Abstract

PURPOSE: To cause a controller for the expansion and contraction of a single brake cylinder to fulfill a positive brake function and a negative brake function, by using change-over valves and a variable control valve.
CONSTITUTION: The first passage from an air pressure distribution valve 55 is connected through a change-over valve 56 to a clutch cylinder 45 which acts to change running and turning for each other. The second passage is connected to an operating valve 57 and change-over valves 67, 70 through a parking valve 63. The third passage is connected to the change-over valve 70 through a variable control type foot valve 58. When the change-over valve 56 is operated depending on running or turning, the change-over valves 67, 70 act in response to the operation to that the pressure from the parking valve 63 and the pressure from the foot valve 58 are changed over and transmitted to a running brake 39 and a turning brake 42, respectively. According to this constitution, the brakes can be put in positive operation and in negative operation, respectively, depending on running or turning.
