Title:
AUXILIARY DRIVING DEVICE OF ENGINE
Document Type and Number:
Japanese Patent JP2017166616
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an auxiliary driving device of an engine including a driven shaft to which driving force of a driving shaft is transmitted by an endless transmission member, which can prevent release of tension on a tension side of the endless transmission member due to angular velocity fluctuation of the driving shaft, and reduce average tension of the endless transmission member.SOLUTION: An auxiliary driving device of an engine 1 includes a driving shaft (crank shaft 21), a driven shaft (oil pump driving shaft 31), an endless transmission member (driving chain 33), a first tensioner (first hydraulic tensioner 41) disposed on a loose side of the endless transmission member, and a second tensioner (second hydraulic tensioner 43) disposed on a tension side of the endless transmission member. The second tensioner has an attenuation function of attenuating pressing force in a case of being pressed in an anti-energization direction from the endless transmission member.SELECTED DRAWING: Figure 2
