Automated manual transmission

摘要

An automated manual transmission includes an input, an output disposed in parallel with the input, a common use planetary gear device disposed on the input or the output, a shift gear device in which a plurality of external gear mates having different shift ratios are disposed on the input and the output, and a friction member disposed to transmit the rotation power transmitted to the input at the time of the braking to the output through the external gear mates.

1. An automated manual transmission, comprising:
an input configured to rotate by being supplied with a rotation power from an engine; an output disposed in parallel with the input; and a shift gear device including:
a common use planetary gear device disposed on the input and provided with three rotation elements, a first rotation element of the three rotation elements being connected to the input; and a plurality of pairs of external gears having different shift ratios and each pair of the external gears including a first gear disposed on the input and a second gear disposed on the output in a meshed state with the first gear at all times,
wherein at least two pairs of the plurality of the pairs of the external gears include first input external gears rotatably disposed on the input and connected to a second rotation element of the common use planetary gear device to share the second rotation element of the common use planetary gear device; anda first friction member disposed to brake a third rotation element of the common use planetary gear device to make the common use planetary gear device transmit the rotation power from the input to the output through one of the plurality of the pairs of the external gears.
