Patent number: 10995856Abstract: In a parking lock for an automatic transmission, an electrical parking lock actuator has an electric motor, a spur gear stage driveable by the electric motor, and a worm gear stage driveable by the spur gear stage. A worm shaft of the worm gear stage is connected rotationally conjointly to an output gear of the spur gear stage, and a worm gear of the worm gear stage is connected rotationally conjointly to a transmission-side parking lock shaft. The worm shaft is fixed in an axially displaceable manner in the output gear. A stop limits the pivoting movement of the worm gear when a parking lock position of the parking lock shaft is reached. A spring braces the worm shaft in an axial direction of the worm shaft against a holding mechanism which is situated in a stop position, in which the holding mechanism is fixed by an electrically energized electromagnet.Type: GrantFiled: February 6, 2020Date of Patent: May 4, 2021Inventors: Klaus Gausrab, Arne Krüger

Patent number: 10612602Abstract: A spring-actuable friction clutch, having a disk carrier and a cup spring which is connected to the latter via screwed connections. Threaded sleeves are arranged fixedly on the disk carrier. The cup spring has openings which are penetrated by the threaded sleeves. A holding ring is arranged on that side of the cup spring which faces away from the disk carrier. Bolts penetrate passages of the holding ring and are screwed into the threaded sleeves. In a friction clutch of this type, particularly simple mounting and fastening of the cup spring on the disk carrier is ensured.Type: GrantFiled: February 6, 2018Date of Patent: April 7, 2020Assignee: Dr. Ing. h.c.

Patent number: 10358145Abstract: An actuating device for shifting stages of a transmission, wherein a displaceable actuator for the manual selection of a shift stage (or driving mode) is provided, which can be adjusted into a plurality of positions. At least some or each of the positions can be assigned necessary conditions for the engagement of a shift stage assigned to the position. If the actuator is displaced into a position for which the conditions necessary for the same are not fulfilled, the associated shift stage is not engaged in the transmission and corresponding first signaling is carried out. Fulfillment of the necessary conditions of the associated shift stage following the displacement of the actuator into the position assigned to the shift stage or following the displacement in the direction of the associated position for the associated shift stage leads to the shift stage in the transmission being engaged.Type: GrantFiled: September 21, 2017Date of Patent: July 23, 2019Assignee: Dr. Ing. h.c.

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.

Patent number: 8074779Abstract: A clutch system has a clutch device, an actuating device for the hydraulic actuation of the clutch device, and a hydraulic system. The hydraulic system includes a master cylinder that is actuated by the actuating device, a slave cylinder for actuating the clutch device fluidically connected with the master cylinder through a pressure line. A first branch line is connected to the pressure space of the master cylinder or between the pressure spaces of the master cylinder and slave cylinder. The first branch line is also connected to a compensating tank volume. A second branch line is connected to the pressure space of the slave cylinder or arranged between the pressure spaces of the master and slave cylinders. The second branch line is also connected to the compensating tank volume. A device is disposed to blocking the second branch line during an actuation of the clutch device by way of the actuating device. This provides for an inherently safe, self-ventilating hydraulic system.Type: GrantFiled: July 10, 2008Date of Patent: December 13, 2011Assignee: Dr. Ing. h.c. F.
