Abstract
A compound transmission shift mechanism is disclosed. The shift mechanism includes a plurality of gears configured on at least one transmission shaft with at least one synchronizer configured to engage at least two of the plurality of gears. The shift mechanism includes a control system configured to engage and position the synchronizer into alignment with the at least two of the plurality of gears. Additionally, the shift mechanism includes at least one damping assembly configured on the control system and operatively connected to the synchronizer.
Claims20
A rail selector for use with a compound transmission shift mechanism, comprising:
- a plurality of gears configured on at least one transmission shaft;
- a synchronizer configured on at least two of the plurality of gears;
- a control system configured to engage and position the synchronizer into alignment with at least two gears on the transmission shaft;
- a damping assembly on the control system and operatively connected to the synchronizer, and configured to translate movement of a shift lever through a shift rail and through shift forks that are configured to engage the synchronizer;
- wherein the damping assembly includes a rail selector having wings, operatively connected to the shift forks that extend in a lateral direction from a shaft passing axially through a center of the damping assembly.
A transmission shift mechanism, comprising:
- two or more gears configured on a transmission shaft;
- a synchronizer configured to engage two of the two or more gears;
- and
- a control system including shift forks and a main shift rail damping assembly operatively connected to engage and position the synchronizer into alignment with the two gears, wherein the damping assembly includes a rail selector having laterally extending wings operatively connected to the shift forks;
- wherein the synchronizer includes a pre-energizer configured with at least one of a roller, a plunger and a spring;
- and
- wherein the synchronizer includes at least one fixed synchronization hub configured between at least two synchronizing rings, which are positioned between two gear flanges.
