Description
Technical field:
The utility model relates to carburetor structure, particularly the step motion control choke of Carburetor.
Background technique:
The Carburetor of motorcycle, universal machine is made up of body, float chamber, throttle valve device, choke etc.Body is arranged in air cavity the air-inlet cavity, the mixing chamber that are provided with connection, air enters after flowing through air-inlet cavity as the blending space mixing chamber, mixing chamber is air, fuel oil.Enter chock plate is installed, the cold startability of motor when chock plate is closed, can be improved.Closure is in mixing chamber, for controlling inflammable gas-flow.Throttle valve device is made up of torsion spring, throttle plate pin, throttle blade, lock screw etc.
Choke is made up of chock plate sheet, resistance sheet axle of the air door, twister.Chock plate plate shape is rectangular sheet, protrusion arc limit, and chock plate sheet area is less than body air-inlet cavity, a small amount of air inlet is had during to meet engine start, chock plate sheet is fixed on Air strangler spindle, and Air strangler spindle passes axis hole corresponding to body, is connected with a twister at body outer surface.Existing twister is made up of handle, gear pin.Handle upper portion is inverted L-shaped swing arm, lower portion thereof platform central hole is fixedly connected with Air strangler spindle injection moulding, lower portion thereof platform is provided with two chimbs in an angle of 90 degrees, gear pin is fixed on corresponding body outer surface, during rotatable handle, two chimbs limit by the gear pin be arranged on body, can only do 90 degree of rotations.
When engine cold starts, chock plate sheet is in full-shut position, vacuum up in chock plate sheet mixing chamber below, be conducive to motor and draw more fuel oil, a small amount of air is by the breach air inlet in chock plate sheet and body air-inlet cavity gap, and the inflammable mixture that air inlet amount little then mixed gas oil concentration height supply engine is denseer, is conducive to engine cold and starts, after starting, manual operation chock plate handle is disposable opens the 90 degree of redirects of chock plate sheet, enters nominal situation.The defect of this conventional construction is: control range is only confined to standard-sized sheet and full cut-off manually, the suitable opening and closing degree of chock plate can not be adjusted in real time according to the temperature variation of the operating point of engine running and motor, during artificial unlatching chock plate, often there is violent abnormal jitter phenomenon in motor, too early or cross and open chock plate late and all directly can cause engine misses, but also exist because people is misoperation and the engine consumption that causes or discharge value raise.
Separately there is a kind of of the choke flap structure being controlled chock plate aperture by bimetallic strip, although this structure can realize the automatic control of chock plate, but because this structure is the opening and closing that the resiliently deformable produced by the change of bimetallic strip induction generator cylinder temperature controls chock plate, by the impact of temperature transport velocity, the reaction time controlling chock plate opening and closing is slower, the opening and closing of chock plate often lags behind the working conditions change of motor, real-time control can not be carried out to chock plate, cause motor under the operating mode only needing rarer inflammable mixture, because chock plate unlatching is slow, Carburetor will supply the comparatively rich mixture of its quite a while, the rising of oil consumption and discharge value during causing this.
Current motor temperature transducer, speed probe, engine load sensor have been provided with.The PLC central processing unit (CPU) connection of three kinds of sensors and controller, PLC central processing unit (CPU) controls according to each data command controller, regulate the aperture of closure to reach optimal working point.How to make full use of these existence conditionses to realize chock plate Automated condtrol and smoothly open, close being the problem that the applicant researches and develops.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defect, provides the step motion control choke of Carburetor.
Scheme of the present utility model is: comprise chock plate sheet, resistance sheet axle of the air door, twister, also comprise the controller of motor, it is characterized in that: twister is made up of coupling, support, stepper motor, gear pin; Coupling cylindrical is stepped cylindrical shape, and its hypomere cylinder cylindrical is provided with arc notch, and gear pin is in empty in described arc notch and meets the following conditions: can make 90 degree of rotary limiteds to described arc notch; Coupling hypomere central blind hole is fixedly connected with Air strangler spindle upper end portion injection molding type, and coupling epimere offers rectangle blind slot; Support shape is the platform-like with two lower dome cylinders, and lower dome cylinder is provided with step hole, and the step hole that two screws are inserted in described rack platform respectively screws up in the boss tapped hole being fixed on the corresponding orientation of body, implements being fixedly connected with of support and body; Described rack platform is provided with walk through hole and two corresponding to Air strangler spindle orientation and installs tapped holes; Orthogonal flat side's shape is offered in the main shaft outer end of stepper motor, stepper motor main shaft be inserted in rack platform walk through hole after its main shaft outer end flat side of rectangle move to coordinate and be inserted in the rectangle blind slot of coupling, two bolts screw up after being each passed through two fixing hangers on stepper motor cylindrical to be fixed in two installation tapped holes corresponding on rack platform implements being fixedly connected with of stepper motor; The lighting outlet of stepper motor is connected with the controller line of motor.
The utility model has the advantage of: the chock plate step motion control structure of this technology can according to each different operating mode in the whole working procedure of motor, and the temperature variations that motor is different from cold to heat engine, control the on-off action of chock plate in real time accurately.Change that traditional craft is prominent opens prominent impatency throttle structure, realize chock plate be subject to the different change of engine speed, temperature, operating point and carry out step motion control on-off action in real time, chock plate opens and closes the sudden keying of non-moment, but the rotation seamlessly transitted opens and closes, mixed gas oil concentration is made also to be the sudden change of steady non sudden, reach the function controlling choke flap switch, the object of required best inflammable mixture under meeting the different operating mode of Carburetor supply engine, improves motor complete machine working stability performance.
