Abstract

The invention is directed to a portal axle for low-slung vehicles, comprising a portal housing 1, 1′ into the interior 2 of which is guided proceeding from an axle bracket side a drive shaft 17 on which a drive wheel 3 is arranged so as to be fixed with respect to rotation relative to it, with intermediate wheels 4 which are rotatably mounted on bearing pins 12 in the portal housing 1, 1′ and which can be rotatably driven by the drive wheel 3 and by means of which an output wheel 5 which is arranged in the portal housing 1, 1′ on an output shaft so as to be fixed with respect to rotation relative to it can be rotatably driven, this output wheel 5 projecting into a hub carrier 6 which can be fixedly connected to the portal housing 1, 1′. The drive shaft 17 and the output shaft extend so as to be axially offset, and a brake caliper of a disk brake is arranged radially adjacent to the portal housing 1, 1′. The portal housing 1, 1′ has on its axle bracket side a mounting orifice 9 which can be closed by a closure part and through which the drive wheel 3 and the intermediate wheels 4 can be inserted into the portal housing 1, 1′, wherein the intermediate wheels 4 have a larger diameter …
