Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.Should be understood that, embodiment described herein, only for instruction and explanation of the present invention, is not limited to the present invention.
See Fig. 1, the invention provides a kind of friction clutch, described friction clutch comprises clutch cap 6 and is arranged on the wheel hub 1 of inside of this clutch cap 6, described wheel hub 1 is connected with multiple flywheels 2 of spaced setting and described flywheel 2 can move between described wheel hub 1 and described clutch cap 6 along the radial direction of described wheel hub 1, the outer circumferential face of described flywheel 2 is provided with friction plate 4, is connected by elastic recoil part 3 between adjacent two described flywheels 2.
When wheel hub 1 rotates, be arranged on the effect outwards movement of the flywheel 2 on wheel hub 1 peripheral part due to centrifugal force.When wheel hub 1 rotational velocity is more and more faster, centrifugal force continues to increase, and makes flywheel 2 be subjected to displacement peripheral part away from wheel hub 1 further.Now, be arranged on friction plate 4 on flywheel 2 peripheral part simultaneously near clutch cap 6 inwall until the two contact, produce stiction between friction plate 4 and clutch cap 6, thus clutch cap 6 is jointly rotated with friction plate 4 under the effect of this stiction, reach the object of combination.After wheel hub 1 rotational speed declines, centrifugal force weakens, and flywheel 2 sets back, and the combination between friction plate 4 and clutch cap 6 separately.And the elastic recoil part 3 connected between friction plate 4 can make whole friction clutch obtain better stability, make the movement of flywheel 2 and reply better effects if.
In order to when making wheel hub 1 High Rotation Speed, its center of rotation remains unchanged, and when flywheel 2 rotates, the friction plate 4 be connected on flywheel maximizes with clutch cap 6 area of contact, can obtain the frictional force that a size is stable, preferably by described wheel hub 1 and described clutch cap 6 concentrically axis.Like this, even if when High Rotation Speed, the distance between wheel hub 1 and clutch cap 6 also can keep stable always, and the movement locus of flywheel 2 in clutch cap 6 is fixed, and friction plate 4 is constant with clutch cap 6 area of contact, and the friction effect obtained keeps good.
Friction plate 4 is mainly used for carrying out contact friction with the inwall of described clutch cap 6, and utilize frictional force to drive described clutch cap 6 to rotate together, therefore the friction effect of friction plate 4 is just very important.In actual use, due to frequent contact friction, the loss of friction plate 4 is very fast, timing is needed to change, convenient and swift in order to change, preferably, also be provided with joint 5 between described flywheel 2 and described friction plate 4, described elastic recoil part 3 is connected with described joint 5.Like this, when contact friction DeGrain, more renewal of facing renewal 4 is with regard to more convenient and quicker.
In total, require that described joint 5 has fixed structure, not easily under the impact of larger centrifugal force, deformation occurs, damage Integral connection structure, typically, described joint 5 is stalloy.
Same, because friction plate 4 and described clutch cap more than 6 time or Long contact time friction can produce heat, if good radiating effect can not be had, be easy to make the inside temperature of described clutch cap 6 too high, damage device.Therefore, described friction plate 4 not only needs the ability of rub resistance, also needs to have good heat dispersion, the situation of comprehensive two aspects, and preferred described friction plate 4 is ceramic plate.Moreover, in order to obtain better radiating effect, multiple radiation hole can also be provided with on described wheel hub 1.
When clutch high speed rotating, centrifugal force is increasing, flywheel 2 externally move until be fitted in described clutch cap 6 inwall on rub, when rotational velocity lowers, need the parts of secondary flywheel 2 resile, make clutch cap 6 internal structure keep stable, therefore preferably, the two ends of described joint 5 are respectively arranged with through hole, and described elastic recoil part 3 is articulated in by the hook at two ends in the described through hole of the opposite end of adjacent described joint 5.In order to the slewing area that makes flywheel 2 further and the frictional force that provides in the same size, further preferably, described elastic recoil part 3 arranges multiple described through hole respectively with the two ends of described joint 5 and the quantity of described through hole is identical.
Area of contact size between flywheel 2 and clutch cap 6 directly can have influence on the size obtaining frictional force, if described flywheel 2 being set to a circular entirety is set on wheel hub 1, even if so obtain larger frictional force, also the raw thermogenetic heat of clutch cap 6 internal friction can be made excessive simultaneously, comprehensive reach desired by the two can obtain larger frictional force and can reach good radiating effect again, therefore flywheel 2 is arranged to circular shape, and preferably, described flywheel 2 is 2.
The present invention also comprises a kind of friction clutch drive mechanism, this friction clutch drive mechanism comprises above-mentioned friction clutch and driving shaft and driven member, described driving shaft is connected with the described wheel hub 1 of friction clutch and drives described wheel hub 1 to rotate, and described driven member is connected with the described clutch cap 6 of friction clutch and can follows described clutch cap 6 and move.
The present invention also comprises a kind of vehicle, and this vehicle comprises above-described friction clutch drive mechanism.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned mode of execution; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technological scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition, each concrete technical characteristics described in above-mentioned embodiment, in reconcilable situation, can be combined by any suitable mode, in order to avoid unnecessary repetition, the present invention illustrates no longer separately to various possible compound mode.
In addition, also can carry out combination in any between various different mode of execution of the present invention, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
