The s teeri ng gear, manufactured by Vis t eon, i s located at t he rear, top face, of t he front subframe. It is s oli dl y bolt ed t ot he subframe wit h t wo bolt s. The bolt s are pass ed t hrough from the unders ide of t he s ubframe, t o i mprove s ervi ce access ,and are screwed into threaded bos s es on the st eering gear body.
The s teeri ng gear is a convent ional end take-off, rack and pi ni on power as s is t ed unit wi th l ock to lock requiring 2.6 turnsof the st eering wheel . Thi s gives a s t eering rati o (rat io of s t eering wheel angl e t o road wheel angl e) of 16.7:1 whi chprovides very qui ck and res pons ive react ion t o driver inputs . The s teeri ng gear features large di ameter t ie-rods whichopti mize feedback and feel t o t he driver.
The s teeri ng gear compris es a s t eel , welded and machined, one pi ece hous ing whi ch cont ai ns a mechanical s t eering rack, avalve unit and an i ntegrat ed hydraulic power unit . The s teeri ng gear us es a rack with an i nt egrat ed pis ton whi ch is gui dedon plai n bearings wi thi n t he rack hous i ng. The pi ni on, whi ch is at tached t o the val ve uni t, runs in bearings and mes heswit h t he rack t eeth. The rack i s pres s ed agai nst t he pini on by a s pri ng loaded yoke which ensures that t he teet h mes hwit hout any pl ay. The pi ni on is connect ed t o t he val ve unit via a tors ion bar. The rotary moti on of the st eeri ng wheel i sconvert ed i nt o l inear movement of t he rack by t he pinion and is i nit iated by the valve uni t. This movement i s transferredint o movement of the road wheel s by adjus t abl e t ie-rods.
The pis t on of the hydrauli c power uni t is l ocat ed at one end of the gear hous ing. Each s ide of t he pis ton i s connected tofl uid press ure or fl ui d ret urn vi a external met al pipes which are connected t o t he valve unit . Each end of t he gear has at hreaded hol e which provi des for the fi tment of t he ti e-rod. The external ends of t he st eeri ng gear are s eal ed wit h bootswhich prevent t he ingres s of dirt and mois t ure and al low for verti cal movement of the t ie-rods wi th the s us pens ion inaddi ti on t o li near movement when t he s teeri ng wheel i s t urned.

The principl e functi on of the val ve uni t is t o provi de poweras si st ance (i .e. when parking) t o opti mize the effort required to turn the st eering wheel . The pi nion hous ing of t he val ve isan i nt egral part of t he main st eering gear as sembl y.
The pinion hous ing has four machi ned ports whi ch provide connect ions for pres s ure feed of t he power s t eering pump,ret urn flui d t o t he res ervoir and pres s ure feeds to each s ide of t he cylinder pis t on. A non-ret urn valve and s eal is fit ted int he pres sure feed port from t he power st eeri ng pump. The val ve uni t compris es an outer s l eeve, an input s haft, a torsi onbar and a pinion shaft.
The valve unit i s co-axial wit h t he pinion shaft whi ch is connect ed t o the st eeri ng col umn via the i nput s haft . The val veunit component s are locat ed in the st eering gear pini on hous ing which is sealed wit h a cap. The out er s leeve is l ocat ed int he main bore of the pi nion hous ing. Three annul ar grooves are machined on i ts out er di ameter. PTFE rings are locatedbetween t he grooves and s eal agains t the bore of the pi nion hous ing. Hol es are dril led radiall y in each annular groovet hrough the wal l of the s leeve. The bore of t he out er s leeve is machined t o accept the input s haft .

The ends of the s lot s are cl osed and do not conti nue to the end of t he outer s leeve. The radial holes i n the out er sl eeveare dril led i nto each s lot . The input s haft has two machi ned fl at s at i ts out er end whi ch all ow for t he att achment of t hes teeri ng column i ntermedi ate shaft yoke. The fl ats ens ure t hat the intermediate s haft is fit t ed in t he correct pos it ion t omaint ain t he opti mum phas e angle. The inner end of the input shaft forms a dog-t ooth whi ch mates wit h a s lot i n t hepinion shaft.

