A sensor ring is provided for a magnetic measuring transducer of an ABS system consisting of at least two annularly arranged functional elements. The first functional element is formed as a ferromagnetic annular disc element with a flat upper side and a flat underside with a multiplicity of openings. The second functional element, as a non-ferromagnetic element, has either been applied on the upper side and/or the underside of the annular disc element and/or has been introduced into the openings, as an annular disc element. The sensor ring is protected from contamination or damage by the non-ferromagnetic covering. The covering may also be produced by encapsulation or filling, wherein the openings in the sensor ring can be filled with plastic and also the side faces can be coated with plastic.

Sensor ring

An integral brake system for motorcycles, in which a hydraulic brake system acts on one wheel is connected by a hydraulic line to a main brake cylinder which is controllable with a first brake lever, a brake system acts on the other wheel, with an actuator controllable by both the first brake lever and a second brake lever, and an electronic control unit that contains a regulating device for controlled distribution of the brake force between the two wheels. The electronic control unit is connected by electric control lines to a sensor that responds to operation of the hydraulic brake system, to the actuator and to the second brake lever. The control unit controls the actuator as a function of the output signal of the sensor or, in the event of operation of the second brake lever, to activate the brake system that acts on the second wheel.
