Tire pressure as a rule, the system and method for regulating the

摘要

Tire pressure is generally a system for vehicles having a pneumatic tire (2) comprising:– at least one tire pressure sensor (3),– at least one tire valve (7),– at least one pressure distributor (5) with control valves (6, 8, 9),– - a control and regulating unit (10),– a compression coupling (33) to a pressure supply line (11);wherein said - and regulating unit (10) is part of one of the existing motor vehicle control devices, and wherein the tire pressure is generally a system (1) at least a tire-pressure control valve (4), and wherein the pressure distributor (5) a first switching valve (8) a second on / off valve (6) and a third on-off valve (9), and wherein the three on-off valves of four switching positions, wherein– in a first switching position, in which the tire pressure is constant and the tire-pressure control valve (4) is closed, all three on-off valves (6, 8, 9) have a closed position,– in a second switching position, in which the tire pressure is increased and the tire-pressure control valve (4) is open, only the first switching valve (8) an open position to a pressure supply line (11) comprises,– in a third switch position, in which the tire pressure is reduced and the tire-pressure control valve (4) is open, only the second switching valve (6) an open position to a downstream of the switching valve (6) arranged throttle valve (32) and– in a fourth switching position in which the tire-pressure control valve (4) merges into a closing position, only the third on-off valve (9) for a limited time has open position to the ambient pressure.
