Abstract

A gas turbine for the drive of motor vehicles which includes a free output turbine adapted to be connected during braking with the compressor by way of a hydrostatic force-transmitting system consisting of a pump and of a motor, that is adapted to be selectively engaged and disengaged by filling and emptying the circulatory system thereof.

Claims

1. A braking arrangement for a motor vehicle driven by a turbine engine of the type having a rotatable compressor means and a rotatable work turbine means, said work turbine means being independently rotatable with respect to said compressor means during normal drive of the vehicle, said work turbine means being in driving engagement with an output shaft for driving said vehicle;

said arrangement comprising;

selectively engageable braking transmission means for transmitting braking forces from said compressor means to said work turbine means, and a selectively actuable brake control means for controlling the engagement of said transmitting means wherein said braking transmission means includes a hydrostatic coupling means for coupling said compressor means with said work turbine means only when said brake control means is actuated.

2. A braking arrangement according to claim 1, wherein said hydrostatic coupling includes a pump means, a motor means, a circulatory system operatively connecting said pump means and said motor means and means responsive to the actuation of said brake control means for filling and emptying said circulatory system for selectively engaging and disengaging said pump and motor.

3. A gas turbine according to claim 2, further including gear means for connecting said work turbine means with said pump and gear for connecting said means compressor means with said motor means.

4. A gas turbine according to claim 3, wherein each of said gear means consists of a pair of spur gears providing a speed reduction from said work turbine means and compressor means to said braking transmission means.

5. A gas turbine according to claim 4, wherein said means for filling and emptying said circulatory system includes a slide valve means for selectively connecting said circulatory system with a tank.

6. A gas turbine according to claim 5, wherein said slide valve means operably connects said pump means with a feed line from said tank during braking and with a discharge line during normal operation when the braking is terminated.

7. A gas turbine according to claim 6, wherein said means for filling and emptying said circulatory system further includes means for electromagnetically actuating said slide valve means.

8. A gas turbine according to claim 7, wherein said brake control means includes a brake pedal, said slide valve means being actuated in dependence on the position of said brake pedal.

9. A gas turbine according to claim 2, wherein said means for filling and emptying of said circulatory system includes a slide valve means for selectively connecting said circulatory system with a tank.

10. A gas turbine according to claim 9, wherein said slide valve means operably connects said pump means with a feed line from said tank during braking and with a discharge line during normal operation when the braking is terminated.

11. A gas turbine according to claim 9, wherein said means for filling and emptying said circulatory system further includes means for electromagnetically actuating said slide valve means.

12. A gas turbine according to claim 9, wherein said brake control means includes a brake pedal, said slide valve means being actuated in dependence on the position of a brake pedal.
