Description

Air cleaner for motorcycle filter core positioning device

Technical field

The utility model belongs to technical field of motorcycles, specifically, and particularly a kind of air cleaner for motorcycle filter core positioning device.

Background technique

Air-strainer is the vitals on motorcycle, for filtered air, appropriate clean air is supplied to motor.Existing air cleaner used on motorcycles adopts filer element type filtration usually, when motorcycle travels at the environment that dust is larger, likely blocks filter core on the one hand, affects the air inlet effect of motor; On the other hand, easily cause filtration unclean, make the dust in air enter Carburetor and motor, all can cause damage to Carburetor and motor.

Model utility content

Technical problem to be solved in the utility model is to provide the air cleaner for motorcycle filter core positioning device that a kind of structure is simple, smoothing effect is good.

The technical solution of the utility model is as follows: a kind of air cleaner for motorcycle filter core positioning device, comprise upper end cap (1), lower end cap (2), suction tude (3) and steam outlet pipe (4), described upper end cap (1) and lower end cap (2) phase make-up, the shell of composition air-strainer, its key is: the inside of described shell has former and later two cavitys, before shell, the antetheca of cavity upper end arranges suction tude (3), the rear cavity of shell is separated into the dilatation chamber (A) on top and the chamber of giving vent to anger (B) of bottom by filter core (9), described filter core (9) is supported by the upper end of chamber of giving vent to anger (B) all sidewalls, this filter core (9) is positioned at localization frame (11), the lower end of localization frame (11) embeds gives vent to anger in the adaptive groove of chamber (B) all sidewall upper, the diapire of described chamber of giving vent to anger (B) is low early and high after inclined-plane, the rear lower side of this chamber of giving vent to anger (B) is provided with steam outlet pipe (4), described steam outlet pipe (4) is circular arc, to the give vent to anger diapire of chamber (B) of the upper end of steam outlet pipe (4) is vertically through, the lower end of steam outlet pipe (4) is towards rear.

Adopt above technological scheme, localization frame is installed firmly, can be spacing to filter core circumference, filter core is located reliable.Air in cavity before shell through absorption, after cyclonic separation, again filtered by filter core, the air of last cleaning flows to Carburetor from chamber of giving vent to anger through steam outlet pipe, thus ensure that the air entering motor keeps clean, stop the disadvantage that Carburetor and motor damage because of unclean air, substantially prolongs the working life of motor.Meanwhile, the air before filter element filtering by absorption, cyclonic separation eliminates most of dust and particle, the air flowing through filter core is few containing dust, dust-laden granularity is little, and filter core can not be caused to block, and the patency of engine charge is secure.The diapire of chamber of giving vent to anger is low early and high after inclined-plane, and adapts with the steam outlet pipe of circular arc, can guarantee to give vent to anger smooth and easy.

Described suction tude (3) is the low serpentine flat structure in height rear end, front end, not only air output is sufficient, and to the distinguished and admirable effect having roundabout guiding, intake velocity too fast and the cylinder directly impacted in front cavity and gas cylinder when running at high speed to avoid motorcycle, effectively prevent cylinder and gas cylinder is damaged.

Described filter core (9) is rectangular flat structure, and such filter core area is large, good filtration effect, and is not easy blocking; Filter core is made up of foamed resin, and selection is convenient, and processing and fabricating is easy, and cost is low.

The upper end edge profile of described lower end cap (2) is provided with a circle groove (2a), the fin (1a) that upper end cap (1) bottom correspondence is arranged embeds in this groove (2a), and is fixed by many bolts between upper end cap (1) and lower end cap (2).The upper and lower end cap of above structure combines closely, connects not only firmly but also reliably, and good airproof performance, can not leak gas from fastening.

Beneficial effect: the utility model structure is simple, easily, filter core area is large in assembling, and filtering effect is remarkable, and not easily causes filter core to block, and has the features such as design is ingenious, cost is low, easy transformation, all applicable on various types of motorcycle.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

As shown in Figure 1 and Figure 2, the shell of air-strainer is made up of upper end cap 1 and lower end cap 2 phase make-up.The upper end edge profile of lower end cap 2 is provided with a circle groove 2a, and the fin 1a that upper end cap 1 bottom correspondence is arranged embeds in this groove 2a, and is fixed by many bolts between upper end cap 1 and lower end cap 2.The inside of air cleaner casing becomes former and later two cavitys by baffle for separating, before shell, cylinder 5 is set in cavity, and the liquid storage room 6 for storing machine oil is formed on the bottom of cavity before shell, offer pouring orifice 6a at the sidewall of liquid storage room 6 upper end, pouring orifice 6a is sealed by filling oil cover; Lowest part bottom liquid storage room 6 offers mouthful 6b that changes oil, and mouthful 6b that changes oil is by lid sealing of changing oil.

As shown in Figure 1 and Figure 2, cylinder 5 is up big and down small taper, and is fixed as one with upper end cap 1, and the lower end of cylinder 5 is positioned at the middle and lower part of cavity before shell.The antetheca of cylinder 5 upper end offers intake grill, and this intake grill is communicated with the rear end of suction tude 3, and suction tude 3 is the low serpentine flat structure in height rear end, front end, and suction tude 3 is fixed as one with the antetheca of upper end cap 1 upper end.In cylinder 5, be provided with gas cylinder 7, the upper end of this gas cylinder 7 and the roof of upper end cap 1 are fixedly linked, and the shaft axis of gas cylinder 7 and the shaft axis of cylinder 5 are positioned on straight line.Rotary flow type exhaust fan 8 is installed at top in gas cylinder 7, and the wire of rotary flow type exhaust fan 8 is drawn from the roof of upper end cap 1, and extraction place is embedded with seal ring, to prevent gas leakage.

As shown in Figure 1 and Figure 2, the rear cavity of shell is separated into the dilatation chamber A on top and the chamber B that gives vent to anger of bottom by filter core 9, and the exhaust outlet 7a that the front end on dilatation chamber A top is offered by drainage channel 10 and gas cylinder 7 upper end rear wall is communicated with.Filter core 9 is rectangular flat structure, and adopts foamed resin to make.Filter core 9 is supported by the upper end of chamber B week sidewall of giving vent to anger, and this filter core 9 is positioned at localization frame 11, and the lower end of localization frame 11 embeds gives vent to anger in the adaptive groove of chamber B week sidewall upper.The diapire of chamber B of giving vent to anger is low early and high after inclined-plane, this rear lower side of giving vent to anger chamber B is provided with steam outlet pipe 4, and steam outlet pipe 4 is circular arc, and the upper end of steam outlet pipe 4 is by vertically through for the diapire of the chamber B that gives vent to anger, and steam outlet pipe 4 and lower end cap 2 are fixed as one, the lower end of steam outlet pipe 4 is towards rear.
