Abstract

An air cleaner is composed of an air cleaner cover, an air cleaner outer shell and a filter screen unit, wherein the air cleaner outer shell is combined with the air cleaner cover to form an air intake passage. The filter screen unit is clamped between the air cleaner cover and air cleaner outer shell so that the internal space of the locomotive can be fully applied, thereby expanding the dimension of the air cleaner, canceling the inlet pipe that is protruding outwards from the conventional air cleaner and then changing into an inbuilt air intake passage. The air intake passage is formed by the air cleaner cover and air cleaner outer shell. Moreover, the structure of air cleaner is changed into a single air inlet port and the main line position of the locomotive is allocated once again. The utility model has the advantages: maximize the volume of the air cleaner and at the same time avoid the issues that too short air intake passage results in the noise increasing.

Description

Air-strainer

Technical field

The utility model relates to a kind of air-strainer of maximization, utilizes air filter cover and air cleaner casing to form its gas-entered passageway.

Background technique

Locomotive engine need suck a large amount of air in the running and produce power with burns gasoline, yet, damage engine cylinder for avoiding meetings such as airborne sand grains dust, so air can be filtered with air-strainer earlier before entering cylinder.

See also Fig. 1, Fig. 1 is the schematic representation of a locomotive.The main car frame 11 of locomotive 10 is extended towards the rear lower side by head pipe 15, has hung many spare parts such as air-strainer 17, engine 19 on main car frame 11, and wherein, air-strainer 17 is positioned at the top of engine 19, is used to filter the air that enters engine cylinder.

Please consult Fig. 2 A and Fig. 2 B simultaneously, Fig. 2 A is the top view that places air-strainer on the main car frame, Fig. 2 B is along the A-A hatching of Fig. 2 A and the sectional view of sectility, air-strainer 17 has a pair of outstanding left and right suction tude 14, be respectively in the both sides of main car frame 11, ambient air can enter air-strainer 17 by left and right suction tude 14 simultaneously, introduces engine 19 again after filter screen 16 filters.

The main line of locomotive (comprising power line, throttle line, brake line etc.) 12 and then main car frame 11 extends through between two suction tude 14.

Shown in Fig. 2 A, between air-strainer 17 and main car frame 11, there is a space C who is not used (indicating) with dotted line.Under the trend that at present air-strainer maximizes, the utility model promptly utilizes this space C and the size of air-strainer is increased, and the configuration of the structure of air-strainer and main line also cooperates modification in addition.

The model utility content

A purpose of the present utility model is to provide an air-strainer, and it can make full use of the locomotive inner space and the size of air-strainer is increased, and cancels the outwards outstanding suction tude of known air-strainer, and makes built-in gas-entered passageway into.

Another purpose of the present utility model is to utilize air filter cover and air cleaner casing to form this gas-entered passageway.

Another purpose of the present utility model is that the structure of revising air-strainer makes single suction port into, and the position of the main line of configuration machine car again.

The purpose of this utility model is achieved in that air-strainer comprises an air filter cover, an air cleaner casing and a filter screen group.Wherein air cleaner casing and air filter cover combination and form a gas-entered passageway.The filter screen group is interposed between air filter cover and the air cleaner casing.Air-strainer has single suction port, and the main line of locomotive and suction port are respectively in the both sides of main car frame.The utility model has the advantages that, make the volume maximization of air-strainer, in addition, avoided gas-entered passageway too short-range missile cause problems such as noise increase.

Embodiment

See also Fig. 3 A and Fig. 3 B, Fig. 3 A and Fig. 3 B figure are the three-dimensional exploded views of the utility model air-strainer of being observed by opposite direction respectively.Air-strainer of the present utility model comprises an air filter cover 371, a filter screen group 373 and an air cleaner casing 375.Wherein, filter screen group 373 is interposed between air filter cover 371 and the air cleaner casing 375.Filter screen group 373 comprises a framework 378 and a filter screen (being shown among Fig. 4) 379, and filter screen 379 is installed in the framework 378.One suction port 377 is set on air cleaner casing 375, is used for ambient air is introduced air-strainer.

Please consult Fig. 4 simultaneously, air filter cover 371 and air cleaner casing 375 combinations and form a gas-entered passageway, this gas-entered passageway is from the suction port 377 tortuous filter screens 379 that extend to the filter screen group, and the arrow of Fig. 3 A, Fig. 3 B and Fig. 4 shows the direction that air flows along gas-entered passageway.

What must emphasize is that in the present embodiment, air-strainer only has single suction port 377.See also Fig. 5, when air-strainer was installed in main car frame 51, suction port 377 and locomotive main line (comprising power line, throttle line, brake line etc.) were listed in the both sides of main car frame 51 in 52 minutes.

Comparison diagram 2A and Fig. 5 are as can be known, the utility model increases the size of air-strainer, known techniques originally not usage space C to have changed the volume that is increased by air-strainer at the utility model occupied, and the outwards outstanding originally suction tude 14 of known techniques, in the utility model, make built-in gas-entered passageway into, and this gas-entered passageway is to utilize air filter cover 371 and air cleaner casing 375 to form, and so can make the volume maximization (maximizing) of air-strainer.In addition, for avoid gas-entered passageway too short-range missile cause problems such as noise increase, the utility model is designed to tortuous extension with gas-entered passageway, still has certain-length to guarantee it in limited space.
