Driving shaft/semi-axes, general information and condition check
Zadny Bridge of the car has a gipoidny design of the semi-unloaded type (the axis of a leading gear wheel passes below an axis of a conducted gear wheel of the main transfer). During commission of turns the differential provides to an external wheel rotation possibility with greater speed, than speed of rotation of an internal wheel. The internal ends of semi-axes are equipped with the shlitsa entering into gearing with shlitsa of naves of lateral gear wheels of differential, therefore, during commission of turns internal (on turn radius) the lateral gear wheel also rotates more slowly than the external. Planetary assembly thus starts to rotate in a differential box. The differential is placed in the cast case which equipped with a stamped cover and has received the name of the holder. Steel pipes of semi-axes are pressed in the holder and scalded.
On all-wheel drive models completely independent forward suspension bracket is used. The bridge is educated by assembly of differential and pair of the power shafts equipped with internal and external hinges of equal angular speeds (CV JOINT).
On some models the back bridge is equipped with the being blocked differential of limited sliding. Such differential works in a mode of usual planetary assembly until one of wheels does not start to revolve. The structure of assembly includes pair of the conic couplings which are slowing down rotation of a box of differential in a similar situation. The taking place difference of angular speeds of rotation of wheels leads to increase of load of satellites of planetary assembly which via the conic coupling jointed with a semi-axis is transferred on being in gearing with a paving a wheel.
Often suspicions on failure of components of one of bridges appear unreasonable, and a source of emergence of taking place symptoms lies in violation of serviceability of functioning absolutely other components of the car. Try to estimate with all attentiveness a situation, serially excepting all possible causes of failure.
Emergence listed below characteristic extraneous sounds often wrongly associates with violation of serviceability of functioning of a drive of wheels:
In view of need of use of special tools, it will be more correct to charge performance of regenerative repair of differential to specialists of car-care center. Descriptions of procedures of removal are provided in below-mentioned Sections of the present Chapter and installation of semi-axes / power shafts, replacement of epiploons of differential, replacement of bearings and dismantle of all assembly of a drive of wheels for the purpose of performance of its regenerative repair or replacement.
