Embodiment
As Fig. 1, Fig. 2 and the expressed structure of the present utility model of Fig. 3, the utility model is a kind of motor car engine accessory wheel system, be provided with generator 4, its generator shaft 2 is provided with generator pulley 1, and be connected with fan pulley 6 by drivign belt 5, generator 4 is by blower pulley 6 transmissions, be that blower pulley 6 is driven wheel for driving wheel, generator pulley 1, by drivign belt 5 transmissions, motivational drive generator 4 generatings that engine crankshaft rotation produces are for the power supply system of car load provides electric power as igniting system, illumination system and other power device.
Owing to generator 4 can torsional oscillation take place because of the variation of output electric weight and engine speed in the course of the work,, just can't stop this torsional oscillation to pass to bent axle if generator pulley 1 is rigidly connected with generator shaft 2.Torsional oscillation that like this will generator increases the noise of motor, influence the stability and the smoothness of accessory wheel system, the working life of reduction accessory wheel system even whole motor.In order to address this problem, the technological scheme that the utility model proposes is: between the endoporus of the cylindrical of generator shaft 2 and generator pulley 1, be provided with overrunning clutch 3, overrunning clutch 3 is a ring, and form by the outer ring 10 and inner ring 9 suits of ring, the interior circle of the cylindrical of its inner ring 9 and outer ring 10 is a Spielpassung, establish the one way engagement structure between described outer ring 10 and the inner ring 9, described inner ring 9 and generator shaft 2 are for being fastenedly connected, and described outer ring 10 and generator pulley 1 are for being fastenedly connected.When driving generator pulley 1 by drivign belt 5, blower pulley 6 rotates, the inner ring 9 of overrunning clutch 3 and outer ring 10 engagements at this moment, and generator pulley 1 drives generator shaft 2 and rotates, generator 4 generatings.Engine speed slow down, stop or even counter-rotating, overrunning clutch 3 just can disengage from, the torsional oscillation of generator 4 generations is isolated the influence of motor.In the normal working of engine process,,, very little to the influence of motor then owing to be identical with the direction of load if generator 4 produces the torsional oscillation with the driving switched in opposite of generator pulley 1; Turn to identical torsional oscillation if generator 4 produces with the driving of generator pulley 1, this torsional oscillation is the most harmful, but because overrunning clutch 3 disengage from make torsional oscillation can not exert an influence to motor.
First embodiment that the utility model is proposed on the basis of technique scheme is:
As shown in Figure 2, overrunning clutch 3 is the override type overrunning clutch, above-described one way engagement structure is to establish breach 7 on the cylindrical of the inner ring 9 of overrunning clutch 3, breach 7 is made of two mutually perpendicular planes, one of them plane parallel is in the axis of the inner ring 9 of overrunning clutch 3, the extended surface on another plane and this dead in line, in breach 7, establish rolling element 8, when rolling element 8 and above-mentioned two plane contact, its profile does not exceed the periphery of the inner ring 9 of overrunning clutch 3, between the plane of passing through axis on rolling element 8 and the described breach 7, be provided with rolling element stage clip 11.The direction of representing by Fig. 2, when generator pulley 1 counterclockwise rotated, rolling element 8 is between the surface that is pushed to inner ring 9 and outer ring 10 under the effect of rolling element stage clip 11, and was and crowded more tight more, realizes engagement; Otherwise disengage from then.
Be to realize engagement more reliably, the breach 7 of present embodiment can be more than one, and uniform on the circumference of the cylindrical of inner ring 9, the opening direction unanimity of each breach 7.Stressed so more even, the area of contact of engagement is bigger, and the load that plane on each breach 7 and rolling element 8 bear is littler.
Second embodiment that the utility model is proposed on the basis of aforementioned techniques scheme is:
As shown in Figure 3, overrunning clutch 3 is a click formula overrunning clutch, its one way engagement structure on the whole internal circular surfaces of the outer ring 10 of overrunning clutch 3, establish a plurality of along it in the uniform ratchet 12 of round Zhou Fangxiang, each ratchet 12 is made of two crossing planes, one of them plane is facing directly by the axis of outer ring 10, another plane is the inclined-plane, the true dip direction of all ratchets 12 is consistent on round week in outer ring 10 whole, on the inner ring 9 of overrunning clutch 3, establish ratchet 13, ratchet 13 is connected for shipping and reselling on another market with inner ring 9, ratchet 12 engagements when ratchet 13 rotates to a limit position and on the outer ring 10 of overrunning clutch 3, when ratchet 13 rotates to another limit position, its profile does not exceed the cylindrical of inner ring 9, establishes ratchet stage clip 14 between ratchet and inner ring 9.By the direction that Fig. 3 represents, when generator pulley 1 clockwise direction rotated, ratchet 13 was realized engagement in ratchet stage clip 14 is pushed to the spill of ratchet 12; Otherwise ratchet 13 is pushed back by ratchet 12 in the groove of inner ring 9, disengage from.
Be to realize engagement more reliably, the ratchet 13 of present embodiment can be more than one, and uniform at the circumferencial direction of the outer round surface of inner ring 9.Stressed so more even, the area of contact of engagement is bigger, and the load that each ratchet 13 and ratchet 12 bear is littler.
The 3rd embodiment that the utility model is proposed on aforesaid two embodiments' basis is:
For more convenient processing, reduce the complexity of whole motor piece wheel train structure, described outer ring 10 is as a whole with generator pulley 1.It is the junction plane that the endoporus of generator pulley 1 directly is taken as override type overrunning clutch outer ring; Perhaps the endoporus with generator pulley 1 is processed into ratchet 12.
The utility model adopts technique scheme, the torsional oscillation that automobile current generator is produced can not produce injurious effects to the bent axle and even the whole motor of motor car engine, reduce the noise and the vibration of motor car engine accessory wheel system, improve the stability and the life-span of motor car engine.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
