Reduce the number of preparatory components required, weld 106853.doc 1291928 processing costs and man-hours, and avoid problems such as lower strength of previous welds. And the 'head tube 11, the left front frame 12, and the right front frame 13 can be separated from the rear frame 15 and sent to the respective production lines at the same time to perform a series of assembly operations, that is, each can be separately Modular assembly. Therefore, it is not necessary to sequentially wait for each assembly work on one production line as in the prior art, and it is possible to achieve a time required to drastically shorten the entire assembly work flow. In detail, as shown in the modular assembly diagram of FIG. 4, in the production process of the locomotive 5, for the head pipe n, the left front frame 12, and the right frame 13 sent to a production line, The head pipe u can be assembled in advance with the front end 51 having the operation portion such as the grip 57, and the wheel 54 including the brake system and the shock absorber π. Thereafter, the semi-circular portion 121 of the left front frame 12 that is sent to the same production line is fitted with the semi-circular tube portion 131 of the right front frame 13 to clamp the head tube U that has been assembled with some other components from both sides, and is bolted or The head tube 11 is fixed by the snap fit. Next, the portions of the left front frame 12 and the pillar portions 122, 132 of the right front frame 13 are bolted or snap-fitted. In this way, the head officer 11, the left front frame 12 and the right front frame 13 can be composed as shown in FIG. 3 (the front frame assembly 14 is shown in the hook, but the front end of the front frame assembly 14 has been assembled. At the same time, the frame 15 is sequentially assembled with the wheel 54, the power and shifting mechanism 55, the shock absorber 59, the storage box, and the like. The assembly of the current frame assembly 14 and the rear frame 15 with other components is completed 106853.doc 1291928 and then 'the rear part of the locomotive is combined by the joints 125, ι35, i5l, 152 as described above'. The wiring assembly guide and the cover of the car, etc., complete the manufacture of the Scooter locomotive 5G. Thus, the frame of the locomotive 1' of the locomotive is due to the assembly of the rear frame 15 and the front frame assembly. 14 cutters are opened on the respective production lines at the same time, so there is no need to wait for the assembly time of the front frame assembly 14, and it is possible to carry out its own modular assembly at the same time. Shorten the time required for the entire assembly process. The materials used for casting the left front frame 12, the right front frame 13, and the rear frame ^ 5 can use light metals such as Ming, Zhen, Qin, etc., and such light metal materials can not only reduce the weight of the locomotive, but also It has the characteristics of fusible and easy to sort and recycle' in line with the increasing global environmental awareness. Therefore, when the frame is scrapped and recycled, the welded steel pipe frame is easier to melt and 'easy to sort and recycle' can greatly improve the recycling efficiency. In addition, cast materials can also use plastic polymers, that is, engineering plastics, which have high strength, impact resistance, and fuel economy. For example, nylon, etc. can also have the advantages of various materials, strength and stiffness. A composite material having a higher edge, such as a fiber reinforced plastic, is used as a material for casting the left front vehicle = two, the right front frame 13, and the rear frame 15. According to the above composition of the present invention, light metal, engineering plastic , or composite material casting the material of the left front frame, the right front frame, and the rear frame, which can greatly reduce the year of the car compared to the previous locomotive frame. Acceleration performance of the locomotive. 里里,叉升 The technical content and technical features of the present invention 巳 disclose "as above" but familiar with this item 106853.doc -13-1291928, the person skilled in the art can still make various kinds based on the teachings and disclosures of the present invention described above.
