TIRE PRESSURE CONTROL DEVICE OF AN OFF-HIGHWAY VEHICLE HAVING PNEUMATIC TIRES

摘要

The invention relates to a tire pressure control device (1) of an off-highway vehicle having pneumatic tires, by means of which tire pressure control device the tire pressures of the vehicle wheels (2a, 2b, 3a, 3b) of at least one vehicle axle (2, 3) of the vehicle can be changed, each pneumatic-tire-comprising vehicle wheel (2a, 2b, 3a, 3b) having a pressure-controlled wheel valve (4a, 4b, 5a, 5b), which is pneumatically connected to a control pressure line (S1, S2) and to a supply pressure line (V1, V2), the control pressure lines (S1, S2) and the supply pressure lines (V1, V2) being assigned valve devices (11, 12, 15, 16), which are or can be pneumatically connected to a compressed-air supply device (6) and can be controlled by an electronic control unit (10) in order to actuate the wheel valves (4a, 4b, 5a, 5b) of one or more of the vehicle wheels (2a, 2b, 3a, 3b) and to control the tire pressures of said vehicle wheels. According to the invention, each of the vehicle axles (2, 3) included in the tire pressure control device (1) is assigned a control pressure line (S1, S2) having a control valve (15, 16), such that each control valve (15, 16) actuates the wheel valves (4a, 4b, 5a, 5b) of a particular axle, and that each of the vehicle sides is assigned a supply pressure line (V1, V2) having at least one supply valve (11, 12), such that each supply valve (11, 12) supplies the vehicle wheels (2a, 2b, 3a, 3b) of a particular vehicle side with compressed air vehicle.
