Power take-off apparatus in automotive vehicle

摘要

A power take-off apparatus in an automotive vehicle equipped with an automatic power transmission including a rotary element arranged to be driven by a prime mover of the vehicle when the transmission is conditioned in a neutral position during stopping of the vehicle and to be arrested when the power transmission is conditioned in a forward position. The power take-off apparatus comprises a drive gear mounted on the rotary element for rotation therewith, a driven gear arranged to be meshed with the drive gear, an electrically operated shift mechanism including an electric motor, and a linkage connected to the motor to move the driven gear toward and away from the drive gear in response to energization of the motor, and an electric control circuit for effecting energization of the motor when the transmission is maintained in the forward position during stopping of the vehicle and for maintaining the motor in its deenergized condition when the transmission is shifted to the neutral position. The linkage of the shift mechanism is provided with resilient means for biasing the driven gear toward the drive gear when the former is engaged with an end face of the latter.
