Trailer wading these 9 inspection maintenance can not be lazy

Recently, a number of cities across the country appeared heavy rainfall, such extreme weather to run on the freight road owners brought a great test. Although compared with ordinary vehicles, the trailer cab is tall and the chassis is higher, but this does not mean that the vehicle's wading performance is better, so it can still not wade.

But what do car owners do when they have to wade into the water? In fact, there are some tips, today DARO trailer axle to talk with you.

1. Compare the water level depth through the tire before wading.

If the water depth is below the hubcap, and the road is good without potholes, you can rest assured;

If the depth of water above the hubcap, below the tread, it is recommended to change the route, if you must wade, you must ensure that the road has no potholes, careful passage;

If the water depth has not passed the tire surface, decisively stop or replace the route, because the water height has affected the vehicle's fan, radiator operation, secondly, the vehicle battery and chassis are also in the water, at this time if forced to wade, it is likely to cause radiator damage, battery short circuit, vehicle parts into water and other situations, resulting in the vehicle into a flooded car.

Especially when passing through the culvert, pay attention to the fact that many culverts in the country are sunken, and the depth of water in the culvert must be clear, otherwise do not blindly drive into it.

2. Keep low and steady throttle during wading.

After entering the wading section, the speed must be slow and the throttle must be steady. Because the faster the vehicle, the more easily the water will be stirred up, causing the water level to rise, increasing the danger of wading. Second, when the speed slows down, you can better observe the road ahead and get more reaction time. In addition, the vehicle to maintain a continuous and stable power output is not easy to stall.

3, the vehicle stalled in the process of wading.

If the vehicle is stalled in the process of wading, do not worry about a second ignition. Try to get off to see what extent the water level is flooded to the tire, if the water level is below the tire axis, you can start a second time; If you have not passed the tire, do not try to start a fire, immediately disconnect the battery power, contact the insurance company, call for rescue, and retain good wading and risk credentials.

If the vehicle has successfully passed the wading section, the owners should not take it lightly, it is recommended to pull over for the necessary vehicle inspection, mainly to check whether the engine, electrical components are flooded, whether the water prevention device is restored to its original state, whether the radiator is blocked by sand and debris, whether the front and rear axle, transmission shaft, steering device, and whether there are foreign bodies, and step on the brake a few more times. Check whether the braking force is affected to determine whether the wading has an impact on the braking system.

It's just a quick check on the road. If conditions permit, or if the vehicle has been wading for a long time, or has been soaked by rain, it needs more detailed and professional inspection and maintenance. It mainly covers the following five aspects of the three major systems of wheel hub system, brake system and suspension system:

1, wheel hub inspection and maintenance. Long-term rain erosion will lead to the failure of the grease, while the invasion of sediment will cause damage to the bearing, the need to clean up the sediment, water and deteriorated grease in time, and replace the new grease as required.

2, brake inspection and recovery. Above we mentioned that if it is ordinary wading, generally a few brakes can discharge the water in the brake system, but if the vehicle is soaked by rain, it needs further maintenance.

The drum trailer axle needs to clean the remaining sediment inside the brake drum and replace the rusted brake drum or friction sheet; Disc trailer axles require cleaning of brake discs, calipers, or linings. If the water is serious, simple treatment does not work, it needs to be sent to the maintenance point for professional maintenance.

3. Check whether the brake air chamber is flooded. After the water into the brake air chamber, the sand entering with the rain is easy to block the porosity, which needs to be cleaned in time. If the water is serious and there is a phenomenon of holding, it is necessary to replace the parts in time.

4. Check the adjusting arm and camshaft. Long time rain soaking is easy to make the adjusting arm or camshaft return abnormal, not only need to clean up sand, rust, but also clean up the deteriorated grease, re filling.

5. Check the suspension system. If a steel plate suspension is used, it is necessary to clean the plate spring, balance beam, and re-add grease; If it is an air suspension, it is necessary to clean the airbag and shock absorber, and check the height and working position of the airbag when re-inflating, and solve the abnormal situation in time.

Although the trailer wading is a more common phenomenon, but the owners still can not be careless. In addition, try not to park in low-lying areas during the rainy season. Once you find that your vehicle is flooded, report it to the vehicle insurance company in time. If the vehicle is parked at a high place, there is no danger of soaking in water, it should also be checked in time after the rain recedes, and if the vehicle is soaked or the water in the car is serious, you can also report insurance.

From the point of view of wading performance, disc trailer axle is better than drum type.

Because its brake disc is exposed, vertical installation, can not store rain, and with the rotation of the wheel end, the rain on the brake disc will soon be automatically dispersed, does not affect the braking performance, as long as the use of proper, the phenomenon of wading failure basically does not occur on the disc brake trailer axle. If the owner's model is suitable for installation, it is still recommended to use the disc trailer axle. When the owner uses the disc trailer axle with complex driving road conditions, try to use the hydraulic retarders, ABS, EBS, etc.