The pump is locat ed at t he front of t he engine and i s dri ven by the Front Engine Auxil iary Dri ve (FEAD) Poly Veebelt which i s direct ly driven from the cranks haft . The out put from t he pump i ncreas es proporti onall y wi th the l oad appl iedt o the st eeri ng val ve uni t. A s el f-adjus ti ng tens ioner is fit t ed to maint ai n t he correct t ens ion on the bel t.
The pump consi st s of a cart ridge s et which cons is t s of 11 vanes and a rot or. These are mount ed on t he input s haft and ares urrounded by a variable di spl acement cam ring. The vanes rotat e wit hin the cam ri ng and are driven by t he s haft. As thevanes rotat e, the cam ri ng caus es the space between t he vanes to increase. This causes a depres si on between t he vanesand fl uid i s drawn from t he res ervoir vi a t he suct ion hos e int o t he s pace between the vanes. As t he s haft rotat es , t he inl etport i s clos ed to the vanes which have drawn in fluid, t rapping t he fluid bet ween t he vanes . The cam ring caus es t he s pacebetween t he vanes to reduce and cons equenti ally compress es and pres s uri zes t he hydrauli c fl ui d t rapped between t hem.Furt her rotat ion of t he s haft moves the vanes t o the out let port . As t he vanes pas s t he port plat e, the pres s uri zed fl ui dpass es from the pump out let port into the press ure hose to the s t eering gear.
The cam ring can move wi thi n t he val ve body. By moving the cam ri ng it i s poss ibl e to vary t he eccentricit y of t he s haftand t he vanes i n rel ati on to the cam ri ng. As t he eccent rici ty i s decreased, t he volume of hydraulic flui d t rapped bet weent he vanes decreases , mai nt aining a cons t ant flui d output. This reduces t he power and torque required to turn t he pumpand t herefore improves engine economy. The pump has an int ernal regulati ng valve which controls t he eccentricit y of t hecam ring and t herefore vari es the flow rat e accordi ng to demand.
At low engi ne s peeds , the i nternal dis placement of the vari able di spl acement pump i s at it s maximum t o generate thecont rol led fluid out put. As t he pump s peed increas es wit h engine s peed, t he i ncreas ed flow ins ide t he pump generates aback press ure wit hin the pump. This back pres s ure causes an internal regul ati ng val ve to move t he the cam ri ng andreduce t he int ernal di spl acement of the pump to maint ian t he cons t ant flui d fl ow from the pump.

3-Pres s ure out put port (t o s t eering gear val ve unit )
The pump i s a fixed dis placement, vane type pump which s uppl ies hydrauli c pres sure to t he st eeri ng gear valve unit .

The pump contains a number of vanes which rot ate wit hin a cam ri ng and are driven by t he i nput s haft . As the vanesrot ate, t he cam ring causes t he s pace bet ween the vanes t o increas e. Thi s caus es a depres s ion bet ween the vanes andfl uid i s drawn from t he res ervoir vi a t he suct ion hos e int o t he s pace between the vanes. As t he s haft rotat es , t he inl etport i s clos ed to the vanes which have drawn in fluid, t rapping t he fluid bet ween t he vanes . The cam ring caus es t he s pacebetween t he vanes to reduce and cons equenti ally compress es and pres s uri zes t he hydrauli c fl ui d t rapped between t hem.Furt her rotat ion of t he s haft moves the vanes t o the out let port . As t he vanes pas s t he port plat e t he pres surized fluidpass es from the pump out let port into the press ure hose to the s t eering gear.
The pres s urized fluid is s ubject t o cont rol by a flow cont rol and pres s ure relief valve. The fl ow control valve maintai ns acons t ant flow of flui d s uppl ied t o t he s teeri ng gear irres pecti ve of engi ne s peed variati ons . The pres s ure reli ef val ve limit st he maximum pres sure on t he output s ide of t he pump. A met eri ng orifice i s included i n t he dis charge port of the pump.

The pres sure rel ief valve wi ll operate if t hedis charge from the pump is rest ri ct ed, for example, s teeri ng held on full l ock. If the output from the pump is bl ocked, al loutput is recirculat ed t hrough the pump. In t his condi ti on, as no fresh fl ui d i s drawn i nto the pump from t he res ervoir, thefl uid t emperat ure i nsi de t he pump wil l increas e rapi dl y. Cons equent iall y, periods of operati on of the s t eering gear on ful llock s houl d be kept to a mi nimum to prevent overheati ng of the pump and the flui d within it .
