Abstract:
A four module trolley bus and a steering control articulation system thereof, comprising a controllable articulation mechanism connected between a first carriage (1) and a second carriage (2) and between a third carriage (3) and a fourth carriage (4), and a follower articulation mechanism connected between the second carriage (2) and the third carriage (3); the controllable articulation mechanisms are used for controlling the second carriage (2) to implement corresponding steering on the basis of the real-time movement direction angle between the first carriage (1) and the second carriage (2) and controlling the third carriage (3) to implement corresponding steering on the basis of the real-time movement direction angle between the third carriage (3) and the fourth carriage (4); and the follower articulation mechanism is used for rotatably connecting the second carriage (2) and the third carriage (3). The present steering control articulation system of a four module trolley bus can improve the steering precision of each carriage of a multi-module trolley bus, eliminating steering deviation due to the steering lag of the rear carriages.
