Car body articulation device and rotation angle control method for self-guiding virtual track train

Abstract

The invention discloses a vehicle body hinged device and a rotation angle control method for a self-guided virtual track train. The vehicle body hinged device comprises hinged mounting seats, a spherical metal joint and an angle sensor assembly. The hinged mounting seats are hinged by the spherical metal joint, and the angle sensor assembly is installed on the hinged mounting seats. The angle sensor assembly comprises an angle sensor, a sensor limiting bracket and a sensor positioning bracket. When a vehicle crosses a curve virtual track, the rotation angle of the hinged device is measured bythe angle sensor, and the angle information is fed back to a control system. The control system adjusts the rotation angle of the hinged device by an active shock absorber according to the angle information. According to the vehicle body hinged device and the rotation angle control method for the self-guided virtual track train, the displacement, in the longitudinal, lateral and vertical directions, of a vehicle body is limited, three-way rotation between the two vehicle bodies is allowed, and the function of load transmission is achieved. After the vehicle separation distance is reduced, andthe length of a penetrating channel is shorted, the utilization rate of vehicle space can be improved, and at the same time the turning radius of the vehicle can be smaller.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles. Background technique [0002] At present, the articulated car body connection structure of virtual rail trains mostly adopts the articulated structure in which the front end and the rear frame are respectively fixedly connected with the turntable ball bearings and at least one end is fixed on the car body through a rubber ball hinge. The main problems are the length of the through channel and the large size of the hinged device. And because the tires are arranged near the middle of the car body, the space available for the tire protrusions and the aisle of the passage is reduced, and the space utilization rate of the vehicle is low. The articulation device of the virtual rail train not only needs to meet the connection and bearing functions, but also requires the horizontal angle detection and feedback function to adjust the parameters of the curved road. At present, this kind of a...

The two inventions with application numbers CN201610384861.3 and CN201610384861.3 mainly disclose a car body articulation scheme for low-floor trams in which the upper and lower mounting seats are connected by ball metal joints through bolts. Gauge low-floor vehicles, but the allowable minimum horizontal curve and vertical curve road radius is relatively large, accounting for more urban public resources, and at the same time, the structure has a single function, which cannot meet the functions of self-guiding and angle measurement
