Straight axles are alined without changeof contour, whereas dropped axles have a distinct bend ordrop in the center, or are curved downward throughouttheir entire length in the form of a sweeping arc. Withthe dropped form the spring pads may be lowered to securea better alinement of the engine and driving shafts andlower the center of gravity. They also permit the use standard Elliott type is generally used on motor truckaxles, and the inverted Elliott is found in industrial trucksand some tractors. Rear Axles .Rear axles (see also Final Drive) are of two principaltypes, i. e. dead axles and live axles, the latter being. Fig. 1—Straight Type Front Axle of large diameter wheels without increasing the height ofthe chassis frame above the ground. Front axles are assembled as complete units with steer-ing knuckles, wheel spindles, bearings and steering rodsattached. Steering knuckles are designed in two typesnamed from their designers, Elliott and Lemoine. Amodification of each type is found in the InvertedElliott and Inverted Lemoine forms, which are usedto some extent in passenger car design. The distinctive produced in various modifications as described, that isPlain Live, Semi-Floating, Three-Quarter-Floating andFull-Floating axles. Dead Axles Dead axles are those which have no moving parts andserve merely as load carrying members, the wheels beingturned by some connection outside the axle proper.
