摘要： PROBLEM TO BE SOLVED: To surely provide a larger reduction effect in drag torque and to achieve further improvement in fuel consumption even when agitating torque increases because an oil sump section is formed in the outer periphery of a wet friction material in a torque transmitting mechanism for an automatic transmission. SOLUTION: In the torque transmitting mechanism 1 for the automatic transmission, a core plate 3 of a segment type friction material 2 is provided with an outer peripheral projection 6 in four positions of the periphery, and incorporated in a separator plate 7 with each other to the segment type friction material 2. The radius of the outer peripheral projection 6 of the core plate 3 is set smaller by 1.25 mm than the radius of an outer periphery of the portion where a projection 7A for spline engagement of the separator plate 7 is not provided, and the radius of the outer periphery of the other portion of the core plate 3 is set smaller by 1.75 mm, then a wide space is obtained between the outer periphery of the core plate 3 of the wet type friction material 2 and the outer periphery of the separator plate 7 so as to have sufficient space to let lubricating oil flow.

摘要： PROBLEM TO BE SOLVED: To provide a friction material capable of attaining excellent initial characteristics and a high positive μ-V gradient while keeping ultra-high heat resistance without undergoing strength decrease.
SOLUTION: Base fibers and a filler are made into a paper-like sheet (S10). The paper-like sheet is impregnated with a thermosetting resin (S11), and the impregnated sheet is dried in a fashion in which the temperature of a friction surface is lower, and the temperature of a surface opposite to the friction surface is higher (S12). Because the resin in the friction material moves from the lower temperature part to the higher temperature part as the result of pull by the solvent which moves to the higher temperature part and becomes dry, the distribution of resin quantities in the thickness direction can be highest near the surface opposite to the friction material and can be lowest near the friction surface. The thermosetting resin is heat-cured (S13), and, of the part made entirely of the resin on the friction surface, an about 10±5 μm ultrasurface part is removed by grind with an abrasive (S14). The thus obtained friction material 1 can attain an excellent positive μ-V gradient because of the reduced influence of the resin as well as the low resin concentration near the surface of the friction surface.

摘要翻译：要解决的问题：提供能够获得优异的初始特性和高的μ-V梯度的摩擦材料，同时保持超高的耐热性而不会降低强度。解决方案：将基底纤维和填料制成纸状片（S10）。纸状片材用热固性树脂浸渍（S11），并且以摩擦面的温度较低的方式干燥浸渍的片材，并且与摩擦面相反的表面的温度较高（S12 ）。由于摩擦材料中的树脂由于通过移动到较高温度部分并变干的溶剂的拉动而从较低温度部分移动到较高温度部分，所以树脂量在厚度方向上的分布可以在接近与摩擦材料相对的表面可以在摩擦表面附近最低。将热固性树脂热固化（S13），并且在摩擦表面上完全由树脂制成的部分通过用磨料研磨除去约10±5μm的超表面部分（S14）。这样得到的摩擦材料1由于树脂的影响减小以及摩擦面表面附近的低树脂浓度，可获得极好的μ-V梯度。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To effectively suppress the rise of the temperature of a wet friction material during the engagement, to prevent a friction material base on the surface of the wet friction material from being worn, and to extend the life of the wet friction material in a separator plate.
SOLUTION: In this separator plate 1, a plurality of grooves 2 (72 grooves for one surface) are radially formed in each surface of a steel plate of flat plate ring shape. The grooves 2 are formed in a generally V shape with a width (w) and a depth (d) in cross section. The grooves 2 are formed in the separator plate 1 over the entire surface. The width (w) of the grooves 2 is within the range of 50 to 500 μm, and the depth (d) is within the range of 10 to 500 μm. They have proper width and depth, therefore, as oil grooves for suppressing the rise of the temperature of the wet friction material to be contacted, can effectively suppresses the rise of the temperature during the engagement. Since the depth of the oil grooves is not too deep and the width is not too wide, a friction material base material on the surface of the wet friction material is not worn, and the life of the wet friction material is extended.

