Transmission with integrated PTO input gear damper

摘要

A power take-off unit (“PTO”) may include a damper to reduce noise while the PTO is operating at low torque or at low RPM. The damper may also be located in the transmission before the PTO driver gear. A method may be used to systematically measure the frequency and/or amplitude of the vibrations that cause noise and to adjust the damping constant of a damper to reduce the noise.
