Patent number: 5674155Abstract: A method of operating a torque transmitting system with a hydrodynamic power transmission and with a friction clutch, which constitutes a lock-up clutch and bridges the power transmission, involves controlling the lock-up clutch and the hydrodynamic power transmission so that clutch slip is present. The input torque furnished by a prime mover is divided into a torque which is to be transmitted by the power transmission and a torque which is to be transmitted by the lock-up clutch. The lock-up clutch includes an annular piston which is disposed between the cover and the turbine wheel of the power transmission. The radially outer portion of the piston constitutes a clutch disc and its radially inner portion is mounted on a complementary sealing hub. The power transmission is "soft" and exhibits a flat progress of the primary characteristic curve as well as a wide secondary characteristic curve, i.e., a wide torque conversion range.Type: GrantFiled: October 17, 1994Date of Patent: October 7, 1997Assignee: LuK Gebriebe-Systeme GmbHInventors: Dieter Otto, Thomas Pfund, Klaus Herzog, Anton Rink

Patent number: 5643004Abstract: A connection contact in a single piece has two insulation displacement contacts (14) having each an insulation displacement slot (16), a contact and guiding surface (20) and a shearing element. The connection contact further has two contact legs (22, 23) one end of which is connected to an insulation displacement contact (14), a home contact formed between the free ends of the contact legs and a section (27) that links the insulation displacement contacts (14). The disclosed connection contact in a single piece is characterized in that the linking section (27) is designed as a substantially U-shaped loop (28). As lead-shearing element, an insulation displacement contact (14) is associated to each leg (30) of the U- or V-shaped loop (28), so that the contact pressure between the contact legs of the home contact can be easily adjusted as desired. A fatigue-proof home contact is thus obtained, which is also economical to produce.Type: GrantFiled: August 14, 1996Date of Patent: July 1, 1997Assignee: Quante AktiengesellschaftInventors: Hans-Dieter Otto, Thomas Wabnitz, Ralf Korte

Patent number: 4850814Abstract: A hydraulic gear pump for the oil lubrication system of an automobile engine is disclosed, and wherein the meshing teeth of the gears define fluid cells which are expanded in the intake portion and receive the fluid from an inlet, and then compressed in the discharge portion to expel the fluid. The inlet to the pump includes at least two parallel fluid lines which are each connected to a tank. A pressure controlled valve is connected to one or both of the fluid lines, and during the normal operating range of output pressure, the valve is controlled by the pressure in the pump discharge chamber so as to decrease the flow through the lines from a maximum flow rate to a lower flow rate as the output pressure increases. In the event the engine and oil are cold, the output pressure will increase beyond the normal operating range, since the oil consumption is small.Type: GrantFiled: November 9, 1987Date of Patent: July 25, 1989Assignee: Barmag AGInventors: Siegfried Hertell, Dieter Otto

Patent number: 4499757Abstract: An element firmly connected with the drive shaft of an injection pump is locked in a predetermined rotary position, corresponding to the supply onset, by a locking device before the mounting of the injection pump to the associated internal combustion engine, the locking being effected by means of a holding bolt embodied as a reversible part. The holding bolt, locked by a fastening means in a reception bore, engages a transverse groove on the end face, in a first mounting position, via a protrusion on the element firmly connected with the drive shaft, and thus establishes a form-locking connection which keeps the drive shaft in the predetermined rotary position. In a second mounting position of the holding bolt, where the transverse groove points outward, the rotary movement of the drive shaft is unhindered.Type: GrantFiled: November 1, 1982Date of Patent: February 19, 1985Inventors: Egbert Backe, Rolf Muller, Dieter Otto, Cornelio Leonardi, Heinrich Kochendorfer, Paul Fussner, Ewald Walker, Rudi Rommel
