A tailgate hinge is a device that allows the door to rotate naturally and smoothly for opening and closing. The tailgate hinge consists of a hinge base and a hinge body. One end of the hinge body is connected to the door frame via a spindle, while the other end is connected to the door leaf. The hinge body is divided into two segments: one segment is connected to the spindle, and the other is connected to the door leaf. These two segments are joined into a single unit via a connecting plate, which features adjustment holes for door gap clearance. Since the hinge body is divided into two segments and connected by a plate, removing the connecting plate allows the door leaf to be detached for repairs. The door gap adjustment holes on the connecting plate include elongated holes for adjusting vertical gaps and elongated holes for adjusting horizontal gaps. This design enables adjustments in both vertical and horizontal directions. Methods for Adjusting Car Door Hinges: Due to design and manufacturing issues, the hinge axis and the stopper rotation axis may become severely misaligned. It is recommended that the angle between the hinge axis and the stopper rotation axis be controlled to ≤3°, and the door hinges should be monitored. If wear or door sagging occurs due to improper assembly during use, loosen all the stopper mounting screws, open and close the door repeatedly more than five times, and then tighten the screws. Ensure the friction surfaces of the stopper are lubricated. Misalignment between the hinge axis and the stopper rotation axis can also be resolved through adjustment. Issues such as rusted or unlubricated door hinges, lack of lubrication in the stopper, worn lock blocks, or improper handle travel can all cause tight door operation. Hinges, also known as butt hinges, are mechanical devices used to connect two solids and allow relative rotation between them. Hinges can consist of movable components or foldable materials. Butt hinges are mainly installed on doors and windows, while hinges are more commonly used in cabinets. They are categorized by material into stainless steel hinges and iron hinges. For enhanced user experience, hydraulic hinges (also known as damping hinges) have been developed, which feature a buffering function when closing cabinet doors, significantly reducing noise from collisions between the door and the cabinet.

How to Properly Identify an Accident Vehicle?

Check if the body paint color is consistent, whether the surface curvature on both sides is smooth, and observe if the paint reflection is reasonable. If there are discrepancies, the vehicle has definitely been repaired, and the repair quality is poor. Place the vehicle on level ground, stand 3 to 5 meters directly in front of it, and observe if the shoulders of the car are at the same height. If they differ, it indicates that the body frame has been repaired or the suspension and shock absorbers were not properly fixed. Observe if the gaps between the engine hood and the fenders on both sides are even; check if the gaps along the door edges are consistent; inspect if the gaps between the headlights, rear combination lights, and the metal body are uniform, and whether their condition appears similar. Also, check if all glass panels bear the same brand logo. Operate all doors by opening them to an angle of 45° to 60° and closing them with normal force. Observe if the doors close tightly, if the sound and force required are consistent. The left and right sides of the vehicle are symmetrical, including original weld points, fixed screws, and their positions. Therefore, comparing both sides for consistency can help identify any signs of repair.

How many points will be deducted for occupying the overtaking lane for a long time?

Occupying the overtaking lane for a long time is considered as driving not in accordance with the prescribed lane, and the penalty is a deduction of 3 points and a fine. On highways, occupying the overtaking lane for a long time and not allowing vehicles behind to overtake is an uncivilized and unethical behavior, and traffic police will impose penalties according to the law. The overtaking lane is located on the leftmost lane of the highway. It is only set up when the road meets the standards of a six-lane highway in both directions. The overtaking lane is provided for vehicles that need to overtake or meet the speed requirements. However, some drivers occupy the overtaking lane for a long time, forcing other vehicles to overtake from the slower lanes. Highways should clearly mark the speed limits for each lane. The maximum speed should not exceed 120 kilometers per hour, and the minimum speed should not be lower than 60 kilometers per hour. On highways, the maximum speed for small passenger cars should not exceed 120 kilometers per hour, while other motor vehicles should not exceed 100 kilometers per hour, and motorcycles should not exceed 80 kilometers per hour.

Is Wheel Balancing Necessary When Replacing Four New Tires?

Wheel balancing is necessary when replacing four new tires. Below is a partial introduction about tire replacement: 1. Four-Wheel Alignment: Four-wheel alignment is based on the four-wheel parameters of the vehicle, adjusted to ensure good driving performance and certain reliability. It is required after replacing or adjusting the suspension system, replacing steering system components, or after repairing accident-damaged vehicles. Minor scrapes that do not affect the chassis or suspension do not require alignment. 2. Front Wheel Alignment: The installation of the vehicle's steering wheels, steering knuckles, and front axle has a certain relative position. This installation with a specific relative position is called steering wheel alignment, also known as front wheel alignment.
