Document Type and Number:
Japanese Patent JPH0818573
Kind Code:
B2
Abstract:
Clutch-brake steering systems are known to operate on track vehicles which are highly reliable and cost effective, but lacked the fine degree of controllability found in the more expensive differential steering. An electronically controlled clutch-brake steering control apparatus provides control signals to electrohydraulic proportional valves for accurately modulating the control pressures of a set of steering clutches and brakes. A pair of sensors deliver signals, which are indicative of track speed, to the control apparatus. The apparatus acts to adaptively adjust selected ones of the valves to maintain a desired track speed differential. Thus, the controllability of the clutch-brake steering system is enhanced to effectively compete with more expensive and complex systems.
