1. A securing device for securing a standstill of a vehicle, said securing device comprising:
a rotatable wheel shaft of the vehicle having a front side that is fixedly connected to a brake disc rotor and a rear side that is opposite the front side,
a securing body that is configured to be mounted to the vehicle by a bearing device, said securing body being movable between a securing position (SP) and a release position (FP) and
a counter-securing body that is fixed to the rear side of the rotatable wheel shaft, the counter-securing body having a fastening portion for a force-transmitting fastening to the wheel shaft of the vehicle, wherein the counter-securing body comprises at least one form-fitting portion in the form of gear teeth disposed on an outer exterior circumferential surface of the counter-securing body for (i) a form-fitting latching to a pawl portion of the securing body in the securing position (SP) and (ii) a release of the pawl portion of the securing body in the release position (FP),
wherein the bearing device is a rotational bearing that guides rotation of the securing body about a securing axis (SA) between the securing position (SP) and the release position (FP),
wherein the securing body and/or the counter-securing body comprise/comprises a force-limiting means for limiting a force transmitted between the securing body and the counter-securing body,
wherein the force-limiting means comprises a spring element for transmitting force between the securing body and the counter-securing body, and
wherein the spring element is a torsion spring having a torsion axis that is aligned with an axis of rotation of the securing body, and wherein the torsion spring is configured to release the securing body from the counter-securing body when a force between the securing body and the counter-securing body exceeds a predefined force threshold.
