What is the radius of the disk
For most people, little familiar with thedevice of the car, the phrase "flying out the wheel" is probably something that is associated with emergency situations on the road. However, it is not. Departure of the wheel is an important geometric parameter on which the choice of car disks is based.
The distance of the disk is the distance between the plane of the wheelwhen mounted on a hub and vertical plane of symmetry. This value is measured in millimeters and can be either zero, or positive or negative. If the middle of the wheel is located slightly behind the so-called cantilever plane, then consider the outreach positive. If the middle of the wheel is in front of the plane, then they say about the negative flight. In the event that the plane coincides with the middle, then the flight on the disks is zero. Positive displacement of the disc visually can be recognized by a slightly "sunk" wheel in the wheel arch. With a negative reel, the wheel disc seems to bulge outward.
Departure drive, like many other technicalcharacteristics of car wheels, is a strictly individual parameter for each car. If this value is not observed with the specified set discs, the car body can be damaged, which leads to considerable premature wear. There is a rule among the people that the probability of success is much higher if a disk is mounted, the launch is slightly less than the required one, while mounting a disk with a large outreach is not always successful.
Sometimes there may be some problems withinstallation of disks with a smaller distance. However, this is easily solved by an additional installation of spacers for shock absorbers, which slightly raises the rear clearance. In addition, the oscillations of the values of the outset of the disk within ± 5 mm from the standard value are considered quite acceptable.
If you still installed discs with non-standardfor your car by the departure value, it must be taken into account that the distance from the bearing to the fulcrum on the ground has also changed. And the larger the value, the greater the load will be on the bearing. This is due to the fact that the generated torque will create a load that will exceed the nominal load.
If you choose a fairly narrow disk, thenIt should be noted that the outreach should be slightly larger than the standard one. And vice versa: wide disks - a smaller crash. In the event that you find it difficult to find suitable disks, you should contact a qualified specialist.
Installation of incorrectly matched disks canlead to negative changes in the controllability of the car on the road and reduced ride comfort, rapid wear of the suspension components, as well as changes in their characteristics (turning radius of the wheel, stroke, run-in arm). In addition, the behavior of the steering will change, the track width and fuel consumption will change, which, in the long run, will shorten the life of the car. It should take care not only about the appearance of the car, but also about the safety of passengers inside it.
