Machine employing cab mounts and method for controlling cab mounts based on operator input

摘要

A machine employing controllable mounts and a method for controlling such mounts based on operator input are disclosed. The controllable mount may include a housing, a pin, rheological fluid within the housing and coils provided proximate to the rheological fluid. As current is applied to the coils, the apparent viscosity of the rheological fluid is increased, and in so doing so is the stiffness and damping of the controllable mount. Depending on various factors, the operator may want a particular level of feedback. For example, when fine grading, the operator may want to feel every vibration and thus the controllable mounts should be as stiff as possible. The present disclosure therefore provides the operator with the ability to select the desired level of feedback. This can be done through an operator interface that enables an operator to specifically set the current to each mount, or enter other information whereupon a processor of the control system executes the necessary algorithm to provide the operator with the optimum level of feedback.

1. A machine, comprising:
a frame; an operator cab supported by the frame; at least one moveable implement operatively associated with the frame; a controllable mount operatively connecting the operator cab to the frame,
the controllable mount including:
a housing;a pin mounted within the housing; andcoils positioned relative to the housing to generate a field through the rheological fluid; the operator cab including an operator interface with a plurality of slider bars, one slider bar being associated with the controllable mount and configured for independent control of the controllable mount by the operator, wherein an operator can input a desired level of feedback for the controllable mount independently of another controllable mount; and an electronic control unit operatively associated with the coils and adapted to change a level of current applied to the coils to adjust an apparent viscosity of the rheological fluid based on operator input via the operator interface.
