A pedal unit for a vehicle, comprising: at least one pedal shaft; at least one control cam; at least one pedal and at least one lever arm, wherein the pedal is firmly secured by way of the lever arm to the pedal shaft and wherein the control cam is firmly secured to the pedal shaft; and a pedal plate with a first shaft mount and a second shaft mount, wherein the pedal shaft is mounted by way of the first and second shaft mounts on the pedal plate, wherein the first shaft mount has a first opening with a cross section that is larger than the cross section of a first pedal shaft bearing section of the pedal shaft, by which the fully assembled pedal shaft is introducible into the first shaft mount during an assembly process, and wherein the cross section of the first opening is oval, wherein the second shaft mount comprises a second opening which forms a fit with a second pedal shaft bearing section of the pedal shaft and wherein the fit is formed by a bore with a circular cross section.

2. The pedal unit as claimed in claim 1, further comprising: a bearing bushing arranged at one end of the pedal shaft.

3. The pedal unit as claimed in claim 1, wherein the pedal shaft with the first pedal shaft bearing section is introducible at a slant into the first opening.

4. The pedal unit as claimed in claim 3, wherein the first pedal shaft bearing section of the pedal shaft in a mounted condition of the pedal unit is held by an insert bushing in the first opening of the first shaft mount.

5. The pedal unit as claimed in claim 1, wherein the first pedal shaft bearing section of the pedal shaft in a mounted condition of the pedal unit is held by an insert bushing in the first opening of the first shaft mount.

6. The pedal unit as claimed in claim 1, wherein the pedal unit is a utility vehicle pedal unit.

DETAILED DESCRIPTION OF THE DRAWINGS

(7) FIG. 1 shows in perspective view an exemplary embodiment of a pedal unit 10 according to the invention for a vehicle, here, for a utility vehicle.

(8) The pedal unit 10 includes a pedal shaft 12, a control cam 14, a pedal 16 (see FIG. 2) and a lever arm 18.

(9) Furthermore, the pedal unit 10 includes a pedal plate 20, having a first shaft mount 22 and a second shaft mount 24.

(10) The first shaft mount 22 has a first opening 26 and the second shaft mount 24 has a second opening 28.

(11) Secured firmly on the pedal shaft 12 are the pedal 16 by way of a lever arm 18 and the control cam 14.

(12) The pedal 16 is secured to the lever arm 18 by means of a suitable firm connection on the lever arm 18, e.g. by means of a screw connection, a plug-in connection, or the like.

(13) The lever arm 18 is pressed onto the pedal shaft 12 and then welded at one end to the fastening site. A two-ended weld seam is also contemplated. Alternatively, screw connections, solder connections, or the like, are also possible.

(14) The control cam 14 is fastened similar to the lever arm 18 on the pedal shaft 12. Here as well, the control cam 14 is welded to the pedal shaft 12 at the fastening site by use of a single-ended weld seam. A two-ended weld seam is also usable. Alternatively, screw connections, solder connections, or the like, are also possible.

(15) The pedal shaft 12 is provided at both ends with a first pedal shaft bearing section 30 and a second pedal shaft bearing section 32.

(16) The first pedal shaft bearing section 30 is provided for inserting into the opening 26 of the first shaft mount 22.

(17) The second pedal shaft bearing section 32 is provided for inserting into the opening 28 of the second shaft mount 24.

(18) Furthermore, a restoring element 34 is provided, by which the pedal unit can be returned to a neutral position when the pedal 16 is no longer under load.

(19) The restoring element 34 has a return spring 36.

(20) The return spring 36 engages on the one hand with the pedal plate 20 and on the other hand with the control cam 14.

(21) FIGS. 2 to 6 show the assembly process of the pedal shaft 12 with the control cam 14 and pedal 16 with lever arm 18 firmly fastened to it.

(22) First of all, the pedal shaft 12 is introduced at a slant into the opening 26 of the first shaft mount 22, i.e., with an angle of attack greater than zero, and specifically far enough so that the second pedal shaft bearing section 32 of the pedal shaft 12 at the opposite end of the first pedal shaft bearing section 30 of the pedal shaft 12 is situated between the first shaft mount 22 and the second shaft mount 24.

(23) The second pedal shaft bearing section 32 is then introduced into the opening 28 of the second shaft mount 24.

(24) Both the first pedal shaft bearing section 30 and the second pedal shaft bearing section 32 are then rotatably mounted and fixed with the bearing bushings in the respective openings 26 and 28.

(25) Here, the bearing bushing for the first pedal shaft bearing section 30 and the opening 26 of the first shaft mount 22 are adapted by their outer contour to the inner cross section of the opening 26 of the first shaft mount 22, so that the pedal shaft bearing section 30 is also mounted there in an accordingly defined rotatable manner.
