摘要： PROBLEM TO BE SOLVED: To obtain a wet type friction material which does not allow falling off of carbon particles during use and which can prevent change of frictional characteristics which is caused by such falling off of carbon particles. SOLUTION: The friction material has carbon particles added to the frictional sliding surface to improve heat resistance and durability but carbon particles are removed from the outermost surface part of brake lining 3 to form no carbon layer in the frictional surface 1 in order to prevent falling off of carbon particles during use. Layer 2 having a large amount of carbon particles is formed several filaments of the fiber below it (20-50 μm below the outermost surface). Composing a wet type brake lining in this manner can prevent the carbon particles from falling off and also prevent change of frictional characteristics which would be caused by such falling off of carbon particles.

摘要： PROBLEM TO BE SOLVED: To provide a friction engaging device with strong pressing force and less quantities of parts. SOLUTION: In the Figure, numeral 5 is a clutch drum having a spline groove 4 in an inside perimeter, numeral 6 is a pressing piston, numeral 7 is an oil hole, numeral 8 is a pressing plate, numerals 12, 13 are friction plates, numeral 14 is an end plate, numeral 15 is a stopper ring, numeral 55 is a clutch hub and numeral 56 is a spline groove, when the friction plates are pressed on, a power is transmitted between the clutch drum 5 and the clutch hub 55. In the friction engaging device, a lever member 20 of almost coned disc spring shape is installed between the pressing piston 6 and the pressing plate 8. Inducing hydraulic pressure from the oil hole 7 and pressing the pressing piston 6 leftwards make the lever member 20 be pressed at an power point Q, to rotate clockwise pivoting on a fulcrum P and press the pressing plate 8 at the action point F. Since a distance between P and Q is greater than a distance PF, a force pressing the action point P increases than a force pressing the power point Q. When the oil is extracted, the lever member 20 of cone disc spring shape is returned to its original form by its own restoring force, and engagement of the friction plates 12, 13 are relieved. Therefore a return spring can be omitted.

摘要： PROBLEM TO BE SOLVED: To improve production efficiency by forming the connecting part of a friction material and a core plate by a blanking process, etc., at the time of sticking the friction plate to the core plate or after sticking. SOLUTION: A large-diameter friction material 3 corresponding to a large core plate 1 and a small-diameter friction material 4 corresponding to a small core plate 2 are simultaneously blanked from a friction material tape or the like by a press process (A). Secondly, an adhesive for sticking a friction material is applied to the upper surface of the integrated large-core plate 1 and small- core plate 2, and further the large-diameter friction material 3 and the small- diameter friction material are placed thereon process (B). the core plate and the friction materials are placed on an adhering device and heat and pressure are simultaneously applied thereto. At the time of adhesion or after the completion of adhesion by heat and pressure, the respective connecting parts 5, 6 are all blanked by a punch process (C). Thus, a friction plate 10 having the large-diameter friction material 3 made adhere to the large core plate 1 and a friction plate 20 having the small-diameter friction material 4 made adhere to the small core plate 2 are separated to be formed as independent products.

摘要： PROBLEM TO BE SOLVED: To provide a lockup assembly with damper improved in the shearing force between a core plate and a retainer plate even with a small size. SOLUTION: The drawing is a front view of a lockup piston with damper consisting of a core plate 22 and a retainer plate 23, wherein the core plate 22 is fixed to the retainer plate 23 by a fastening part 26. A spring 32 is a damper spring held by the retainer plate 23. When the reduction in size and weight of the device is further promoted, the retainer plate 23 is also minimized to narrow the fastening range, so that the shearing force with the core plate 22 becomes insufficient. Therefore, a protruding part 40 laid along the circumferential edge is provided on both circumferential end outer sides of the retainer plate 23. The shearing force can be improved by this protruding part.

摘要： PURPOSE:To prevent air from being mixed into oil in advance even when an inferior position is generated in a jointed part. CONSTITUTION:A strainer body 4 consists of an upper plate 7, a lower plate 8, a net and so on. The upper side of the lower plate 8 is extended more upwards than a jointed part 11, and a covering part 12 which almost covers the upper plate 7 is formed integratedly. A space between the covering part 12 and the upper plate 7 is made an oil holding part 13 for storing and holding oil A. As a result, even if the jointed part 11 is exposed to the air and an inferior position is generated in the jointed part 11, only the outer surface of the lower plate 8 is exposed directly to the air, and oil A is held in the oil holding part 13. It is thus possible to prevent air from invading from the inferior position of the jointed part 1.

摘要： PROBLEM TO BE SOLVED: To effectively and efficiently reduce the NOx emission amount. SOLUTION: In an engine system 10, an ECU executes EGR control. In the processing, the ECU 100 acquires the influx exhaust gas temperature, the DPF upstream exhaust gas temperature, and DPF downstream exhaust gas temperature sensed by various sensors, the sucked air amount sensed by an air flow meter 218, the sucked air temperature sensed by a first sucked air temperature sensor 205, and the exhaust gas absolute pressure sensed by an absolute pressure sensor 232, and thereupon presumes the catalyst bed temperature Tdpf. Further, the ECU 100 presumes the PM deposited amount in the PDF 227 on the basis of the exhaust gas differential pressure sensed by a differential pressure sensor 233, and presumes the PM reproduction speed Rpm in the DPF 227 on the basis of the obtained PM deposited amount, the described sucked air amount, and catalyst bed temperature Tdpf. On the basis of Rpm presumed, the target EGR rate is set. COPYRIGHT: (C)2009,JPO&INPIT
