  • Patent number: 11242923
    Abstract: A continuously variable transmission includes a case member including an outer surface on the side where a torque converter is disposed and an inner surface on the side where a driving force transmission mechanism is disposed. The case member includes a supporting hole by which a bearing that supports a third shaft is supported, a supporting hole by which a bearing that supports a fourth shaft is supported, and an oil path through which an lubricant, to be supplied to the bearing and the bearing, is supplied. The oil path protrudes from the outer surface from the case member and has a straight line shape connecting between the supporting hole and the supporting hole. Thus, components can be appropriately lubricated even when it is difficult to provide lubrication pipes.
    Type: Grant

  • Patent number: 10837541
    Abstract: Provided is a lubricant guiding structure in an automatic transmission in which a baffle plate configured to regulate the movement of a lubricant agitated by a driven sprocket is provided at one side, where an oil pump is located, in the direction of a rotational axis of the driven sprocket. As viewed from the rotational axis direction, a division wall disposed to extend across a chain is provided closer to the chain than a base of the baffle plate. As viewed from the rotational axis direction, the baffle plate is provided with a guide wall extending along a torque transmission-side chain of the chain wound on the driven sprocket. As viewed from the rotational axis-direction, the guide wall includes an inclined portion inclined in the direction coming closer to the chain as the distance to the distal end side decreases.
