Corners of installation of wheels
Optimum qualities of movement and the smallest wear of tires are reached only at the correct installation of forward wheels. At abnormal wear of tires, at a bad continence of the road - at bad keeping of the direction, and also at bad controllability on turns - it is necessary to address in a workshop for car check by optical means.
Measurement of corners of installation of wheels is impossible without special measuring devices. Therefore we will be limited here only to the description of the main concepts necessary for measurement.
Convergence/disorder / cross-section inclination of an axis of turn of a wheel / longitudinal inclination of an axis of turn of a wheel (выбег)
The convergence is understood as lateral distance between wheels. Forward wheels, as a rule should have a positive convergence as wheels at the expense of disorder and resistance to a kacheniye run up a little outside as in bearings of naves, a suspension bracket of wheels and tips of steering drafts is available люфт. The positive convergence means compensates aspiration of forward wheels to run up outside. At a positive convergence of a wheel are established so that, measuring at height of an average point of a wheel in front are located more closely to each other than behind.
Disorder and cross-section inclination of an axis of turn of a wheel reduce transfer of blows from the road by a steering and support the smallest friction at movement on turns.
Disorder — is a corner on which the surface of a wheel deviates vertical management. Forward wheels stand thus under an inclination, at negative disorder, for example, wheels in points of fastening will defend from each other further than above. The cross-section inclination of an axis of turn of a wheel is a corner of a beta inclination between an axis of a rotary fist and the vertical which has been carried out through a point of fastening of a wheel, looking in the longitudinal direction.
At the expense of corners of disorder and a cross-section inclination of an axis of turn of a point of a contact of wheels with the road settle down closer to an axis of a rotary fist. It supports by the smallest a so-called shoulder of a running in. The running in shoulder less, the management is easier. Also blows from the road make weaker impact on a steering. The longitudinal inclination of an axis of turn of a wheel (выбег) is a corner between an axis of a rotary fist and a vertical in a point of fastening of a wheel, looking in the cross-section direction of the car. Выбег makes considerable impact on movement of wheels on a straight line. Too small выбег causes a deviation from the set direction at movement on bad streets or at a lateral wind and does not allow to return to a steering after passing of turn to a starting position. On the other side of big выбег increases force of management.
Выбег, disorder and a cross-section inclination of an axis of turn of a wheel on MAZDA 323 can be checked only, they are not subject to adjustment. If the measured sizes lie out of area of admissible limits, details of a suspension bracket are damaged or worn-out.
The viewing hole or the lift is necessary for check of corners of installation of wheels with a platform. At each measurement should be satisfied the following conditions.
