.
  • the invention is based on the object of designing the above-mentioned wheel in such a way that with simultaneous increase in the stability of the wheel there is no lateral impact when driving over an obstacle with a rear wheel and driving through a curve for the driver, as designed with a two-wheeler.
  • This object is achieved in that a second bearing is provided between the frame and the frame, the pivot axis of which is identical to the pivot axis of the first bearing, and that the bearing between the frame and the frame is free of restoring forces.
  • the second bearing increases the stability of the wheel.
  • the restoring-force-free storage avoids side impacts on the frame or on the driver when driving over an obstacle with a rear wheel. Driving through a curve, in which the driver lies in the curve, is the same as with a two-wheeler. The driver therefore does not have to lie as far into the curve as in the known case, in which he not only has to compensate for the centrifugal forces, but also for the restoring forces.
  • the invention also relates to a motorcycle.
  • the drive mentioned is the motor. Is it on the other hand, a tricycle without a motor, then the drive mentioned is the pedal crank.
  • the approximately horizontal bearing axis expediently runs through the point of contact between the front wheel and the ground.

  • first sprocket be mounted on a first part which is fixedly connected to the frame and that the second sprocket be mounted on a second part which is fixedly connected to the frame.
  • a further development of the invention is that the unit, consisting of the first and the second part, the frame and the other parts seated thereon are fastened to the frame so as to be separable, in particular screwed on.
  • the same unit can be used in each case: the provision of rear wheels of different sizes is easily possible.

  • the rear wheel axis, the pivot axis of the two bearings and the rod of the frame, to which the first and second parts and the other parts connected to them are fastened lie approximately at the same height, calculated from the ground . In this way it is achieved that there is sufficient ground clearance for the shifting gears of a derailleur.
  • the first bearing lies in front of the universal bearing and supports the second part and the frame on the frame or on the first part, the second bearing lying behind the universal bearing and in front of the rear wheel axle and supporting the frame on the first part.

Abstract

Un tricycle comprend deux roues arrière, un cadre qui maintient les roues arrière, un châssis avec une selle reliée au cadre de façon qu'elle pivote autour d'un axe à peu près horizontal, une roue avant montée avec un guidon dans le châssis de façon qu'elle pivote autour d'un axe à peu près vertical, un dispositif d'entraînement monté sur le châssis des roues arrière, un premier palier ayant un axe de palier à peu près horizontal, monté entre le cadre et le châssis, une première roue dentée dont le palier est fixé à demeure au cadre et sur laquelle agit le dispositif d'entraînement, une deuxième roue dentée dont le palier est fixé à demeure au cadre et qui peut entraîner les roues arrière et être entraînée par la première roue dentée par l'intermédiaire d'un arbre contenant un joint articulé dont le point de pivotement est situé sur l'axe autour duquel le cadre peut pivoter par rapport au châssis. Entre le châssis (3) et le cadre (15) est placé un deuxième palier (20) dont l'axe de pivotement est identique à l'axe de pivotement du premier palier (27), et l'accouplement entre le châssis et le cadre est exempt de forces de rappel. Le tricycle est ainsi plus stable que les tricycles connus, et lorsqu'une roue arrière passe sur un obstacle le châssis ne subit pas des chocs latéraux.
