Assembly. Therefore, it is not necessary to wait for the assembly work in a single production line as before, and it is possible to achieve a time required for greatly shortening the entire assembly work flow. In detail, if the combination of the welded head pipe frame 12 and the integrated casting main car 106854.doc 1291930 frame 14 is taken as an example, the mold of the roughening assembly of Fig. 7 is used, and the locomotive 50 is used. In the production process, for the welded head pipe adjacent frame 12 sent to the production line, the head pipe 123 may be firstly matched with the wheel head 51 having the (four) Μ (four) portion, and the wheel having the brake system 58 and the shock absorber. At this time, the body-cast master: the frame 14' is also sent to another production line: the wheel 54, the power and the shifting mechanism 55, the shock absorber and the receiving box 60, etc. After the assembly of the welded head tube car (4) and the _ master car (4) and other components are completed, the front and rear parts of the locomotive are combined by the joint portion ΐ2ι and the support portion (4) as described above, and then The assembly of the front and rear wiring and the work of covering the vehicle casing, that is, the manufacture of the skating type locomotive 50. Thus, the assembly structure and welding of the integrated prayer main frame 14 by the frame structure of the locomotive of the present invention. The head f frame 12 is separated and at the same time Since the production line is imported, there is no need to wait for the assembly part of the welded head pipe frame I:, and it is possible to simultaneously carry out its own modular assembly because the 1^T is now greatly shortened. The time required for assembling the work flow. The materials used to cast the one-piece cast head pipe frame 11', 12, and the body-cast main frame 14 can use light metals such as Shao, Magnesium, and Qin. Light metal materials are not only light in weight, but also can be used to reduce the weight of locomotives. They are characterized by sleek and easy to sort and recycle, which is in line with the global environmental awareness. Therefore, when the frame is scrapped and recycled, it is more welded than the previous welded steel frame. Easy: Refining and chemical processing 'and easy to sort and recycle' can greatly improve the recycling efficiency... In addition, 'plastic materials can also be used for casting materials, that is, engineering 106854.doc -12-1291930 plastic, which has high strength and impact resistance. Characteristics such as properties, heat resistance, etc. For example, Dragon 4 can also use composite materials with various materials, strength, rigidity, and early knife resistance, such as fiber reinforced plastics, as casting: body casting The f-frames u, 12, and the body-cast main frame μ= According to the above configuration of the present invention, the left front frame, the right front frame, and the 4 cars are cast with light metal, engineering plastic, or composite material or the like. Compared with the previous locomotive frame, the weight of the frame can greatly reduce the weight of the frame and improve the acceleration performance of the locomotive.
