The method produces a friction plate having oil grooves communicating between the internal periphery and the external periphery, by fixing friction material segments formed from a friction material to a core plate, and is featured by forming the oil grooves by plastic working of the friction material and fixation of the friction material segments with predetermined gaps therebetween to the core plate.
Description
- 1. Field of the Invention
- The present invention relates to a method for producing a friction plate adapted for use in an automatic transmission or a lock-up clutch of vehicles such as automobiles and an apparatus therefor.
- 2. Related Background Art
- In the prior art, plural segments of friction material are adhered to a core plate with a predetermined gap between the segments, thereby forming oil grooves for lubricating oil on the friction plate.
-
FIG. 8 shows an example of such conventional method for producing a friction plate. Segments of the friction material are prepared for example by punching from atape 5 of the friction material. Thesegments 3 of the friction material are fixed on a core plate 1 with gaps 4 in the circumferential direction to form afriction plate 10, and such gaps 4 constitute oil grooves. - The above-described conventional method for forming the friction plate has been associated with the following drawbacks:
-
- 1) As the plural segments of the friction material are extracted from the friction material tape and are adhered with predetermined gaps to the core plate, there are required time and work for forming the oil grooves of the required number; and
- 2) Also as it is necessary to obtain the friction material segments of a relatively large number from the tape, the throughput of the material such as the tape of the friction material is undesirably low, resulting in a significant waste of the material.
- In consideration of the foregoing, an object of the present invention is to provide a method for producing the friction plate capable of improving the throughput of the friction material and reducing the time required for adhering the segments of the friction material to the core plate.
- For attaining the above-mentioned object, the present invention is firstly featured by a method for producing a friction plate formed by fixing friction material segments, formed from a friction material, to a core plate and having oil grooves communicating between the internal periphery and the external periphery of the segments:
-
- wherein the oil grooves are formed by plastic working of the friction material and fixation of the friction material segments with a predetermined gap therebetween to the core plate.
- Also the present invention is secondly featured by a method for producing a friction plate formed by fixing friction material segments, formed from a friction material, to a core plate and having oil grooves communicating between the internal periphery and the external periphery of the segments:
-
- wherein the oil grooves are formed by cutting of the friction material and fixation of the friction material segments with a predetermined gap therebetween to the core plate.
- Also the present invention is thirdly featured by an apparatus for producing a friction plate formed by fixing friction material segments, formed from a friction material, to a core plate and having oil grooves communicating between the internal periphery and the external periphery of the segments, comprising:
-
- means for punching a band-shaped friction material to obtain plural friction material segments;
- means for holding the friction material segments by stacking on a metal mold or a jig and pushing out the friction material segments in succession to a side opposite to the metal mold; and
- means for pressing and adhering the friction material segments to the core plate;
- wherein the oil grooves are formed by plastic working of the friction material and fixation of the friction material segments with a predetermined gap therebetween to the core plate.
- Also the present invention is fourthly featured by an apparatus for producing a friction plate formed by fixing friction material segments, formed from a friction material, to a core plate and having oil grooves communicating between the internal periphery and the external periphery of the segments, comprising:
-
- means for punching a band-shaped friction material to obtain plural friction material segments;
- means for holding the friction material segments by stacking on a metal mold or a jig and pushing out the friction material segments in succession to a side opposite to the metal mold; and
- means for pressing and adhering the friction material segment to the core plate;
- wherein the oil grooves are formed by cutting of the friction material and fixation of the friction material segments with a predetermined gap therebetween to the core plate.
- Also the present invention is fifthly featured by a friction plate formed by fixing friction material segments, formed from a friction material, to a core plate and having oil grooves communicating between the internal periphery and the external periphery of the segments:
-
- wherein the oil grooves are formed by plastic working of the friction material and fixation of the friction material segments with a predetermined gap therebetween to the core plate.
- Also the present invention is sixthly featured by a friction plate formed by fixing friction material segments, formed from a friction material, to a core plate and having oil grooves communicating between the internal periphery and the external periphery of the segments:
-
- wherein the oil grooves are formed by cutting of the friction material and fixation of the friction material segments with a predetermined gap therebetween to the core plate.
- Also the present invention is seventhly featured by a friction plate formed by fixing friction material segments, formed from a friction material, to a core plate and having oil grooves communicating between the internal periphery and the external periphery of the segments:
-
- wherein the friction material segments are fixed with a predetermined gap therebetween to the core plate and then subjected to cutting for forming the oil grooves.
- The time required for adhering work can be reduced since the friction material segments of a number fewer than in the prior art are adhered to the core plate. Also the throughput of the material can be improved.

