    摘要: A variable transmission includes various powerpath layouts consisting in either; a single mode with approximately symmetrical reverse and forward speeds and includes an input shaft, one or two planetary gear sets, or a planetary gear set and a compound gear set when the RTS (ring-to-sun) ratio of the planetary gear set is not physically possible; or a dual mode with each mode being selected by closing a clutch/brake and releasing the other. A first up-speed planetary gear set on the input side of a variator, and a second planetary gear set on the output side of the variator, both configured to split the torque when drivingly engaged with a variator comprising, a first ring assembly, and a second ring assembly. Various up-speed ratio arrangements are shown that tend to increase the speeds and decrease the torque acting on the CVP, allowing a decrease in the variator size.

    摘要: A torque ripple compensating device for an internal combustion engine is provided. The torque ripple compensating device comprises a first member, a second member, and a third member. The first member is in driving engagement with an output of the internal combustion engine. The second member is in driving engagement with the first member. The third member is in driving engagement with the second member. An angular deviation between the first member and the third member causes a cyclical acceleration of the third member. The cyclical acceleration of the third member applies a torque to the output of the internal combustion engine through the first member. The torque ripple compensating device is able to be passively or dynamically adapted for both an amplitude and a phase of a torque ripple while minimizing an interference with an operation of the internal combustion engine.
