Abstract

The invention relates to a hydraulic buffer device for realizing safety turn of a hinged vehicle based on a hinged system. The hydraulic buffer device comprises a basic damping oil line and a pressurizing control oil line, wherein the basic damping oil line and the pressurizing control oil line are connected in parallel to form a hinged damping pressure control oil line, an oil return line is arranged between the hinged damping pressure control oil line and an oil storage tank, a second oil absorbing line is arranged between the oil storage tank and a rod cavity, a safety locking oil line is arranged between the rod cavity and the oil return line, and a reversing assembly is arranged in a second oil pressure line. The invention also provides a method for realizing the safety turn of the hinged vehicle by using the hydraulic buffer device. The hydraulic buffer device and the method based on the hinged system for realizing safety turn of the hinged vehicle have the advantages that the vehicle can be easily and quickly turned, so the dragging of the vehicle and the tail throwing of the vehicle after straightening during turning are avoided; meanwhile, when the accident of the vehicle occurs, the shape of the vehicle during accident occurrence is maintained, the larger hazard is avoided, and the application range is wider.

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...
