Abstract
We produced a test LRV (Light-Rail-Vehicle) running only by the on-board storage electric energy between tram stops, and experimented on a newly set test truck. This vehicle has 3 pair of 2 independent wheels mounted on a load equalizer (by linkds) type of bogie with steering mechanism, and each wheel is driven by an electric motor. The wheel gauge is set as 1,067mm, suitable to an experiment running on the conventional truck lines in Japan. The loop truck has a 472.101m length, 85‰ maximum gradient, 5m minimum radius, and there are some complex points with varying gradient and curve. These features are applicable to the experimental simulation under the severe condition in case on the city streets. The vehicle has high performance Electric Double Layer Capacitor (EDLC) with charge balancing circuit on board, and is fed by the supply terminals equipped in an every tram stop, within a boarding and alighting time. So, this vehicle needs no overhead feeder line and no kind of feeder rail (third rail). Now, we continue to carry out tests and get the experimental data of the running distance per one charge, the powering and braking performance, and the running stability, which will be utilized to the commercial vehicle design.
