Embodiment Construction

[0026] figure 1 Shows a side view of a preferred embodiment of a linkage element 4 according to the invention with an arm 42 on the left, a joint 5 adjacent to the arm 42 and a support adjacent to the joint 5 Section 44. On the left side of the arm 42 is schematically shown a bearing eye at which the link element is pivotably connected to the frame of the vehicle, in particular a commercial vehicle. The joint 5 of the linkage element 4 preferably has a first weld 52 which preferably has a lateral seam 56 . It cannot be seen in the figures that the second lateral seam 56 is arranged on the side of the linkage element 4 facing away from the viewer. The link element 4 is welded to the axle tube 2 (not shown) at the lateral seam 56 . exist figure 1 In the illustrated embodiment, the lateral seam 56 is here at an arc angle with respect to the connecting rod axis L Extended, in this example, the arc angle is slightly greater than 180°. Additionally, the side seam 56 has a sid...

Abstract

The invention relates to an axle unit comprising an axle tube and a link element. The axle tube extends substantially along a tube axis, and the link element includes a first joining portion that has a first welding section and a second welding section. The link element is arranged so as to extend substantially transversely to the tube axis and in such a way that the joining portion thereof borders the axle tube. A welded joint between the link element and the axle tube can be formed in the first welding section and the second welding section.

Description

technical field [0001] The invention relates to an axle unit, in particular for commercial vehicles. Background technique [0002] Axle units are known in the prior art, in which an axle tube, usually as a rigid tube, is mounted or fixed in a spring or damped manner via a linkage arrangement on the frame of a commercial vehicle, whereby one or more wheels It is mounted on the shaft tube in a rotatable manner. Here, the connection area between the axle tube and the longitudinal link is a part of the chassis suspension of a commercial vehicle which is particularly heavily loaded and which is particularly subject to cyclic load changes, and many attempts have been made in the past to make the longitudinal link The connection area between the shaft tube and the shaft tube is adapted to the heavy load. In this respect, a number of shaft units are known in the prior art, due to the design of the connection area between the shaft unit and the connecting rod parts for greater safe...
