Troubleshoot the bus steering wheel

    The dynamic balance of the steering transmission device is destroyed, and excessive wear of the transmission shaft and its spline shaft and spline sleeve makes the steering wheel vibrate violently.
    The steering is heavy and laborious. The rolling bearings and sliding oil bearings of various parts of the steering system are too tightly coordinated, and the bearing clearance is poor. The ball pins of the steering longitudinal rod and transverse rod are adjusted too tight or lack of oil. ; Improper adjustment of the front wheel toe, bending or deformation of the front axle or frame; insufficient tire pressure, especially front wheel tires.
    The steering wheel is difficult to maneuver, causing the vehicle to deviate from the following: the specifications or air pressure of the front wheels on both sides are inconsistent; the caster angle of the kingpin or the camber angle of the wheels on both sides is not equal; The spring rate or spring force of the steel plate is inconsistent; the difference between the left and right wheelbases is too large; the gap between the wheel brakes is too small or the brake drum is out of round, causing the brake on one side to be stuck, causing the brake to stall; uneven loading of the vehicle.
       The reasons for the steering wheel trembling or shimmy are: the cushioning of the tires or the repair of the rim causes the dynamic balance of the front wheel assembly to be damaged; the drive shaft assembly has loose parts, and the dynamic balance of the drive shaft assembly is destroyed; the shock absorber fails; the steel plate The spring steel is inconsistent; the steering parts are worn loose and so on.