FIG. 8 is a plan view of the friction plate, showing a conventional method for producing the same. - Now the present invention will be explained in detail by preferred embodiments thereof, with reference to the attached drawings, wherein corresponding components are represented by corresponding numbers.
-
FIG. 1 shows a first embodiment of the present invention and is a plan view showing the mode of punching plural friction material segments from a tape of the friction material and adhering the segments to an annular core plate. The band-shaped friction material, or thefriction material tape 16, has predetermined thickness and width. Pluralfriction material segments 11 of a same shape are obtained for example by press punching of thefriction material tape 16. - The
friction material segment 11 has an arc shape, having a predetermined radial width and a predetermined circumferential width. Thefriction material segment 11 is composed of anexternal periphery portion 11 a of a curvature same as that of theannular core plate 12, aninternal periphery portion 11 b, andcircumferential edge portions 11 c for connecting theexternal periphery portion 11 a and theinternal periphery portion 11 b at both ends thereof in the circumferential direction. - The
friction material segments 11 are adhered and fixed, for example with an adhesive material, to both top and rear faces of thecore plate 12 or a face thereof. In the first embodiment shown inFIG. 1 , fourfriction material segments 11 are fixed circumferentially to thecore plate 12. At the adhesion, a predetermined gap is formed between theedges 11 c of thefriction material segments 11 to formoil grooves 14 for the lubricating oil in the automatic transmission. - As the width of the
friction material segments 11 in the radial direction thereof is smaller than that of thecore plate 11 in the radial direction thereof, a substantiallyannular groove 15 is formed on thecore plate 12 after the adhesion of thefriction material segments 11. Thisannular groove 15 communicates with theoil grooves 14. In case thefriction material segments 11 are adhered on both faces of thecore plate 12,respective grooves 15 are naturally formed on both faces thereof. As shown inFIG. 1 , thefriction material tape 16 is provided in advance with agroove 13 by plastic working such as pressing or roller pressing or by cutting. Consequently, thegroove 13 is formed in thefriction material segment 11 at the preparation thereof for example by punching from thefriction material tape 16. Thegroove 13 is provided at the approximate center of thefriction material segment 11, penetrating through the segment in the radial direction. Consequently, after the adhesion of thefriction material segments 11 on thecore plate 12, theoil grooves 14 and thesecond oil grooves 13 are positioned radially, with a substantially constant pitch. Thegrooves 13 also communicate with theannular groove 15, thus communicating also with theoil grooves 14. - In the present embodiment, four
friction material segments 11 are adhered to thecore plate 12, but such number is not limited to four and may be selected otherwise. Also thegroove 13 provided in thefriction material tape 16 need not be limited to one but can also be provided in plural units. - The
friction plate 20 formed by fixing thefriction material segments 11 to thecore plate 12 is lubricated with lubricating oil in the actual use, and the presence of thegroove 15 communicating with theoil grooves 14 and thegrooves 13 achieves smooth flow of the lubricating oil, thereby improving the lubricating ability. In particular, there is ensured smooth flow of the lubricating oil in the radial direction from the external periphery side to the internal periphery side of thefriction plate 20 and in the opposite direction from the internal periphery side to the external periphery side. -
FIG. 2 shows a second embodiment of the present invention and is a plan view showing the mode of punching plural friction material segments from the friction material tape and adhering the segments to the core plate. As the basic configuration is similar to that in the first embodiment, there will be explained the different points only. - The
friction material segments 11 are adhered and fixed, for example with an adhesive material, to both top and rear faces of thecore plate 12 or a face thereof. In the second embodiment, agroove 17 in thefriction material segment 11 is not provided in advance on thefriction material tape 16 but is formed by plastic working such as pressing at the punching of thefriction material segment 11 from thefriction material tape 16. - Consequently, after the adhesion of the
friction material segments 11 on thecore plate 12, theoil grooves 14 and thesecond oil grooves 17 are positioned radially, at a substantially constant pitch. Thegrooves 17 also communicate with theannular groove 15, thus communicating also with theoil grooves 14. - In the present embodiment, four
friction material segments 11 are adhered to thecore plate 12, but such number is not limited to four and may be selected otherwise. Also thegroove 17 formed simultaneously with the punching need not be limited to one but can also be formed in plural units. - The
