Description

A kind of clutch case

Technical field

The utility model belongs to automobile clutch and manufactures and designs field, is specifically related to a kind of clutch case.

Background technology

Clutch plays vital effect in automotive transmission, not only plays power interruption and knotThe effect to power train overload protection is also played in the effect of closing. When the moment of torsion of engine transmission is greater than clutchWhen setting upper torque limit or having impact, clutch sliding wear, thus play the protective effect to power train, thisOne is particularly important while acting on automobile starting. When clutch sliding wear, friction plate heat-dissipating causes temperature to raise.If can not reducing, temperature will affect the life-span of clutch and the reliability of transmitting torque. So clutchHeat-sinking capability is also extremely important. For wet clutch, friction plate is immersed in lubricating oil, and friction is producedThe raw lubricated oil of heat is taken away, thereby has ensured friction plate temperature in the reasonable scope. And dry type clutchDevice is mainly cooling by air, and its cooling effectiveness depends primarily on clutch inner air mobility status. AirFlow faster, the heat of taking away is more, and the temperature of clutch friction plate is lower, and clutch performance is better.Otherwise Air Flow is slower, the heat of taking away is fewer, and the temperature of clutch friction plate is higher, clutchPerformance is poorer

Utility model content

The purpose of this utility model is to provide a kind of clutch that can improve automobile clutch heat dispersionLid.

For achieving the above object, the utility model provides following technical scheme: a kind of clutch case, bagDraw together discoid diapire, and the circular sidewall joining with bottom wall edge, on described sidewall away from diapireOne end be connected with the end face of coupling flywheel, described diapire, sidewall and flywheel jointly enclose hold fromClose the cavity of device parts, described diapire is provided with the centre bore passing for Clutch input shaft; Described sidewallWith on diapire, be respectively equipped with air admission hole and venthole, on described sidewall and/or diapire, be also provided with guide vane,In the time that housing rotates with flywheel, guide vane can make the interior generation of cavity flow from air admission hole to ventholeAir-flow.

Technique effect of the present utility model is: in the time that clutch rotates, and under the effect of guide vane,Clutch Outside air enters into clutch inside by air admission hole; Clutch inner air is again by giving vent to angerClutch is flowed out in hole. In clutch, form by this way the mobile circle of an air circulation, greatly increaseRadiating efficiency, make friction plate temperature stabilization in suitable scope, be conducive to improve the work of clutchMake stability; And then, because the radiating efficiency of the mobile circle of air circulation is high, on clutch case, leaveLouvre is relatively less, has improved to a certain extent the intensity of clutch case; And under same intensity,Realize the light-weighted requirement of clutch case.

Detailed description of the invention

As shown in Figure 1, 2, a kind of clutch case, comprises discoid diapire 10, and with diapire 10The circular sidewall 11 of side edge, on described sidewall 11 away from one end and the coupling flywheel of diapire 10End face connect, described diapire 10, sidewall 11 and flywheel enclose the chamber that holds clutch components jointlyBody, described diapire 10 is provided with the centre bore 15 passing for Clutch input shaft; Described sidewall 11 and the endOn wall 10, be respectively equipped with air admission hole 12 and venthole 13, on described sidewall 11 and/or diapire 10, also establishHave guide vane 14, in the time that housing rotates with flywheel, guide vane 14 can make to produce from entering in cavityPore 12 is to the mobile air-flow of venthole 13. In Fig. 1, direction shown in arrow is housing direction of rotation.In the time that clutch rotates, under the effect of guide vane 14, clutch Outside air enters by air admission hole 12Enter to clutch inside; Clutch inner air flows out clutch by venthole 13 again. With this sideFormula forms the mobile circle of an air circulation in clutch, has greatly increased radiating efficiency, makes friction plateTemperature stabilization, in suitable scope, is conducive to improve the job stability of clutch; And then, due to skyThe radiating efficiency of gas circular flow moving-coil is high, and the louvre leaving on clutch case is relatively less, necessarilyIn degree, improve the intensity of clutch case; And under same intensity, realize clutch case lightweightRequirement.
