Publication number: 20010030099Abstract: The friction clutch comprises a clutch disk arrangement which can be brought into frictional engagement with associated friction surfaces by the action of a movably mounted thrust plate arrangement. The actuation device includes a pressure medium force cylinder arrangement by means of which the friction clutch can be actuated by an actuating member; a measuring arrangement detects an actual actuation. A control/regulating valve arrangement is connected with a pressure medium source, with a pressure compensation opening or a pressure compensation reservoir and with the pressure medium force cylinder arrangement, by means of which control/regulating valve arrangement the pressure medium force cylinder arrangement can be actuated depending on the actual actuation and on a reference actuation which can be predetermined. According to one aspect of the invention the measuring arrangement detects an adjusting path of at least one thrust plate of the thrust plate arrangement as actual actuation.Type: ApplicationFiled: March 19, 2001Publication date: October 18, 2001Applicant: Mannesmann Sachs AGInventor: Hans Fliege

Patent number: 5915488Abstract: The components of a vehicle, in particular of a non-rail vehicle, which is powered by an electric motor traction propulsion system, can be protected against the damaging effects of accelerations which occur during operation by reducing the operating power supplied to a propulsion motor of the vehicle when the accelerations which occur on certain components of the vehicle reach values which pose an immediate danger to these components or reduce their useful life.Type: GrantFiled: January 26, 1996Date of Patent: June 29, 1999Assignee: Fichtel & Sachs AGInventor: Hans Fliege

Patent number: 5678646Abstract: A propulsion system for a vehicle comprising an electric motor, circuit breakers which switch field windings of the electric motor, as well as a cooling device which cools the field windings and the circuit breakers by its coolant circuit. The electric motor is realized in the form of a first modular unit which is mechanically functional in itself. The circuit breakers are assembled in at least one second modular unit, which is connected firmly to the first modular unit to form a propulsion unit. The individual modular units can be separated from one another and are connected to one another both by detachable electrical interface connections and also by detachable coolant interface connections. This construction makes it possible to selectively expand the propulsion unit by adding additional modular units, or in the event of the failure or malfunction of individual modular units to replace the modular units without having to replace the entire propulsion unit.Type: GrantFiled: December 1, 1995Date of Patent: October 21, 1997Assignee: Fichtel & Sachs AGInventor: Hans Fliege

Patent number: 5675222Abstract: An electric road motor vehicle with a switchable winding electric motor propulsion system, a switchable winding electric motor propulsion system in an electric road motor vehicle, and a switchable winding electric motor propulsion system for a motor vehicle. For the optimization of an electric motor propulsion system of a vehicle, the electric motor equipped with a rotary field winding is connected through a switching system to an electronic converter, so that due to the switching system, the number of phase windings of the rotary field winding to be connected to the individual output connections can be changed. The switching system is controlled by a control circuit through a actuator. The control circuit also controls the converter and deactivates the driver currents fed to the rotary field winding, while it switches over the switching system through the actuator. The switching system can thereby be made simpler and smaller.Type: GrantFiled: September 1, 1995Date of Patent: October 7, 1997Assignee: Fichtel & Sachs AGInventor: Hans Fliege

Patent number: 4734693Abstract: For controlling a central locking installation and/or theft alarm of a motor vehicle a switch lock installation is provided which comprises at least one lock with mechanical tumblers for the mechanical locking and unlocking of a door or a bonnet of the motor vehicle. The tumblers form a first key secret. The key which blocks the tumblers carries an electrically, magnetically or optically readable information carrier for a second, operationally variable key secret. A reading device detects the information of the second key secret in a position in which the mechanical tumblers of the lock are released. If the key is moved in the opening direction of the lock, a control circuit compares the information read by the reading device with an ideal information stored in a memory circuit and controls the central locking installation and/or theft alarm accordingly.Type: GrantFiled: July 18, 1985Date of Patent: March 29, 1988Assignee: Sachs-Systemtechnik GmbHInventors: Joachim Dluhosch, Hans Fliege, Dieter Lutz, Franz Nagler, Horst Oppitz, Christoph Thielen, Wolfgang Thieler

Patent number: 4562711Abstract: The locking system comprises a magnetic key having a plurality of parallel rows of magnets arranged in a pattern one behind the other and forming a locking code of the magnetic key, and a reading device into which the magnetic key can be inserted in the direction of the rows of its magnets. The reading device comprises magnetic field sensors for the serial reading of the locking code formed by the magnets. A control circuit which compares the information of the read locking code with the information of a predetermined locking code generates a control signal in dependence upon the conformity or difference of the locking codes. At least the magnets of the pattern positions of each row which are immediately adjacent in the row direction are oppositely polarized.Type: GrantFiled: May 17, 1984Date of Patent: January 7, 1986Assignee: SACHS-Systemtechnik GmbHInventor: Hans Fliege

Patent number: 4280118Abstract: An operating mechanism for a lock and the like is operated by means of a key on which permanent magnets may be secured in available magnet positions of a fixed pattern of such positions, selected positions being occupied by magnets. A reading device includes a reader body and a guide for guiding the key into a predetermined position in which respective sensors are contiguously adjacent each available magnet position and respond to the presence of a magnet in the adjacent position by generating an electrical signal. The several signals are compared with a reference signal, and an operating signal is generated by a comparator connected to the sensors and to the source of the reference signal when the sensor signals agree with the reference signal.Type: GrantFiled: December 14, 1979Date of Patent: July 21, 1981Assignee: Sachs-Systemtechnik GmbHInventors: Gerd Brunken, Volker Eibl, Hans Fliege