friction plate 60 formed by fixing thefriction material segments 11 to thecore plate 12 is lubricated with lubricating oil in the actual use, and the presence of thegroove 15 communicating with theoil grooves 14 and thegrooves 17 achieves smooth flow of the lubricating oil, thereby improving the lubricating ability. In particular, there is ensured smooth flow of the lubricating oil in the radial direction from the external periphery side to the internal periphery side of thefriction plate 60 and in the opposite direction from the internal periphery side to the external periphery side. -
FIGS. 3 and 4 show a third embodiment of the present invention.FIG. 3 is a plan view showing the mode of punching plural friction material segments from the friction material tape and adhering the segments to the core plate.FIG. 4 is a plan view of the completedfriction plate 70. As the basic configuration is similar to that in the first embodiment, there will be explained the different points only. - The
friction material segments 11 are adhered and fixed, for example with an adhesive material, to both top and rear faces of thecore plate 12 or a face thereof. In the third embodiment, agroove 18 in thefriction material segment 11 is not provided in advance on thefriction material tape 16 nor formed at the punching of thefriction material segment 11 for example by pressing from thefriction material tape 16, but is formed by pressing, roller pressing or cutting after thefriction material segment 11 is adhered to thecore plate 12, namely at the final adhesion. - Consequently, after the adhesion of the
friction material segments 11 on thecore plate 12, theoil grooves 14 and thesecond oil grooves 18 are positioned radially, at a substantially constant pitch. Thegrooves 18 also communicate with theannular groove 15, thus communicating also with theoil grooves 14. - In the present embodiment, four
friction material segments 11 are adhered to thecore plate 12, but such number is not limited to four and may be selected otherwise. Also thegroove 18 formed at the final adhesion need not be limited to one but can also be formed in plural units. - The
friction plate 70 formed by fixing thefriction material segments 11 to thecore plate 12 is lubricated with lubricating oil in the actual use, and the presence of thegroove 15 communicating with theoil grooves 14 and thegrooves 18 achieves smooth flow of the lubricating oil, thereby improving the lubricating ability. In particular, there is ensured smooth flow of the lubricating oil in the radial direction from the external periphery side to the internal periphery side of thefriction plate 70 and in the opposite direction from the internal periphery side to the external periphery side. -
FIGS. 5 and 6 are elevation views of the friction material segment, showing examples of the arrangement of grooves in case of forming plural grooves on thefriction material segment 11 for example by pressing. InFIG. 5 ,grooves 19 are formed on thefriction material segment 11 in radial manner with a constant pitch in the circumferential direction. On the other hand, inFIG. 6 ,grooves 29 are formed in parallel manner. This configuration, allowing formation of plural grooves in a step, is suitable for example for roller pressing or cutting. - In
FIGS. 5 and 6 , three grooves are formed in afriction material segment 11, but another number may naturally be selected. -
FIG. 7 is a schematic view showing the entire configuration of anapparatus 30 for executing the methods for producing the friction plate of the foregoing embodiments. Thecore plate 12 is supplied from a coreplate entry unit 31 of a transporting (transfer) line 53, and the suppliedcore plate 12 is transported in a direction X. - The
core plate 12 is then subjected to the coating of the adhesive material on the lower face, by a firstadhesive coating device 34 in afirst coating unit 33 for coating the adhesive. The core plate, with the adhesive material coated on the lower face, is subjected, in a frictionmaterial adhesion unit 35, to the adhesion, on the lower face, of the friction material segments supplied from a first frictionmaterial supply device 44 through a lowerface adhesion station 36. - Subsequently, the
core plate 12 is subjected to the coating of the adhesive material on the upper face, by a secondadhesive coating device 38 in asecond coating unit 37 for coating the adhesive. Thecore plate 12, with the adhesive material coated on the upper face, is subjected, in a frictionmaterial adhesion unit 39, to the adhesion, on the upper face, of the friction material segments supplied from a second frictionmaterial supply device 45 through an upperface adhesion station 40. There are also shownfriction material tapes 50 supplied from the friction material supply-devices - The
core plate 12, bearing the adhered friction material segments on the upper and lower faces, is transported to adischarge unit 41, then transported to anentry unit 42 for a post process, and is subjected to the simultaneous application of heat and pressure for 15 to 30 seconds for achieving final adhesion in a post process (final adhesion)unit 43 to provide the completedfriction plate 55. - In
FIG. 7 , thegroove 13 of the first embodiment is formed in a step A, while thegroove 17 of the second embodiment is formed in a step B, and thegroove 18 of the third embodiment is formed in a step D. In a step C, the groove is formed on the friction material segment after the adhesion thereof but prior to the final adhesion, or after the final adhesion. - As explained in the foregoing, the present invention provides the advantages of:
-
- improving the throughput of the friction material; and
- reducing the time and process for fixing the friction material segments to the core plate.
