Description

Air inlet manifold branch

Technical Field

The utility model relates to an automobile parts field, concretely relates to air intake manifold.

Background

The intake manifold refers to an intake line from behind a carburetor or throttle body to before an intake port of a cylinder head. Its function is to distribute the mixture of air and fuel oil from carburetor or throttle body to the intake channel of each cylinder. The design of the intake manifold is also highly questionable, and in order to make the combustion conditions the same for each cylinder of the engine, the manifold length and the bending degree of each cylinder should be as identical as possible. Since the engine is operated in four strokes, each cylinder of the engine is pulsed, with the longer manifold being empirically suited for low speed operation and the shorter manifold for high speed operation. Today's intake manifolds have changed from the original aluminum material to a plastic material. The main advantages of plastic intake manifolds are lower cost and lower weight.

However, in the process of automobile moving, the automobile shakes more violently, and the intake manifold is generally fixedly connected with the cylinder only by the flange; severe shaking of the automobile may cause deformation of the flange, thereby reducing the air tightness of the connection between the cylinder and the intake manifold; in addition, the flutter may also cause deformation of the intake manifold, which may affect its performance.

Therefore, it is an urgent need for those skilled in the art to improve the existing intake manifold to overcome the above problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a sound construction, non-deformable, and maintain convenient air intake manifold.

In order to achieve the above purpose, the utility model adopts the technical scheme that: an intake manifold comprises an intake manifold and a plurality of intake branch pipes, wherein the intake branch pipes are connected with cylinders through flanges; the method is characterized in that: the intake manifold further comprises a reinforcing cross beam, and the reinforcing cross beam is suitable for being fixedly arranged in the automobile body; a plurality of mounting feet extending upwards are fixedly arranged on the outer side of the flange, and the mounting feet are fixedly connected with the reinforcing cross beam through fasteners; and a plurality of cushion pads are fixedly arranged on the reinforcing beam, extend downwards and are clamped between the adjacent air inlet branch pipes.

As an improvement, a connecting cavity is arranged between the air inlet main pipe and the air inlet branch pipe, and the air inlet main pipe, the air inlet branch pipe and the connecting cavity are all made of plastics; the connecting cavity comprises an upper shell and a lower shell, the upper shell and the lower shell cover the air inlet main pipe and the air inlet branch pipes and are fixedly and hermetically connected through hot melting. The structure is convenient to process, low in cost, independent in structure and convenient to maintain.

The improved structure is characterized in that an observation cleaning hole is formed in the connecting cavity, and a plug is detachably arranged at the observation cleaning hole. When the plug is opened, the dust deposition condition in the air inlet manifold can be observed by observing the cleaning hole, and the dust suction pipe can be stretched into the observing and cleaning hole for cleaning.

Compared with the prior art, the utility model has the advantages of: the flange is connected on the reinforcing beam through the mounting foot, can show the possibility that reduces the flange and warp. In addition, the arrangement of the cushion pad can play a role in damping and buffering, reduce the vibration of the air inlet branch pipe, prevent the air inlet branch pipe from deforming and ensure the normal use of the air inlet manifold.
