The present application relates to the technical field of vehicles, in particular to a load wheel chain assembly, comprising a load wheel and a load wheel suspension, the load wheel is installed on the load wheel suspension, the load wheel suspension is sequentially connected in series, forming a flexible load wheel chain assembly. The load wheel chain assembly can be used as a load wheel and a supporting belt wheel, and can guide the rubber track by limiting the lateral displacement (along the width direction of the track) of the rubber track, thereby avoiding the occurrence of the off-track condition. The flexible form of the load wheel chain assembly can make the ground contacting part of the walking system better adapt to the change of the terrain, and facilitate the adjustment of the ground contacting area of the walking system.
