| 摘要 |
<p>The invention relates to a device for changing the mode of a power-branching transmission, that comprises a casing (24) to be connected to the transmission, an epicyclic train (G3) with three inputs (P3, PS3, C3), means (5) for blocking a first input (PS3) relative to the casing (24) that can be selectively actuated in order to establish a first operation mode of the transmission, and a kinematic chain provided with a connection means (20) for connecting the first input (PS3) with a second input (C3), when the connection means (20) is actuated, in order to establish a second operation mode of the transmission. The kinematic chain includes at least one meshing between two gears (16-21).</p> |