摘要翻译：要解决的问题：为了有效地抑制接合期间湿摩擦材料的温度升高，为了防止湿摩擦材料的表面上的摩擦材料基体被磨损，并延长其寿命隔板中的湿摩擦材料。解决方案：在该隔板1中，在平板环形钢板的每个表面中径向地形成有多个槽2（一个表面的72个槽）。槽2形成为宽度（w）和深度（d））的大致V形状。槽2在整个表面上形成在隔板1中。槽2的宽度（w）在50〜500μm的范围内，深度（d）在10〜500μm的范围内。它们具有适当的宽度和深度，因此，作为用于抑制要接触的湿摩擦材料的温度上升的油槽可以有效地抑制接合期间的温度上升。由于油槽的深度不太深，宽度不够宽，因此摩擦材料表面上的摩擦材料基材不会磨损，并且湿摩擦材料的寿命延长。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a larger effect of reducing drag torque in a wet friction material even at a part where the quantity of lubricating oil is large and at a part where lubricating oil is hard to flow through.
SOLUTION: In a wet friction material 1, when rotated in a direction of an arrow mark in a non-engaged state, an ATF (automatic transmission fluid) supplied from the inner periphery as shown by a branched arrow mark abuts on an enlarged portion 3d on the rotation rear side to supply the ATF to a friction surface of a friction material base material 3B, and the ATF further abuts on a slotted part 3a of a friction material base material 3A to supply the ATF to the outer peripheral side from an intermediate part of the friction surface of the friction material base material 3A. As a result, the ATF is positively supplied to the whole friction surfaces of the friction material base materials 3A, 3B to surely suppress contact between a separator plate and the friction surface, thereby obtaining a greater remarkable effect of reducing drag torque. When the segment type friction material 1 idles in a reverse direction, the enlarged portion of the friction material base material 3B and the slotted part 3b of the friction material base material 3B on the opposite side play the same role.

摘要： PROBLEM TO BE SOLVED: To certainly have a greater reduction effect in drag torque and to achieve further improvement in fuel consumption even when agitating torque increases because an oil sump section is formed in the outer periphery of a wet type friction material in a torque transmitting mechanism for an automatic transmission. SOLUTION: In the torque transmitting mechanism 21 for the automatic transmission, the radius of a portion 20 other than a plurality of spline grooves 18A in the inner periphery of the automatic transmission case 18 is set larger than the radius of the outer periphery of a core plate 23 of a segment type friction material 22 as a wet type friction material by 2.0 mm. A wide space is thereby obtained between the outer periphery of the core plate 23 of the wet type friction material 22 and the inner periphery 20 of the automatic transmission case 18, and a sufficient space exists to let lubricating oil flow along the outer periphery of the wet type friction material 22 so that the drag torque is certainly prevented from being increased because an oil sump section is formed in the outer periphery when the wet type friction material 22 runs idle in any direction in a non-fastened state.

摘要： PROBLEM TO BE SOLVED: To certainly have a greater reduction effect in drag torque and to achieve further improvement in fuel consumption even when agitating torque increases because an oil sump section is formed in the outer periphery of a wet type friction material in a torque transmitting mechanism for an automatic transmission. SOLUTION: In the torque transmitting mechanism 41 for the automatic transmission, the radius of a portion other than an outer peripheral projection 26 of the outer periphery of a separator plate 27 is set smaller by 1.45 mm than the radius of the inner periphery of an automatic transmission casing 8. The radius of the outer peripheral projection 26 is set slightly smaller by 0.2 mm than the radius of the inner periphery of the automatic transmission casing 8.

摘要： PROBLEM TO BE SOLVED: To provide a wet type friction material having reliably improved friction property by precisely forming grooves as oil grooves in the surface of a base material for the friction material similarly to the case of forming oil grooves with pressing work while reducing pressing steps.
SOLUTION: In a process of manufacturing the base material for the friction material where segment pieces 3 as part of the wet type friction material 1 are cut out, a step of forming paper making grooves in the surfaces with pressing or cutting work while making paper is first performed, whereby a groove depth can be precisely formed because a paper making body has no elasticity. The wet type friction material 1 has total eighty oil grooves consisting of twenty segment grooves 5 formed in spaces among twenty segment pieces 3 and three paper making grooves each in the surfaces of the twenty segment pieces 3. In this way, deep segment grooves 5 and shallow paper making grooves 4 are mixed to obtain improved friction property which a conventional segment wet type friction material cannot have.

摘要： PROBLEM TO BE SOLVED: To obtain an excellent dragging torque reduction effect even in relatively low revolution range by further promoting the discharge of an automatic transmission fluid (ATF) at disengagement time without changing specifications of separator plates of a counter member and an outer periphery drum that engages with the plates in a wet friction material.SOLUTION: A segment type friction material 1A as a wet friction material is structured by bonding a plurality of segment pieces 3 lined with spaces 5 and a pulling-in portion 6 using an adhesive (thermosetting resin) on a core metal 2A of steel plate of a flat ring shape with a plurality of oil grooves 4A passing through in the radial direction on both sides are provided and by bonding the same similarly on the back surface of the core metal 2A. A test result of the relationship of relative revolutions and the dragging torque demonstrates that the dragging torque reduction effect is larger over a wide range of relative revolutions (500 to 3,000 rpm) as compared with a segment type friction material (having no oil grooves on the core metal) related to a prior art.
