Automobile doors also use hinges, so where is the door hinge? Generally speaking, it is the front tailgate. This position needs frequent maintenance, otherwise it will cause great damage, such as heavy door opening and squeaking with dry friction. Then, in the maintenance of the door hinge, the best answer to the question of what lubricating oil is used for the door hinge is lubricating oil or butter, and the lubrication effect is better. Specifically, about which part of the door hinge is and what kind of lubricating oil is the best for the door hinge, come with me to see the article! 1. Where is the door hinge?

Automobile door hinges are installed in the front tailgate, and the hazards of non-maintenance are as follows:

1, the connection between the door and the car body is actually similar to the connection between the door and the wall at home. There are two kinds of revolving doors and sliding doors. Take the most common revolving door in passenger cars as an example. It is installed on the car body through hinges, and then the action of opening and closing the door is the same as that of opening and closing the door at home.

2. So what comes to mind first when the door is heavy or can't be pulled? If the door at home is difficult to open and close, do you think of hinges first? As we know, the hinge needs grease to lubricate the inside to get a smooth sense of rotation. If the grease is lost, the dry friction of the metal will be very dry.

3. In addition, with the passage of time, after the grease slowly passes inside the hinge, the metal surface loses its protection and is in direct contact with air, and the oxidation rust caused by time accumulation will further deteriorate the smooth texture of the hinge. When this jam reaches a certain level, opening the door will not only be heavy, but also be accompanied by a squeak of dry friction.

2. What lubricating oil is the best for door hinges?

The harm of hinge maintenance has been mentioned above, so what kind of lubricating oil is the best for door hinges during maintenance?

The door hinge is lubricated with lubricating oil or butter, and the lubrication effect is better.

1. Before lubrication, the door hinge needs to be wiped clean, and the most common sewing machine oil needs to be injected and turned. It is necessary to clean the rust and stains inside the door hinge before applying lubricating oil. The lubrication effect is very good, and all abnormal noises will disappear.

2. Vaseline can also be used for lubrication. Vaseline is an excellent lubricant. There are two kinds of vaseline, one is medical vaseline and the other is lubricating vaseline. Medical vaseline is less irritating and is often used for skin repair. Lubricating with vaseline will have a very obvious effect First of all, vaseline is not easy to dust, and its waterproof performance is good, and it can be used for a long time at a time.
