Description
Technical field:
The utility model relates to the motorcycle electric spraying throttle-valve body, particularly big discharge capacity motorcycle electric spraying throttle-valve body.
Background technique:
The motorcycle electric spraying throttle-valve body is only controlled air mass flow at present, and 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 passes the cavity corresponding aperture, 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 cavity outside disjunctor 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 implement flow control by ECU 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.
Security when starting to walk in order to improve big discharge capacity motorcycle, 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 the cylinder end face of axis and cylndrical surface and bottom surface.This scheme makes throttle blade in the scope of rotation 0～19 degree, and throttle blade outer and arc surface spacing variable quantity 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 purpose of this utility model is to overcome above-mentioned defective, and a kind of big discharge capacity motorcycle electric spraying throttle-valve body is provided.
Scheme of the present utility model is: each fixes the wedged block of a symmetry on the reflecting surface of two semicircle opening directions of throttle blade, wedged block or solid body or with one side that throttle blade is fitted be the hollow recess body, wedged block is that angle summit angle is 16～20 degree with the throttle plate pin shaft axis; Between end face vertical and throttle plate pin, possess parallel distance in the wedged block with the throttle blade upper surface, wedged block outer face is two-way arc surface, each point meets the following conditions on the two-way arc shaped surface: when each point is in reference level, each point and distance between reference are less than intake duct cylindrical cavity radius 0.3～0.6mm, reference level refers to plane vertical with intake duct cylindrical cavity shaft axis and process throttle plate pin shaft axis, reference point fingering air flue cylindrical cavity shaft axis and throttle plate pin shaft axis intersection point; Wedged block is provided with two tapped holes, and two screws pass the corresponding through hole of throttle blade and implement fixedlying connected of wedged block and throttle blade.
Advantage of the present utility model is: wedged block is sharp processing, is guaranteed by mould-forming, and technology adds technology than inner cavity cambered surface to be simplified, and plays the air mass flow speedup equally and slows down effect, improves Security.
