摘要： The invention concerns a variator (2) having a pair of semi-toroidally recessed races (11, 12) mounted to a housing (6) for rotation about a common variator axis. A roller (14) is mounted between the races to transfer drive between them at a variable drive ratio. A sun gear (25) is mounted between the races, as is a ring (gear 26). The ring gear is radially outboard of the sun gear. Mounted between the sun and ring and meshing with both is a carrier gear (33) upon which the roller is mounted in a manner which enables it both to spin about its own axis, when turned by the races, and also to tilt relative to the races to vary the drive ratio. A control pinion (27) is also arranged between the sun and ring gears meshing with both. The control pinion is able to rotate about its own axis freely, but the pinion axis is fixed with respect to the housing.

摘要： The invention concerns an electronic controller for a continuously variable transmission of the type having a variator (10) with a rotary variator input (17) coupled to a first variator race (14a) and a rotary variator output (29) coupled to a second variator race (16a). At least one roller (20) runs upon the said races to transfer drive from one to the other. The roller is movable to steplessly vary the vaiϊator ratio. The variator further comprises at least one hydraulic actuator (36), (38) which acts upon the roller and through which net torque acting on the variator races is referred via the roller to the variator' s casing. A hydraulic arrangement is provided for applying to the actuator at least one hydraulic control pressure which determines force applied' by the actuator and thus determines the reaction torque. The varialtor is coupled between a rotary transmission input (17) and a rotary transmission output (714) such that the transmission ratio is a function of the variator ratio. The electronic controller is adapted to cany out the following steps in a loop: measure a speed ratio of the continuously variable transmission; compare the measured speed ratio with a target speed ratio; determine a transmission output torque request on the basis of the said comparison; convert the output torque request to a control pressure request, taking account of the speed ratio; differentiate the control pressure request with respect to lime to obtain a compensation value and apply the compensation value to the control pressure request; and output the resulting compensated control pressure reqxiest to the hydraulic valve arrangement.

摘要： An arrangement is disclosed for providing an "end-stop" function for a variator in a continuously variable transmission. The variator (8) needs some arrangement for preventing its own drive ratio from going beyond a ratio limit. In accordance with the present invention, this is provided by means of a one-way clutch (22 or 24). The one-way clutch is coupled to both the variators input and its output, and is arranged to engage (lock up) when the variator reaches its ratio limit, so that the variator is prevented from going beyond the limits. The invention is particularly suited to use with transmissions which provide two regimes and a synchronous change between them.
摘要翻译：公开了一种用于为无级变速器中的变换器提供“终止”功能的装置。变速器（8）需要一些布置来防止其自身的驱动比超过比率限制。根据本发明，这是通过单向离合器（22或24）来提供的。单向离合器耦合到变换器输入端和输出端，并且当变频器达到其比例极限时被布置成接合（锁定），从而防止变速器超出极限。本发明特别适用于提供两种方案的传输和它们之间的同步变化。

摘要： In a continuously variable transmission ("CVT") using a toroidal-race continuously variable ratio device and a planetary gear mechanism, the rotation of the input shaft (12) is directly transmitted to the carrier C of the planetary gear mechanism (6 1 ), and rotation resulting from gearing and reversal by the variator (5) is transmitted to the sun gear (S1). When the low clutch L is engaged, the rotation of the ring gear (R3) is transmitted via the reversing gear mechanism (7 1 ) to the output shaft (13), and when the high clutch H is engaged, the rotation of the sun gear (S2) is transmitted to the output shaft (13).

摘要： A continuously variable transmission comprises coaxial system input and output shafts (16, 20), a continuously variable ratio transmission unit (variator) (V) connected coaxially to the system input shaft (16) and having a coaxial variator output shaft (18) and a mixing planetary gear train (G1). The mixing planetary gear train has an input sun gear (S 1) drivably connected to the variator output shaft (18), a planet carrier (C 1) drivably connected to the system input shaft (16), a first planet gear (P 1) mounted on the planet carrier (C 1) and drivingly engaged with the input sun gear (S 1), a second planet gear (P2) mounted on the planet carrier (C 1) and arranged to rotate with the first planet gear (P 1) and drivingly engaged with an output sun gear (S2) connected to an output shaft (20). The ratio R1 (the number of teeth on the input sun gear ÷ by the number of teeth on the first planet gear) is set to be greater than R2 (the number of teeth on the output sun gear ÷ by the number of teeth on the second planet gear). This ensures that the variator always transmits less than 100% of the engine power, which allows the variator to be made more compact.

摘要： The present invention is concerned with the formation of rollers in a rollingtraction toroidal-race type of continuously variable ratio transmission device ("variator"). Specifically, it concerns variators of the "full-toridal" type in which the variator rollers (48) are permitted to adopt a position in which their centres are close to -or even coincident with - the center line of a toroidal cavity defined by races (30, 32, 42). It has been recognised that the roller centres do not, in such a variator, lie precisely upon the centre line of the variator cavities. Consequently in order to optimise roller performance there is provided, in accordance with the present invention, a roller (70) having an outer perimeter which, viewed in a sectional plane containing the roller axis, has a convex profile which is not symmetrical about any plane perpendicular to the roller axis.
