Williams FW33 – Innovative rear suspension



The ultra low rear end of the Williams FW33 (2011 car) effected the rear suspension design dramatically. The totally new rear suspension is a pull rod design in contrast to the previous push rod and the innovative of this new configuration is that  the top wishbones ( in yellow)  attach directly onto the rear wing’s single pillar , something novel for F1 .



      The unusual and innovative rear suspension assemble caused excessive vibration to the rear  wing , something totally unwanted because it dramatically reduces aero efficiency of the car . To decrease wing’s lateral movement and provide extra stiffness Williams supported the beam wing onto the pillar ( in yellow , first image ) via a connector .Furthermore in the first 2011 race at Melbourne , to totally overcome any vibration issue , the endplates were mounted onto the diffuser roof via single metallic pillars (second illustration ,red arrow) .

    Very interesting idea.
    I really enjoy reading your articles and the drawing are awesome. The drawings very clearly explain the changes.
    One request, would it be possible for you to post an actual picture of what you are showing. Or atleast a link to a photo.
