Gerd Jaeggle has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process for controlling a twin clutch
    Patent number: 8167774
    Abstract: A process for controlling a twin clutch transmission with two partial drive trains with respectively a friction clutch interposed between an internal combustion engine and the partial drive train is provided. If the transmission capacity of a friction clutch falls below the engine torque, engine intervention takes place. If the clutch temperature rises further above a default value, an emergency operation is initiated, in which the affected partial drive train is deactivated by opening the affected friction clutch, a preselection strategy used in the other partial drive train is changed and the other partial drive train is activated.

  • Method and system for detecting damage done to a clutch having at least two components that transfer torque by frictional engagement
    Patent number: 7603220
    Abstract: A method for detecting damage done to a clutch having at least two components that transfer torque by frictional engagement comprises the following steps: determining the friction power L introduced into the friction surfaces of the components by slippage between the torque-transferring components, calculating an individual damage value ESW=f(L,t), wherein t denotes time, and rating the clutch as damaged when ESW exceeds a predetermined value.

  • Method for adjusting an incremental path measurement unit in an actuation device of a pressure-closed clutch as well as an actuation device
    Patent number: 7350634
    Abstract: Actuation devices are disclosed for a pressure-closed clutch where the position of an actuation member is acquired by an incremental sensor. In an embodiment of the actuation device, the signal of the incremental sensor is acquired in case of a sudden change in the power consumption of an actuator and is used as a new reference signal. In another embodiment, the actuation member, while the spindle is rotating, is moved by a recovery spring during the closing of the clutch against a stop and the signal of the incremental sensor upon the attainment of said stop is used as a reference signal.
