摘要： A hydraulic circuit (44, 52, 60) for an actuator 18) that has a piston (64) and piston rod (65) that will move a load in a first direction, and which can be externally loaded in an opposite direction, includes a flow compensated valve (60) between the actuator and a control valve (52). When the piston (65) in the actuator (18) is moved in the second opposite direction under the external load and the rate of flow of fluid out of the actuator (18) through the flow compensated valve (60) exceeds a selected rate, an orifice (62) is in the flow path restricts flow from the actuator (18).

摘要： A track driven vehicle (100) comprises a structural member (400, 405 and/or 410) underneath the vehicle. The structural member includes a plurality of structural member apertures (425) for receiving fasteners inserted therethrough. The vehicle also includes a first track carrier (305) and a first mounting strut (110) attached to the first track carrier. The first mounting strut, which attaches the first track carrier to the structural member, includes a plurality of mounting strut apertures (125) which, when aligned with the structural member apertures, receive the fasteners inserted therethrough. One of the first mounting strut and the structural member includes a fixedly attached dowel pin (130), and the other of the first mounting strut and the structural member includes a pin receiving aperture (430). When attaching the first track carrier to the structural member using the first mounting strut, the dowel pin extends into the pin receiving aperture to prevent cross-shearing between the structural member and the first mounting strut. This reduces camber between the structural member and the track carrier and allows fewer fasteners to be used to attach the first track carrier to the structural member.
摘要翻译：轨道驱动车辆（100）包括在车辆下方的结构构件（400,405和/或410）。结构构件包括用于接收插入其中的紧固件的多个结构构件孔（425）。车辆还包括附接到第一轨道载体的第一轨道载体（305）和第一安装支柱（110）。将第一履带支架附接到结构件上的第一安装支柱包括多个安装支柱孔125，当与结构件孔对准时，它们接收插入其中的紧固件。第一安装支柱和结构构件中的一个包括固定连接的定位销（130），并且第一安装支柱和结构构件中的另一个包括销接收孔（430）。当使用第一安装支柱将第一轨道支架附接到结构构件时，定位销延伸到销接收孔中以防止结构构件和第一安装支柱之间的交叉剪切。这减少了结构构件和履带架之间的弯度，并且允许使用较少的紧固件来将第一轨道承载件附接到结构构件。

摘要： A method of operating a hydraulic motor (90; 97). In one embodiment, the method includes measuring (115) a temperature of hydraulic fluid associated with the hydraulic motor and comparing (160; 205; 230) the measured temperature of the hydraulic fluid to a first temperature threshold. The method also includes controlling (165; 170; 210; 213; 215; 225; 235) an operational state of one or more hydraulic motor functions based at least partially on the comparison of the measured temperature of the hydraulic fluid and the first temperature threshold.
