The domestic hubs are mostly maintenance intervals of 20,000 to 10,000 kilometers. For long-distance logistics tractors, it means frequent dismantling of the wheels. In the process of dismantling, maintenance personnel generally use hammers and other tools to beat and forcibly disassemble, resulting in high failure rate of bearings and oil seals, and early damage of the hub. At the same time, smearing grease also virtually increases the time cost of maintenance. Recently, the Chinese truck network Xiaobian met an old driver in the truck industry. He did not have the above confusion. He used the Konmai hub, which changed the above phenomenon. He said that the maintenance-free technology and visualization of the hub end cap (hereinafter referred to as the visualization module) of the Conley's hub solved the safety concerns and inefficiency of his hub maintenance. What is the advantage of a visualization module? What is a visualization module? The old driver answered the questions for Xiaobian. The old driver told Xiaobian that the visualization module refers to the transparent design of the nylon cover of Conmax's hub cap. As shown in the above picture, he can directly observe the changes of the lubricating oil through the transparent window, including the state of the oil and the amount of oil. He also told Xiao Bian that before the major failure of the wheel, the lubricant in the visual module will be exposed in advance signs, such as: Lubricant discoloration, oil level is lower than the minimum oil level. The old driver told Xiao Bian that he will use one minute to complete the visual inspection before he gets on the train. He can be assured that he can operate safely and improve his safety. Kangmai's technical engineer told the China Truck Network reporter: "In some bearing manufacturers' statistics, nearly 36% of bearing failures are caused by improper bearing lubricating oil filling and deterioration of lubricating oil or grease. The visualization module allows drivers to quickly inspect oil and detect potential safety hazards in time, which is also an advantage of oil lubrication." Conley wheels are also superior to conventional wheels in terms of maintenance. The old driver told Xiao Bian that the Konmai wheels were designed with long maintenance cycles and maintenance operations were very simple. Unlike grease lubrication, maintenance requires “forced†disassembly of the hub to apply grease. Conmme oil lubrication hubs can be used to drain the old oil directly through the oil drain, and then add new oil through the oil filling port, which is similar to the change of oil. Through the visualization module of the hub, the maintenance personnel can easily check the lubricating oil without dismantling the entire wheel end, and the lubrication amount of the lubricating oil is also more easily controlled, and the lubricating oil amount of the hub can be maintained in an optimal state. Cost and Design Restrict Development of Domestic Visualization Modules Since the advantage of the visualization module is so obvious, why does the domestic hub product not use this function? The technical engineer of Combi introduced that because the cost of the front axle is relatively low, 80% or more of the front axle is still in the Chinese truck industry. Using grease lubrication technology. For grease lubrication, it does not make much sense to visualize because the user does not see the real-time status of the grease. The realization of wheel visualization is also related to the product assembly design. At this stage, the domestic conventional hub design is still to install the brake drum inside the hub, so it is necessary to disassemble the hub when replacing the brake drum or brake pad. In contrast, the Conmax hub is to replace the brake drum with an external one. It is not necessary to disassemble the wheel hub when disassembling the brake drum. This is also a necessary condition for realizing the long-life maintenance cycle and visualization module of the hub. Seeing security is what the user needs Currently, the assembly speed of the Conmme hubs in the domestic passenger car market is very high. In the truck sector, the absolute assembly volume of the FAW Jiefang is the largest. In addition, Dongfeng Commercial Vehicles, Auman GTL and EST, and Liuzhou Automobile have also assembled ConMair products. Kangmai's technical engineer predicts: "In the next few years, the visualization of Qianqiao will be the development trend of the domestic truck market." Throughout the course of the answer, the old driver has been saying that the visual module makes security more intuitive and visible security, and he uses it more securely. The safety of a typical conventional hub is not visible to the driver from the outside as “eyes are blackenedâ€, and the visualization module of the Conrad hub turns internal security into visible. From his words, Xiao Bian can feel that for safety, even the old driver with rich driving experience can not be taken lightly and must be seen. And such a product that can be seen as “safe†can be welcomed by drivers. Force Control System at present, there are several models, suitable for different grinding, polishing work. Force control system of flexible control grinding process, according to the position offset of tolerance of workpiece and subtle moment adjustment, the size of the retention in the set range, to ensure the consistency of surface effect. A perfect fusion of robot and can significantly lower the difficulty of debugging, robot control grinding path, force control system to control the grinding force, grinding force can be quantified, the part tolerance or large deformation of sheet metal, stamping, plastic, etc., still can ensure consistent effect, high production realizability.Flexible grinding system is suitable for the grinding and polishing different work scenarios, apply to the 3 c, auto parts, household sanitary products industry, such as automatic polishing, grinding, especially suitable for curved surface, plane and other equipment arc Angle, body can't implementation artifacts environment. 3C Electronics DFC system, Auto Parts DFC system,Household Sanitary Ware DFC systeme, Traffic And Transportation DFC system DARU Technology (Suzhou) Co., Ltd. , https://www.yiwufizz.com

The hub is a very important part for the truck because it is about the driver’s life. The existing domestic hub product maintenance cycle is very short, and there are "violent" operations in the maintenance process, and parts are easily left behind due to process problems.
