26 <strong>Transfer</strong> case 0AQ The chain drive The chain drive transmits the driving torque to the front axle. A specially developed "gear chain" with associated chain sprockets is used. The special shape of the link plate ensures that the chain runs smoothly even at high chain speeds. The layout of the chain link plates, with two different tooth flanks and the relatively high, uneven number of teeth on the sprockets, provides a marked improvement in acoustic quality. The chain drive in the 0AQ transfer case has the following features: – High transferable torque – Constant speed – Smooth running – Maintenance free – High efficiency Attention must be paid to the direction of installation when fitting the chain. The chain must be fitted so that the colour-coded chain link plates are counter to the direction of travel, as shown in the illustration. 363_035
Design and function of the gear chain The gear chain consists of the juxtaposed chain link plates which are continuously joined by two cradle pins. The lateral chain link plates ensure that the chain runs true. This is how it works: Each cradle pin is attached non-rotatably to a row of link plates. Two cradle pins form a so-called cradletype joint. As the chain curves around the sprocket, the chain links roll off the cradle pins. Thus, the chain curves around the sprocket almost without producing any friction. Despite high torque and continuous operation, wear is reduced to a minimum and efficiency isincreased. The chain drive is designed to last the service life of the vehicle. Guide Straight chain Chain link plates Curved chain Cradle pins/ cradle-type joint 363_033 363_034 27
