Level control arrangement for vehicles having air springs |
摘要 |
The invention relates to a level control arrangement for a vehicle having air springs (8) via which the chassis of the vehicle is suspended relative to at least one vehicle axle. A pneumatically-controllable directional-control valve (18) is arranged between the compressor (4) and the air dryer (6) and the directional-control valve (18) has two control inputs (20 and 22). In the base state of the level control arrangement, the compressor (4) is connected via the pneumatically-controllable directional-control valve (18) to the air dryer (6). When the control line (26) of the first control input (20) is connected via a controllable directional-control valve (30) to the atmosphere, the pneumatically-controllable directional-control valve 18 transfers into the other switching state and the air spring (8) can be vented via the air dryer (6). The pneumatically-controllable directional-control valve (18) permits large flow cross sections to be switched so that the air dryer (6) can be rapidly vented when venting the air spring (8) and a regeneration of the air dryer (6) is then possible in an especially advantageous manner.
