Description

Technical Field

[0001] This application relates to the technical field of air filter assembly for engines, and particularly to a component for supporting an air filter. Background Art

[0002] Common existing vehicle types include trucks, buses, and special-purpose vehicles, etc., and air filters need to be installed on each type of vehicle. Since a large amount of air is inhaled during the operation of the vehicle's engine, if the air is not filtered, the dust suspended in the air is inhaled into the cylinder, which will accelerate the wear of the piston group and the cylinder. Larger particles entering between the piston and the cylinder will cause a serious "cylinder scoring" phenomenon. The air filter plays a role in filtering dust and sand grains in the air, ensuring that sufficient and clean air enters the cylinder.

[0003] According to the structural characteristics of the cab of different vehicle models to install the air filter, in some cabs with a relatively large space, the area above the engine top is relatively open, and this space can be used to arrange the air filter. For some vehicle models without restrictions on the overall vehicle length, it is also possible to arrange it on the frame at the rear end of the cab. However, for a smaller number of vehicles, in order to obtain a larger cargo box space to better meet the needs of cargo transportation and other aspects, the cab space is relatively limited, and the arrangement of the air filter will be restricted due to the compression of the engine space and the space at the rear end of the cab.

[0025] Please refer to Figure 1The present application provides a component for supporting an air filter, and the component for supporting an air filter includes: an air filter 01, a filter cover 02, a tray bracket 03, and a flywheel housing 04; the filter cover 02 is sleeved on the air filter 01, a support frame is provided at the bottom of the filter cover 02, and the support frame is connected to the tray bracket 03; the tray bracket 03 is provided on the top of the flywheel housing 04; the filter cover 02 is used to install and protect the air filter 01, the tray bracket 03 is used to support the filter cover 02, and the air filter 01 is used to filter and purify air.

[0026] First, the various components in this embodiment are introduced below:

[0027] Air filter 01: is a filter, mainly used for air filtration in engineering locomotives, automobiles, agricultural locomotives, laboratories, sterile operating rooms and various precision operating rooms. In this application, air filter 01 is used to filter air and then deliver the filtered air to the engine.

[0028] Filter cover 02: It is placed outside the air filter 01, so that the air filter 01 can be replaced at any time. A support frame is set at the bottom of the filter cover 02 so that the filter cover 02 can be fixed in the engine area. After the filter cover 02 is fixed, only the air filter 01 in the cover needs to be replaced. The filter cover 02 can be adjusted according to the size adaptability of the air filter 01 to adapt to air filters 01 of different sizes.

[0029] Tray bracket 03: a medium for fixing and supporting the air filter 01 and the filter cover 02. The tray bracket 03 is arranged on the top of the flywheel housing 04. The filter cover 02 is connected to the flywheel housing 04 through the tray bracket 03. In order to further maintain stability, triangular stabilizing structures are added on both sides of the bottom of the tray bracket 03.

[0030] Flywheel housing 04: A protective shell mounted outside the flywheel, which has an uneven structure and is not suitable for directly placing the air filter 01 on the flywheel housing 04. Therefore, the present application adds a tray bracket 03 with a flat tabletop structure as a connecting structure between the air filter 01 and the flywheel housing 04.

[0031] In this embodiment, the air filter 01 is directly mounted on the flywheel housing 04 through the filter cover 02 and the tray bracket 03, so that the air filter 01 is installed on the engine. It has a firm support, simple layout, reasonable structure, strong versatility, and occupies a small proportion of the engine area space. At the same time, it solves the problem that the cab space is small and the air filter 01 cannot be placed, thereby improving the adaptability of the engine.

[0032] In an optional embodiment, the support frame is a "匸"-shaped structure, and a hole is opened in the support frame.

[0033] In an optional embodiment, a threaded hole is opened on the tray bracket 03, and the threaded hole corresponds to the hole position of the support frame, so that a bolt or a screw passes through the hole of the support frame and the threaded hole to connect the support frame with the tray bracket 03.

[0034] In the above two optional embodiments, in order to stably connect the filter cover 02 to the tray bracket 03, screws or bolts can be used for connection. The screws or bolts pass through the holes of the support frame and are screwed into the threaded holes on the tray bracket 03. After tightening the screws or bolts, the "匸"-shaped support frame plane can fit tightly with the flat surface of the tray bracket 03, so that the filter cover 02 is fixedly set on the flywheel housing 04.

[0035] In an optional embodiment, the support frame is a columnar structure with external threads at the bottom end, and the tray bracket 03 is provided with a hole with internal threads corresponding to the position of the support frame, and the support frame is connected to the tray bracket 03 via external threads and internal threads.

[0036] In this optional embodiment, in addition to setting the support frame to a "匸"-shaped structure, the support frame can also be set to a columnar structure, and an external thread is added to the bottom of the columnar structure, and the external thread can be matched with the internal thread of the hole on the tray bracket 03. After the support frame of the filter cover 02 is screwed into the tray bracket 03 and the angle and position are adjusted, the air filter 01 is installed in the filter cover 02, which can also achieve the purpose of fixing the air filter 01 on the flywheel housing 04.

[0037] In an optional embodiment, the tray bracket 03 is a deformed structure in the shape of a Chinese character “匸”.

[0038] In an optional embodiment, the tray bracket 03 is provided with a horizontal extension end at one end and a vertical extension end at the other end, so that the tray bracket 03 is fixedly connected to the flywheel housing 04 in accordance with the shape of the flywheel housing 04 .

[0039] In the above two optional embodiments, the outer shape of the flywheel housing 04 is an unconventional shape. According to the shape of the flywheel housing 04, a small plane and a vertical groove with a certain depth are selected. The tray bracket 03 is then designed according to the position and size of the small plane and the vertical groove, that is, on the basis of the "匸" shape of the tray bracket 03, a horizontal extension end and a vertical extension end are added. The horizontal extension end is connected to the selected small plane on the flywheel housing 04 by screws or bolts; the vertical extension end is inserted into the selected vertical groove on the flywheel housing 04, and then secured by screws or bolts. In summary, a stable connection between the tray bracket 03 and the flywheel disc is achieved.

[0040] In an alternative embodiment, the air filter 01 is a cylindrical filter. One end of the air filter 01 is an air inlet, and the other end is an air outlet, which is communicated with the air inlet of the engine.

[0041] In this alternative embodiment, the air filter 01 can adopt a common cylindrical filter. The dirty air enters from the air inlet of the air filter 01. After being filtered and purified by the air filter 01, it is discharged from the air outlet of the air filter 01 and enters the air inlet of the engine through a transmission pipeline, thereby ensuring that the air in the engine is filtered air, reducing the wear of engine parts, lowering the maintenance cost, and making the diesel combustion in the engine more sufficient, improving the engine power.

[0042] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will be accorded the widest scope consistent with the principles and novel features disclosed herein.
