The general information
Cars KIA Sportage are the typical representative of off-road cars of class Part Time 4WD, i.e. with a connected full drive. As a rule on such cars there is no interaxal differential that limits use of an all-wheel drive mode only to traffic conditions on a cross-country terrain and roads with a slippery or friable covering. Attempts of activation of a mode 4WD on a dry asphalt covering are interfaced to risk of failure of a distributing box and inevitably reduce service life of tyre covers.
The basic leading bridge on KIA Sportage is back. At need occurrence there is a possibility rigid (the interaxal differential is absent) connections of the forward bridge. In case of need the all-wheel drive mode can be added by inclusion of a reducer of a distributing box (a mode 4L). Naves free are equipped automatic муфтами a free wheeling: mechanical or, - in last updating, - vacuum. Муфты are connected automatically at inclusion of an all-wheel drive mode, and an indispensable condition of connection mechanical муфт is the start of motion (проворачивание forward wheels), - considering the given feature, on the cars equipped mechanical (обгонными) муфтами, necessity for transition to an all-wheel drive mode should be predicted in advance. Nevertheless, we will notice that in practice mechanical муфты prove to be as much more reliable (especially in the strengthened execution), rather than vacuum which in the Russian climatic and road conditions quickly enough become unfit for use.
The present Chapter is devoted components трансмиссионной to a line, located between a back part of the engine and car driving wheels (excluding RKPP/AT, - Heads the Five-step manual box of a gear change and Automatic transmission accordingly see). According to the destination considered components can be broken into four categories: coupling (models with Manual transmission), a distributing box, карданные shaft and the assemblages of forward and back bridges equipped in the differentials. Descriptions of a design and a principle of action of each of separate knots, and also procedures of check of a condition, removal/installation and service of components entering into all four groups are more low resulted.
