Pulse transducer for detecting vehicle wheel revolution rate - has pulse ring with uniformly distributed apertures bounded by angled struts, and rotating counter piece on outer surface

摘要

The pulse transducer consists of a ring (5) with uniformly spaced apertures in the central region and bounded by struts. The ring is pressed onto the outer surface (3) of a rotating counter piece. The struts (6) are angled away from the sensor (9) in the region of a radially offset lateral edge (8). The pulse ring rests on the outer surface of the attachment parts, which can also be angled, with all of its inner surface sections. The angled region (6") of the pulse ring extends over about one third of its total width. ADVANTAGE - Exact measurement of revolution rate of motor vehicle wheel using simple design.
