Patent ID: 10513176

Abstract:
A vehicle transfer structure includes a main-drive-wheel output shaft that receives torque from a drive source and outputs it to main drive wheels, a part-time-drive-wheel output shaft provided parallel to the main-drive-wheel output shaft, a coupling provided on the main-drive-wheel output shaft and which partially extracts the torque to the part-time-drive-wheel output shaft via a transmission mechanism, and a damper disposed on the main-drive-wheel output shaft. The coupling is provided with an input-side coupling part coupled to an inner circumferential part of the damper. The input-side coupling part is coupled, via a spline-fitted section, to an output-side coupling part of a drive force transmission member which is coupled to an outer circumferential part of the damper and transmits a drive force to a driving-side transmission member of the transmission mechanism. The spline-fitted section allows a relative rotation between the input- and output-side coupling parts within a given angle.
