What is a Tractor Truck?

Tractor trucks generally refer to large trucks or semi-trailers where the cab and trailer are connected by a towing mechanism. This means the cab can detach from its original trailer to tow other trailers, and the trailer can also detach from its original cab to be towed by other cabs. Introduction to Tractor Trucks: Tractor trucks generally refer to large trucks or semi-trailers where the cab and trailer are connected by a towing mechanism. This means the cab can detach from its original trailer to tow other trailers, and the trailer can also detach from its original cab to be towed by other cabs. The front part with driving capability is called the tractor, while the rear part without driving capability is called the trailer, which is pulled by the tractor. Connection Methods Between Tractor and Trailer: There are two types: The first is where the front half of the trailer rests on the fifth wheel coupling at the rear of the tractor, with the rear axle of the tractor bearing part of the trailer's weight. This is known as a semi-trailer. The second type is where the front end of the trailer is connected to the rear end of the tractor, with the tractor only providing forward pulling force to tow the trailer without bearing its downward weight. This is known as a full trailer.

What are the consequences of not scrapping a motor vehicle for the owner?

If a motor vehicle is not scrapped and is registered under one's own name, it will affect the renewal or annual inspection of one's driver's license. Driving a scrapped vehicle and getting into an accident: If an accident occurs while driving a scrapped vehicle, even if the other party is largely at fault, in cases involving personal injury or death, the owner will still be required to bear the compensation limit of the compulsory traffic insurance. More seriously, if the accident results in serious injury to one person, the owner will be held primarily responsible and may face criminal charges. Driving a scrapped vehicle is an aggravating circumstance, and normally, probation will not be granted. Consequences of selling the vehicle as scrap: If the owner sells the vehicle as scrap, identifiers such as the engine number and chassis number may be retained by some criminals and installed on other vehicles. If such a modified vehicle is involved in an accident, authorities can trace these identifiers back to the original owner, who will undoubtedly face some trouble and unnecessary losses.

Can a car key that cannot be pulled out be duplicated?

Can a car key that cannot be pulled out be duplicated? It can be duplicated at a 4S store or a brand repair shop. Introduction to car keys: A tool for switching cars. Nowadays, car keys all use chips, which are part of a magnetic chip system. The reading coil of the car ignition lock cylinder will read the chip in the key; each chip has fixed digital information. Advantages of car remote keys: A remote key refers to a key that can open and lock doors from a distance without inserting the key into the lock hole. The biggest advantage is: regardless of day or night, there is no need to locate the lock hole, and unlocking and locking can be done remotely and conveniently.

What Causes the Abnormal Noise When Turning in Four-Wheel Drive?

Abnormal noise during turning can be caused by the following reasons: Lack of oil in the shock absorber's plane bearing: Open the hood and listen to see if the sound is coming from the top of the shock absorber. If the noise is from the plane bearing of the shock absorber, you can apply some grease to the plane bearing. If the noise persists after greasing, replacement is the only option. Loose or damaged stabilizer bar bushings: Check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings can cause noise not only when turning the steering wheel but also when driving on uneven roads. Loose bushings can be fixed by adding shims, but damaged ones must be replaced. Turn signal return clip: If the noise occurs only when turning the steering wheel after activating the turn signal, it is likely coming from the return clip of the turn signal auto-return mechanism. The noise will click once when turning the steering wheel and three times per full rotation because there are three auto-return positions on the steering column. This noise will disappear once the turn signal is turned off. Steering column dust cover: If you hear noise coming from below the steering wheel whenever you turn it, whether stationary or moving, check the steering column dust cover. A lack of lubrication in the dust cover can cause dry friction noise. Applying grease inside the dust cover will eliminate the noise.

Is a cold tire pressure of 2.5 and running pressure of 2.7 considered high?

A cold tire pressure of 2.5 and running pressure of 2.7 is considered high. The recommended tire pressure is between 2.2 and 2.5 bar. If the tire pressure is too high, it will reduce the contact area between the tire and the ground and accelerate the wear of the central tread pattern. If the tire pressure is too low, it will increase the friction coefficient of the road surface and worsen the vehicle's handling. Recommended cold tire pressure for 1.6L displacement: The recommended cold tire pressure for a 1.6L displacement is 2.3, while the recommended cold tire pressure for 1.2T and 1.8L displacements is 2.4. The cold tire pressure applies to both summer and winter tires. It is normal for the tire pressure to increase after driving due to heat generation. Do not reduce the tire pressure after driving. Check cold tire pressure regularly: Check the cold tire pressure at least once a month and before any long-distance trips. Do not forget the spare tire, and ensure it is inflated to the full-load specified pressure. Incorrect tire pressure will compromise safety, vehicle handling, comfort, and fuel economy, and will accelerate tire wear. If the tire pressure is too low, it may cause significant tire temperature rise and internal damage, leading to tread separation and even tire blowouts at high speeds.

How Many Grades Are There for Motorcycle Engine Oil?

Motorcycle engine oil quality grades are determined by the API standard (i.e., the "American Petroleum Institute" standard). This is a comprehensive measure of the quality of engine oil, with grades ranging from low to high as follows: SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN. Identifying Motorcycle Engine Oil Grades: Motorcycle engine oil grades can be identified by the markings on the packaging. From "SA" to "SN," each subsequent letter indicates better performance than the previous one. Additionally, engine oils contain additives designed to protect the engine. The further the letter is in the alphabet, the higher the oil grade. Currently, most international brands offer engine oils with grades above SF. Choosing Motorcycle Engine Oil: Today, there are numerous engine oil brands, each offering multiple grades, with gasoline engine oils having nearly dozens of specifications. Consumers should focus on selecting the oil that best suits their vehicle. Higher oil grades are not necessarily better, nor are more expensive options always superior. The most important factor is choosing the right oil for your motorcycle.
