Patent ID: 7705501

Claim:
A dual parallel electro-mechanical structure with a coaxial input/output (I/O), comprising two rotation parts each including a rotating electro-mechanical unit, the electro-mechanical units being arranged in parallel and having drive force outputs that are made coaxial by means of a transmission disposed on each side of a common structure supporting said electro-mechanical units, the common structure being adapted to be situated between two wheels to mitigate the impact when wheels on either side are subject to force, wherein: a first of the electro-mechanical units includes at least one first electro-mechanical field structure; at least one second electro-mechanical rotation part structure; and a first bearing for an output of the electro-mechanical unit, a drive force of said first electro-mechanical unit being output through a first transmission and a first output axle, a second of the electro-mechanical units including at least one second electro-mechanical rotation part structure; at least one second electro-mechanical magnetic field structure; and a second bearing for an output of the second electro-mechanical unit; and at least one casing, a drive force of said second electro-mechanical unit being output through a second transmission and a second output axle, wherein: the first transmission is disposed on one side of the first casing to receive the drive force from an output end of the first rotation part structure and to output the drive force through the first output axle supported by the first bearing; the second transmission is disposed on one side of the second casing on a side of the common structure opposite the side on which the first transmission is disposed, the second transmission being disposed to receive the drive force from an output end of the second rotation part structure and to output the drive force through the second output axle that is coaxial with the first output axle and on an opposite side of the common structure from the first output axle.
