摘要： PROBLEM TO BE SOLVED: To provide a torque converter lock-up clutch device for preventing vibration due to stick slip.
SOLUTION: A torque converter to which the lock-up clutch device is attached has a friction material adhered to one of a front cover and a lock-up clutch piston which gets into contact with each other. A connector to an engine is welded to the front cover, and a protruded portion is formed on the friction face by the welding distortion. As a result, even when the friction material is adhered to one of the front cover and the clutch piston, if relative rotating slip occurs therebetween, positive pressure and negative pressure are generated before and behind the protruded portion to cause stick slip. So, a groove 71 longer than the range of a welded porion 61 of the connector 6 is formed in the friction face of the friction material 7 to balance the fluctuation of pressure.

摘要翻译：要解决的问题：提供一种用于防止由于滑动导致的振动的变矩器锁止离合器装置。解决方案：安装有锁止离合器装置的变矩器具有粘附到彼此接触的前盖和锁止离合器活塞中的一个的摩擦材料。发动机的连接器焊接到前盖，并且通过焊接变形在摩擦面上形成突出部分。结果，即使当摩擦材料粘附到前盖和离合器活塞之一时，如果在其间发生相对旋转滑动，则在突出部分之前和之后产生正压力和负压，从而导致滑动。因此，在摩擦材料7的摩擦面上形成比连接器6的焊接部61的范围更长的槽71，以平衡压力的波动。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a lock-up clutch device capable of preventing the generation of grabbing chatter by stick slip without cutting an outer peripheral side-surface of a frictional material, in a lock-up clutch device used in a torque convertor.
SOLUTION: The drawing is a front view of a clutch piston 5 observed from a side where the frictional material 7 is stuck, the frictional material 7 is composed of an outer peripheral-side frictional material 71 and an inner peripheral-side frictional material 72, and 73 indicates a joint. A ratio of diatomaceous earth of a filler in the outer peripheral-side frictional material is more than that at the inner peripheral side, and μ-ν characteristic of the frictional material has positive gradient, thus the generation of grabbing chatter by stick slip can be prevented. Further as a coefficient of static friction is increased by adjusting components of the filler including a friction adjusting agent in the inner peripheral-side frictional material, a clutch can be more firmly engaged.

摘要： PROBLEM TO BE SOLVED: To provide a wet multiple disc friction plate providing compatibility between drag reduction during idling, and maintenance of a stable friction characteristic during meshing. SOLUTION: Spline fitting of spline teeth 42 of a friction plate 4 core plate 41 is carried out with a spline part 82 of an opposing hub 8. Segmented friction material 7 is adhered to the core plate 41, and a circumferential gap between segments forms an oil passage 75 in a radial direction. In the segment 7AC, a portion 70 wherein a height becomes gradually higher from an inner circumference part to an outer circumference part is formed from a radial center part to an inner diameter side of the friction material 7. The segment 7AD is not machined in such a way. An opening of an oil feeding hole 81 of the hub can be formed as a pair with the segment 7AC machined as above. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To obtain a wet friction material having a large shear strength, a long peeling life, high heat resistance, large durability and good initial compatibility. SOLUTION: This wet friction material comprises a fiber base material, a filler, a friction-controlling material and a thermosetting synthetic resin. Therein, the wet friction material is obtained by mixing the fiber base material with a paper-makable solid thermosetting resin as a part of the filler, processing the mixture into paper, impregnating the paper with a liquid thermosetting resin and subsequently thermally setting the resin. The solid thermosetting resin is preferably phenolic resin. The solid thermosetting resin is further a silicone resin preferably having an average composition formula: (R1 )a (OR )b SiO(4-a-b)/2 , and the amount of a trifunctional unit (RSiO3/2 ) monomer (R is a substituted or non-substituted monovalent hydrocarbon group) constituting the silicone resin is 40-100 mol.%.
