Description

Technical Field

[0001] The present invention relates to the field of connecting mechanisms and bogies, and in particular to an articulated joint mechanism and a bogie capable of releasing a vehicle nodding motion. Background Art

[0002] Modern urban transportation systems are mainly composed of subways, trams, buses, etc. Although subways have strong transportation capacity, their huge costs make them not widely used in small and medium-sized cities; trams require special power systems and track designs, and both the design and construction costs and maintenance costs are relatively high, and are easily restricted by the traditional operating environment; buses are restricted by their transportation capacity and cannot meet the needs of urban transportation during peak hours in the morning and evening; the emergence of low-floor trackless vehicles can better alleviate this embarrassing situation. Low-floor trackless vehicles have the advantages of large vehicle marshaling capacity and low platforms for easy boarding and alighting, making them play an increasingly important role in urban transportation.

[0003] The bogie is the most important structural component of low-floor trackless vehicles. Its structure and various directional parameters directly determine the vehicle's operational stability and ride comfort. The axle bridge at one end of the bogie connects to the front vehicle body, and the other end to the rear vehicle body. The two axles are connected by an articulated mechanism, thus connecting the two vehicle bodies. However, existing articulated structures are rigid connections that prevent the vehicle from nodding, thus reducing ride comfort.
