Abstract

The utility model relates to a tyre inflating self-service device for vehicles without an air pump. A mix gas cut-off valve and a pure air inlet are additionally arranged on one of the air intake branch of a multi-cylinder engine, and an air outlet pipe joint is also processed. Compressed air generated by the cylinder of the air intake branch enters a tyre through the air outlet pipe joint, and therefore, vehicles can have an inflation function.

Description

No air pump automobile tyre inflation self-help apparatus

The utility model relates to a kind of no air pump automobile tyre inflation self-help apparatus.

At present, most homemade or imported autos all are not equipped with inflation pump.Early stage cross country car once was equipped with air pump air reservoir device, was used for brake function, also provided convenience for travel tyre during inflation of field.Car steam in the recent period in order to improve the brake system sensitivity, reduce noise, energy-conservation and loss of weight increase-volume, all adopt water brake, cancelled the air pump system, therefore, in long-distance driving process, particularly in work such as bicycle field work, geoexploration,, will bring great difficulty and trouble to the driver and conductor in case tire, spare tyre go wrong.

The purpose of this utility model is for no air pump automobile provides a kind of Tire Inflation System, can utilize equipment of itself to give inflation of tire when it is travelled in the open air, realizes the purpose of saving oneself.

The technical solution of the utility model is: the carburettor at multicylinder car installs a mixture gas shutoff valve and a pure air inlet additional to a certain air intake branch between cylinder, pure air inlet and is processed a standby freeing pipe joint between cylinder and mixture gas shutoff valve.When needing to give inflation of tire, close the mixture gas shutoff valve, open pure air inlet, extract corresponding light-up plug, install freeing pipe joint and inflation leather hose.Behind the engine starting, utilize other cylinder actings of not repacking, drive the modified cylinder pistons work, produce pressurized air, pressurized air is discharged from the freeing pipe joint, enters tire by the inflation leather hose.

The effect of mixture gas shutoff valve and pure air inlet is to guarantee that charge air conditioning is a pure air, in order to avoid the corrosion damage tire.

The utility model has solved the automobile field tyre during inflation difficult problem of travelling effectively, and easy for operation, processing is simple, only needs make improvements slightly on former machine, and general automaker can both carry out; Lower than being equipped with the inflation pump cost separately; Both avoided shortcomings such as early stage automobile air pump air reservoir device volume is big, Heavy Weight, idle output is big, noise is big, and increased again and inflated the function of saving oneself; Charge efficiency height (can substitute the bad for the good in 3-5 minute) as the 750-16 tire; To the vehicle zero damage.This technology can be widened on all power actuated vehicles and use.

Accompanying drawing 1 is air intake branch repacking schematic cross-section, and mixture gas shutoff valve (1) is made up of valve (4), control driving lever (5) and packing seal (6) etc.Pure air inlet (2) is made up of air inlet Luo pipe (7), cap (8), filtration sponge (9) and packing seal (6) etc.

Accompanying drawing 2 is a freeing pipe joint scheme drawing, and its a end is complementary with light-up plug Luo hole, and the b end connects the inflation leather hose.

Be example with the quadruple cylinder engine below, working process and principle be described:

For four scarce driving engines, consider driving engine order exhaust acting process, mixture gas shutoff valve and pure air intlet are installed on the 3rd cylinder air intake branch.When tire need be inflated, parking of automobile was hung neutral, close mixture gas shutoff valve (1) to end mixture gas, open pure air inlet cap (8), back out the 3rd cylinder light-up plug, set up freeing pipe joint (3) and inflation leather hose, start the engine, 1st, 2,4 cylinders acting drives the 3rd cylinder piston and produces pressurized air, and pressurized air is discharged from the 3rd cylinder freeing pipe joint (3), enter tire through the inflation leather hose, begun inflation work.Inflation finishes, and covers tight pure air inlet cap (8), opens mixture gas shutoff valve (1), takes off freeing pipe joint (3), sets up light-up plug, and automobile recovers the cruising state.

The opening and closing of mixture gas shutoff valve and pure air inlet also can be designed to by a transfer device interlock control.

Claims

A kind of no air pump automobile tyre inflation self-help apparatus, it is characterized in that: it is formed by being installed at mixture gas shutoff valve on a certain air intake branch of automotive engine and pure air inlet and a standby freeing pipe joint, pure air inlet is between cylinder and mixture gas shutoff valve, and the freeing pipe joint inserts the corresponding light-up plug jack of repacking branch road.
