Infinite speed ratio transmission device and assembly method thereof

摘要

An upper link (100) connecting four trunnions (30) of a first toroidal unit (2A) and second toroidal unit (2B) is formed of a first part (102) corresponding to the first toroidal unit (2A) and a second part (101) corresponding to the second toroidal unit (2B). The first part (102) is supported in a casing (14) via a first upper link supporting member (27X), while the second part (101) is fixed to the casing (14) via a second upper link supporting member (27Y). The first part (102) is also fixed to the second part (101) by bolts 105). The rotation outputs of the first toroidal unit (2A) and second toroidal unit (2B) are transmitted to a planetary gear unit (5) via a chain (40) from an output sprocket (24) provided between the two toroidal units (2A, 2B).
