Multi-speed transaxle

Claim 2

In a transmission having a housing for containing gears and a pair of axially aligned shafts carrying the gears, the housing having side walls and a connecting wall, the shafts having facing ends separated from each other, the improvement of a supporting member carried by a side wall of the housing a distance from the end walls of the housing, said supporting member supporting one of the shafts of said aligned shafts at a location spaced from the end of said shaft, the end of said shaft supported by the supporting member protruding from said supporting member, a gear having a centrally disposed hole carried on the end of one of the shafts of said aligned shafts, said gear being non rotatably carried by the other shaft of said aligned shafts, the said protruding end of the shaft supported by the supporting member extending into the centrally disposed hole of said gear, the arrangement providing for the bearing support of said non-supported shaft by said supporting member through dependence on the supported shaft while permitting the shafts to rotate independently of each other.

Claim 3

The structure of claim 1 characterized by a separate bearing interposed between said gear and the end of the other shaft not supported by said supporting member.

Claim 4

In a transmission having a housing for containing gears and first and second axially aligned shafts carrying the gears, the housing having side walls and a connecting wall, the shafts having facing ends separated from each other for permitting rotation of the shafts independently of each other, the improvement of a supporting member carried by a side wall of the housing a distance from the end walls of the housing, said supporting member supporting the first shaft a spaced distance from the end of said first shaft, the end of said first shaft protruding from said supporting member toward the second shaft, a gear non-rotatably carried on the end of the second shaft for rotation therewith, said gear having a central hole therein accommodating in the hole the protruding end of the first shaft, said gear rotatably journaled on the end of the first shaft for rotation therearound and providing for the bearing support of the end of the second shaft by the supporting member through the first shaft while permitting the shafts to rotate independently of each other.

Claim 5

In a transmission having a housing for containing gears and first and second axially aligned shafts carrying the gears, the housing having side walls and a connecting wall, the shafts having facing ends separated from each other for permitting rotation of the shafts independently of each other, the improvement of a supporting member carried by a side wall of the housing a distance from the end walls of the housing, said supporting member supporting the first shaft a spaced distance from the end of said first shaft, the end of said first shaft protruding from said supporting member toward the second shaft, a gear non-rotatably carried on the end of the second shaft for rotation therewith, said gear having a central hole therein accommodating in the hole the protruding end of the first shaft, said gear rotatably journaled on the end of the first shaft for rotation therearound and providing for the bearing support of the end of the second shaft by the supporting member through the first shaft while permitting the shafts to rotate independently of each other.

Claim 6

The structure of claim 3 characterized by a separate bearing within said central hole interposed between said gear and the end of the protruding end of the first shaft.

Claim 7

The structure of claim 4 wherein said gear has a recess in the fact thereof, the recess being in axial alignment with said shafts and having an inner wall, and wherein the protruding end portion of the first shaft and the bearing about said protruding end protrude into said recess with the bearing member in engagement with the inner wall of the recess.

Claim 8

In a transmission having a housing for containing gears and first and second axially aligned shafts carrying the gears, the housing having end walls and side walls, the shafts having facing ends separated from each other for permitting rotation of the shafts independently of each other, the improvement of a supporting member carried by a side wall of the housing a distance from the end walls of the housing, said supporting member supporting the first shaft a spaced distance from the end of said first shaft, the end of said first shaft protruding from said supporting member toward the end of the second shaft, a gear, said gear having two portions, said two portions of said gear having differing diameters, said gear being non-rotatably connected to the end of the second shaft for rotation therewith by one portion of said gear, the other portion of said gear extending beyond the end of the second shaft, said other portion of said gear having a central recess in the face thereof, said recess being in axial alignment with said shafts and having an inner wall and the end portion of the first shaft protruding into said recess in rotational operative inter-engagement with the inner wall of the recess, the arrangement providing for the bearing support of the end of the second shaft by the supporting member by dependence on the first shaft while permitting the shafts to rotate independently of each other.

Claim 9

In a transmission having a housing for containing gears and first and second axially aligned shafts carrying the gears, the housing having end walls and side walls, the shafts having facing ends separated from each other for permitting rotation of the shafts independently of each other, the improvement of a supporting member carried by a side wall of the housing a distance from the end walls of the housing, said supporting member supporting the first shaft a spaced distance from the end of said first shaft, the end of said first shaft protruding from said supporting member toward the end of the second shaft, a gear, said gear having two portions, said two portions of said gear having differing diameters, said gear being non-rotatably connected to the end of the second shaft for rotation therewith by one portion of said gear, the other portion of said gear extending beyond the end of the second shaft, said other portion of said gear having a central recess in the face thereof, said recess being in axial alignment with said shafts and having an inner wall and the end portion of the first shaft protruding into said recess in rotational operative inter-engagement with the inner wall of the recess, the arrangement providing for the bearing support of the end of the second shaft by the supporting member by dependence on the first shaft while permitting the shafts to rotate independently of each other.

Claim 10

The structure of claim 6 characterized by the addition of another gear, a third shaft and a differential, said other gear having a diameter different from said two portions of said gear, said other gear being non-rotatably connected to the second shaft next to said one portion of said gear, said one portion of said gear drivingly connected to the differential and means to selectively drivingly connect the other portion of said gear or said other gear to the third shaft, said arrangement providing for a two speed balanced connection between the third shaft and the differential.

Claim 11

The structure of claim 6 characterized by the addition of a bearing and said bearing being in said recess between said inner wall of said recess and the end portion of the first shaft.
