| 摘要 |
The present invention relates to a wheel rim ( 1 ), having a wheel rim bed ( 1 a), of a vehicle wheel having a detection system for a measurement device for detecting the rotational velocity of the vehicle wheel. The detection system comprises a marking ( 6 ), running around the circumference on the wheel rim bed ( 1 a) or integrated therein, made of a track of marks ( 6 a, 6 b, 6 c), which are implemented as a profile that stiffens the wheel rim bed ( 1 a) and are detectable without contact to detect the rotational velocity when passing a sensor ( 7 ) of a measurement device to be positioned stationary next to the vehicle wheel.
