Do these vehicle checks before you go out in the summer
Summer is a "tough" season for trailers. Therefore, it is particularly important for the driver to do a good job of inspection and maintenance of the vehicle before going out. If it is not paid attention to, it is easy to lead to a variety of problems in the trailer on the way, resulting in the vehicle "lying down", once the problem appears in the process of high-speed vehicle driving, the consequences will be unimaginable.
Therefore, before the trailer is out of the car, the necessary inspection can not be less, and the so-called "sharpening the knife does not miss the wood worker" is this truth. DARO trailer axle summarizes the trailer detailed out of the check list, owners can follow this check. If there are any omissions, you are welcome to add.
1. Check the trailer tires.
The temperature of the road in summer is relatively high, and the requirements for car tires are more stringent. Check and maintain the tires before going out, and try to ensure that the pressure of each tire is consistent or close to reduce unnecessary wear. For the small stones included in the tire pattern, it is necessary to clean up in time, and check whether there is a crack or air leakage phenomenon to prevent a tire burst.
2. Check the brake system.
Braking is the top priority of driving safety, and it is also a maintenance that must be done before going out. Especially in the rainy season, the road is easy to become slippery, and the coefficient of friction between the tire and the road is reduced, especially when there is water in the tire pattern, the coefficient of friction will be smaller. Therefore, before leaving the car, the vehicle equipped with an automatic adjusting arm needs to check whether the lubrication degree of the adjusting arm is up to standard, and whether there are problems with the air chamber return spring and brake pad tension spring; The non-automatic adjusting arm requires manual adjustment of the brake. At the same time, pay attention to check the degree of wear of key parts such as brake pads, and replace them in time for serious losses.
3, check the oil power line.
Summer is the high incidence of spontaneous combustion of trailers. The main focus of the car is to check the oil and electric lines on the trailer to see if there is aging or need to be repaired and replaced, and to observe whether the jack is loose, so as to prevent problems before they happen. Check whether the drying tank is normal, and clean up water, oil and other impurities in the air storage tank in time; Clean the coarse filter cup to avoid the deposition of water impurities.
4. Check the wheel end system.
Check the wheel hub, bearing, steering knuckle cancellation, camshaft clearance, etc., to see if there is loosening, lubrication is up to standard, if there is lubricating oil deterioration or other substandard situations to be dealt with in time. In addition, the nuts of the leaf spring and other places should also be regularly checked for tightening.
By the way, the fire of the hanging axle head is also one of the reasons for the spontaneous combustion of the trailer, and the abnormal phenomenon such as lubrication or loosening of the wheel end system is one of the reasons for the fire of the axle head. In addition, the owner of the driving process should not step on the brake for a long time, because the friction between the friction plate and the brake drum will generate heat, and if the cooling program is not given in time for a long time, it is easy to lead to the shaft head fire.
5. Check various oils.
Summer vehicles all kinds of oil evaporation speed becomes faster, to often check the liquid level, such as coolant, oil, brake fluid, urea liquid, fuel, glass water, battery electrolyte, etc., to keep the liquid level between the upper and lower limits, insufficient time to add, while covering the outer cover. In addition, pay attention to check whether there are leaks and other problems, and contact the maintenance station in time.
Here also say a word, some owners like to use tap water instead of antifreeze in the summer, which is absolutely undesirable. Professional configuration of antifreeze can not only anti-freeze, high temperature resistance performance is also very good, high-quality antifreeze generally to about 200 ° C may appear "boiling" phenomenon. The use of antifreeze in summer, the water tank is not easy to "open the pot", in addition, it can also prevent rust, descaling, and play the role of vehicle heat prevention and cooling.
6, check the battery power.
If the owner does not often sports cars, do not start for a long time, the vehicle battery will lose power, and it needs to be charged in time to start.
7. Check the "three major parts" of the vehicle.
The "big three" refers to the engine, gearbox and chassis. The "three big pieces" generally do not have problems, but once they appear, they will seriously affect the use of vehicles. Therefore, the "three big pieces" should also be regularly maintained and repaired.
8. Check whether the semi-trailer is firm.
Check whether the railings of the carriage and the rear door are firm and reliable; The cargo must be packed securely; Check whether the main connecting device is cracked, loose, deformed and other phenomena, and whether various auxiliary facilities meet the regulations to ensure the safety and reliability of the traction device.
9. The steering system also needs to be checked.
It is mainly to see the lubrication of the mechanical connection of the steering system, whether the steering oil and filter element are sufficiently clean, whether the steering rod and pressure bearing are normal, and whether there is a gap by shaking the steering wheel up and down.
Some owners may say: I go out early and come back late, which can have time to do such a detailed overhaul? In fact, many of the items on the above list can be serviced on a regular basis. There are also some projects, such as the wheel end system, if you choose a more reliable performance product at the beginning, you can greatly reduce the subsequent maintenance costs, such as DARO maintenance-free trailer axle, the use of domestic advanced "one-piece" heat treatment process, with high rigid bearings, low pressure casting wheels, high heat capacity brake drums and other accessories, while adding the shaft head intermediate frequency strengthening treatment. Ensure stable performance at the same time, effectively extend the maintenance cycle, to help owners improve operational efficiency.
Again, the inspection of the vehicle is only one aspect, and the relevant traffic documents must also be brought. Such as ID card, driving license, employment qualification certificate, driving license, operating license, traffic insurance signs, etc.; Large transport also carry large transport permit; The transportation of dangerous chemicals should carry the escort license, fire extinguisher, anti-static drag strip, etc.
