Pneumatic suspension of a commercial vehicle with axle load switching between rear axle and leading or trailing axle

摘要

the invention relates to a vehicle suspension, which has luftgefederte, driven rear axle (2) and the corresponding pre - and / or nachlaufachse (10) are equipped.the axles (2, 10), at least one druckluftkreis each with at least one luftfederbalg (1), with at least one pressure switch (4) for recording a balgdrucks the driven rear axle (2) and at least one of the rear axle (2) of a pneumatic force st euerleitung (7) connected wechselventil (3) schaltbares 3 / 2 - wegeventil (11) are provided.the 3 / 2 - wegeventil (11) is again a druckverhu00e4ltnisventil (12) of the rear axle (2) is connected to a control unit, and also provided such stated that in relation to the balgdrucks covered a achslastverhu00e4ltnis between powered rear axle (2) and the zugeord the mid - and / or nachlaufachse (10) changed.;the above described technical solution is characterized by the fact that the control cable (7) of the wechselventils (3), two solenoid valves (5, 6) are connected in parallel by the electric energy versorgbare wechselrelais (8) as a function of the rear axle (2) balgdruck covered it is so schaltbar, by a switching operation of the control cable (7) or entlu00fcftbar.
