Abstract

Abstract A driving gear system, suitable for use in connection with a vehicle having a three speed transmission, and for use in connection with a high-power vehicle having an adjustable track width, the vehicle including a differential gear system having first bearing means, features a bridge housing mounted on said vehicle, a first planetary gear system disposed in the bridge housing and including a first sun wheel, a plurality of first planet wheels, each having a first radius, and first supporting means operable for supporting the first planet wheels, a second planetary gear system disposed in the bridge housing and including a second sun wheel, a plurality of second planet wheels, each having a second radius, and second supporting means operable for supporting the second planet wheels and mounted for coaxial rotation with respect to the second sun wheel, the second radii being smaller than the first radii, the first bearing means being disposed in the first supporting means, housing shells connected to the bridge housing, connecting means operable for connecting the housing shells to a central portion of the bridge housing and for connecting the first supporting means to the bridge housing, the first sun wheel being mounted on a portion of the second supporting means for rotation therewith, and a second bearing means disposed between the first and second supporting means and operable to allow the rotation of the second supporting means relative to the first supporting means.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 244 words
A driving gear system, suitable for use in connection with a vehicle having a three speed transmission and for use in connection with a high-power vehicle having an adjustable track width; said vehicle including a differential gear system having first bearing means; said driving gear system comprising, in combination: a bridge housing mounted on said vehicle; a first planetary gear system disposed in said bridge housing and including: a first sun wheel; a plurality of first planet wheels, each having a first radius; and first supporting means operable for supporting said first planet wheels; a second planetary gear system disposed in said bridge housing and including: a second sun wheel; a plurality of second planet wheels, each having a second radius; and second supporting means operable for supporting said second planet wheels and mounted for coaxial rotation with respect to said second sun wheel; said second radii being smaller than said first radii; said first bearing means being disposed in said first supporting means; housing shells connected to said bridge housing; connecting means operable for connecting said housing shells to a central portion of said bridge housing and for connecting said first supporting means to said bridge housing; said first sun wheel being mounted on a portion of said second supporting means for rotation therewith; and second bearing means disposed between said first and second supporting means and operable to allow the rotation of said second supporting means relative to said first supporting means.
Claim 2
Dependent Claim 244 words
A driving gear system, suitable for use in connection with a vehicle having a three speed transmission and for use in connection with a high-power vehicle having an adjustable track width; said vehicle including a differential gear system having first bearing means; said driving gear system comprising, in combination: a bridge housing mounted on said vehicle; a first planetary gear system disposed in said bridge housing and including: a first sun wheel; a plurality of first planet wheels, each having a first radius; and first supporting means operable for supporting said first planet wheels; a second planetary gear system disposed in said bridge housing and including: a second sun wheel; a plurality of second planet wheels, each having a second radius; and second supporting means operable for supporting said second planet wheels and mounted for coaxial rotation with respect to said second sun wheel; said second radii being smaller than said first radii; said first bearing means being disposed in said first supporting means; housing shells connected to said bridge housing; connecting means operable for connecting said housing shells to a central portion of said bridge housing and for connecting said first supporting means to said bridge housing; said first sun wheel being mounted on a portion of said second supporting means for rotation therewith; and second bearing means disposed between said first and second supporting means and operable to allow the rotation of said second supporting means relative to said first supporting means.
Claim 3
Dependent Claim 23 words
The driving gear system as claimed in claim 1, further comprising a first toothed rim in driving engagement with said first planet wheels.
Claim 4
Dependent Claim 50 words
The driving gear system as claimed in claim 2, further comprising a second toothed rim in driving engagement with said second planet wheels and said first rim, whereby power transmitted by said differential gear system can be transmitted to said first rim by said first and second planetary gear systems.
Claim 5
Dependent Claim 32 words
The driving gear system as claimed in claim 3, wherein said first and second rims include teeth which loosely engage each other, whereby the engagement is to a limited extent substantially self-adjustable.
