Description
Technical field
The utility model belongs to technical field of motorcycles, and specifically, particularly motorcycle with electronic fuel injection system is demarcated and used throttle actuator.
Background technology
Abgasgesetz in the face of increasingly stringent; Adopt electric jet technology reduction oil consumption and exhaust pollution imperative; Particularly for modern motorcycle, the application of electric jet technology can take into account economical, this 3 objective of raising motorcycle usability that reduces emission of harmful substances amount in the motorcycle exhaust, improves the engine operation simultaneously.Under the prerequisite that the software and hardware pattern of electric-control system is confirmed basically, whether engine has given play to best combination property, depends on that the optimization of matching of electric-control system and engine is demarcated.At present; The matching and calibration of motorcycle with electronic fuel injection system engine generally is performed such: at first by operating personnel the throttle grip on the handle pipe is turned an angle; And throttle grip is stabilized in this state through holding, meanwhile, throttle grip is through the acceleration cable dish on the acceleration cable pulling throttle body; Make throttle open certain angle and remain on this aperture state, by another operating personnel parameters such as engine gas-filling temperature, charging efficiency, fuel injection pulsewidth are measured then; After measuring completion, again throttle grip is turned over certain angle and firmly stable, proceed engine parameter and measure.By that analogy, until the engine parameter value of throttle under various apertures measured.The deficiency of above-mentioned demarcation mode is:
1) surveying work under each aperture of throttle need be stablized throttle grip about 10 minutes; Operating personnel must hold on to throttle grip with hand in the period at this section; Not only effort, labour intensity is very big, and operating personnel's hand shakes easily, can cause accelerator open degree to change; The minimum change that does not meet motorcycle calibration request accelerator open degree is no more than 0.15 regulation, and the accuracy of measurement is relatively poor.
2) must two operating personnel cooperate and could accomplish, labor cost is higher.
The utility model content
The utility model technical matters to be solved is to provide a kind of can guarantee that the demarcation of the accuracy of measurement result uses the throttle actuating unit.
The technical scheme of the utility model is following: the throttle actuating unit is used in a kind of demarcation; Comprise pedestal (1), front stall (2), back seat (3), guide pole (4), screw rod (5), handle (6) and slide block (7); Front end at pedestal (1) end face is fixed with front stall (2); The rear end of pedestal (1) end face is back seat (3) fixedly, is connected with two guide poles that are parallel to each other (4) between said front stall (2) and the back seat (3), between two guide poles (4), is provided with screw rod (5); This screw rod (5) is parallel to guide pole (4); The front end of said screw rod (5) passes front stall (2), and threaded engagement between screw rod (5) and the front stall (2), is fixed with handle (6) at the front end of screw rod (5); The middle part of the rear end of said screw rod (5) and slide block (7) is rotatably connected, and the two ends difference kink of slide block (7) is on two guide poles (4).
Adopt above technical scheme, the front end of acceleration cable and the slide block in the utility model fix, and the sleeve pipe of acceleration cable is fixed on the back seat in the utility model.When demarcating, operating personnel turn an angle with the hand control handle, and handle drives screw rod; Make screw rod with respect to front stall certain stroke that moves forward, because the rear end of slide block and screw rod is rotatably connected, and the two ends kink of slide block is on the guide pole of correspondence; Under the guiding function of guide pole, slide block is with screw rod certain stroke that moves forward, when slide block moves; Acceleration cable dish through on the acceleration cable pulling throttle body makes throttle open certain angle; After operating personnel's release handle; Under the threaded engagement of screw rod and front stall; The screw rod transfixion; Screw rod makes throttle remain on the aperture state of institute's open angle through slide block and acceleration cable, and this moment, operating personnel can measure parameters such as engine gas-filling temperature, charging efficiency, fuel injection pulsewidths; After measure accomplishing, again handle is turned over certain angle, make screw rod and slide block certain stroke that moves forward again, slide block is further opened throttle through acceleration cable, proceeds the engine parameter measurement.By that analogy, until the engine parameter value of throttle under various apertures measured.
This shows that the utility model needn't extra increase personnel be stablized throttle when carrying out the engine parameter measurement, only need operating personnel just can accomplish, not only simple to operate, easy to use, and saved the labour, reduced labour cost.The utility model can make throttle under each aperture, keep stable, and accelerator open degree changes when effectively having avoided measurement, and the minimum change that meets motorcycle calibration request accelerator open degree is no more than 0.15 regulation, has guaranteed the accuracy of measurement result.
Said front stall (2) and back seat (3) are " L " type, and are symmetricly set on the pedestal (1) of slab construction, and the horizontal component of front stall (2) and back seat (3) and the upper surface of pedestal (1) fit, through screw retention.Processing and fabricating is easy on the one hand, cost of manufacture is low for above structure; On the other hand, forward and backward seat is connected firm, easy accessibility with pedestal.Simultaneously, forward and backward seat is in the pedestal symmetric arrangement, the good stability of whole device.
For simplified structure, make things convenient for processing and fabricating and assembling; The end of said guide pole (4) front end is stretched in the front stall (2); The end of guide pole (4) rear end is stretched in the back seat (3); Rear and front end at guide pole (4) is provided with annular groove, and split washer (8) is installed in this ring mortise, and said guide pole (4) is by split washer (8) axial limiting.
Said handle (6) is a disc structure, simple in structure, be convenient to the operation; Handle is sleeved on flat side's section of screw rod (5) front end through the flat square hole at its center, and by nut lock, it is firm to be connected between handle and the screw rod like this, and handle can not relatively rotate with screw rod.
