The elastic height control structure comprises an upper friction plate, a lower friction plate, a first cushioning plate, a second cushioning plate, a first rivet and a second rivet, wherein the first cushioning plate comprises a first heaving part and a first extending part; the second cushioning plate comprises a second heaving part and a second extending part; the first cushioning plate and the second cushioning plate are arranged in the opposite directions; the first heaving part faces the second extending part, and the second heaving part faces the first extending part; the first rivet penetrates in the first heaving part and the second extending part, and the first heaving part and the second extending part are fixed on the inner side of the upper friction plate through the first rivet; and the second rivet penetrates in the second heaving part and the first extending part, and the second heaving part and the first extending part are fixed on the inner side of the lower friction plate. According to matching of the two cushioning plates and the rivets, elasticity errors of the cushioning plates are eliminated through autofrettage pressure of the rivets and the cushioning plates, and the heights of the friction plates of a clutch driven plate assembly are well controlled.
Description
Technical field
The utility model relates to a kind of clutch driven disc assembly friction plate, and relating in particular to is a kind of clutch driven plate elasticity height control structure.
Background technique
The corrugated sheet of conventional clutch clutch drived disk assy is monolithic structure, and friction plate is connected to one by rivet and corrugated sheet.The friction plate height of clutch driven plate directly determines by corrugated sheet, and because corrugated sheet adopts highly resilient material, molding resilience is large, and raw-material difference in thickness is large simultaneously, and high consistency is poor.The high consistency of the friction plate of clutch driven plate is poor, and the most direct result causing is exactly the poor stability at clutch pedal bonding point.
In addition, consider from the monophasic waveform sheet mechanism of action, stressed less in the time starting to be out of shape of monophasic waveform sheet, then, along with the increase of distortion, the increase of power is very fast, until be driven plain.As shown in Figure 1, for monophasic waveform spring sheet, its anti-bullet go down performance be easier to decay, its attenuation process can follow its waveform amount to reduce gradually, even become the spring sheet without waveform amount, therefore the now binding ability of driven disc and gearing meeting reduce gradually or lost efficacy, and the smooth-going performance of combination of clutch drived disk assy can not embody.
At present, two corrugated sheet are also to have use, as Chinese patent " clutch driven plate (patent No.: 201210556061.7) " with double wave shape spring sheet discloses a kind of clutch driven plate with double wave shape spring sheet, as shown in Figure 2: between driven disc two friction plates, be provided with the double wave shape spring plate group being formed by two wavy spring sheets, symmetrically, the height of each spring sheet is the half (i.e. the half of two friction plate height) of original spring sheet waveform height, waveform height consistent with existing monophasic waveform spring sheet height (i.e. two friction plate height) after spring sheet combination, and realize fixing by three rivets, wavy spring sheet and two friction plates are fixed by rivet, and fix by rivet between spring sheet.But friction plate height is still subject to the impact of corrugated sheet distortion, is directly determined by two corrugated sheet, causes the poor problem of high consistency.
Model utility content
The purpose of this utility model is to provide a kind of clutch driven plate elasticity height control structure of corrugated sheet elasticity to friction plate effect of altitude of avoiding.
For solving the problems of the technologies described above, the utility model clutch driven plate elasticity height control structure, comprising: upper friction plate and lower friction plate; The first corrugated sheet, described the first corrugated sheet comprises the first ridge and the first extension part; And second corrugated sheet, described the second corrugated sheet comprises the second ridge and the second extension part; Wherein said the first corrugated sheet and described the second corrugated sheet arrange in opposite directions, and described the first ridge is towards described the second extension part, and described the second ridge is towards described the first extension part; The first rivet, described the first rivet is arranged in described the first ridge and described the second extension part, and described the first ridge and described the second extension part are fixed on described upper friction plate inner side by described the first rivet; The second rivet, described the second rivet is arranged in described the second ridge and described the first extension part, and described the second ridge and described the first extension part are fixed on described lower friction plate inner side by described the second rivet.
Preferably, the height of described the first ridge and described the second ridge is the half of spacing between described upper friction plate and described lower friction plate.
The utility model clutch driven plate elasticity height control structure, by the cooperation of two corrugated sheet and rivet, utilizes the preload pressure of rivet and corrugated sheet to eliminate the flexible error of corrugated sheet, has controlled well the height of clutch driven disc assembly friction plate.
In addition, by rivet, corrugated sheet height restriction is arrived to original half, realize corrugated sheet height consistent, avoid being subject to the impact of corrugated sheet distortion, therefore they have less amount of plastic deformation and the stronger elastoresistance performance that goes down, after two corrugated sheet Symmetric Composites, the non-deformability of corrugated sheet group can strengthen greatly, can the long period under average service conditions keep original waveform amount and shape, thus can gentle start can guarantee vehicle starting time, smooth-going while simultaneously ensureing gearshift.

Embodiment
Below in conjunction with accompanying drawing, the utility model clutch driven plate elasticity height control structure is described in further detail.
As Fig. 3 shows, the utility model clutch driven plate elasticity height control structure, comprise: upper friction plate 1 and lower friction plate 2, the first corrugated sheet and the second corrugated sheet arrange in opposite directions, the first ridge 3 of the first corrugated sheet is towards the second ridge 5 of the second extension part 6, the second corrugated sheet towards the first extension part 4; The first rivet 7 is arranged in the first ridge 3 and the second extension part 6, is fixed on upper friction plate 1 inner side, and the second rivet 8 is arranged in the second ridge 5 and the first extension part 4, is fixed on lower friction plate 2 inner sides.The height of the first 3 of protuberances and the second ridge 5 is half of spacing between upper friction plate 1 and lower friction plate 2 simultaneously.
The utility model clutch driven plate elasticity height control structure, by the cooperation of two corrugated sheet and rivet, utilizes the preload pressure of rivet and corrugated sheet to eliminate the flexible error of corrugated sheet, has controlled well the height of clutch driven disc assembly friction plate.
In addition, by rivet, corrugated sheet height restriction is arrived to original half, realize corrugated sheet height consistent, avoid being subject to the impact of corrugated sheet distortion, therefore they have less amount of plastic deformation and the stronger elastoresistance performance that goes down, after two corrugated sheet Symmetric Composites, the non-deformability of corrugated sheet group can strengthen greatly, can the long period under average service conditions keep original waveform amount and shape, thus can gentle start can guarantee vehicle starting time, smooth-going while simultaneously ensureing gearshift.
Below the preferred embodiment of the utility model having been created illustrates, but the utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all modification being equal to or replacement under the prerequisite without prejudice to the invention spirit, and the modification that these are equal to or replacement are all included in the application's claim limited range.
