MACHINE EMPLOYING CAB MOUNTS AND METHOD FOR CONTROLLING CAB MOUNTS BASED ON MACHINE LOCATION

摘要

A machine (100) employing controllable mounts (106) and a method for controlling such mounts (106) based on machine location are disclosed. The controllable mount (106) may include a housing (108), a pin (120), rheological fluid (116) within the housing (108) and coils (131) provided proximate to the rheological fluid (116). As current is applied to the coils (131), the apparent viscosity of the rheological fluid (116) is increased, and in so doing so is the stiffness of the controllable mount (106). Depending on machine location, however, the operator may want differing levels of stiffness in one or more of the controllable mounts (106). For example, when roading on rocky terrain, the operator may want relatively loose mounts (106) so as to absorb the large vibration inputs and make for a more comfortable ride. The present disclosure therefore identifies the machine location through global positioning satellite information, topography maps, inclinometers, altimeters, operator input, and the like and controls the current to the coils, and thus the relative stiffness and damping of the controllable mounts, accordingly.
