Description

一种轨道车辆车头结构Rail vehicle head structure 技术领域Technical field
本发明涉及一种轨道车辆车头结构,属于轨道交通车辆车体结构技术领域。The invention relates to a rail vehicle head structure, and belongs to the technical field of rail vehicle body structure.
背景技术Background technique
目前地铁车辆车体主要有两种:一种含铆接(或螺栓连接)的结构,如中国专利申请号为CN200620069988.8及CN201310072635.8描述的结构,其主要特点是司机室骨架甚至车头底架前端是独立模块,通过螺栓或铆钉连接到车体主结构上,底架边梁一般不会延伸到司机室门区域;另一种是全焊接结构,其主要特点是作为车体主要承力部件的底架边梁是通长的,即从客室区域延伸到司机室门区域前方。前者车头前端可设计为独立的司机室骨架和玻璃钢头罩,头型变化多,但铆接结构车体有重量较重、全寿命周期内密封性不良、且车辆运行长期振动易导致铆钉松动等问题。后者全焊接结构基本不会产生上述问题,但司机室骨架结构也是集成到车体主结构上,易导致造型受限,难以满足追求现代气息、体现城市个性风格的需求。At present, there are two main types of subway vehicle bodies: a structure including riveted (or bolted) structures, such as those described in Chinese Patent Application No. CN200620069988.8 and CN201310072635.8, the main features of which are the cab skeleton or even the undercarriage. The front end is a separate module that is connected to the main structure of the vehicle body by bolts or rivets. The side frame side beams generally do not extend to the driver's cab door area; the other is an all-welded structure, which is mainly used as the main bearing part of the vehicle body. The underframe side rails are long, extending from the passenger compartment area to the front of the cab door area. The front end of the former can be designed as an independent cab skeleton and a fiberglass hood. The head shape varies greatly, but the riveted structure body has heavy weight, poor sealing performance during the whole life cycle, and long-term vibration of the vehicle is easy to cause loose rivets. . The latter all-welded structure basically does not cause the above problems, but the skeleton structure of the driver's cab is also integrated into the main structure of the car body, which is easy to cause limited shape, and it is difficult to meet the demand for pursuing modern atmosphere and reflecting the urban individual style.
同时,国内部分城市开通地铁已几十年,部分线路已到达更新换代的过渡阶段,20多年前车辆碰撞性能没有现在要求高,部分车辆的防爬器是不具吸能功能的,安装位置也更接近车体地板面,高度较高。此外,很多城市的地铁线路正面临扩建和列车增购的需求,而不同车辆厂家造的列车防爬器高度不完全一致。因此在既有线路上的新造列车,首先要解决防爬器匹配的问题,而防爬器吸能要求也越来越高,提高了防爬器选型的难度,对车辆外观 设计提出了进一步限制。At the same time, some cities in China have opened subways for decades, and some routes have reached the transitional stage of replacement. More than 20 years ago, the collision performance of vehicles was not as high as required now. Some vehicles' anti-climbing devices have no energy-absorbing function, and the installation position is also more. Close to the floor of the car body, the height is high. In addition, subway lines in many cities are facing the need for expansion and train purchases, and the heights of train anti-climbing devices made by different vehicle manufacturers are not completely consistent. Therefore, in the new trains on the existing roads, the problem of matching the anti-climbing devices must be solved first, and the anti-climbing device has higher and higher energy requirements, which improves the difficulty of selecting the anti-climbing device and the appearance of the vehicle. The design proposes further restrictions.
目前国内全焊接结构的A型车地铁车一般采用压溃式防爬器,其安装结构与中国专利申请号为CN201310505736.X的发明专利描述的结构类似,该结构的防爬器安装板直接和底架边梁相连,防爬器工作时将承受巨大的纵向力和垂向力,通过将力直接传递给底架边梁从而获得了良好的耐碰撞性能。但是这种类型防爬器是通过十字形导槽来导向,由于强度需要和结构特点要求防爬器尺寸较大,离车体地板面也需保持一定距离,同时要求与防爬器安装板连接处的底架边梁的强度足够强。这些因素产生了以下问题:At present, the A-type subway car of the all-welded structure in China generally adopts a crush-type anti-climbing device, and its installation structure is similar to the structure described in the invention patent of Chinese Patent Application No. CN201310505736.X, and the anti-climbing installation plate of the structure is directly The side frame side beams are connected, and the anti-climbing device will bear huge longitudinal force and vertical force when working, and good collision resistance is obtained by transmitting the force directly to the underframe side beam. However, this type of anti-climbing device is guided by a cross-shaped guide groove. Due to the strength requirement and structural characteristics, the anti-climbing device is required to have a large size, and a certain distance from the car body floor surface is required, and the anti-climbing device mounting plate is required to be connected. The strength of the underframe side beam is strong enough. These factors have the following problems:
1)防爬器距轨面高度调节范围受到了限制,降低了与既有线路车辆防爬器啮合匹配程度,难以满足EN 15227标准规定爬车要求;1) The range of height adjustment of the anti-climbing device from the rail surface is limited, which reduces the matching degree with the anti-climbing device of the existing line vehicle, and it is difficult to meet the climbing requirements of the EN 15227 standard;
2)底架边梁需延伸出防爬器安装板较长的距离,导致头罩的圆弧拐点前移,头罩的圆弧段长度和形状受限,对造型设计极其不利,易造成各种车型的外观造型缺乏变化的感觉。2) The side frame side beam needs to extend a long distance from the anti-climbing device mounting plate, which causes the arc inflection point of the hood to move forward. The length and shape of the arc segment of the hood are limited, which is extremely unfavorable for the design and easy to cause The appearance of the model lacks a sense of change.
