Abstract
The invention relates to a diaphragm type spring clutch. The diaphragm type spring clutch comprises a pressing plate, a clutch cover, a diaphragm, an inner supporting ring, an outer supporting ring and a plurality of diaphragm rivets, wherein the diaphragm rivets are uniformly distributed in the circumferential direction, shoulders are arranged at the left ends of the diaphragm rivets, pointed bulges with tooth tops facing rightwards are arranged on the right end surfaces of the shoulders, concave arc surfaces are arranged on the pointed bulges, the diaphragm rivets are used for sequentially connecting the inner supporting ring, the diaphragm, the outer supporting ring and the clutch cover together from left to right, and the concave arc surfaces on the diaphragm rivets are tightly attached to the inner supporting ring; the diaphragm comprises a diaphragm spring main body and separation fingers which are uniformly distributed on an inner ring of the diaphragm spring main body, and reinforcing ribs which are upwards convex are respectively arranged at the centers of the separation fingers along the radial direction. The diaphragm type spring clutch disclosed by the invention is simple in structure, convenient to assemble, disassemble and maintain, capable of overcoming the defect of large idle stroke of a clutch assembly and reducing a separating force of the clutch assembly, high in production efficiency, low in cost, safe and reliable.
Description
Technical field
The present invention relates to clutch field, particularly relate to a kind of automobile film chip type spring clutch.
Background technique
Clutch is by friction plate, spring diaphragm, platen and pto＝power take-off composition, be arranged between motor and gearbox, the moment that engine flywheel stores is used for pass to gearbox, ensure that vehicle passes to the appropriate driving force of driving wheel and moment of torsion under different running condition, belong to the category of power assembly.Existing diaphragm-type automobile clutch is made up of platen, clutch cover, diaphragm, internal support ring and external support ring, clutch cover is provided with several circumference is uniform and turns over tongue, when internal support ring is installed, adopt the tongue press-bending of turning over of clutch cover to be loaded between clutch cover and diaphragm by internal support ring, assembling work amount is larger, efficiency of assembling is lower, and internal support ring easily ruptures, and dismantlement work amount is large.And normal film flat spring separation finger poor rigidity, causes that the invalid release travel of clutch assembly is large, platen lift is little, Separating force is large, ensures that the reliability of mechanical property is lower.On car load, there are pedaling force weight, gearshift difficulty, the problem of clutch early failue simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to provide that a kind of structure is simple, mounting or dismounting are convenient and the diaphragm type spring clutch that safety reliability is high.
The technological scheme that the present invention solves the problems of the technologies described above is as follows: a kind of diaphragm type spring clutch, comprise platen, clutch cover, diaphragm, internal support ring and external support ring, also comprise the diaphragm rivet that several circumferences are uniform, the left end of described diaphragm rivet is provided with shoulder, the right side of described shoulder is provided with the pointed projection of crown towards the right side, described pointed projection is provided with concave arc surface, described diaphragm rivet is successively from left to right by described internal support ring, described diaphragm, described external support ring and described clutch cover link together, and the described concave arc surface on described diaphragm rivet and described internal support ring are adjacent to, to guarantee when internal support environment-development life is ruptured, internal support ring can not come off from diaphragm-type automobile clutch, the safety and reliability of diaphragm-type automobile clutch can be improved.
Preferably, the radius of the described concave arc surface on described diaphragm rivet, slightly larger than the steel wire radius of described internal support ring, when the steel wire diameter of internal support ring has error, still can ensure that concave arc surface on diaphragm rivet and internal support ring are adjacent to.Described clutch cover and described diaphragm rivet interlacement place are provided with the circular groove of indent.
Described diaphragm comprises diaphragm spring main body, and separation finger uniform in diaphragm spring main body inner ring, and described separation finger center is radially respectively arranged with stiffening rib protruding upward.Preferably, described stiffening rib is long strip groove, and long strip two is arc transition.Preferably, described stiffening rib is stamping forming boss stiffening rib.
Based on technique scheme, the invention has the beneficial effects as follows: the structure of the diaphragm rivet that the present invention adopts several circumferences uniform, simplify assembling work, when the raw fracture of internal support environment-development need be changed, diaphragm rivet can be pulled down very soon, then internal support ring is pulled down and change, and in the process changing internal support ring, to clutch cover not damaged.The stiffening rib that spring diaphragm is arranged, can overcome the shortcoming that clutch assembly backlash is large, improves vapour fatigue life of car clutch assembly, reduces the Separating force of clutch assembly simultaneously, simplify operating mechanism, saved cost.

Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As Fig. 1, shown in Fig. 2, a kind of diaphragm type spring clutch, comprise platen 11, clutch cover 12, diaphragm 13, internal support ring 14 and external support ring 15, also comprise the diaphragm rivet 16 that several circumferences are uniform, the left end of described diaphragm rivet 16 is provided with shoulder 161, the right side of described shoulder 161 is provided with crown towards pointed protruding 162 of the right side, described pointed projection is provided with concave arc surface 163, described diaphragm rivet 16 is successively from left to right by described internal support ring 14, described diaphragm 13, described external support ring 15 and described clutch cover 12 link together, and the described concave arc surface 163 on described diaphragm rivet 16 is adjacent to described internal support ring 14, to guarantee when fracture occurs internal support ring 14, internal support ring 14 can not come off from diaphragm-type automobile clutch, the safety and reliability of diaphragm-type automobile clutch can be improved.
Preferably, the radius of the described concave arc surface 163 on described diaphragm rivet 16, slightly larger than the steel wire radius of described internal support ring 14, when the steel wire diameter of internal support ring 14 has error, still can ensure that the concave arc surface 163 on diaphragm rivet 16 is adjacent to internal support ring 14.Described clutch cover 12 and the joint of described diaphragm rivet 16 are provided with the circular groove of indent.
As shown in Figure 3, Figure 4, described diaphragm 13 comprises diaphragm spring main body 131, and separation finger 132 uniform in diaphragm spring main body 131 inner ring, and described separation finger 132 center is radially respectively arranged with stiffening rib 133 protruding upward.Preferably, described stiffening rib 133 is long strip groove, and long strip two is arc transition.Preferably, described stiffening rib 133 is stamping forming boss stiffening ribs.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
