The damper funct ions by rest ricti ng the flow of hydraul ic fluid through internal gall eri es wit hin t he damper. The damper rodmoves axi all y wit hin t he damper, i ts movement l imi ted by the flow of flui d t hrough the gal leri es, provi di ng damping ofundul ati ons i n t he t errai n. The damper rod is s ealed at i ts exi t poi nt from t he damper body t o mai ntain the flui d wit hin theunit and t o prevent the i ngres s of dirt and mois ture. The seal als o i ncorporat es a wiper to keep t he rod cl ean.
The damper rod i s located t hrough a central hol e in the top mount as sembl y. The rod i s threaded at i ts out er end. As elf-locking nut s ecures the t op mount t o t he damper rod. A s pring ai d i s fi tt ed t o t he damper rod t o prevent the t opmount cont act ing t he t op of the damper duri ng ful l s us pens ion compress ion and al s o as si st s t he s uspens ion t une. A bootis fi tt ed between t he damper body and t he t op mount and protects the damper pis t on rod from damage.
The coi l s pring fit t ed differs wit h vehi cl e s peci fi cat ion. Each s pring i s col our coded to identi fy i ts rat ing and fit mentrequirements .
The coi l s pring i s l ocated in a spring s eat which i s an int egral part of the damper body and cont ains a spring i sol at or. Thedesi gn of the spring s eat prevent s t he s pring rotat ing. The s pring has a li near rate compres s ion and i s i ncli ned to count ercorneri ng forces . The oppos it e end of t he coi l spring i s als o l ocat ed in a s pring isolator whi ch is fit ted i n t he t op mountas sembl y. Bot h s pri ng is olat ors are made from rubber and prevent any nois e produced during damper and s pri ngcompres si on/extens ion from bei ng t rans mit ted to t he vehicle body.
The t op mount is fit ted wit h a t op mount bearing whi ch is l ocat ed between t he 2 t op mount plat es and the damper rod. As elf locking nut s ecures the damper rod to the t op mount. The t op mount bearing reduces s t eering resi s tance bypreventi ng the s pring from 'wi ndi ng' up when t he s teering i n t urned. The t op mount att aches t o a st rengt hened t urret ont he chas s is wi th 3 int egral st uds and s elf-locking nut s.
Two brackets are welded t o t he damper body. One bracket provides for t he att achment of t he s tabil izer li nk. The s econdbracket provi des for t he att achment of t he brake hose and wheel s peed s ens or cabl e.
