Abstract
The invention discloses an electric spraying air throttle body of a large displacement motorcycle, relating to an electric spraying air throttle body of a motorcycle. The electric spraying air throttle body comprises a cavity, an air throttle plate in the cavity, an air throttle shaft and a twisting mechanism. The electric spraying air throttle body is characterized in that two symmetrical wedge-shaped blocks are respectively fixed on the reverse surfaces of two semicircular opening directions of the air throttle plate, and the angle of the wedge-shaped blocks, with the axis of the air throttle shaft as the peak of an included angle, is 16-20 DEG; the external edge surfaces of the wedge-shaped blocks are bidirectional circular surfaces, and each point on the bidirectional circular surfaces meets the following conditions that: when each point is in a reference plane, the distance between each point and a reference point is 0.2-0.6 mm less than the radius of a cylindrical cavity of an air duct, wherein the reference plane is the plane perpendicular to the axis of the cylindrical cavity of the air duct and passing through the axis of the air throttle shaft, and the reference point is the intersection point of the axis of the cylindrical cavity of the air duct and the axis of the air throttle shaft; two screws are used for fixedly connecting wedge-shaped blocks and the air throttle plate after passing through the through hole corresponding to the air throttle plate. The invention has the advantages that the wedge-shaped blocks are profiled, and the process is simplified.
Description
Technical field:
The present invention relates to the motorcycle electric spraying throttle-valve body, particularly big discharge capacity motorcycle electric spraying throttle-valve body.
Background technique:
A present motorcycle electric spraying throttle-valve body control air flow, the air throttle structure is made up of throttle blade, the throttle plate pin of fixed knot bulla, twist mechanism in cavity, the cavity; Cavity geometry air-flow intake duct is a cylindrical cavity; The air-flow air outlet channel is a diffusing opening conical cavity outwardly; Having horizontal axle sleeve to pass intake duct for throttle plate pin on the cavity is enclosed within the axle sleeve hole movingly; Throttle blade is the oval plate-like of cutting sth. askew; After a throttle plate pin passed the cavity corresponding aperture, throttle blade was 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 level that the outer section of closure axis body is linked in cavity outside disjunctor is movingly implemented the fixed connection 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 through 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, and the torsion spring effect is rope support drive throttle plate pin, throttle blade is unidirectional executes when changeing, and drives the torsion spring rotation; 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 got into by the cavity intake duct, realizes air flow rate control through the throttle blade aperture.The fuel-flow control device then is to implement flow control by ECU through 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.
Security when starting to walk in order to improve big discharge capacity motorcycle; One Chinese patent application number 200510022358.5 " electric injection gas saving valve for motorcycle " disclose a kind of technological scheme; This scheme is to the effect that: the body intermediate section cavity shape that cooperates with throttle blade is that two, a cylndrical surface connects an arc surface that size is identical respectively, and this cylndrical surface and two arc surfaces all rotate with same axis and form; Two centers of circle of this two arc surface lay respectively on the intersection point of cylinder end face and bottom surface of axis and cylndrical surface.This scheme makes throttle blade in the scope of rotation 0～19 degree, and throttle blade outer and arc surface changes in spacing amount increment slow down, and just the air mass flow speedup is slowed down, and has improved Security.But these two non-isometrical arc surface technology difficulty of processing are big in the solar term cavity, and its shape, precision are difficult to reach requirement.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, a kind of big discharge capacity motorcycle electric spraying throttle-valve body is provided.
Scheme of the present invention is: each fixes the wedge of a symmetry on the reflecting surface of two semicircle opening directions of throttle blade; Wedge or solid or with one side that throttle blade is fitted be the hollow recess body, wedge is that angle summit angle is 16～20 degree with the throttle plate pin axial line; Possess parallel distance between end face that the interior edge of wedge is vertical with the throttle blade upper surface and the throttle plate pin; Wedge outer face is two-way arc surface; Each point meets the following conditions on the two-way arcwall face: when each point is in datum level; Each point and distance between reference are less than air intake duct cylindrical cavity radius 0.3～0.6mm, and datum level refers to plane vertical with air intake duct cylindrical cavity axial line and process throttle plate pin axial line, datum mark fingering air flue cylindrical cavity axial line and throttle plate pin axial line intersection point; Wedge is provided with two screwed holes, and two screws pass the corresponding through hole of throttle blade and implement fixedlying connected of wedge and throttle blade.
The invention has the advantages that: wedge-shaped blocks is sharp processing, is guaranteed by mould-forming, and technology is simplified than inner cavity cambered surface process, plays the air mass flow speedup equally and slows down effect, improves Security.
