Abstract

The utility model relates to an inflating and deflating device for automobile tyres. The utility model comprises an air source and a pipeline which is provided with an inflating nozzle. The air source is connected with a mode selection switch through the pipeline, one air outlet of the mode selection switch is connected with a barometer, the other air outlet hole of the barometer is connected with the pipeline which is provided with the quick self-sealing inflating nozzle at the end, and the other air outlet of the mode selection switch is communicated with atmosphere. The utility model can be conveniently used for inflating, deflating and detecting automobile tyres. The utility model has the advantages of simple structure, low manufacturing cost and strong reliability; the inflation time for vehicles can be shortened, the labor intensity for operators can be alleviated, and the economy, the safety, the passing ability and the motility of an entire automobile can be enhanced.

Description

Improved motor tire aerating and exhaust device
The utility model belongs to the motor tire aerating and exhaust device, particularly improved motor tire aerating and exhaust device.
According to different road usage conditions, keep suitable tire pressure, to and significant impact all there be service life to the load-carrying capacity of economy, safety and the tire of vehicle itself, cross country car particularly, by changing the size of tire pressure, can also improve the crossing ability and the ride comfort of vehicle greatly.Here it is requires in the vehicle operation process, need frequent to tire put on the air, venting and detecting operation be in the hope of reaching best tire pressure value.
The existing method that charges and discharge gas for motor tire is: inflation of tire hose assembly one end is connected with the air valve of getting of car load brake system, and other end charging connector needs be connected with cranked tire valve, improves engine speed again to accelerate inflationtime.The venting method is: with valve key the spool in the tire valve is depressed, the pressurized air in the tire is discharged, whole deflation course needs manpower all the time the tire tube valve spool to be depressed can.The detected air pressure method is: behind an independently barometric joint and tire valve pinch-off seal, can detect the tire pressure value.
Existing fill, in the deflation course, above-mentioned three kinds of instruments need repeatedly be used alternatingly and just can make tire pressure reach a comparatively suitable atmospheric pressure value, not only the effort and also time-consuming, particularly under rugged environment (as heat, severe cold, sleet sky), above-mentioned work will bring unusual trouble with painstaking to navigating mate, also so often cause tire pressure can not be adjusted to comparatively suitable atmospheric pressure value, thereby cause the tire infantile failure, consumption increase, crossing ability and safety descend.
The device that also has a kind of central authorities to charge and discharge gas is by air compressor, pipeline, maneuver control device, and rotary seal air chamber and various air valve constitute.The maximum characteristics of this device are: no matter automobile all can realize inflation, venting and the detecting operation to tire at stagnation of movement or in travelling.But this system architecture complexity involves great expense, and reliability is relatively poor, and often damages because of the oil sealing of rotary seal air chamber, sealing gland and cause the lubricating oil of vehicle bridge to be scurried in the tire, and vehicle bridge is damaged because of oil starvation, and tire also will be scrapped very soon, causes heavy losses.
The purpose of this utility model is to provide a kind of motor tire central aerating and exhaust device, can give automobile tyre inflation, venting and detecting operation as required easily, and simple in structure, and cost is low, good reliability.Can shorten greatly the charging and discharging the gas time of vehicle, alleviate labor intensity of operating personnel, improve economy, safety, crossing ability and the manoevreability of car load.
The utility model is achieved in that a kind of improved motor tire aerating and exhaust device, comprise source of the gas and the pipeline that charging connector is installed, source of the gas is connected with state selecting switch by pipeline, one of them air extractor duct of state selecting switch connects air-pressure gauge, barometric another air gate is connecting the pipeline that the end is equipped with quick self-sealed charging connector, and another air extractor duct of state selecting switch leads to atmosphere.
When charging and discharging gas to vehicle, after vehicle come to a complete stop, quick self-sealed charging connector of the present utility model is connected good seal with the tire tube valve of the tire that need fill, exit, under this state: a. is if place the inflation shelves with state selecting switch, improve engine speed, put on the air for this tire; B. if state selecting switch is placed venting shelves, the pressurized air in this tire will exhaust to atmosphere, and tire pressure then can descend thereupon; C. if state selecting switch is placed the detection shelves, then the atmospheric pressure value of this tire will be shown by air-pressure gauge.After finishing aforesaid operations, state selecting switch choosing placed detect shelves, quick self-sealed charging connector is taken off to replace from tire valve fix, be initial condition of the present utility model at this moment, vehicle then can cruising.The utility model is simple in structure, and cost is low, and good reliability charges and discharge gas time weak point, has alleviated staff's labour intensity.
Fig. 1 is the structural representation of the utility model embodiment 1
Fig. 2 is the structural representation of the utility model embodiment 2
Below in conjunction with accompanying drawing the utility model is further described, a kind of improved motor tire aerating and exhaust device, comprise source of the gas 1 and the pipeline that charging connector is installed, embodiment 1 as shown in Figure 1, source of the gas 1 is connected with state selecting switch 2 by pipeline, state selecting switch 2 one of them air extractor duct connect air-pressure gauge 3, and another air gate of air-pressure gauge 3 is connecting the pipeline that the end is equipped with quick self-sealed charging connector 4, and another air extractor duct of state selecting switch 2 leads to atmosphere.Embodiment 2 as shown in Figure 2, source of the gas 1 is connected with state selecting switch 2 by pipeline, one of them air extractor duct of state selecting switch connects air-pressure gauge 3 by pipeline, the air gate of air-pressure gauge 3 is by all right connecting bridge select switch 5 of pipeline, another air extractor duct of state selecting switch 2 leads to atmosphere, and the 2-8 of bridge select switch 5 air extractor duct is connecting the pipeline that the end is equipped with quick self-sealed charging connector 4 respectively.Because the vehicle of different driving mode, its vehicle bridge quantity also is not quite similar, so in this device, the quantity of the air extractor duct quantity of bridge select switch and the pipeline that has fast sealing formula charging connector that is attached thereto also should be complementary with the quantity of vehicle bridge.
When using the utility model embodiment 2, after vehicle came to a complete stop, the front axle tyre tire tube valve that quick separately self-sealed charging connector 4 on the pipeline is filled, exits with needs respectively was connected good seal with the back axle tire valve.When needs fill, when exitting, bridge select switch 5 choosing placed the propons shelves to front axle tyre, under this state: a. improves engine speed if state selecting switch 2 is placed the inflation shelves, put on the air for this tire; B. if state selecting switch 2 is placed venting shelves, the pressurized air in this tire will exhaust to atmosphere, and tire pressure then can descend thereupon; C. if state selecting switch 2 is placed the detection shelves, then the atmospheric pressure value of this tire will be shown by air-pressure gauge.When needs to the back axle tire fill, when venting and detecting operation, method of operation is identical with above-mentioned method, just 2 choosings of bridge select switch are placed and detect shelves, after finishing aforesaid operations, quick self-sealed charging connector taken off from each tire valve replace and fix, be the initial condition of this device this moment, and vehicle then can cruising.
