    • A gearbox 10 comprises an input shaft 16 having a driving roller 24, an output shaft 34 with a driven roller 30 and a pair of variator discs 12 mounted for engagement with opposite sides of the driving and driven rollers 24, 30. Either or both of the input 16 and output shafts 34 are mounted for axial displacement along a radius of the variator discs 12.The axial displacement of the input and/or output shafts 16, 34 moves the point of contact between the driving 24 and/or driven 30 rollers to different radial positions relative to the variator discs 12. The gearbox 10 may have more than one input shaft 16, 18 and/or more than one output shaft 34, 38, and a plurality of input and/or output shafts can be grouped such that the shafts of each group are geared to an adjacent shaft of the group at a 1:-1 ratio.

    • A variable ratio gear assembly and transmission system. A rotor (10) carried by a piston and cylinder device (13, 15) engages a drive face (9) on a rotatable input shaft (3) and also engages a drive face (27) on a rotatable disc (28). Rotation of the shaft (3) imparts traction or fluid film drive to the rotor (10) which latter imparts traction or fluid film drive to the disc (28). Variation in the ratio of the gear is effected by actuation of the piston and cylinder device (13,15) to displace the rotor (10) over the drive faces (9) and (27) whilst maintaining engagement therewith. A further rotor (33) carried by a piston and cylinder device (36, 38) drivingly engages by traction or fluid film drive with opposed drive faces (32 and 43) respectively carried by the disc 28 and an output shaft (45). Displacement of the rotor (33) by actuation of the device (36, 38) varies or further varies the gear ratio.
      The drive face (9) is urged into engagement with the rotor (10) by a pin and slot device (7) which is responsive to the rotation of shaft (3). The piston and cylinder device (13, 15) (and possibly 36, 38) is pivotally mounted at (26) to the housing (1) so that it can be pivoted and urged into closer engagement with the drive face (27) upon axial displacement of the drive face (9) towards the face (27).
      Mounted in the drive face (9) is a freely rotatable rotor (50) having a non-driving region (49) which when engaged by the rotor (10) does not transmit drive from the shaft (3) to the rotor (10). Rods (25 and 42) permit manual adjustment of the piston and cylinder devices. The output shaft (45) may be displaceable axially to move its drive face (43) into or out of engagement with the rotor (33).
    • 可变比率齿轮组件和传动系统。 由活塞和缸体装置(13,15)承载的转子(10)与可旋转的输入轴(3)上的驱动面(9)接合并且还接合可旋转盘(28)上的驱动面(27)。 轴(3)的旋转将牵引或流体膜驱动施加到转子(10),该转子(10)将牵引或流体膜驱动施加到盘(28)。 通过致动活塞和缸体装置(13,15)以使转子(10)在驱动面(9)和(27)上移动同时保持与其接合的同时实现齿轮比的变化。 由活塞和缸体装置(36,38)承载的另一转子(33)通过牵引或流体膜驱动与分别由盘28和输出轴(45)承载的相对的驱动面(32和43)驱动地接合。 通过致动装置(36,38)使转子(33)的位移改变或进一步改变传动比。 通过响应轴(3)的旋转的销和槽装置(7)促使驱动面(9)与转子(10)接合。 活塞和缸体装置(13,15)(并且可能地36,38)在(26)处可枢转地安装到壳体(1),使得其可枢转并且在轴向上被推动而与驱动面(27) 驱动面(9)朝向面(27)的位移。 安装在驱动面(9)上的是一个具有非驱动区域(49)的可自由旋转的转子(50),该驱动区域在与转子(10)接合时不会将驱动从轴(3)传递到转子(10) 。 杆(25和42)允许手动调整活塞和缸体装置。 输出轴(45)可以轴向移动以将其驱动面(43)移动到与转子(33)接合或脱离接合。
