    4 link MK1 with inboard turrets SATCHEL LINK

    Hi
    Has anyone any information they can share on this type of 4 Link?. The correct term for it (Ive been told) is a 'Satchell Link' I believe it was used on some of the early Mk1's and possibility on all of the world cup cars. There is a guy in Australia that has it fitted to a MK1 twin cam.
    Any information on it's use or car that have it installed is appreciated.

    James

    This is the basic setup, however it has leaf springs

    Can't see how that functions with the tie rod mounts in different places requiring them to pivot / travel in different arcs?
    Tramp bars and a panhard is less complicated and works.

    Show me where they did? The Works cars started with short parallel radius links, then changed to long arm set-up, either with panhard or watts linkages = 5 or 6 link set-up. These were either with slipper leaf springs or coil over shocks in turrets close to the regular axle mounted location.

    If you google satchell link and go on Locost builders site there is an article on there about such a set up
    Cortina mk3/4/5 and Vauxhall viva HB/C are loosely based around this principal

    Surprised to see a panhard rod on that set up, the angled top links the way I understood it was to remove the necessity for it ?

    Wrong in so many ways, not as in period, it's a fully floater for starters. May correct reg but not the same as it was. No panhard rod , not used until mk2s

    Colr6 is correct no need for Panard rod with angled links (its the whole point of them), These are the pictures Oakfields posted when they advertised the car a couple of years back. But this style of 4 link set up is correct for those world cup cars.

    are you going to be using it as things have moved on since,
    panard rod could be fitted to bring the roll center back to the center of the diff

    Quote from the sale of FTW48H.......
    The rest of the drivetrain was equally “bomber,” with an overdrive 5-speed ZF transmission and a limited-slip Atlas third member. The rear suspension was basically normal Escort, but with the addition of rather weird diagonal radius rods that appear to have been intended more to keep anything else from breaking than to improve handling. It was a conservative but effective approach. Mikkola in FEV 1H won, and all five cars finished in the top ten.
    From the photograph and from the description above, these axles don't appear to be 4 linked as shown in your diagram so my comments from #3 stand

    Re: 4 link MK1 with inboard turrets SATCHEL LINK

    I'm building the car to an Historic spec. This requires i return it to build it to a specific point in time, where the configuration is know and can be proven. I'm not suggesting a traditional but more modern,4 link would 'Probably' work better than this. I really don't have a choice for the FIA Appendix K, HTP I can prove that this was the configuration that my car was build to by British Vita and it won the STCC in 1972.. so I guess it didn't perform that badly. It also ran against some of the 'greats' at Brands Hatch and finished top 3.
    ......I'm simply trying to get background on the setup. And yes, the bottom Links we added later in the development of the car in 1972.

    Re: 4 link MK1 with inboard turrets SATCHEL LINK

    Do the they look parallel, or does your quote say there are parallel?

    There's also a picture of FEV1H axle on the www that shows same top link, and all the world cup cars were built the same.

    I was looking for input and information on the world cup setup, and if you consider 'World cup'

    FEV 1H
    FEV 2H
    FEV 3H
    FEV 4H
    FTW 46H
    FTW 47H
    FTW 48H


    cars as 'works car' then your quote "Works cars started with short parallel radius links" is incorrect

    Re: 4 link MK1 with inboard turrets SATCHEL LINK

    I acknowledge that the 'World Cup' Cars where 'odd balls' in terms of suspension - none of the 'rally' works cars used anything like this and as said the the quote above 'was more for keeping the axle in place than for any performance advantage. However the works rally cars did feature short parallel radius arms together with a transverse horizontal link for lateral location, all from day 1 of the Ford Rally program. My issue is with your diagram - different attachment points for the arms will lead to different geometry changes with end trying to rip themselves out of the chassis attachments as they are swinging through different arcs - the set up only works with a single pair of radius arms.

    The image was grabbed from the www and while it does not accurately reflect the my setup of the angled top bars are correct. My car used coil-over and and was told it also used dummy leaf springs due to race regulations. I have since found out the dummy leaf springs were possibly plastic/fiberglass, slipper springs for location.
    FYI, My car has the lower mounting points at the same lateral length along the chassis of the car.
