Automobile gearbox comprises primary shaft and two secondary shafts and two synchronizers with dogging sleeves connected to translate together

摘要

The gearbox comprises a primary shaft, a first secondary shaft (4) on which a first pinion (6) idles, and a first synchronizer (20) which synchronizes the rotational speed of the first pinion with the first secondary shaft rotational sped. This first synchronizer comprises a first ring dogging sleeve (22). The gearbox comprises a second secondary shaft (8), a second synchronizer (40) synchronizing the rotational speed of the first pinion with the rotational speed of the second secondary shaft. The second synchronizer comprises a second ring dogging sleeve (42) connected to translate with the first ring dogging sleeve.
