Automobile air intake system

Abstract

The invention discloses an automobile air intake system. The automobile air intake system comprises a mounting end, a connecting piece, an air intake pipe and an outer cover. The air intake pipe communicates with the mounting end through the connecting piece. The air intake pipe is a polyethylene glycol terephthalate braided pipe, and nylon reinforcing ribs are further formed in the pipe wall of the air intake pipe. The outer cover is arranged on the outer portion of the air intake pipe in a sleeving manner. The polyethylene glycol terephthalate braided pipe is adopted, the braided pipe has good vibration slowing capacity, and therefore generated noise is reduced. Meanwhile, due to the fact that the braided pipe is quite flexible and poor in bearing performance, the nylon reinforcing ribs are additionally arranged in the braided pipe for reinforcement, the situation that a pipeline deforms and collapses under the influence of air intake pressure can be effectively avoided, and the system reliability is improved. The braided pipe still has the high flexibility performance even after being reinforced through the nylon reinforcing ribs, shaking happening after assembly is avoided, and reasons for generating noise are further avoided and reduced.

Description

technical field [0001] The invention relates to a vehicle air intake system. Background technique [0002] In the vehicle air intake system, due to the need to connect with the air filter and relieve the vibration caused by the engine, the air filter outlet pipe generally adopts a plastic bellows 1', such as figure 1 shown. Considering the damping ability, service life and convenience of assembly, 6 damping corrugations are designed. [0003] Due to the average damping ability of the bellows, it is more laborious to assemble with the air filter and the upper beam of the radiator; the use of plastic pipes is not effective in attenuating high-frequency intake noise, and there is a loud roar when the vehicle accelerates , The 2nd, 4th, and 6th order noises are generally high at the entire engine speed, which causes poor subjective feelings for the comfort of the passengers. Contents of the invention [0004] The purpose of the present invention is to provide an automobile ...
