7.1.1. Forward suspension bracket

The forward suspension bracket of the car is based on McPherson's principle, i.e. each wheel has an independent suspension bracket with a separate spring and the shock-absorber. The suspension bracket fastens on a powerful cross beam on which the steering mechanism is also mounted. On this cross beam the lower levers of a suspension bracket mounted in rubber plugs (saylentbloka) are installed. Saylentbloki have the special design providing the high level of comfort and stability at the movement. The lower spherical hinge of a support of a rotary fist is executed as a single whole with the suspension bracket lever. The rotary fist fastens to a spring rack two bolts.
Use of one powerful cross beam makes a lot of room in a motor compartment. The engine is suspended on the right and left internal longerons. For prevention of an inclination of the engine in the longitudinal direction it is fixed in a forward and back part on the central longitudinal beam.
The spherical hinge of a support of a rotary fist rotates in the polyacetate nest impregnated with oil. Such design provides increase in resistance to movement of a spherical support at increase in frequency of fluctuation. At the normal movement of the car the spherical support of a rotary fist is affected by small torque. At the same time steering has high sensitivity. At increase in frequency of fluctuation resistance to rotation in the spherical hinge of a support of a rotary fist increases that reduces fluctuation of a suspension bracket at high speeds.
The lower levers of a suspension bracket are suspended to a cross beam on saylentbloka. The imagined forward axis passes through a forward saylentblok. This design increases sensitivity of steering, and also promotes absorption practically of all fluctuations arising from roughnesses on the road. It is promoted also by a design of a forward saylentblok. It has high rigidity in the cross direction, but low rigidity in longitudinal (in the direction of the movement of the car).
The back saylentblok of the lever of a suspension bracket also has variable rigidity (high and low). At dispersal of the car of effort wring out a back saylentblok outside and it reacts to this movement strong shock-absorbing influence. It increases stability of the direction of the movement. At the movement on an uneven surface (hollows on roads) efforts on a saylentbloka are directed inside. The design of a suspension bracket will amortize these movements that provides comfortableness at the movement.
