Abstract

The two wheeled vehicle has an engine between the wheels, and the front wheel only is driven. The drive can be transmitted mechanically, electrically, hydraulically or pneumatically, or by a combination of these types. The drive can, alternatively, be to the rear wheel. It can be possible to offer steering facilities using the rear wheel. The front wheel drive pulls the vehicle for increased cornering ability. There is also an advantage in stability of the vehicle when accelerated harshly.

Description

La présente invention concerne l'adaptation d'une motricité sur la roue
AVANT de véhicules à deux roues à moteur situé entre les deux roues.The present invention relates to the adaptation of a traction on the wheel
FRONT of two-wheeled motor vehicles located between the two wheels.

Dans les véhicules connus à deux roues, à moteur intermédiaire, la motricité est fournie par la roue ARRIERE. Ces engins presentent les inconvénients inhérents à la "propulsion motrice" tels que "cabrage" à l'accélération ou "chassé" en virage du fait de la "poussée" de la roue ARRIERE. In known vehicles with two wheels, with an intermediate motor, the drive is provided by the REAR wheel. These machines have the drawbacks inherent in "drive propulsion" such as "nose up" when accelerating or "chased" when cornering due to the "thrust" of the REAR wheel.

L'adaptation selon 1 'invention, d 'une motricité AVANT, permet d'éliminer presque totalement ces incovénients. En effet, la motricité de la roue AVANT qui "tire" l'engin, en particulier au démarrage et en virage, compense l'effet du couple de renversement, augmente l'adhérence, donc la tenue de route. The adaptation according to the invention, of a motor skills BEFORE, makes it possible to almost completely eliminate these disadvantages. Indeed, the traction of the FRONT wheel which "pulls" the machine, in particular at the start and in cornering, compensates for the effect of the overturning torque, increases the grip, therefore the road holding.

L'obtention de cette motricité AVANT à partir d'un élément moteur central peut faire appel aux différentes techniques de transmission d'énergie utilisées de nos jours
- transmission mécanique,
- transmission électrique,
- transmission hydraulique,
- transmission pneumatique.Obtaining this FRONT motor skills from a central motor element can call on the various energy transmission techniques used today.
- mechanical transmission,
- electrical transmission,
- hydraulic transmission,
- pneumatic transmission.

L'appropriation d'organes intermédiaires et périphériques-devra se faire selon le type de transmission utilisée. The appropriation of intermediate and peripheral organs must be done according to the type of transmission used.

De plus, les formes, dimensions et dispositions des différentes éléments pourront varier dans la limite des équivalents, comme d'ailleurs, les matières utilisées pour leur fabrication sans changer pour cela la conception générale de l'invention qui vient d'être décrite. In addition, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, as, moreover, the materials used for their manufacture without thereby changing the general design of the invention which has just been described.

Les dispositifs, objets de l'invention, peuvent être utilisés sur tous les types de véhicules à deux roues dont le moteur est situé entre les roues. The devices, objects of the invention, can be used on all types of two-wheeled vehicles whose engine is located between the wheels.

Par le supplément d'adhérence apportée, ils contribuent d 'une part à une augmen- tation du rendement et des performances, d'autre part à une amélioration de la sécurité des utilisateurs, en particulier sur les engins à vocation "tout terrain". By the additional grip provided, they contribute on the one hand to an increase in yield and performance, on the other hand to an improvement in the safety of users, in particular on "all terrain" machines.
