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 concerns a continuously variable transmission having a transmission input (60) and a transmission output (114). The transmission has a variator (56). This is a device which transmits drive at steplessly variable ratio. It further comprises an epicyclic gear arrangement (58) incorporating a clutch arrangement (152). The epicyclic gear arrangement has three rotary members. One of these is coupled to a planet carrier (86) having at least one planet gear (94). Another of the rotary members is coupled to a main gear (90) meshing with the planet gear. The clutching arrangement serves to couple the remaining rotary member to either of first and second alternative gears (96, 98), both of which mesh with the planet gear and which rotate at different speeds. One of the aforesaid rotary members is coupled to the transmission input at a fixed drive ratio. One of them is coupled to the variator output. The last of the rotary members is coupled to the transmission output. By means of the clutching arrangement the transmission can be changed between first and second ratio ranges.

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 supply outlet which communicates with the hydraulic 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 pressure at the hydraulic actuator which is greater 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.
摘要翻译：本发明涉及一种用于控制无级变速器的装置。变速器包括具有可移动转矩传递部分（辊18）的变换器（10），其位置对应于变换器驱动比。液压致动器（28）布置成在扭矩传递部件上施加可调节的力。变速器还包括一个流量控制装置，其被布置成作为控制输入（a）接收扭矩传递部件的当前位置，以及（b）所需的位置。所要求的位置可以例如由驾驶员输入确定。流量控制装置适于通过与液压致动器连通的供应出口提供根据两个控制输入之间的误差调制的流体流。流体的流动随着误差的增加而增加。释放通道（110）从所述出口引导到压力沉降器并且被收缩，使得流体通过其的流体导致液压致动器的压力大于水槽的压力，其量对应于流量通过救济通道。结果是传动的控制方式，具有扭矩和比率控制的一些优点。

摘要： A multi-regime continuously variable ratio transmission has a transmission input shaft, a transmission output shaft, and a ratio varying unit having a rotating input and a rotating output, the rotational axes of the input and the output being coaxial. A shunt having first and second epicyclic gear sets is connected across the ratio varying unit. One gear set has an input driven by the input shaft and an input driven by one side of the ratio varying unit and the other gear set has an input from the first gear set and an input from one side of the ratio varying unit. The gear sets rotate about a common axis and are offset with respect to, and parallel to, the rotational axes of the input and output of the ratio varying unit. A clutch is operable to selectively connect the output of the second gear set to the output shaft.
