摘要

#CMT# #/CMT# The drive system comprises a stator (10a), a rotor (11a), and a sensor for measuring the parameter such as mechanical stress on the wheel hub drive of vehicle, a safety device for the output of warning signal, and a control device. The control device triggers the safety device to output warning signal or to store the sensor measured parameters. The safety device outputs a warning to the user of vehicle and/or to a service unit and/or to the service personnel, when damage occurs in the wheel hub drive. #CMT# : #/CMT# Independent claims are included for the following: (1) a wheel hub drive; and (2) operating method of wheel hub drive in vehicle. #CMT#USE : #/CMT# Drive system of wheel hub drive in vehicle e.g. electrical and/or hybrid vehicle (all claimed). #CMT#ADVANTAGE : #/CMT# The performance of wheel hub drive is improved, and damage to the wheel hub drive can be detected early. The setting of propulsion system can be optimized for the determination of wear portions in the drive. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawings show the schematic cross-sectional views of the wheel hub drive in normal operation and during mechanical overloading process. 10a : Stator 11a : Rotor 20 : Rotation axis 21 : Roller 22 : Rim.
