Abstract

The invention relates to an air intake service pipe assembly including a rain cover, an air intake service pipe, and a corrugated pipe. The top of the rain cover is long semicircle surface, rain flowsdown along the smooth surface, a grille-shaped stop board is arranged on the lower part of the rain cover, the section of the air intake service pipe is ellipse, bosses A are arranged on two sides ofthe upper part of the rain cover and inserted into the rain cover, and the upper part of the air intake service pipe is connected with the corrugated pipe. The air intake service pipe assembly is simple in structure, the airflow resistance is small, the rain and leaves and the like are not absorbed into the air intake service pipe, the cost is low, and the whole vehicle benefit can be improved.

Description

technical field [0001] The invention relates to a commercial vehicle engine intake system, in particular to an intake intake pipe assembly. Background technique [0002] The air inlet of the existing product is on the side, and the water retaining structure is complex. A large mold needs to be invested and the cost is high. Contents of the invention [0003] In order to solve the above problems, the present invention provides an intake air inlet pipe assembly with simple structure and low manufacturing cost. [0004] The technical solution adopted in the present invention is: an air inlet pipe assembly, including a rain cover, an air inlet pipe and a bellows, characterized in that: the top of the rain cover is a long semicircular curved surface, and the rainwater along the The smooth curved surface flows down, and the lower part is equipped with a grille-shaped baffle; the cross-section of the air inlet pipe is oval, and there are bosses A on both sides of the upper part...
