Description
Technical field
The utility model discloses a kind of clutch, relate in particular to a kind of radiating fin on same clutch cover excessively under the drive of motor and produce wind-force, make clutch and clutch release bearing be in the unlikely heating of air-cooled state all the time.
Background technique
Automotive friction formula clutch has experienced the development course of last a century, several generations' wisdom and the stage that painstaking effort just arrive today have been merged, but effectively do not solve clutch driven plate all the time, the temperature arrising caused by friction between platen and the flywheel and the Internal and external cycle of clutch release bearing, retainer, seal ring, and the sliding wear temperature rise between the rolling element, and the Separation adjustment between clutch and the clutch release bearing is not good in the Installation and Debugging process, clutch separation is not thorough, the thermal distortion of the not enough and platen of platen lift, the operating habit that driver's quality is high and not bad, and the wearing and tearing stroke increase that separation refers to makes clutch be in half-clutch state for a long time, often cause that the clutch temperature rise is very high, after high temperature is delivered to clutch release bearing, make the lubricant grease that is sealed in the bearing cause grease to leak in a large number because viscosity reduces, make the clutch release bearing oil starvation and burn to death.So far remain one of principal element that causes clutch and clutch release bearing wearing and tearing, lost efficacy and even damage.Particularly passenger vehicle and city bus industry, the early stage damage of clutch and clutch release bearing have become general and distinct issues address this problem and arrived very urgent stage.
The heat that clutch and clutch release bearing are produced in the sliding wear process, influence in working life to clutch and clutch release bearing is very serious, from the process analysis of clutch work as can be known, in the engaging process of clutch, because the existence of sliding wear, all to produce a large amount of heat in every joint process once, and about short about 3S of each time that engages therefore heat have little time all to pass at all and go in the surrounding atmosphere, must cause the temperature rise of friction pair, using the clutch of working under the frequent and difficult condition, this temperature rise is just even more serious, it can cause that not only friction factor descends, aggravation wearing and tearing are when serious even can cause the scaling loss of friction plate and platen.Owing to the friction plate poor thermal conductivity made from asbestos or other organic substance, the heat that is produced in the sliding wear process is mainly absorbed by component such as flywheel and platens, temperature rise when making each engage is unlikely too high, absorbs heat so require platen to have enough big quality.Traditional design of platens is after preliminary definite platen thickness, checks clutch temperature rise once, should be above 8～10 ℃.If temperature rise is too high, can only suitably increase the thickness of platen.Owing to be subjected to spatial constraints.Still can not effectively solve the heat that clutch is produced in the sliding wear process.
From the process analysis of clutch release bearing work as can be known, same because the existence of sliding wear in the process that clutch release bearing engages, in the process that does not engage once, can not produce a large amount of heat yet, the clutch bearing of particularly normal contact-type is in high temperature, at a high speed, work under the high-intensity motion state for a long time, and this temperature rise is just even more serious.He not only can cause the increase friction torque and heat up, and makes bearing aggravation wearing and tearing or seizure.When bearing again rotated, the temperature of rolling element was than other part height, and its thermal expansion also will make the radial internal clearance of bearing and axial internal clearance reduce, and early damage take place and kill.Because the rotation of the disalignment of release bearing and clutch separation finger tip produces unbalance loading, release bearing generates heat easily under the effect of offset loading force and produces high temperature.Can cause also when serious that lubricant oil dissolves, runs off, evaporates the Internal and external cycle, retainer, the rolling element that cause release bearing too early and dry grinds and burn to death.At the clutch bearing that uses on the public transport passenger car of working under the frequent and difficult condition, this phenomenon is just more outstanding.So far also do not find effective solution both at home and abroad.
Summary of the invention
The purpose of this utility model provides a kind of air-cooled hot automobile clutch of spiral Lever type that looses automatically, utilizes the vehicle rotation of clutch radiating fin in the process of moving to produce wind-force, makes clutch and clutch release shaft be in the state of being cooled all the time; Thereby prolong the working life of clutch and clutch release bearing, reduce vehicle maintenance cost and cost of transportation.
Technological scheme according to the utility model provides has platen in clutch cover, release lever and holddown spring are arranged between clutch cover and platen; The outer end and the platen of described release lever are hinged, and the middle part is articulated on the clutch cover, and afterbody contacts with the eseparation ring that is positioned at the clutch cover center; A plurality of release levers evenly distribute on the circumferencial direction of clutch cover, and described holddown spring is characterized in that: on the outer wall of clutch cover radiating fin is set between adjacent two release levers.
