Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
225 words
A vehicle powerplant comprising first thermal drive means and second electrical drive means; said first and second means being activated for transmitting motion to the drive wheels of the vehicle via a transmission (2); said first drive means comprising a combustion engine (1) connected mechanically to said wheels by a drive line (3) fitted with said transmission (2) and with a clutch (4) located between said engine (1) and said transmission (2) and which may be set to a first and second position wherein said combustion engine (1) is respectively connected to and disconnected from said transmission (2); characterized by the fact that it comprises: a current generator (7) for supplying electric current to a storage battery (8), and the rotor element of which is connected to said drive line (3) upstream from said clutch (4); an electric motor (10), the rotor element of which is connected by a first drive (11) to said drive line (3) downstream from said clutch (4), said electric motor (10) being driven by the current supplied by said battery (8); a second clutch (12) located between the rotor element of said electric motor (10) and said drive line (3), and which may be set to a first and second position wherein said rotor element of said motor (10) is respectively connected to and disconnected from said drive line (3).
Claim 2
Dependent Claim
64 words
A powerplant as claimed in Claim 1, characterized by the fact that it also comprises a shaft (5) connected by a second drive (6) to said drive line (3) upstream from said clutch (4), and which provides for a power takeoff (9) for operating the accessory devices of said vehicle; the rotor element of said current generator (7) being connected to said shaft (5).
Claim 3
Dependent Claim
80 words
A powerplant as claimed in one of the foregoing Claims, characterized by the fact that said current generator (7) is also designed to operate as an electric motor; said second drive (6) presenting a third clutch (5a) designed to assume a first position wherein said shaft (5) connected to said rotor element of said current generator (7) is also connected to said drive line (3), and a second position wherein said shaft (5) is disconnected from said drive line (3).
Claim 4
Dependent Claim
25 words
A powerplant as claimed in one of the foregoing Claims, characterized by the fact that said first (11) and second (6) drives are gear drives.
Claim 5
Dependent Claim
31 words
A powerplant as claimed in one of the foregoing Claims, characterized by the fact that said first drive (11) is connected to said drive line (3) upstream from said transmission (2).
Claim 6
Dependent Claim
35 words
A powerplant as claimed in one of the foregoing Claims from 1 to 4, characterized by the fact that said first drive (11) is connected to said drive line (3) downstream from said transmission (2).
Claim 7
Dependent Claim
36 words
A powerplant as claimed in one of the foregoing Claims, characterized by the fact that said second clutch (12) is located between said rotor element of said electric motor (10) and said first gear drive (11).
Claim 8
Dependent Claim
36 words
A powerplant as claimed in one of the foregoing Claims, characterized by the fact that it comprises a third drive (2a) for connecting said transmission (2) to said shaft (5) providing for said power takeoff (9).
Claim 9
Dependent Claim
44 words
A powerplant as claimed in one of the foregoing Claims, characterized by the fact that said electric motor (10) is also designed to operate as a current generator, for electrically braking said vehicle and generating electric current which is supplied to said battery (8).
