Air filter device, power system with air filter device and all-terrain vehicle

Abstract

The invention discloses an air filter device, a power system with the air filter device and an all-terrain vehicle. The air filter device comprises a main air filter and an air inlet channel, wherein an air inlet is located in the air inlet channel. The air filter device is characterized in that the air inlet channel is provided with a first shell, the main air filter is provided with a second shell, the first shell and the second shell are separated, and the first shell and the second shell communicate through a pipeline; and the second shell is provided with a first filter cavity and a second filter cavity, the first filter cavity communicates with the air inlet channel, the second filter cavity communicates with the first filter cavity, the volume of the first filter cavity is larger than that of the second filter cavity, and the second filter cavity is located in the side, away from the air inlet, in the first filter cavity. According to the air filter device, the power system with the air filter device and the all-terrain vehicle, through the arrangement of the air inlet channel and the second filter cavity, multiple filtering is formed, the air filter device adapts to the severe environment while sufficient oxygen supply to a combustion chamber is guaranteed, the failure rate is reduced, the overhaul period is prolonged, and the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering, and in particular relates to an air filter device, a power system with the air filter device and an all-terrain vehicle. Background technique [0002] All-terrain vehicles are often used for field transportation, field rescue, field exploration, field construction, etc., and the field terrain is complex, such as beaches, riverbeds, forest roads, streams, and harsh desert terrains, which not only lead to large resistance to vehicle driving , and some complex and harsh terrains will seriously affect the operation of the engine, such as sand and gravel flying on the beach or desert terrain, or muddy water splashed in streams and depressions. Gas, leading to problems such as insufficient oxygen supply, lack of power, etc., which will lead to engine failure, vehicle breakdown, and even potential safety hazards. [0003] Therefore, an air filter will be installed on the engine to prevent d...

Problems solved by technology

[0002] All-terrain vehicles are often used for field transportation, field rescue, field exploration, field construction, etc., and the field terrain is complex, such as beaches, riverbeds, forest roads, streams, and harsh desert terrains, which not only lead to large resistance to vehicle driving , and some complex and harsh terrains will seriously affect the operation of the engine, such as sand and gravel flying on the beach or desert terrain, or muddy water splashed in streams and depressions. Air, resulting in insufficient oxygen supply, lack of power and other problems, it will lead to engine failure, vehicle breakdown, and even potential safety hazards

[0003] Therefore, an air filter will be installed on the engine to prevent debris from entering the engine. However, the existing air filter is only installed at the air intake of the engine and has a filter element in it. Under the harsh environment and terrain mentioned above, this kind The filter element of the air filter is very easy to be polluted and needs to be replaced frequently, which is very inconvenient, and debris is easy to accumulate in the air filter, causing the debris to enter the crankcase through the intake pipe of the crankcase and damage the engine
