TORQUE CONVERTER CONNECTING DEVICE PROVIDED WITH VIBRATION DAMPER

摘要

PROBLEM TO BE SOLVED: To dismount a torque converter connecting device formed between a torque converter and a crank shaft through a twist vibration damper by forming a connecting part arranged between the torque converter and the twist vibration damper as a joint for a shaft and a hub, which is provided with a vertical direction tooth shaped part. SOLUTION: A twist vibration damper 14 is installed on an end part of a crank shaft 1 by a bolt 15. The twist vibration damper is formed as a hub 6 provided with a tooth in a vertical direction on a connecting part due to connect it to a fluid dynamic torque converter 5. The hub 6 is fitted to a driving flange 2 of the fluid dynamic torque converter 5, which is formed as a shaft 7 provided with a tooth (a serration) in a vertical direction. The driving flange 2 is fixed and connected to a casing 4 of the torque converter 5 by a welding joint 3. A centering pin 9 is installed rotary-symmetrically with a rotary axis 8 on the driving flange 2.
