Description
Technical field
The utility model relates to a kind of clutch of automobile, is specifically related to a kind of electromagnetic clutch.
Background technology
The clutch that extensively adopts in the automobile all is the friction clutch with spring compression basically at present, and the flywheel of engine is the driving link of clutch, and the clutch plate that has friction plate is connected with the driving shaft of speed changer, and spring is pressed on clutch plate on the flywheel end face.Motor torque passes on the clutch plate by the frictional force between flywheel, clutch compressing disc and the clutch plate rubbing surface, thus transmission of power is gone down until wheel.The thrust of spring is big more, then clutch institute torque transmitted is also big more, along with infinite variable speed extensive use, the degree that requires automobile to control automatically is more and more higher, above-mentioned clutch more and more is not easy to automatic control, in addition, raising along with automobile dynamic quality, the moment of torsion that clutch transmitted is also increasing, therefore the inertia force of the secondary part of the thrust of spring and clutch is also increasing, this will cause clutch separation not thorough, and in conjunction with not soft, moreover fricative heat also can produce harmful effect to the work and the life-span of clutch.Slip clutch is formed the structure more complicated by parts such as clutch pedal, clutch master cylinder, clutch slave cylinder, flywheel, clutch driven plate, clutch cover plate, clutch pressure plate, clutch release bearing, clutch release forks.Its structure of Hydromechanical transmission is complicated more, and model vehicle of the same race requires than slip clutch height, and price is more expensive more than 3 times than slip clutch, and uses oil consumption also than higher.
The utility model content
The technical problem that the utility model quasi-solution is determined provides a kind of electromagnetic clutch.
To achieve these goals, the utility model adopts following technical scheme:
Electromagnetic clutch, it comprises magnetic bobbin core, coil, flywheel, clutch driven plate, bell housing, bell housing, clutch driven plate is fixed on the clutch spindle of gearbox, flywheel is fixed on the bent axle, coil and iron core are coated in the iron-clad and are fixed on the bell housing front end, gearbox is connected on the bell housing by bell housing, and above-mentioned flywheel outer ring is inboard to be slidingly matched with the clutch driven plate outer ring.
The electromagnetic clutch operation principle
When car engine start, flywheel is in rotary state with engine crankshaft, and not switching on because of electromagnetic clutch can not produce electromagnetic force, so clutch driven plate can not rotate with flywheel, bent axle separates with clutch spindle, gets in touch disconnection between engine and the driving wheel.
When automobile starting, by the current vortex that electromagnetic clutch energising back produces, make flywheel drive clutch driven plate and rotate together, make bent axle with progressively run-in synchronism of clutch spindle, guarantee the automobile balance starting.
When car gear shifting, by disconnecting the electromagnetic clutch power supply, make flywheel and clutch driven plate disconnect, bent axle separates with clutch spindle; After the gear shift, by the current vortex that electromagnetic clutch energising back produces, make flywheel drive clutch driven plate and rotate together that make bent axle with progressively run-in synchronism of clutch spindle, work is smooth-going when guaranteeing car gear shifting.
When automobile brake, by disconnecting the electromagnetic clutch power supply, make flywheel and clutch driven plate disconnect, bent axle is separated with clutch spindle, prevent the power train overload.
Outstanding effect of the present utility model is: it is simple in structure, installs also more conveniently, and clutch driven plate is lossless, under the control of Clutch Control computer K, makes vehicle starting, gearshift more simple and convenient during use; And when vehicle slides, by accelerator pedal sensor solenoid is quit work after throttle comes loose, promptly bent axle separates with clutch spindle, makes engine be in idling mode, to reach the fuel-economizing purpose.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Specific embodiments
The utility model is described in further detail below in conjunction with accompanying drawing 1:
Electromagnetic clutch, it comprises gearbox F3, clutch spindle Z2, magnetic bobbin core T, coil B, flywheel A, clutch driven plate G, motor body F1, bent axle Z1, clutch driven plate G is fixed on the clutch spindle Z2 of gear box casing F3, flywheel A is fixed on the bent axle Z1, magnetic bobbin core T is fixed on the F4, coil B is fixed on magnetic bobbin core T cylindrical, the outside at coil B and magnetic bobbin core T is coated with iron-clad F2, and inboard outer ring with clutch driven plate G, the outer ring of flywheel A is slidingly matched.
Electromagnetic clutch working method of the present utility model
1, engine start
Because of electromagnetic clutch is not switched on, so flywheel and clutch driven plate are not inhaled together, bent axle separates with clutch spindle, gets in touch disconnection between engine and the driving wheel; The ignition switch ato unit is to operating state.
2, parking starting
With the gearbox engage a gear, unclamp the pedal brake pedal, by the part work of brake pedal sensor at clutch working control circuit control coil B, it is stressed half discrete state that is in of flywheel A and clutch driven plate G part, the pedal of stepping on the throttle then, by accelerator pedal sensor coil B is progressively worked, rotate synchronously, guarantee the automobile balance starting until flywheel A, clutch driven plate G.
3, acceleration shifting
The accelerator pedal sensor that unclamps on the gas pedal quits work coil B, and bent axle separates with clutch spindle; The pedal of stepping on the throttle after the gear shift progressively works coil B by accelerator pedal sensor, and until rotating synchronously as flywheel A, clutch driven plate G, work is smooth-going when guaranteeing car gear shifting.
4, run up
The accelerator pedal sensor that unclamps on the gas pedal quits work coil B, even bent axle separates with clutch spindle; This moment, engine was in the idling work state, to reach the effect of fuel-economizing.
When 5, automobile emergency is braked
A: when sliding, the pedal brake pedal makes coil B work by engine sensor, when engine speed is lower than 800r/min, makes the coil B state that quits work by engine sensor, and bent axle separates with clutch spindle.
B: during normal operation, the pedal brake pedal when engine speed is lower than 800r/min, by brake pedal sensor, quits work coil B, and bent axle separates with clutch spindle, avoids engine overload.
When 6, travelling on the plateau
Switch is installed is made brake pedal sensor be in normally open, when automobile brake,, make coil B work make flywheel A, coil B engagement by brake pedal sensor; When flywheel A rotating speed is lower than 800r/min, by engine sensor, coil B is quit work, bent axle separates with clutch spindle, prevents the power train overload.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the technical solution of the utility model is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection range of the present utility model.
