Abstract
The present invention concerns an axle unit comprising a stub axle and an axle tube, wherein the stub axle has a longitudinal channel which extends inside the stub axle substantially along a stub axis, wherein the stub axle has a transverse channel which extends inside the stub axle substantially transversely to the stub axis and opens to the environment at the outer face of the stub axle, wherein the longitudinal channel and the transverse channel are connected together, wherein the stub axle has a stub joining region to which the hollow-bodied axle tube can be secured.
Claims19
An axle unit, comprising:
- a stub axle;
- and
- a hollow-bodies axle tube;
- wherein the stub axle has two longitudinal channels which extend inside the stub axle substantially along a stub axis;
- wherein the stub axle has two transverse channels which extend inside the stub axle substantially transversely to the stub axis and open to the environment at an outer face of the stub axle;
- wherein in each case, one of the longitudinal channels and one of the transverse channels are connected together;
- wherein the stub axle has a stub joining region onto which the hollow-bodied axle tube is directly secured;
- wherein a first connecting portion is located on the outer face of the stub axle;
- wherein the transverse channels include opening points that are arranged inside the first connecting portion;
- and
- wherein the first connecting portion, starting from a vertical to the stub axis, has an arcuate extension of maximum 30° to 120°.
A chassis system, comprising:
- an axle unit;
- and
- a suspension arm unit;
- wherein the axle unit has a stub axle;
- wherein the stub axle at least in regions is configured rotationally symmetrical to a stub axis and has a first connecting portion on an outer face of the axle stub;
- wherein the suspension arm unit extends substantially along an arm axis and has an engagement portion;
- wherein the stub axle is configured to be secured to the engagement portion of the suspension arm unit such that the stub axis is oriented transversely to the arm axis;
- wherein the connecting portion is connected to channels of the stub axle and is configured for connection of line elements;
- wherein the engagement portion has a connecting recess which is configured to be arranged on the first connecting portion such that the first connecting portion is accessible via the connecting recess;
- and
- wherein the suspension arm unit is secured to the axle unit in the region of the first connecting portion.
