Patent number: 6857334Abstract: The invention relates to a motor vehicle having a power train wherein the engine can drive an automatic transmission by way of an automatic clutch. The gear ratio of the transmission is selectable by a first drive and a second drive is employed to shift the transmission into the selected gear. The two drives are mounted on the transmission case by way of a common base plate. Novel kinematic transmission lines connect the drives to the ratio selecting and gear shifting components of the transmission. One of the transmission lines employs a transmission stage, a carrier for translation of rotary movement into axial movement, and an element for transfer of axial movement to the transmission. The translation of movement of the drive in a selection process takes place by way of two transmission stages.Type: GrantFiled: September 24, 2002Date of Patent: February 22, 2005Assignee: LUK Lamellen-und Kupplungsbau Beteiligungs KGInventors: Norbert Esly, Volker Kretz-Busch, Detlef Noack, Martin Meunier

Patent number: 5954178Abstract: A control unit for a friction clutch or another torque transmitting system and/or for a transmission system in a motor vehicle employs an actor having an electric motor arranged to drive a single-stage or multi-stage transmission which, in turn, transmits motion to one or more mobile parts of the torque transmitting and/or transmission system by way of one or more output elements of the actor. The motor receives signals from one or more sensors and/or from the electronic circuitry in the vehicle and/or from a memory. At least one coil spring and/or another energy storing element is or can be provided to guarantee that the torque transmitting system assumes a predetermined (e.g., disengaged) condition and/or that the transmission system is in a predetermined gear ratio when the actor is not in use to change the magnitude of torque being (or to be) transmitted by the torque transmitting system and/or the ratio of the transmission system.Type: GrantFiled: January 31, 1997Date of Patent: September 21, 1999Assignee: LuK Getriebe-Systeme GmbHInventors: Robert Fischer, Norbert Esly, Reinhard Berger, Karl-Ludwig Kimmig

Patent number: 5950780Abstract: The power train of a motor vehicle employs an automated transmission and an automated clutch between the transmission and the combustion engine. The clutch is automatically disengaged prior to, and is automatically reengaged after, each selection of a particular gear of the transmission. A common first actuator (such as a reversible stepping motor) is employed to select the condition of the clutch and to select various gears, and a second actuator is used to effect actual shifting of the transmission into or from a selected gear. The connection between the first actuator and a clutch operating member comprises a reciprocable or rotary first cam, and the connection between the first actuator and a gear selecting member comprises a preferably rotary second cam which receives motion from the first cam.Type: GrantFiled: February 27, 1998Date of Patent: September 14, 1999Assignee: LuK Getriebe-Systeme GmbHInventors: Wolfgang Reik, Norbert Esly, Robert Fischer
