  • Patent number: 10823261
    Abstract: There is provided an automatic transmission capable of preventing deterioration of driving performance even when an engagement mechanism is not switched due to a failure. An automatic transmission includes a first brake which is always in a fixed state from a first forward gear stage to a predetermined gear stage and is in an open state at a gear stage with a higher speed than the predetermined gear stage, and a hydraulic sensor configured to detect whether the first brake is switched to the fixed state. When a transmission control device instructs the first brake to switch to the fixed state, and it is confirmed that the first brake is in an open state, the transmission control device instructs engagement mechanisms other than the first brake to perform switching so that a preliminary gear stage is able to be set.

  • Patent number: 9255627
    Abstract: An automatic transmission includes a thrust bearing ? disposed between a third sun gear of a third planetary gear mechanism and a second sun gear of a second planetary gear mechanism. Accordingly, transmitting a thrust load acting on the second sun gear of the second planetary gear mechanism from the thrust bearing to an input shaft via the third sun gear of the third planetary gear mechanism can avoid, as much as possible, a case where the thrust load is transmitted from the third planetary gear mechanism to the input shaft via a fourth planetary gear mechanism, and reduce friction loss of multiple thrust bearings interposed among elements or the like of the third planetary gear mechanism and the fourth planetary gear mechanism.

  • Patent number: 9140334
    Abstract: In an automatic transmission, a connection member which connects a carrier of a planetary gear mechanism PGSa to a clutch hub of a clutch is made to abut on the carrier of the planetary gear mechanism PGSa in an abutting portion, a thrust bearing T2 is disposed between the connection member and a clutch drum of the clutch, a thrust bearing T1 is disposed between a transmission case and the clutch drum of the clutch, and a clearance between the thrust bearing T1 and the clutch drum of the clutch is adjusted by using a shim. Accordingly, a thrust load inputted from a sun gear Sb of a planetary gear mechanism PGSb can be transmitted to the transmission case without passing through a sun gear Sa, which rotates at a high speed, of the planetary gear mechanism PGSa, and friction loss is reduced.

  • Patent number: 9140358
    Abstract: An automatic transmission includes an input member, a planetary gear set, a plurality of engagement mechanisms, an output member, a shift position detecting unit, an input rotational speed detecting unit, a control unit, and a switching mechanism. When a shift position is changed from a forward drive range to a reverse drive range, the control unit performs a reverse preparation mode in which a rotational speed of an element to be fixed by the switching mechanism is lower than or equal to a predetermined speed by setting an engagement mechanism in one of a connection mode and a fixed mode. Upon performing the reverse preparation mode, the control unit engages the engagement mechanism that connects the element fixed by the switching mechanism to the input member and, thereafter, engages the engagement mechanism that makes the rotational speed of the input member lower than or equal to the predetermined speed.
