contamination of the sensor or of the contact sites of the sensor or of a magnet assigned to the sensor by the lubricating grease of the worm gear, a partition is provided there, which divides the accommodating space into a section, which accommodates the coil spring, and a section, which accommodates the transmission. The housing of the coil spring forms a part of this partition.
The DE-A1 197 55 094 also discloses such an electromechanical steering system.
The coil spring housing with the coil spring disposed therein is located in an accommodating space within a steering housing, in which the steering shaft is mounted rotatably. The worm gear, which transfers the rotational movement of the electric motor to the steering shaft for supporting the steering movement, is located in theaccommodating space in the steering housing. It is necessary to pay attention so that the sensor or the contact sites of the sensor or a magnet, assigned to the sensor, are not contaminated by the lubricating grease of the worm gear. In addition, the coil springs, including the coil spring housing and the steering angle sensor, also represent a source of danger for the worm gear, since the latter can be blocked in the event that a component within the accommodating space becomes detached or breaks off.
