摘要： In a breather device linking a space within a transmission case (1) to outside air, a breather (10) is provided at a middle position in a lengthwise direction on an upper portion of the transmission case, in particular, at a position displaced in an axial direction from a middle position in the lengthwise direction, and opens to outside air via a ventilating mechanism (2) that extends in a direction opposite this displaced direction. Thus, through the combination of displacement in a lengthwise direction of the position of the breather with respect to a middle portion in a lengthwise direction of the transmission case and the direction of the ventilating mechanism facing in a direction opposite that direction, the occurrence of breather blow is prevented during both forward and rearward axis tilting of the transmission by an action where a forward side of the ventilating mechanism lowers when,the position of the breather tilts in a direction away from the oil level, and conversely, where the forward side of the ventilating mechanism rises when the position of the breather tilts in a direction towards the oil level.

摘要： A transmission has an oil drain passage for connecting an oil reservoir with a mission case in a pump casing. The automatic transmission has also a retainer serving as a shielding member to shield between a discharge opening of the oil drain passage from at least part of a multistage transmission mechanism. This ensures that breather oil blow, which is caused by the spattering and stirring of operating oil by the high-speed drum member, is shielded from at least part of the transmission mechanism.

摘要： A transmission case is provided with a housing enclosing a clutch and/or torque converter connected to an engine, and a shifting mechanism case enclosing a shifting mechanism in an oil-tight state that is connected to the housing. A focus for stress resulting from an impact load acting on the transmission case is formed as a frangible portion in the housing. Thus, damage to the transmission from an excessive load is limited to the housing, and by absorbing the impact from that damage, damage to the shifting mechanism case is prevented and oil leakage from the transmission case is avoided.

摘要： A bottom portion of an intake port is provided with a sloped bottom surface formed of a plane such that sloped bottom surface approaches the side surfaces of external teeth and internal teeth from an upstream side to a downstream side in rotational direction of two rotors. Fluid that flows in the intake port is regulated by the sloped bottom surface and smoothly guided into individual inter-teeth chambers that are expanding. Since the sloped bottom surface on the bottom portion of the intake port is formed of a plane without spiral or twisting, design and manufacturing of a gear pump is extremely easy.

摘要： The level of quietness for an automatic transmission case is ensured by preventing vibration by improving the rigidity while suppressing the increase in the mass of a transmission case. In an automatic transmission case in which a valve body is attached to a case wall that covers the transmission mechanism, the rigidity of the automatic transmission case is increased by providing, in the case, an enclosing wall that projects out from the case wall and encloses the periphery of the valve body.

摘要： A multi-stage automatic transmission using a reduction planetary gear and a planetary gear set in which the respective thrust forces generated thereat are supported by a low bearing load or a low case load. The automatic transmission is provided with a reduction planetary gear, coupled to an input shaft to fix a reaction force element so as to output a reduction rotation to an output element, and a planetary gear set, that outputs a speed shift rotation upon input of the subsequent reduction rotation. During at least first gear driving, there is provided a force transmission route in which thrust forces generated at one element of the reduction planetary gear and one element of the planetary gear set, respectively, are transmitted. In that route, a torsion direction of the helical teeth of the respective elements are set such that a direction of a thrust force of the element and a direction of the thrust force of the other element are different from each other during first gear driving.

摘要： A multi-speed automatic transmission improves transmission efficiency by reducing drag loss due to high speed rotation of a freely rotating element of a planetary gear set. An automatic transmission for a vehicle includes: an input path T1 of a first speed ratio; an input path T2 which has a larger speed ratio than this input path T1; a planetary gear set of four elements, wherein the four elements are a first element, a second element, a third element, and a fourth element following an order of elements on a speed diagram; a clutch C-2 transmitting a rotation of the input path T2 to the first element S3; a clutch C-1 transmitting the rotation from the input path T2 to the fourth element S2; a clutch C-4 transmitting a rotation from the input path T1 to the first element; a clutch C-3 transmitting the rotation from the input path T1 to the second element C3; a brake B-1 engaging the fourth element; a brake B-2 engaging the second element; and an output member coupled with the third element R3. Accordingly, drag resistance is prevented from increasing because no extremely high speed rotation of the freely rotating element is generated, even when a speed is achieved using any combination of the engagement elements.

摘要： A vehicular automatic transmission, for establishing a plurality of forward gear stages, includes: a transmission case; an input shaft; a transmission mechanism connected to the input shaft and including a plurality of transmission elements; an output shaft connected to the transmission mechanism; a clutch drivably connecting any one of the input shaft and the transmission elements individually; and a hydraulic servo for applying the clutch responsive to an oil pressure. The transmission case encloses the transmission mechanism, the clutch and the hydraulic servo, and includes axial end walls, on one of which is formed a stationary cylinder for the hydraulic servo. A piston is slidably mounted in the cylinder and together with the cylinder, defines an oil chamber for receipt of the actuating oil pressure. A bearing is arranged between the piston and the clutch for transmitting the thrust force from the piston to the clutch, while allowing relative rotation between the piston and the clutch. The clutch includes a hub with an outer cylindrical surface splined to a friction plate assembly and a rim radially spaced from the hub with the friction plate assembly splined to its inner cylindrical surface. The input shaft is connected to the hub whereas one of the transmission elements is connected to the rim.

摘要： An automatic transmission for five forward speeds equipped with a main transmission mechanism and an auxiliary transmission mechanism. The auxiliary transmission mechanism includes a multi-disc clutch and a hydraulic servo therefor arranged in a first planetary gear set. The first planetary gear set includes a first ring gear connected to an output unit of the main transmission mechanism and a first carrier connected to an output shaft and further to a first sun gear through a multi-disc clutch and a hydraulic servo for the former. The hydraulic servo for the multi-disc clutch is connected to an integral casing through a band brake and is arranged around the outer circumference of the hydraulic servo for the multi-disc clutch. A second planetary gear set is arranged on the hydraulic servo for the multi-disc clutch and includes a second ring gear connected to the output shaft, a second carrier connected to the integral casing through a multi-disc brake and a second sun gear connected to the first sun gear through the cylinder of a hydraulic servo for the multi-disc clutch. The rear casing forms part of the cylinder of the hydraulic servo for the multi-disc brake. The auxiliary transmission mechanism has a compact three-speed construction to provide five forward speeds in cooperation with the main transmission mechanism. The five-speed automatic transmission can be easily modified merely by removing the second planetary gear set and the brake for the 1st speed to provide a four-speed transmission at a reasonable cost due to the sharing of parts in common.
