Suspension bracket geometry

The angles of installation of wheels of the car - the general information

The angles 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 the Head Podvesk and steering.

Disorder is called the wheel plane tilt angle concerning a vertical. If wheels are inclined by the upper edges outside, disorder is called positive and vice versa. The size of disorder is measured in degrees. Correctness of adjustment of disorder determines the size and the provision of a spot of contact of protectors with a paving and allows to compensate the changes in suspension bracket geometry happening during commission of turns and at the movement of the car on an uneven paving.

Convergence (convergence) is called data size to each other of forward edges of wheels of the car. Such violation of parallelism of installation of wheels allows to minimize wear of a protector due to prevention of a skid at commission of turns. At zero convergence the distance between forward edges of wheels is equal to distance between their rear edges. The size of convergence of wheels is specified in Specifications of the Head Podvesk and steering. Violation of adjustment of convergence leads to acceleration of wear of protectors of tires due to slipping 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 positive, on the contrary.

The size of limit angles of rotation of forward wheels of the car has to be reduced 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.
