Abstract

A dynamo electric machine is connected, over a claw clutch, to the driving wheels of the vehicle; an internal combustion engine is connected over a slip clutch with the shaft of the electric motor, to permit selective drive of the vehicle either electrically, or by the internal combustion engine and, upon suitable interconnection of the dynamo electric machine, simulteneous re-charging of a storage battery when the vehicle is not driven by the dynamo electric machine acting as a motor.

Claims

1. Motor driven conveyance comprising an internal combustion engine (10) having a power output rating in excess of that required to operate the conveyance and having an output shaft (19) forming one end of a power train for the conveyance;

at least one driven wheel (16);

at least one driven wheel axle and a drive shaft connected to said axle (14,

     15) forming one end of the power drive train;

a dynamo electric machine (12) of sufficient power to operate the conveyance, operable in generator mode or in motor mode, and having a double-ended shaft (18, 18'"'"''"'"'), one end (18'"'"''"'"') being directed towards said drive shaft and the other end (18) being directed towards the internal combustion engine shaft (19), said dynamo electric machine forming an intermediate portion of the power drive train;

secondary battery means (17) carried on the conveyance to store power from, and supply power to the dynamo electric machine;

means (13) to selectively and positively either connect, or disconnect, without slip, one end (18) of the dynamo electric machine shaft to the drive shaft and hence directly to the wheel only when the motor conveyance is stopped to place the dynamo electric machine in fixed direct wheel driving connection in the drive train;

means (11) to gradually connect the other end (18) of the shaft of said dynamo electric machine to said internal combustion engine (10), independently of relative motion, or speeds of the shaft (19) of the internal combustion engine (10) and said other end (18) of the shaft of the dynamo electric machine (12);

said gradual connection means (11) being independent of said positive connection means (13) to permit connection of said positive connection means and hence positive drive connection from the dynamo electric machine (12) directly to the wheel upon energization of the dynamo electric machine (12) and moving of the conveyance with the internal combustion engine (10) stopped, and then gradual connection of the internal combustion engine and hence starting of the internal combustion engine during such motion of the vehicle and during operation of the dynamo electric machine.

2. Conveyance according to claim 1, wherein the selective positive connection means (13) is a claw clutch.

3. Conveyance according to claim 1, wherein the gradual connection means (11) is a slip clutch.

4. Conveyance according to claim 1, wherein the dynamo eleCtric machine (12) is a direct current machine.

5. Conveyance according to claim 1, wherein the dynamo electric machine (12) is a multi-phase alternating current asynchronous machine;

and an inverter (25) is provided interconnecting the battery (17) and the asynchronous machine.

6. Conveyance according to claim 1, wherein the double-ended shaft of the dynamo electric machine, the shaft of the internal combustion engine, said selective positive connection means and said gradual connection means, and said drive shaft for the driven wheels are co-planar to provide an in-line drive train, and to locate the rotor of the dynamo electric machine in in-line position within the drive train.

7. Conveyance according to claim 1, wherein the selective positive connection means comprises a claw clutch (13) disconnectable only if the conveyance is stopped and when the dynamo electric machine (12) is stopped.
