A steering control valve system for a crawler vehicle has four valve spool bores formed in parallel to each other at equal intervals in a valve body, four valve spools respectively inserted slidably into the four valve bores, four actuator members respectively inserted slidably into the four valve bores so as to respectively actuate the four valve spools, and a link mechanism for operatively connecting between the four actuator members and operating mediators, wherein the valve system is controlled by only a push-in operation of the valve spools. The operating mediators are steering levers and a brake pedal or electric motors and operating buttons.

Steering control valve system for crawler vehicle

A tracked vehicle designed to allow easy dismounting, as for servicing, of a power train assembly comprising a torque converter, a transmission, and a steering mechanism detachably joined together. Having its input shaft coupled to the output shaft of an engine via a joint, the torque converter is supported on a pair of main vehicle frame members via a removable support member extending therebetween. The steering mechanism is mounted to the main frame members both detachably and for pivotal motion about the aligned axis of its pair of output shafts separably connected to respective retractable input shafts of final drives secured externally to the main frame members. Thus the power train assembly is either wholly dismountable from the vehicle frame or pivotable relative to the vehicle frame about the aligned output shafts of the steering mechanism for dismounting only the torque converter and the transmission.
