Abstract
The utility model relates to an automatic inflating device for a tire. The utility model comprises a casing, an inflation pump and an inflation chamber, wherein, the inflation pump and the inflation chamber are arranged in an inner cavity of the casing fixed to an automobile steel ring. An air duct in which an impeller is arranged on the casing. An impeller shaft is connected with the inflation pump. One end of the inflation pump is communicated with the inflation chamber which passes through the steel ring through an air pipe and is connected with the tire. A piston, a connecting rod and a spring are arranged in the inflation chamber. A piston cavity is communicated with the air duct which can be sealed by the piston. One regulating air nozzle is also arranged on the side wall of the inflation chamber. The automatic inflating device for a tire of the utility model has the advantages of novel structure, convenient, rapid and automatic inflation for the tire, and maintenance of constant atmospheric pressure for the tire. Rollover traffic accidents due to air leakage and tire burst can be prevented.
Description
Technical field
The utility model relates to a kind of automatic tyre air inflation device.
Background technology
Automobile has become the important vehicle in our daily life, along with increasing of automobile quantity, thing followed traffic accident also increases gradually, particularly on express highway, because the speed of a motor vehicle is too fast, when tire pressure is not enough, cause gas leakage easily, in addition blow out, roll-over accident, and to give inflation of tire on express highway also be the very difficult thing of part.
Summary of the invention
The purpose of this utility model just provides a kind of automatic tyre air inflation device that can make tire keep constant air pressure.
Automatic tyre air inflation device of the present utility model comprises housing, inflation pump, plenum chamber, inflation pump, plenum chamber are located in the housing inner chamber, housing is fixed on the Automobile steel ring, and impeller is set on the housing, and paddle shaft links to each other with inflation pump, inflation pump one end communicates with plenum chamber, plenum chamber passes steel ring by tracheae and links to each other with tire, is provided with piston, connecting rod, spring in the plenum chamber, and plunger shaft communicates with air flue, piston can seal air flue, also is provided with one on the plenum chamber sidewall and regulates valve.
The principle of work of motor tire self-filler of the present utility model is: in the middle of the running car, the tire high speed revolution, when the high velocity air of generation is through gas filled device in the steel ring, make the impeller rotation, impeller makes inflation pump work by its axle, to inflating in plenum chamber and the tire, when the air pressure in the tire surpassed setting value, air pressure promoted piston air flue is sealed, impeller stops the rotation, inflation pump quits work, and tire keeps this constant air pressure, during as gas leakage or air pressure decline, the pulling force of spring retracts piston, impeller begins rotation, and tire pressurization is given in inflation pump work.Under special circumstances, can't quit work, make plenum chamber (tire) when internal pressure continues to increase, but regulate the valve automatic deflation to keep the constant air pressure of plenum chamber (tire) as inflation pump.
Motor tire self-filler novel structure of the present utility model, be skillfully constructed, can convenient, fast, automatically give inflation of tire, can avoid because the overturning traffic accident that gas leakage is blown out and produced.
Description of drawings
Accompanying drawing is the utility model structural representation.
