The invention relates to an integrated travel limit gear train, which is formed by a portal axle gear train and a planetary gear train, which are combined into one assembly. It is used in portal drive axles, especially in earthmoving, construction and forestry machines. The object of the invention is to reduce the dimensions, the overall size and the weight by integration of the two gear trains to form one unit and to arrive at a modification of the track width. The invention lies in the fact that the basic support part is formed by a partition in the form of an oval plate, which is provided on one side with round cast-on lugs, the bearing of the gear shaft being supported in the upper, round cast-on lug, and the bearing in which the planet wheel drive carrier is supported by means of the hollow journal being supported in the lower, round cast-on lug, a circular recess being provided in the hollow journal for the bearing in which the gear shaft is supported, at least two of the bearings partially overlapping widthwise.
