Load sensing type brake pressure distributing controller

Abstract

Abstract PURPOSE: To prevent rear wheels from wagging phenomenon in such a way that front and rear brake pressure distributing ratio is brought nearer to the ideal characteristics by simultaneously changing operation of G valve with pressure of proportioning valve. CONSTITUTION: When deceleration of a vehicle has arrived at a settled value, G valve 11 detects this deceleration, and makes working, while pressure in a chamber 18 at the time of operating the G valve is enclosed into a pressure enclosing chamber 61 of a pressure transmission controller 44. Then, pressure in a second input chamber 41 of a proportioning valve 43 is transmitted without receiving any modification through a brake valve 2. In reference to the pressure in a control chamber 67, the pressure in a pressure rise delay device 12 is transmitted, a control piston 81 moves to the left by the differential pressure with the pressure enclosing chamber 61, a change-over valve part 63 is changed over at th same time with the operation of the G valve 11, the proportioning valve 43 reduces the pressure distributing ratio to the front wheels, which is transmitted to the rear wheel brake chamber.
