During fierce braking on a rough road surface, the
leaf spring and the spring bracket have to deal
with the forces of the weight of the vehicle (which
is increased by driving over holes) and with the
braking forces at the same time. This results in a
considerable total force exerted on the leaf spring
and the spring bracket.
Spring opening
The spring opening (P in the drawing) indicates
the deflection of the spring.
The spring assembly is constructed to obtain the
optimum spring opening for a laden vehicle. If
possible, check the spring opening on both sides
of an evenly laden vehicle.
As a result of tolerances in the manufacturing
process, it is possible that the spring openings
differ from each other when the springs are
unloaded, but are equal when the springs are
loaded.
When spring assemblies are new, the difference
in spring opening is small. As a result of settling
of the spring assembly, the difference in spring
opening may increase.
When the springs are loaded they become longer
and the axle will move backwards. If the left and
right spring openings of one axle differ too much,
the result will be misalignment of both the vehicle
and the axle.

2.4 OVERVIEW DRAWING, TANDEM AXLE SUSPENSION
Note:
The tandem axle suspension may have a
trapezoidal or parabolic leaf spring assembly.
The trapezoidal leaf spring assembly is shown in
the drawing. Neither an arresting cable nor an
alignment plate is used for the parabolic leaf
spring assembly.
