Problems solved by technology

[0018] In view of the requirements of vehicles with an electric drive, such vehicles generally have higher starting torques and larger wheels, and correspondingly higher compression in the toothing, in order to avoid the above-mentioned sliding and the associated sound formation, It is more difficult to achieve an economical manufacturing process with the two boundary conditions "can be joined by hand" and higher extrusion in the screwed state
The manufacturing tolerances of the mating toothing must be strictly limited for this, which leads to complex and expensive manufacturing
[0019] The helix angle also leads to different behavior in the power transmission depending on the torque direction, which is disadvantageous for the connection design with regard to robustness

Embodiment Construction

[0043] figure 1 An installation situation of the adapter connection according to the invention is shown as an example. The wheel bearing 1 of the wheel with the hub 10 and the joint outer part 2 of the constant velocity joint of the half shaft with the journal 20 can be seen.

[0044] The journal 20 is inserted axially into the hub 10 and is clamped axially relative to the hub 10 by means of a clamping device 30 . In the present example, fastening bolt 31 is represented as clamping device 30 , which is supported with head 32 on wheel flange 40 and via the wheel flange on hub 10 of the wheel bearing. The fastening screw 30 is screwed at the end into a corresponding threaded opening 21 of the journal 20 .

[0045] In a modification of this exemplary embodiment, a threaded section can be provided on the journal 20 at the end, onto which a fastening nut is screwed as clamping device 30 , the fastening nut itself being supported on the hub 10 .

[0046] figure 1 shows the wheel...

Abstract

The invention relates to an adapter connection comprising a hub having a tooth profile on an inner circumferential surface, a journal having a tooth profile on an outer circumferential surface section and a shoulder for axially supporting and / or abutting the hub, and a clamping device for axially clamping the journal to the hub. The hub has a constant tooth profile over its tooth length. The journal has a first section and a second section having different tooth profiles in its tooth length. The first section is arranged on the insertion side, i.e. Further from the shoulder than the second section, and has a constant tooth profile which has a clearance with respect to the tooth profile of the hub. The second section is arranged on the shoulder side and has a tooth profile with a smaller tooth space than the first section, which tooth profile is play-free with respect to the tooth profile of the hub. Only after the first section is inserted into the wheel hub in a clearance-free manner, the second section can be pressed against the tooth profile of the wheel hub in a clearance-free manner by subsequently tightening the clamping device. The invention also relates to a method for toothing a journal.

Description

technical field [0001] The invention relates to a fitted connection comprising a hub with a toothing on the inner peripheral surface; a journal with a toothing on the outer peripheral section and for axial support and and / or a shoulder against the hub; and clamping means for axially clamping the journal to the hub. Background technique [0002] Adaptive connections of this type are often used in vehicle construction in order, for example, to connect a drive joint shaft with a driven wheel. Here, the journal of the drive joint shaft is clamped on the hub of the wheel bearing by means of a screw connection, as in figure 1 as shown in the example. The screw connection can be arranged here on a short journal or on a long journal with an external thread by screwing the fixing bolt as clamping device into the end side of the journal, the nut is screwed as clamping device into the on the long journal. Other clamping arrangements are also possible. [0003] The clamping device ...
