The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
Before describing the utility model in detail, need to prove that in fact alleged tire in the utility model should comprise wheel rim, spoke etc.When mounted, the bolt hole on the spoke is aimed at the wheel bolt on the wheel hub, be set on the wheel hub then and fastening nut, can accomplish fitting of tire.
Engaging accompanying drawing below is elaborated to the utility model.
The utility model at first provides a kind of replacing method of motor tire, and this method comprises: step 1: utilize jacking system to make used tire liftoff automobile jack-up; Step 2: used tire is pulled down from wheel hub; Step 3: air bag is put into the position below the wheel hub; Step: 4: new tire is put on the air bag; Step 5: utilize source of the gas to give airbag aeration, make new tire be elevated to the position of wheel hub; Step 6: the new mounting of tyre that will raise is to wheel hub.
By this method, can be dexterously the gas of motor tire or Automobile air brake system be filled in the air bag through appendix, air bag is heaved, be elevated to the position of wheel hub with the tire above the air bag, therefore easy to operate, simple in structure.
Particularly, as shown in Figure 1, when changing motor tire, at first utilize lifting tool 2 such as jack with automobile jack-up one side jack-up of automobile (normally with), used tire is pulled down from wheel hub 1.In Fig. 1, used tire is pulled down, and in Fig. 1, does not show.In addition, what show among Fig. 1 is the twin tire structure, promptly on each wheel hub 1 two tires is installed.
Next, as shown in Figure 2, with air bag 3 be taped against wheel hub 1 below, then new tire to be installed (for example spare tyre) 4 is placed on the air bag 3.Preferably, can new tire 4 be rolled on the air bag 3 artificially, more laborsaving, convenient.The inflation inlet of the expression of 31 among figure air bag.
As shown in Figure 3; During position below new tire 4 is rolled into wheel hub 1; One end of appendix 5 is connected on the inflation inlet 31 of air bag 3, and the other end with appendix 5 for example is connected on the tire tube valve 41 of new tire 4 through charge valve 6 then, opens the operating handle 61 on the charge valve 6 then; High pressure gas in the new tire 4 will fill in the air bag 3 through appendix 5, and air bag 3 is heaved.
As shown in Figure 4, along with the gas in the new tire 4 constantly charges in the air bag 3, air bag 3 will raise with top new tire 4; Until the position relative with wheel hub 1; The shutoff operation handle 61 then, stop inflation, and the bolt hole on the new tire 4 is aimed at the wheel bolt of wheel hub 1; New tire 4 is set on the wheel hub 1, and fastening nut gets final product then.At last, charge valve 6 is pulled down from tire tube valve 41, opening operation handle 61 discharges the gas in the air bag 3.
Therefore, through said method, new tire 4 can be installed easily.The unloading process of used tire can adopt operated in accordance with conventional methods, and the utility model is explanation no longer separately.
In the utility model, can use new tire 4 for air bag 3 gas filed sources of the gas, gather materials on the spot, easy to operate.Certainly, if the used tire of pulling down has enough air pressure, also can use used tire to give air bag 3 inflations.In addition, as a kind of selection, can also use along with other sources of the gas that carry, the for example air braking system of automobile.For example, can get gas from the air receiver of air braking system.
Fig. 5 has shown the more changing device of the motor tire of the utility model.As shown in Figure 5; The utility model provides a kind of more changing device of motor tire; This more changing device comprise air bag 3, appendix 5 and charge valve 6, an end of said appendix 5 can be connected on the inflation inlet 31 of air bag 3, the other end can be connected to source of the gas through charge valve 6.
As indicated above, the source of the gas that the utility model uses can be used tire to be replaced, new tire to be installed or the air braking system of automobile.
