Abstract

The utility model relates to hybrid drive for vehicles that significantly decreases the consumption of fuel because it uses a turbine motor (7), which is turned on solely when the charge of the accumulator batteries (3) drops and always works at best rpm. The device increases the distance covered by the vehicle without need for frequent recharge of the batteries from the power supply network. Furthermore, the turbine motor is lighter than the petrol piston engine and in the same time more efficient. The device includes installed accumulator batteries (3) that supply power to at least one electric motor coupled via transmission to the drive wheels of the vehicle, and fuel tank (4) supplying fuel to turbine motor (7) coupled via reducer (11) to generator (6) that is connected to the accumulator batteries. Control unit (9) monitors the charge of the accumulator batteries (3) and turns on and off the turbine motor (7). All six embodiments comprise a device (10) to recharge the accumulator batteries from the power supply network when the driver of the vehicle has access to it.

Claims

1. Hybrid drive for vehicles comprising accumulator batteries that supply power to at least one electric motor connected via transmission to the drive wheels of the vehicle, wherein on the chassis of the vehicle is installed a fuel tank that supplies compressed combustible gas through a gas duct to a pneumatic turbine where the compressed combustible gas expands, wherein the combustible gas is fed from said pneumatic turbine to a turbine motor thereby actuating said turbine motor wherein the turbine motor is connected through a reducer to a generator, which is connected to the accumulator batteries;

and a control unit that monitors the charge of the accumulator batteries and turns on or off the turbine motor.

2. Hybrid drive for vehicles as claimed in claim 1, wherein the tank is for compressed combustible gas.

3. Hybrid drive for vehicles of claim 1, wherein said pneumatic turbine is connected via reducer to the generator.

4. Hybrid drive for vehicles of claim 1, wherein the reducer is incorporated into the generator.

5. Hybrid drive for vehicles of claim 1, further including a device permitting a driver of said vehicle to charge the accumulator batteries from the power supply network.
