数字轨道胶轮电车（DRT）是一种自主研制的中低运量轨道交通新制式。该电车在传统有轨电车和大巴车的基础上，集合各自优点，为城市交通运输提供全新的解决方案，DRT车辆最高运行速度70km/h，采用橡胶车轮、公路形式、电子导向、车载储能等先进技术，具有道路适应性强、智能化、绿色环保、低成本运营、轻量化（轴重7t）、大运量、安全及充分冗余等特点。The Digital Rail Rubber-Tyred Tram (DRT) is a new type of rail transit independently developed for medium and low capacity. Based on the traditional tram and bus, the tram combines the advantages of each to provide a new solution for urban transportation. The DRT vehicle has a maximum operating speed of 70km/h, and adopts advanced technologies such as rubber wheels, road form, electronic guidance, and on-board energy storage. It has the characteristics of strong road adaptability, intelligence, green environmental protection, low-cost operation, lightweight (axle weight 7t), large capacity, safety and full redundancy.
动拖车转向架作为该制式车辆的重要走行部分，连挂MC车与T车，其结构是否合理、性能好坏直接影响到车辆转向、运行平稳性、安全性及舒适性。 而现有的转向架因未安装二系垂向油压减振器，存在车辆平稳性较差的问题，造成车辆舒适性不高，严重影响乘客乘车体验。且车辆铰接盘自由度不高，铰接受力状况恶劣，考虑到车辆为公路行驶，行车状况不佳，会造成车辆寿命下降。As an important running part of the standard vehicle, the trailer bogie is connected to the MC car and the T car. Whether its structure is reasonable and its performance is good or bad directly affects the vehicle's steering, running stability, safety and comfort. However, the existing bogie has poor vehicle stability because it is not equipped with a secondary vertical hydraulic shock absorber, resulting in low vehicle comfort and seriously affecting the passenger riding experience. In addition, the vehicle's articulation plate has a low degree of freedom and the articulation stress condition is poor. Considering that the vehicle is traveling on the road, the driving condition is poor, which will cause the vehicle life to decrease.
