    Abstract: A transmission includes multiple lay shaft branches driven by gearing on an input shaft. Each lay shaft branch engages a common output gear and includes a clutch. The input shaft is journalled within a hydraulically adjustable bearing which controls input shaft displacement. When friction clutches are employed in the branches, maximum input shaft displacement is provided after clutch engagement to compensate for different frictional forces in each clutch. If positive locking clutches are employed in the branches, maximum input shaft displacement is permitted prior to engagement of the second clutch to provide synchronism between the primary and secondary components of the second clutch. In one embodiment, the adjustable bearing comprises a thrust bearing which permits axial movement of the input shaft while the input shaft gearing comprises helical ring gears having opposite slope. An alternate embodiment encompasses a single drive gear on the input shaft with the bearing being adjustable to permit transverse displacement of the input shaft axis for movement into planes parallel to a common plane of the branch axes.

    Abstract translation: 变速器包括由输入轴上的齿轮驱动的多个副轴分支。 每个副轴分支接合公共输出齿轮并且包括离合器。 输入轴安装在控制输入轴位移的液压可调轴承内。 当在分支中使用摩擦离合器时，在离合器接合之后提供最大输入轴位移以补偿每个离合器中的不同摩擦力。 如果在分支中使用正的锁定离合器，则在第二离合器接合之前允许最大输入轴位移，以提供第二离合器的主要和次要部件之间的同步。 在一个实施例中，可调轴承包括推力轴承，其允许输入轴的轴向运动，而输入轴传动装置包括具有相反斜率的螺旋齿圈。 替代实施例包括输入轴上的单个驱动齿轮，其中轴承是可调节的，以允许输入轴轴线的横向移位移动到平行于分支轴的公共平面的平面中。

    Abstract: A power train with an auxiliary creeper drive system is disclosed which includes an engine, a primary transmission having an output shaft selectively driven by the engine, an auxiliary transmission selectively driven by the engine and operatively associated with the output shaft for driving the output shaft at a creeping rate of speed, and a clutch control arrangement for automatically disconnecting the engine from driving engagement with the output shaft when the auxiliary transmission is drivingly coupled thereto. Such auxiliary creeper drive system is particularly adaptable to the transmission of a fork lift truck.

    Abstract: Clutches controlling motion in opposite directions have actuators movable oppositely, said actuators being moved by operating linkage from a control lever which includes lost motion designed to actuate one of the actuators only in one direction of lever oscillation and the other actuator in the opposite direction of lever oscillation. In a special arrangement, the driven part is locked against movement in either direction by manipulation of the normally stationary linkage to cause both disk packs to be engaged simultaneously.
