<p>PURPOSE:To absorb part or all of braking power by an engine brake by operating a generator as a motor by reversely converting a converter at the generator side at the braking time. CONSTITUTION:A synchronous generator 2 is coupled with a Diesel engine 1 as an internal combustion engine to supply an AC power to a converter 11 at a generator side. The output of the converter 11 is supplied through a filter reactor 4L, a filter capacitor 4C and GTO inverters 8L, 8R as converters at a motor side to an induction motor 9L coupled with a left wheel and an induction motor 9R coupled with right wheel, respectively. When a traveling vehicle starts being braked, the motors 9L, 9R become induction generators to supply powers through the inverters 8L, 8R and the converter 11 to the generator 1. Thus, the generator 2 becomes the synchronous motor to act an engine brake.</p> |
