Steering angle sensing device in chassis articulated system of articulator

Abstract

The invention relates to a steering angle sensing device in a chassis articulated system of an articulator, comprising a front frame, a rear frame and a turntable bearing, wherein the turntable bearing comprises an inner ring and an outer ring; the front frame is fixedly connected to the outer ring of the turntable bearing; the rear frame is fixedly connected to the inner ring of the turntable bearing; the inner ring and the outer ring can rotate relatively; the steering angle sensing device in a chassis articulated system of an articulator further comprises an angle sensor, a first angle sensor and a second angle sensor, wherein the angle sensor is fixedly arranged on the inner ring of the turntable bearing; the first angle inductor and the second angle inductor are fixedly arranged on the front frame; the device related by the invention can sense steering angles, achieve the effects of intelligently strengthening damping, angle exceeding alarm and hydraulic locking, and prevent 'cutting' accidents.

Description

technical field [0001] The invention relates to the technical field of an articulated bus chassis hinge system, in particular to a steering angle sensing device 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 turntable bearing...

AI Technical Summary

Problems solved by technology

[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 turntable bearing, and the rotation of the front and rear frames can realize the free steering of the articulated vehicle. The steering of the articulated vehicle does not require very high width of the road, which is a major advantage of the urban articulated bus, but if the turning angle is too large (Especially for articulated buses with rear engines), the lateral force generated by the rear compartment on the front compartment will increase, causing serious sideslips, known in the industry as "shearing" accidents between the front and rear compartments of articulated vehicles, resulting in property damage and casualties ACCIDENT
