DETAILED DESCRIPTION OF VARIOUS EMBODIMENTS

(5) FIGS. 1 and 3 each show a vehicle for transporting people and/or goods, marked overall with the reference sign 2. Vehicle 2 comprises of at least one frame 4, which in turn comprises at least one frame element 6. The frame element 6 is extended substantially parallel to a longitudinal direction 8 of the vehicle 2.

(6) Wheel carrier 16 and frame element 6 form a receiving area 9 between wheel carrier 16 and frame element 6, in which wheel carrier 16 and frame element 6 are spaced apart from each other enclosing a cavity.

(7) In order to form the receiving area 9, in the exemplary embodiment according to FIG. 1, the frame element 6 comprises of an area 10 that is set back with respect to its extension in the direction of the vehicle 2. The area 10 of the frame element 6 that is recessed towards the vehicle 2 is open towards the outside.

(8) Furthermore, the vehicle 2 comprises a wheel unit 12 which has a wheel 14. The wheel unit 12 is arranged at least in sections in the recessed area 10 of the frame element 6. In order to fix the wheel unit 12, the vehicle 2 comprises of a wheel carrier 16 which can be fixed on the frame element 6, which overlaps the recessed area 10 of the frame element 6 in a fixed arrangement (FIG. 1) and on which the wheel unit 12 is rotatably fixed.

(9) The individual components of the vehicle 2, in particular the wheel unit 12 and the wheel carrier 16, are described in more detail below with reference to FIG. 2:

(10) The wheel unit 12 comprises of a wheel bearing 18, by means of which the wheel unit 12 can be detachably fixed to the wheel carrier 16 in the embodiment example shown in FIG. 2. For this purpose, the wheel bearing 18 comprises of a first wheel bearing element 20 which is non-rotatably and releasably fixed to the wheel carrier 16. In order to secure the first wheel bearing element 20 of the wheel bearing 18 to the wheel support 16, the wheel bearing 18 comprises of a three bolt-shaped securing means 22, each comprising of a head portion at one end and an external thread at the opposite end, which can be inserted through at least one through-aperture 24 in the wheel support 16 and secured in a recess 26 in the wheel bearing 18 in order to join the wheel bearing 18 to the wheel support 16. For this purpose, the recesses 26 in the wheel bearing 18 each comprise of an internal threaded section in which the fixing means 22 can be fixed with an external threaded section opposite the head section.

(11) In addition, the vehicle 2 comprises of a brake unit 28, which comprises of at least one brake disc 30, which is non-rotatably connected to the wheel 14 on the side of the wheel unit 12 facing the wheel carrier 16 and which comprises of at least one clamping means 32 arranged on the wheel carrier 16 by which the brake disc 30 can be clamped. The brake unit 28 can be actuated by a line 34. This can be fixed to the wheel carrier 16 with holding means 36. In order to increase accessibility to the wheel unit 12, two continuous openings 38 are arranged in the wheel carrier 16 in the embodiment example shown in the figures.

(12) In order to fix the wheel unit on the frame element 6, the wheel unit 12 is arranged at least in sections in the recessed area 10. In order to keep the recessed area 10 structurally small, the wheel carrier 16 according to FIGS. 1 and 2 comprises of an integrally formed section 40 opposite the recessed area 10 and extending away from the frame element 6. In the embodiment of FIGS. 1 and 2, the recessed area 10 of the frame element 6 and the section 40 of the wheel carrier 16, which is formed to extend away from the frame element 6, form the receiving area 9.

(13) In order to transport loads, the vehicle 2 comprises of a base plate 42 which is fixed directly to the frame 4, in particular to the frame element 6, and on which at least one additional load can be arranged.

(14) FIG. 3 shows a second embodiment of the vehicle 2, in which the receiving area 9 is formed exclusively by a section 40 of the wheel carrier 16 that extends away from the frame element 6. This allows the frame element 6 to be formed without deformation and without weakening the material.

(15) In the following, the mode of operation of the vehicle 2 is briefly described:

(16) To mount a wheel unit 12 on the frame element 6, the wheel unit 12 is fixed to the wheel support 16 by means of the fixing means 22. For this purpose, the brake disc 30 of the brake unit 28 can first be fixed to the wheel unit 12 in order to then be arranged in such a pre-assembled manner on the wheel carrier 16. According to this, the clamping means 32 of the brake unit 28 can be fixed to the wheel carrier 16 and can be coupled either already pre-assembled to the line 34 or connectable to the line 34. The entire system consisting of wheel carrier 16, wheel unit 12 and brake unit 28 can be fixed to frame element 6 in this way.

(17) The features of the invention disclosed in the above description, in the claims and in the drawing can be essential both individually and in any combination in the implementation of the invention in its various embodiments.
