Abstract: A mobile machine includes front and rear ends, a frame, rotatably supported ground engaging mechanisms, and an electrical drive system. The electrical drive system includes a source of electrical energy, an inverter, at least one electric motor operatively coupled to rotate at least one of the ground engaging mechanisms, a plurality of first electric cables electrically coupling the source of electrical energy to the inverter, and a plurality of second electric cables electrically coupling the inverter to the electric motor. The inverter is disposed in the mobile machine in a vertical orientation at the rear end of the machine.

Abstract: A control system for a work implement of a machine having a frame is provided. The control system includes a pair of lift cylinders operatively coupled to the work implement and configured to raise or lower the work implement with respect to the frame. Each of the lift cylinders has a rod end and a cap end. The control system includes a first cross-over line configured to fluidly communicate the rod ends to each other and a second cross-over line configured to fluidly communicate the cap ends to each other. The control system includes a cross-over valve disposed in one of the first and second cross-over lines and configured to regulate a flow of hydraulic fluid therethrough. The control system further includes a controller communicably coupled to the cross-over valve and configured to at least partially close the cross-over valve during a dump cycle of the work implement.
Abstract translation: 提供了一种具有框架的机器的工作装置的控制系统。 控制系统包括一对可操作地联接到工作工具并且构造成相对于框架升高或降低工作工具的提升缸。 每个提升缸具有杆端和帽端。 控制系统包括：第一交叉线，其配置成将杆端部彼此流体连通;以及第二交叉线，其配置成将帽端部彼此流体连通。 控制系统包括设置在第一和第二交叉管线中的一个中并被构造成调节通过其的液压流体流动的交叉阀。 所述控制系统还包括可通信地联接到所述交叉阀并被配置为在所述工作装置的转储循环期间至少部分地关闭所述交叉阀的控制器。

Abstract: A braking system is disclosed. The braking system may include a controller configured to determine a power limit for one or more brakes of a machine based on a temperature of the one or more brakes during engagement of the one or more brakes according to a commanded power. The power limit may be a power at which the temperature of the one or more brakes ceases to increase. The controller may be configured to determine a speed adjustment for the machine based on the power limit and the commanded power, and cause adjustment to a speed of the machine based on the determined speed adjustment.
