【正文】 ? rder Fahrwerktechnik AG). 如果螺旋彈簧上的力 F 和導向鉸 G 上的力作用線不落在減振器中心線上，則彈簧柱與車身連接的點 E上始終有橫向力 EyF 的作用。這個力在活塞導向套和活塞桿上引起反力 CyF 和 KyF 。 CyF = EyF + KyF ， CyF 這個力愈大，作用在活塞導向套上的摩擦力 rF就愈大，從而使得推活塞桿下落所需的垂直力也要變大。 活塞頭具有較大的直徑，而且是在油中滑動。所以橫向力 EyF 在此僅起次要作用，而更小的力 KyF 就幾乎沒有什么影響。通過把彈簧斜置，可以減小力 CyF 。 If lateral force wzF, moves lever arm b round guiding joint G, the lateral force spF continually acts in the bodyside fixing point E of the McPherson strut as a result of the force EYF. . This generates the reaction forces CYF. and KYF. on the piston rod guide and piston. This is CYF. + EYF. = KYF. and the greater this force bees, the further the frictional force frF increases in the piston rod guide and the greater the change in vertical force needed for it to rip away. As the piston has a large diameter and also slides in shockabsorber fluid, lateral force KYF. plays only a subordinate role (see ). KYF. can be reduced by offsetting the springs at an angle and shortening the distance b (see Figs and , and Equation ).

As large a distance as possible is needed between points 6 and 14 on the wheel hub carrier to ensure unimpaired straight running. The fixing points 13 of the longitudinal links 16 are behind the wheel centre, exactly like mounting points 17 of the antiroll bar 18. The back of the antiroll bar is flexibly joined to the body via tabs 19. The additional springs 10 attached to the top of the McPherson struts are covered by the dust tube 20. The crossmember 15 helps to fix the assembly to the body. An important criterion for dimensioning the control arm 16 is reverse drive against an obstruction. most the lack of space prevents wider tyres being fitted. If such tyres are absolutely necessary, disctype wheels with a smaller wheel offset e are needed and these lead to a detrimentally larger positive or smaller negative kingpin offset at ground or ( and ).
