The invention relates to a self-supply pneumatic vehicle, in particular to a self-supply pneumatic vehicle capable of supplying consumed compressed gas in the running process. At present, traffic tools at home and abroad are diverse, and the power is sourced from
gasoline, diesel oil,
liquefied petroleum gas,
natural gas or storage batteries, so that the cost is high,
pollution is generated to the environment, and more fundamentally, the energy is limited. An
electric vehicle does not use
fuel oil and is environmentally-friendly, but the
core energy part of the
electric vehicle is a storage battery which has low capacity and needs frequent charging, and the rejected storage battery causes environmental
pollution. The self-supply pneumatic vehicle comprises an
air compressor, a gas
storage tank, a
pneumatic motor, a worm wheel-worm mechanism, a
clutch, a speed change device, a variable-energy speed change device, a generator and a storage battery. The self-supply pneumatic vehicle has a reasonable structure; and the adopted
pneumatic motor does not consume
gasoline, diesel oil,
natural gas or other gases, so that the pneumatic vehicle has no
pollution to the environment and is efficient and energy-saving. The gas
storage tank is charged along running and can continually work, so that the pneumatic vehicle has long running distance.
