i would say that a heavy load on a spring, when going over a
bump, compresses the spring down to dampen the effect of the shock,
as compared to a light weight over a spring. beacuse in some cases,
(eg the KUB), the air bag has a certain pressure to it, and only
beyond a certain weight, will the effect of going over a hump
compress the spring. before this weight is reached, what will
happen is that the axle goes over the bump, pushing the spring up
aginst the bus. but as the specific weight has not been reached,
there is minimal compression of the spring, and someitmes, like an
empty truck with leaf spring suspensions, the vehicle body goes up
along with the axle and the suspension.
Yup yup.
That's what I meant.
Simply speaking you should expect a heavier load on the spring
to cause the spring to work better.
But you cannot put a load so heavy that the spring deforms
(Hooke's Law). Spring in this case refers to any means to dampen
shocks and vibrations transmitted from the wheels to the body.
And I cannot resist but add that Hooke's law states that the
extension/compression of a spring system is directly proportional
to the force exerted on the system up to a certain limit. No
offense, ZYX, but your explaination using Hooke's law left me
