involves models: Dongfeng Yueda Kia whole car.
Symptom: Vehicle appear abnormal sound or turn the steering damping force is too large and so on.
Faulty: a steering column assembly of the joint and is not standardized. A steering operation of the vehicle steering wheel by the steering torque transmitted to the steering column and the steering gear assembly joint so as to control the deflection angle of the steering wheel operation of the vehicle is achieved. In dismantling the steering column and universal joints, the problem should be strictly in accordance with the assembly specifications, occur when the assembly includes the following two kinds.
(1) joint locking bolts (upper section or lower section) loose, will produce apparent sound when the movable member is connected Kuang turn the steering wheel, the steering wheel and free travel becomes large, the problem occurs If you do not timely inspection and maintenance, can lead to tooth between abnormal wear transmission components, steering failure problem occurs severe.
(2) too deep yoke assembly, will lead to a universal joint or a steering joint with the bottom of the steering shaft steering interference, abnormal noises will be rotated, and it will exhibit the steering damping is too large.
countermeasures: When handling and steering column universal joint, should pay attention to the following points. The steering shaft and the lock bolt recess of the joint
(1) should be aligned to the steering assembly (FIG), to ensure that the drive member does not interfere with the universal joint between the steering gear.
of the steering shaft locking groove and the joint
(2) the first fastening bolt joint steering shaft when installed, after fastening the steering column universal joint bolt, the bolt tightening torque of 15 ~ 20 N? m.
(3) the occurrence of a vehicle steering column portion and the abnormal noise problem steering large damping force, must first check the mounted state of the joint, poor adjusted as required, the member can not easily replace the normal state.
