Abstract
The utility model relates to a motorcycle secondary air supplement device which is characterized in that the device comprises a secondary air valve and an air filter for matching with the secondary air valve. The installation base of the secondary air valve is arranged on the air filter. A vent hole which is communicated with a filter core is arranged in the installation base. The vent hole is communicated with the air inlet of the secondary air valve. A sealing element is arranged between the air filter and the secondary air valve. The connecting base of the secondary air valve is integrated with the installation base of the outer casing of the filter. Therefore, relative pipes and connecting parts can be reduced. The motorcycle secondary air supplement device has the advantages of more convenient installation, simple structure and beautiful appearance. The air outlet port of the secondary valve is connected with the vent pipe, and the other end of the vent pipe is connected with the metal intake pipe on the engine or the exhaust pipe or a unidirectional leaf valve. Therefore, secondary air can enter the air exhaust port of the engine or the exhaust pipe from the pipe, waste gas which is not completely combusted, contains harmful components and is discharged from the engine goes on combusting to improve the exhaust emission.
Description
Technical field
The utility model relates to a kind of secondary air supplementing device for motorcycle.
Background technique
In order to reduce the pollution of motorcycle engine exhaust emissions, the motorcycle that has is provided with secondary air supplementing device.Existing secondary air supplementing device generally has dual mode, and a kind of mode is with mounting bracket secondary air supplementing device to be fixed on motor to place outward, and its pipeline structure complexity influences outward appearance, and inconvenience, cost of production height are installed; Also having a kind of is secondary air supplementing device to be directly installed on engine cylinder cover, because the temperature of motor is than higher, the rubber parts of suction valve is aging easily, and it can only be assemblied on the cylinder cap, be inconvenient to be installed in engine cylinder head, on cylinder body and the outlet pipe, application area is restricted.
The model utility content
The utility model overcomes the deficiencies in the prior art and provides a kind of and can conveniently install, and is simple in structure, can reduce a kind of secondary air supplementing device for motorcycle of exhaust emissions amount.
In order to achieve the above object, the utility model is to realize like this, it provides a kind of secondary air supplementing device for motorcycle, it is characterized in that: comprise secondary air valve and the air-strainer that cooperates with secondary air valve, on air-strainer, be provided with the fitting seat of secondary air valve, be provided with the vent that communicates with filter core in the fitting seat, this vent communicates with the suction port of secondary air valve; Between described air-strainer and described secondary air valve, Sealing is housed.
Described secondary air valve comprises valve body, suction port is established thereon, be provided with the air outlet thereon, the suction port place is provided with the connecting base that is connected with described air-strainer fitting seat, be convenient to described secondary air valve is installed on the described air-strainer, the air outlet of described secondary air valve is connected with breathing pipe.
Described secondary air valve also comprises the valve block that ends that air inlet can be opened or end, one end and the drive mandrel of fixing by valve block, be set in the spring on the drive mandrel, the diaphragm that is connected with the drive mandrel the other end, be installed in the negative pressure lid on the valve body, the negative pressure lid is fixed on diaphragm on the valve body, is provided with the axle bed that described drive mandrel is installed in described valve body, so that make directed the moving of drive mandrel energy, the negative pressure lid is connected with the negative pressure pipe.
The utility model advantage compared with prior art is, because the fitting seat of secondary air inlet valve connecting base and empty filter shell is connected as a single entity, can reduce associated pipe and link, install more convenient, simple in structure, appearance looks elegant, because the air outlet of described secondary air valve is connected with breathing pipe, the breathing pipe the other end is connected with air inlet metal tube or one-way leaf valve on motor or the outlet pipe, make secondary air to enter in engine exhaust port or the outlet pipe by this pipeline, the imperfect combustion waste gas that contains harmful ingredients that motor is discharged burns away, and reaches the purpose of improving discharging.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, it is a kind of secondary air supplementing device for motorcycle, comprise secondary air valve and the air-strainer that cooperates with secondary air valve, on air-strainer, be provided with the fitting seat 11 of secondary air valve, be provided with the vent 12 that communicates with filter core in the fitting seat, this vent communicates with the suction port 101 of secondary air valve, Sealing 2 is housed between air-strainer and secondary air valve, on secondary air valve, be provided with the connecting base 102 that cooperates with fitting seat, secondary air valve can be installed on the air cleaner casing 1, the other end of the vent on the fitting seat leads to the suction port of secondary air valve, can enter secondary air valve easily by the air behind the filter element filtering like this.
In the present embodiment, secondary air valve comprises the valve body 10 that can be installed on the sky filter shell 1, and connecting base 102 is located on the valve body, is provided with the suction port 101 and the air outlet 103 that can interconnect on valve body, and the air outlet is communicated with breathing pipe 13; Secondary air valve also comprise air inlet can be opened or closed by valve block 3, one end and the drive mandrel 5 of fixing by valve block, be set in the spring 4 on the drive mandrel, be connected the diaphragm 6 of drive mandrel 5 the other ends, negative pressure pipe 8 with diaphragm is fixed on the negative pressure lid 7 on the suction valve fitting seat 10 and is communicated with the negative pressure lid is provided with seal ring 9 between negative pressure lid and valve body; In valve body, be provided with the axle bed 104 that drive mandrel is installed, so that make directed the moving of drive mandrel energy.
During use, under the elastic force effect of spring 4, leave suction port 101 end faces by valve block 3, this moment, suction port was opened, and can flow to from suction port from the gas in the empty filter shell 1, and 103 flow to breathing pipe 13 from the air outlet; When negative pressure increased to certain value, the suction-combining force of diaphragm 6 was greater than the elastic force of spring 4, and diaphragm 6 pulling drive mandrel 5 open and close valve block with inlet close at this moment.
Because secondary air inlet valve housing and empty filter shell are connected as a single entity, can reduce associated pipe and link, install more convenient, simple in structure, appearance looks elegant, because the air outlet of described secondary air valve is connected with breathing pipe 13, the breathing pipe the other end is connected with air inlet metal tube or one-way leaf valve on motor or the outlet pipe, make secondary air to enter in engine exhaust port or the outlet pipe by this pipeline, the imperfect combustion waste gas that contains harmful ingredients that motor is discharged burns away, and reaches the purpose of improving discharging.
