Abstract

The invention provides a belt tension regulating device of an engine for improving workability in belt replacement, by detecting a reduction amount in belt tension, early and accurately determining a time for regulating the belt tension or a time for replacing belts, and detecting a change amount of the belt tension from above or in front of the engine without cutting of the view caused by an automatic tensioner and the belt. The belt tension regulating device of an engine comprises: an accessories driving pulley connected with a clank pulley through the belt 2; a tension pulley 5 wound in the middle of the belt; and the automatic tensioner 3 in which a moving end of an actuator is connected with the tension pulley through a connection arm to change a position of a rotation center of the tension pulley and thereby to change the belt tension. An indication member attached to an moving end of the actuator, and a detection member detecting the position of the indication member are provided to determine a state of the belt tension.

Description

technical field [0001] The invention relates to a device for adjusting belt tension, which can be used for engines mounted on automobiles, etc., and the device includes an auxiliary drive pulley connected to the crankshaft pulley of the engine through a belt, and a tension pulley for adjusting the tension of the belt. , and an automatic tensioner (automatic belt tension adjuster) that adjusts belt tension by changing the position of the center of rotation of a tension pulley by means of an actuator. Background technique [0002] For belt drives that drive additional components of the engine, belt tension adjustment devices are disclosed, for example, in JP 11-82652A, JP 11-8100851A, JP 2002-323101A and JP 2003-27953A. This device has a tension pulley for adjusting the tension of the belt and an automatic tensioner (automatic belt tensioner) constructed so that the tension belt can be moved by moving the moving end of an actuator The position of the center of rotation of the...
