"The paper must come to an end, and I never know how to do it." Really understanding the meaning of this sentence, Zeng Qingxing, the product director of the 5-ton loader drive axle, was really stunned by the reality!
By chance, Zeng Qingxing followed the company service staff to the scene and deeply felt a "disassembly difficulty", and his heart was deeply hurt! The original difficulty of maintenance and disassembly of the integral brake has always been an old problem left over from history, and other loader manufacturers in the industry also have the same problem. But as a product director, Zeng Qingxing has always heard about it, but he didn't take it too seriously. One time when I personally saw and participated in the repair and disassembly of the brakes during an in-depth market research, the entire brake repair took a whole day, which was too long, which really caused considerable maintenance pain for the user. He was determined at the time: this problem must be resolved quickly and thoroughly, saving maintenance time and costs for users, reducing user complaints, and improving the competitiveness and reputation of XCMG products!
After returning from the market, he immediately led the project team members to find a loader for testing, borrowed tools such as wrenches, drilled under the loader, and personally disassembled the drive axle integral brake. The weather is hot and the maintenance space is small. People need to wear a cat on their waists, and they ca n’t use it. They are often repaired at the construction site without proper tools. Each bolt is very laborious. The clothes got wet and dry, but the work progressed slowly.
After a few days of actual disassembly and assembly, he took each step of disassembly and took a photo, and produced the "LW500K / ZL50G loader drive axle overall brake disassembly and assembly instructions" and sent it to the company's service department to guide the market maintenance service work, Try to reduce the user's maintenance trouble as soon as possible.
Then the problem comes again, how can we completely solve this problem? The difficulties of this improvement are mainly concentrated on: first, the overall structure of the machine, the second, the versatility and interchangeability of the spare parts market, and the brake caliper mold. To this end, he made three sets of plans attentively, and repeatedly carried out technical exchanges with supporting manufacturers, constantly improved the plan, and finally changed the integral brake to a split type, and the matter was successfully resolved.
The split calculation of brake braking torque meets the requirements of the whole machine, and the braking effect is better than the integrated brake; the friction material of the friction plate is improved; the brake has good heat dissipation effect; the friction plate is easy to repair and replace. Brake failures have dropped by more than 28%, and there have even been cases where users have specified that they want to purchase drive axles with split brakes.
Comments: Think what the user thinks, urgency the user's urgency, and make it easier for the customer's heart, and worry about the customer's gradual departure. Only by controlling from the source and taking the customer's needs as the starting point of his own work can he keep improving. Xu workers always think so, even more so.
