Title:
VEHICULAR AUXILIARY DRIVE DEVICE IMPROVED IN ROLLER DURABILITY
Document Type and Number:
Japanese Patent JP2018040326
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicular auxiliary drive device which avoids deterioration due to the friction heat of a roller and is improved in durability.SOLUTION: A vehicular auxiliary drive device includes: an engine roller integrally rotating with a crank shaft of an engine; a motor generator roller integrally rotating with a rotary shaft of a motor generator; a rotary roller integrally rotating with a rotary shaft of an auxiliary machine driven by the engine or the motor generator; a first idler roller whose outer peripheral surface is energized in a direction contacting with outer peripheral surfaces of the motor generator roller and the engine roller; a second idler roller whose outer peripheral surface is energized in a direction contacting on the outer peripheral surfaces of the engine roller and the rotary roller; and a third idler roller whose outer peripheral surface is energized in a direction contacting with outer peripheral surfaces of the rotary roller and the motor generator roller. The outer peripheral surface of the motor generator roller is formed by a material having hardness or an elastic coefficient larger than either of the first idler roller or the third idler roller.SELECTED DRAWING: Figure 2
