Patent number: 10443722Abstract: A device and method for preventing inadvertent selection of a parking lock function in a 2-ratio transmission. Here, the shift positions of the transmission and the parking lock function thereof can be selected by way of a shift drum. A mechanically acting apparatus is provided which, in the event of rotation of the shift drum in a first direction of rotation, blocks the selection of a parking lock position of the shift drum, subsequently, in the event of rotation of the shift drum in a second direction of rotation opposite to the first direction of rotation, releases the blocking, and subsequently, in the first direction of rotation opposite to the second direction of rotation, permits selection of the parking lock position. The device does not require a separate parking lock wheel.Type: GrantFiled: December 14, 2016Date of Patent: October 15, 2019Assignee: Dr. Ing. h.c. F. Porsche AktiengesellschaftInventors: Joachim Esser, Hans-Jürgen Renk

Patent number: 8157704Abstract: A method controls a drivetrain of a motor vehicle having an internal combustion engine, an automatic transmission with at least two discrete transmission stages, and a clutch which is controlled automatically. The method is characterized in that when there is a transmission output speed at which the transmission input speed in an n-th transmission stage would be above a minimum rotational speed of the internal combustion engine and a transmission input speed in an (n+1)-th transmission stage would be below the minimum rotational speed, the drivetrain is operated in the (n+1)-th transmission stage with a slipping clutch and a rotational speed of the internal combustion engine which is above the minimum rotational speed. A control unit is configured to carry out such a method.Type: GrantFiled: May 11, 2009Date of Patent: April 17, 2012Assignee: Dr. Ing. h.c. F. Porsche AkteingesellschaftInventor: Joachim Esser

Patent number: 8104595Abstract: A hydraulic control unit is set up to hydraulically actuate a starting clutch of a motor vehicle and gear selectors of a transmission of the motor vehicle by use of hydraulic valves which are integrated in the hydraulic control unit and which have in each case at least one control element. The hydraulic control unit is characterized in that the integrated hydraulic valves are aligned in the hydraulic control unit in such a way that a movement direction of a vibratory element of a hydraulic valve which controls only the starting clutch differs from the movement direction of vibratory elements of the other hydraulic valves, and is aligned to a lesser extent with the longitudinal axis of the motor vehicle.Type: GrantFiled: December 22, 2008Date of Patent: January 31, 2012Assignee: Dr. Ing. h.c. F. Porsche AGInventors: Frank Kurrle, Joachim Esser, Jan Pfingst, Arne Krüger, Thorsten Böger

Publication number: 20100156059Abstract: The present disclosure relates to a transporting device for transporting loads by hand with a base frame made of sheet metal or metal tubing in the manner of a hand truck, which has two transport wheels at a lower end opposite a loading shovel and in the center of the lower end, a support wheel in a first end position. The support wheel can be displaced along the longitudinal extension of the base frame into a second end position.Type: ApplicationFiled: December 22, 2009Publication date: June 24, 2010Applicant: PracTec GmbHInventor: Joachim Esser

Patent number: 7704189Abstract: A method implements a starting process for an internal combustion engine which has a drive unit and a transmission with at least two transmission input shafts and a multiple clutch device, in particular a double clutch device. During the starting process, the first gear is engaged in a first clutch of the multiple clutch device and is activated, while the second gear speed is engaged in a second clutch of the multiple clutch device but not activated. During the starting process, a current velocity is compared with a predefinable reference velocity, and when the reference velocity is reached a control unit causes the first clutch to be opened and thus causes the first gear to be deactivated while, in parallel with this, the second clutch is closed and the second gear is thus activated.Type: GrantFiled: April 30, 2007Date of Patent: April 27, 2010Assignee: Dr. Ing. h.c. F. Porsche AGInventors: Peter Baur, Joachim Esser, Christian Hauck, Dieter Kraxner

Publication number: 20090188767Abstract: A hydraulic system for a clutch has a pump conveying a hydraulic fluid stream via a heat exchanger to a controllable hydraulic valve which divides the hydraulic fluid stream into a first part stream and a second part stream. The first part stream flows to a reservoir via friction linings of the clutch and the second part stream flows to the reservoir via a hydraulic path bypassing the friction linings. The hydraulic system is set up for upgrading a cooling of the clutch by increasing the first part stream at the expense of the second part stream and for reducing the cooling of the clutch by increasing the second part stream. The system is set up for temporarily upgrading the cooling of the clutch in the event of a changeover of torque transfer from transfer via a first part transmission to transfer via a second part transmission of the transmission.Type: ApplicationFiled: January 26, 2009Publication date: July 30, 2009Applicant: DR.
