摘要： PURPOSE:To obtain a lubricating device simple in assembling and rigid at its connecting part by connecting the carrier of a simple planetary gear set to a second intermediate shaft and press feeding lubricating oil, fed by centrifugal oil pressure from a constantly-rotated first intermediate shaft, into the carrier from the oil hole of the second intermediate shaft. CONSTITUTION:The rear end of a second intermediate shaft 620 is provided with the sun gear 131 of a third simple planetary gear set 130 as well as spline- engaged with the carrier 123 of a second simple planetary gear set 120 through a connecting part 123a. The sectional form of the connecting part 123a is tapered in such a way as to make its inner diameter part axially longer, thus extending its engaging length with a spline 621 so as to improve the rigidity of the connecting part. As a first intermediate shaft 610 is constantly rotated, centrifugal oil pressure is generated to the lubricating oil in an oil passage 614 and an oil hole 614b, so that the lubricating oil can be press-fed into the oil passage 123b of the carrier 123 by this centrifugal oil pressure through the oil hole 620a of the second intermediate shaft 620.

摘要： PURPOSE:To improve the lubrication of planetary gear mechanisms by forming the first oil chamber between outside rotary shafts within multiple rotary shafts, communicating it to the second oil chamber formed on the innermost rotary shaft, and connecting the first oil chamber to a transmission case lubricating oil passage. CONSTITUTION:The second and the fourth planetary gear mechanisms 22 and 24 require lubrication at the first, second and fifth speeds when relative rotation is generated. The fourth rotary shaft 204 is kept stationary at the second and fifth speeds, and the lubricating oil fed to an oil chamber 116 from an oil chamber 117 in the first rotary shaft 201 via an oil passage 131 is forcefully fed via oil passages 114 and 115 of a center support 113. On the other hand, the lubricating oil fed to the oil chamber 116 enters an outside space 120 by the rotary centrifugal force of the fourth rotary shaft 204 at the first speed, the feed to the oil passage 115 is stopped, and lubricating oil is fed to the fourth clutch 34 via an oil passage 132 by that quantity. Lubricating oil is fed to the first one-way clutch 41 via an oil passage 121 and to the bearing 111 and thrust washer 112 of the planetary gear mechanisms 22 and 24 via oil passages 122 and 123. satisfactory lubrication is performed accordingly.

摘要： PURPOSE:To miniaturize the captioned device by providing a first bridge having holes for making planetary pinions pass through and second and third bridges for pivotally supporting the planetary pinions, on a carrier for rotatably supporting two planetary pinions. CONSTITUTION:In planetary gear mechanisms 22, 24 which commonly use planetary pinions 224 and a ring gear, the planetary pinions 224 are rotatably supported by a carrier 223. The carrier 223 consists of a first bridge 223a having a plurality of holes 225 through which the planetary pinions 224 pass and openings 226 formed between each of the holes and second and third bridges 223b, 223c which extend to both sides thereof to rotatably support the planetary pinions 224. The leg portions of the second and third bridges 223b, 223c are inserted into the plurality of openings 226 in a radially laminated condition and are fixed by means of welding. Hence, by increasing the number of the planetary pinions 224 to reduce load distribution, the length of sun gears 221, 241 can be made smaller. Thus, the captioned device can be miniaturized as a whole.

摘要： PURPOSE:To make the captioned gear compact by slidably fitting a piston for engaging/disengaging a backing speed change controlling clutch in a piston for engaging/disengaging a forwarding speed change controlling clutch. CONSTITUTION:A piston 331 for engaging/disengaging a backing speed change controlling clutch 33 for transmitting a driving force to a fourth planetary gear mechanism 24 at the time of backing, is slidably fitted in a piston 321 for engaging/disengaging a forwarding speed change controlling clutch 32 for transmitting a driving force to a second planetary gear mechanism 22 in at least a defined speed change stage at the time of forwarding. Thereby, the axial length can be made smaller as compared to the case where both pistons 321, 331 are simply arranged in the axial direction while also reducing the radial dimension as compared to the case where they are simply superposingly arranged in the radial direction. Thus, a planetary gear speed change mechanism 20 as a whole can be made compact.

摘要： PURPOSE:To prevent the interference of a lock up mechanism in a lock up piston and a turbine runner by forming a first driven plate to pinch to hold a first and a second cushioning members with expansion parts formed respectively and expanded to one side. CONSTITUTION:Since a drive plate 16 and a second driven plate 20 are pinched to be held by a pair of disc 17, 18 of a first drive plate 18, only the looseness of the inner peripheral end of the plate 19 and the plate 20 is a trouble about the vibration of the plate 18 in axial direction. But, since the plate 19 is supported by a peripheral wall 20e of an expansion part 20b with a flange part 18g of the inner peripheral end of the disc 18, the centering of the plate 19 is surely performed to support the plate 19 stably. Consequently, the looseness of the inner peripheral end of the plate 19 and the plate 20 is reduced to reduce the vibration of the plate 19 in axial direction. The plate 19 and the first and the second cushioning members 22, 23 hardly interfere in a lock up piston 14 or a turbine runner 6.
