Description

Locomotive

Technical field

The utility model relates to a kind of locomotive, especially can prevent the locomotive in the rainwater intrusion air inlet pipe.

Background technology

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 airfilter earlier before entering cylinder.

See also Fig. 1, Fig. 1 is the scheme drawing of a locomotive.The vehicle frame of locomotive 10 is responsible on 11 and has been hung many spare parts such as airfilter 17, engine 19, and wherein, airfilter 17 is positioned at the top of engine 19, is used to filter the air that enters engine cylinder.

Please consult Fig. 2 and Fig. 3 simultaneously, Fig. 2 is the back view that places airfilter on the main car frame, Fig. 3 is along the A-A hatching of Fig. 2 and the cutaway view of sectility, airfilter 17 utilizes a pair of connecting part 12 to be locked on vehicle frame and is responsible on 11, and airfilter 17 has a pair of outstanding left and right air inlet pipe 14, be respectively in vehicle frame and be responsible for 11 both sides, outside air can enter airfilter 17 by left and right air inlet pipe 14 simultaneously, introduces engine 19 again behind the sand grains dust in filter screen 16 filtered airs.

Air inlet pipe 14 is provided with at the periphery of its opening and holds up wall 141,142,143, locomotive is when advancing, rainwater can enter air inlet pipe 14 and vehicle frame from the space on the locomotive shell and be responsible between 11, hold up wall 143 former the design and will stop rainwater, yet, cause rainwater still may walk around and hold up wall 143 and be inhaled in the air inlet pipe 14 along with air because size is too little.

The utility model content

The purpose of this utility model is to provide a kind of locomotive, and its airfilter can effectively prevent the rainwater intrusion.

The purpose of this utility model is achieved in that a kind of locomotive, comprises the vehicle frame person in charge and an airfilter.Airfilter comprises an admission port and an extension, and extension is arranged on the admission port side and is fixed in vehicle frame and is responsible for.

Above-mentioned extension can stop effectively that rainwater enters in the airfilter, simultaneously can be as the usefulness of closing component structure.

Advantage of the present utility model is that airfilter can effectively prevent in the rainwater intrusion air inlet pipe.

The specific embodiment

Below especially exemplified by preferred embodiment and cooperate appended graphic elaborating.

Please consult Fig. 4, Fig. 5 and Fig. 6 simultaneously, the airfilter 27 of locomotive of the present utility model comprises a protecgulum 28, a housing 29 and a filter screen 26.Wherein, filter screen 26 is arranged in the cavity that is combined into by protecgulum 28 and housing 29, is used to filter the air that enters airfilter 27.

Admission port 24 is arranged on the housing 29, is used for outside air is introduced airfilter 27.Housing 29 has an extension 22, and this extension 22 extends along the fore-and-aft direction of locomotive, is used for that airfilter 27 is locked in vehicle frame and is responsible for 11 (diagram is not arranged).In addition, it is other that this extension 22 is arranged on admission port 24, has enough sizes, can effectively stop rainwater, prevents that rainwater is along with air is inhaled in the airfilter 27.

Protecgulum 28 has the wall of holding up 241,242, when 29 combinations of protecgulum 28 and housing, holds up wall 241,242 perpendicular to extension 22, and holding up wall 241,242, to be positioned at admission port 24 just other, is used to stop rainwater.In addition, hold up wall 241,242 and connect airtight in extension 22 when combination, the slit enters admission port 24 between wall 241,242 and the extension 22 from holding up to avoid rainwater.

Conclude above narration as can be known, the utility model is used for effectively stopping that at the admission port 24 other extensions 22 that size increase is set rainwater enters airfilter 27.Because size increases, and mechanical strength is enough, can therefore make extension 22 extend in addition, be responsible on 11 so that airfilter 27 can be locked in vehicle frame by extension 22 simultaneously as the usefulness of closing component structure along the fore-and-aft direction of locomotive.
