Load-dependent brake pressure regulator for motor vehicle and/or trailer brake systems

Abstract

The invention relates to a load-dependent brake pressure system for a pneumatically activated motor vehicle and/or motor vehicle trailer brake apparatus with an entrance device having an initial entrance phase in which the full control pressure is delivered to the cylinders of the wheel brakes. In an emergency situation, the supply pressure which is available on the vehicle must be able to be conveyed in a graduated and controlled manner as the brake pressure is applied to the wheel brakes. The present load-dependent brake pressure system which, in an emergency situation, makes possible the application of brake pressures which are higher than that corresponding to the control ratio up to the available delivery pressure, includes an entrance valve and piston, a control valve, a brake control piston, a relay valve, auxiliary valves, a control, delivery, brake pressure connections and chambers, and a valve tappet for controlling brake pressures in multiple phases.
