ABSTRACT:
Multiple control linkages are provided between pivotally connected frames of a vehicle such that no change in the linkage geometry takes place due to the pivotal movement of one frame relative to the other. Specifically, in single or double articulated vehicles, the control levers or pedals are mounted on a first frame with the function that is to be operated being mounted on a second frame that is pivotally connected to the first frame about a pivot. Translation motion of links by movement of the levers or pedals is converted to rotary motion, which motion is transmitted from elements on the first frame by double universal joints to elements on the second frame where the rotary motion is converted to translation or other motion for controlling the operation of a functional piece of equipment, such as the throttle, transmission range or direction selection, or the bucket lift or tilt control. Linear slip is provided for the universal joints to accommodate for changes of length caused by turning one frame relative to the other.
