摘要： A continuously-variable-ratio transmission (CVT) of the toroidal-race rolling-traction type, capable of operating in 'low' and 'high' regimes with synchronous change between those regimes, and including a variator (3) - that is to say a ratio-varying component - and an associated gearing set (2) of which the components are capable of being set in different combinations for the high and low regimes, in which the output of the gearing is connectable to the output (1) of the CVT as a whole, and the gearing has first (25) and second (29) inputs connected with the variator output (19) and engine output (5) respectively, and in which in low regime the gearing is set to recirculate power and so deliver to its output a power equal to the difference between its two input powers, whereas in high regime it is set so as to split the power flow and to deliver to its output a power representing the sum of the powers at its two inputs.

摘要： A continuously-variable ratio transmission of the toroidal-race rolling-traction type, especially in and for an automobile vehicle. The ratio transmitted by the rollers (10) is determined by the position of a double-ended piston (15), the ends of which move in cylinders (17, 16) respectively connected to further cylinders (31, 36) the pistons (33, 38) of which are movable by the opposite limbs of a rocking pedal (42) controlled by the operator. Rocking of the pedal in one direction depresses one such piston (e.g. 33) and releases the other, thereby moving the double-ended piston (15) in one direction and so inducing ratio change in one sense, while rocking the pedal in the opposite direction has the opposite effect. The cylinders (31, 36) of the pedal-controlled pistons may be mounted in a fluid reservoir (34), and formed with ports through which the fluid lines are topped-up from the reservoir each time the pistons (33, 38) rise close to the tops of their strokes.

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： A variator for a transmission of the toroidal-race rolling-traction type in which a multiplicity of input discs (1-4) and output discs (11-13) are arranged alternately in coaxial sequence, all disc except the first (1) and last (4) in the sequence being formed with races (9, 10) on both of their faces. Drive is transmitted from the output discs to one (35) or several (45-47) output shafts, the output shaft or shafts preferably lying parallel to but displaced from the common axis (8) of the discs. Alternative ways of inter-relating the orientation of the torque-transmitting rollers (20), to produce single or multiple outputs of the transmission, are described. The invention offers the prospect of a variator of higher-than-normal traction-transmitting capacity but using discs of only normal size.

摘要： A driveline for a wheeled vehicle in which two laterally-displaced driving wheels (37, 38) are driven by the output (33, 36) of a transmission of continuously-variable ratio. The transmission is capable of a ''geared neutral'' condition, and is driven by way of a slipless connection (5, 6, 7; 70-73) from the engine (2). The engine output axis (3), the engine/transmission connection and the variator output axis (15) are arranged in a ''U''-shaped formation. Such an arrangement promotes a compact and well-balanced installation in which the vehicle centreline (1) may roughly bisect the engine, and the wheel half-shafts (43, 44) can be nearly equal in length. Alternative embodiments are described in which the output axis of the variator coincides with the final drive axis (Fig. 3), or is parallel to but displaced from it (Fig. 1).

摘要： Système de commande de rouleau pour transmission de rapport à réglage continu de type à traction roulante et voie toroïdale, dans lequel un ensemble rouleau comprend un rouleau (1) monté sur un chariot, et dont le mécanisme de commande (10) entre en contact avec le chariot et lui applique une certaine force de commande prédéterminée, de manière à commander la façon dont le rouleau transmet le couple et le rapport entre les deux disques avec lesquels il est en contact, et dans lequel l'ensemble rouleau est maintenu en place par seulement trois contacts avec les composants adjacents, à savoir les deux contacts disque/rouleau et le contact avec le mécanisme de commande. Le centre du rouleau (6) peut se déplacer le long de l'axe du rouleau (5) par rapport au chariot, le chariot et le mécanisme de commande étant reliés par un joint articulé (7) permettant une liberté de mouvement d'un degré seulement. Le mécanisme de commande préférentiel est de type à piston (11, 12) et cylindre (13, 14). L'axe (8) de l'articulation peut soit se trouver entre le mécanisme de commande et le rouleau, soit passer à travers le mécanisme de commande lui-même (par ex. 40, fig. 4).

摘要： A roller control system for a continuously-variable-ratio transmission of the toroidal race, rolling traction type, in which rollers (60) of variable orientation transmit traction between a part-toroidal race (85) formed on an input disc (61) and a similar race (87) formed on a coaxial output disc (62). Each roller is mounted to rotate about a fixed centre (66) and a fixed axis (58) within a rigid carriage (67), one end of which contacts operating mechanism reciprocable over a predetermined stroke of operating movement and operable to apply a control force to the carriage. The assembly of roller and carriage is located by only three contacts with adjacent structure, namely the two disc/roller contacts (86, 88) and the contact (82) with the operating mechanism. These three contacts suffice to cause the roller constantly to seek a ratio angle at which the instantaneous value of the control force is balanced by the instantaneous value of the traction forces to which the roller assembly is subjected due to the contact between the roller and the two discs, and at which the transmission is therefore in equilibrium.

摘要： Est décrit un disque rotatif (1, 3) pourvu d'une cage coaxiale partiellement toroïdale (26, 27, figure 5) s'utilisant comme disque d'entrée ou de sortie du variateur pour une transmission du type roulement-traction à cage toroïdale, notamment du genre entièrement toroïdale, dans laquelle le rayon du tore (rd) de la cage, c'est-à-dire le rayon de courbure de la cage mesuré en un point choisi de la cage et dans un plan comprenant l'axe du disque, diminue proportionnellement à la distance séparant ce point de l'axe du disque (5). Cette diminution du rayon du tore peut être soit continue ou discontinue.

摘要： Ensemble de transmission pour véhicules à roues, dans lequel deux roues motrices à déplacement latéral (37, 38) sont mues par la sortie (33, 36) d'une transmission à rapport variable en continu. Ladite transmission peut être mise en condition ''d'engrenage neutre'' et est mue par le biais d'une connexion sans glissement (5, 6, 7; 70-73) provenant du moteur (2). L'axe de sortie du moteur (3), la connexion moteur/transmission et l'axe de sortie du variateur (15) sont disposés en U. Une telle disposition permet d'obtenir un ensemble compact et équilibré, dans lequel l'axe central du véhicule (1) bissecte environ le moteur, tandis que les demi-arbres des roues (43, 44) sont presque de la même longueur. On décrit également d'autres modes de réalisation, dans lesquels l'axe de sortie du variateur coïncide avec l'axe moteur final (Fig. 3), ou est parallèle mais décalé par rapport à celui-ci (Fig. 1).
