Abstract
A manual transmission (11) is provided of the type including an input shaft (15) including an input gear (19), an output shaft (23), and a countershaft including a head gear (44). The counter shaft includes drive gears (41, 42, and (43) while the output shaft has rotatably mounted thereon a plurality of driven gears (31, 32, and 33) in toothed engagement with the drive gears. The head gear defines a set of internal splines (55), and the countershaft defines a set of external splines (57) which are in loose, splined engagement to define a lost motion connection. The head gear defines a pair of cam surfaces (59), and the countershaft includes a pair of cam members (61) and a compression spring (63), operable to bias the cam members against the cam surfaces, and bias the countershaft toward a centered position, relative to the head gear. The head gear and countershaft define a viscous damper portion (65) disposed separately from the lost motion means, including a viscous shear space ( 69), which is operable when filled with viscous fluid to dampen relative rotation between the countershaft and the head gear.
