Dual clutch transmission

摘要

A dual clutch transmission for motor vehicles, with two subtransmissions, with a dual clutch, with a central disk (3) connected to the driving disk (2) and belonging to the dual clutch, with two outer pressure plates (4, 5) and with friction disks (6, 7) which are arranged between the central disk (3) and the pressure plates (4, 5) and which can be coupled individually to the central disk (3) and transfer the torque selectively to the sub transmissions via one of the clutch output shafts (solid shaft 10, hollow shaft 11). Dual clutch transmissions often suffer from noise and vibration problems which mostly arise during crawling actions, when starting from a standstill, in load alternation processes and during gear changes. In order to avoid this, the central disk (3) is decoupled from the driving disk (2) and is mounted on the hollow shaft (11); furthermore, the central disk (3) is connected cardanically to the driving disk (2).

主权项

1. A dual clutch for a transmission, comprising;
a driving disk; a central disk connected to the driving disk; first and second outer pressure plates; a first friction disk located between the central disk and the first pressure plate and a second friction disk located between the central disk and the second pressure plate, each configured to be coupled individually to the central disk and to transfer torque selectively to a respective one of first and second clutch output shafts; the central disk being resiliently decoupled from the driving disk and mounted on one of the clutch output shafts; and first, second and third damper stages, wherein the damper stages include an energy absorption system and an energy accumulator system for reducing amplitude of torsional non-uniformities input into the driving disk.
