Abstract

PURPOSE: To eliminate the deviation in the ideal braking ratio of front and rear wheels in accordance with to the load upon a vehicle, by providing a spring force urging mechanism for applying the force of a control spring to the control piston of a proportioning mechanism.
CONSTITUTION: A spring force urging mechanism including a piston 34 etc. is provided to apply the force Fx of a control spring 37 to the second control piston 16 of a proportioning mechanism 1. The break value Pc of output liquid pressure control is proportional to the spring force Fx. The break value Pc is related as Fx= Fo+KP (Fo denotes the initial spring force) by the holding liquid pressure Pc of an adjusting liquid chamber C that one end of a piston 34 faces. Braking liquid pressure required to achieve such a prescribed deceleration that a fluid passage 32 is closed by the G valve mechanism 2 of a vehicle controller. For that reasons, the spring force Fx applied to the piston 16 is augmented according as load increases. As a result, the change rate of the spring force Fx can be altered depending on the varying condition of an ideal braking force distribution curve, by changing the value of the coefficient K of said formula.
