Abstract

PURPOSE: To establish a rear wheel braking force resembling an ideal brake distribution ratio by making the smaller diameter end portion of a stepped piston face an input oil chamber and the larger diameter end portion of the same face an oil regulating chamber and by connecting the both chambers through a load spring and a G valve mechanism.
CONSTITUTION: A proportioning mechanism 3 is composed of: regulating pistons 6 and 7 of different diameters, which are slidably fitted in the axial direction in stepped cylinders 2 and 2', which are biased to a large diameter cylinder 2' by a regulating spring 5 and which constitute the stepped piston; a control piston 8 which has its one end slidably fitted in a cylinder 6' and supports a load spring 4 under tension together with the regulating piston 7; an annular valve seat 9; an output oil chamber 10, in which the larger diameter flange 8' of the control piston 8 and which has communication with the wheel cylinder of flange 8' of the control of the rear brake; and an input oil pressure chamber 11 which has communication with the master cylinder. With the use of the proportioning valve thus constructed, it is possible to establish a rear wheel braking force which resembles the ideal braking force distributing ratio.
