Prüfungen für Felgen...

[Loki]

Hat jemand Infos über die Prägung bzw. die Felgenprüfung...

-JIL

und

-VIA

Hab ich jetzt schon auf einigen Serien und Zubehör Felgen gesehen. Soll angeblich ne international anerkannte Prüfung sein (ausser in D wahrscheinlich :rolleyes: ). Mit mehr infos krieg ich damit, vieleicht, meine Rotas eingetragen.

Willst meine ROTAS haben? haben schon ne eintragung
Diese JIL habe ich auch auf meinen rims und die nummer 690. Beim tüv meinte damals einer "das müssen se mindestens haben" :nixweiss:
Klugscheisser wahrscheinlich!

[Loki]

Ja Traglast steht auch noch drauf.

Find meine Rotas schöner. ;D Aber wenn du da ein Gutachten hast (für deine) würd mir das schon helfen...

[Kouki23]

Find meine zukünftigen geplanten Felgen noch schöner

JWL TESTS:

Cornering Fatigue Test (Drum Endurance Test)

The purpose of this test is for checking wheel rim strength and durability. Place a wheel assembly with tire on test equipment. Radial stress is then added to simulate vehicle weight.

Test run 500,000 cycles
After 500,000 cycles inspect for cracks, deformation and any nut loosening.


Radial Load Fatigue Test (Rotary Bending Test)

JWL pass criteria: 100,000 cycles
The purpose of this test is for checking durability of the wheel disc. The spokes and the hub are the first point of weight distribution from the vehicle and spoke strength is gauged by this test.

Place a wheel on testing equipment and by adding bending stress to center of disc –

Test run 100,000 cycles
After 100,000 cycles, inspect for cracks, deformation and any nut loosening.


13 Degree Impact Test

JWL pass criteria: 594 kg

The main purpose of test is for checking strength between rim and disc cross section. The “joint” or the area where the spoke and the rim meet is an important structural area that is subject to great stress. The horizontal weight of the rim and the vertical stress of the spokes meet at this joint and proper structural stability is crucial for a proper wheel.

The wheel assembly is placed with tire tilted 13 degrees from horizontal plane on testing equipment.

A preset weight is dropped on the outer sidewall of tire, thus giving impact to the wheel/tire. Then inspect for cracks, deformation and air leak.

This test is very important for the recent trend of a larger/wider wheel with lower profile tire combination, because there is less air volume than OE wheel/tire and more stress to inner rim section. This test simulates actual usage condition such as hitting corner curb or objects from side.

@Kouki23: War der grüne Racing in Aalen deiner? Schick mir mal bitte bezügl. der Felgen eine PN.
