ARTICULATED SYSTEM-BASED HYDRAULIC BUFFER FOR REALIZING SAFE TURN-BACK OF VEHICLE, AND METHOD THEREFOR

摘要

The invention relates to a hydraulic buffer that can enable the articulated vehicle to gyre safely based on the articulated system, comprising the basic damping oil circuit and boost control oil circuit, which are connected in parallel, forming articulated damping pressure control oil circuit; an oil return circuit is arranged between the articulated damping pressure control oil circuit and the oil storage tank; the second oil absorption circuit is arranged between the oil storage tank and the rod port; the oil circuit for safe lock-up is arranged between the rod port and the oil return circuit; the reversing assembly is arranged in the second oil pressing circuit; besides, the invention further provides a method that can enable the articulated vehicle to gyre safely through the above hydraulic buffer; by adopting the hydraulic buffer that can enable a vehicle to gyre safely based on the articulated system as well as its method, the vehicle can gyre lightly and quickly, is avoided from towing during the gyration and drifting after being set right; meanwhile, when the vehicle suffers an accident, the vehicle can maintain the shape of accident, avoiding greater damage, with wider range of application.
