Gearbox for car involves disengaging coupling of gear co-axial with output shaft done by another gear engaged with both gear and output shaft

摘要

Gearbox has input shaft (2) with gear (8), countershaft (3) with three gears (9,10,11) and coupled to input shaft by gear (12), and output shaft (1), parallel to other shafts and with four gears (4, 5, 6, 7) gearing with gears (8, 9, 10, 11). Disengaging coupling of gear (4) with output shaft is done by gear (5), co-axial with gear (4) and that is geared into gear (4) and output shaft.
