Primary conical spring

The primary conical spring is an easily fitted and compact suspension unit in which the rubber is loaded in combined shear and compression. Optimum load-deflection properties, i.e. high load capacity and large static deflections can be provided within acceptable space envelope limitations.

 

The range illustrated below caters for static vertical loads and deflections up to 50kN and 40mm respectively, which are typically suitable for many primary suspension requirements. These springs may also be considered for secondary suspensions and power unit applications.  Conical springs generally provide the same stiffness rates in the principal horizontal modes but alternative designs with dissimilar horizontal stiffness rates can be produced.
