TIMING CHAIN FRICTION REDUCTION DEVICE FOR A VEHICLE CAPABLE OF REDUCING FRICTION LOSS OF THE CONTACT SURFACE OF A TENSIONER ARM AND CHAIN A GUIDER

摘要

PURPOSE: A timing chain friction reduction device for a vehicle is provided to increase the thickness of an oil film by respectively forming a fraction reducing unit to a tensioner arm and a chain guider.;CONSTITUTION: A crank sprocket(3) transfers torque of a crank shaft to a cam shaft. A timing chain(7) interconnects the crank sprocket and a cam sprocket. The cam sprocket is mounted to the cam shaft. A tensioner arm(9) and a chain guider are respectively formed on both sides of the timing chain in order to reducing vibration of the riming chain and prevent secession of the riming chain. The tensioner arm controls tension of the timing chain by being arranged at the left side of the timing chain. The chain guider guides the timing chain by being arranged at the right side of the timing chain.;COPYRIGHT KIPO 2012
