Transmission control mechanism for a tractor having a resiliently-mounted control console
Abstract
Abstract A TRACTOR IS PROVIDED WITH AN OPERATOR''S STATION INCLUDING A PLATFORM, SEAT, AND CONTROL CONSOLE WHICH ARE SECURED AS A UNIT TO THE TRACTOR CHASIS BY RESILIENT MOUNT ASSEMBLIES WHICH PROVIDE VIBRATION ISOLATION AND PERMIT LIMITED VERTICAL MOVEMENT OF THE OPERATOR''S STATION RELATIVE TO THE TRACTOR CHASSIS. A TRANSMISSION SPEED AND RANGE CONTROL MECHANISM FOR SELECTIVELY ESTABLISHING DESIRED CONDITIONS IN THE TRANSMISSION IS FIXED TO THE CONTROL CONSOLE AND INCLUDES SPEED AND RANGE SELECTOR DRUMS SELECTIVELY PIVOTALLY MOUNTED FOR ROCKING ABOUT A COMMON AXIS, WHICH DRUMS HAVE RIGID LINKS CONNECTED THERE- TO AND TO TRANSMISSION SHIFT ELEMENTS FIXED TO THE CHASSIS. TO PREVENT THE TRANSMISSION FROM BEING SHIFTED DUE TO RELATIVE MOVEMENT BETWEEN THE OPERATOR''S STATION AND THE TRACTOR CHASSIS, A COMPENSATOR LINKAGE IS CONNECTED BETWEEN THE CHASSIS AND SELECTOR DRUMS IN SUCH A WAY AS TO GUARANTEE THAT NO MOVEMENT IS IMPARTED TO THE RIGID LINKS CONNECTING THE SELECTOR DRUMS TO THE TRANSMISSION SHIFT ELEMENTS.
