  • Shifting device and transmission unit
    Patent number: 9163702
    Abstract: A shifting device for a transmission unit, in particular for a vehicle which is operated by muscle force is disclosed. The shifting device has a first partial transmission and a second partial transmission, which are connected in series for power transmission. The selecting devices of the first partial transmission are designed as selectable free-running clutches and the second partial transmission has a plurality of selectable gear stages. During shifting from a highest stage of the gear stages of the first partial transmission to a lowest stage of the gear stages of the first partial transmission, the free-running clutches of the two gear stages are actuated simultaneously, and a load change between the corresponding free-running clutches allows a shifting operation of the second partial transmission to a higher stage of the gear stages.

  • Wave gear device
    Patent number: 9140350
    Abstract: The interior space of a cup-shaped flexible externally toothed gear of a cup-type wave gear device is divided into a front interior space and a rear interior space by a partition mechanism. A lubricant is filled in the front interior space at the side of a wave generator, to which lubrication is required. The volume of the front interior space is set so that a necessary amount of lubricant is filled. Since the lubricant is not necessary to fill in the entire interior space of the flexible externally toothed gear, the amount of lubricant to be filled can be reduced.
