The working principle of the cover strut.
The working principle of the hydraulic press cover support rod mainly relies on hydraulic technology, by adding high-density liquid or gas material in the sealed space, and then pumping out the air inside, adding something like a piston outside, so that the high-density liquid material produces energy in the compression. This design allows the hydraulic rod to provide the required support force when under pressure, and the hydraulic buffer relies on the hydraulic damping to cushion the object acting on it to slow down to a stop, playing a certain protective role.
Unlike hydraulic cover struts, hood ejection systems involve more complex technology, including components such as pedestrian impact sensors, air pressure chambers, engine ejection struts with air pressure pistons, and airbag ECUs. Its working principle is to control whether the engine cover springs up through the pressure change of the air pressure chamber. When the vehicle encounters a pedestrian while traveling, the pedestrian collision sensor located behind the front bar foam of the engine senses the pressure change in the air pressure chamber and sends the relevant signal to the airbag ECU. After receiving the signal, the airbag ECU automatically matches the data originally stored inside it, and according to these data, it can determine whether the signal detonates the engine cover ejection with the pressure piston or determines that the problem is faulty.
Is the cover brace buckle broken
The cover brace buckle is broken under normal circumstances does not affect normal driving, but it needs to be repaired in time to avoid potential safety hazards.
In most cases, the breaking of the fixed clip of the cover stay rod will not directly affect the driving ability of the vehicle, so it can be regarded as not affecting normal driving. However, this does not mean that the problem can be ignored. If the buckle is damaged, you are advised to purchase a new buckle to ensure that the cover can open and close properly.
In a specific environment, such as the cold winter in the north, the cover support rod may fail, then you can use a strong magnet and appropriate glue for temporary fixing. However, this method may not be a long-term solution, so if the problem persists, you should consider replacing it with a new clip or seeking a professional car repair service.
In extreme cases, such as a snap snap that causes the support rod to fall on a critical part of the engine, it can pose a serious safety hazard. Therefore, enough attention should be paid to the small problem of the cover support rod buckle to avoid potential safety risks.
How to install the hood manual support rod
Automotive hydraulic rods are usually used in the trunk or the hood. It is a support device to facilitate the driver to open the hood to check the engine compartment, perform oil checks, antifreeze checks, etc., to prevent the hood from falling down. Similarly, the tailbox hydraulic rod is a device that supports the tailbox to facilitate personnel to place or take out items in the tailbox.
If the hydraulic support rod strength is insufficient, then, it is very inconvenient. Lack of hydraulic rod strength is usually caused by oil leakage. It is mainly caused by the aging of the internal sealing ring, or the rupture of the shell.
What if the hydraulic rod doesn't hold?
First of all, we can not repair the hydraulic rod, either go to the repair shop to replace, or purchase their own online replacement.
It's easy to replace yourself. The hydraulic rod has two forms, one is the latch with the lock form; One is a form of screw locking.
When replacing, if it is a latch type, remove the buckle and take down the old rod, install the new rod, and install the buckle. If it is a screw form, tighten the nut when installing.
Secondly, if you do not want to replace, you can take the following methods to use again.
1. Open the hood or trunk. Keep the pole in the best position. Then grind a groove between the hydraulic rod and the housing with a hand grinding wheel or file, and then tie the groove with a wire. Remove the upper end of the hydraulic lever to lower the hood and trunk.
When the hood or trunk is opened again, install the upper end of the hydraulic rod. So reuse.
2, after opening the hood or tail box, find a hard object (such as steel bar) of the same length as the hydraulic rod, tie the hard object to the support rod, and resist the support rod shell, and then remove the upper end of the support rod to put down the hood or tail box.
When it is necessary to open the hood or trunk again, fix the strut in the original upper position. So reusable.
As a reminder, if you do this, because one end is removed, it may lead to abnormal sound of the vehicle during driving, so it is necessary to fix the hydraulic rod in the position, and prevent the hydraulic rod from interfering with other positions and damaging other components.
In fact, many vehicle hydraulic rods now use air spring struts, which have a much longer service life.
