Patent number: 7574296Abstract: A process and device for the currentless referencing of a clutch position in non self-locking clutch actuating systems which are switched without current for a first predetermined, passive period of time or until an actuator standstill occurs, in order to verify a clutch reference position, then the clutch position achieved is determined by first measurement and current is supplied to the clutch actuating system for a predetermined, active period of time, the clutch actuating system being then switched again without current for another predetermined, passive period of time or until an actuator standstill occurs, the clutch position being determined by another measurement; finally the measured clutch position is checked to determine whether it can be verified as a new clutch reference position.Type: GrantFiled: December 21, 2007Date of Patent: August 11, 2009Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Markus Baehr, Felix Dreher, Matthias Panzer, Frank Stengel, Martin Fuss, Jens Martin, Martin Zimmermann, Matthias Ehrlich, Alexander Schweizer

Publication number: 20080295628Abstract: A method for adjusting the gearbox actuation system of an automatic gearbox of a vehicle, whereby at least one reference travel is made with the gear engaged. The invention further relates to a gearbox actuation system for selecting and engaging gears in an automatic gearbox of a vehicle, especially for carrying out the inventive method, whereby at least one reference travel is made for the purpose of adjustment.Type: ApplicationFiled: August 5, 2008Publication date: December 4, 2008Applicant: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Klaus Kupper, Klaus Henneberger, Jorg Metzger, Reinhard Berger, Frank Stengel

Patent number: 7448291Abstract: To improve the safety of automated gearboxes, it is proposed that terminal positions of internal gearshift members and external actuation members be so defined separately from each other that one can recognize whether the engagement of a speed is accompanied by the attainment of a terminal position of an internal gearshift member or an external actuation member. Error analysis is possible in this way. For dual clutch gears, it is additionally proposed that one can, at least in gearshift operations that are critical in terms of safety, disengage on speed of a subgear in a separate procedure, before a new speed of this subgear can be engaged.Type: GrantFiled: August 31, 2005Date of Patent: November 11, 2008Assignee: LuK Lamellen und Kupplungsbau Beteiligungs KGInventors: Frank Stengel, Alexander Schweizer, Martin Zimmermann, Behzad Nazari, Joachim Hirt, Martin Fuss, Matthias Ehrlich, Jens Martin

Patent number: 7417401Abstract: A method for operating a drive mechanism comprising bringing a mobile element into a predetermined reference position with the help of an engine and setting an absolute position signal to a reference value allocated to a reference position; changing the position of the mobile element with the help of the engine and creating an incremental position measurement signal, depending on the change in position, for the mobile element; controlling the incremental position measurement signal and following the absolute position signal when a change in the incremental position measurement signal occurs; repositioning the mobile element in the reference position with assistance of the engine and determining the position value indicated by the absolute position signal in the reference position; determining a difference value from the position value and the reference value and saving the difference value in a data storage; and, repeating steps b) through e) are performed at least once.Type: GrantFiled: September 29, 2006Date of Patent: August 26, 2008Assignee: Luk Lamellen und Kupplungsbau Beteiligungs KGInventors: Alexander Schweizer, Martin Zimmerman, Jens Martin, Joachim Hirt, Martin Fuss, Matthias Ehrlich, Frank Stengel

Patent number: 7402036Abstract: A nozzle contact device for guiding and clamping the injection nozzle for an injection unit of an injection molding machine onto an injection mold includes a linear drive for moving the injection unit back and forth, and a guide carriage which can be driven by the linear drive, with the guide carriage being articulated to the injection unit. The invention is characterized in that the axis of rotation of the articulation between the guide carriage and the injection unit extends horizontally, and that this axis of rotation and the injection axis are arranged on planes which are parallel to each other, preferably on the same horizontal plane. Rotary joints or flexural joints can be provided. In addition, the rear part of the injection unit, in particular a screw mechanism can be height-adjustable. As a result, the nozzle contact force is introduced into the injection unit in the absence of a bending moment. No tilting is caused between the injection nozzle and the sprue bush of the injection mold.Type: GrantFiled: February 13, 2006Date of Patent: July 22, 2008Assignee: Demag Ergotech GmbHInventors: Holger Schmidt, Donald Meinert, Frank Stengel
