arrangement keeps the two members spaced apart this allows each member to bend and flex when subjected to longitudinal forces as transverse loading occurs the two members are caused to move together and eventually abut one another this abutment greatly increases the overall strength of the control arm allowing it to withstand severe transverse forces without buckling application_number US 45585499 A description referring to fig1 the two piece control arm 20 of the present invention is shown in the context of a rear independent suspension system 8 the rear cradle 10 forms a portion of the frame of the vehicle wheel drum housing 12 supports the braking assembly and wheels for the vehicle wheel drum housing 12 is attached to rear cradle 10 and is aligned with the rear axle line 16 as shown three control arms connect the wheel drum housing 12 to the rear cradle 10 rear control arm 20 suspension link 20 upper control arm 22 and front control arm 23 a spring 14 and shock absorber not shown are coupled to front control arm 23 to absorb vertical displacement of the wheel drum housing 12 whereas the suspension link 20 and upper control arm 22 are able to freely pivot in this direction the front of the vehicle is indicated as shown suspension link 20 must be designed to handle the three disparate forces indicated.
