Abstract
A wearing part, preferably for a vehicle, contains a wear indicator whose appearance changes depending on a wear condition of the wearing part. The wear indicator contains a multidimensional pattern that is disposed on the wearing part such that different levels of the pattern are exposed depending on the wear condition.
Claims16
A wearing part, comprising:
- a tire having a tread and formed of a tire material;
- a wear indicator incorporated in said tread of said tire and whose appearance changes depending on a wear condition of said tire, said wear indicator having a multidimensional pattern that is disposed on said tire such that different levels of said multidimensional pattern are exposed depending on the wear condition, said different levels of said multidimensional pattern each represent a 2D code, said 2D code having black areas formed by said tire material and an intermediate space between said black areas of the 2D code is implemented as a pocket;
- and
- said wear indicator is retrospectively introduced as a separately manufactured component into said pocket.

A wearing part, comprising:
- a brake disk having a friction surface and formed of a brake disk material;
- a wear indicator incorporated in said brake disk and whose appearance changes depending on a wear condition of said brake disk, said wear indicator having a multidimensional pattern that is disposed on said friction surdace such that different levels of said multidimensional pattern are exposed depending on the wear condition, said different levels of said multidimensional pattern each represent a 2D code, said 2D code having areas formed by said brake disk material and an intermediate space between said areas of the 2D code is implemented as a pocket;
- and
- said wear indicator is retrospectively introduced as a separately manufactured component into said pocket.

A wearing part, comprising:
- a tire having a tread and formed from a tire material;
- a wear indicator incorporated in said tread of said tire and whose appearance changes depending on a wear condition of said tire, said wear indicator having a multidimensional pattern that is disposed on said tire such that different levels of said multidimensional pattern are exposed depending on the wear condition, said different levels of said multidimensional pattern each represent a 1D code, said 1D code having black bars formed by said tire material and an intermediate space between said black bars of said 1D code is implemented as a pocket;
- and
- said wear indicator is retrospectively introduced as a separately manufactured component into said pocket.
