What happens when the car reaches 120 km h and is in reverse gear?

As for the car, now it is an indispensable means of transportation for every family, it can be said that almost every family has a car of their own, and now, the performance of the car is very good, and there are many safety measures, so it is more and more safe in the car.

However, when I saw this question, I couldn't help but click in to take a look. What happens when a car is in reverse gear at high speeds? I thought about it for a moment and felt that this was probably unlikely.

The first thing is to look at the gear of the car, once it reaches 120 miles, that is, full speed ahead, it should probably be 5th gear. At this time, you are hanging up the reverse gear, if it is a normal situation, that is, there is no safety system, you can hang up, that is, the car will stop and stop in an instant. There will be no sudden retreat and the like, after all, it is the vehicle that has a strong inertia.

However, this situation is not possible at all now, because the current safety system of the vehicle is to say that if you suddenly hang the reverse gear when the vehicle is running fast, it will not take effect, because the safety system stipulates that as long as the car is not stopped or running slowly, it cannot be hung in reverse gear, even if the reverse gear is pressed, it can only be regarded as hanging a gear to deal with.

Moreover, the vehicle is running, if once the reverse gear is hung up, it is estimated that any anti-lock braking system or any ESP and other safety systems will be urgently started, and it will not let you drift like in the movie.

In short, vehicle technology has advanced a lot, and although there will be some mistakes on the part of the driver, the current vehicle safety system will try to protect the safety of the driver and the people in the car. It can only be said that today's cars are getting safer and safer, and the impact of emergencies on vehicles is gradually decreasing.

Many people who don't understand cars think so, they think that when the car is very fast, if the car is in reverse gear, the car will not be directly damaged or even rolled over. Automakers have been thinking about this problem for a long time, and they have effectively prevented it. The people who make cars are those who specialize in the problem of cars, so what we can think of has already been thought of and solved.

Otherwise, so many vehicles in the world are still driving very well, and more and more people are buying cars. Take the manual transmission car as an example, the manual transmission is divided into seven gears, the first gear belongs to the starting gear, followed by the second gear until the sixth gear, each gear corresponds to the corresponding speed, when a car wants to run to 120 kilometers per hour, it is the maximum gear. <>

Then the last gear in the seven gears is the reverse gear, the reverse gear must be very stable after the vehicle can be hung up, so when the car is running fast, it is impossible to hang the reverse gear in, even if the speed is reduced and the gear is forcibly suspended, there will be problems with the occlusion between the gears, damaging the car, I don't think anyone will be so stupid to do the act of damaging the car. In addition, there is an automatic transmission car, this kind of car is definitely more convenient than a manual transmission car, this kind of problem prevention is more perfect, there is no car at high speed when you can also hang into the reverse gear.

In addition, many cars can only be used, and there will be a function called reverse gear lock on it, which means that when the car is not very stable, the reverse gear function is locked, and it is impossible to hang reverse gear. Therefore, the situation that the car drives fast and hangs in reverse gear will not occur, and the car manufacturer will not allow it, and the danger is too great. If you are not careful, you can cause danger to your own business.

Safety first on the driving road, strictly follow the norms of operation and driving, do not blindly mess around.

Introduction: When the car reaches 120 kilometers per hour, suddenly engaging in reverse gear is likely to cause the vehicle to roll over, and some other accidents may occur, because the sudden emergency braking of the vehicle will cause danger in other places such as the steering wheel. When the speed reaches such a high speed, it is not recommended that everyone suddenly scratch it.

