ELECTRONIC-PNEUMATIC BRAKING SYSTEM, FOR EXAMPLE FOR A HEAVY GOODS VEHICLE OR ARTICULATED TRUCK

摘要

An electronic-pneumatic braking system for a vehicle, for example for a heavy goods vehicle or an articulated truck, includes a TCS/ESC modulator (1), enabling control functions for a traction control system (TCS) and a vehicle stability control system (ESC). The TCS/ESC modulator (1) includes a pneumatic relay valve (2), a solenoid valve (7) and a changeover valve device (11). In order to achieve a compact size and cost savings during manufacture, only control pressure can be applied to the solenoid valve (7) and to the changeover valve device (1), while only the pneumatic relay valve (2) has a large nominal size for conveying the supply pressure to at least one wheel brake and for venting the latter. As a result, the changeover valve device (11) can be structurally integrated in a TCS/ESC modulator (1) intended for carrying out the TCS/ESC functions.
