Gearbox actuation system and method for adjusting a gearbox actuation system
View Patent ↗A method for the adjustment of a gearbox actuation system of an automated gearbox of a vehicle. The gearbox includes a shift finger; a plurality of gearshift rails, each rail in the plurality of gearshift rails in a respective position; a neutral gap with a first portion formed by respective jaws for said each rail and with a second portion formed separate from the respective jaws and open to the first portion; and, a gearshift motor. The method includes the step of performing at least one reference travel with a gear in the automated gearbox engaged.
1. A method for the adjustment of a gearbox actuation system of an automated gearbox of a vehicle, wherein the gearbox includes a shift finger; a plurality of gearshift rails, each rail in the plurality of gearshift rails in a respective position; a neutral gap with a first portion formed by respective jaws for said each rail and with a second portion formed separate from the respective jaws and open to the first portion; and, a gearshift motor, comprising the step of performing at least one reference travel with a gear in the automated gearbox engaged.
2. The method according to claim 1 , wherein the gearbox actuation system includes a plurality of gearshift forks and wherein the gearbox actuation system is so made that a reference point is started in the neutral gap without the particular gearshift forks and gearshift rails being moved at the same time.
3. The method according to claim 1 , wherein the gearbox actuation system includes a plurality of gearshift jaws and wherein the gearshift rails form a gap with their particular gearshift jaws in which gap the shift finger is moved to start reference points.
4. The method according to claim 1 , wherein the shift finger is moved laterally in the direction of the neutral gap and, at the same time, reference points are started periodically upward and downward.
5. The method according claim 1 , wherein the neutral gap includes a width and wherein a direction of selection is adjusted when the shift finger is moved over the entire neutral gap width.
6. The method according to claim 1 , wherein an adjustment in a gearshift direction is performed parallel to the gearshift rails by means of the second portion of the neutral gap.
7. The method according to claim 1 , wherein the gearbox actuation system includes a starting position for the shift finger and wherein the shift finger is again moved back into the starting position prior to the reference travel after referencing.
8. The method according to claim 1 , wherein said at least one reference travel is performed regularly or irregularly to start reference points.
