摘要： A hydraulic actuator has a hub, an annular recessed groove on the inner peripheral surface of the hub and an oil chamber, from which a slanted oil channel is pierced to the bottom of the recessed groove. Accordingly, there is no need for the slanted oil channel to extend to the inner peripheral surface of the hub, by which the slanted oil channel can save its length. The oil is sent from the supply oil channel formed in the boss section to the annular recessed groove of the hub in slidable contact with the boss section, and to the oil chamber through the slanted oil channel.

摘要： A carrier is provided with a flange-shaped carrier cover directly secured to a pinion shaft which supports a pinion, and the carrier cover is integrally formed to a countershaft by heat forging. The carrier cover is formed with a lubricant oil hole extending from the countershaft toward the pinion shaft, and the countershaft is formed with a small diameter on the side bounded by the carrier cover where the planetary gear unit is positioned, and with a large diameter on the opposite side. As a result, the countershaft has a high degree of strength and forms a compact gear unit in the axial direction. Lubricant is supplied from a lubricant oil hole in the center of the shaft to a lubricant oil hole formed in the carrier cover, and is forcedly fed to the support surface of the pinion through oil holes in the pinion shaft. The axial force from the counterdriven gear is applied to a thrust bearing between the hub and the carrier cover, and the axial force is backed up by the large diameter section of the shaft.

摘要： A thrust washer has a protrusion which is formed with a projecting pawl. The rotating member is formed with a through hole, into which the protrusion of the thrust washer is inserted, such that the pawl is projected out on the opposed surface remote from the thrust washer of the rotating member, whereby the upstanding surface of the pawl is used as a stop means. Thus, the thrust washer is positively secured to the rotating member.

A stator shaft, which bears the stator reaction of a torque converter, is engagingly secured in a center hole section of an oil pump assembly, an annular flange section projecting to the radially outer side is formed at one end of the stator shaft, the snap ring groove is defined from the annular flange section and an annular recessed section of the oil pump assembly to receive the snap ring, and a receiving member for the return spring of the hydraulic actuator is maintained by the snap ring installed in the snap ring groove. Consequently, the return spring, which applies the return force to the piston of the hydraulic actuator, has its reaction force borne at the annular flange section of the stator shaft through the receiving member and the snap ring.

摘要： A stator shaft is press-fitted and secured to the inner peripheral surface of a pump cover positioned between a torque converter and a automatic transmission mechanism section. Bushings are fitted to a part opposing the press-fit section with reference to the outer peripheral surface of an input shaft fabricated with a uniform diameter with the exception of the rear end part, and to a part slightly forward of the above-mentioned part, respectively, and an oil channel for the torque converter feed pressure is formed between the two bushings. As a result, the forward end section of the input shaft is supported in a freely rotatable manner by the bushings which are relatively close to each other. The torque converter feed pressure is fed from an oil channel formed in the pump cover to an oil channel between the two bushings, and through the cross hole and the center hole formed in the input shaft to the torque converter. The stator shaft is press-fitted into the pump cover and secured to it, and back-up is provided to the press-fit section by bushings.

摘要： A ring gear and an outer race of a one-way clutch are linked and secured in the axial direction. The outer peripheral section of a disk-shaped supporting member engages teeth of the ring gear and supports the ring gear, and a tapered snap ring is mounted in an indented groove with a tapered surface formed in the ring gear so that the side surface of the outer peripheral section of the support member is in intimate contact with the end surface of the outer race, and the support member is thus secured and prevented from withdrawing. An oil sump for lubricant supplied from the inner radial side is formed on the inner peripheral part of the outer race defined by the intimately contacted outer race and the support member. The ring gear of the planetary gear unit rotates when the automatic transmission actuates, and the integral support member also rotates based on the rotation of the ring gear. At this time, the side surface of the outer peripheral section of the support member is in intimate contact with the end surface of the outer race because of the tapered snap ring, and the lubricant supplied from the inner radial side is stored in the inner radial part of the outer race, which becomes the oil sump to lubricate the one-way clutch.

摘要： In a dual planetary gear of an automatic transmission, tooth surface pressure generated at a relatively short pinion is decreased and distributed since the pinion is formed as a pair of pinions. These pinions can be pinions which mesh with a sun gear or pinions which mesh with a ring gear and a single first pinion. Torque exerted on the ring gear (or the sun gear) is transmitted to the sun gear (or the ring gear) through one point of contact (or two) between the sun gear and one pinion (or a pair of pinions) and the ring gear and two points of contact (or one) between a pair of pinions (or one pinion) and the ring gear.

摘要： A compact automatic transmission for a vehicle capable of preventing increase in relative rotational speed between shift elements. A planetary gear unit is provided with a sun gear to which rotation of an input shaft is input, a carrier that can be stopped from rotating, and a ring gear for outputting, to a planetary gear set, rotation that is reduced in speed relative to that of the input shaft. A clutch is connected/disconnected, the input shaft and the sun gear are appropriately connected/disconnected, and the carrier is appropriately stopped/unstopped by a brake and a one-way clutch. This prevents relative rotational speed between shift elements of the gear unit that does not participate in a shifting operation from excessively increasing. When the clutch is disposed between the input shaft and the sun gear, the torque capacity of the clutch can be reduced as compared with the case where it is disposed between the gear unit and the gear set. Therefore, the clutch can be formed into a more compact structure and the overall automatic transmission can be made more compact.
