1. An axle receiving arrangement for fixing to an axle, the axle receiving arrangement comprising:
multiple components movable in opposite directions with respect to an axle received by the axle receiving arrangement;
a pressure bracket to apply a compressive force to the axle;
a tension bracket including a thread in engagement with a thread of a nut;
wherein the thread of the tension bracket is disposed on a tension bracket upper part, starting on an underside of the tension bracket upper part and terminating below an upper side of the tension bracket upper part; and
wherein a circumferential annular gap on the upper side of the tension bracket upper part is defined by the termination of the thread below the upper side;
at least two components can be combined with one another and one of said at least two components participates in a positive-locking and non-positive locking fixing of the axle and the other of said components ensures the movability in the direction of the axle;
the at least two components enclose a gap in the combined state;
one of the at least two components has a convex underside facing a concave upper side of the other component;
the component that lies against an axle surface in the case of the positive-locking and non-positive locking fixing of the axle has the convex underside;
the component that lies against the axle surface in the case of the positive-locking and non-positive locking fixing of the axle has a V-shaped contact surface;
on the one hand contact sites of the V-shaped contact surface result on the axle surface and also on the other hand contact sites result between the convex underside of the component that lies against the axle surface and the concave upper side of the other component; and
a first gap between the contact sites on the V-shaped contact surface is smaller than a second gap between in each case an inner end of the contact sites of the mutually facing convex and concave surfaces.
