Adaptive connection

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 ...

AI Technical Summary

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
