The subway train brake system, commonly known as the “brake” system, is referred to as the “safe wing” of the subway train, which consists of a combination of highly complex, sophisticated and powerful subsystems. In recent days, three orbital traffic brakes are being built faster in high-tech industrial parks in the buffalo area, and in the future professional, efficient “whole-body check-ups” and repairs are being made to the brake system of either the ordinary line train of the chengdu subway or the municipal (suburban) railway train at the “door to the home”。
“it is as if our cars had to be maintained for a certain number of kilometres or for a certain amount of time, that the deep overhaul of the train brake system (e. G. Repair, overhaul) has clear industry standards, usually not exceeding 6 years or 800,000 kilometres and not exceeding 12 years or 1. 6 million kilometres for major repairs.” general manager wang peng fei, orbital equipment development co. Ltd. (hereinafter referred to as “sungdu equipment”) described the fact that, in the past, these “large maintenance”s were typically torn down critical vehicle systems and returned to the original manufacturer or to the vehicle mainframe manufacturing plant, with over 80 types of system parts to be removed for transport in a single column of six sections, and the whole overhaul was time-consuming and costly. Now, locally built overhaul lines can significantly compress the cycle of overhaul, significantly reduce transportation costs and significantly increase the level of autonomous control over operational safety。
According to the information received, in october 2024, the chengdu orbit group introduced the china institute of railroad science and technology as the national flagship for the scientific innovation of orbital traffic. It co-organized the establishment of the company chengdu equipment for iron, which jointly promoted the construction of an equipment manufacturing platform for the south-west region of the orbit traffic brake system to fill the gap in the capacity to repair critical equipment for local orbital traffic。
At present, the company has completed the construction of urban track brake auxiliary control product overhauls, and two production lines for the urban track brake unit, with the capability to perform in-depth inspections of the “tread brake” approach used by mainstream subway vehicles. All efforts are being made to boost the capacity of the city's rail brake-clip unit for the construction of the production line, which is suitable for the “clip-clip” approach of the higher speed (120 km/h). With the construction of the production line, the annual overhaul capacity reached 4,800 units, fully meeting the development needs of the multi-routine, multi-speed orbital network。
This time, the construction of a platform for the orbital traffic bracing system by chengdu township company, is another important initiative of the chengdu orbital group to support the construction of strategic and emerging industrial clusters at the national level of urban orbital transport equipment, which effectively fills gaps in the in-depth overhaul and manufacturing of the local vehicle core subsystem (branching system) and creates synergies with the already existing vehicle towing system overhauls, and the shift to overhauling lines。
“this means that the core overhaul capacity of vehicles, including towing, brakes, has been largely covered, and `the whole car + shift frame + large parts `the core layout of the industry is basically shaped.” according to the head of the chengdu orbiting group, “this is a link to the entire vehicle, which provides a downlink for operational maintenance and a powerful boost to the continuity and upgrading of the `sungdu-sungdu-sungdu-sungdu-sungdu-sungdu-sungdu-sungdu-sungdu-sung-sung-sung-sung-sung-sung-sung-sung-sung-sung-sung-sung-sing”
In recent years, the chengdu orbital group has accelerated the development of new qualitative productivity and the development of a strong orbital transport vehicle core capacity with new “digitalization” technologies. The operation, entitled “standing the park full”, called for the establishment of home-based production lines for key core companies in the orbital traffic maintenance chain and for the construction of a cooperation pole for the intellectual overhaul of domestic urban vehicles. To date, 11 specialized overhaul lines have been completed, including a whole vehicle, rotor frames, gearboxes, air conditioning, etc., and the total vehicle overhaul capacity has been increased to 625 per year。
