Description
Technical field
The utility model relates to automobile technical field, specifically is convenient to the gas exhaust manifold shell construction of welding.
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, after the manifold dsah-pot, air flow channel starts difference, and the quantity of corresponding engine cylinder, as four cylinder engine Jiu You tetra-roads, corresponding five roads of five cylinder engines, import air respectively in each cylinder.With NA Naturally Aspirated Engine, due to after intake manifold is positioned at closure, so, when engine throttle aperture hour, in cylinder, can't be drawn onto enough air, will cause the mainfold vacuum degree high; And, when the engine throttle aperture is large, the degree of vacuum in intake manifold will diminish.Therefore, spray the fuel feeding engine and all can on intake manifold, install a pressure meter, supply with ECU and judge the engine load, and give appropriate oil spout.And gas exhaust manifold is connected with engine cylinder, the exhaust of each cylinder is put together and imports exhaust manifold, pipeline structure that band is disagreed.To it requirement mainly, reduce exhaust resistance as far as possible, and avoid phase mutual interference between each cylinder.During the exhaust undue concentration, between each cylinder, can produce the phase mutual interference, during namely certain cylinder exhaust, just in time meet other cylinder and alter the next waste gas that there is no 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, or branch of two cylinders, and each branch is lengthened as far as possible and moulding-with the gas reduced in different pipes, influence each other.In order to reduce exhaust resistance, some racing car adopts Stainless Steel Tube to manufacture gas exhaust manifold.
At present, there is the solid problem of not prison welding in general gas exhaust manifold, and especially the joint of each branch's mouth of pipe and flange, be easy to occur that not prison welding is solid, causes gas leakage, affects the performance of whole vent systems.
The model utility content
The utility model provides the gas exhaust manifold shell construction of being convenient to welding, has solved each branch's mouth of pipe of gas exhaust manifold and the joint of flange in the past, is easy to occur that not prison welding consolidates, and causes gas leakage, affects the problem of whole vent systems performance.
The utility model is that the technical solution problem is achieved through the following technical solutions: the gas exhaust manifold shell construction of being convenient to welding, 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 forms a connecting head cylindraceous, the quantity of described upper groove equates with the quantity of lower groove, the corresponding lower groove of groove on each, and a upper groove and a lower groove form 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 groove and lower groove.Upper groove and lower groove are closed forms air-flow path, 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 formed of upper groove and lower groove, for the ease of fixing, can be welded on flange, and the length that the length of wing plate is less than groove and lower groove just can make air-flow path be inserted into better on flange, is convenient to be welded and fixed; The quantity of air-flow path is determined according to the quantity of cylinder.
Further, described upper shell is provided with the through hole that runs through upper shell, and this through hole is provided with nut.For the ease of fixing of housing, offer through hole on upper shell, by additional bolt, with the nut on housing, coordinate, can realize well the 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 groove and lower groove formation is inserted in flange better, convenient welding.
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, described connecting head is cylindrical, and its diameter is equal to or greater than 2 times of diameter of air-flow path.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model arranges wing plate by the both sides in upper groove and lower groove, in the time of welding, only wing plate need to be welded, 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.
(2) linear the meeting at right angles of dual-side of wing plate of the present utility model and upper groove, lower groove, the air-flow path of being convenient to groove and lower groove formation is inserted in flange better, makes welding more firm.
