Whee Measuring 4c Whee Measuremen HOW TO MEASURE MINIMUM DUAL SPACING Minimum dua spacing measuremen is deermined by he yre manufacurer and may be obained from he yre manufacurer s handbook.

If he doubed ouse measuremen is equa o or greaer han he yre manufacurer s recommendaion, here wi be sufficien minimum dua spacing. Whee inse and ouse is given for each Xie or Chevron whee on he Whee Specificaion Shees (See pages 18, 19 & 23).

Produc Awareness 4e Whee Hubs REGULAR HUB HAS A CONTINUOUS DIAMETER STAR SHAPED HUB HAS LESS SURFACE CONTACT NON-CIRCUMFERENTIAL HUBS CAN DAMAGE CV WHEELS Our esing faciiies have found ha commercia vehice whees operaing on spider and sar shaped hubs are suffering unesed oad sresses which are causing cracks and having ife expecancy, furhermore, hese hubs may poeniay compromise he faigue ife of he whee. The hub shape pays an imporan par when i comes o he performance of Truck and Traier Whees. Anaysis done by he members of he Associaion of European Whee Manufacurers (EUWA) show ha he severa vehices esed, (no incuding he hubs as described above) prove ha here are various shapes ha exis which are no coninuous bu have a dened shape or sar shape. PARTIAL CONTACT CAUSES LOCALISED STRESS Modern whees for rucks and raiers are designed and fabricaed according o European sandards concerning e.g. rim profie, whee fixaion or a faigue es procedures which means hose sandards have he inenion o make sure as possibe ha whees can be mouned and inerchanged beween equivaen vehices wihou poenia safey risks. A presen a quaiy whees are ried and esed o European Tyre and Rim Technica Organisaion (ETRTO) sandards on a circumferenia hub wih a coninuous conac diameer, which is universay acknowedged as he main crierion by he EUWA. However, he inroducion of noncircumferenia hubs, which give ony paria conac beween he axe and whee, is causing ocaised sresses in he whee ha are amos wice as high as he indusry approved fu conac hub. CONTINUOUS DIAMETER One imporan poin is he fixaion of whees which is defined in he sandards ISO 4107 Commercia Vehices - Whee Hub Aachmen Dimensions, in DIN 74361-3 Disc Whees - Dimensions and Fasening Devices for Hub Cenring and in SAE J694 Disc Whee/Hub or Drum Inerface dimensions Those sandards define he ouer hub shape as a coninuous diameer. STAR SHAPED OR SPIDER HUBS As a precauion, and in order o ry o undersand he poenia impac of differen hubs, WIL have esed whees using a varian of sar shaped hubs. Even hough he whees passed he corresponding ess successfuy, reduced faigue ife has been experienced and his is due o higher oca sresses caused by he aachmen face shape and diameer reducions of he sar shape. WARRANTY PRECAUTIONS The repercussions of he research wi be numerous. Operaors wi be required o conac hub and whee manufacurers as producs originay repaced or refunded under warrany may no onger be considered if he produc is shown o have operaed on a spider or sar shaped hub. WHAT TO LOOK OUT FOR... Look for crack sarers on he aachmen face side aong he edges of a sar shaped hub and coninue furher observaion because hese iniia cracks coud poeniay cause circumferenia cracks. There are some sar shaped hubs ha have sharp ouer edges and his design encourages he deveopmen of hese iniia cracks. Aso, due o he differen characerisics of some of he sar shapes (differences beween axe manufacurers); poenia imprins can show differen shapes. In he case of mouning hese whees on hubs wih ye anoher shape, he drasic reduced aachmen area can ead o an increased surface pressure and an undefined aachmen of whee o hub. Negaive infuences incude reduced service condiions ha can cause cracks such as he connecion area beween he whee and hub; such cracks coud poeniay occur a an earier sage of he enire vehice faigue ife. In order o maximize safey, EUWA sricy recommends for he vehices equipped wih non-circuar hubs in he fied be checked for cracks on he inner and ouer aachmen face every 50 000km. Where here is crack deecion, hose whees mus be repaced immediaey. Where here are cases of crack deecion and necessary whee change, he hubs shoud aso be checked for wear ou and cracks and if necessary repaced. 43
