ABSTRACT:
A tensioning device for maintaining a predetermined amount of tensioning force on an endless drive belt for a vehicle accessories drive system. A housing is mounted in a fixed position on the vehicle engine adjacent the drive belt. A lever is pivotally mounted on a shaft which is located within the housing and extends generally radially outwardly from the housing and is adapted to move in a belt tensioning direction. A first pair of cylindrical, torsional coil springs is telescopically mounted on the shaft, with the springs being located one on each side of the lever. A second pair of cylindrical, torsional coil springs is telescopically concentrically mounted on the shaft and surrounds the first spring pair. One end of each spring is attached to the housing with the other spring ends being attached to the lever. The spring pairs are placed in torsion and bias the lever in the belt tensioning direction. An idler pulley is mounted on the end of the lever and is moved into tensioning engagement with the drive belt by the torsion springs, or alternately one of the vehicle accessories is mounted on the end of the lever for tensioning the drive belt which is engaged by the accessory pulley. The tensioner construction enables a large tensioning force to be obtained from a relatively small, compact, simple spring arrangement by using three or more torsional springs.
