Converted four wheel drive vehicle

The engine drive unit is operationally connected via a propeller shaft with the opening to the transmission drive. The transmission drive has an open flanged side covered by a sealing element, that is a sealing plate, which protrudes from the outer contour of the housing. A frame fastened to the side of the transmission drive holds a U-profile which covers the cross member of the chassis, in particular its recess, whereby the U-profile has a corresponding sealed bulging.
