    摘要： A parking brake is controlled in concert with operation of a hydrostatic power unit of a continuously variable transmission, particularly when engaging, disengaging and shuttle shifting the transmission, to provide advantages, particularly when on hills. When particular commands are received, such as shifting to a non-moving position, the parking brake is automatically engaged to hold the vehicle position. A swash plate of the hydrostatic unit can be automatically positioned to anticipate the next command. If that command is received, the brake is automatically gradually or proportionally released and the transmission engaged to effect the commanded movement of the vehicle. If a different command is received, the brake remains engaged as the transmission is configured for the commanded movement, such that no machine movement results. Then the brake is automatically gradually or proportionally released and the transmission engaged to effect that commanded movement.

    摘要翻译： 一个驻车制动器与无级变速器的静液压动力单元的操作一起被控制，特别是当接合，脱离和往复移动变速器时，特别是在小山上时，提供了优点。 当接收到特定命令时，例如转移到不移动位置时，驻车制动器自动地接合以保持车辆位置。 静压单元的旋转斜盘可以自动定位，以预测下一个命令。 如果接收到该命令，则自动逐渐或成比例地释放制动器，并且变速器接合以实现车辆的指令运动。 如果接收到不同的命令，则制动器保持接合，因为变速器被配置为用于指令的运动，使得不会导致机器运动。 然后，制动器自动逐渐或成比例地释放，并且变速器接合以实现该指令的运动。

    摘要： A method of calibrating a hydraulically operated park brake of a continuously variable transmission of a vehicle. With the vehicle moving at a set, slow speed within a specified range, and the park brake off, a search technique is used, wherein the brake hydraulic pressure is reduced by application of a control signal of a selected test value to apply the brake. When the selected test value is reached, it is held constant, and a condition in a HSU of the transmission is monitored for a change indicative of engagement of the park brake. This will expectedly be in the form of a pressure change and more particularly an increase indicating initial contact between the plates of the brake, and if the HSU change is not detected, the step will time out and another control signal value will be tested.

    摘要： A mechanical drive clutch is provided for mounting on a rotatable shaft. The drive clutch includes a drive gear having a plurality of gear teeth projecting therefrom. A sleeve is slidably mounted on the shaft for rotational movement therewith. The sleeve includes a plurality of gear engagement recesses therein of arcuate lengths greater than the predetermined arcuate lengths of the gear teeth. The sleeve is moveable between a first retracted position and a second engaged position wherein the gear teeth are received within corresponding gear engagement recesses in the sleeve in order to translate rotation of the drive gear to the shaft. A plurality of anti-backlash elements are provided to compensate for the difference in the arcuate lengths of gear teeth and their corresponding gear engagement recesses in the sleeve.
