Abstract
Abstract In order to make an automotive engine universally applicable for a 2- or for 4-wheel drive, for mounting forwards or in the rear, and with its axis longitudinally or transversely, a gas turbine provided with at least two turbine rotors is used. The rotors are interconnected by means of a transmission and are further connected to a torque divider having two output shafts. One of these output shafts is arranged to pass through a hollow shaft in the rotor/transmission system, thus making possible the driving of wheels located to opposite sides of the engine.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
In a universal automotive engine for use in driving two pairs of wheels, a gas turbine including a gas producing part and at least two rotors, transmission means for transferring power between the rotors in an integral system, a torque divider connected to said rotors and having two output shafts, at least one hollow shaft in the transmission means, and means for mounting one of said output shafts within said at least one hollow shaft, in which the torque divider is defined by a differential provided with bevel gears, one of the output shafts being displaced with respect to the geometrical axis of the adjacent pair of wheels to permit the other output shaft to pass through said hollow shaft and above the geometrical axis of said pair of wheels.
Claim 2
Dependent Claim
130 words
In a universal automotive engine for use in driving two pairs of wheels, a gas turbine including a gas producing part and at least two rotors, transmission means for transferring power between the rotors in an integral system, a torque divider connected to said rotors and having two output shafts, at least one hollow shaft in the transmission means, and means for mounting one of said output shafts within said at least one hollow shaft, in which the torque divider is defined by a differential provided with bevel gears, one of the output shafts being displaced with respect to the geometrical axis of the adjacent pair of wheels to permit the other output shaft to pass through said hollow shaft and above the geometrical axis of said pair of wheels.
Claim 3
Dependent Claim
156 words
In a universal automotive engine for use in driving two pairs of wheels, a gas turbine including a gas producing part and at least two rotors, transmission means for transferring power between the rotors in an integral system, a torque divider connected to said rotors and having two output shafts, at least one hollow shaft in the transmission means, means for mounting one of said output shafts within said at least one hollow shaft, and a third turbine rotor driving a compressor of the gas producing part, in which the torque divider is defined by a planetary gear having one output shaft connected to a reversing gear at the adjacent pair of wheels, while the other output shaft forms part of the transmission means to the compressor rotor system and continues through a hollow shaft in said part of the transmission means as a driving shaft to the pair of wheels located remotely from the engine.
Claim 4
Dependent Claim
156 words
In a universal automotive engine for use in driving two pairs of wheels, a gas turbine including a gas producing part and at least two rotors, transmission means for transferring power between the rotors in an integral system, a torque divider connected to said rotors and having two output shafts, at least one hollow shaft in the transmission means, means for mounting one of said output shafts within said at least one hollow shaft, and a third turbine rotor driving a compressor of the gas producing part, in which the torque divider is defined by a planetary gear having one output shaft connected to a reversing gear at the adjacent pair of wheels, while the other output shaft forms part of the transmission means to the compressor rotor system and continues through a hollow shaft in said part of the transmission means as a driving shaft to the pair of wheels located remotely from the engine.
Claim 5
Dependent Claim
53 words
The automotive engine according to claim 2, in which the reversing gear is adapted to transfer torque for backwards movement to the adjacent pair of wheels only, with the other output shaft to the remotely located pair of wheels issuing from said part of the transmission system being provided with a disengageable clutch.
Claim 6
Dependent Claim
27 words
An automotive engine according to claim 2, in which the torque divider is defined by a stepped gear providing different amounts of torque to the output shafts.
