Embodiment 1

[0034] Embodiment 1: as Figure 1 to Figure 3 As shown, a low-floor vehicle fixed hinge hinge method, it is first assembled into a whole metal joint bearing 1 in the low-floor vehicle fixed hinge, and then the integrated metal joint bearing and an upper fixed support of a car body 2 is connected by connecting piece 1 3 and the integral metal joint bearing 1 is connected with the lower fixed support 4 of another vehicle body by connecting piece 2 5, thereby connecting two adjacent vehicle bodies. The metal joint bearings in the fixed hinges of existing low-floor vehicles usually have different structures according to different loads and requirements for the radius of the curve. Since they are mainly used in urban transportation, the radius of the curve is required to be as small as possible. At the same time, urban Design according to the size of passenger flow. As the core component of the fixed joint system, it has high requirements in terms of load capacity and motion trans...

Embodiment 2

[0043] Embodiment 2: as Figure 8 As shown, compared with Embodiment 1, the difference is that a wear-resistant bushing 2 16 is also arranged between the inner rolling ball 8 and the outer rolling ball sleeve 7, and the outer rolling ball sleeve 7 and the wear-resistant bushing 2 16 All through spherical contact between and between the inner rolling ball 8 and the wear-resistant bushing two 16. Wear-resistant bushing 2 16 adopts copper-based PTFE inlay, copper-based graphite inlay, engineering plastics or nylon, the selection of the material of wear-resistant bush 2 16 and the material of wear-resistant bush 1 9 described in Example 1 The selection of is the same and will not be repeated here. Through the setting of wear-resistant bushing 1 and wear-resistant bushing 2, the metal joint bearing in this embodiment has excellent anti-friction lubrication and load-carrying capacity, extremely low friction coefficient, good self-lubricating effect and high Excellent bearing capac...

Embodiment 3

[0045] Embodiment 3: as Figure 9 As shown, compared with Example 2, the difference is that by adjusting the thickness of the wear-resistant bushing 2 16, the gap between the inner rolling ball 8 and the outer rolling ball sleeve 7 is changed, thereby changing the performance of the metal joint bearing. The fixed hinge of the entire low-floor vehicle can be adapted to different working conditions and has wider versatility. This is because by adjusting the thickness of the wear-resistant bushing 2, the structural size of the contact surface of the inner rolling ball or the outer rolling ball sleeve can be changed, thereby changing the structural strength of the product, thereby adapting to the load requirements under different working conditions; in addition, by adjusting The thickness of the wear-resistant bushing 2 can also adapt to the friction requirements under different working conditions.

[0046] In this embodiment, a gap adjusting gasket 18 is provided between the inn...

Abstract

The invention discloses an articulation method of a fixed articulation of a low-floor vehicle and an articulation device of the fixed articulation. The articulation method of the fixed articulation of the low-floor vehicle comprises the steps of firstly assembling metal spherical plain bearing in the fixed articulation of the low-floor vehicle into a whole, connecting the integral metal spherical plain bearing with an upper fixed support of a vehicle body through first connecting pieces and connecting the integral metal spherical plain bearing with a lower fixed support of another vehicle body through second connecting pieces so as to connect the adjacent two vehicle bodies. The articulation method of the fixed articulation of the low-floor vehicle and the articulation device of the fixed articulation change a center pin structure connection method in the prior art, and can not only meet the running requirement of the low-floor vehicle, but also allow the articulation device of the whole fixed articulation to be simple and compact in structure, thereby decreasing the demand for installation space, reducing the difficulty of assembly and disassembly of the whole fixed articulation and reducing the difficulty of maintenance.

Description

technical field [0001] The invention relates to a low-floor vehicle body hinge method and a hinge device thereof, in particular to a low-floor vehicle fixed hinge hinge method and a fixed hinge hinge device. Background technique [0002] Low-floor vehicle Light rail vehicle, hereinafter referred to as low-floor vehicle, is a new type of transportation equipment in modern cities. Generally, there are 3, 5, and 7 vehicles in groups, which are connected by hinged system devices. The distance between the vehicle and the track surface is less than 40 cm. The car body hinge device is an important part of the car body connection of urban low-floor vehicles. At present, with the wide application of low-floor vehicles in Europe, it is also being promoted in China, so the market demand for hinge devices is also increasing. [0003] The hinged device of the car body is arranged at the connecting part of the two ends of the car body, and the upper and lower hinges are generally used. It...
