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 (CL) and a high regime clutch (CH). 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 is concerned with a continuously variable transmission incorporating a variator of the type having at least two co-axial races (D1-D4) between which drive is transferred at a continuously variable variator ratio. The variator races are mounted for rotation about a variator shaft (16). The transmission has a layshaft (18) which is laterally separated from the variator shaft. It has two epicyclic gears. A splitter epicyclic (14) has an input member driven from the transmission input (10) and two output members arranged respectively to drive the layshaft and the variator shaft. A recirculater epicyclic has first and second input members for coupling respectively to the variator shaft and to the layshaft and a recirculater output member. An arrangement of clutches is provided for selectively engaging any of at least three regimes. In one regime the recirculater output member drives the transmission output. In another the layshaft drives the transmission output. In a third, the variator shaft drives the transmission output. The arrangement of the components is such that the variator shaft is co-axial with the transmission output, the recirculater epicyclic, a first coupling, between the recirculater output member and the transmission output, which serves to drive the transmission output in the first regime, and a second coupling, between the variator shaft and the transmission output, which serves to drive the transmission output in the third above-mentioned regime.

摘要： The invention is concerned with control of a continuously variable vehicle transmission. The transmission in question is to have a variator (10) which is coupled between a rotary transmission input (32) and a rotary transmission output (46), to provide continuous variation in a transmission drive ratio, via a launch device such as a clutch (62; 68). The variator and the launch device are constructed and arranged to exert a required torque, defined by an input signal. In accordance with the invention, the same control signal is used to control both the variator torque and the torque capacity of the launch device. In such an arrangement, vehicle launch (i.e. moving away from rest) can be controlled in a straightforward manner by progressively raising the relevant control signal, preferably a hydraulic pressure signal. Further independent claims are including for applying traction load to races (20, 22) of the variator and for a method setting torque of the launch device (62; 68) higher than torque of the variator (10).
摘要翻译：本发明涉及无级变速车辆变速器的控制。所讨论的变速器是具有连接在旋转变速器输入（32）和旋转变速器输出（46）之间的变速器（10），以通过发射装置（例如离合器）提供传动驱动比的连续变化（62; 68）。变速器和发射装置被构造和布置成施加由输入信号限定的所需扭矩。根据本发明，使用相同的控制信号来控制发射装置的变换器扭矩和扭矩容量。在这种布置中，可以通过逐渐提高相关的控制信号，优选液压信号，以直接的方式来控制车辆发射（即，远离静止状态）。进一步的独立权利要求包括用于将牵引载荷施加到变速器的座圈（20,22）上，以及用于将发动装置（62; 68）的方法设定转矩高于变换器（10）的扭矩。
