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： A hydraulic control valve for a continuously-variable-ratio transmission (CVT), particularly one of the toroidal race rolling traction type. The transmission includes hydraulically-operated clutches (25,26) whose capacity to transmit torque varies with the operating pressure supplied to them. The transmitted ratio is related to the position of a hydraulic ram (35), which when it overshoots its normal stroke creates a pressure rise upstream of it in the circuit. This pressure rise first resists further overshoot, and then causes a reduction in the clutch operating pressure. Ram position is controlled by valve means (56,57) which are located downstream of the ram, and which are themselves sensitive (via 58) to feedback from upstream circuit pressure: when that pressure rises, the valve means open so as to depress the downstream circuit pressure by which the clutches are operated (via 68). In the illustrated embodiment of the invention a double-acting ram is shown, controlled by a circuit comprising two parallel hydraulic lines (42,54: 43,55) associated respectively with the opposite ends (36,37) of the ram, each line being controlled by a separate downstream control valve. The pressure feedback to the control valves and the operating pressure for the clutches are taken from cross-connections (48,60) between the two lines, so that each such pressure always has the higher of the values existing in the two lines at each end of the cross-connection.

摘要： The present invention concerns a transmission arrangement particularly suited for use with a motor vehicle which has left and right hand transmissions 200 L , 200 R . A left hand variator 204 L , 404 L comprises a left hand input race 222 L driveable from a transmission input 220, 520, 620 and a left hand output race 226 L , 426 L , 626 L . A set of left hand variator rollers 224 L is arranged to transmit drive between the left hand input race and the left hand output race. The left hand variator rollers are moveable to permit continuous change in the ratio of rotary speed of the left hand input are to that of the left hand output race. A left hand epicyclic unit 210 L has two left hand epicyclic inputs 226 L , 234 driveable respectively along with the left hand input race and the left hand output race, and a left hand epicyclic out 234 which is arranged to drive a left hand transmission output 240 L , 440 L , 640 L . A right hand transmission is formed in similar manner. In accordance with an aspect of the invention, the left and right hand epicyclic units are both frictional devices in which epicyclic planets 234 are formed as rollers, and more specifically as balls, which run upon annular surfaces of a pair of epicyclic elements and which are carried in planet carriers. The rollers of the left hand variator are moveable independently of the rollers of the right hand variator, so that the speeds of the left and right hand transmission outputs are independently variable.

摘要： A method is disclosed for obtaining a signal representing motor vehicle acceleration. The method involves obtaining a high pass filtered vehicle acceleration signal and a low pass filtered vehicle acceleration signal. One of these signals (preferably the high pass filtered signal) is obtained based upon the net driving force applied to the vehicle, which can be used to obtain an estimate of acceleration by means of an adoptive vehicle model (28). The other signal is obtained by measurement, for example by differentiating a measured vehicle speed signal with respect to time. Adding the two filtered signals together gives a vehicle acceleration signal of potentially good quality.

摘要： In a continuously-variable-ratio-device ("variator") of the type having races (12, 14, 26, 102) between which drive is transferred by rollers (28) which are movable in accordance with changes of variator ratio, it is necessary to apply a traction load urging the rollers and races into engagement. Each rollers is also subject to a transverse reaction force by a hydraulic reaction roller actuator (32) receiving a i controlled reaction pressure. It is desirable to create a relationship between traction and reaction force, and also to provide for adjustment of this relationship. In the present invention this is achieved hydraulically. A traction pressure related to the reaction pressure is applied to an actuator (72, 100) which creates the traction load. The hydraulics also include a working chaniber (C2, C4, CH1, CH2, CH3) which is selectively connectable to and disconnectable from either (or both) of (i) the reaction pressure and (ii) the traction pressure, the traction force being dependent upon pressure in the working chamber.
