Abstract: A compact transmission drive line arrangement incorporating a planetary mechanism comprised of three simple planetary gear sets interconnected having associated therewith two clutches and four brake mechanisms to provide four forward speed ratios and one reverse speed ratio. The clutches and the planetary mechanism are on opposite sides of the final drive gear which is connected to drive a parallel arranged differential and output shaft assembly. The planetary transmission is arranged such that all of the brake mechanisms are disposed radially of the planetary mechanism on the same side of the final drive.

Abstract: A continuously variable transmission including a driving shaft connected to an engine output member and a driven shaft. The shafts are interconnected by a stepless variable coupling. A bidirectional gear drive mechanism connects the driven shaft to a differential mechanism having two output shafts extending therefrom. The drive mechanism includes a two gear forward and a three gear reverse drive path, each of which is controlled by a fluid-actuated starting clutch mechanism. Each gear path is adapted to drive a transfer gear which continually intermeshes with a ring gear of the differential defining another gear mesh. By such construction, the output shafts and the engine output memeber may rotate in the same direction during a forward drive mode of operation.

Abstract: A fluid control system for a continuously variable transmission utilizing a first valve which is manually operable, and a second valve operable by a fluid motor which fluid motor also provides engagement and disengagement of two gear ratios. The first valve directs fluid flow from a fluid source to the fluid motor and to the second valve for communication to a fluid actuated starting clutch. Fluid for the clutch and fluid motor are only provided when the first valve is selectively engaged to the first or second operable gear ratios thereby directing fluid from the fluid source to the fluid actuated motor. The fluid motor is operable to move a gear engaging means and simultaneously move the second valve to an aligned port position permitting fluid flow to the starting clutch. The clutch is only engaged when the manually operated valve is in the first or second gear ratio position, therefore, independent park and neutral positions have been obviated by the fact that such a starting clutch is no longer providing power to an output means. In an alternative embodiment a pressure modulator valve is interposed between the fluid source and the first valve to control the line pressure to the fluid control system. The use of the starting clutch in this fashion obviates the use of a forward clutch to provide driving communication between input and output means.

Abstract translation: 一种用于使用可手动操作的第一阀的无级变速器的流体控制系统，以及可由流体马达操作的第二阀，所述流体马达还提供两个齿轮比的接合和分离。 第一阀将流体流体从流体源引导到流体马达和第二阀，以与流体致动的起动离合器连通。 仅当第一阀选择性地接合到第一或第二可操作的传动比时提供用于离合器和流体马达的流体，从而将流体从流体源引导到流体致动马达。 流体马达可操作以移动齿轮接合装置并同时将第二阀移动到允许流体流到起动离合器的对准的端口位置。 离合器仅在手动操作的阀处于第一或第二档位时被接合，因此，这种起动离合器不再向输出装置供电的事实已经消除了独立的停放和空档位置。 在替代实施例中，压力调节阀介于流体源和第一阀之间，以控制流体控制系统的管路压力。 以这种方式使用起动离合器避免使用前进离合器来提供输入和输出装置之间的驱动连通。
