1.手动挡车辆行驶过程中车身抖动中国汽车质量网在4月份接连收到关于一汽丰田卡罗拉怠速问题的投诉,具体表现为2挡和3挡2000转左右车身抖动。车辆在特定挡位的特定转速时发生车身抖动,此故障为B5A型变速箱所匹配的4M51-3B437-KD半轴导致。由于任何物体都有其固有频率,当外界震动达到其固有频率时,强迫振动的振幅可能达到非常大的值,这种现象就是共振,车辆都有其共振点,这也是无可厚非的。但专家指出,从车身左右摇摆式抖动状态来看,此故障为任何物体动的振幅振点,这态来看,
1. Manual gear vehicle body shaking in the process of driving China Auto Quality Network in April received a series of complaints about the FAW Toyota Corolla idling, the specific performance of 2 and 3 block 2000 rpm body jitter. Vehicle body jerks occur at a specific speed for a particular gear, which is caused by the 4M51-3B437-KD half-shaft that matches the B5A gearbox. Since any object has its own natural frequency, when the external vibration reaches its natural frequency, the amplitude of the forced vibration may reach a very large value. This phenomenon is the resonance and the vehicle has its resonance point, which is understandable. However, experts point out that from the body swinging jitter state of view, this fault is the vibration of any moving object vibration point, this state of view,
