Patent number: 9513102Abstract: An angle sensor for determining a rotation angle of a rotatable body, such as a steering column in a motor vehicle, includes a gear wheel. The orientation of a magnetic field generated by the gearwheel is configured to be detected by a magnetic field sensor. The gear wheel is comprised of a magnetisable material, such as hard ferrite, into which a magnetization is introduced. The gear wheel is stronger in a central region than in an edge region in which the teeth are arranged. In order to weakly magnetize the edge region, which minimizes a negative influence of the teeth on the homogeneity of the generated magnetic field, the front face of the gear wheel is configured to be magnetized. The magnetization process advantageously takes place at the same time as an injection moulding process to form the gearwheel. A method is implemented to produce the gear wheel.Type: GrantFiled: October 10, 2011Date of Patent: December 6, 2016Assignee: Robert Bosch GmbHInventors: Alexander Braun, Wolfgang Welsch, Matthias Waibler, Klaus Burkhardt, Mathias Kimmerle

Patent number: 9030191Abstract: A sensor subassembly for a vehicle has at least one sensor unit arranged in a cap-shaped plastic part. The cap-shaped plastic part is carried by a retaining bush and seals off the retaining bush at one end. An associated device is configured to measure rotational movement of a wheel bearing. A resilient sealing and compensating element in pressed in between the-shaped plastic part and the retaining bush, in a first sealing area for sealing off a first leakage path, so that the cap-like plastic part, in conjunction with the sealing and compensating element, seals off the retaining bush tightly at one end.Type: GrantFiled: February 28, 2011Date of Patent: May 12, 2015Assignee: Robert Bosch GmbHInventors: Kenichi Ninomiya, Matthias Waibler, Anwar Hegazi, Andreas Fink, Mirko Scheer
