Default Inward Camber for rear wheels of 3 wheelers

Hi All

Many a times I have observed that the rear wheels of a goods-carrying 3 wheelers (like Piaggio Ape and 3 wheelers from Mahindra & Bajaj) have an inward camber. Any particular reason why?

You must've seen this in Ape three wheelers.

When the vehicle is fully loaded the rear wheels will become true to the ground with a parallel contact patch. With zero or near zero camber.

If the wheels didn't have any camber then once the vehicle is loaded the wheels would have a negative camber. Which is not good for the life of the tyre especially when it is loaded.

Since these vehicles are designed to run with load most of the time their suspension is setup to offer maximum benefits in that scenario.

Actually, these vehicles are most times over-loaded. The manufactureres too would have taken note of how these would be used and provided a suitably over-compensated camber setting. This way, the vehicle is ready for over-loading, thus reducing break-down of the rear suspension. And the vehicle owners are happy too !

sic.

Its not that there is any high tech something in them, its just that these employ swing arm axles.
