Description
Technical field:
The present invention relates to motorcycle electric spraying throttle-valve body structure.
Background technique:
Motorcycle two-chamber throttle-valve body structure is made up of throttle blade, throttle plate pin, twist mechanism in two front and back of integrated type cavity, the cavity at present; Two cavity geometry air-flow intake ducts are cylindrical cavity, the air-flow air outlet channel is a diffusing opening conical cavity outwardly, respectively there is level to be enclosed within movingly in the axle sleeve hole for throttle plate pin on the cavity of front and back to front shaft sleeve, rear axle housing, preceding cavity rear axle housing and rear chamber front shaft sleeve disjunctor, cavity is located by connecting before and after realizing; Throttle blade is the oval plate-like of cutting sth. askew, after a throttle plate pin passes two cavity corresponding apertures simultaneously, throttle blade is inserted and to be implemented positioning and fixing with screw after throttle plate pin divides the groove that is provided with on the axis body in inside cavity, so because throttle blade is so that the small angle inclination screens can only unidirectionally be rotated for the oval plate-like throttle blade of cutting sth. askew with the full capping state of cavity inner chamber the time; Twist mechanism is made up of the outer section of throttle plate pin axis body, torsion spring, rope support, initial corner location adjusting device, the outer section of closure axis body is linked in the level of the external side disjunctor of ante-chamber movingly and implements the fixedly connected of rope support with nut in the fit rope support endoporus on its outer end step axle of back in the axle sleeve endoporus, the rope support cylindrical is the annular groove body, and motor oil gas gate control handlebar is fixed on the accent of rope support annular groove body setting by the other end fit of a mild steel rope; Torsion spring is moving to be enclosed within the cavity level after joining forward on the sleeve outer circle, the torsion spring follower head is hooked on the extension pin of chamber outer wall, the torsion spring front end is hooked on the extension pin of rope support medial extremity setting, the torsion spring effect is rope support drive throttle plate pin, throttle blade is unidirectional executes when changeing, the rotation of drive torsion spring, when rope support did not have external force control, torsion spring impelled rope support, throttle plate pin, throttle blade return; Initial corner location adjusting device is to overlap a unification adjusting screw in a boss central, threaded hole on the preceding chamber outer wall, also be sheathed with locking nut on the adjusting screw, extend and a limit dais in the rope support inboard, when regulating throttle blade initial opening state, the limit dais end face is close to the end of adjusting screw under the effect of torsion spring power.
Air-flow is entered by the cavity intake duct, realizes air flow rate control by the throttle blade aperture.The fuel-flow control device then is to drive the stepping reset valve by stepper motor to implement flow control by the control oil channel flow, and the oil circuit mouth of pipe can be realized mixing of oil gas with choke valve air outlet channel pipeline connection, also can realize mixing with other form.
This kind choke valve defective is: when double-cavity conjoined processing supplies the through hole of throttle plate pin fit, this through hole length is long, the essential elongated tool of using, the long more beat degree of drill bit is big more, adding man-hour still more is three disconnected holes rather than a through hole, and drill bit always produces lateral deflection power when newly entering a disconnected hole planar ends.Then on the cavity diameter, the coaxality of through hole can produce deviation, throttle plate pin is long more, its add man-hour precision deviation is big too.Hole, shaft centre line deviation are big, break holes movingly for satisfying one and three, then to amplify the gap between the axle of hole in advance, the stack of the big and coaxiality deviation in gap, thereby two cavity throttle blade are when being regulated by same throttle plate pin, two throttle blade initial openings can produce deviation, and consequence is that two cavity air flow rates there are differences and can't regulate.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, provide a kind of motorcycle electric spraying two-chamber split type throttle-valve body.
The solution of the present invention is: preceding cavity rear axle housing and rear chamber front shaft sleeve disconnect and form split, the level with the chamber outer wall disjunctor of respectively being provided with in preceding cavity, rear chamber bi-side is to the tubulose connecting sleeve, other is provided with two sleeve pads between the cavity respective side connecting sleeve of front and back, two double threaded screws cooperate respectively be inserted in before and after in cavity homonymy connecting sleeve and the sleeve endoporus, lock on the outside thread of two screw rods with nut, cavity is fixedly connected before and after realizing; Throttle plate pin shortens fixedlys connected with a preceding force transmission rack behind the cavity before stretching out, and preceding force transmission rack is radial plate of a disk extension, and the disc centre borehole jack is combined in behind the throttle plate pin riveted fixing on the axle head step axle; Be sheathed with rear chamber closure rear axle movingly in the axle sleeve corresponding aperture before and after the rear chamber, back throttle blade is inserted the closure rear axle behind the groove that is provided with on the inside cavity part axis body, implements positioning and fixing with screw; Other is provided with the back force transmission rack, and back force transmission rack is radial plate of a disk extension, and the disc centre borehole jack is combined in the riveted fixing on the preceding axle head step axle of rear chamber closure rear axle; Be sheathed with torsion spring on the rear chamber front shaft sleeve, the torsion spring follower head is hooked on the extension pin of chamber outer wall, and the torsion spring front end is hooked on the force transmission rack radial plate of back, and torsion spring torsion direction is identical with torsion spring torsion direction on the preceding cavity; Preceding force transmission rack radial plate is provided with tapped hole, an adjusting screw is linked in this tapped hole, also be sheathed with locking nut on the adjusting screw, when regulating throttle blade initial opening state, the adjusting screw end before back force transmission rack radial plate one side on the rear chamber is close under the effect of torsion spring power on the preceding force transmission rack radial plate of cavity.
The invention has the advantages that: the solar term axle divides body structure that machining accuracy is improved, and makes two-chamber throttle blade aperture realize the split axle fine setting, and two throttle blade aperture conformity improve.
