Embodiment
Fig. 1 a-Fig. 1 c is embodiment one the structural drawing of the throttle body of the utility model.Fig. 1 b is the sectional drawing by the section B-B among Fig. 1 a, and Fig. 1 c is the sectional drawing by the cross section C-C among Fig. 1 a.
Shown in Fig. 1 a-Fig. 1 c, be provided with air inlet sprue 13 on the throttle body body 2, rotating shaft 6 intersects vertically with air inlet sprue 13 and is installed in the body rotary shaft hole 24, and be installed with runner 4 at an end of rotating shaft 6, the position that is arranged in air inlet sprue 13 at the middle part of rotating shaft 6 is equipped with door-plate 5, position transducer 1 also is installed on body 2, and the angle position of rotating shaft 6 is measured by position transducer 1.Also be provided with throttle cable seat 8 and bypass flow channel controlling mechanism 9 on body 2, they all are arranged on the same side on the axis plane 23 of shaft axis and air inlet sprue axis formation, i.e. upside among Fig. 1 a.The throttle cable (not shown) is handled runners 4 by throttle cable seat 8, and rotating shaft 6 is rotated, and then drives door-plate 5 and rotates in air inlet sprue 13, with the valid circulation area of change air inlet sprue 13.
Shown in Fig. 1 a-Fig. 1 c, throttle cable seat 8 is from bypass flow channel controlling mechanism 9, grow along the direction parallel with rotating shaft 6, with body 2 integral die-cast moulding, and bypass flow channel controlling mechanism 9 inside include two crossing endoporus: idling air-flow upstream by-pass hole 15 and idling airflow downstream by-pass hole 16, idling air-flow upstream by-pass hole 15 forms 30 ° of angles with air inlet sprue 13, by with one voice 14 being interconnected, idling airflow downstream by-pass hole 16 and air inlet sprue 13 form with one voice 17 and be interconnected.By- pass hole 15 and 17 all forms from external process, the processing entrance of by-pass hole 16 is by a steel ball 21 shutoff, the coaxial internal structure that processes bypass flow channel controlling mechanism 9 on the elongation line of by-pass hole 15, and be equipped with idle adjusting screw 19 and spring 20, idle adjusting screw 19 can be from the airflow outlet end operation of throttle body 25, the outside idle adjusting screw 19 of regulating moves forward and backward it, thereby realizes the continuous adjusting to the circulation area of upstream by-pass hole 15 and downstream by-pass hole 16.Be provided with aperture 12 on the door-plate 5, therefore, in the door-plate closed condition, the circulation area of the adjustable bypass flow channel that the idle speed air admission circulation area mainly is comprised of upstream by-pass hole 15 and downstream by-pass hole 16, and the circulation area that door-plate aperture 12 forms forms certain slit areas that comprise that also door-plate 5 peripheries and air inlet sprue 13 form.
Along with the throttle body increase of service time, the pollutants such as carbon distribution can be constantly accumulated on each surface at air inlet runner, thereby the idle speed air admission circulation area can reduce gradually, particularly door-plate 5 peripheries can reduce fast with the slit area that air inlet sprue 13 forms, on the other hand, motor in the period of adjustment the needed air inflow of idle running also can reduce, the air inflow that just not necessarily causes with pollution reduces just in time synchronous.Therefore, normal in order to guarantee engine idling operation, may need frequently to regulate idle screw, this also is one of content of engine maintaining maintenance.Because the circulation area of bypass flow channel, and the length of side of the circulation area that forms of door-plate aperture 12 circulation area, particularly door-plate aperture 12 that form is very little with respect to its area, so the pollutant such as carbon distribution is less on the impact of its circulation area.Therefore idle speed air admission circulation area anti-pollution ability embodiment illustrated in fig. 1 is more intense.
Fig. 1 a-Fig. 1 c illustrated embodiment, by the scheme that will need to be arranged on the same side from throttle cable and the bypass flow channel controlling mechanism of peripheral operation, to be conducive to reduce the physical dimension of opposite side, thereby be conducive at real vehicle throttle body is installed, manual slow running adjustment 9 is placed outside easily arrival, the position of easy operating the property easy to adjust of idle adjusting screw 19 is significantly improved, and opposite side can not interfered with vehicle frame yet.
Charcoal canister is installed to reduce the motorcycle of motorcycle fuel evaporation thing for needs, can also a canister desorption be set at throttle body and connects mouth 3, as shown in Figure 1.
Fig. 2 is embodiment two the structural drawing of the throttle body of the utility model.
From embodiment's one different being characterised in that, in embodiment two, the idle speed air admission bypass flow channel is not to be regulated by manual idle screw, but controlled by the electric idling controlling mechanism 33 of motorized adjustment, this controlling mechanism drives idle screw rod 31 by a stepper motor 30, modulating valve 32 is moved along rectilinear direction, thereby realize the continuous adjusting to the circulation area of upstream by-pass hole 15 and downstream by-pass hole 16, this scheme is to realize regulating in real time the idle speed air admission amount by engine electronic control unit (ECU) (not shown), is conducive to the improvement of engine idle speed stability and startability.
Throttle body shown in Figure 2 is connected by circular hose interface 34 with engine inlets or air inlet tube (not shown), also can be provided with the circumferential positioning structure (not shown), and this more is conducive to reduce the size of throttle body, reduces cost.
