Title:
ANTISKID DEVICE
Document Type and Number:
Japanese Patent JPS5372969
Kind Code:
A
Abstract:
There is provided a wheel lock-up prevention device for compressed air operated brakes of a motor vehicle which includes a common control of the pressure in the brakecylinders of a given wheel axle. The control is accomplished by means of multi-position main valves which include magnetic pre-control valves with identical control magnets and with armatures having integral closure bodies. Furthermore, the valve bodies of the multi-position valves are substantially identical at least on their pressure side. The use of such simple and identical valves provides a modular-like construction making possible a selective 2-point or 3-point operation as well as a single-duct or a multi-duct embodiment of the wheel lock-up prevention device. Thus, during a functional test at the beginning of a trip, a dangerous and hence undesired release of the brakes when parked on an incline is prevented by means of the actuation of all of the magnets.
