摘要： A cross slope level/torsion control for mobile machines is disclosed. At least two crawler tracks or four wheels or rail bogies are provided for transporting and elevating the frame with at least one crawler track or two wheels or rail bogies on a reference side of the mobile machine and at least one crawler track or two wheels or rail bogies on cross slope side of the mobile machine. At least four jacking points having variable vertical extension are placed between the crawler tracks, wheels or rail bogies and frame with two jacking points being on the reference side of the mobile machine and two jacking points being on the cross slope side of the mobile machine. The reference side of the mobile machine tracks a reference in elevation and adapts a desired reference attitude. An attitude sensor on the reference side of the mobile machine measures the actual attitude of the reference side relative to gravity. Likewise, an attitude sensor on the cross slope side of the mobile measures the actual attitude of the cross slope side relative to gravity. The relative elevation between the two jacking points on the cross slope side of the mobile machine is varied to cause the attitude of the cross slope side of the mobile machine to match the attitude of the reference side of the mobile machine. Finally, a single cross slope sensor varies the elevation of the cross slope side of the mobile machine relative to the reference side of the mobile machine.

摘要翻译： 公开了一种用于移动机器的横向坡度/扭转控制。 提供至少两个履带轨道或四个轮子或轨道转向架，用于在移动机器的参考侧上具有至少一个履带或两个轮子或轨道转向架来运输和升高框架，并且至少一个履带轨道或两个车轮或轨道 转向架在移动式机器的斜坡侧。 具有可变垂直延伸的至少四个顶起点位于履带轨道，车轮或轨道转向架和框架之间，两个起重点位于移动机器的参考侧上，两个顶起点位于移动机器的十字坡面上。 移动机器的参考侧跟踪高程的参考，并适应所需的参考姿态。 移动机器的参考侧的姿态传感器测量参考侧相对于重力的实际姿态。 同样地，移动装置的十字斜坡侧的姿态传感器也可以测量相对于重力的横坡侧的实际姿态。 移动机的十字斜坡侧的两个起落点之间的相对高度变化，使得移动机的横坡侧的姿态与移动机的参考侧的姿态相匹配。 最后，单个交叉斜率传感器改变移动机器相对于移动机器的参考侧的横向斜面的高度。
