摘要： A transmission includes a plurality of pneumatic actuators for gear shifting, wherein the pneumatic actuators are arranged to discharge compressed air via a common ventilation system including at least one ventilation opening arranged in a housing arrangement of the transmission. A method for controlling ventilation of the transmission includes determining that a predetermined flushing condition is fulfilled and, in response thereto, initiating a flushing action in which at least two of the pneumatic actuators are controlled to discharge compressed air simultaneously or substantially simultaneously to the common ventilation system so as to force air through the at least one ventilation opening.

摘要： An automated manual transmission, comprising:
a transmission control unit,
a shift rod movable between a predetermined first position in which it engages a first gear combination of the transmission, a predetermined second position in which it engages a second gear combination of the transmission, and a predetermined neutral position in which it does not engage any gear,
an actuator for moving the shift rod between the first position, the second position and the neutral position by applying a fluid pressure acting on the shift rod in response to signals from the transmission control unit,
mechanical engagement means for maintaining the first and second positions of the shift rod without applying any fluid pressure by means of the actuator,
wherein the transmission is adapted to maintain the neutral position of the shift rod solely by applying fluid pressure acting on the shift rod.-

摘要： An interlocking device for a transmission is provided, where the transmission includes a pivotable first shift fork for selectively engaging a first gear and a slidable second shift fork for selectively engaging a second gear. The interlocking device includes a pivot arm pivotable between a first position and a second position, and having a first end and a second end. The first end includes a first interacting portion that interacts with a first locking member of the first shift fork. The second end includes a second interacting portion that interacts with a second locking member of the second shift fork. In the first position, pivoting movement of the first shift fork is prevented and relative sliding movement of the second shift fork is allowed, and in the second position, relative pivoting movement of the first shift fork is allowed and relative sliding movement of the second shift fork may be prevented.

摘要： A transmission assembly for a powertrain of a vehicle, includes,
a control device and a transmission housing for housing a transmission, the control device mountable to the transmission housing and including a transmission mounting surface adapted to face the transmission housing,
the transmission housing including a control device mounting surface adapted to face the control device,
one of the transmission mounting surface and the control device mounting surface including a groove including at least a first and a second step deeper than the first step, and
the other of the transmission mounting surface and the control device mounting surface including an outwardly extending guiding member configured to be received in the groove, configured so that the outwardly extending guiding member can slide in the first step until it reaches the second step, whereafter the transmission mounting surface can be moved towards the control device mounting surface or vice versa.-
