Description
Technical field
The invention belongs to automobile gearbox Clutch Technology field, be specifically related to a kind of structural design of flat plate heat pipe type driving disc, improve the coefficient of heat transfer of rubbing surface in the clutch closing course.
Background technique
Clutch is a kind of device that transmits and cut off moment of torsion that extensively adopts in the automobile gearbox; Generally constitute driven dribbling friction lining face by the steel driving disc (flywheel, platen and reaction plate) of motor one side and the driven disc (friction disk) of output shaft of gear-box one side.Vehicle in starting on the slope, keep on the slope, rub in order to improve the cunning that property of automatic shft introduces; And in automatic transmission case, often advance to the joint of lock-up clutch and carry out under the less speed ratio ratio of input shaft rotating speed (the output shaft rotating speed with) etc. under the operating mode for improving fuel economy; Between driving disc and the driven disc because of the sliding relatively generation heat that rubs; Cause frictional surface temperature to raise, excessive temperature rise will make friction material aging in advance, cause the inefficacy of cooling effect decline and clutch.Therefore, the cooling of clutch friction face is all most important to its performance and long durability.
The cooling of dry clutch rubbing surface mainly is to absorb heat through the master metal Moving plate, because maximum heat produces and the endurance is all very short, and clutch is in closed state, is difficult to and the quick convection heat exchange of ambient air.Heat dissipating method commonly used is with increasing the friction disk diameter and adopting expensive friction material to improve the output torque of dry clutch.But this not only causes overweight driving disc design, and cooling effect Chang Wufa meets design requirement.The problem of rubbing surface cooling is the biggest problem that the dry clutch high pulling torque is used, and therefore, is necessary to adopt a kind of heat exchange method more efficiently.Generally speaking, the thermal conductivity ratio metal of friction material is low, and therefore most of heat can flow to the master metal Moving plate, if can in driving disc, adopt the phase transition heat technology then can improve cooling effect greatly.
Summary of the invention
The objective of the invention is: a kind of dry clutch of automobile gear box flat plate heat pipe type driving disc is provided, improves clutch friction face cooling effect, to improve dry clutch output torque, durability, reliability and efficient.
For achieving the above object; The technological scheme that adopts is: a kind of automobile gearbox is used flat plate heat pipe type driving disc for dry clutch; Comprise buckplate, flat board and capillary materials; It is characterized in that: the radial support muscle that said buckplate inboard is equipped with directly contacts with said planar surface, and said buckplate and flat board fuse along the mutual welded seal of perimeter outside, forms circumferential liquid collecting ring; Both sides or a side with the radial support muscle in the said liquid collecting ring are filled with capillary materials; Be equipped with radial groove between the inboard radial support muscle of said buckplate, form stream passageway between said groove and planar surface.
The inner capillary materials of filling of said circumferential liquid collecting ring is interconnected into the capillary materials of supporting rib both sides or a side filling and is one, and should be as far as possible near the external diameter of driving disc.
Described buckplate all can be fitted with driven disc with dull and stereotyped outer side plane and constituted rubbing surface.
The cross section of said radially stream passageway can be arbitrary shapes such as circle, rectangle, polygonal or triangle; Different stream passageways are at an end of inner radius; Can be apart from driving disc central axis different radii position; So that the width of stream passageway is remained on more than the certain value, principle is to make the radially outside flow resistance of steam unlikely too big.
The quantity of radial support muscle can equate or be unequal with the quantity of stream passageway radially.
Said radial capillary material, stream passageway and supporting rib arrange it can is straight line type radially, also curved, so long as an end of stream passageway is near internal diameter, the other end gets final product near external diameter.
Said work medium for heat pipe can be water or other any suitable material of liquid that is at normal temperatures, as long as be lower than 350 ℃ in the phase transition temperature of the following liquid phase of 10 barometric pressure to vapour phase.When driving disc is made, a certain amount of working medium is injected stream passageway in advance.
Good effect of the present invention is: the heat that produces on the frictional interface reaches capillary materials through plate heat conduction; Working medium (purified water) evaporation that capillary materials (sintered powder metal) is included; This water vapor is at stream passageway and cryosurface convection heat exchange, and cryosurface reaches peripheral air through transmission of heat and convection heat exchange with heat again.Water vapor is after the cryosurface inboard condenses into water; Rotate the action of centrifugal force that produces owing to driving disc; Liquid water is collected (among Fig. 1 shown in the dotted line) by capillary materials at the peripheral liquid collecting ring of driving disc; And radially infiltrate into (shown in Fig. 1 cathetus) near the internal diameter of separator disc from outside to inside by the capillary force of capillary materials, absorb heat.So circulation promptly constitutes cooling system efficiently.The present invention has greatly improved the heat transfer problem that the dry clutch cooling is faced, and on flywheel, platen and the reaction plate that the friction surface with the driven disc both sides contacts, uses simultaneously, can make the maximization of heat radiation cooling effect.
