A kind of air-breathing self-cleaning filter mounted on the top of the cab

Abstract

The invention discloses an overhead air-absorbing type self-cleaning filter for a cab. The overhead air-absorbing type self-cleaning filter for the cab comprises a filter body which is arranged on the top part of a car cab along the air flowing direction, and an air exhausting tube which is arranged at the air exhausting end of the filter body along the air flowing direction and communicates with a car engine or the filter body at the next grade, wherein an air feeding end of the filter body is positioned at a windward side of the top part of the car cab. The overhead air-absorbing type self-cleaning filter for the cab can overcome the defects in the prior art, such as poor environmental protection, short service lifetime and low reliability; the overhead air-absorbing type self-cleaning filter for the cab has the advantages of being high in environmental protection performance, long in service life, and high in reliability.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an air-breathing self-cleaning filter mounted on the roof of a cab. Background technique [0002] Some heavy-duty road trucks and off-highway dump trucks are located in very poor road conditions, and the air below the cab is very dirty. In addition, the exhaust pipe blows the ground dust away from the ground, and the air becomes "dirty", consisting of large particles, Composed of dust, soot, and dust. The pre-filter air inlet of the engine air filter of these cars is also arranged here, which not only increases the burden on the filter, but also shortens the maintenance cycle of the filter element in the filter, which is harmful to the early wear and tear of the engine and its power, Economics are affected. [0003] In the process of realizing the present invention, the inventors found that the prior art at least has defects such as poor environmental protection, short serv...
