SCHALTGESTAENGE MIT EIN MANUELL SCHALTBARES GETRIEBE

摘要

A manually-actuated six speed transmission (10) for use in an automotive vehicle wherein a vehicle operator actuates said transmission through a shift lever (82) actuating a primary shift rail (81) in the transmission housing (11), the transmission including an input shaft (12), an output shaft (13) axially aligned with the input shaft, a countershaft (15) having a gear cluster (17) thereon, the input shaft terminating in an input gear (14) which also acts as a fourth gear for direct drive, a plurality of gears (18, 19, 20, 21, 22, 23, 24) on the countershaft providing first through sixth gears and reverse, and a plurality of synchronizers (36, 38, 41, 42) on either the output shaft (13) or the countershaft (15) for actuating said gears. The synchronizers include a 1-2 synchronizer (36), a 3-4 synchronizer (38) and a reverse synchronizer (42) encompassing the output shaft (13), and a 5-6 synchronizer (41) encompassing the countershaft (15). An auxiliary shift rail (98) is provided in the housing positioned generally between the output shaft (13) and countershaft (15) for the 5-6 shift fork (69) and the reverse shift fork (77) without the complicated linkages previously found in five and six speed transmissions.
