Abstract
A triple axle suspension for use in a vehicle having a front axle, a medium axle and a rear axle mounted in triple axle relationship. It makes use of rigid beams to support the axles. It also makes use of equalizers to interconnect the beams, and it is devised in such a manner that one end of each beam is free to slide within the adjacent supporting structure. This suspension is very simple in structure and very efficient to equalize the load of any axle over all the axles of the triple axle suspension. When the axles are motorized, the suspension is also efficient to balance the pulls exerted by the wheels supported by the axles.
