Sensing device for rotation rate and/or direction

摘要

In order to be able to attach a rotational-speed or direction-of-rotation transmitter, in particular in the form of a rotor (3), to the circumference of a rotor shaft (2) in a simple and reliable fashion, the rotational-speed or direction-of-rotation transmitter is connected indirectly to the rotor shaft (2) by means of at least one separate, radially resilient or elastic intermediate securing part. Preferably, at least one rubber ring (4 or 5) is provided as the intermediate securing part and is clamped onto the rotor shaft (2) or pressed into a shaft orifice of the rotor (3) expediently before final assembly, to provide a premounted unit.
