Embodiment Construction

[0015] figure 1 The illustrated rim 1 of a vehicle wheel, not shown in its entirety, is made of sheet steel and is connected to a wheel disk 2 , for example by welding. The rim 1 has a rim base 1a. A brake disc 3 that rotates with the wheel and a brake caliper 4 that is stationary relative to the vehicle wheel are arranged in the overall space of the wheel disc 2 below the rim base 1a.

[0016] The rim 1 is made of a flat steel lath 5 in the middle of which is provided a row of markings 6a, 6b, 6c as markings 6 which are pressed into the flat as reinforcing grooves. of steel slats. The markings 6a, 6b, 6c form a repeating triplet of grooves of different widths with equal average distances. One such flat steel lath can be manufactured continuously. A corresponding length of part can then be cut therefrom to form a wheel rim 1 .

[0017] In the installed state of the vehicle wheel, a multi-set marking 6 with its markings 6 a , 6 b , 6 c is situated opposite a sensor 7 carri...

Abstract

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.

Description

technical field [0001] The invention relates to a rim for a vehicle wheel having a rim base, wherein a marking extending in the circumferential direction of the rim base is provided on or integrally in the rim base for The rotational speed is detected contactlessly when passing a sensor of a measuring device which is to be arranged spatially close to the vehicle wheel and which is stationary relative to the rotational movement of the vehicle wheel. Background technique [0002] Monitoring systems for monitoring the rotational speed of the wheels are part of the standard equipment of modern vehicles equipped with wheels, in particular those of vehicles for people. Among these systems, ABS (Antilock Braking System) is the most famous. One of the functions of these or other systems is to accurately detect the rotational speed of the wheels during a revolution. In order to detect the rotational speed as sensitively as possible, a measuring device for detecting the rotational s...
