Trailer for transporting freight containers and method of use

摘要

A suspension assembly for securing a wheel to opposed sides of a container carrying frame. A pivoted wheel support arm is secured at a forward pivot end to a pivot pin retained in the frame. A wheel axle assembly is secured at the rear free end of the pivot arm and adapted to connect a wheel thereto and has a shock absorber connecting bracket. A shock absorber connecting member extends above the pivot pin and is pivotally displaceable in facial alignment with a stationary shock absorber connector secured to the frame. A shock absorber is retained captive between the shock absorber connecting member and the stationary shock absorber connector to absorb vertical displacement loads transmitted to the pivotal wheel support arm.

1. A wheel supporting suspension assembly for securing at least a wheel to a side of a frame, said suspension comprising a pivoted wheel support arm secured at a forward pivot end to a pivot pin retained in a frame attachment member for pivotal connection of said pivoted wheel support arm to said frame, a wheel axle assembly secured at a rear free end of said pivoted wheel support arm and adapted to connect the wheel thereto, a shock absorber connecting bracket secured to said forward pivot end of said pivoted wheel support arm and having a shock absorber connecting member extending above said pivot pin, said shock absorber connecting member being pivotally displaceable in facial alignment with a stationary shock absorber connector secured to said frame, a shock absorber retained captive between said shock absorber connecting member and said stationary shock absorber connector and compressible therebetween by said shock absorber connecting member being displaced toward said stationary shock absorber connector by upward movement of said pivoted wheel support arm to absorb vertical displacement loads transmitted to said pivoted wheel support arm by the wheel connected thereto, a vertical lateral displacement stabilizing plate having a first end secured to said rear free end of said pivoted wheel support arm and a second end free, the vertical lateral displacement stabilizing plate extending vertically above said pivoted wheel support arm, said vertical lateral displacement stabilizing plate having a flat friction surface displaceable against a flat outboard vertical side wall of said frame to prevent lateral displacement of said pivoted wheel support arm when displaced on said pivot pin.
