The invention relates to a device for driving a wheel of a vehicle. The device includes a hub for carrying the wheel in a rotationally fixed manner, a planetary gear connected between a driving axle and the hub, which planetary gear includes a planet carrier which is connected in a rotationally fixed manner to the hub, and an arrangement for fixing the hub and the planet carrier in the intended position relative to one another in the axial direction. Both the hub and the planet carrier include a hole which extends in the axial direction. At least one of the holes forms at least a part of a continuous opening through the hub and the planet carrier in the axial direction. The fixing arrangement comprises an elongate element arranged in the continuous opening and an arrangement for fixing the hub and the planet carrier relative to one another in the axial direction via the elongate element.

What is claimed is: 1. A device for driving a wheel of a vehicle, comprising a hub for carrying the wheel in a rotationally fixed manner, a planetary gear connected between a driving axle and the hub, in which the planetary gear comprises a planet carrier which is connected in a rotationally fixed manner to the hub, and an arrangement for fixing the hub and the planet carrier in the intended position relative to one another in an axial direction, wherein the hub comprises a continuous hole through the hub in the axial direction wherein the planet carrier comprises a continuous opening in the axial direction, wherein at least one of the holes forms at least a part of a continuous opening through the hub and the planet carrier in the axial direction, and the fixing arrangement comprises an elongate element arranged in the continuous opening and a fastener for fixing the hub and the planet carrier relative to one another in the axial direction via the elongate element. 2. The device as claimed in claim 1, wherein a center line through the holes in the hub and the planet carrier coincides with an intended axis of rotation of the hub. 3. The device as claimed in claim 1, wherein the fastener comprises a portion with at least in part a greater extent in the radial direction than the holes in the hub and the planet carrier, and the radially projecting portion is connected to the elongate element so as to form a counterstay at a first end of the continuous opening. 4. The device as claimed in claim 3, wherein the radially projecting portion is plate-shaped. 5. The device as claimed in claim 3, wherein the elongate element and the radially projecting portion are formed in one piece. 6. The device as claimed in claim 3, wherein the radially projecting portion bears against a correspondingly designed surface of the planet carrier. 7. The device as claimed in claim 3, wherein the radially projecting portion comprises at least one first guide surface for guiding interaction with a correspondingly designed surface of the planet carrier. 8. The device as claimed in claim 7, wherein the first guide surface is of cylindrical or conical shape. 9. The device as claimed in claim 1, wherein the fastener comprises one or more interacting tightenable fasteners for tightening the hub and the planet carrier, which tightenable fasteners are arranged at a second end of the continuous opening. 10. The device as claimed in claim 9, wherein the tightenable fasteners comprise a threaded portion on the elongate element and a correspondingly designed nut. 11. The device as claimed in claim 9, wherein the tightenable fasteners is arranged at an axially outer end of the continuous opening in the hub. 12. The device as claimed in claim 1, wherein the elongate element is rotationally symmetrical, and the device comprises a peg for rotational locking of the elongate element relative to the planet carrier. 13. The device as claimed in claim 1, wherein the device also comprises a journal which connects the planet carrier and the hub in the axial direction, and in that the journal comprises the continuous opening for receiving the elongate element. 14. The device as claimed in claim 13, wherein the hub and the journal are formed in one piece. 15. The device as claimed in claim 14, wherein the hole of the planet carrier is adapted for receiving the journal. 16. The device as claimed in claim 13, wherein the fastener comprises a portion with at least in part a greater extent in the radial direction than the hole in the planet carrier, and the radially projecting portion comprises at least one second guide surface for guiding interaction with a correspondingly designed surface of the journal. 17. The device as claimed in claim 16, wherein the second guide surface is of cylindrical or conical shape. 18. The device as claimed in claim 1, wherein the planet carrier and the hub are interconnected in a rotationally fixed manner in relation to one another via positive locking. 19. The device as claimed in claim 1, wherein the planet carrier and the hub are interconnected in a rotationally fixed manner in relation to one another via a spline connection. 20. The device as claimed in claim 13, wherein the journal is provided with external splines and the hole of the hub is provided with internal splines. 21. The device as claimed in claim 1, wherein a friction brake is arranged outside the planet carrier for braking the planet carrier relative to a static housing part. 22. The device as claimed in claim 21, wherein the friction brake comprises a service brake. 23. A work vehicle comprising a device as claimed in claim 1.
