ABSTRACT:
An L-shaped scanning ring, which is constructed as a simple stamped metal part, can be mounted at a crankshaft web of a crankshaft after installation of the crankshaft. The scanning ring rests against the crankshaft web with both legs and, on one of the legs, carries a toothing which inductively cooperates with a stationary sensor mounted in the crankcase. The ring has a radially extending gap and, as a result, can be bent open so far that it can easily be fitted over the crankshaft. As a result of the subsequent bending-together, the scanning ring rests form-fittingly against the crankshaft web and is protected from twisting by means of pins.
