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.
