A transmission system for either a manual shift transmission, an automatic transmission or an automated transmission in which the electrical connections and the pneumatic connections including any ventilation port, for the internal components of the transmission are combined with one another so as to exit the transmission housing via a single unified connection formed in the housing wall of the transmission.

Transmission system

A shifting device () for a transmission with a selection actuator and a shifting actuator, which a shifting shaft () comprising shifting forks () or selector forks, which engage in sliding collars for engaging the gears in which the shifting motion can be carried out by way of an axial motion of the shifting shaft (), while the selection motion is kinematically disengaged from the shifting motion and the shifting shaft () does not rotate during the selection motion.

Shifting device for a transmission

An electromagnetic actuator and a method for controlling the actuator comprising at least one armature () and two coils (). The voltage gradient at the two coils () is measured during a sudden increase in voltage. From this measured data, a subtractor () computes a third voltage gradient () from which a logic unit () determines the position of the armature () without the use of an additional sensor.

Position recognition in an electromagnetic actuator without sensors

An electromechanically activated motor vehicle transmission () such as an automated manual transmission () or a transfer case (). This transmission includes at least a transmission housing (), an electromagnetic selecting or shifting device () and an electric motor () by which the selecting or shifting device () can be actuated. In the inventive motor vehicle transmission (), the electric motor () of the selecting or shifting mechanism () arranged within the transmission housing () and the motor housing () of the electric motor () is designed so that it corresponds to a portion of the transmission housing ().

Vehicle gearbox with an integrated electric motor

A device and a method for determining the position of a gear shift elementin a claw clutch operated automated gear box of a vehicle. The gear shift elementhas gear teeth that correspond to at least two gear wheelswhich have a different axial extension on both sides of a groove. The position of the gear shift elementcan be determined by way of the method according to the invention.
