Description

A kind of centrifugal clutch

Technical field

The present invention relates to mechanically operated centrifugal clutch; The centrifugal clutch of automobile-use particularly.

Background technique

The combination of centrifugal clutch, is the centrifugal force producing while utilizing centrifugal parts to rotate, and promotes clutch bonded block and mutually combines; When centrifugal component speed is less than certain certain value, because the centrifugal force producing is not enough, make to promote the combination force deficiency of clutch bonded block, and make centrifugal clutch in separated state, this rotating speed is called the separated rotating speed of centrifugal clutch.Current centrifugal clutch can only be realized its separation under a certain fixing rotating speed (separated rotating speed), once rotating speed higher than this separation rotating speed, centrifugal clutch, under the driving of centrifugal force, will carry out combination automatically; But in actual applications, need centrifugal clutch to there is different separated rotating speeds; As vehicular engine not only need centrifugal clutch when the idling in separated state, and need to be at " fast-idle speed " states such as warming up, air-conditionings, also require the centrifugal clutch should be in separated state, to carry out gear shift operation at " fast-idle speed " state; Therefore industry need to a kind ofly can, at different rotating speeds, realize the centrifugal clutch of clutch separation.

Summary of the invention

The object of the invention is the problems referred to above that exist for centrifugal clutch, provide a kind of and can, at different rotating speeds, realize the centrifugal clutch of clutch separation.

The object of the present invention is achieved like this; A centrifugal clutch, comprises the compositions such as clutch frame, centrifugal clutch and electromagnetic chuck, sucker controller, power supply; Wherein centrifugal clutch comprises initiatively transmission part, driven transmission part, centrifugal parts; Described active transmission part comprises driving shaft fixed block and driving shaft moving part; Driving shaft moving part is arranged on driving shaft fixed block, rotates, and can move relative to driving shaft fixed block with driving shaft fixed block; Described centrifugal parts are arranged on active transmission part, with active transmission part, rotate, and can move relative to active transmission part, and the movement of centrifugal parts, can make centrifugal parts drive driving shaft moving part close to driven transmission part, impel the combination of driving and driven transmission part; Described centrifugal clutch is arranged in clutch frame by bearing; The invention is characterized in: between driving shaft moving part and clutch frame, electromagnetic chuck is set, or between centrifugal parts and clutch frame, electromagnetic chuck is set; And electromagnetic chuck is fixed in clutch frame; Make the mounting point of electromagnetic chuck near driving shaft moving part simultaneously, be beneficial to the magnetic attraction driving shaft moving part disengaging of electromagnetic chuck generation and the combination of driven transmission part; Or make the mounting point of electromagnetic chuck near centrifugal parts, be beneficial to the centrifugal parts of magnetic attraction that electromagnetic chuck produces, thereby stop centrifugal parts to drive driving shaft moving part to be combined with driven transmission part; Described sucker controller and power supply are installed in clutch frame, wherein sucker controller is one to have detection, analyze " initiatively transmission part rotating speed " and " separated speed demand signal " function, and has the control state that opens and closes of electromagnetic chuck and the control gear of magnetic force size; Described power supply, for electromagnetic chuck and sucker controller provide electric power; Described electromagnetic chuck, sucker controller and power supply, connect by wire.

The principle of the invention: when centrifugal clutch turns round, sucker controller detects constantly, analyze initiatively transmission part rotating speed and " separated speed demand signal ", when sucker controller receives, need to make centrifugal clutch " separated rotating speed " signal in separated state at a certain rotating speed " time, just start to judge current active transmission part rotating speed, when active transmission part rotating speed reaches " separated rotating speed ", sucker controller is by electromagnetic chuck and power connection, make electromagnetic chuck produce magnetic force, to attract driving shaft moving part, stop it to be combined with driven transmission part, or attract centrifugal parts, stop centrifugal parts to drive the combination of driving shaft moving part and driven transmission part, thereby it is separated in the pressure of this " separated rotating speed " to realize centrifugal clutch, sucker controller can be controlled the size of electromagnetic chuck magnetic force according to different separated rotating speed requirements, thereby it is separated in the pressure of different rotating speeds state to realize centrifugal clutch, when sucker controller receives when removing clutch and forcing " the separated ring off signal " of separated state, sucker controller will disconnect between electromagnetic chuck and power supply, and magnetic force disappears, centrifugal clutch return to self original from, close characteristic state.
