Fault diagnosis of high-speed swing head in mechanical steering system
1) Fault phenomenon: The steering wheel shakes while the car is driving, thefront of the car swings left and right in the transverse plane, and the drivingis unstable. There are two situations: occurring at a certain speed within thehigh-speed range; The higher the speed, the more severe the above phenomeno 2) Reason for malfunctilon () Tho steanng whasd is urb 2 The front wtieel alignrneant is inccred 5 Front axle (full axle type) bendin!ation oreform ( The wnoel dofiection is large. dacanamnt hterference of stearng tr 5) The frame and acle are dofarmed ⑥ The suspension system has malfunctioned. Unequal stiffness of left and rightsuspensions, spring breakage, failure of shock absorbers, failure of guiding devicesetc. 3)Fault diagnosl ① Appearance inspection. Check if the shock absorber has failed. lf there is oilleakage or failure, it should be replaced, Check if the left and right suspensionsprings are broken and if their stiffness is consistent. lf they are broken or haveweakened elasticity, they should be replaced, Check if the suspension spring issecurely fixed and if there is any movement interference in the steering transmissic n mechanism. lf there is, it should be ruled out.(2 Support the drive axle, plug the non drive wheels with a tripod, start the angine and gradually releas 紧度 Post time: 08-09-2025
