Do you take these safety misunderstandings of cars seriously? (I)

The slower you drive, the safer it is. The speed of the car does affect the safety of driving, but the slower the speed of the car does not mean the safer it is. During the rush hour, the traffic flow reaches its peak. In this case, driving a slow car is simply a disaster. This behavior will not only aggravate congestion, but also easily cause tailgating or other important traffic accidents.

The smaller the deformation of the vehicle, the safer it is. Many vehicles have a large deformation after an impact, such as the front face or rear of the vehicle. This is because the impact force is relieved in the process of deformation after the vehicle is hit, so the driver and passengers in the car can suffer less damage.

Misunderstanding that some car owners always habitually fill up the fuel tank and do not stop when refueling.In fact, too much fuel tank is not conducive to safe driving. Because excess gasoline may overflow, in this case, once it encounters an open fire, it will cause serious consequences and threaten the life of oneself and others.

Among them, downhill idle taxi is a fallacy. This behavior seriously threatens the life and safety of the car owner. All car owners should drive through the downhill section normally according to their usual driving habits, and avoid idling in various road conditions.

4. What are the classifications of car collision safety measures?

1. Passive safety device: airbag, seat belt, safety outlet (automatic) fire extinguishing device, safety glass, child seat, body strength (anti-collision ability), etc. Nowadays, people pay more and more attention to the safety performance of cars, and the safety configuration of cars is also increasing, and the performance is more and more advanced. .

2. Car collision safety is divided into two aspects: active and passive. The so-called passive safety device is a component that plays a buffering and energy-absorbing role when a collision is about to occur, such as bumpers, airbags, seat belts, etc.

3. According to the type of retractor, seat belts can be divided into lockless, manual debugging, self-locking, emergency locking and power-limiting. The main difference is that the retractor is different.

4. ● Volvo's blind spot information system The main safety card has always been Volvo's most important and best field. Therefore, in terms of improving safety design, they also spare no effort to innovate.

5. Completely inelastic collision: Automotive safety design: Completely inelastic collision plays a key role in automotive collision testing and vehicle safety design. In collisions, the vehicle mainly protects passengers by absorbing energy and deformation, so it is necessary to consider the deformation after the collision to improve the safety performance of the vehicle.

Misconception 2: Cars also need to start in second gear and start in second gear. Large trucks and tractors are common, because the main function of these vehicles is heavy transportation, the engine has richer torque, and the second gear starts faster.

The harder the car body, the safer it is. This is a big misunderstanding. Diamonds are the hardest natural substances in the world, but why there are no diamonds as weapons, not because they are expensive, but because they are brittle. The shell of the car is too hard to have a certain cushioning force when it is hit.

The slower the driving, the safer it is. The speed does affect the safety of driving, but the slower the speed does not mean the safer it is. During the rush hour, the traffic flow reaches its peak.In this case, driving a slow car is simply a disaster. This behavior will not only aggravate congestion, but also easily cause tailgating or other important traffic accidents.

But in fact, this is a misunderstanding. Don't forget to cool down. Antifreeze not only plays an antifreeze role in winter, but also cools the engine during driving.

Do you really know these car safety knowledge?

1. From the perspective of ergonomics, the brake pedal and accelerator pedal must have a certain degree of recognition. When stepping on the brake, prevent accidentally stepping on the accelerator to ensure the safety of the people in the car. The brake pedal will be about 20mm higher than the accelerator pedal, which is a little uncomfortable, which plays a role in prompting the driver and preventing the wrong accelerator.

2. Don't keep stepping on the brake when parking: Keep stepping on the brake until the vehicle stops driving will have a relatively large impact in an instant. The skill is to release the brake once before the vehicle stops completely, and then brake gently until the vehicle stops driving.

3. Engine soundproofing cotton is also a topic that everyone is talking about, because you don't need much knowledge to judge. All kinds of sub-factory soundproof cotton are sold overwhelmingly on Taobao, and the quality is uneven.

4. Try not to refuel on thunderstorms, because gasoline is volatile and easy to burn, and a large number of charged particles will be pervasive in the air in thunderstorms. The oil gun is easy to flow charged particles into the car's fuel tank, causing the molecular movement of unstable gasoline to intensify, causing fires, explosions, etc. Safety hazards.

5. In fact, this safety structure is designed for ultra-low-speed collisions.When the speed is slightly higher, the anti-collision beam will have no anti-collision effect. In short, for example, if you accidentally hit the wall when moving the car in the parking lot, this is an ultra-low-speed collision. At most, the paint of the car is scratched. Because the anti-collision beam is on the inside, it will not damage the car body.

6. These life-saving car safety cold knowledge First cold: the brake is higher than the accelerator. In fact, the brake accelerator is not at the same height. In general, the brake is higher than the accelerator. Except for some high-performance cars (sports cars), in order to facilitate the heel movement when braking, the brake is about the same height as the accelerator.
