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 ("CVT"), for instance of the toroidal-race rolling-traction type, capable of geared neutral and of operating in at least two regimes and including a ratio-varying component ("variator") (4), a power-recirculating epicyclic (E), a final drive shaft (1) connectable with the variator (4) by way of one of two alternative driven shafts (A, B) and an input epicyclic (e) the input (35) of which is connectable to a prime mover (3) and the two outputs (36, 40) of which are connected to the two alternative driven shafts (A, B) respectively. One of the regimes includes a "geared neutral" condition, and the power-recirculating epicyclic (E) is associated with clutches (44, 46) whereby power is recirculated through it in that regime. In the remaining one or more regimes no power is recirculated within that epicyclic (E), but drive reaches the CVT output (1) by way of appropriate clutches (44, 46; 48, 47; 49; 45) and whichever of the two driven shafts (A, B) will rise in speed as that regime proceeds.

摘要： A vehicle driveline including a control system subject to operator demand, and a continuously-variable-ratio transmission (CVT) including a variator of torque-controlled type, in which the control system includes a performance "map" of optimum relationships between engine torque and speed over a range of values of those two quantities, and in which the control system regulates both the energy input to an engine and also the reaction torque at the variator so as to seek a state in which the mapped optimum relationship between engine torque and speed is maintained. The variator may be of the toroidal-race rolling-traction type, reaction torque within it being regulated by controlling the operating force applied to the variator rollers. The control system may act so as to compute the variator reaction torque with relation to two alternative calculations based on the transmission input and output torques respectively, and may choose for operation at any given time the calculation yielding the lesser value of that variator reaction torque.

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 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 invention concerns an arrangement for control of a continuously variable transmission. The transmission includes a variator (10) having a movable torque transfer part (rollers 18) whose position corresponds to a variator drive ratio. A hydraulic actuator (28) is arranged to exert an adjustable force on the torque transfer part. The transmission further comprises a flow control arrangement which is arranged to receive as control inputs (a) the current position of the torque transfer part and (b) a demanded position for it. The demanded position may for example be determined by driver input. The flow control arrangement is adapted to supply through a s upply o utlet w hich c omniunicates w ith t he h ydraulic actuator a flow of fluid which is modulated in accordance with an error between the two control inputs. The flow of fluid increases with increasing error. A relief passage (110) leads from the said outlet to a pressure sink and is constricted so that fluid flow through it results in a p ressure at the hydraulic a ctuator which is g reater than that of the sink by an amount which corresponds to the rate of flow through the relief passage. The result is a mode of control of the transmission which possesses some of the advantages of both torque and ratio control.

摘要： The invention concerns a simple mechanical arrangement for controlling a multi- regime continuously variable transmission. The transmission in question comprises a variator (10) and a gearing arrangement including a low regime clutch (C L ) and a high regime clutch (C H ). Engaging the low regime clutch places the transmission in the low regime. Engaging the high regime clutch places it in the high regime. The control system comprises a control part (such as a lever) which is movable by the user along a control path from a low ratio end to a high ratio end. The position of the control part dictates variator ratio and transmission ratio. The system further incorporates a low regime clutch control device which engages the low regime clutch when the control part is between the low ratio end of its path and a low clutch transition point, and which releases the low regime clutch when the control part is between the low clutch transition point and the high ratio end of its path. It additionally incorporates a high regime clutch control which releases the high regime clutch when the control part is between the low ratio end of its path and a high clutch transition point, and which engages the high regime clutch when the control part is between the high clutch transition point and the high ratio end of its path. In this way, a mechanical arrangement can be provided which manages both transmission ratio and the clutch changes required upon regime change.

摘要： The invention relates to an arrangement for controlling a variator in a continuously variable transmission such as a vehicle transmission. The arrangement comprises a user operable ratio control part such as a lever 50 and a device for operatively coupling the ratio control part to a movable torque transfer part of the variator such as its rollers 18. The coupling device is, in the particular embodiment described, a hydro-mechanical arrangement. By moving the user operable ratio control part 50, the user exercises control over the variator ratio. In accordance with the invention the arrangement further comprises a torque release device such as a valve 60 which is operable by the user to decouple the ratio control part from the movable torque transfer part. By doing so, the torque release device offers functionality which is in some ways analogous to that of a clutch in a conventional stepped ratio vehicle transmission.
