One of the claws is movable relative to the blade holder and can be fixed in position by means of an adjusting unit. When the adjusting unit is loosened, then by pivoting of the blade holder about one of the two claws, which pivoting is made possible by a deflecting movement of the movable claw, the other claw is released from the associated profiled member and the blade holder is removable from the traverse.

Abstract: A method for determining the tread depth of a vehicle tire during driving includes the step of determining the angle of a radially outer tire location relative to hub-based a coordinate system based of the vehicle tire by a sensor fastened to the vehicle. A signal containing harmonic oscillation sent by the sensor is then analyzed and, based on the signal, the resonant frequency is determined corresponding to the torsional oscillation component of the tire belt relative to the wheel. The mass moment of inertia of the tire belt about the axis of rotation is then computed based on the torsional stiffness of the tire sidewall and the determined resonant frequency. The actual mass and changes of the tire diameter are then calculated based on the computed mass moment of inertia and based on a mass function of the vehicle tire that is a function of the tire diameter. The loss of tread depth is then calculated based on the changes of the tire diameter.
