  • Patent number: 9212736
    Abstract: A holding structure of an intervening member is provided for preventing the dropping-out of a wobbling-prevention member at an assembly time, and to extend an applicable range of rigidity of the intervening member to a low-side range. The holding structure of the intervening member includes a baffle plate intervened between a torque converter housing wall and an intervening member, and a wobbling-prevention member interposed between the baffle plate and the torque converter housing wall in a compressed state. A bottom portion of a concave portion is clamped between a head portion and a bulging portion of the wobbling-prevention member. Also, an inside of the head portion is hollow, so when the head portion is crushed and deformed, the air inside the head portion is discharged to the outside through an annular gap to reduce a compressive load relative to the baffle plate.

  • Patent number: 8413759
    Abstract: An oil-pressure output device (electric pump unit) is arranged on an outer wall face of an automatic transmission which is positioned on an opposite side to an engine (left side of a vehicle). An arrangement position of the oil-pressure output device is out of a movable range of one of the steered driving wheels which is located on the opposite side to the engine (left front wheel). Accordingly, a simpler layout change between a case of attaching the oil-pressure output device to the automatic transmission and another case of not attaching the one can be provided, so that commonality of components or layout of the automatic transmission and its surrounding devices and structures can be provided.

  • Patent number: 8197374
    Abstract: An automatic transmission comprises a multi-plate brake to brake a specified rotational element of a transmission mechanism, which includes a plurality of frictional plates, a piston, a piston cylinder member comprising cylinder in which the piston slides, and oil-pressure chambers which are formed between the piston and the cylinder and bias the piston toward the frictional plates with an oil pressure supplied thereto, and a valve body to supply the oil pressure to the oil-pressure chambers. Herein, the valve body is provided in the vicinity of an outer periphery of the piston cylinder member so as to be connected to the piston cylinder member via a connection portion, and there is provided an oil passage to supply the oil pressure from the valve body to the oil-pressure chambers via the connection portion.
