Steering apparatus with a blocking device for limiting a steering angle of rotation, and steer-by-wire steering system with such a steering apparatus

A steering apparatus includes a blocking device for limiting a steering angle of rotation, wherein the blocking device includes a blocking element movable between a locking position and a release position and a shaft mounted rotatably about its centre longitudinal axis, wherein, in the locking position, the blocking element interacts with a blocking contour, which is connected to the shaft for rotation therewith, in order to stop a rotational movement of the shaft, and the blocking device includes at least one of an electromagnetic or a electromechanical actuator, wherein the blocking element is movable by the actuator for interaction with the blocking contour, wherein the steering angle of rotation can be limited in two directions of rotation directed facing away from each other by the blocking element, wherein both a first end stop position in a first direction of rotation and a second end stop position in a second direction of rotation opposed to the first direction of rotation can be predefined by the blocking element and in interaction with the blocking contour.
