4.3.2. Check and adjustment of angles of installation of forward wheels
|Fig. 4.15. Design of a forward suspension bracket: 1 – rack assembled; 2 – stabilizer of cross stability; 3 – rotary fist; 4 – wheel; 5 – suspension bracket lever; 6 – car body; 7 – power shaft; 8 – draft; 9 – brake disk; 10 – rubber cover; 11 – coupling of the stabilizer of cross stability; 12 – inhaling moment; 13 – not to reuse
Preparation for check and adjustment of a convergence
Install the car in not loaded state on a horizontal surface.
Establish a steering wheel in the situation corresponding to the rectilinear movement.
Check pressure in tires and if necessary bring to norm, check a condition of disks.
Check a condition of elements of a suspension bracket, they should not have damages, deformation, considerable wear.
Check the size of a road gleam at the left and on the right.
|Fig. 4.16. Measurement of a convergence by means of a template
Measure a convergence by a template for measurement of a convergence of wheels of 1 (fig. 4.16)
The convergence has to be in the following limits.
If the convergence does not meet standard, adjust it.
Convergence: 2,0 +2 mm.
Weaken lock-nuts of the right and left tips of steering drafts of 1 (fig. 4.17)
Rotate the right and left drafts 2 on the same quantity of turns for reduction of a convergence in norm. At the same time the right and left drafts 2 have to have equal lengths of "A".
Before rotation of drafts 2 apply jellied lubricant between drafts and covers of a lath so that at rotation there was no deformation of covers.
After adjustment, tighten lock-nuts 1 nominal force of an inhaling.
Moment of an inhaling of a lock-nut of a tip of steering draft (a): 45 N · m.
Make sure that covers of a lath are not overwound.
