摘要： An add-on overdrive unit for location on an extended output shaft of an automatic transmission. The unit includes a planetary gear set connected by means of its annulus gear to an outer face of a one-way clutch. The one-way clutch inner face is concentrically interconnected to the transmission output shaft. An hydraulic piston operates a first direct-drive clutch pack and a second overdrive clutch pack. The piston is normally biased to its non-pressurized failsafe direct drive position by a compression coil spring. As a result the direct drive clutch pack is engaged causing the planetary sun gear to be locked to the annulus gear providing a one-to-one direct drive speed ratio to the overdrive output shaft via the engaged one-way clutch outer race. Upon the piston being pressurized the overdrive clutch pack is engaged and the direct drive clutch pack is released grounding the sun gear to the overdrive case. In its overdrive mode torque is transferred from the transmission output shaft via a planet carrier ring, the planet gears and the annulus gears to the outer face of the disengaged one-way clutch. Thus, drive torque is transferred through the direct-drive clutch pack only in the reverse mode of the transmission.

摘要翻译： 一个附加的过驱动单元，用于定位在自动变速器的扩展输出轴上。 该单元包括通过其环形齿轮连接到单向离合器的外表面的行星齿轮组。 单向离合器内表面与变速器输出轴同心连接。 液压活塞操作第一直接驱动离合器组件和第二超速离合器组件。 活塞通常被压缩螺旋弹簧偏压到其非加压故障安全直接驱动位置。 结果，直接驱动离合器组件被接合，使得行星太阳齿轮被锁定到环形齿轮，通过接合的单向离合器外圈与过驱动输出轴提供一对一的直接驱动速度比。 当活塞被加压时，超速离合器组件被接合并且直接驱动离合器组件被释放将太阳齿轮接地到超速传动壳体。 在其过驱动模式中，扭矩通过行星架环，行星齿轮和环形齿轮从变速器输出轴传递到分离的单向离合器的外表面。 因此，仅在变速器的反向模式下，驱动转矩通过直接驱动离合器组件传递。

摘要： An arrangement for dampening a transmission synchronizer. A plurality of T-shaped shoes are disclosed for assembly on the jaw toothed shoulder of the synchronizer main gear. The shoulder has a plurality of chordal flats with a radial bore formed therein. Each T-shaped shoe is molded of resilient material and includes a cross head portion and a stem for reception in its associated radial bore. The synchronizer stop ring has selected individual ones of its internal teeth omitted creating slots defined by the omitted tooth together with the adjacent root spaces. The cross head is sized to snugly contact the opposed flanks of the adjacent stop ring teeth. By urging the stop ring internal teeth into a neutral centered position with the gear teeth the invention obviates stop ring rattle by eliminating play between the stop ring and the main gear.

摘要翻译： 用于抑制传动同步器的装置。 公开了用于组装在同步器主齿轮的爪齿肩上的多个T形鞋。 肩部具有多个形成有径向孔的弦平面。 每个T形鞋由弹性材料模制而成，并包括一个十字头部分和一个用于在其相关的径向孔中接收的杆。 同步器止动环已经选择了其内部的单个齿，省略了由省略的齿与相邻的根部空间一起定义的槽。 十字头的尺寸适于紧贴相邻止动环齿的相对侧面。 通过推动止动环内齿与齿轮齿处于中立的中心位置，本发明通过消除止动环和主齿轮之间的游隙来消除止动环拨浪鼓。
