Abstract
Abstract A power takeoff alternator assembly is provided for use as a main source of continuous electrical energy for battery charging and other electrical equipment requirements during the normal operation of trucks, buses, tractors and other commercial vehicles. The assembly comprises a housing in which a power takeoff unit and an alternator are rigidly mounted in axial alignment and mechanically coupled by means of a keyed flexible dynamic coupling. The housing is specially adapted for mounting the assembly as a unitary package to any standard transmission designed to receive a conventional power takeoff unit.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
193 words
An assembly for producing electrical energy in an automotive vehicle having a transmission comprising: a source of electrical energy having an armature shaft; a gear assembly having an input shaft and an output shaft; a means for frictionally coupling said armature shaft of said energy source and said output shaft of said gear assembly, said coupling means having a first means coupled to said armature shaft and a second means coupled to said output shaft, said first and said second means having facing surfaces which slip relative to each other for permitting relative rotation betwen said armature shaft and said output shaft in response to a predetermined force; and a relatively rigid housing having a base portion with a substantially vertical flange portion attached thereto, said source mounted on said flange portion and said gear assembly mounted on said base portion, for receiving said source and said gear assembly, said housing including means for maintaining said armature shaft in substantial coaxial alignment with said output shaft, a means for mounting said housing to a transmission in a vehicle, and a means for coupling said input shaft of said gear assembly to said transmission.
Claim 2
Dependent Claim
193 words
An assembly for producing electrical energy in an automotive vehicle having a transmission comprising: a source of electrical energy having an armature shaft; a gear assembly having an input shaft and an output shaft; a means for frictionally coupling said armature shaft of said energy source and said output shaft of said gear assembly, said coupling means having a first means coupled to said armature shaft and a second means coupled to said output shaft, said first and said second means having facing surfaces which slip relative to each other for permitting relative rotation betwen said armature shaft and said output shaft in response to a predetermined force; and a relatively rigid housing having a base portion with a substantially vertical flange portion attached thereto, said source mounted on said flange portion and said gear assembly mounted on said base portion, for receiving said source and said gear assembly, said housing including means for maintaining said armature shaft in substantial coaxial alignment with said output shaft, a means for mounting said housing to a transmission in a vehicle, and a means for coupling said input shaft of said gear assembly to said transmission.
Claim 3
Dependent Claim
49 words
An assembly according to claim 1 wherein one of said first and said second means in said coupling means includes a resilient member which cooperates with said means for maintaining said armature shaft in substantial coaxial alignment with said output shaft for preventing destructive sideloading of said armature shaft.
Claim 4
Dependent Claim
20 words
An assembly according to claim 2 wherein said source is an alternator and said gear assembly is a power-take-off unit.
Claim 5
Dependent Claim
35 words
An assembly according to claim 3 wherein said means for coupling said input shaft of said gear assembly to said transmission comprises an access hole in said housing for providing access to said input shaft.
