If the LED advertising vehicle is heavy when the steering is performed, the driver needs to take into account the need for maintenance. The steering wheel becomes heavier during steering and the LED advertising vehicle is compared during daily use. A common vehicle malfunctions, but if it is not immediately repaired, it will cause the driver to consume more physical strength, and in the event of an emergency, the steering wheel angle will be too late to adjust the direction, and ultimately will cause intention Unexpected consequences. Therefore, once the LED advertising vehicle driver encounters such a situation, it is necessary to drive the vehicle to a professional repair shop for inspection and maintenance. There are many reasons that can cause the steering wheel to become heavier when it turns. The resistance pump in the LED advertising vehicle's steering assist system is the source of its power. Its main task is to convert the power of the engine. Become hydraulic energy, is used to drive the steering system. If it is damaged or worn out, it will directly cause the hydraulic oil output pressure to be relatively low, and it will not be able to drive the steering wheel very well. Eventually, a heavy steering wheel failure will occur. If there is an internal leakage fault or damage to the steering wheel of the LED advertising vehicle , it will cause the steering wheel to turn heavy. This is because the steering wheel is in the system. The main task is to transfer the energy from the hydraulic oil. The conversion becomes mechanical energy to drive the steering mechanism. If there is an internal leakage, the energy of the hydraulic oil will be lost in vain. The resulting condition is that it will not drive the steering mechanism. Then the more common fault is the situation of hydraulic oil. In the LED advertising vehicle's steering power system, hydraulic oil is only the main medium for power transmission. If the hydraulic oil is missing in the system, it will directly lead to The transmission of power was interrupted, causing heavy steering. The resistance pump itself is also required to be lubricated by hydraulic oil, and if there is a shortage of oil, it may also cause its wear and it will lead to the difficulty of turning the LED advertising vehicle .
