Articulated system of articulated vehicle chassis

Abstract

The invention relates to an articulated system of an articulated vehicle chassis. The articulated system of the invention comprises a front truss, a rear truss, a rotating disk bearing, a crossbeam, and two symmetrically arranged hydraulic buffer units, wherein the rotating disk bearing consists of an outer ring and an inner ring; the rear truss is fixedly connected with the inner ring; and the front truss is fixedly connected with the outer ring via the crossbeam. The rear truss comprises a left side arm, a right side arm, a first rear beam, and a second rear beam, wherein the first rear beam and the second rear beam are arranged relatively vertical to the left side arm and the right side arm. One end of each hydraulic buffer unit is connected with the crossbeam, with the other end beingconnected with the first rear beam arranged on the rear truss. According to the invention, the joint strength of the articulated system is improved by adopting a double-rear-beam structure and the driving security of vehicle is enhanced via hydraulic latching and mechanical latching.

Description

technical field [0001] The invention relates to the technical field of vehicle chassis articulation, in particular to an articulating vehicle chassis articulation 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. An articulated bus generally consists of front and rear compartments and a chassis hinge system connecting the front and rear compartments. The chassis hinge system includes a turntable bearing, a front truss, a rear truss, and a damping system. The turntable bearing includes an outer ring and an inner ring, as disclosed in Chinese patent CN201086609 A large articulated passenger car chassis hinge system, the front truss is fixedly connected to the outer ring of the ...

Problems solved by technology

An articulated bus generally consists of front and rear compartments and a chassis hinge system connecting the front and rear compartments. The chassis hinge system includes a turntable bearing, a front truss, a rear truss, and a damping system. The turntable bearing includes an outer ring and an inner ring, as disclosed in Chinese patent CN201086609 A large articulated passenger car chassis hinge system, the front truss is fixedly connected to the outer ring of the turntable bearing through the beam, and the rear truss is fixedly connected to the inner ring of the turntable bearing. There are many, the structure is more complicated, and it takes up a lot of space. Occasionally, there will be oil leakage at the hydraulic components and pipeline joints, which not only affects the performance of the vehicle, but also causes the vehicle to fail to run when it is serious; in addition, the structure only has hydraulic locking. There is no mechanical limit lock. If the turning angle is too large and too sharp, the front and rear compartments will "fold" when the hydraulic lock fails, which will damage the hinge system components and cause property damage and casualties in severe cases.
