Abstract

An articulated bogie for a low-floor straddle-type monorail, comprising: a framework, a locomotion wheel assembly, a horizontal wheel assembly, foundation brakes, driving units, air springs, a traction articulation mechanism, traction rubber piles, shock absorbers, and the like. The articulated bogie is a two-axle bogie; the upper portion of the traction articulation mechanism is connected to two compartments respectively, achieving motion decoupling of adjacent compartments; and the lower portion of the traction articulation mechanism is connected to the traction center of the bogie to transfer loads such as traction force and braking force. The driving units are arranged in a tire assembly and are each integrated with a gear box and a motor; an interface is reserved at the gear box end to mount a locomotion tire assembly; and the motor end is directly and firmly connected to the framework. The bogie only occupies the upper space on a single side, thereby achieving the low-floor design of vehicles. The articulated bogie for a low-floor straddle-type monorail has a simple and compact structure, facilitates full utilization of the space at the ends of vehicles, reduces the number of horizontal wheel assemblies, and improves the utilization efficiency of parts of bogies.

Description

一种低地板面跨座式单轨铰接转向架A low-floor straddle-type monorail articulated bogie 技术领域Technical Field

本专利涉及一种低地板面跨座式单轨铰接转向架，属于转向架技术领域。This patent relates to a low-floor straddle-type monorail articulated bogie, which belongs to the technical field of bogies.

背景技术Background Art

跨座式单轨作为一种轨道交通制式，在轨道交通领域有着广泛的应用。现有跨座式单轨主要包括：双轴转向架配合高地板面及单轴转向架配合低地板面两种形式。相比高地板面形式，现有单轴转向架低地板面形式垂向空间利用率高。尤其是对隧道的垂向空间需求小，可以减小线路施工量。As a rail transit system, straddle-type monorail is widely used in the field of rail transit. Existing straddle-type monorail mainly includes two types: double-axle bogie with high floor and single-axle bogie with low floor. Compared with the high floor type, the existing single-axle bogie low floor type has a high vertical space utilization rate. In particular, it has a small vertical space requirement for tunnels, which can reduce the amount of line construction.

单轴转向架配合低地板形式有一个特征：客室内需要设置轮仓，以包覆轮胎超过地板面的区域。减小轮仓占用对增大客室有效利用空间有显著影响。The single-axle bogie with low floor has a characteristic: a wheel well needs to be set up in the passenger compartment to cover the area where the tire exceeds the floor surface. Reducing the occupancy of the wheel well has a significant impact on increasing the effective use of space in the passenger compartment.

转向架铰接结构、水平轮布置方式及构架结构设计是该铰接转向架设计的关键技术。目前，用于低地板跨座式单轨的铰接转向架处于研究阶段，尚无成熟应用。如何充分发挥低地板面、铰接结构的优势实现转向架设计，成为本领域技术人员亟待解决的重要技术问题。The bogie articulation structure, horizontal wheel arrangement and frame structure design are the key technologies in the design of the articulated bogie. At present, the articulated bogie for low-floor straddle monorail is in the research stage and has not yet been maturely applied. How to give full play to the advantages of low floor and articulated structure to realize bogie design has become an important technical problem that needs to be solved urgently by technicians in this field.

经检索发现CN110182240A公开了跨座式单轨车辆车体与转向架连接结构及跨座式单轨车辆，跨座式单轨车辆车体与转向架连接结构包括依次设置的第一车体、转向架总成和第二车体，第一车体的后端设置有第一车体铰接部后端，第二车体的前端设置有第二车体铰接部和支撑部，转向架总成的中央牵引销上安装有牵引下心盘组件。该结构实现了前后车厢与转向架的固定，但是无法同时实现扭转和偏转解耦。After searching, it was found that CN110182240A discloses a straddle-type monorail vehicle body and bogie connection structure and a straddle-type monorail vehicle, wherein the straddle-type monorail vehicle body and bogie connection structure comprises a first car body, a bogie assembly and a second car body arranged in sequence, the rear end of the first car body is provided with a rear end of a first car body hinge part, the front end of the second car body is provided with a second car body hinge part and a support part, and a traction lower center plate assembly is installed on the central traction pin of the bogie assembly. This structure realizes the fixation of the front and rear carriages and the bogie, but cannot realize torsion and deflection decoupling at the same time.

发明内容Summary of the invention

本专利所要解决的技术问题是：克服上述现有技术的不足，提供一种低地板面跨座式单轨铰接转向架，扭转及偏转解耦，传递牵引力、制动力，缓解及衰减振动冲击。该发明集成简化车辆间结构，减小轴间距离，实现轮仓更小及更靠近贯通道，充分利用车端空间，增大客室内有效利用面积。The technical problem to be solved by this patent is: to overcome the shortcomings of the above-mentioned prior art and provide a low-floor straddle-type monorail articulated bogie, which can decouple torsion and deflection, transmit traction and braking force, and relieve and attenuate vibration impact. The invention integrates and simplifies the structure between vehicles, reduces the distance between axles, realizes a smaller wheelhouse and is closer to the through-passenger channel, fully utilizes the space at the vehicle end, and increases the effective utilization area in the passenger compartment.

本专利解决其技术问题所采用的技术方案是：低地板面跨座式单轨铰接转向架，包括转向架构架，其特征在于：转向架构架构架中央处设置有铰接牵引结构，所述铰接牵引结构包括：弹性支撑于转向架构架的中心牵引座、分别与相邻两车体固定的第一铰接座和第二铰接座，所述第一铰接座下部与中心牵引座连接，所述第一铰接座和第二铰接座通过橡胶关节轴承铰接，所述橡胶关节轴承的中心线沿车辆横向方向设置。The technical solution adopted by this patent to solve its technical problems is: a low-floor straddle-type monorail articulated bogie, including a bogie frame, characterized in that: an articulated traction structure is arranged at the center of the bogie frame, and the articulated traction structure includes: a central traction seat elastically supported on the bogie frame, a first articulated seat and a second articulated seat respectively fixed to two adjacent car bodies, the lower part of the first articulated seat is connected to the central traction seat, the first articulated seat and the second articulated seat are articulated by a rubber joint bearing, and the center line of the rubber joint bearing is arranged along the lateral direction of the vehicle.

本发明所述转向架牵引铰接结构包括第一第二铰接座中心牵引组成，分别与前车厢、后车厢及转向架构架相连。牵引铰接结构可以实现前后车厢间点固定，扭转及偏转解耦，传递牵引力、制动力，缓解及衰减振动冲击。The bogie traction articulated structure of the present invention comprises a first and a second articulated seat center traction component, which are respectively connected to the front car, the rear car and the bogie frame. The traction articulated structure can realize point fixation between the front and rear cars, decouple torsion and deflection, transmit traction force and braking force, and relieve and attenuate vibration impact.

本发明所述转向架为双轴转向架，具有自稳定性，相比跨座式单轴转向架有更好的抗点头性能。采用铰接方式，减少了轨道不平顺对整列车的激励输入，运行稳定性和平移性好。过曲线时铰接式车辆中相邻车辆的相对横向位移较小，车体相对较短，车辆通过曲线性能好。The bogie of the present invention is a double-axle bogie, which has self-stability and better anti-nodding performance than the straddle-type single-axle bogie. The articulation method is adopted to reduce the excitation input of the whole train due to track unevenness, and the running stability and translation performance are good. When passing through a curve, the relative lateral displacement of adjacent vehicles in the articulated vehicle is small, the vehicle body is relatively short, and the vehicle has good performance in passing through curves.
