Corners of installation of wheels

Corners of installation of forward wheels define geometry of provision of the last concerning a car and paving suspension bracket. Violation of adjustment of this geometry conducts to decrease in controllability of the car and increase of speed of wear of tires. Into number of subjects to control of corners of installation of forward wheels of the car enter disorder, выбег (a corner of a longitudinal inclination of an axis of turn of a wheel) and convergence (see an illustration below).

One of parameters – convergence, and, both forward, and back wheels of the car is subject to adjustment only. Sizes of disorder and выбега forward wheels should be checked on a regular basis for an assessment of degree of wear of components of a suspension bracket and a steering drive.

Adjustment of corners of installation of wheels is among demanding special accuracy of measurement of procedures for which high-quality performance existence of special, rather bulky and expensive equipment is necessary. It will be most correct to charge performance of this work to professional mechanics of car-care center. Below, for the general understanding, definitions of each of under control corners of installation of wheels of the car which knowledge will facilitate communication of the owner of the car with the car-care center personnel are given.

The data size to each other forward edges of wheels of the car is called as convergence. Such violation of parallelism of installation of wheels allows to minimize wear of a protector for the account юза at commission of turns. At zero convergence distance between forward edges of wheels equally to distance between their back edges. Normal convergence (X – Y) – see an illustration – usually does not exceed inch shares (1 inch = 2.54 cm). Adjustment of convergence of forward wheels is carried out by adjustment of length of steering drafts. For adjustment of convergence of back wheels it is necessary to correct position of compensatory levers of a suspension bracket in the arms on the car bottom. Violation of adjustment of convergence conducts to acceleration of wear of protectors of tires at the expense of a proskalzyvaniye them on a paving.

The tilt angle of the plane of wheels concerning a vertical is called as disorder. If wheels are inclined by the upper edges outside, disorder is called as positive, and on the contrary. The size of disorder is measured in degrees. Correctness of adjustment of disorder defines size and the provision of a spot of contact of protectors with the road and allows to compensate changes in suspension bracket geometry during commission of turns and at car movement on a rough paving.

Vybegom is called a deviation corner from a vertical of an axis of turn of a wheel in the plane of the last. If the axis of turn is inclined back, выбег is called as positive, on the contrary.
