    摘要: An automatic transmission has a reduced axial dimension and includes a mission case portion providing a mounting surface for a valve body. Forces generated by a hydraulic servo in operation of a brake are confined to the inside of a rear cover joined to the mission case. An extension protrudes from the rear cover and extends into the interior of the mission case with a multi-plate brake splined thereto. The force generated in operation of the brake is received by the cylinder as a reaction force. However, since the hydraulic servo cylinder and the extension are both integral with the rear case, the reaction force is confined to the interior of the rear cover without acting on the mission case.

    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 spiral 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: Smooth driving of a vehicle is achieved by eliminating busy shift by providing a small gear ratio step between the two highest gear ranges while maintaining structural compactness of the transmission. In the second highest gear range or state, a first pinion P1 has a diameter smaller than that of a second pinion P2, both pinions P1 and P2 being coupled integrally and at least partially determining the second highest gear ratio. The gear ratio .lambda..sub.2 in the second highest gear range is described as 1+(Z.sub.S2 /Z.sub.R1).times.(Z.sub.P1 /Z.sub.P2). Since (Z.sub.P1 /Z.sub.P2) is always equal to 1.0 or less, the gear ratio can be made smaller without enlarging the diameter of the ring gear R1 significantly to decrease the gear ratio step to the highest gear range.

    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: 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.

    摘要: The invention eliminates the 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. An automatic transmission is such that 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. 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: 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.
