Title:
BELT-TYPE TRANSMISSION MECHANISM FOR AUXILIARY MACHINE AND ITS CONTROL METHOD
Document Type and Number:
Japanese Patent JP2019032043
Kind Code:
A
Abstract:
To provide a belt-type transmission mechanism for an auxiliary machine which can secure optimum belt tension when operating the auxiliary machine by controlling belt tension according to an operation state at the auxiliary machine side, can reduce a loss caused by friction by lowering the belt tension when torque transmission not operating the auxiliary machine is unnecessary, and can improve fuel economy, and its control method.SOLUTION: In a belt-type transmission mechanism having a drive-side pulley at a crankshaft side of an internal combustion engine, a receiving-side pulley at an auxiliary machine side, a transmission belt, a hydraulic tensioner for generating belt tension so as to avoid a slide of the transmission belt, and a tension control device for controlling the hydraulic tensioner, the tension control device controls the hydraulic tensioner according to an operation state of an auxiliary machine.SELECTED DRAWING: Figure 1
