As an important forklift component, the steering system is inevitably prone to some malfunctions in daily use. It is undoubtedly troublesome to go to a repair station for maintenance every time a malfunction occurs. Therefore, it is important to pay attention to self maintenance in daily use. Let's take a look at the common fault analysis of forklift parts steering system together:
1、 Forklift steering system composition: The forklift steering system consists of a steering device, a steering axle, etc
2、 Forklift steering device: It consists of a steering wheel, upper shaft assembly, universal joint, lower shaft assembly, bearings, shaft couplings, lower steering pipe, steering gear, priority valve, clamping handle, hydraulic switch, etc. The steering wheel angle can be adjusted forward and backward according to the needs.
3、 Steering axle: Adopting a transverse hydraulic cylinder steering system, steering is easier, more convenient and reliable.
4、 Common troubleshooting methods for steering system:
1. Oil leakage
Inspection: The sealing ring of the steering cylinder is damaged or the pipeline is subsequently damaged. Exclusion: Replacement
Inspection: The sealing ring at the hub bearing or support bearing is damaged. Exclusion: Replace the sealing ring
5. Mismatched steering angle of left and right drive wheels (front wheels)
Check: Controller parameters are incorrect. Exclusion: Adjustment
2. The steering operation is laborious
Inspection: The pressure of the diversion valve is too low. Exclusion: Adjust pressure
Inspection: There is air in the oil circuit. Exclusion: Eliminate air
Inspection: The steering gear fails to reset, the positioning spring is fragmented or lacks elasticity. Exclusion: Replace the spring plate
Inspection: There is too much leakage in the steering cylinder. Exclusion: Check the piston seal
3. Abnormal noise from the steering system
Check: The hydraulic oil level is too low. Exclusion: Add hydraulic oil
Inspection: The steering gear shaft and rack are damaged. Exclusion: Replacement
Inspection: The supporting shaft is damaged. Exclusion: Replacement
Inspection: Insufficient lubrication. Exclusion: Add lubricating grease
Inspection: The suction pipe or oil filter is blocked. Exclusion: Cleaning or replacement
4. The steering wheel cannot be turned:
Inspection: The oil pump is damaged or malfunctioning. Exclusion: Replacement
Inspection: The priority valve is blocked or damaged. Exclusion: Cleaning or replacement
Inspection: Damaged rubber hose or connector or blocked pipeline. Exclusion: replacement or cleaning
