摘要： An endless belt 1 for transmission is provided with a number of blocks 2, 3 which frictionally engage input and output pulleys, and vibration-absorbing members 6, 7 are interposed between mutually adjacent ones of the blocks 2, 3. The vibration-absorbing members 6, 7 are constituted by a first retainer 6 which clamps one block 2 of the mutually adjacent blocks 2, 3, and a second retainer 7 which clamps the other block 3, these retainers being intervening between the mutually adjacent blocks 2, 3. Accordingly, neighboring blocks 2, 3 are reliably prevented by the vibration-absorbing members 6, 7 from directly colliding with each other, as a result of which noise can be effectively reduced. In addition, vibration produced by the block 2 itself is absorbed by the first retainer 6 constituting the vibration-absorbing member. Likewise, vibration produced by the other block 3 itself is absorbed by the second retainer 7.

摘要： This invention relates to a belt driven continuously variable transmission having a pressure regulating cam mechanism giving a pulley an axial force which corresponds to transmission torque and eliminates torque transmission by friction between a pressure regulating cam and a fixed race. The stationary sheave, whose outer surface is supported, with rotation free at a case, by a bearing and whose inner side encloses the pressure regulating cam mechanism, has a circular hub elongating axially to the back side of the stationary sheave. Therefore, torque from the engine is transmitted to the fixed race of the regulating cam mechanism through an input member, and further transmitted to the stationary sheave through a roller and a movable race of the regulating cam mechanism. Consequently, the stationary sheave is supported at the case by the bearing and the radial load does not work on the pressure regulating cam mechanism. Therefore, the axial force generated by the pressure regulating cam mechanism can be set to correspond to the torque from the engine side without getting any influence from the torque transmission by friction.

摘要： A belt driven continuously variable transmission unit which converts the rotation of the input member by continuously variable ratios, and a gear unit such as a planetary gear unit to which the output torque from said continuously variable transmission unit and torque from said input member transmitted through a transfer unit is fed and delivered to the output member, are provided. A clutch and arresting member, such as a brake and one-way clutch are provided on the input path to said gear unit from said transfer unit. When the arresting member is actuated to low speed mode, the gear unit functions as a reduction mechanism, whereas when the arresting member is engaged to high speed mode, the gear unit functions as a split-drive mechanism which combines the output torque from said continuously variable transmission unit with the torque transmitted through said transfer unit. Formation of torque loop is prevented while combining the torques, by driving the element of the gear unit which supports reaction when the gear unit is functioning as a reduction mechanism.
