Device for quickly resetting a pneumatic suspension to normal operating level

摘要

The present invention relates to a system for regulating a pneumatic suspension, comprising a pneumatic concertina (1) making the connection between a non-suspended mass formed by an axle (3) and a suspended mass formed by the chassis (2) of a road vehicle. Said system comprises, furthermore, means for putting the pneumatic concertina (1) in high-flow communication with the compressed-fluid circuit when the distance between the suspended mass and the non-suspended mass exceeds the maximum negative deflection in road use and/or for putting the concertina in communication with a high-flow exhaust valve (15) when said distance exceeds the maximum negative deflection. The invention is used for road vehicles, trailers and semi-trailers. IMAGE
