摘要： A continuously-variable-ratio automotive transmission, typically of the toroidal-race rolling traction type, in which mechanism comprising a clutch, a brake and two epicyclic combinations--a reversing train and a mixing train--is interposed between the ratio-varying unit and the output of the transmission as a whole. By operation of the clutch and the brake the elements within the mechanism may be arranged in two different combinations whereby the transmission may operate in first and second "regimes", one or other of which will offer efficient transmission throughout the entire operating range of the source of the automotive power. The invention lies in a particular choice of the two different combinations resulting in reasonable containment of gear speeds, no requirement for power to be transmitted through the intermeshing gears of an epicyclic when the transmission is in its second (high gear) regime, and no interference between the final member of the transmission and any grounding that any items within it--for instance the planet carriers of the epicyclics--may require. The latter feature facilitates the use of a simple solid gear, rather than an annular one, as the final transmission member.
摘要翻译：通常为环形滚道牵引式的连续变速比的汽车变速器，其中包括离合器，制动器和两个周转组合（反转列车和混合列车）的机构插入在比率变化单元和整个传输的输出。通过离合器和制动器的操作，机构内的元件可以以两种不同的组合布置，由此变速器可以在第一和第二“制度”中操作，其中一个或另一个将在源的整个操作范围内提供有效的传动的汽车电源。本发明在于两种不同组合的特定选择，导致齿轮速度的合理控制，当变速器处于其第二（高档））状态时，不需要通过行星齿轮相互啮合的齿轮传递动力，并且无干扰在传输的最终成员之间和其中任何项目（例如行星架的行星架）可能需要的任何接地之间。后一个特征有助于使用简单的实心齿轮而不是环形齿轮作为最终的传动部件。

摘要： A continuously-variable ratio automotive transmission, especially of the toroidal race rolling-traction type, in which mechanism comprising a clutch, a brake and two epicyclics--a reversing train and a mixing train--is interposed between the ratio-varying unit and the output member of the transmission as a whole. By operation of the clutch and the brake the elements within the mechanism may be arranged in two different combinations whereby the transmission may operate in first and second "regimes", one or other of which will offer efficient transmission throughout the entire operating range of the source of automotive power. The invention lies in a particular choice of the two different combinations resulting firstly in a transmission notably short in axial length. Secondly in the feature that in the regime including the reverse and lower forward speeds of the output member, power is transmitted to it from the variator through the full gearing of the two epicyclic trains, the planet carrier of the reversing train then being locked by a connected braking arm which lies parallel to the transmission axis and reaches its point of anchorage by passing through the middle of an annular gear which constitutes the output member.
摘要翻译：一种无级变速比的汽车变速器，特别是环形滚道牵引式的变速比，其中包括离合器，制动器和两个行星齿轮 - 换向列车和混合列车的机构被插入在比率变化单元和输出整个传输成员。通过离合器和制动器的操作，机构内的元件可以以两种不同的组合布置，由此变速器可以在第一和第二“制度”中操作，其中一个或另一个将在源的整个操作范围内提供有效的传动的汽车电源。本发明在于两种不同组合的特定选择，其首先在轴向长度上显着地短。其次，在包括输出构件的反向和低速前进速度的制度中，功率通过两个行星列车的完全传动从变速器传递给它，然后由反向列车的行星架被一个连接的制动臂平行于变速器轴线并通过穿过构成输出构件的环形齿轮的中间而到达其固定点。

摘要： A device for damping both radial and axial motions of one mechanical part relative to another. The two parts may, for instance, be the fixed structure of a toroidal race variable-ratio transmission unit and the control sleeve of the unit. A flexible fluid-filled envelope fills the annular gap between one of these parts and the other, and the interior of the envelope is in the form of two volumes, one at each axial end and joined by a constriction in the middle. Relative radial motion between the two parts is damped by distortion of the envelope and consequent rotary movement of the fluid within. Relative axial motion is damped because the relative sizes of the two volumes change, and fluid moves from one volume to the other through the constriction.
摘要翻译：一种用于阻止一个机械部件相对于另一机械部件的径向和轴向运动的装置。这两个部件可以是例如环形变速比传动单元和单元的控制套筒的固定结构。柔性流体填充的封套填充这些部件之一和另一个之间的环形间隙，并且外壳的内部是两个体积的形式，一个在每个轴向端部处，并且在中间由一个收缩部连接。两个部件之间的相对径向运动由于包络线的变形和内部流体的旋转运动而衰减。相对轴向运动被阻尼，因为两个体积的相对尺寸发生变化，并且流体通过收缩从一个体积移动到另一个体积。
