Title (EN) VARIABLE GEARBOX
(FR) TRANSMISSION VARIABLE
(DE) VERSTELLBARES GETRIEBE
Abstract:
(EN) The invention relates to a variable gearbox (1), with an input shaft (21) and an output shaft (20), a pair of friction discs (30, 31), which face each other with the concave surfaces (37) thereof, whereby the input shaft (21) and the output shaft (20) are, at least radially, each connected to one of the friction discs (30, 31) respectively and a friction wheel means device (40) is adjustably arranged between the friction discs (30, 31) and provides a force path between the friction discs, whereby the friction discs (30, 31) are arranged to rotate about the respective mid-axes (50, 51) thereof.
(FR) L'invention concerne une transmission variable (1) constituée d'un arbre menant (21) et d'un arbre mené (20), d'une paire de coques de friction (30, 31), dont les surfaces concaves (37) se font face, l'arbre menant (21) et l'arbre mené (20) étant couplés au moins radialement à une coque de friction respective (30, 31), et d'un dispositif central (40) à roues de friction, placé entre les coques de friction (30, 31) de façon ajustable et garantissant un flux de force entre ces coques de friction, lesquelles coques (30, 31) sont agencées de façon à pouvoir tourner autour de leur axe central respectif (50, 51).
(DE) Verstellbares Getriebe (1), mit einer Antriebswelle (21) und einer Abtriebswelle (20), einem Paar Reibschalen (30, 31), die sich mit ihren konkaven Flächen (37) einander gegenüberliegen, wobei die Antriebswelle (21) und die Abtriebswelle (20) mit jeweils einer der Reibschalen (30, 31) zumindest radial gekoppelt sind, und mit einer Reibradmitteleinrichtung (40), die zwischen den Reibschalen (30, 31) verstellbar angeordnet ist und die einen Kraftfluss zwischen den Reibschalen gewährleistet, wobei die Reibschalen (30, 31) um ihre jeweilige Mittelachse (50, 51) drehbar angeordnet sind.
