How to safely trailer?

When a vehicle breaks down, a triangle warning sign should be placed at the rear of the vehicle before inspection. If it can't be repaired, it can only be dragged back. It is best to let the after-sales service car of 4S shop or a professional rescue company tow it.

Secondly, it is necessary to refer to the precautions about trailers in the user manual to remind rescuers. The basic principle is that the towed vehicle should lift its "driving wheel" off the ground, such as front wheel drive.

According to the instructions in the user manual, the vehicle should tow two front wheels off the ground, rear-wheel drive should tow two rear wheels off the ground, and four-wheel drive vehicles should tow four wheels or one or two wheels off the ground. Otherwise the transmission will be seriously damaged.

Whether it is manual or automatic, attention should be paid to:

1, put in neutral.

2. Insert the ignition key and turn it to "ACC" to turn off the air conditioner, stereo and other electrical appliances.

3. The parking brake handle must be released.

4. If the vehicle chassis is injured after the collision and can't walk normally, it is recommended to use a flat car for traction, which is the safest way to tow.

How to maintain the driving system?

The drive system is the key facility to realize the load and driving purpose of the automobile. It not only bears the vertical gravity of the load, but also bears the lateral thrust and resistance caused by acceleration or braking.

Therefore, it is the hardest and hardest part of the car body, and of course it is also the most easily worn and injured part.

The maintenance of the drive system should pay attention to the following aspects:

1. Normal loading according to vehicle requirements. Small cars should not be overcrowded, and the trunk should not be loaded with heavy objects for a long time.

2. When running with full load, don't overspeed to reduce the serious damage to the drive system when braking.

3. When passing through natural roads and sandy roads, you should slow down to reduce the up-and-down amplitude and front-rear collision.

4. When riding a stone on the road, you can't be forced. If there are no other roads to choose from, you must pave the road or clean it before you can pass.

How to prevent the shock absorber from failing?

To prevent the shock absorber from failing, what the driver can and should do is to prevent the abnormal wear of the hydraulic oil seal ring of the shock absorber and make the service life of the shock absorber reach the specified service cycle of the vehicle.

In order to prevent the shock absorber from failing, the following aspects should be paid attention to:

1, reduce the amplitude and reduce the number of up-and-down oscillations of the vehicle. This requires drivers to carefully choose routes before going out, choose flat asphalt roads and cement roads as much as possible, and deliberately avoid rugged natural roads, gravel roads and severely damaged grade roads; Then, when traveling, always pay attention to the choice of road surface, choose a relatively flat road surface, and try to avoid rugged roads.

2. Slow down the amplitude. First of all, we should be able to identify and see clearly the big roadblock in front of the road within the safe field of vision, and then quickly implement deceleration measures, so that when the vehicle approaches the obstacle, it can have enough time to make actions such as bypassing, stopping or passing slowly, thus effectively avoiding the vehicle from oscillating greatly and ensuring that the shock absorber will not be damaged artificially.

3. Avoid overloading. Overload load will make the reverse force of the shock absorber reach the limit, which will not only make the shock absorber lose its damping effect, but also make the rubber sealing ring of hydraulic oil deform under the action of hydraulic pressure, thus causing oil to seep out and directly damaging the shock absorber. More importantly, overloaded bearings will also extend the braking distance, which seriously threatens driving safety.

How to understand the advantages and disadvantages of aluminum rims?

The use of aluminum rims for small cars has become a trend from fashion, and car owners must be clear about its advantages and disadvantages when using them, so as to foster strengths and avoid weaknesses.

Advantages of aluminum rim:

1. Compared with the steel ring, it is simple and easy to make, with diverse and beautiful shapes.

2. Because the density of aluminum is only 1/3 of steel, it is lighter, which can reduce the dead weight, fuel consumption, speed up quickly, reduce the spring load of the bearing system, enhance the vibration reduction effect and improve the ride comfort.

3. Aluminum material has good thermal conductivity, and can quickly dissipate the driving heat generated by brakes and axles.

Disadvantages of aluminum rims:

1, due to the weak strength of aluminum, hard objects or cement kerbs that the wheels collide with the road surface are easy to deform, and cracks will occur when the wear is heavy.

2. Due to the low density of aluminum, there may be "sand holes" lurking in the production process. Once the "sand holes" are connected, the tire will leak.

3. If the alkali resistance of aluminum is poor, it is easy to corrode the surface of aluminum parts when driving on the salted road or washing with cleaning agent.
