Describe according to the vehicle tyre dynamic gas pressure system of the embodiment of the present invention below with reference to Fig. 1.
As shown in Figure 1, according to the vehicle tyre dynamic gas pressure system of the embodiment of the present invention, comprising: pump device 10, caisson 20,Pump air valve 11, the first overflow valve 21, tire 30, magnetic valve 40, wheel valve 31 and ECU 50.
Particularly, pump device 10 is located between the rear suspension and car body of vehicle, is arranged side by side with vehicle shock absorber. When vehicle is expert atCross in journey due to the damper that jolts when compressed pump device 10 also compressed together.
Pump device 10 comprises cylindrical cylinder 12 and is located at the piston 13 in cylinder 12. In the time that pump device 10 is compressed, piston13 start the gas in compression cylinder 12. When the pressure of the interior gas being compressed by piston 13 of cylinder 12 is higher than being connected with pump device 10When pressure in caisson 20, the pump air valve 11 being located between pump device 10 and caisson 20 is backed down, and makes compressed gasEnter in caisson 20 and be stored in storage device 20.
Like this, pump device 10 of the present invention moves back and forth with driven plunger 13 without external connection power source, but passes through pump device 10Be arranged on the impact energy driving pump device of air 10 that can realize between vehicle body and rear suspension by producing in Vehicle Driving Cycle process to gas storageInstall 20 interior inflations, utilize and reclaimed the energy being wasted from dividing, reach the object of saving energy consumption of vehicles. In addition, by pump device10 are located between vehicle body and rear suspension and can additionally take vehicle body space, can not exert an influence to vehicle body layout designs.
Pump air valve 11 is check valve, can ensure that by pump air valve 11 gases at high pressure are filled with in caisson 20, can also prevent simultaneouslyGas in caisson 20 is revealed from pump air valve 11.
Because pump device 10 is along with Vehicle Driving Cycle constantly carries out pump gas, therefore may be also after the preset pressure that arrives caisson 20Continue to the interior pump gas of caisson 20, thereby cause hypertonia in caisson 20 and impaired. Therefore, on caisson 20, establishHave the first overflow valve 21, after the pressure in caisson 20 exceedes the preset pressure of caisson 20, the first overflow valve 21 open withCaisson 20 is carried out to pressure release, when the pressure in caisson 20 drop to its below preset pressure after, the first overflow valve 21 cuts out.
As shown in Figure 1, tire 30 is connected with caisson 20, and magnetic valve 40 is located between caisson 20 and tire 30, works as wheelPressure in tire is less than predetermined pressure, and pressure in caisson 20 is during higher than pressure in tire 30, and magnetic valve 40 is in closingCo-bit puts to be communicated with caisson 20 and tire 30, and caisson 20 is inflated to tire 30.
Wheel valve 31 is located between magnetic valve 40 and tire 30, when the pressure in magnetic valve 40 closures and caisson 20 is greater than tireWhen pressure in 30, wheel valve 31 is backed down so that the gas in caisson 20 is filled with in tire 30.
Wheel valve 31 is check valve, can ensure that by wheel valve 31 gases at high pressure are filled with in tire 30, can also prevent tire simultaneouslyGas in 30 is revealed from gear valve 31.
ECU 50 is connected with magnetic valve 40, and ECU 50 is controlled magnetic valve according to the pressure in each tire and caisson40 closed and disconnected, and then control caisson 20 and inflate to tire 30.
Thus, according to the vehicle tyre dynamic gas pressure system of the embodiment of the present invention, by pump device 10 is located at car body and rear suspension itBetween, not only can by vehicle because of jolt produce impact energy reclaim and be converted into the required driving force of pump gas, saved energy consumption, Er QietongThe control of crossing ECU can ensure that tire, in suitable tire pressure, guaranteed traffic safety. In addition, the vehicle wheel of the embodiment of the present inventionTire dynamic gas pressure system is simple in structure, is convenient to manufacture and maintenance, is suitable for family-sized car and uses.
According to some embodiments of the present invention, as shown in Figure 1, vehicle tyre dynamic gas pressure system also comprises for detection of caisson 20The first pressure sensor 61 of internal pressure and for detection of the second pressure sensor 62 of the internal pressure of tire 30. First, second pressurePower sensor 61,62 is connected with ECU 50 respectively.
After the second pressure sensor 62 detects pressure in tire 30 preset pressure lower than tire 30, control module can be according toThe testing result of one pressure sensor 61 judges whether opens solenoid valve 40, if now the pressure in caisson 20 be greater than tireWhen pressure in 30,50 opens solenoid valve 40 of control module, are filled with in tire 30 gas in caisson 20. When the second pressurePower sensor 62 detects that the pressure in tire 30 reaches after the preset pressure of tire 30, control module 50 shut electromagnetic valves, stop toThe interior inflation of tire 30.
Vehicle tyre dynamic gas pressure system also comprises the second overflow valve 32 being connected with tire 30. Pressure in tire 30 exceedes tire30 preset pressure, can, by with the second overflow valve 32 pressure releases, prevent hypertonia and transition inflation in tire 30.
Vehicle tyre dynamic gas pressure system also comprises the rotary air chamber 70 being located between magnetic valve 40 and wheel valve. Gases at high pressure fill from gas storagePut 20 and flow to the rotary air chamber 70 through core wheel by pipeline and magnetic valve 40, then flow to the air-filled pore in wheel hub by wheel valve 31,Finally be filled with tire 30 from air-filled pore.
In addition, the indoor control panel 80 being connected with control module 50 that is also provided with of vehicle drive, by control panel, 80 drivers can rootAccording to the preset pressure needing in manual adjustments tire 30.
Vehicle according to the embodiment of the present invention is described below.
Comprise the vehicle tyre dynamic gas pressure system described in above-mentioned any one embodiment according to the vehicle of the embodiment of the present invention. Pass through vehicle tyreDynamic gas pressure system can make vehicle fully recycle due to the produced impact energy of jolting, without separately establishing power source with regard to energy for pump deviceEnough real-time inflations realizing tire, be tire always under suitable tire pressure, guaranteed the safety of vehicle, and vehicle of the present inventionSimple in structure, be convenient to manufacture and maintenance.
