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.
