Suspension bracket geometry

Corners of installation of wheels of the car - the general information

Corners of installation of wheels considerably influence stability of the car, wear of tires and fuel consumption. Nominal rates of corners are specified in Specifications of Head the Suspension bracket and a steering.

The tilt angle of the plane of a wheel 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 a paving and allows to compensate changes in geometry the suspension brackets occurring during commission of turns and at movement of the car on a rough paving.

The data size to each other forward edges of wheels of the car is called as convergence (convergence). Such violation of parallelism of installation of wheels allows to minimize wear of a protector at the expense of prevention юза at commission of turns. At zero convergence distance between forward edges of wheels equally to distance between their back edges. The size of convergence of wheels is specified in Specifications of Head the Suspension bracket and a steering. Violation of adjustment of convergence conducts to acceleration of wear of protectors of tires at the expense of a proskalzyvaniye them on a paving.

Vybegom is called a corner of a longitudinal inclination of an axis of turn of a wheel, i.e., a corner of a deviation of this axis from a vertical in the rim plane. If the axis of turn is inclined back, выбег is called as positive, on the contrary.

The size of limiting angles of rotation of forward wheels of the car should be lowered at increase in the size of the last.

The general check of geometry of a suspension bracket is made at the special stand in the conditions of a specialized workshop.
