Abstract
A throttle mainly solves problems that the existing throttles on motorcycle motors can not realize uniform air intakes of cylinders and are large in space occupation. The throttle is characterized in that one end of an air inlet (5) is communicated with a passage (4) of a casing (1) while the other end is communicated with an air inlet branch (8), and the air inlet branch (8) is connected with a stepping motor (11) via a tee (9) and an air inlet pipe (10). The casing and the stepping motor are separated by the throttle, and air can be uniformly distributed into different cylinders by aid of the tee and bypass pipes, so that the throttle has the advantages of keeping air intake of each cylinder uniform and only occupying small space.
Description
Technical field:
The utility model relates to a kind of air inlet system of motorcycle engine, belongs to a kind of throttle body.
Background technique:
At present, closure on the twin-tub motorcycle engine mainly is made up of housing, throttle blade, throttle plate pin and oil sprayer etc., on housing, be provided with 2 passages, throttle blade and throttle plate pin are installed in described passage, described oil sprayer is installed on the outer side wall of housing, on housing, also be provided with stepper motor and position transducer, position transducer can detect the unlatching size of throttle blade, feedback signal realizes idle speed control by the air by-pass amount in the step motor control throttle valve bypass pipeline then.There is following defective in above-mentioned closure: 1, air enters from an end, makes that the air inflow of each cylinder is inhomogeneous, causes the output power of motor to reduce, and causes the vibration of motor, strengthens the noise of motor, and then has shortened the working life of motor; 2, stepper motor and closure housing are integral structure, and it is big to take up room, and are not easy to the complete vehicle structure design.
The model utility content:
In order to overcome the inhomogeneous and big deficiency that takes up room of air inflow that closure on the existing motorcycle engine makes each cylinder, the utility model provides a kind of throttle body, this throttle body separates housing and stepper motor, by threeway and bypass tube air inlet is evenly distributed to each cylinder, has the even and little characteristics that take up room of air inflow of each cylinder.
The technical solution of the utility model is: this throttle body comprises housing, throttle blade and throttle plate pin, on housing, be provided with 2 passages, throttle blade and throttle plate pin are installed in described passage, on housing, also be provided with idling compensation suction port and position transducer, one end of suction port communicates with the passage of housing, the described suction port the other end communicates with air intake branch, and described air intake branch links to each other with stepper motor by threeway and suction tude.
Described stepper motor fixes by scaffold and housing.
Described threeway is positioned at the middle part of air intake branch.
The utlity model has following beneficial effect: owing to take such scheme, air enters suction port respectively by air intake branch after entering from suction tude again, make that the air inflow of each cylinder is even, the idling complemental air of each cylinder is even, the stable output power of motor, reduce vibration, eliminated noise, improved the working life of motor.The housing of stepper motor and closure is a split-type structural, and the housing of closure takes up room little, and stepper motor can be installed according to complete vehicle structure and go up in place, is convenient to the structural design of car load.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
1-housing among the figure, 2-throttle blade, 3-throttle plate pin, 4-passage, 5-suction port, 6-position transducer, 7-linkage structure, 8-air intake branch, 9-threeway, 10-suction tude, 11-stepper motor, 12-scaffold.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, this throttle body comprises housing 1, throttle blade 2 and throttle plate pin 3, is provided with 2 passages 4 on housing 1, and housing 1 is made up of two monomers that are connected by linkage structure 7.Throttle blade 2 and throttle plate pin 3 are installed in described passage 4, on housing 1, also be provided with idling compensation suction port 5 and position transducer 6, suction port 5 one ends communicate with the passage 4 of housing 1, the other end of described suction port 5 communicates with air intake branch 8, and described air intake branch 8 links to each other with stepper motor 11 by threeway 9 and suction tude 10.In use, air enters suction port 5 respectively by air intake branch 8 again after suction tude 10 enters, and makes that the air inflow of each cylinder is even, the idling complemental air of each cylinder is even, and the stable output power of motor has reduced vibration, eliminate noise, improved the working life of motor.Stepper motor 11 is a split-type structural with the housing 1 of closure, and the housing 1 of closure takes up room little, and stepper motor 11 can be installed according to complete vehicle structure and go up in place, is convenient to the structural design of car load.
Described stepper motor 11 fixes by scaffold 12 and housing 1.Stepper motor 11 also can be installed to other position according to the structural design of car load, and is flexible.
Described threeway 9 is positioned at the middle part of air intake branch 8.Make the air inlet in the suction tude 10 in air intake branch 8, distribute more even.
Claims (3)
