摘要： A continuously-variable ratio transmission comprising a ratio-varying unit ('variator'), and an epicyclic unit having three outputs arranged concentrically. Two of those outputs are connected respectively in fixed ratio to opposite ends of the variator, so that as the variator ratio changes, the speed of one of these outputs always rises and that of the other falls. These two outputs are also connected by appropriate gearing and clutches to the CVT output shaft. Successive regimes of operation, so extending the overall ratio range of the CVT, are obtained by alternatively connecting each of the two epicyclic outputs to the CVT output. Ratios and other parameters are chosen so that regime changes are synchronous.

摘要： A variator for a continously-variable-ratio transmission (CVT) of the half-toroidal traction roller type in which a ratio change results when a roller (6) exercices a first freedom of movement by rotating about a first or precession axis (10). In addition, the roller mounting has a further freedom of movement about a second or tilt axis (16). The precession axis (10) is inclined at an angle ('the castor angle') to a plane lying normal to the axis of the races, and each equilibrium value of the ratio angle correlates with a unique angular orientation of the roller (6) about the tilt axis (16).

摘要： A continuously-variable-ratio transmission with coaxial input (from 6) and output (17), capable of operating in a least two regimes, and comprising in succession a variator (2) of the toroidal-race rolling-traction type, and gearing including both a speed-reducing unit (10) and an epicyclic mixing gear unit (15) in which the components of the mixing gear unit are locked-up in at least one of the regimes, and in which the speed-reducing unit (10) effects its speed-reduction without reversal of the direction of rotation between its input (1) and output (from 26). The operating axis (5) of the variator (2) may either coincide with the coaxial input and output of the transmission (Figure 2), or be parallel to but displaced from it (Figure 3). In addition to a brake (13) and clutch (20), operable to engage first and second regimes, a further clutch (48) operable to engage a third regime is shown.

摘要： Une transmission à variation continue avec une entrée (de 6) et une sortie (17) coaxiales, pouvant fonctionner à au moins deux régimes, et comprenant successivement un variateur (2) du type à roulement-traction et à voie toroïdale, et des engrenages comprenant à la fois un démultiplicateur (10) et un train planétaire mixte (15) dans lequel les éléments du train planétaire sont bloqués dans au moins l'un des régimes, et dans lequel le démultiplicateur (10) effectue la réduction de vitesse sans inverser le sens de rotation entre son entrée (1) et sa sortie (de 26). L'axe de fonctionnement (5) du variateur (2) peut soit coïncider avec l'entrée et la sortie coaxiales de la transmission (fig. 2), soit être parallèle mais décalé par rapport à celles-ci (fig. 3). En plus d'un frein (13) et d'un embrayage (20) fonctionnant de manière à passer en premier et en second régimes, un embrayage additionnel (48) permettant de passer en un troisième régime est décrit.
