Abstract
A shifting device with a gearshift lever for an automatic transmission of a motor vehicle is provided with an unlocking mechanism for unlocking the gearshift lever with a manual actuating element. The gearshift lever can be moved, in at least one shift gate, between two different shift positions and can be locked at least partially in these shift positions as a function of different vehicle configurations. A spring-tensioned force transmission element is provided in the unlocking mechanism.
Claims16
A shifting device, comprising:
- a gearshift lever for an automatic transmission of a motor vehicle, said gear shift lever having a shift knob;
- a manual actuating element mounted movably to said shift knob, said gearshift lever being moved in at least one shift gate between two different shift positions and being locked at least partially in one of said shift positions as a function of different vehicle configurations;
- an unlocking mechanism for unlocking said gearshift lever with a locking bar and a spring-tensioned force transmission element including a spring support with a pushing and pivoting connection with said actuating element and mounted pivotably about a pivot axis in said shift knob, and a spring braced on said spring support with a first spring arm clamped at two first spring arm sides to said spring support and a second spring arm limited on one side by a spring stop of said spring support and operatively connected to said locking bar for moving said locking bar upon a movement of said manual actuating element when said locking bar is unblocked and such that the manual actuating element can be moved without moving said locking bar when said locking bar is blocked.
A shifting device, comprising:
- a gearshift lever for an automatic transmission of a motor vehicle said gear shift lever having a shift knob;
- a manual actuating element connected to said gear shift lever, said gearshift lever being moved in at least one shift gate between two different shift positions and being at least partially lockable in one of said shift positions;
- an locking bar connect to said gearshift lever and movable generally in an up and down direction;
- and
- a transmission element connecting said manual actuating element to said unlocking mechanism, said transmission element including spring support with a pushing and pivoting connection with said actuating element and mounted pivotably about a pivot axis in said shift knob and a tensioned resilient means with a first spring arm fixed relative to said spring support and a second spring arm limited on one side by a spring stop of said spring support and operatively connected to said locking bar for moving said locking bar upwardly, upon pushing on said manual actuating element when said locking bar is unblocked and for deforming resiliently relative to said locking bar and not moving said locking bar upwardly, upon pushing on said manual actuating element when said locking bar is blocked.
