Bei der Erstmontage kann eine ungeteilte Bremsscheibe montiert werden, die vor dem Demontieren gebrochen werden muss. Auch bei geteilten Bremsscheiben ist für den Bremsscheibenwechsel ein axialer Freiraum notwendig, um die Bremsscheibe demontieren zu können. Die Bremsscheibe wird üblicherweise mittels eines Sicherungsringes gehalten.It is known from the prior art to use a split brake disc to assemble and disassemble it to facilitate, since neither the wheel head disassembled nor the brake caliper must be dismantled. When installing for the first time, an undivided Brake disc to be mounted, broken before disassembly must become. Even with split brake discs is for the brake disc change an axial clearance is required to disassemble the brake disc to be able to. The brake disc is usually held by a circlip.

Bei Fahrzeugen mit Radnabenantrieb muss nach dem Stand der Technik trotz der Verwendung einer geteilten Bremsscheibe der gesamte Radkopf demontiert werden, wenn kein axialer Bauraum beansprucht werden soll.For vehicles with wheel hub drive according to the state of the art, despite the use of a split Brake disc of the entire wheel head can be dismantled if no axial Installation space should be used.

Demnach wird vorgeschlagen, das Verbindungsprofil an der Bremsnabe derart auszubilden, dass bei der Montage und Demontage die Bremsscheibe axial von der Außenseite des Fahrzeugs in Richtung Fahrzeugmitte eingelegt wird. Hierbei wird die Bremsscheibe mittels Federelementen axial gehalten.Accordingly, the connection profile is proposed on the brake hub in such a way that during assembly and disassembly the brake disc axially from the outside of the vehicle Vehicle center is inserted. Here, the brake disc is by means of Spring elements held axially.

Dadurch ist es möglich, die Bremsscheibe bei unzerlegtem Radkopf auszutauschen, ohne axialen Bauraum zu verschenken. Zudem wird durch die erfindungsgemäße Konzeption eine sehr kompakte Bauweise erzielt.This makes it possible for the brake disc to replace the dismantled wheel head without wasting axial installation space. In addition, the design according to the invention results in a very compact design achieved.

Durch das Motorgehäuse des E-Motors ist es nicht möglich, wie bei Standard-Achsen, die Bremsscheibe beim Montieren und Demontieren in Richtung Fahrzeugmitte zu verschieben. Es ist daher notwendig, dass auch bei der Erstmontage eine geteilte Bremsscheibe verwendet wird.Through the motor housing of the Electric motors it is not possible as with standard axles, the brake disc when assembling and disassembling to move towards the center of the vehicle. It is therefore necessary that a split brake disc is also used for the initial assembly becomes.
