Rail vehicle comprising means for monitoring the wheel-rail adhesion value

摘要

Generated by a drive unit (2), driving power is distributed with different intensity onto pairs of driven wheels (3a-3j). With a relatively more powerfully driven pair of wheels (3a,3b) there are the means for monitoring a wheel-rail coefficient of adhesion so as to identify a coating of grease (5) that is on a fixed rail (4) and impairing a braking system.