First, it is likely to cause a rollover

Drivers should know it, scrape the big knife gear is what kind of behavior, if you say that your speed reached 120 kilometers per hour, suddenly to the gear will only bring a lot of risk, it will cause some more serious consequences, first of all, it is suddenly reverse, it is likely to be like that kind of sudden braking, the vehicle may turn sideways or roll over, in the morning with the slope may also appear such a dangerous situation, so we must not suddenly hang the reverse gear <>

Second, it is very easy to have accidental traffic accidents

And you must know that it will not light up when the reverse brake light is suddenly hung up, and there is no way to remind the rear car in advance, it is likely to cause a more serious rear-end accident, you must know that his speed of 120 kilometers per hour is relatively high, you do not keep a safe distance from others, and the sudden landing is hanging down, but it will only let other people's cars crash into your car, and you will also bear the main responsibility, so we must pay attention to the way when driving. <>

Third, the car was seriously damaged

Suddenly hanging the missing gear, it may also cause the transmission shaft universal joint connecting bolts will be subjected to serious shear force, and may break the shear, because it reduces weight, and most of them will be twisted and deformed when they are empty stars, it may occur to hit the gear, they must control their speed, we don't drive out if there is a quality problem. For the sake of our car, we must not make such an attempt, pay attention to the speed when driving, know where you are, what kind of speed you should drive every hour, do not suddenly change the speed, and do not suddenly go to gear or brake.

There will be a situation of overturning, or it will cause an accident, and the respondent will also have an unexpected situation, which will lead to the situation that the speed of the car is unstable, or there will be a problem of system failure, and it will also cause the car to reverse quickly.

The car will slow down, and it will also have a serious impact on the car's start, and the damage is also relatively high.

The car suddenly braked, the engine ran violently, and the ground was rubbed with white smoke due to the lead and hidden tires, and the body began to be uncontrolled, and there was an offset, which was very prone to traffic accidents.

It can cause the engine to stop suddenly, damage the gearbox of the variable sail, and also damage the gears of the gearbox. Sensitive to severe wear and tear of the vehicle. It will also cause the vehicle to brake suddenly or fail to close the brakes.

The maximum speed of the general car reverse gear can reach 70 kilometers per hour; The off-road vehicle has a speed of 80 kilometers per hour; And the big loan car is 50 kilometers. Generally speaking, the reverse gear of civilian cars can only be driven to about 40-60 yards, mainly because the manufacturer has been set, the speed ratio of the reverse gear is equivalent to the speed ratio of the first gear, and the speed ratio is not a fixed number, which is related to the speed ratio of each car, basically most of the vehicles 1 gear speed ratio is around, if the maximum speed of the vehicle is assumed to be 5000-6000rpm, then the speed of the vehicle can be calculated to be about 51 kilometers.

How fast you can drive in reverse gear, I know how fast the car emperor has tested on the track before. Mercedes-Benz C260L reverses at full throttle and drives to about 4200rpm before the fuel is cut off, and the corresponding speed is 37km h. Judging from this gear ratio, the theoretical maximum speed of this car (6250rpm to the red line) should be about 55km h, and it is obvious that the manufacturer's calibration is much more conservative.

As long as the speed of the reverse gear is based on the speed of the vehicle and the transmission ratio of the first gear and the reverse gear, you will know how many kilometers it will take, for example, the maximum speed of the car reverse gear is 45, and the fastest forward is 225, if it is an ordinary car, the fastest reverse is 33, and the forward is 205.

The top speed can reach 120 km/h. Therefore, when the car is engaged in reverse gear, the speed is still very fast. But it's not the fastest either.

The top speed can reach 100 kilometers per hour, which is considered speeding on most roads, so be careful.

What happens when the car reaches 120 km/h and suddenly engages in reverse?

Traveling at 120 km/h, can you engage in reverse?

In this case, when the vehicle is driving at 120 kilometers per hour, if it is artificially forced into reverse gear, it is very difficult and impossible to complete. In the previous manual transmission vehicles, because the gearbox does not have the protection design of the speed range of the gear, it is impossible to suddenly hang into the reverse gear at a speed of 120 kilometers per hour only by relying on the guide angle on the transmission gear in the gearbox. This can only cause the gears in the gearbox to rattle and not to engage in reverse gear, because there is a speed difference between the gears in the gearbox.

