Interlocking building block for holding a wheel

Interlocking building block (23) for holding a wheel (13) in an interlocking building block model (2), comprising:

• a hub flange (24) rotatable about a rotational axis (26) with a front side as seen in the direction of the rotational axis (26) and a rear side opposite the front side,
• wherein on the front side, radially spaced from the rotational axis (26), at least two form-fit elements (56, 28) acting in the circumferential direction about the rotational axis (26) for transmitting a torque acting about the rotational axis (26) to the wheel (13) are held, and
• a hub pin (38) held on the rear side concentrically to the rotational axis (26) on the hub flange (24) for mounting the hub flange (24) on a wheel suspension (44),
• characterized by
• a bearing element (32) independent of the form-fit elements (56, 28) for axially holding a retaining means (58) which is configured to block an axial movement between the wheel (13) and the hub flange (24).
