Front-wheel Apply The Brake Abnormal Knocking Analyssi And Solve Project Of JMC's Commercial Vehicle

Along with our country road's fast development and the automobile speed enhances unceasingly, the safety and the comfort aspect request in high speed travel's automobile are also getting higher and higher. To integrate with the international standards and achieve the first-class in China。All the automotive OEMs enhance the automotive functional performance and increases the engine power, and at the same time set a higher request to its front axle part's performance and the quality. The automobile braking abnormal sound question and the steering wheel vibration questions and so on in running process, has more and more aroused the general customer's attention. This article mainly analyses the cause of the braking abnormal sound of JMC some vehicle type, the technological improvement process, until the braking abnormal sound question has been solved。The paper mainly elaborated the product parameter of the hub with the braking abnormal sound relations, and How does the technological process guarantee the related product parameter process ability. Has determined the type of the braking abnormal sound through the empirical data analysis, and has determined the question base reason through the mechanics aspect analysis, and has determined the technological process ability is insufficient through the data analysis, and has promoted the product process ability through the craft improvement and the correlation data analysis, and finally has confirmed the corrective measure validity through the massive post-sale quality informationThrough this article research, We had determined the braking abnormal sound primary cause of the front wheel of JMC some vehicle type, which provide in the theory and the practice direct instruction on eliminating other type vehicles' similar brake sound phenomenon, and it play the very main role to enhanced vehicles'comfortableness and the safety aspect, and to reduce the vehicular traffic accident aspects and so on。This article play the significant role to promoted the enterprise competitive power, so the achievement of this article research has the significant practical significance and the utility value. Key word:The braking abnormal sound, Process ability, Brake drum...
