ABSTRACT:
A control (51, 151) for automatically effecting a lock-out of an interaxle differential (14) of a wheeled vehicle (10). The control is arranged to sense a deflection of one of the axles (22) of the wheeled vehicle utilizing a springy beam (24, 124) mounting for transmitting a sensible signal through interconnecting structure (36, 136, 38, 50) from the deflectable beam to the lock-out lever (37) of the interaxle differential (14). In one form, the beam is made to be springy by being provided with a tapered end portion (32) connected through the linkage (36) and in another form, the beam connection to the linkage (136) is through a leaf spring (152). A stop (155) may be provided for limiting the deflection of the axle being sensed.
