Abstract
The utility model discloses a magnetic powder clutch for controllable sedan, which is composed of a clutch body, a coil is inserted in the clutch body, and a follower device is arranged at the inner side of the clutch body. The magnetic particles are filled in the working gap formed by the clutch body and the follower device, and an end cover is arranged outside the follower device. An electric pole is connected with the outgoing line of the coil. The magnetic powder clutch for controllable sedan has advantages of reasonable structure and perfect performance so as to realize that the clutch can fast and reliably separate and bond effectively or obtain an optimum slip moment of rotation, and the magnetic powder clutch for controllable sedan can enhance the service life of the engine and save energy. Furthermore, the automatic speed limiting is realized in automobile running.
Description
Technical field:
The utility model relates to a kind of automobile clutch.
Background technique:
Automobile clutch is a transmission part important in the automobile, its major function is to be the input power and the rotating speed of speed changer with the outputting power of motor and the rotating speed progress of disease, and has concurrently and reduce vibration, prevent to transship, guarantee automobile balance starting and the speed change function of gearshift smoothly.Existing automobile clutch is because there is certain defective in factors such as its structure at aspects such as service behaviour, working lifes.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the controllable type car magnetic powder clutch of favorable working performance.
Technical solution of the present utility model is:
A kind of controllable type car magnetic powder clutch, its feature: clutch body is arranged, coil is inlaid in the clutch body, the clutch body inboard is provided with driven member, magnetic was filled in the working clearance that clutch body and driven member constitute, driven member arranged outside end cap, electrode links to each other with finish lead.
Driven member has passive hub, and passive hub sleeve is contained on the splined shaft.Splined shaft is connected with damping spring.Electrode is the sliding ring type electrode.
The utility model is rational in infrastructure, and favorable working performance can realize effectively that the fast and reliable of clutch is separated, engage, or obtain best slippage torque, makes engine life raising, energy-conservation, makes automobile running realize automatic speed-limiting.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is an embodiment's of the utility model a configuration diagram.
Embodiment:
A kind of controllable type car magnetic powder clutch, clutch body 1 is arranged, coil 2 is inlaid in the clutch body 1, clutch body 1 inboard is provided with passive hub 3, passive hub 3 is sleeved on the splined shaft 4, and splined shaft 4 is connected with damping spring 5, and magnetic was filled in the working clearance 6 that clutch body and driven member constitute, passive hub 3 arranged outside end caps 7, sliding ring type electrode 8 links to each other with finish lead.
The utility model clutch body 1 constitutes the driving link of clutch, and passive hub 3, splined shaft 4 constitute the driven member of clutch.The effect of damping spring 5 is: when clutch because of torque changes impact force takes place, reduce change impacts power, guarantee the stationarity of automobile running, strengthened the fatigue strength of output shaft simultaneously, the working life of having improved clutch greatly.
Working principle of the present utility model is: when driving link produces rotation by the motor car engine drive, if there is not electric current in the coil, driving link rotates and the centrifugal force that produces can make magnetic press the internal surface that is attached to driving link so, driving link does not link to each other with driven member, clutch is in separated state, and automotive wheel is in a kind of unpowered drive condition.After coil passes to electric current, set up magnetic field at once, produce magnetic flux perpendicular to the working clearance.Magnetic flux arrives driven member along driving link by magnetic blow out coating, get back to driving link again by magnetic blow out coating then, make magnetic be linked to be magnetic linkage along the magnetic line of force, magnetic linkage is subjected to the magnetic pull effect of driving link to be skew trend, and magnetic is because magnetization produces magnetic force at intergranular, add the effect of the deskew shearing force that causes by mechanical force, thereby driven member is connected with driving link, and rotates with driving link, at this moment clutch is in jointing state.In this case, the power of motor is passed to driving wheel, overcomes running resistance, is driven automobile running by composition power trains such as clutch transmission, universal joint, transmission shaft ransaxles, therefore, in the car steering process, as long as make coil electricity or outage just can make automobile driving or do not drive.
