Refer to Fig. 1 and Fig. 2, the air inlet system for vehicle of the present embodiment, comprise admission line (scheming not shown), the air-strainer 11 be communicated with admission line, the throttle valve body be communicated with described air-strainer 11 or Carburetor 12, also comprise a resonant cavity 13, described throttle valve body or Carburetor 12 are communicated with described air-strainer 11 by described resonant cavity 13.Be provided with a suction port and an air outlet at described resonant cavity 13, described suction port is communicated with described air-strainer 11 by a connecting tube 14, and described air outlet is communicated with described throttle valve body or Carburetor 12 by an outlet pipe (scheming not shown).Particularly:
In the present embodiment, described resonant cavity 13 is a housing with internal cavities, and housing is roughly in rectangular shape.The both sides of housing are provided with two mounting ears 131, two mounting ears 131 are respectively equipped with and install earhole 132 for two of being arranged on by resonant cavity 13 on vehicle frame.When mounted, two construction bolts are each passed through two and install earholes 132 and vehicle frame to carry out installations fixing, and resonant cavity 13 is installed on the vehicle frame that is positioned near motor the most at last.
In the present embodiment, the suction port of described resonant cavity 13 and air outlet are located near air-strainer 11 with near the throttle valve body of vehicle or the one side of Carburetor 12 respectively, in order to facilitate the installation of connecting tube 14 and outlet pipe.
For the ease of the quick mounting of connecting tube 14, the air inlet system for vehicle of the present embodiment also comprises an air inlet tube head 15, the first end of described air inlet tube head 15 can be one-body molded with described suction port, also can with resonant cavity 13 bonding forming, the second end of described air inlet tube head 15 is communicated with the second end of described connecting tube 14 and coordinates.
In the present embodiment, the two ends of described connecting tube 14 have a circular groove 142 held tightly for anchor ear respectively, on the tube head that the first end ring set of connecting tube 14 is arranged on air-strainer 11, anchor ear is encircled and tightens up and seal action to play on the circular groove 142 of this first end.Second end ring of connecting tube 14 is enclosed within air inlet tube head 15, is tightened up and seal action by an other anchor ear ring on the circular groove 142 of the second end to play.In other examples, the mode that described connecting tube 14 also adopts rotation to tighten is carried out installation with described air inlet tube head 15 and is coordinated, and adopts above-mentioned mounting type to save the installation time, the second end convenient disassembly of connecting tube 14.Understandable, described connecting tube 14 can also have different changes from the connection fastening methods between resonant cavity 13 and air-strainer 11, describes in detail no longer one by one herein.
For the ease of the quick mounting of outlet pipe, the air inlet system for vehicle of the present embodiment also comprises a tube head 16 of giving vent to anger, the first end of described tube head 16 of giving vent to anger and the air outlet of described resonant cavity 13 one-body molded, described in give vent to anger the second end of tube head 16 be communicated with one end of described outlet pipe and coordinate.The mode that described outlet pipe can adopt rotation to tighten is carried out installation with described tube head 16 of giving vent to anger and is coordinated, and same, the mode that described outlet pipe can also be held tightly by above-mentioned anchor ear is carried out installation with tube head 16 of giving vent to anger and coordinated.Adopt above-mentioned mounting type, save the installation time, outlet pipe convenient disassembly.In other examples, one end of described outlet pipe can directly fixedly be communicated on resonant cavity 13, and one end is directly communicated with the throttle valve body of vehicle or Carburetor 12 in addition; Or the two ends of outlet pipe are communicated with throttle valve body or Carburetor 12 with resonant cavity 13 respectively by two tube heads.
In the present embodiment, described resonant cavity 13 is also provided with one for the reserved tube head 17 that is communicated with the motor of vehicle by waste gas circulation pipeline or preformed hole.Described reserved tube head 17 is located at the one side near motor on resonant cavity 13, its Main Function is the effect playing a waste gas circulation utilization, in-engine waste gas flows to resonant cavity 13 by circulating line, to be flowed through after throttle valve body or Carburetor 12 again in flow direction engine by resonant cavity 13.When some vehicles do not need this function, this reserved tube head 17 or preformed hole can be blocked.
In the present embodiment, described connecting tube 14 is positioned near engine cylinder-body, connecting tube 14 is generally sebific duct, during motor long-play, engine block temperature is very high, and connecting tube 14 affects by cylinder temperature, yielding when air-intake negative-pressure is larger, the tube wall of connecting tube 14 flattens inwards, make the channel narrows that air enters, reduce air inflow and overall efficiency.Therefore, connecting tube 14 can be arranged stiffening rib 141 to increase the intensity of connecting tube 14.And in the present embodiment, stiffening rib 141 is two, they are arranged on the inwall of pipeline along the length wise of pipeline, particularly, two stiffening ribs 141 are located at the both sides of inwall relatively, if two pipelines extend respectively to relative direction, then they form an extended surface, if connecting tube 14 is circular pipe, so connecting tube 14 cuts open by this extended surface from the length direction of connecting tube 14 is the semi-circle pipe of two identical radian measure, if connecting tube 14 is square pipe, so two stiffening ribs 141 are symmetrically set on two relative sides.In other examples, described stiffening rib can also arrange one.In the present embodiment, stiffening rib 141 can shaping at connecting tube 14 be one-body molded, it makes simple.
Stiffening rib 141 is so arranged, strengthen the intensity of connecting tube 14 on the one hand, greatly reduce connecting tube 14 because of high temperature, the situation of easily flatten inwards when air-intake negative-pressure is larger, being out of shape, shunting action is played to charge air flow, the noise produced when reducing air inlet on the other hand.
The utility model embodiment, increases the resonant cavity 13 of a cavity structure in air-strainer 11 rear end, can when air velocity, flow are large stored air, at air velocity, flow hour release air, play balanced action, improve car load stable working, thus improve car load travelling comfort; Avoid air in original structure and flow directly into Carburetor 12 or throttle valve body and the intake resistance caused and the problem such as noise is larger; Resonant cavity 13 is remained for the reserved tube head 17 that is communicated with the motor of vehicle by waste gas circulation pipeline or preformed hole in advance, in-engine waste gas flows to resonant cavity 13 by circulating line, to flow through after throttle valve body or Carburetor 12 again in flow direction engine by resonant cavity 13, play the effect of a waste gas circulation recycling, when some vehicle does not need this function, this preformed hole or reserved tube head 17 can also be blocked, make automobile vendor have more selection; Stiffening rib 141 is set at connecting tube 14 inwall, also shunting action is played to charge air flow while strengthening connecting tube 14 intensity, the noise produced when reduce further air inlet.
These are only mode of execution of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
