Spherical hinge structure in chassis articulated system of articulated vehicle

Abstract

The invention relates to a spherical hinge structure in a chassis articulated system of an articulated vehicle, which belongs to the field of chassis articulated systems of articulated vehicles. The spherical hinge structure comprises a metal core, an elastic component and a support chip, wherein the elastic component is arranged on the outside surface of the middle part of the metal core, the support chip is arranged at the outside of the elastic component, the metal core comprises a main shaft and at least a boss, and the boss is arranged on the outside surface of the main shaft of the metal core. The spherical hinge structure provided by the invention is clever in design, has high joint strength and long service time, and can effectively prevent a central shaft of the spherical hinge from moving leftwards and rightwards in the elastic component; meanwhile, a cushioning effect on external forces can be generated through the arrangement of a cushion hole.

Description

technical field [0001] The invention relates to the technical field of an articulated bus chassis hinge system, in particular to a ball joint structure in an articulated bus chassis hinge system. Background technique [0002] With the rapid development of my country's automobile manufacturing industry, various vehicle manufacturing industries are also advancing by leaps and bounds. Articulated buses are gradually popularized in large and medium-sized cities in China due to their large passenger capacity and high utilization coefficient. [0003] Articulated buses are generally composed of front and rear compartments and a chassis hinge system connecting the front and rear compartments. The chassis hinge system includes turntable bearings, front frames, rear frames, and damping systems. The front frame is fixedly connected to the outer ring of the turntable bearing through a beam, and the rear frame It is fixedly connected with the inner ring of the slewing bearing, and the f...

[0003] Articulated buses are generally composed of front and rear compartments and a chassis hinge system connecting the front and rear compartments. The chassis hinge system includes turntable bearings, front frames, rear frames, and damping systems. The front frame is fixedly connected to the outer ring of the turntable bearing through a beam, and the rear frame It is fixedly connected with the inner ring of the slewing bearing, and the front frame is generally connected with the beam through a spherical joint connection mechanism such as a ball joint and a ball joint holder. The ball joint is generally composed of a metal core and an elastic element. A ball hinge connection structure in the chassis hinge system of a large-scale articulated bus, which discloses a ball hinge hook, which only pours rubber outside the middle part of the rigid central axis. During the turning process, the force on the central axis of the ball joint is relatively large, and it is easy to cause the central shaft of the ball joint to move left and right in the elastic element, which affects the stability of the articulated vehicle during operation. At the same time, due to the large force, the ball joint is easily damaged
