Patent Images
1. A hybrid vehicle comprising:
- first and second axles each with wheels thereon,an IC drive engine,an electric drive motor having a power output of the same order of magnitude of that of the engine,a first transmission means coupled to said first axle and to said drive engine for transmitting drive from the engine to the first axle,a second transmission means coupled to said second axle and to said drive motor for transmitting drive from the motor to the second axle,means including a universal joint shaft connected to said first and second transmission means for transmitting drive therebetween,a first differential connecting said universal joint shaft with one of said transmission means,said first and second transmission means including respective clutches for selectively connecting and disconnecting said drive engine and said drive motor to and from said first and second transmission means respectively, and respective clutch means for selectively connecting and disconnecting said universal joint shaft in driving relation to and from said first and second axles such that either the drive engine or the drive motor alone can selectively drive both of said axles concurrently.

Abstract
A vehicle, more especially in the form of an articulated omnibus, has a hybrid drive system comprising an IC engine and an electric motor, whose power is transmitted not only to an axle driven by the IC engine but in addition to a further drive axle in order to extend the working life of the transmission axles.
