Publication number: 20070028446Abstract: A gear wheel includes multiple helical toothings, each having a different helical angle. A pressing method for molding a gear wheel involves introducing a compactable material into a chamber of a pressing tool, compacting the material, exposing the helical toothings of the gear wheel, and removing the molded body from the pressing tool. A pressing tool for pressing, as one part, a gear wheel, includes a matrix, cylindrical first and second molding tool parts which can be translated along and then rotated about a longitudinal axis, and a driver coupled to the molding tool parts or driving them. The molding tool parts can be moved towards and away from each other and the inner surface of the matrix delimits the chamber and is shaped to allow a linear axial sliding movement of the compactable material relative to the matrix.Type: ApplicationFiled: October 13, 2006Publication date: February 8, 2007Inventors: Manfred Arit, Gerhard Subek, Thomas Franz, Christian Reimann, Otto Stock, Anton Eiberger

Patent number: 7066049Abstract: The present invention relates to an accelerator pedal for a motor vehicle, especially one with an automatic gearbox. The pedal includes a pedal arm which in one end area thereof is pivotally mounted about a pivoting axis and which in the other end thereof is provided with a pedal plate which can be impinged upon the force by the driver. When force is exerted upon the pedal plate, the pedal arm can be pivoted into an absolute final position when a kick down switch is actuated, wherein a signal can be produced by the kick down switch and can be fed to a control electronics system. The kick down switch comprises a permanent magnet, the magnet force thereof being used to retain a magnetically conducting component on a magnetic return element whereby the component can be moved away from the magnetic return element as a result of the movement of the pedal arm into an end position.Type: GrantFiled: February 27, 2004Date of Patent: June 27, 2006Assignee: Siemens AGInventors: Christian Reimann, Christian Weis, Joachim von Willich

Patent number: 6960856Abstract: An electric motor is provided with rotor and stator. The stator includes stator poles radially facing the rotor and surrounded by stator windings. An insulating sleeve is positioned between the rotor and stator. The sleeve includes projections arranged radially with respect to the rotor. The projections project in a direction away from the sleeve and rotor and towards the stator. The projections project between adjacent stator poles and may further serve to anchor the poles. The projections may have a T or elongated T shape. The projections and sleeve are rigid and either or both may be made of plastic. The sleeve provides a moisture or liquid tight insulation for the stator so that the motor can be used in moist or liquid environments.Type: GrantFiled: June 13, 2003Date of Patent: November 1, 2005Assignee: Siemens AktiengesellschaftInventor: Christian Reimann

Publication number: 20050145058Abstract: The invention relates to a power control device for drive motors in motor vehicles, in particular an accelerator pedal, with an operating lever which may be operated by an operating force against a return force from a rest position on pivoting about a pivot axis. A damping device for damping the pivot motion of the operating lever is also provided. The damping device is a friction device which comprises a friction element, by means of which a component of the operating lever is acted upon such that in addition to the return force a friction force is also overcome during a pivot movement of the operating lever in a direction away from the rest position.Type: ApplicationFiled: December 30, 2004Publication date: July 7, 2005Inventors: Peter Kohlen, Christian Reimann, Joachim von Willich

Patent number: 6781275Abstract: A carbon brush spring system comprises a carbon brush arranged at a first terminal surface thereof conductively contacting a rotatable collector body (20) for electric current transfer. The system furthermore comprises a spring part arranged at a region of the carbon brush away from the first terminal surface to engage with the carbon brush for therewith establishing a current conductive interconnection to an external electric facility. The system furthermore comprises mechanical stabilizing arranged for maintaining a stable position of the carbon brush relative to the rotatable collector body in both radial and tangential directions in a housing. Particularly, the system has a substantially symmetric structure in tangential direction of rotation, through being provided with a first section (30,36) and a second section (29, 38) that collectively constitute the spring part. Furthermore, a carbon brush part (22, 24) is structurally fixed to the spring part.Type: GrantFiled: February 13, 2003Date of Patent: August 24, 2004Assignee: Siemens AktiengesellschaftInventors: Christian Reimann, Hans-Ulrich Vogler

Patent number: 3953696Abstract: An actuator comprises a housing having a bore with an opening and having a recess stop surface defined along the bore. A push button actuator is displaceable in the bore and projects through the opening so that it may be moved by hand between a non-actuated position to an actuated position. The push button includes a cross-bore or cavity with a lock bolt movable in the cavity and biased by a spring so that it engages with the stop surface when the push button is in a deactivated position. The housing also has a crossbore or recess containing a release member which has a push button end which is engageable from the exterior of the housing to displace the release member. In the locked deactivated position, the release member is engaged with the locking member so that the displacement thereof forces the locking member against its biasing spring to a position in which it is moved out of engagement with the stop surface so that the push button may be moved to an activated position.Type: GrantFiled: July 12, 1974Date of Patent: April 27, 1976Assignee: J. & J.
