摘要： An input disc and/or an output disc of a variable-speed drive, as of the toroidal type, has a central boss portion for attachment to a shaft and a radially extending flange portion with an annular concave power-roller engaging surface. An opposite surface of the flange portion is an annular convex surface having a plurality of radial reinforcement ribs formed thereon. In one preferred form, the ribs have upper surfaces which are inclined so that the front edges thereof are lower than the rear edges thereof in a rotational direction of the disc.

摘要： An input shaft of a toroidal-type infinitely variable transmission is supported at opposite ends by respective bearings which are secured to a housing, and input and output disks and power rollers are mounted at an intermediate portion of the input shaft. The input shaft has a flange at one end which is connected to an engine, and a pressure adjusting Belleville washer is interposed between the inner end face of the flange and the outer end face of the bearing to bias the input shaft in the direction of the engine so that a predetermined pressing force is applied to the input and output disks and the power rollers during a period in which a small input torque is transmitted to the input shaft. As the input torque increases, the input shaft is moved axially together with a loading cam against the spring force of the Belleville washer, and the inner end face of the flange and the outer end face of the bearing directly abut each other so that a required reaction force is obtained. In this case, since a needle-shaped roller bearing is interposed between the inner peripheral surface of the bearing adjacent the flange and the outer peripheral surface of the inmput shaft, the sliding movement of the input shaft in the axial direction encounters a small frictional resistance.

摘要： A transmission control apparatus for an infinitely variable transmission in which a transmission operating amount is selected by a transmission operating amount selecting system from a memory stored table based on transmission control information from transmission control information detectors which detect the transmission control information such as a throttle opening position command signal, etc., and a driving motor which enables the transmission operation of the infinitely variable transmission to be controlled in an open-loop fashion by a transmission control system in accordance with the transmission operating amount. The transmission operating amount selected by the transmission operating amount selecting system is compared with a predetermined set value by a transmission operating amount decision system to decide whether or not the transmission operating amount is equal to or larger than the predetermined set value, and based on the decision result, the driving motor is driven to rotate by a driving speed selecting system such that, for example, at the time of usual transmission in which the operating amount is small, the driving motor is driven at a low speed, whereas at the time of rapid acceleration or kick down in which the operating amount is large, the driving motor is driven at a high speed.

摘要： A loading cam device is constructed of a first cam surface, a second cam surface, a ring-shaped retainer disposed between the first and second cam surfaces and defining pockets at angular intervals, and rolling members maintained in contact with the first and second cam surfaces while rotatably held within the respective pockets. The circumferential width of each pocket is smaller at each side of the retainer but greater along a thicknesswise central axis of the retainer, both compared with the outer diameter of the rolling members. As an alternative, the thickness of the retainer is a little smaller at a location adjacent to each pocket but significantly smaller at a location remote from the pocket, both compared with the thickness the outer diameter. As a further alternative, springs are disposed between surface portions of the retainer, said surface portions being on opposite sides of the retainer, respectively, and being located between each two adjacent pockets, and the first and second cam surfaces, whereby the springs resiliently urge the retainer in directions away from the first and second cam surfaces, respectively.

摘要： A frictional transmission comprises first and second rotary shafts arranged in directions in which the central axes thereof crossed each other, a roller supported coaxially with the first rotary shaft for rotating with the first rotary shaft, a first frictional surface provided on the roller coaxially with the first rotary shaft, a disc supported coaxially with the second rotary shaft for rotating with the second rotary shaft, and a second frictional surface provided on this disc coaxially with the second rotary shaft. The second frictional surface and the first frictional surface are brought into frictional engagement with each other. A loading cam device is arranged so as to press the second frictional surface toward the first frictional surface at the time of driving. A further disc coaxial with the aforementioned disc is disposed in the environs of the second rotary shaft, and the roller is sandwiched by and between the two discs. This further disc is rotatably supported by an angular-type ball bearing relative to the second rotary shaft and the first-mentioned disc in the environs of the second rotary shaft in a state that this further disc is prevented from being displaced in a direction to be separated from the first-mentioned disc.
