Abstract

The invention relates to a three-degree-of-freedom articulated structure of an articulated tracked vehicle and belongs to articulated mechanisms of tracked vehicles. A rear vehicle support assembly is fixedly connected with a middle connecting rack. The middle connecting rack is articulated to a front vehicle support through a first pin. One end of a pitching oil cylinder assembly is articulated to the rear vehicle support assembly. The other end of the pitching oil cylinder assembly is articulated to a front vehicle upper support and the front vehicle support. A front vehicle lower support is articulated to the lower portions of the front vehicle support through second pins. A left steering oil cylinder assembly and a right steering oil cylinder assembly are articulated to the two sides of the front vehicle support corresponding. The three-degree-of-freedom articulated structure has the advantages of being novel, advanced in design concept, easy to machine and manufacture and convenient to maintain, and facilitating laying of oil cylinder pipes. Through the structure, front and back vehicle body steering, pitching and twisting motion of a vehicle can be realized, and the passing capacity and the off-road performance of the vehicle are greatly enhanced.

Description

technical field [0001] The invention belongs to a hinge mechanism of a crawler vehicle, which is applied to a double-joint crawler vehicle and connects the front and rear car bodies of the articulated crawler vehicle to realize the relative steering, pitching and horizontal torsion movements of the two car bodies. Background technique [0002] The biggest feature of the articulated tracked vehicle using the three-degree-of-freedom hinge mechanism is that it can walk on various complex road surfaces. The front and rear car bodies are connected by the hinge mechanism, so that the front and rear car bodies can realize relative steering, pitching and torsional movements. Its steering and pitching movements are controllable, and the two car bodies can make corresponding adjustments as the terrain changes, so that the limited track length can keep in contact with the ground as much as possible, thereby obtaining a high passing capacity. Therefore, the tracked vehicle using this ar...
