4.1. General information

Forward and back suspension brackets are developed specially for the Mazda 6 (GG) car and have some features.
Forward suspension bracket – on double cross-section levers, the bottom lever is equipped with two floating hinges.
Back suspension bracket – multilever type E.
Shift шкворня concerning the center of a wheel of a forward suspension bracket is minimized. The forward top lever and both bottom levers are equipped with spherical hinges with low factor of a friction. The width of a track is increased by 50 mm in comparison with previous model. It is equivalent to fall of the center of gravity of the car on 20 mm. As a result stability of management at movement on turn improved.

Features of a platform of the car
Fig. 4.1. Features of a platform of the car: 1–center of gravity; 2–it is reduced by 20 mm; 3–height; 4–width of a track (626); 5–width of a track (Mazda 6); 6–it is increased by +50 mm

The axis of rotation is established a little obliquely. The forward shock-absorber is equipped with a spring of a course of a release. For the shock-absorber the separate support is used. to increase rigidity of a design, the forward cross-piece and the amplifier for adjustment of disorder of back wheels are established. Cross-section draft and the bottom lever have a special cam and the coupling coupling (fig. 4.1).

Installation of height of the center of a list of the car
Fig. 4.2. Installation of height of the center of a list of the car: 1–height of the forward center of a list; 2–height of the back center of a list; 3–rotation axis; 4–line continuation (it is parallel to the basis) from height of the forward center of a list

The geometry of a platform allows to place a roving axis (an invisible vertical axis concerning which the vehicle reacts to operating action of the driver) in the vehicle center. The height of the forward center of a list is less, than the back center of a list. Management at rectilinear movement improves at the expense of installation of an axis of rotation at a small angle (fig. 4.2).

General information

*1 Cooling liquids of the engine and engine oil – at the specified level. The fuel tank is completely filled. The spare wheel, a jack and the tool are on regular places.
*2 Difference between left and right wheels should not exceed 1°30'.
*3 Distance between the center of a wheel and edge covered the following:
before – 402 mm.
the back – 392 mm.
