  • Patent number: 9598835
    Abstract: A continuously variable transmission includes a variator unit having a variator input shaft and a variator output shaft; a first planetary gear set having a first, a second and a third planetary member, the first planetary member being one of a ring wheel and a planet carrier, the second planetary member being the other one of the ring wheel and the planet carrier, and the third planetary member being a sun wheel, wherein the first planetary member of the first planetary gear set is operatively connected to a transmission input shaft; and a second planetary gear set having a sun wheel, a ring wheel and a planet carrier, the planet carrier being operatively connected to a transmission output shaft; wherein the variator input shaft is operatively connected to the second planetary member of the first planetary gear set; the variator output shaft is operatively connected to the sun wheel of the first planetary gear set, the sun wheel of the first planetary gear set being further operatively connected to the sun w

  • Patent number: 9068637
    Abstract: A powershift transmission in a motor vehicle is arranged between a prime mover and driven wheels of the motor vehicle for transmission of propulsive power and selection of different gear speed ratios. The powershift transmission includes at least two factional clutches for alternatively engaging at least two input shafts, a main transmission, a range section and an output shaft. A countershaft in the powershift transmission is rotationally connectable to the output shaft in order to establish a by-pass torque path, passing by the range section, and in which propulsive power can be transferred when the range section is gear shifted between different range speed ratios.

  • Publication number: 20150020624
    Abstract: A multi-clutch transmission is provided with a first and a second input frictional clutch, an input arrangement for establishing a driving connection of a prime mover and the first and second frictional clutches, and a main transmission. The main transmission has a first and a second rotational axis about which a main shaft and a countershaft is arranged respectively, an output shall and connection means for establishing a driving connection between the main shaft and the output shaft, and least two input shafts, which are connected to the first and second input frictional clutch, and a reverse shaft provided with a first reverse gear wheel. A reverse gear is achieved by transferring power over the reverse shaft to the output shaft.
