Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
110 words
In a transmission, a housing, input and output shafts rotatably supported by said housing, a plurality of ratio output gears rotatably supported by said output shaft, a countershaft rotatably supported by said housing and engaged with said input shaft for rotation thereby, and an extension supported by said countershaft and said housing for rotation with said countershaft, said extension being movable transverse to the axis of rotation of said countershaft, said countershaft and extension each defining at least one ratio input gear, said ratio input gears respectively engaged with said ratio output gears, said ratio output gears selectively engageable with said output shaft for establishing a plurality of drive ratios.
Claim 2
Dependent Claim
110 words
In a transmission, a housing, input and output shafts rotatably supported by said housing, a plurality of ratio output gears rotatably supported by said output shaft, a countershaft rotatably supported by said housing and engaged with said input shaft for rotation thereby, and an extension supported by said countershaft and said housing for rotation with said countershaft, said extension being movable transverse to the axis of rotation of said countershaft, said countershaft and extension each defining at least one ratio input gear, said ratio input gears respectively engaged with said ratio output gears, said ratio output gears selectively engageable with said output shaft for establishing a plurality of drive ratios.
Claim 3
Dependent Claim
35 words
The invention according to claim 1, said countershaft journalled in first and second bearings in said housing, said extension journalled in a third bearing in said housing and splined to said countershaft for rotation therewith.
Claim 4
Dependent Claim
82 words
The invention according to claim 2, said countershaft extending through said second bearing and defining a limit stop and an end poRtion having a boss thereon, said extension including means defining a limit stop secured to and axially spaced from said end portion and further including a sleeve splined to said end portion and overlying said boss, said sleeve being movable axially along said boss between said limit stops and pivotally about said boss, said sleeve defining said extension ratio input gear.
Claim 5
Dependent Claim
117 words
In combination, a housing, a shaft having a main portion of relatively large diameter journalled in first and second bearings in said housing, said shaft extending through said second bearing and having an end portion of relatively small diameter defining an upstanding boss thereon, said portions defining a limit stop therebetween, a shaft extension journalled in a third bearing in said housing, said extension including a spacer secured to said end portion and extending axially therefrom, a limit stop secured to said spacer, and a sleeve splined to said end portion and axially movable between said limit stops guided by said boss, said sleeve being pivotal transversely about said boss to compensate for misalignment of said bearings.
Claim 6
Dependent Claim
117 words
In combination, a housing, a shaft having a main portion of relatively large diameter journalled in first and second bearings in said housing, said shaft extending through said second bearing and having an end portion of relatively small diameter defining an upstanding boss thereon, said portions defining a limit stop therebetween, a shaft extension journalled in a third bearing in said housing, said extension including a spacer secured to said end portion and extending axially therefrom, a limit stop secured to said spacer, and a sleeve splined to said end portion and axially movable between said limit stops guided by said boss, said sleeve being pivotal transversely about said boss to compensate for misalignment of said bearings.
