The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail:
As Fig. 1, shown in Fig. 2 and Fig. 3, a kind of gas circuit structure of central air-charging and air-discharging system, it comprises a kind of gas circuit structure of central air-charging and air-discharging system, it comprises wheel hub 2, steering swivel 1 is installed in wheel hub 2, in the side end face of wheel hub 2, be provided with end cap 7, between end cap 7 and steering swivel 1, form cavity 8, between steering swivel 1 and wheel hub 2, be respectively equipped with seal ring 9 and seal ring 10, on described steering swivel 1, have air flue II stationary part 5 and air flue I stationary part 4, on wheel hub 2, have air flue I rotating part 3, on end cap 7, have air flue II air extractor duct 6, wherein, air flue II stationary part 5 and air flue II air extractor duct 6 are all communicated with cavity 8, air flue I rotating part 3 and air flue I stationary part 4 are communicated with seal ring 10 respectively.
On described steering swivel 1, have air flue I stationary part 4, wheel hub 2 has air flue I rotating part 3, and wherein air flue I stationary part 4 and air flue I rotating part 3 are all communicated with seal ring 9.
In the assembly of wheel limit, realize two air flues from static to motion.Article one, the air flue from static to motion: air flue enters from static steering swivel 1, i.e. air flue I stationary part 4, between steering swivel 1 and wheel hub 2, two seal ring II of symmetrical installation establish air flue hole and are communicated with air flue I stationary part 4 in the middle of seal ring II.Between 2, two seal ring II of wheel hub, air flue I rotating part 3 is set, like this, even steering swivel 1 rotation relative to wheel hub 2, air flue I stationary part 4 still can communicate with air flue I rotating part 3, forms an air flue from static to motion.The air flue of second from static to motion: air flue enters from steering swivel 1, it is air flue II stationary part 5, it directly leads to cavity 8, cavity 8 has end cap 7, steering swivel 1, wheel hub 2, seal ring I, seal ring II to form, on end cap 7, set up air flue II air extractor duct 6, the end cap 7 at air flue II air extractor duct 6 and its place is with relative rotation between wheel hub 2 and steering swivel 1, the common air flue of second from static to motion that form of air flue II stationary part 5, cavity 8 and air flue II air extractor duct 6.Two seal rings 9 and 10 will have certain air seal function.
The effect of Center Tyre Inflation/Deflation System be exactly vehicle advance or stopped process in regulating wheel tire pressure, realize tyre inflating, venting and pressure measurement operation, when system is not worked, want to realize tyre pressure-keeping.Fig. 2 is that double air passage wheel limit assembly structure incorporates the schematic diagram of gas circuit that Center Tyre Inflation/Deflation System realizes tyre pressure-keeping state.In figure, 12,13,15 3 electromagnetic valves are all in initial condition (not powering state), and gas control normally closed switch valve 11 is in normally off, tyre pressure-keeping.
Fig. 5 is that double air passage wheel limit assembly structure incorporates the schematic diagram of gas circuit that Center Tyre Inflation/Deflation System realizes tyre inflating state.15 energisings of two-bit triplet electromagnetic valve, high pressure gas lead to air flue II stationary part 5 from source of the gas 14, then lead to air flue II air extractor duct 6, and high pressure gas promote gas control normally closed switch valve 11, make it from normally off, turn to conducting state.Live switch electromagnetic valve 12 energisings simultaneously, this electromagnetic valve changes closed condition as shown in Figure 3 into from normal open state.Normally closed switch electromagnetic valve 13 energisings simultaneously, this electromagnetic valve changes conducting state as shown in Figure 3 into from normally off.High pressure gas lead to air flue I stationary part 4 from source of the gas 14, then lead to air flue I rotating part 3, then through control normally closed switch valve 11, lead to tire.Realization is to tyre inflating.
Fig. 6 is that double air passage wheel limit assembly structure incorporates the schematic diagram of gas circuit that Center Tyre Inflation/Deflation System realizes the state that bleeds a tire.15 energisings of two-bit triplet electromagnetic valve, high pressure gas lead to air flue II stationary part 5 from source of the gas 14, then lead to air flue II air extractor duct 6, and high pressure gas promote gas control normally closed switch valve 11, make it from normally off, turn to conducting state.Gas in tire leads to air flue I rotating part 3 through gas control normally closed switch valve 11, then leads to air flue I stationary part 4, through normally closed switch electromagnetic valve 13, discharges.Live switch electromagnetic valve 12 and normally closed switch electromagnetic valve 13 equal no power, in a state of nature position.Thereby realize, deflate a tire.
Fig. 7 is that double air passage wheel limit assembly structure incorporates the schematic diagram of gas circuit that Center Tyre Inflation/Deflation System realizes tire pressure measurement state.15 energisings of two-bit triplet electromagnetic valve, high pressure gas lead to air flue II stationary part 5 from source of the gas 14, then lead to air flue II air extractor duct 6, and high pressure gas promote gas control normally closed switch valve 11, make it from normally off, turn to conducting state.Gas in tire leads to air flue I rotating part 3 through gas control normally closed switch valve 11, then leads to air flue I stationary part 4, and with pressure sensor 16 conductings, Live switch electromagnetic valve 12 energisings simultaneously, are converted to closed condition from normal open state, blanketing gas.Normally closed switch electromagnetic valve 13 no powers, in a state of nature position confining gas.Realize measure tire pressure.
The inflation of Center Tyre Inflation/Deflation System, venting, pressure measurement and four kinds of operating modes of pressurize can realize by controlling three electromagnetic valves conversion and the maintenance of any operating mode.
The wheel limit two gas circuit structures of assembly are simple, can significantly reduce the design difficulty of other parts of Center Tyre Inflation/Deflation System, improve the reliability of whole system.
