Carefully look at the novice will know the car repair and maintenance knowledge
The ball screw drive is an assembly that converts rotary motion to linear motion (or vice versa). It consists of a ball screw and a ball nut packaged as an assembly with recirculating balls. The interface between the ball screw and the nut is made by balls which roll in matching ball forms. With rolling elements, the ball screw drive has a low friction coefficient (typically up to 98%). The forces transmitted are distributed over a large number of balls, giving a low relative load per ball comparatively.

Car maintenance is a big problem. Many newcomers who have got a driver's license have bought a new car. They are still careful on the road, but they do not know much about car maintenance. The driver's license network specifically introduces the car repair and maintenance knowledge to all novice friends.
1, conventional maintenance do not have to change to 4s shop maintenance and repair money to save a lot of tricks, a maintenance station owners told reporters that conventional maintenance in fact the owner has a place to save money. Normally, when the owner performs routine maintenance, the four filters will be replaced. In fact, in these four filters, except that the oil filter and the oil must be replaced according to the driving mileage, the air filter, the gasoline filter, the air-conditioning filter, etc. may not necessarily be replaced every time. The car owner can replace it once or twice, depending on his driving conditions. Of course, the premise is that the staff in the service station need to check to make sure that the parts are not damaged.
In addition: Although routine maintenance time is based on mileage, it can be extended in some cases. For example, your car is usually driven in good urban conditions. The original 5000 kilometers of maintenance can be extended to 6000 kilometers and then maintained.
2. It is advisable to pay more attention to the replacement of parts. Some repair stations are pursuing profits. They will be advised to replace some unnecessary replacement parts and increase the burden on the owner. In this regard, a repair station master told reporters that some parts can be repaired as far as possible repair, can not be replaced when repaired, such as front and rear bumpers, doors, covers, etc., if the impact of bending is not serious, the repair costs far Far less than the cost of change.
The owners have reported to reporters that there are many replacements for the 4s shop. For this reason, the owner of a service station reluctantly stated that on the one hand it is because the technical level of the car is getting higher and higher, especially the maintenance of electronic components. It is difficult to guarantee the quality of repairs. On the Other hand, currently, manufacturers rarely provide parts and equipment maintenance equipment or technology to service stations. Therefore, many times they can only rely on replacement.
3, the price to shop around in many consumers in the impression of the same brand 4S shop repair stations and special service stations parts prices and working hours should be the same, in fact, not the case. The Dongfeng Peugeot Yuhua Yu Rui store's bow total revealed to reporters, the more commonly used accessories, the more consistent the price of the family store, because the manufacturers of commonly used accessories in the same brand different 4S shop prices are the same, but some "cold" accessories, Because the frequency of replacement is not high, there is still a difference between the price of each shop, sometimes there will be a lot of difference. He explained that the difference in loan time and time between different repair stations is different; it causes the price of cold accessories to be different. Therefore, when replacing, the owner may wish to make several more calls. If he compares them and then replaces them, he will save a lot of money.
4, make full use of free testing services In order to establish their own brand image, to attract more consumers, now the major domestic auto manufacturers annually hold a variety of free testing activities.
In the free testing activities, some maintenance personnel will use the opportunity to induce the owner to carry out some unnecessary maintenance and repair, so as to achieve profitability. However, as long as the owner leaves his mind, for example, to a different service station for consultation, or to find a friend of the line to ask, it will not spend money. However, the reporter believes that during free testing, if the owner can take the time, try to go for a bit, so that the owners more easily understand the vehicle condition, and some hidden dangers in a timely manner.
5, usually driving less bumps for many novices; in addition to normal maintenance, the maintenance costs are big, the reporter learned from a number of brand maintenance stations; owners of the vehicle to come to a considerable part of the vehicle is doing sheet metal and spray paint, only this Expenditures are relatively large, because hundreds of oceans have to be sprayed with paint. The bow of Dongfeng Peugeot Yuhua Hao Rui said that for these owners, the first is to find a good insurance company, to buy a car damage insurance for your own car, to reduce their own losses; In addition, it can only be Be careful when driving yourself to avoid bumping.
6. Don't be too old to enter the pits. “Some car owners cherish the car too much. For example, the maintenance period is 5,000 kilometers; but only if he ran for 3,000 or 4,000 kilometers, he would have to change oil and filter.†Henan Xulong Service Station The owner of the king said that the owner did not have to do so at all. Simply follow the manufacturer's regular maintenance schedule for maintenance. Premature maintenance and replacement are wasted.
There are also some owners are too nervous about the performance of the car, the car has a little problem to quickly go to the repair shop to go, a repair shop master Wu believes that many cars are carrying some problems are normal, it is irrelevant, the owner Being too nervous will allow the car to be repaired and get rid of some problems.
7, do not have to pay close attention to 4S repair station vehicle warranty period, you must do maintenance in the 4s shop, if the warranty period is not in the manufacturer specified location maintenance, once the vehicle has a problem, it is not within the scope of the manufacturer's claim, it may It's a big loss.
The owner of the car, Mr. Sun, told the reporter that after the car had passed the warranty period, he changed to his familiar repair factory to handle some minor problems. Not only was the material cheaper, but the working hours were also cheaper. The same maintenance project saved at least half the cost. In the same way, Mr. Wu, who is more knowledgeable about the car, is also a small problem that saves money. He usually solves his problems by himself, doing maintenance to buy materials in the Auto City, and then looking for a master to do maintenance for the car. However, he will choose to go to a formal repair shop to solve the big fault.
