Abstract
A shifting arrangement of an automatic transmision of a motor vehicle has a selector lever which can be pivoted in two shifting paths. In the first shifting path of the selector lever, various operating positions and automatically shifting gears of the transmission may be selected via a transmitting device. The selector lever can be changed over into a second shifting path in which, by a one-time pivoting of the selector lever from a center position, an upshifting or return shifting may take place by one gear respectively. A locking device interacts with the transmitting device so that the transmitting device, from which the selector lever is separated in the second shifting path, is held in its intended position.
Claims11
A shifting arrangement for an automatic transmission of a motor vehicle which is influenced by an electronic control unit, comprising:
- a selector lever pivotable in a first shifting path to select several operating positions and automatically shifting transmission gears, movable via a transverse path into a second shifting path parallel with respect to the first shifting path, a pivoting of the selector lever in a first direction from a neutral center position in the second shifting path causing an upshifting by one gear and a pivoting in a second direction from the neutral center position causing a downshifting by one gear;
- a transmitting device coupled to the selector lever in the first shifting path to transmit movements of the selector lever to shift the operating positions and automatically shift gears, said transmitting device including a driving dog that interacts with the selector lever;
- a shaft extending transversely with respect to a longitudinal direction of the motor vehicle, said selector lever and said driving dog being rotatably disposed on said shaft;
- a locking device that interacts with the transmitting device to lock the transmitting device when the selector lever is in the second shifting path.
