  • Combined steering and braking means for crawler tractor
    Patent number: 4137944
    Abstract: A crawler tractor has an engine-driven fluid power shifted transmission for supplying motive power to left and right crawler tracks through spring-applied fluid-released left and right steering clutches and also has spring-applied fluid-released brake actuators for the track brakes. A hydraulic control system for steering and braking the tractor includes a combined steering and braking valve having a pair of lever operated valve spools, a shuttle valve, and a supplemental brake control valve operated by a single brake pedal. The combined steering and braking valve, which includes a flow divider, directs fluid from a pump to the brake actuators to maintain the brakes released when the valve spools are in neutral. When a lever operated valve spool is moved from neutral to some other position, the combined steering and braking valve directs fluid to disengage a clutch and causes the brake for the associated track to be applied.
