ABSTRACT:
A drive configuration for driving one or more rotating sprockets (e.g., of an engine drive train), including a flexible force transmitting member forming a closed curve enclosing an area; a drive sprocket situated outside the area and driving the force transmitting member; first and second pulleys situated at least partially within the area and on opposing sides of the drive sprocket so as to urge the force transmitting member against the drive sprocket; and one or more driven sprockets each coupled to the force transmitting member. The drive configuration may include a cartridge including a base, one or more secondary pulleys being situated on opposing sides of the first pulley such that a timing belt is urged into contact with a drive sprocket and each of the pulleys. Accordingly, a timing belt may be rapidly installed or removed by inserting or removing the cartridge according to the present invention.
