Description
Technical field
The present invention relates to automobile technical field, specifically with the gas exhaust manifold of flange arrangement.
Background technique
Manifold is a kind of pipeline structure for automotive air intake, vent systems, can be divided into intake manifold and gas exhaust manifold.Intake manifold is between closure and engine air admittance door, after air enters closure, behind the manifold dsah-pot, air flow channel begins difference, and the quantity of corresponding engine cylinder just has four roads such as four cylinder engines, corresponding five roads of five cylinder engines import air respectively in each cylinder.With NA Naturally Aspirated Engine, because intake manifold is positioned at after the closure, so when engine throttle aperture hour, can't be drawn onto the air of capacity in the cylinder, will cause the mainfold vacuum degree high; And when the engine throttle aperture was large, the degree of vacuum in the intake manifold will diminish.Therefore, spraying the fuel feeding engine all can at pressure meter of intake manifold installing, supply with ECU and judge the engine load, and give an amount of oil spout.And gas exhaust manifold links to each other with engine cylinder, the exhaust of each cylinder is put together import exhaust manifold, pipeline structure that band is disagreed.Requirement to it mainly is to reduce exhaust resistance as far as possible, and avoid phase mutual interference between each cylinder.During the exhaust undue concentration, can produce the phase mutual interference between each cylinder, during namely certain cylinder exhaust, just in time meet other cylinder and alter the next waste gas that does not have emptying.Like this, will increase the resistance of exhaust, and then reduce the output power of motor.Solution is, makes the exhaust of each cylinder as far as possible separately, branch of every cylinder, and perhaps branch of two cylinders, and each branch is lengthened as far as possible and moulding-influence each other with the gas that reduces in the different pipes.In order to reduce exhaust resistance, some racing car adopts Stainless Steel Tube to make gas exhaust manifold.
At present, when gas exhaust manifold is installed, a tightness problem consider exhaust the time, two installations that will consider gas exhaust manifold are fixed and the installation question of the thermal shield that will be connected with gas exhaust manifold, therefore usually easily cause and attend to one thing and lose sight of another, affect the overall performance of gas exhaust manifold.
Summary of the invention
The invention provides the gas exhaust manifold with flange arrangement, solved that the installation of the in the past gentle manifold of tightness of gas exhaust manifold, thermal shield is fixing can not be accomplished goodly simultaneously, and then affect the problem of the overall performance of gas exhaust manifold.
The present invention is that the technical solution problem is achieved through the following technical solutions: with the gas exhaust manifold of flange arrangement, comprise the upper shell and the lower shell body that cooperatively interact, described upper shell comprises upper binding head and a plurality of upper groove, described lower shell body comprises lower union joint and a plurality of lower groove, described upper binding head matches with lower union joint and consists of a connecting head cylindraceous, the quantity of described upper groove equates with the quantity of lower groove, corresponding lower groove of groove on each, and a upper groove and a lower groove consist of an air-flow path, each air-flow path all is communicated with connecting head, the both sides of described upper groove and lower groove are equipped with wing plate, the length of described wing plate is less than the length of upper groove and lower groove, also comprise flange, described flange is provided with a plurality of positioning holes, the quantity of described positioning hole equates with the quantity of air-flow path, and described flange also is provided with a plurality of supports.The closed air-flow path that forms of upper groove and lower groove, and the closure of upper groove and lower groove realizes by the welding wing plate, can guarantee like this seal of air-flow path; When using, the closed air-flow path that forms of upper groove and lower groove can be welded on the flange for the ease of fixing, and the length of wing plate just can make air-flow path be inserted into better on the flange less than the length of upper groove and lower groove, is convenient to be welded and fixed; The quantity of air-flow path is decided according to the quantity of cylinder; Positioning hole on the flange is used for the air-flow path of the upper groove of grafting and lower groove formation, then this air-flow path is welded on the flange; Support on the flange is used for fixedly thermal shield, solves the fixation problem of thermal shield, and the structure of support is relatively simple, and those skilled in the art implements also and is easy to.
Further, described upper shell is provided with the through hole that runs through upper shell, and this through hole is provided with nut.Fixing for the ease of housing offered through hole at upper shell, by adding bolt, cooperates with nut on the housing, can realize well fixing of housing.
Further, described wing plate be shaped as cuboid, its end face away from connecting head is vertical with the sideline, both sides of upper groove, lower groove.Linear the meeting at right angles of dual-side of wing plate and upper groove, lower groove, the air-flow path of being convenient to the formation of groove and lower groove is inserted in the flange better, makes welding more firm.
Further, the outlet of described each air-flow path is in the same plane.
Further, the sectional shape of described upper groove and lower groove is semicircle.
Further, connecting head is cylindrical, and its diameter is equal to or greater than 2 times of diameter of air-flow path.
Further, flange is provided with four supports, and the both sides of flange two supports that respectively distribute.
Further, also be provided with a plurality of mounting holes on the described flange.Mounting hole can be realized the fixing of flange better.
The present invention compared with prior art has the following advantages and beneficial effect:
(1) the present invention is by arranging flange, and at flange positioning hole, support, mounting hole are set, positioning hole on the flange is used for the air-flow path of the upper groove of grafting and lower groove formation, then this air-flow path is welded on the flange, support on the flange is used for fixedly thermal shield, solve the fixation problem of thermal shield, thereby so that the tightness of whole air-flow path and stability have obtained guarantee, avoided affecting the overall performance of gas exhaust manifold.
(2) the present invention arranges wing plate by the both sides in upper groove and lower groove, only wing plate need to be welded in the time of welding, can make the closed formation of groove and lower groove air-flow path, thereby guarantee the tightness of air-flow path, avoid affecting the performance of whole vent systems.
(3) linear the meeting at right angles of dual-side of wing plate of the present invention and upper groove, lower groove, the air-flow path of being convenient to the formation of groove and lower groove is inserted in the flange better, makes welding more firm.