Today's manual transmissions are designed to protect the gears for speed, so even if you push and pull the gear lever to the reverse position, the vehicle will still continue to drive in the original speed gear. The push-pull stop lever in place is just an illusion. This is not even more true for intelligent automatic vehicles.

That is to say, the current automatic transmission vehicles are controlled by the computer in the speed range of each gear, and the forced shift behavior of people, as long as it does not conform to the logic of the speed range of the empty gear, the computer will not execute, so that it can not carry out tough gear shifting behavior.

What would happen if you really suddenly got into reverse gear at 120kmh?

Here we can only assume that at 120km h, the reverse gear behavior is suddenly hooked, and what are the consequences of this happening? In this case, when the vehicle is driving at 120kmh, the inertia under the acceleration of gravity will cause great damage to the vehicle.

The rear axle reducer gear will have a serious toothing behavior.

The connecting bolts of the universal joint of the transmission shaft will be subjected to severe shear force and may break and shear.

The propeller shaft, which is mostly hollow due to weight reduction, will be twisted and deformed.

The gears of the gearbox will be hit by a strong impact, and the phenomenon of gear beating will occur.

The clutch plate is severely ablated or smashed to pieces due to the huge speed difference.

If the vehicle is traveling at 120 km/h, it will cause a phenomenon similar to sudden braking. The vehicle may turn around, roll over, and if it is downhill, it may be extremely dangerous.

The driver will suddenly hit the steering wheel or other places due to the vehicle's sudden braking behavior, such as the use of seat belts may fly out of the car.

8.Because it is suddenly engaged in reverse gear, the brake light will not be on and warn the rear car in advance, which may cause a serious rear-end accident.

It should be noted that our manual transmission vehicles may be forced into reverse gear at a speed of 10km h or 20km h, so please do not try it for the sake of your car and safety.

Yes, because I think this kind of behavior is still quite harmful to the car, try not to do this.

It can cause damage to the transmission of the car. We must not engage in reverse gear at high speeds. This will affect driving safety.

It's definitely going to damage the car. This practice can cause the car's gearbox to be damaged and cause the car to have an accident.

Cars are moving at high speeds, and with speed comes danger, so cars are also highly dangerous objects. Moreover, the correct operation of the car at high speeds is crucial.

However, curiosity is in everyone's nature, and some people have crazy ideas about what would happen if the car reached 120 kilometers per hour and suddenly engaged in reverse. Don't believe it, there was a guy in the United States who did this crazy thing before, and he was driving an automatic car. He increased his net speed to 120 km/h before suddenly putting on the reverse ......

However, the imaginary dangerous thing did not happen, after the car was hung up in reverse, the reversing image was shown, but the car's reaction was in a neutral state, there was no power and no abnormal noise, in fact, the current car, especially the automatic transmission model has a gearbox protection function, the purpose is to be afraid of the driver.

Misoperation and accident occurred when hanging on the reverse gear.

But for the manual transmission model, it is still different, that is, in the state of driving forward at low speed, it can be engaged in reverse gear, and then you will hear the friction sound of the gearbox gears, which will be fatal to the gearbox. If you are in a high-speed situation, such as at 120 km/h, it is difficult to get in, even if you step on the clutch.

Today's cars are smarter, and even manual transmission models have a "reverse gear lock" function. Before you put into reverse gear, the system will check your speed, which is actually to see if you have stopped. You can only engage reverse gear when the car is parked, otherwise you won't be able to hook up anyway.

As for the automatic transmission, it is even more intelligent, and the automatic transmission will be calculated by the intelligent computer in advance to see if it conforms to the logic of shifting. When driving at 120 km/h, if you are in R gear (reverse), the intelligent computer thinks that this does not conform to the logic of driving and gearing, even if your gear lever is hung on the reverse gear, in fact, it will not let the gearbox execute the gear command.
