| 摘要 |
A device for changing the mode of a power-branching transmission, that includes a casing to be connected to the transmission, an epicyclic train with three inputs, a mechanism blocking a first input relative to the casing that can be selectively actuated to establish a first operation mode of the transmission, and a kinematic chain provided with a connection mechanism connecting the first input with a second input, when the connection mechanism is actuated, to establish a second operation mode of transmission. The kinematic chain includes at least one meshing between two gears.
