The reliability of disc brake is different from the low reliability of long time continuous brake of drum axle. The overall structure of the disc brake is simple, the brake friction surface is directly exposed in the air, and the heat dissipation is better, effectively avoiding the phenomenon of heat recession; The brake disc bears pressure stress and has better crack resistance under continuous braking; The disc brake has no friction boosting effect, and the braking force of the left and right wheels is more average; The braking system has fast reaction speed and is more suitable for the EBS/ABS system.
Therefore, the disc brake has more obvious advantages. The disc brake enables the vehicle to have a more reliable braking effect on mountain roads, long downhills and various complex road conditions. What problems should we consider when selecting the axle of heavy truck trailer?
The impact of good axles on driving safety is self-evident. Next, we will analyze several elements for selecting the trailer axle:
Lightening, reducing deadweight and pulling more goods: In this regard, the axle can be lightened through new materials and technologies, and the deadweight can be greatly reduced on the premise that the strength meets the use needs, which also means that the vehicle can load more goods.
Maintenance free to improve operation efficiency: With the increasing annual mileage of vehicles, the annual mileage of 200000 to 300000 km is very common, which also makes the car owners have a stronger demand for maintenance free. Although the maintenance time has little impact on the operation efficiency, it will still involve part of the business energy. Therefore, it is certain that in the current transportation environment, the trailer axle free of maintenance and long maintenance will be more popular.
As an important part of trailer, the quality of axle is directly related to the operation of users.
