ABSTRACT:
A hydraulic tensioning device for maintaining a predetermined amount of tensioning force on an endless drive belt for the vehicle accessories drive system. A hydraulic cylinder is adapted to be mounted in a fixed position with respect to the vehicle engine and is operatively connected to the hydraulic fluid system of the engine. A bellcrank mechanism is pivotally mounted on the cylinder and has a belt-engaging idler pulley rotatably mounted on an extended end of one of the levers. The other lever is operatively engaged by the cylinder piston which pivots the idler pulley into tensioning engagement with the drive belt. A check valve is provided in the incoming hydraulic fluid passage of the cylinder and keeps that portion of the cylinder chamber which is located behind the piston filled with hydraulic fluid to maintain a constant predetermined tensioning force on the belt whether the engine is running or stopped, and to provide a shock-absorbing damping action for the idler pulley. The cylinder is connected to the power steering pump of the vehicle to provide a relatively high pressure to the cylinder for activation of the piston.
