Unbalanced Road Wheel

[718as]

Hello,

I was wondering can you still feel a vibration in an electric steering wheel if a road wheel is unbalanced?

Thanks

Yep, Unbalanced wheel, buckled rim or an out of round tyre can all cause vibration issues - Normally at specific speed ranges, 50 - 70 for an unbalanced tyre seems to be the norm.

As above yes you can.

Further, many people seem to be under the impression that an ‘electric’ steering system is some sort of drive by wire type affair (not saying this is you),  it isn’t; there is still a direct physical connection from steering wheel via steering column/rack etc to the wheels. It is only the assistance that is provided electrically.

Pushes up to the high 70s or low 80s on bigger rims 17" upwards.  The bigger the rim the higher speed the vibration will build from. and as @Greenman says there is still a mechanical link it is only electric assistance instead of the 'old fashioned' (but slightly less power efficient on the engine and hence emmissons...) better feeling hydraulic assistance.

Thanks, yes there needs to still be a physical connection, can u imagine if there wasn't and an electric fault occured. 😮

Planes are fly by wire...

.....but with multiple redundant systems to run it; Just starting with two sticks! Imagine the weight penalty of having 3 primary and three secondary steering ECUs plus two separate rack drive systems with redundancy on both.

As well as the redundant systems, Boeing & Airbus have a separate mechanical or electrical backup on most aircraft for pitch & yaw so not totally dependant on fly by wire.
