Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
194 words
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.
Claim 2
Dependent Claim
194 words
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.
Claim 3
Dependent Claim
68 words
The shifting arrangement according to claim 1, further comprising a spring and wherein the locking device includes a locking element and a pin, said locking element being rotatably arranged via said pin at said driving dog, said locking element being pivotable from an unlocked position into a locked position under the effect of said spring and as a function of the shifting path position of the selector lever.
Claim 4
Dependent Claim
34 words
The shifting arrangement according to claim 2, further comprising a stationary component having a plate with an opening, said locking element engaging in said opening when said locking element is in the locked position.
Claim 5
Dependent Claim
25 words
The shifting arrangement according to claim 3, wherein the plate extends perpendicularly with respect to the shaft and includes a bore that surrounds said shaft.
Claim 6
Dependent Claim
26 words
The shifting arrangement according to claim 4, wherein the shifting arrangement includes a housing with an upright wall, the plate extending adjacent to said upright wall.
Claim 7
Dependent Claim
36 words
The shifting arrangement according to claim 2, wherein the locking member, on both sides of a transverse center plane intersecting the pin, has latches extending away from a thickening which are arranged in a mirror-inverted manner.
Claim 8
Dependent Claim
31 words
The shifting arrangement according to claim 6, wherein the shifting arrangement includes an opening and the upper latch interacts with said opening and the lower latch interacts with the selector lever.
Claim 9
Dependent Claim
39 words
The shifting arrangement according to claim 6, wherein the driving dog has supporting ramps and the spring is a leaf spring which, penetrating the thickening, extends in a longitudinal direction of the latches and interacts with the supporting ramps.
Claim 10
Dependent Claim
15 words
The shifting arrangement according to claim 8, wherein the leaf spring extends around the pin.
Claim 11
Dependent Claim
20 words
The shifting arrangement according to claim 1, wherein the driving dog includes a fork-type section that surrounds the selector lever.
Claim 12
Dependent Claim
44 words
The shifting arrangement according to claim 1, further comprising at an end opposite a free side grip of the selector lever, a spring detent arrangement that fixes the position of the selector lever in the first shifting path and in the second shifting path.
