摘　　要：VOLVO矿用铰接式卡车是一种通用性强的土方运输车辆。由于铰接机械结构,该铰接式卡车在恶劣的气候、地形等复杂情况下具有很高的实用性。前后连接的铰接器是VOLVO铰接式车的关键部件,后车架带有永久润滑滚子轴承的旋转铰链连接。作为车辆关键连杆部件的前车架铰链销孔和销轴比其他机械部件更容易磨损。因此,铰接器机械部件在恶劣的条件下承受沉重的负荷,前车架铰链销孔与销轴的连接部位易受到外力、重心叠加等复合载荷的影响,导致铰链销孔衬板变形、开裂、销轴异常等故障频发,对设备利用率和运行安全造成不利影响[1]。本文将通过分析和处理,提高设备的利用率,解决安全隐患,降低生产成本。The VOLVO articulated truck is a kind of mining-machine as earthwork transport vehicle with strong versatility.This articulated truck’s mechanical structure is practical for dealing with the harsh climates and complex terrain.The knuckle joint is the key part of VOLVO articulated truck connecting the front and the rear parts,and the rear truck frames is connected to the knuckle joint with a permanent lubrication cone roller bearing.On the other hand,as the key link parts of the vehicle,the front frame pinhole and pin shaft would tend to wear out more than other mechanical parts.As a result,these mechanical components work under heavy loads in harsh conditions,so the connection parts of the front frame pinhole and pin shaft are easily affected by the force,the gravity and other composite loads;therefore,the deformation of the pinhole lining plate,cracking and other faults would happen frequently and cause negative influence on equipment utilization rate and safety[1].This article will improve the utilization rate of the equipment,solve the hidden danger of safety,and reduce the cost by analysis and treatment.
