汽车后桥的变形和位移,会破坏总成与总成间的正确连接位置。这会加速轮胎和轮毂轴承的磨损、增加燃油的消耗,严重时还会造成半轴扭断等;也会增加车辆运行驶阻力,引起跑偏和制动甩尾现象,影响操纵稳定性,危及行车安全。然而,在车辆综合性能检测中,对后桥的技术状况的不解体检测,目前尚无专用的检测设备。基于这种情况,我们在充分 Deformation and displacement of the rear axle of the car will destroy the correct connection between the assembly and the assembly. This will accelerate the wear and tear of the tire and hub bearings, increase fuel consumption, severe half-shaft torque can also be caused by broken; will increase the vehicle running resistance, causing deviation and brake tail drift phenomenon, affecting the handling stability, endangering Driving safety. However, in the comprehensive performance test of the vehicle, the technical condition of the rear axle is not disassembled and tested. At present, there is no special testing equipment. Based on this situation, we are full
