A kind of automobile clutchTechnical field
The present invention relates to automobile engine output device, be specifically related to a kind of automobile clutch.
Background technology
Clutch is the parts being directly associated with electromotor in car transmissions, and it is responsible for power and the cut-out of drive system and combination, it can be ensured that gentle start during vehicle starting, also can guarantee that smooth-going during gearshift, also prevent drive system overload.Widely used on automobile at present is exactly the friction clutch by spring compression.Automobile needs often to keep the transmission of power during travelling, interrupting power is temporary transient needs, therefore is actively chronically at bonding state, when driver's let slip the clutch with secondary part in the process of moving, by the transmission of parts, secondary part is allowed to separate with active part.
Clutch and clutch release bearing be produced heat during sliding wear, makes reduce the service life of clutch and clutch release bearing.In the engaging process of clutch, due to the existence of sliding wear, when often engaging one time, the most entirely produce substantial amounts of heat, and time of engaging is the shortest every time, the heat therefore produced cannot spread out of smoothly, causes friction plate temperature rise, life-time service meeting unstable wear, even can cause the scaling loss of friction plate and platen.There is hidden danger at casting process in clutch case, such as husky hole, pore, the density of foundry goods is inadequate, and tensile strength does not reaches requirement, and hardness is low etc. all can cause clutch case to occur explosion in high speed rotating uses.Clutch, as consumable accessory, the most effectively solves the problems referred to above, improves the service life of clutch, becomes problem anxious to be resolved.
Summary of the invention
The goal of the invention of the present invention is to overcome the above-mentioned deficiency of prior art, and provides a kind of easy to assembly, length in service life, reduction replacement cost, saves the automobile clutch of replacing construction.
Technical program of the present invention lies in: include active part, secondary part, pressing section, operating mechanism；Described active part includes flywheel, platen, clutch case；Described secondary part includes clutch plate, driven shaft；Clutch plate side is equipped with friction plate, described clutch case is built with resilient support circle, described bracing ring includes outer ring, inner ring and the multiple reinforcements being arranged between outer ring and inner ring, and outer ring is provided with damping trough and matches to position location link and the locating piece of bracing ring position with clutch case；Described clutch case is provided with and the stopper slot positioning link and locating piece matches；A louvre is had, equipped with more than one fin on louvre on described clutch case.
Described locating piece is more than one, is all distributed on the outer ring of bracing ring.
Described damping trough is multiple, is evenly arranged on the outer ring of bracing ring.
Described fin is spiral fin.
Described pressing section includes diaphragm spring, and diaphragm spring is truncated cone-shaped, including stub end and little head end, the little head end of diaphragm spring has a circle radial slot to form the card that a circle is connected.
Multiple louvre and radial direction radiating groove is set on described friction plate.
The positive and negative of described friction plate are equipped with radiating groove.
Owing to being provided with louvre and fin on clutch case, when automobile engine starting, owing to rotation and the fin of clutch rotate so that heat is shed in time, efficiently solves the sliding wear temperature rise between the Internal and external cycle of bearing, retainer, sealing ring, rolling element.Clutch can be in normal operation circumstances, extends its service life, saves replacing construction, reduces replacement cost.Location link and the locating piece of resilient support circle match with the stopper slot on clutch case, resilient support circle is made stably to be loaded on clutch case inwall, resilient support circle is easy for installation and removal by location link, the damping trough enclosed by resilient support is realized clutch case and is effectively supported in certain deformation range and buffer, strengthen the intensity of clutch case, overcome the difficult problem that explosion occurs in the use of clutch case.

Detailed description of the invention
In Fig. 1, the present invention includes active part, secondary part, pressing section, operating mechanism；Described active part includes flywheel, platen 8, clutch case 1.Secondary part includes clutch plate 4, driven shaft 6.Pressing section includes that diaphragm spring 7, diaphragm spring 7 are truncated cone-shaped, including stub end and little head end, the little head end of diaphragm spring 7 has a circle radial slot to form the card that a circle is connected.Clutch plate 4 side is equipped with friction plate 2, and clutch case 1, built with resilient support circle 3, clutch case 1 has a louvre 14, and equipped with spiral fin on louvre 14, area of dissipation is big, good heat dissipation effect.5 is ball bearing.
In Fig. 2, bracing ring (resilient support circle) 3 includes outer ring, inner ring and the multiple reinforcements 9 being arranged between outer ring and inner ring, and outer ring is provided with damping trough 10 and matches to position location link 11 and the locating piece 12 of bracing ring position with clutch case 1.Clutch case 1 is provided with and the stopper slot positioning link 11 and locating piece 12 matches.Resilient support circle is easy for installation and removal by location link, and in being hooked into stopper slot, limit can stably be fixed, and takes off location link 11, can disassemble bracing ring 3 from clutch case 1 inwall in stopper slot.
In Fig. 3, friction plate 2 sets multiple louvre 15 and radial direction radiating groove 16.
