A CONTROL LINKAGE Abstract of the Disclosure A control linkage is disclosed for a vehicle such that the vehicle's transmission can be connected to a shift lever located in an isolated cab structure. Movement of the shift lever will obtain corresponding shifting of gear ratios within the transmission. The control linkage permits such shifting while compensating for relative motion between the cab structure and the transmission. The control linkage includes a rotatable shaft which is secured between the cab structure and the transmission and which is also capable of angularly moving relative to both structures. A sleeve is positioned about the support shaft and is secured to it so that both can rotate simultaneously. Extending radially outward from the sleeve is a pair of arms, both of which contain a spherical attachment member positioned adjacent to their outer ends. Attached to these spherical connections are first and second rods which are aligned approximately perpendicular to the support shaft. The first rod connects the shift lever to one of the arms while the second rod connects the transmission to the other arm. As relative motion occurs, the support shaft will pivot about one of its ends such that the displacement of the second rod will be less than that needed to displace the gear shift mechanism an undesirable amount.
