Accessory drive device in engine
A device is described which drives accessories such as an alternator, a cooling water pump, an air-conditioning compressor or the like, utilizing power taken from an output shaft of an engine, the device comprising: an input shaft rotatably supported on a stationary plate and receiving output from the output shaft and rotated at a rotational speed corresponding to that of the output shaft; a transmission output member rotatably supported on the input shaft for transmitting the power to the accessories; a planetary cone which can rotate on the input shaft in revolution around the axis of the input shaft and in self-rotation about an axis inclined with respect to the axis of the input shaft; an input transmission member installed rotatable with the input shaft and engaged at its outer periphery in frictional engagement with the second frictional transmission surface of the planetary cone; a transmission ratio varying member for varying the position of the shifting ring in direction toward or away from the rotation center of the planetary cone using the rotational speed of the transmission output member as a parameter and suppressing the rise of the rotational speed of the transmission output member when the rotational speed of the transmission output member because larger than a prescribed value; the transmission output member having two end plate members positioned on both ends thereof; the end plate members together with the input shaft constituting an enclosed annular infusion chamber filled with an amount of frictional transmission oil; and a pressure adjusting device for adjusting the pressure of the frictional transmission oil in the infusion chamber.
