Abstract

The drag reducer for an articulated vehicle comprises an extending vertical bulkhead which is set up along the vehicle middle axis between the cab and the front of the trailer. The bulkhead prevents cross winds passing between the cab and trailer resulting in turbulence along one side of the trailer. The bulkhead (5) is mounted in a vertical, folded setting behind the cab and is hung on flexible fittings on the front edge of the trailer. Cornering movements as well as roll and pitch movements do not damage the bulkhead nor impede the driving.
