The "1m road milling machine for traveling gearbox and working gearbox" developed by Xi'an Heavy Machinery Research Institute has recently passed the technical achievement appraisal organized by the Shaanxi Provincial Department of Science and Technology. The appraisal committee unanimously believes that 1m road milling The machine travel gearbox and work box are advanced in design, excellent in performance, reliable in operation and cost-effective, and have reached the advanced level of international similar products.

The road milling machine is a special equipment used for road maintenance and has developed rapidly in China in recent years. In particular, the small-scale road milling equipment has a wider service surface and market prospects because it can serve various widths of road maintenance. However, in the process of developing milling machines, domestic related manufacturers have encountered a series of problems such as severe heat generation, large noise, constant shifting and short service life of the existing transmission accessory products, which seriously affected the promotion of the host products. In response to this situation, the experts of Xizhong Group have made a new solution based on the full communication with the users and on the comprehensive system analysis and analysis of the application and load status of the milling machine. In the development of new products, through the use of parallel axis return drive structure, the unique technology of grindable interference connection double gear and hydraulic shifting, effectively solve a series of problems, making the newly developed products more reliable, Practical and simple, it solves the problem that the milling machine transmission parts are difficult to support. Up to now, the product has been produced and put into use in nearly 200 sets. After more than three years of use, it shows that the situation is good and has been fully affirmed and recognized by users. This special product also obtained utility model patents and became a product with independent intellectual property rights.

At present, Xizhong is actively accelerating the development of the series of products, and constantly improving and improving in the application, and strive to meet the needs of the market with high-quality products.
