ABSTRACT:
An articulated toy vehicle capable of negotiating a difficult terrain such as a terrain characterized by successive troughs and peaks and other irregularities. The articulated vehicle is composed of a wheeled tractor section and a series of wheeled trailer sections linked thereto by means of a motor-driven, multi-section drive shaft, each section of which is operatively coupled to a wheel axle of a respective vehicle section. The drive shaft sections are intercoupled by detachable universal joints whereby as the vehicle traverses the difficult terrain, it assumes a sinuous formation conforming to the varying contours of the terrain to provide a distributed traction making it possible for the vehicle to overcome the difficulties presented by the terrain.
