Problems solved by technology

Therefore, there is no guarantee that the sheath can be arranged on the shaft tube, for example in an ideal form-fitting manner
However, in order that the sheath can be seated on the shaft tube in a sufficiently good state, further finishing works of the sheath or of the shaft tube have to be carried out, or different sheaths with different inner diameters have to be provided

Embodiment Construction

[0054] Figure 1a A preferred embodiment of the compensating portion 40 with a parting line 48 is shown. On both sides of the parting line 48 in the circumferential direction U, two corresponding webs 46 extend, and each of these two webs 46 also has a corresponding inner gap 42' in the circumferential direction U. Adjacent ways are laid out. Substantially opposite the inner gap 42' in the radial direction, the outer gap 42" is arranged on the outer contour 24. When viewed in the circumferential direction U, the outer gap 42" at the outer contour 24 has substantially The gap width Ba substantially corresponds to the gap width Bi of the inner gap 42 ′. Advantageously, the gap width Ba on the outer profile 24 can also be formed to be larger than the gap width Bi of the inner gap 42', so that when the sheath 20 is fully compressed, the outer gap 42" of the outer profile 24 is still filled. Fillet welds (filletweld) leave enough space. Through the compensation part 40 of the she...

Abstract

A wrap (20) for attaching a suspension arm to an axle tube, having a substantially tubular cross-section which extends along a longitudinal axis (L) and which has an outer contour (24) and an inner contour (22), wherein the inner contour (22) has an internal diameter (Di), and wherein the wrap (20) has at least one compensation portion (40) which extends substantially along a longitudinal axis (L), and wherein the at least one compensation portion (40) is designed to modify the internal diameter (Di) by way of different adjustments.

Description

technical field [0001] The present invention relates to a boot for mounting a suspension arm or trailing arm to an axle tube, and to a method of manufacturing the combination trailing arm and axle tube and a trailing arm for the axle tube. Background technique [0002] Such boots are commonly used in the field of axles, especially rigid axles (controlled or uncontrolled rigid axles). Typically, such an axle consists of an axle tube and two trailing arms forming a connection to the vehicle frame or chassis. Due to the sheathing, the trailing arms are no longer welded directly to the axle tube, which would have a negative impact on their service life. Instead, the trailing arm is welded to the sheath, which is then connected to the axle tube. The problem is that the shaft tubes or their outer diameters exhibit certain tolerance ranges due to the manufacturing process. Therefore, there is no guarantee that the sheath can be arranged on the shaft tube, for example in a perfec...
