Abstract
A railgear guide unit assembly for a road vehicle comprises a pair of rail wheels coupled to an axle, a first pair of pivotal links, and a second pair of pivotal links, wherein both pairs of pivotal links are coupled to the axle at one end. The assembly further comprises a pair of railgear pressure mechanisms, wherein the railgear pressure mechanisms each comprise an outer guide assembly, an inner guide translatable within the outer guide assembly, and a spring coupled to a first end of the inner guide to provide a compressive force on the inner guide. One end of each of the pair of pivotal links is coupled to a respective inner guide such that a movement of the inner guides of respective railgear pressure mechanisms corresponds to a movement of the respective pair of pivotal links.
