    摘要： A hydrostatic transmission may be placed in a free-wheeling state by rotating a bypass actuator that lifts the motor from a motor running surface whereby hydraulic fluid flows into a transmission cavity. A bypass arm connected to the bypass actuator and to a bypass rod may be used to engage and disengage the bypass actuator via operation of the rod. Further, a bypass latch may be used to lock the bypass arm in an engaged position whereby the bypass actuator is engaged and the transmission is disengaged. The bypass latch arm is preferably linked to the brake pedal whereby actuation of the brake pedal disengages the bypass actuator through operation of the latching arm. The system may be designed to provide dynamic braking through transmission resistivity prior to application of a brake force to the axles or wheels by unlatching the bypass arm prior to actuating the brake arm.

    摘要翻译： 静液压变速器可以通过旋转从马达运行表面提升马达的旁路致动器而放置在续流状态，从而液压流体流入传动腔。 连接到旁路致动器和旁路杆的旁路臂可以用于通过杆的操作来接合和分离旁路致动器。 此外，可以使用旁路闩锁来将旁路臂锁定在接合位置，由此旁路致动器接合并且变速器被分离。 旁路锁定臂优选地连接到制动踏板，由此制动踏板的致动通过闩锁臂的操作使旁路致动器脱离。 该系统可以被设计成通过在致动制动臂之前解锁旁路臂而在通过制动力施加到轴或车轮之前通过传动阻力来提供动态制动。

    摘要： A hydrostatic transmission design incorporating a unique housing shape and configuration, including a vertical split of the two casing elements, which are shaped to conform to the internal components of the transmission. The center section of the transmission has a unique configuration including a trunnion mounted swash plate, means for mounting the center section to the transmission and a motor output shaft mounted below the pump running surface. The transmission also includes an expansion chamber, preferably secured externally to the sump, having a tube mounted therein to transfer hydraulic fluid between the chamber and the sump.

    摘要： A charge pump design for a hydraulic drive apparatus such as a hydrostatic transmission, integrated hydrostatic transaxle or pump having a rotatable pump cylinder block mounted in a sump and connected to a hydraulic circuit by means of a center section or the like. A fluid gallery for charge fluid is in communication with the hydraulic circuit and the charge pump is mounted adjacent to and is driven by the pump cylinder block to provide hydraulic fluid from the sump to the fluid gallery. The charge pump can be of many different styles such as a gerotor, a centrifugal pump or a flexible impeller style.
