Problems solved by technology

Since the virtual rail train uses rubber tires instead of the bogies of traditional rail vehicles to run on ordinary roads, the load conditions and operating conditions of the car body bearing structure are obviously different from those of rail vehicle bodies running on rails. There is no mature case of car-like load-carrying structure

Embodiment Construction

[0027] refer to figure 1 , figure 2 , The car body structure of the present invention mainly includes: an underframe 1, a side wall 2, an end wall 3, and a roof 4.

[0028] refer to image 3 and Figure 4 , The underframe 1 of the present invention mainly includes: a first-end underframe 101, a wheel area arch beam 102, a low-floor area skeleton 103, a second-end underframe 104, a hinged support 105, and a suspension interface mounting seat 106. The one-end chassis 101 and the two-position chassis 104 adopt a high-strength truss-type steel skeleton structure, mainly using channel-shaped steel materials and square steel pipes, and lightening holes are set on the beams; the beams are connected by channel-shaped longitudinal beams; the skeleton The upper and lower planes are supported by grooves and square columns; the reasonable arrangement and welding of beams, longitudinal beams, and columns form a truss-type steel skeleton structure arranged in a circle, which realizes a ...

Abstract

The invention provides a car body structure of a virtual rail train, which includes a chassis, a side wall, an end wall, and a roof, and is characterized in that: the chassis also includes a wheel area arch beam, and the wheel area arch beam is arranged Between the frame of the section frame and the bottom frame at the first end and the bottom frame at the second end, the shape is an arch that matches the outer contour of the wheel. The steel frame structure of the side wall is provided with a wheel area diagonal brace on the upper side of the wheel position. Each of the Crossbeams are arranged between the wheel area braces on the upper side of the wheels, the outer trim panels are fixed outside the steel skeleton of the side walls, arched openings are arranged at the wheel positions of the outer trim panels of the side walls, and the end walls include left and right retaining panels. panels, upper beams and wall panels, both sides of the upper beams are fixedly connected to the side walls, the upper side is fixedly connected to the roof aluminum profile, the left and right baffles are fixedly connected to the side walls on both sides, and the wall panels are fixedly connected On the outside of the left and right baffles and the upper beam. Between the suspension and the car body, the force is continuously transmitted to the main structure of the car body through the arch beam and transition beam on the underframe, which improves the force transmission path.

Description

technical field [0001] The invention belongs to the field of non-wheel-rail contact-guided transportation under the operating environment of public right of way, and in particular relates to a car body structure of a virtual rail train. Background technique [0002] At present, urban rail transit mainly includes subway cars, trams, light rail cars, etc. Although each has its own unique advantages, compared with road public transportation, it has large investment, high operating costs, and long construction period. At the same time, the tracks are specific. In order to meet the needs of low cost of route construction, less use of ground resources, low traffic pressure in the city, and environmental protection, a new generation of virtual rail trains has emerged as the times require. The virtual rail train has a low-to-medium capacity system, and has the advantages of both trams and buses. It does not need to lay steel rails and does not damage the road surface. , adopts all-...
