Why is the car razval, shojdeniya?
The terms razval and skhojdeniya are considered the most important processes in the automotive industry. Razval is a term that indicates how upright a wheel is, while skhojdeniya is a term that indicates that the front edges of the wheels are closer to each other than the rear edges, or vice versa. In both cases, depending on the position of the wheel, it is called negative or positive curvature.
If the wheels go from an upright position to a negative camber, the inner edges of the tires will wear faster because more weight falls on that side. Negative camber is used in sports cars, which keeps the car in good contact with the road at high speed and stability, that is, it does not roll to the side. But driving in such a state will have a negative effect on the bearings or the suspension.
If the wheels go from an upright position to a positive camber, the outer edges of the tires will be eaten away quickly. Positive curvature has an off-road feature, that is, it is perfect for walking on uneven surfaces filled with large stones. If you load heavy things on pickup trucks, the positive camber returns to the upright position, which is very convenient for the truck.
Razval and shojdeniya in our workshops are done to return these wheels from these positive or negative curvatures to their previous upright or normal position. Because the only standard for all cars in normal operation is that the wheel is in an upright position.
