Damping device for a selector shaft and gearshift tower having the damping device
View Patent ↗A damping device for a selector shaft, having a damper weight with a damper unit, and having a guide device. The guide device guides the damper weight in a circumferential direction about the pivoting axis of the selector shaft. The damper weight is guided in the circumferential direction so that it is damped by the damper unit. The guide device also guides and/or holds the damper weight rigidly and/or without damping in the radial direction with respect to the pivoting axis. The damper unit is arranged off-center, asymmetrically and/or eccentrically with respect to the pivoting axis, and/or the damper weight and the damper unit form a damping absorber device arranged outside the force transmission path for the shifting and/or selection movement of the selector shaft.
1. A damping device for a selector shaft, comprising:
a damper weight; a damper unit; and a guide device,
wherein the guide device is arranged to guide the damper weight in a circumferential direction about a pivoting axis of the selector shaft, wherein the damper weight is guided in the circumferential direction so as to be damped by the damper unit,
wherein the guide device is also arranged to hold the damper weight without damping in a radial direction with respect to the pivoting axis,
wherein one of:
the damper unit is arranged one of off-center, asymmetrically and eccentrically with respect to the pivoting axis, and
the damper weight and the damper unit form a damping absorber device arranged outside of a force transmission path of a shifting movement or a selection movement of the selector shaft.
2. The damping device according to claim 1 , and further comprising a damper arm, wherein the damper weight is arranged on the damper arm with the damper unit connected between the damper weight and the damper arm.
3. The damping device according to claim 2 , wherein the damper arm is coupled to the selector shaft so that the damper arm is fixed with respect to rotation relative to the selector shaft.
4. The damping device according to claim 2 , and further comprising a guide arm, wherein the damper weight is coupled to the guide arm without damping or rigidly.
5. The damping device according to claim 4 , wherein the guide arm is mounted so as to be freely rotatable on the selector shaft.
6. The damping device according to claim 4 , wherein the guide arm and the damper weight are each a one piece cast component.
7. The damping device according to claim 4 , wherein at least one of the damper arm and the guide arm a sheet metal structure.
8. The damping device according to claim 2 , wherein the guide device comprises a coupling section that has an interface for initiating the shifting and selection movements.
9. The damping device according to claim 8 , wherein the coupling section is arranged on the damper arm.
10. The damping device according to claim 1 , wherein the damper unit has a hollow cylindrical shape.
11. The damping device according to claim 1 , wherein the damper weight has a barbell shape or a barbell handle.
12. The damping device according to claim 11 , wherein the damper arm has a hollow cylinder section that engages around the damper weight and the damper unit.
13. A gearshift tower, comprising:
a selector shaft for transmitting shifting movements or selection movements, the selector shaft being at least one of pivotal and displaceable; and
a damping device for damping of oscillations or vibrations of the selector shaft during the shifting movements or the selection movements, the damping device including a damper weight; a damper unit; and a guide device, wherein the guide device is arranged to guide the damper weight in a circumferential direction about a pivoting axis of the selector shaft, wherein the damper weight is guided in the circumferential direction so as to be damped by the damper unit, wherein the guide device is also arranged to hold the damper weight without damping in a radial direction with respect to the pivoting axis, wherein one of:
the damper unit is arranged one of off-center, asymmetrically and eccentrically with respect to the pivoting axis, and
the damper weight and the damper unit form a damping absorber device arranged outside of a force transmission path of a shifting movement or a selection movement of the selector shaft, and
the damping device further comprising a damper arm, wherein the damper weight is arranged on the damper arm with the damper unit connected between the damper weight and the damper arm, and a guide arm, wherein the damper weight is coupled to the guide arm with without damping or rigidly.
14. The gearshift tower according to claim 13 , wherein the selector shaft has a a mechanical interface for receiving the guide arm in a freely rotatable fashion.
15. The gearshift tower according to claim 14 , wherein the selector shaft has a positively locking section for connecting the damper arm in a non-pivoting fashion.
16. The gearshift tower according to claim 13 , wherein the selector shaft has a positively locking section for connecting the damper arm in a non-pivoting fashion.
