A fastening system configured for fastening a device to a hollow component having two holes situated opposite one another. The fastening system includes a first screw that has a head and that is designed to be guided through a first hole of the holes, and a sliding sleeve having an outer diameter that has a tolerance. The sliding sleeve is designed to accept the first screw at the second hole of the holes. An outer diameter of the sliding sleeve is displaceable in the axial direction of the first screw due to a clearance fit.

Fastening arrangement, in particular for fastening an electric drive to an electric bicycle

A method for ascertaining a state of an electric drive of a transportation device, in particular a bicycle. The method includes: providing sensor data from sensors of the drive, the sensor data indicating parameters of the drive if an instantaneous operating range of the drive and/or of the transportation device corresponds to a predefined operating range; storing such sensor data, as measuring sensor signals, which originate from sensors predefined for the predefined operating range; and recognizing a defect of the drive if at least one of the measuring sensor signals deviates from a predefined standard sensor signal by a predefined degree; as well as outputting a warning about the presence of the defect to a user of the transportation device.

Method for ascertaining a state of an electric drive of a means of transportation

A sensor for at least detecting steering torque of a steel steering column includes a magnetic field generating element which is configured to generate a magnetic field. The magnetic field penetrates the steering column so as to magnetize a steel material thereof. The sensor also includes a magnetic field detection element which is configured to detect a magnetic field change caused by a magnetoelastic effect of the magnetized steel material of the steering column when the steering column is subjected to torque stress. An output signal of the magnetic field detection element characterizes steering torque. The sensor also includes a base plate bearing the magnetic field generating element and the magnetic field detection element. The base plate is spaced from and separate from the steel steering column. The magnetic field generating element and the magnetic field detection element are directly mounted on the base plate.

Integrated torque and angle sensor for steering column monitoring with improved performance

A torque detection unit for actively detecting a torque acting on a shaft, and in particular on a crankshaft, of a vehicle drivable by muscle power and/or by motor power along a rotational axis, including an excitation unit, which is configured to apply a magnetic field which changes over time to the shaft, and a first sensor unit and a second sensor unit, which are configured to detect a magnetic field carried by the shaft, the first and the second sensor unit, in particular with an otherwise identical setup, having different orientations with respect to one another so that they, during operation, are oriented differently from one another with respect to the shaft, and in particular with respect to the rotational axis.
