Abstract

An additional weight for a wheel for ballasting a drive axle of a working machine includes a first loading disk centrally connected to the drive axle and a second loading disk connected to the first loading disk. The first loading disk has a conical abutment face for pre-positioning the second loading disk relative to the first loading disk. The first and the second loading disks form encoding formations for mutually centering on end faces which face each other and which are in engagement with each other in a connected state of the loading disks. At least one of the end faces of at least one of the loading disks forms a spacer dome. In the connected state, the spacer dome contacts an end face of the other loading disk in order to position the first and the second loading disks with respect to each other in an axial direction.

Claims

1. An additional weight for a wheel for ballasting a drive axle of an agricultural working machine, comprising:

a first loading disk centrally connected to the drive axle, where the drive axle acts as an adapter element; and

at least one second loading disk connected to the first loading disk;

wherein, the first loading disk has a conical abutment face for pre-positioning the second loading disk relative to the first loading disk; and

wherein, the first and the second loading disks form encoding formations for mutually centering on end faces which face each other and which are in engagement with each other in a connected state of the loading disks, and the encoding formations in the end faces form a triangular shape;

wherein, at least one of the end faces of at least one of the loading disks forms a spacer dome, where in the connected state the spacer dome contacts an end face of the other loading disk in order to position the first and the second loading disks with respect to each other in an axial direction.

2. The additional weight of claim 1, wherein the first and second loading disks form on at least one of the end faces spacer domes via which the loading disks contact each other in the connected state.

3. The additional weight of claim 1, wherein the encoding formations are constructed partially as recesses and partially as protrusions.

4. The additional weight of claim 1, wherein a through-hole extends through the spacer domes.

5. The additional weight of claim 1, wherein the first loading disk has a securing hole circle for securing to a wheel flange of the drive axle.
