Abstract
Abstract A transfer mechanism for use in a motor vehicle assembly having a source of power and a pair of first and second aligned axles, the transfer mechanism including a planetary spur gear train formed of three elements, i.e., a sun gear, a set of planetary pinions and an internal ring gear in mesh with the planetary pinions. A stationary member supports the three elements and a control system is provided for changing the meshing relation between the elements.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
180 words
In a transfer mechanism for use in a motor vehicle assembly having a source of power and a pair of first and second driven axles aligned with each other, said transfer mechanism including: a three-element planetary gear train consisting of a sun gear, a carrier with at least one pinion gear thereon in mesh with said sun gear and an internal ring gear in mesh with said pinion gear; means connecting one of said three elements in driving relation with said source of power; a second of said three elements being integrally connected with said first driven axle for rotation therewith; a stationary member mounted on a stationary portion of the vehicle and control means for selectively engaging the remaining one of said three elements with said stationary member, said second driven axle, or both said second driven axle and said first one of said three elements, such that said three element planetary gear can be actuated as a differential gear as well as a speed change gear with one of said driven axles isolated frOm said source of power.
Claim 2
Dependent Claim
180 words
In a transfer mechanism for use in a motor vehicle assembly having a source of power and a pair of first and second driven axles aligned with each other, said transfer mechanism including: a three-element planetary gear train consisting of a sun gear, a carrier with at least one pinion gear thereon in mesh with said sun gear and an internal ring gear in mesh with said pinion gear; means connecting one of said three elements in driving relation with said source of power; a second of said three elements being integrally connected with said first driven axle for rotation therewith; a stationary member mounted on a stationary portion of the vehicle and control means for selectively engaging the remaining one of said three elements with said stationary member, said second driven axle, or both said second driven axle and said first one of said three elements, such that said three element planetary gear can be actuated as a differential gear as well as a speed change gear with one of said driven axles isolated frOm said source of power.
Claim 3
Dependent Claim
64 words
The transfer mechanism of claim 1 wherein, said control means includes a single manually operable member and an axially slidable first sleeve member drivenly connected to said manually operable member and always connected to said sun gear in aligned relation, said first sleeve member being operatively and selectively connected in meshed relation with said stationary member, said source of power or said second axle.
Claim 4
Dependent Claim
30 words
The transfer mechanism of claim 2 further comprising a second sleeve member in aligned relation with said first sleeve member and normally spring biased to abut said first sleeve member.
Claim 5
Dependent Claim
30 words
The transfer mechanism of claim 1 wherein said planetary arm is drivenly connected with said source of power and said ring gear is drivingly connected to said first driven axle.
Claim 6
Dependent Claim
30 words
The transfer mechanism of claim 1 wherein said planetary arm is drivingly connected to said first driven axle and said ring gear is drivenly connected to said source of power.
