Abstract
The utility model relates to an intake manifold, in particular to an intake manifold which is integrally produced and cast by plastics, which mainly aims at the problem that the intake manifold cast by metal materials in the prior art is large in mass, complicated in processing and the like, and provides the intake manifold which is integrally produced and cast by plastics, wherein the intake manifold is simple and reasonable in structure, light in weight and low in cost. The main technical scheme of the utility model comprises that the intake manifold mounted between an engine lever head and a gas-saving door body is formed by a resonant cavity and a gas inlet branched pipe, a reinforcing rib A is disposed between the resonant cavity and the gas inlet branched pipe, and the resonant cavity is equipped with a reinforcing rib B and a reinforcing rib C. The whole of the intake manifold is integrally cast by plastics, thereby reducing the total weight of the intake manifold. The strength of the plastics is lower than that of the metal materials, on the premise that thickness is not increased, reinforcing ribs needs to be strengthened by strength, and the reinforcing ribs can solve strength problems after the materials are lessened.
Description
Technical field
The utility model relates to a kind of intake manifold, refers in particular to a kind of intake manifold that adopts the integrated manufacturing casting of plastics.
Background technique
Intake manifold can rationally arrive each firing chamber with air distribution uniformly in order to connect engine cylinder head and throttle body.
As a kind of publication number is a kind of air intake manifold of automotive engine of CN2869354, comprises that four air inlets are in charge of and a resonant cavity, and the symmetric relation that has between any two is in charge of in four air inlets.The cross section that air inlet is in charge of is a level and smooth closed hoop curve, and is mutually the same at the equivalent diameter that a projection plane has identical projection place.Same projection place that four air inlets are in charge of on a plane has identical equivalent diameter; And along air-flow direction, one section that begins from resonant cavity in degree, its equivalent diameter is in charge of the increase of center line extended distance with air inlet and is increased smoothly, until a stationary value, the equivalent diameter that described then four air inlets are in charge of remains on described stationary value, contacts until cylinder head; And its length difference each other is not more than each air inlet and is in charge of 4% of center line Mean length.
The weight of automobile directly causes the height of oil consumption, motor and accessory thereof are the critical pieces of automobile, alleviate its weight and play the effect that gets instant result reducing oil consumption, and the weight on car body shell, chassis can not alleviate too much, otherwise the Safety performance for automobile can exert an influence, so the reduction of motor and component weight thereof has very important significance for alleviating vehicle weight.
Summary of the invention
The utility model mainly is problems such as the intake manifold quality of casting at the existing in prior technology metallic material is big, processed complex, provides a kind of simple and reasonable for structure, and is in light weight, the intake manifold of the integrated manufacturing casting of the employing plastics that cost is low.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: intake manifold is installed between engine cylinder head and the throttle body, it is in charge of by resonant cavity and air inlet and forms, be provided with stiffening rib A between resonant cavity and air inlet are in charge of, resonant cavity is provided with stiffening rib B and stiffening rib C.Intake manifold integral body adopts the plastics integrally casting, has alleviated the gross weight of intake manifold.Plastics decrease than the intensity of metallic material, under the prerequisite that does not increase thickness, need stiffening rib to strengthen firm degree.Stiffening rib can remedy the strength problem of material after tailing off.
Each air inlet be in charge of and resonant cavity between be provided with stiffening rib A.Stiffening rib A is evenly distributed between each air inlet is in charge of, and makes the intake manifold each several part stressed more even.
Described stiffening rib A quantity is four.Four stiffening rib A have disperseed support force, can make structure more firm, stable.
Described stiffening rib B is arranged on the resonator outmost turns and connects air inlet and is in charge of.Stiffening rib B plays the effect of reinforcement, rock-steady structure to the intake manifold outer ring.
Described stiffening rib C quantity is some, and orthogonal arranged in a crossed manner in resonator surface.Adopt stiffening rib C, can significantly reduce the quantity of material of resonant cavity, and remedy the strength problem of material after tailing off.
The suction port of described resonator is provided with groove A, and the suction port that air inlet is in charge of is provided with groove B; Former aluminum alloy intake manifold exists at jointing leaks, and the suction port of resonator is provided with groove A now, and the suction port that air inlet is in charge of is provided with groove B, can effectively prevent to leak after groove A, groove B use rubber seal.
Measuring rod A, measuring rod B, measuring rod C have been wholely set on the described resonator; This measuring rod A, measuring rod B, measuring rod C are aluminums, and are to assemble up with metal tube on aluminum alloy air inlet manifold, and the way that the utility model adopts directly casting to come out can reduce number of components and installation step, reduces cost.
Be wholely set suction pressure temperature transducer A on the described resonator, described air inlet is in charge of and is wholely set suction pressure temperature transducer B; Because the existence of two electric injection systems is arranged, therefore former aluminum alloy intake manifold is installed into atmospheric pressure temperature transducer place and has two states, needs two moulds, now adopts cast inblock, as long as can disposable casting with unified mould.
The utility model has following advantage:
1. former intake manifold material is an aluminum alloy, use plastics symbols composite material instead after, weight reduction helps the motor lightweight.
2. the plastic air intake manifold inner chamber is more smooth than aluminum alloy air inlet manifold, can effectively reduce intake resistance, improves power.
