Abstract

An inversely symmetrical rear wheel mobility system which is mounted on an endless screw enabling adjustment of the ground clearance of a motor bike with three wheels which can be inclined at an angle of more than 45 degrees.

Description

TITEE DE L'INVENTION:TITLE OF THE INVENTION:
Système de mobilité des roues arrières pour moto à 3 roues inclinable à plus de 45 degrés.Rear wheel mobility system for 3-wheel motorcycle tilting more than 45 degrees.
DESCRIPTION: 1/ La présente invention concerne le domaine de la moto àDESCRIPTION: 1 / The present invention relates to the field of motorcycles
3 roues (dont 2 à l'arrière) qui s'incline dans les virages sans perte d'adhérence des trois roues. 2/ L'état de la technique antérieure est la moto traditionelle à 2 roues limitée dans son adhérence, freinage, motricité et confort.3 wheels (including 2 at the rear) which tilts when cornering without losing grip on the three wheels. 2 / The state of the prior art is the traditional 2-wheeled motorcycle limited in its grip, braking, traction and comfort.
Le fait d'avoir 2 roues à l'arrière s 'inclinant dans les virages en même temps que le reste de la moto a.ugmente considérablement les capacités de la moto. Meilleure adhérence, motricité, freinage (1 frein par roue) et confort (4 amortisseurs à l'arrière). Le plus on pourra concevoir des motos plus grosses et plus lourdes sans l'angoisse de mal les tenir à l'arrêt ou à basse vitesse parce que la mo- to se maintiend en équilibre seule du fait de ses trois points de contact avec le sol.Having 2 wheels at the rear that tilts around corners at the same time as the rest of the bike greatly increases the bike's capabilities. Better grip, traction, braking (1 brake per wheel) and comfort (4 shock absorbers at the rear). The more we can design larger and heavier motorcycles without the anxiety of keeping them stationary or at low speed because the motor will maintain its balance alone due to its three points of contact with the ground .
3/ le système est caractérisé par une barre horizontale (dit "balancier") et deux barres verticales terminées par des articulations permettants la rotation dans deux plans assurant ainsi la mobilité inversement symétrique des bras oscillants supportants les roues.3 / the system is characterized by a horizontal bar (known as a "pendulum") and two vertical bars terminated by articulations allowing rotation in two planes thus ensuring the inversely symmetrical mobility of the oscillating arms supporting the wheels.
Le système qui permet la mobilité des bras oscillants est monté sur une vis sans fin permettant ainsi de faire varier le point d'ancrage de l'ensemble et par conséquent de faire varier la garde au sol de la moto.The system which allows the mobility of the swinging arms is mounted on a worm screw thus making it possible to vary the anchor point of the assembly and consequently to vary the ground clearance of the motorcycle.
Les parties verticales de ce système peuvent être remplacées par des amortisseurs pour donner selon le cas d'avantage d'indépendance aux roues arrières. -s transmission secondaire ne présente pas de difficultés particulière à résoudre. Celle-ci pourra se faire par double cardan, double chaîne ou double courroie (1 par roue) distribuée par l'intermédiaire d'un différentiel ( à gliε- sèment ou non).The vertical parts of this system can be replaced by shock absorbers to give, as the case may be, more independence to the rear wheels. -s secondary transmission does not present any particular difficulties to be resolved. This can be done by double gimbal, double chain or double belt (1 per wheel) distributed by means of a differential (sliding or not).
/ - L'ensemble (1) pivote sur* l'axe (2) qui lui-même est monté sur* une vis sans fin./ - The assembly (1) pivots on * the axis (2) which itself is mounted on * an endless screw.
- (3) sont des articulations permettants la rotation dans les deux ulans.- (3) are joints allowing rotation in the two ulans.
- L'ensemble (1) est relié au bras oscillant (4) par une patte de liaison (5).- The assembly (1) is connected to the swinging arm (4) by a connecting lug (5).
- (β) peut être remplacée par un amortisseur. ΓŒNT IONS DESSIN- (β) can be replaced by a shock absorber. ΓŒNT IONS DRAWING
-L'ensemble (1) pivote sur l'axe (2) qui lui-même est monté sur une vis sans fin.-The assembly (1) pivots on the axis (2) which itself is mounted on an endless screw.
