Description

TECHNICAL FIELD

[0001] The present application relates to the field of guide rail type rail transit, in particular, and especially relates to a guide rail type rubber tire system which realizes the self-adaptive extension function of guide wheels and guarantees the form conversion of RRT between elevated bridges and ground pre-buried tracks with height difference. BACKGROUND

[0002] The guide rail type rubber tire intelligent rapid transit system (hereinafter referred to as RRT) is a new type of rail transit proposed in recent years. RRT can be used as one of the solutions for medium and low volume rail transit systems. Compared with the light rail and tram currently running in the city, RRT has the advantages of lower noise level, lower maintenance cost, shorter maintenance cycle, better curve passing performance and better climbing ability.

[0003] When RRT runs on the urban road surface, rubber tires are used as running wheels to provide traction and support for the vehicle. The guide rail and guide device are special components of RRT. A "H" type guide rail is laid on the running surface. The guide device installed on the vehicle includes a guide frame, a guide arm and a guide wheel. The guide wheel is located on both sides of the guide rail and matches it. The vehicle steering is completed by the guide rail guide.

[0004] As a medium and low volume rail transit, RRT has obvious advantages, but also has certain disadvantages. The guide rail cannot cross the existing road, the laid guide rail cannot be integrated into the existing ground transportation system and affects the urban aesthetics. Special operation lines need to be built, and road rights cannot be shared. The application scene of special road right line laying is highly restricted. High viaducts need to be avoided for existing highways. The line reconstruction and land acquisition cost is high, which limits the market prospect of RRT. SUMMARY

[0005] According to the above technical problems, a guide rail type rubber tire system is provided, which realizes the self-adaptive extension of the guide wheel and the natural transition of the height difference track environment.

[0006] The technical means adopted by the present application are as follows:

[0007] A guide rail type rubber tire system, comprising:

[0008] a guide rail and a guide device;

[0009] The guide rail includes a straight guide rail pre-installed on the road surface or the rail bearing table of the elevated bridge and a transition guide rail used for connecting the elevated and ground connection positions with longitudinal height difference;

[0010] The guide rail is a "H" type guide rail;

[0011] The guide device comprises:

[0012] The guide frame, the guide arm, the telescopic rod and the guide wheel;

[0013] The guide frame is provided with a pair of guide arms at the front end and the rear end, each of which is detachably assembled with a telescopic rod below, and the guide wheel is rotatably assembled on the telescopic rod;

[0014] The telescopic rod is a damping telescopic component;

[0015] The guide rail is clamped in the middle of each group of guide wheels of the guide device, and the central vertical rail surface of the guide rail is in sliding fit with the guide wheel;

[0016] The central vertical rail surface of the transition guide rail has a laterally arranged and protruding guide rail, and each guide wheel is provided with a groove capable of allowing the radial embedding of the guide rail, and when the guide wheel runs to the end of the guide rail, the guide rail is embedded into the groove of the guide wheel, and the guide wheel is forced to drive the telescopic rod to stretch up and down under control through the guide curve of the guide rail, thereby completing the natural running transition of the guide wheel in the transition of the guide rail.

[0017] Further,

[0018] The telescopic rod is a hydraulic damper.

[0019] Further,

[0020] The guide frame and the guide arm are hinged through a cylindrical long pin, and a limiting column is used to constrain the rotation freedom of the guide arm.

[0021] Further,

[0022] The guide arm and the telescopic rod are hinged, and the hinge mode adopts a cylindrical rubber joint, and the telescopic rod has rotation rigidity perpendicular to the guide rail surface relative to the guide arm.

[0023] The guide wheel and the guide frame are mechanically decoupled vertically, and the pre-embedded track is used to realize the use scene requirement of the guide rail type rubber wheel system under the mixed right of way, so that the guide rail type rubber wheel vehicle can run on the elevated bridge with special right of way or on the urban road surface without special right of way, and be integrated with the existing ground line, thereby enhancing the flexibility of line laying, reducing the line reconstruction cost, making the guide rail type rubber wheel system more popular, and having a wider market application scene.

[0024] Compared with the prior art, the RRT of the present application is based on the fact that the current line is mostly in the form of an elevated bridge, and laying the line on the road surface will hinder the normal driving of other vehicles, the telescopic rod can be telescoped with the guide rail, the RRT guide wheel can be guided on the rail supporting platform of the elevated bridge, and can also be guided in the pre-embedded track on the urban road surface, so as to realize the integration of the RRT laying line with the existing road surface, otherwise the line reconstruction engineering quantity is large, the urban appearance is affected, the road resource occupation is large, and the advantages of the RRT cannot be fully exerted.

It is to be understood that the drawings are not necessarily to scale as the dimensions of the parts shown are for the purpose of providing an illustration of the application only and can not reflect the actual proportions of the parts. Techniques, methods, and apparatus known to those of ordinary skill in the relevant art can not be discussed in detail but can be assumed known to those of ordinary skill in the art. In the examples shown and discussed herein, any specific values should be interpreted as merely illustrative and not as a limitation on the scope of the example embodiments. Thus, other example embodiments of the example embodiments can have different values. It is to be noted that like numbers and letters refer to like elements throughout the several views of the drawings and, as such, no further discussions on the same are typically provided. It is to be understood that such elements can be named generally rather than be specifically addressed in each figure wherein such elements appear.

[0046] In the description of the present application, it needs to be understood that the orientation words such as "front, back, up, down, left, right", "transverse, vertical, perpendicular, horizontal" and "top, bottom" and the like indicated orientation or position relationship are generally based on the orientation or position relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, without the opposite indication, these orientation words do not indicate and imply that the indicated device or element must have a specific orientation or be constructed and operated in a specific orientation, therefore, it cannot be understood as a limitation on the protection scope of the present application: the orientation words "inner, outer" refer to the inner and outer relative to the contour of each component.

Thus, the exemplary term "above" can encompass both an orientation of above and below. The devices can be oriented in other ways (rotated 90 degrees or at other orientations) and the spatial relationship terms used herein interpreted accordingly.

[0048] In addition, it should be noted that the use of "first", "second", and the like words of distinction do not connote any meaning of importance, but are used solely to distinguish one element from another, and are not to be construed as limiting the scope of the application.
