Abstract

The utility model relates to an automatic power assisting air environment protecting pneumatic vehicle, which comprises a vehicle body, a running mechanism, an operating mechanism, a pneumatic engine, a gas storing tank and a gas exhausting pipe. The utility model is characterized in that an automatic power assisting device is also arranged on a chassis of the vehicle body. Two gas cylinders are arranged in the power assisting device, a bent shaft is arranged in each of the gas cylinders and is connected with a rotary shaft of an engine or a main shaft of a rear wheel through a leather belt and two connecting rods are arranged on the bent shaft. One end of each of the connecting rods is connected with a piston, when the pneumatic vehicle runs, the bent shaft can drive the piston to make reciprocating movement through the connecting rods to generate high pressure gas. A gas source is replenished to the gas storing tank through an automatic valve and a gas supplying pipe, and the pneumatic vehicle does not burn petrol or gas and also does not use a storage battery as power. High pressure air is only used for pushing a vane of the engine to rotate in order to drive a car to run, so the utility model has no pollution of environment, has no injury for a human body and can overcome the defects that the gas source in the gas storing tank of the existing pneumatic vehicle is consumed fast and is filled with gas by a special gas filling station, with need of frequent parking, etc. The service life of the gas source in the gas storing tank can be prolonged, the vehicle trip is increased and the utility model is suitably used as the car and is particularly used as the car in a city.

Description

A kind of air environmental protection railcar of autoamtic boosting

[technical field]

The utility model relates to a kind of automobile, is a kind of air environmental protection railcar of energy autoamtic boosting specifically.

[background technology]

As everyone knows, present automobile power is mainly derived from gasoline, diesel oil, oil liquefied gas or storage battery, because burns gasoline diesel oil or blue gas, not only the cost height also will produce environment and pollute, to people's health generation infringement; With the battery-driven car of storage battery, because the capacity of storage battery is little, need often charging, the speed during operation is slow, and hill climbing ability is poor, not too is fit to long-distance operation.On October 22nd, 2003, disclosed a kind of CN2581228Y that is numbered, name is called the utility model patent of air environmental protection railcar, employing be that air directly promotes the piston work done, not oil firing, vapour are also without storage battery.It can be the revolution of automobile power.Through repeatedly trying out of the inventor, find that the consumption of air source in the storage tank is very fast, need in the long-distance driving to put on the air to special gas-filling station, the one, inflation needs some times of waste, the 2nd, need establish a plurality of gas-filling stations on the way, and establish the condition of this gas-filling station at present is that all right when ripe, therefore influence the operation and the sale of railcar easily.

[summary of the invention]

Fast for the consumption of air source that overcomes existing railcar storage tank, limited the ability of the long-distance operation of this railcar, the utility model provide a kind of can be automatically in automotive operation to the air environmental protection railcar of the gas filed autoamtic boosting of storage tank.To reduce gas filed number of times in the driving, increase the stroke of railcar.

For solving its technical matters, the technical scheme that the utility model adopted is: on the existing air railcar that comprises vehicle body, traveling gear, air motor, expansion box, freeing pipe, have additional a motor-driven assistor; The bent axle of this motor-driven assistor links to each other with the axletree of automobile by belt or chain, be provided with connecting rod in the crank slot of bent axle, one end of connecting rod links to each other with piston, and during crankshaft revolution, connecting rod drives piston and make back and forth movement in cylinder, the top of cylinder is provided with automatic valve, link to each other with expansion box by tracheae, as long as automotive operation, the autoamtic boosting case is just constantly inflated in expansion box, make the interior source of the gas of expansion box constantly obtain some and replenish, prolong the period of service of expansion box source of the gas.

On the wheel hub of the utility model railcar, a 12V dynamotor is housed, the mouth of this electrical generator is connected on the charging electrode of storage battery on the car.In the car running process, this generating is motor-driven constantly charges to the storage battery of establishing onboard, and the electrical equipment electricity consumption such as illumination, loudspeaker, sound equipment of gas car is provided with the electric energy of storage battery.

The beneficial effects of the utility model are: 1. because the utility model is provided with the autoamtic boosting case, can constantly put on the air to expansion box automatically in automotive operation, replenish a part of source of the gas, make the source of the gas in the case prolong its service life, reduce gas filed number of times in the way.Through design, travel 200 kilometers and can not need to inflate midway with this railcar.2. of the present utility model simple in structure, cost is low, and is easy to manufacture, and stroke is far away, and the stronger market competitiveness is arranged.3. not combustion oil, vapour of the utility model is also without storage battery.Therefore environment not being polluted, the people is stopped healthy not infringement, only promote the piston work done with high pressure air, is a kind of comparatively ideal environmentally friendly machine.
