Patent number: 8862344Abstract: A clutch actuator and to a method for the control thereof. The actuator actuates a multi-disk clutch, and to do so has actuator modules. The number of which corresponds to the number of the friction clutches. The modules have separate control units and electric motors, which are controlled by the control units and act on the friction clutches by a disengaging mechanism. In order to counter block the partial drive trains disposed downstream of the friction clutches, particularly automatically closed friction clutches during a malfunction of an actuator module, the actuator modules are connected among each other to a data line, which allows monitoring of the actuator modules and counter-measures.Type: GrantFiled: July 1, 2010Date of Patent: October 14, 2014Assignee: Schaeffler Technologies AG & Co.

Publication number: 20140283646Abstract: A transmission system for a hybrid vehicle is disclosed. The system includes a primary input shaft for receiving drive from a primary vehicle drive motor, such as an internal combustion engine. A secondary input shaft receives drive from a secondary vehicle drive motor, such as an electric motor. An output shaft of the system is connected to drive a final drive unit. A multi-speed gearbox is provided to connect the primary input shaft to the output shaft at one of a plurality of gear ratios. There is provided an input selection mechanism which, in a first configuration, connects the secondary input shaft to drive the output shaft and, in a second mode, connects the secondary input shaft to drive the primary input shaft. A clutch may be provided that can selectively connect or disconnect drive between the primary drive motor and the gearbox.Type: ApplicationFiled: July 11, 2012Publication date: September 25, 2014Inventors: Adrian Paul Moore, Clive David Woolmer, Christopher Guy Cholmeley, Michael John Allen, Matthew Charles Clutterbuck, Paul Pomfret

Publication number: 20140245861Abstract: A manual transmission including an input shaft Ai to which power is input from an internal combustion engine E/G through a clutch C/T and an output shaft Ao from which power is output to drive wheels. This transmission has a plurality of EV travel gear stages (different from the neutral) in which no power transmission system is established between the input shaft Ai and the output shaft Ao, and a plurality of HV travel gear stages in which a power transmission system is established between the input shaft Ai and the output shaft Ao. This transmission has a connection changeover mechanism which establishes and breaks connection between the output shaft of the electric motor and the output shaft. When an EV travel gear stage is selected, a “connected state” is always realized. When an HV travel gear stage is selected, a “disconnected state” is realized in some cases.Type: ApplicationFiled: July 11, 2012Publication date: September 4, 2014Applicant: AISIN AI CO., LTD.Inventor: Yuuki Masui
