Roll Steer | How roll steer can be corrected ? | What is roll center and Roll axis | Anti-Roll Bar

Roll steer is the undesirable changes in steering angle of steered wheels during the rolling action of vehicle body at time of fast cornering or Road irregularities. Roll steer is the error caused due to improper length ,angle of tie rod and due to bad suspension geometry.
In this video you will learn :-
1) What is roll steer ?
2) How roll steer can be corrected ?
3) What is Roll center & Roll axis ?
4) What is Anti-Roll bar and how it prevents vehicle body from Roll ?

Great explanation

[@adamdrives365]

Great explanation thank you

great explanation !!

Thank you

Can You please talk about how to Draw the Roll-Axis for a 3 Wheeled Vehicle with 1 wheel in the rear. Thanks

[@RajendraYadav-bh3nk]

Very informative video sir..

[@thevatsaljain]

Thank you !

[@omaralwahban1771]

very good video! good job bai

[@thevatsaljain]

Thanks

[@RajendraYadav-bh3nk]

Sir.. please make a separate video on anti dive and anti squat.. Also on important point to keep in mind while designing the geometry of double wishbones and semi trailing arm for Baja vehicles.

[@thevatsaljain]

Soon will be uploading video on Anti dive and Anti squat geometry.

@@thevatsaljain Thank you sir

[@sachindethe3023]

thanks for sharing , it's would be very useful for Passenger vehicle . How does it applicable commercial vehicle where solid axle, leaf springs and Pittman arm drag link type steering system is used ? Could you please make some video on this as well it would be useful 😊

[@thevatsaljain]

You're welcome! Roll center more depends on the type of Suspension geometry as compared to type of Steering geometry. The rules are same for all the suspension geometries. You just have to find the instantaneous center of suspension linkages and you are good to go! Still stay tuned soon , i will be covering all the types of suspension geometries and i am sure that will clear all your doubts.

Hi, if the roll center was aligned with the gravity center of the car (y=0) would you still need an anti roll bar? Thanks and superb content!

[@sreehariraju5704]

Aligning roll center with center of gravity will cause jacking force to act. It should not be done

hi could you please do a diagram of how to set up handle bar steering via shaft to two front wheels ..does the length of arm that is attached to kin pin make any difference to roll steer ..ive built reverse harley trike so one back wheel two front..i have set ic but trike seems to wallow am i missing something ..im using trailing arms and have fitted sway bar..send email and ill send pic if you can help be very grateful

[@thevatsaljain]

You can send your queries at :- [e-mail]

[@mikemills9279]

sorted thanks all down to instant centre configuration..tirke handles well now

[@wtacademy5091]

@@mikemills9279 How did you resolved it?, i had the same doubt when i watched the video, thanks!.

Nice job bro you are doing well you are engineering student if yes which college

Thank you ! Yes ,from MNIT Jaipur.
