CV-joint

( Constant Velocity Joint ) Ceann de na háiseanna beaga círcleacha ag deireadh achsa ar bhus . Tá ceathrar de na háiseanna seo ag busaí, Vanagons, agus EuroVans, agus tá ochtar acu ag Syncro Vanagons. Tá siad riachtanach chun ligean don achsa bogadh suas agus síos fós ag casadh chun an carr a thiomáint. caithfear na naisc a choinneáil glas chun feidhmiú go maith. nuair a bhíonn siad caite, déanann siad torann cnagach a bhuaileann scáth ar chroíthe úinéirí bhus gach áit.

( Constant Velocity Joint ) One of the small circular devices at an end of an axle on a bus . Buses , Vanagons , and EuroVans have four of these, while the Syncro Vanagons have a total of eight. These are necessary to allow the axle to move up and down while still turning to propel the car. the joints need to be keep greased to function properly. when they are worn, they make a knocking-noise that strikes fear into the hearts of bus owners everywhere. Microbuses do not have CV joints, but use a 'swing-axle' and reduction gear box instead.
