摘要： A mobile work machine has a loadbearing frame and a drive unit. A covering unit can be moved for into and out of a covering position covering a loadbearing frame opening for covering the drive unit. At least one closure unit for selectively holding the covering unit in a closure position has at least one first closure element and one second closure element which can be adjusted along an adjustment path relative to the first closure element. The closure unit has at least one obstacle to be overcome during the relative adjustment of the first and second closure element. The obstacle defines a release path during opening which is oriented in the direction of the adjustment path and, defines a fixing path during closing which is oriented in the direction of the adjustment path. The release path for the opening is greater than the fixing path.

摘要： Systems to control movement of a motor grader include a sensor for providing a bounce signal indicative of a bouncing movement of the motor grader, and a controller programmed with instructions that, when executed: receive the bounce signal from the sensor; analyze the bounce signal from the sensor; determine whether the maximum amplitude of the bouncing movement exceeds a threshold; in response to determining whether the maximum amplitude exceeds the threshold, generate an articulation angle command signal to change an articulation angle of the motor grader; and transmit the articulation angle command signal to change the articulation angle.

摘要： The present disclosure provides methods for adjusting steering angle and articulation angle in an auto articulation operation of a work vehicle. The percentage of travel of a steering joystick of the work vehicle at least partially determines a steering desired angle change, which can be used to calculate a steering desired angle and an articulation desired angle change. The difference between the steering desired angle and a steering angle detected by a steering angle sensor is used to adjust the steering angle. The articulation desired angle change can be used to calculate an articulation desired angle. The difference between the articulation desired angle and an articulation angle detected by an articulation angle sensor is used to adjust the articulation angle.
