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 shift control apparatus has first, second, third and fourth engagement elements, and a shift control processing unit engaging the first and the second engagement elements in order to realize a first shift speed, engaging the third and the fourth engagement in order to realize a second shift speed, and inhibiting an increase in torque capacity of one of the first and second engagement elements before starting of release of the second engagement element when shifting from the first to the second shift speed. During shifting from the first to the second shift speed, an increase in torque capacity of one of the first and second engagement elements is inhibited before starting of release of the second engagement element. This prevents a step-like shift shock from being caused by the slowed progression of shifting when release of the second engagement element is started.

摘要： The invention has been made to eliminate a feeling of two-phase speed-change operations by causing a speed-change operation to proceed continuously when the speed-change operation is performed through two-phase control of engagement and release of four engagement elements. To accomplish this purpose, the invention provides a control apparatus for an automatic transmission wherein a predetermined speed-change operation is achieved through a pre-phase speed-change operation in which a first engagement element and a third engagement element are released and engaged respectively and through a post-phase speed-change operation in which a second engagement element and a fourth engagement element are released and engaged respectively. The control apparatus sets a target rotational acceleration of an input shaft of the transmission, and controls release of the second engagement element for a transition to the post-phase speed-change operation in accordance with the target rotational acceleration. Thus, the input speed during the transition from the pre-phase speed-change operation to the post-phase speed-change operation changes continuously, so that bluntness is prevented from being caused between the pre-stage and post-stage speed-change operations.

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 speed-reducing gear unit is provided for causing a reduced-speed rotation output member to have a reduced rotation that is slower than rotation of an input shaft. The reduced-speed rotation output member is switched between a reduced-speed rotation state and a free rotation state by rotation state switching means. The reduced-speed rotation of the reduced-speed rotation output member is selectively transferred to fourth and first elements of a speed-changing dual planetary gear unit via first and third control clutches. The rotation of the input shaft is transferred to a second element via a second control clutch. Rotations of the first and second elements are selectively restricted by first and second control brakes. A third element is connected to an output shaft. This makes it possible to provide a high-efficiency automatic transmission that achieves seven or more forward gear ratios so as to allow optimal extraction of engine performance in a high vehicle speed region and reduce the vehicle speed change at the time of a gear shift and therefore provide a good feeling, by adding gear speeds including a locked-up speed at a high gear speed side so that adjacent gear ratios are closer to each other.

A control apparatus has a torque control capability for adjusting an input torque of a transmission during the pre-phase speed-change control, and ensures continuous changes in the input speed during the pre-phase and post-phase speed-change operations through adjustment of the input torque (torque reduction) to prevent bluntness from being caused between the pre-phase and post-phase speed-change operations.

摘要： A shift control apparatus that advances activation of an engagement element to be engaged during a shift requiring engagement and release of four engagement elements, thereby reducing the shift time. The automatic transmission achieves a sixth-to-fourth-to-third shift by controlling servo pressures for the four engagement elements. The control apparatus starts, during the time of the sixth-to-third shift, supply of the hydraulic pressure for activating the engagement element to be engaged at the time of the fourth-to-third shift, thereby advancing the establishment of the engagement stand-by state at the time of the fourth-to-third shift. Accordingly, the reduction in the servo pressure of the engagement element to be released at the time of the fourth-to-third shift can be advanced, thereby reducing the time for the sixth-to-third shift.

摘要： An automatic transmission achieves a desired shift through an initial stage shift in which a first engagement element is released and a third engagement element is engaged, and a final stage shift in which a second engagement element is released and a fourth engagement element is engaged. A control apparatus sets an estimated rotation acceleration for a transmission input shaft in accordance with an input torque and an input torque rotation acceleration speed, and controls the release of the second engagement element for moving to the final stage shift according to the estimated rotation acceleration. As a result, it is possible to prevent a shifting delay and/or degradation that occurs between the initial stage and the latter stage by continuous transmission of the input rotation (engine rotation) change when moving from the initial stage to the later stage.
