Fig. 4.4. The spherical hinge with low factor of a friction: 1–forward top lever; 2–the low-viscous spherical hinge (for the forward top lever); 3–forward bottom lever (back); 4–rotary fist; 5–the back spherical hinge with low factor of a friction (for the forward bottom lever); 6–the forward spherical hinge with low factor of a friction (for the forward bottom lever); 7–forward bottom lever; 8–sectional view
The spherical hinge with low factor of a friction is used on a rotary fist of the forward top and bottom lever (ов) to improve a response of a steering and smoothness of work (fig. 4.4).
