Abstract
PURPOSE: To accurately control working oil pressure for brakes of left-and-right rear wheels in value corresponding to required, braking force and to prevent the side slipping of the rear wheels, by controlling the starting pressure, for the pressure reducing action of the first and second control valves, to approximately equal.
CONSTITUTION: One end of a common spring 15 for deciding a starting pressure for reducing action of left-and-right rear wheel brakes Br1, Br2 is connected to the brakes. A rear piston 17 of before-and-behind one pair of pistons 16, 17 arranged to contact in series is connected to the other end of the spring 15. Control oil pressure corresponding to the required braking force is each supplied to a front oil pressure chamber 18 formed to the front of the front piston 16 and a rear oil pressure chamber 19 constructed in the both pistons between the first and second gravity valves 221, 222, higher oil pressure acts first the rear piston 17 or the both pistons 16, 17 are operated, the set load of the spring 15 is adjusted, starting pressure for the pressure reducing action of both control valves 51, 52 is controlled to approximately equal the working oil pressure of the left-and-right rear wheel brakes is controlled correspondingly to the required braking force thus the side slipping of rear wheels is prevented.
