Description
Technical field
The utility model relates to a kind of technical field of automobile, particularly relates to a kind of automobile clutch.
Background technique
Friction clutch applies the most also be a history class clutch at most, and it is become with operating mechanism four part group point by active part, secondary part, hold-down mechanism substantially.Driving and driven part and hold-down mechanism ensure that clutch is in jointing state and the basic structure of energy transfer motion power, and the operating mechanism of clutch mainly makes the device of clutch separation.
Engine flywheel is the driving link of clutch, and driven disc body and driven hub with friction plate borrow free-sliding spline to be connected with driven shaft (i.e. the driving shaft of speed changer).Driven disc body is then pressed on flywheel end face by holddown spring.Engine torque namely by between flywheel and driven disc body contacts face rubbing action and pass on driven disc body, more thus in driven shaft and power train a series of parts pass to driving wheel.The impacting force of holddown spring is larger, then the torque that can transmit of clutch is also larger.
Due to automobile in the process of moving, often need keep transmission of power, and to interrupt transmission be temporary transient needs, therefore the active part of automobile clutch and secondary part are often in jointing state.Friction pair adopts spring attachment to be namely to adapt to this requirement.When wishing clutch separation, as long as step on the pedal in clutch operation, the shift fork be enclosed within the annular groove of driven disc body hub just promotes the pressure that driven disc body overcomes holddown spring and moves to the direction of unclamping, and with divided flywheel from, frictional force disappears, thus has interrupted the transmission of power.
When needs recover transmission of power again, change more steady for making car speed and engine speed, should the suitable solenoidoperated cluthes pedal speed of ging up, make driven disc body under the effect of holddown spring pressure, move resume contacts to the direction engaged with flywheel.Pressure between the two surface of contact increases gradually, and corresponding friction torque also increases gradually.When flywheel and driven disc body engagement are also not tight, when friction torque is smaller therebetween, the two can asynchronously rotate, and namely clutch is in slipping state.Along with the progressively increase of flywheel and driven disc body engagement tightness degree, the two rotating speed is also gradually equal.Until when clutch engages completely and stops skidding, car speed can be directly proportional to engine speed.
The peak torque that friction clutch can spread out of depends on the maximum static friction moment between rubbing surface, and the latter is determined by impacting force maximum between rubbing surface and rubbing surface size and character.Therefore for the clutch of a fixed structure, static friction torque is a definite value, and input torque one reaches this value, and clutch will skid, and thus limits power train institute torque suspension, prevent overload.First be under the prerequisite ensureing Transmission Engine peak torque, meet two Essential Performance Requirements, be namely separated thoroughly and engage soft;
Secondly, the rotary inertia of clutch secondary part is little as far as possible.If this rotary inertia is large, when shifting gears, although owing to being separated clutch, make to contact disengagement between motor and speed changer, but the moment of inertia that clutch secondary part is larger still inputs to speed changer, its effect is equivalent to be separated thorough, just can not play well and act on alleviating the impact of wheel between cog.
In addition, clutch is also required to dispel the heat good.Because in vehicle traveling process, pilot control clutch ground number of times is a lot, and this just makes in clutch due to relative sliding wear and produce a large amount of underground heat continually between rubbing surface.Clutch engages softer, produces geothermal flow larger, and these heats, as shed not in time, work generation seriously to be affected clutch.Friction member is the main element of friction clutch, and the physical property of its work surface material and mechanical property directly affect the service behaviour of clutch.To the major requirement of material be: friction factor is large and stable, and the coefficient of kinetic friction should be as far as possible close with static friction coefficient; Intensity is high, can withstand shocks, and not easily breaks and peel off during high speed; Wear-resisting, high temperature resistant, corrosion-resistant and good heat conductivity, thermal distortion is little; Should unlikelyly be adhered when leaving standstill for a long time.In addition, also long service life is required, easily processing and inexpensive etc.Conventional rubbing contact-material has powdered metallurgical material, asbestos sill and paper base material.Powdered metallurgical material: under surperficial allowable temperature, allowable pressure, high temperature, friction factor and life-span are all higher.Copper based powder metallurgy material is mainly used in wet friction face, and iron-base powder metallurgy material friction factor and allowable pressure all comparatively copper base are high, but wear resistance is lower, is used for dry type rubbing surface.Asbestos sill: add binder with asbestos and filler mold pressing forms, be cemented on steel or iron bottom plate, allowable work temperature is lower.Paper base material: be interweaved with asbestos, vegetable fiber or both mixtures.
Current existing clutch configuration is complicated, runs stable not, and comparatively large to the wearing and tearing of friction plate, working life is not long.
