Abstract

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.

Description

technical field [0001] The invention relates to the technical field of articulated passenger cars, in particular to a hydraulic buffer and a method thereof for realizing safe turning of vehicles based on an articulated system. Background technique [0002] Articulated vehicles are generally composed of two compartments, the front compartment and the rear compartment are connected by a chassis hinge system, the chassis hinge system includes a front frame, a rear frame, a turntable bearing and a hydraulic buffer that provides damping, and the front frame is fixedly connected to the front compartment through a front beam , the rear frame is fixedly connected to the rear compartment through the rear beam, and the left and right pieces of the hydraulic buffer are connected between the front frame and the rear frame of the hinge system. The rear frame rotates relatively, and the proximity switch can be triggered during the rotation process, which is connected between the front fra...
