The braking system is a very critical configuration on the vehicle. To judge the performance of a vehicle, the braking ability is very important. Generally speaking, the common vehicle braking methods are mainly air brakes and oil brakes.

Vehicle shaking is a problem encountered by many drivers, especially when the vehicle is braking, the body will vibrate as soon as the brake is stepped on. Although sometimes it does not affect the vehicle to slow down or stop, it is somewhat worrying. After all, vehicle braking is directly related to driving safety.Under normal circumstances, the shaking of the vehicle when stepping on the brakes is closely related to the braking system and chassis components. Specifically, the reasons can be found from the following aspects.1.

The water spray cooling device is often seen on drum brakes in running mountainous areas. When driving in mountainous areas, there are many ups and downs and sharp turns, especially on long downhill roads. It takes a long time and frequent braking. The brakes are prone to thermal attenuation and lead to brake failure. Therefore, many car owners choose to install water showers to cool down the brakes trailer axle.However, as the temperature continues to drop, many cities in the north have issued bans on the use of showers.

How to cool the trailer's braking system is an old topic. When the trailer is carrying goods, the inertia is large, and a few brakes will appear the brake heat.

The hydraulic retarder, also known as the hydraulic deceleration device, can achieve deceleration braking under non-emergency braking that can be predicted in advance such as long downhill, so as to reduce the use of brakes and avoid problems such as brake failure caused by long-term braking.According to the previous regulation JT/T1178.2 issued by the Ministry of Transportation, from September 1, 2020, newly produced tractors must be equipped with hydraulic retarders or other auxiliary braking devices trailer axle.But in reality, many owners are not willing to install liquid slow, in addition

The full name of ABS is the anti-lock braking system. It is a device that prevents the wheels from locking and keeps the wheels and the road at friction when the vehicle is braking. After installation, it can improve the braking performance of the vehicle and enhance driving safety.

With the continuous development of the domestic transportation industry, the requirements for vehicle production technology are becoming more and more stringent. According to the provisions of GB7258, dangerous goods transport vehicles, three-axis fence trucks, three-axis grid vehicles must be equipped with disc brakes.

Under the implementation of the national standard GB7258, the tractor-trailer is also affected by no small amount, in addition to the truck charges to be charged according to the axle, another important standard is that many trailers factory to standard the axle of the distribution brake and air bag suspension.Most of the trailers we are running on the road now are rigid suspension and drum brakes, if the newly registered trailers are all changed to disc brakes and air bag suspension, the cost of car owners will be much higher.The picture is disc trailer axle and drum trailer axle, the followi

1. Core Principle DifferencesDisc Brake Axle:Uses opposed calipers to clamp the brake disc Open cooling structure Hydraulic/pneumatic piston force transmission Typical response time < 0.3 seconds Drum Brake Axle: Brake shoes expand radially to contact the drum Enclosed design Force transmission via S-cam mechanism Typical response time 0.5–0.8 seconds Technical Note: Disc brakes have 60–80% larger effective cooling area than drum brakes.2.
