Why do you sometimes see a flag with a very long flagpole mounted on the back of an off road racer?

Personal habits or for markingFor example, in the desert or a special place, you can better let others know where you are.

Off-road sand, as a beginner in addition to the practice of driving skills, there are a few confusions in the early stage is that sometimes busy looking at the road, when encountering the hard sand surface or the rutted chaotic ground, the distance from the front car is large, and the car in front does not know where to go and gets lost, or is shuttling in the sandbag, the front car is also easy to get lost by the sandbag, and the flagpole installed on the car provides great convenience to the rear car! Now there are many ways to hang a flag on the flagpole when the sand is open, some hang a flag on the ceiling vehicle antenna, some tie a stick on the car, and some temporarily tie a fishing rod on the car, all kinds of ways are available, and the convoy is spectacular and easy to identify when walking.

In order to make the flagpole convenient and beautiful, I have seen a lot on the Internet, and using a fishing rod as a flagpole is the most economical, convenient and practical way. After sorting out the information, start to make your own, first buy two vehicle antenna splints through online shopping for a total of 70 yuan (including postage), go to the building materials store to buy 2 conical grinding wheels for 8 yuan (to prevent personal damage and then go to the building materials store), fishing tackle shop to buy a 7 meters 2 fishing rod, do not want the brand and do not want the softness, as long as the ** shaft is hard to spend 60 yuan, at home ready to put the electric drill, roll fluorescent confession, a 5-cent coin on the material is complete!

Off-road sand sharps production, standard flagpole materials and production technology.

1. Material: The main material of the flagpole is the polished and welded stainless steel engineering pipe of different thicknesses of the international 1Cr13, the interpolation reinforcing pipe adopts different specifications of national standard steel pipe, and the connecting flange adopts ordinary A3 steel.

Second, the production process.

1. Connection of the flagpole:

1) The flagpole is made of several stainless steel welded pipes of different specifications, with reinforced steel pipes inserted and welded through flanges.

2) The inner circle of the flange and the flagpole is transitioned together, and the tolerance is positive and negative.

2. Production requirements:

1) The surface of the rod shall not be damaged during the production process, and the welding place shall be polished and polished.

2) After welding around the rope frame and the upper pulley, it should be in the same plane through the axis of the flagpole.

3) The company's sign is spot welded at a height of 800 above the ground under the rope frame.

Off-road vehicles are often used to go to more remote and desolate places, and the addition of flags can be more visible.

Because the car is relatively low, it is easier to spot it with a long flag, and it is easier to distinguish between the cars.

Because off-road racing cars are generally fast, planting a long flag can make it easy for the vehicle behind to spot him, thus keeping a safe distance.

This kind of pool will look more obvious, and it will be easier to spot in the event of an accident.

A very long flag is installed on the off-road vehicle to make it look more visible.

Once you enter the desert, or the cool off-road area, enter the deep ditch or rugged section, the vehicles behind you can't see your car, but they can see your flag flying high, so as to avoid some unnecessary trouble, after all, when you go off-road, prevent the rear car or other directions of the car to know your situation, you can't light the wolf smoke, or put fireworks signals like a martial arts movie, and then the flag is particularly important.

The installation of a high flagpole on the car provides great convenience for the rear car.

If something goes wrong, it is easier to be rescued, there is a little more chance of help, and there is more hope for survival.

Planting a long flag makes it easy for vehicles behind to spot him, thus keeping a safe distance.

...The racing car is also a car, and there is no big structural difference between the racing car and the ordinary car, which is basically a dao

The difference in parameters goes back to for example: the suspension is stiffer, the aerodynamics are better, the compression ratio of the engine is larger, the gear ratio of the gearbox is more reasonable, or something.

The biggest difference is in the way you drive.

Normally, driving to 4000 is a relatively high rev, but the car will use the rev to the red line. Civilians will drive more strictly according to the rules of the road on the corner, but the car will seek the fastest corner route on the track.

If you don't understand, you can refer to a ** - Hurricane

Not badly written in terms of getting started.

The difference is that the accessories of the racing car are born for performance Generally, the engine will be scrapped or overhauled after a race, and the civilian car will not be used In fact, most of the racing cars are modified from civilian cars Few cars are redesigned for the competition Just modify the car The WRC of the year stipulated that the participating vehicles must have 25 quantities of production Since the energy is produced, it means that the racing car is also modified from the civilian car.

There is no difference in the overall structure, they are all cars, but the performance is not the same.

The simplest and purest difference.

Cars are much more handsome than cars.

The cars we are talking about now, in fact, are actually civilian cars, and they are only for civilian production cars, and even the production cars of EVO are different from professional racing cars.

Professional racing cars are born for speed, and even in terms of basic technologies such as body rigidity, they are incomparable to civilian cars.

The mission of the car is to be faster, more stable, every inch of its shape is to reduce wind resistance while increasing downforce, the whole car has nothing to do with the performance of things, lightweight to do it, such as no weight limit, but also lighter, the various parts of the car are only considered a few games, do not consider the long-term life, such as the F1 engine only, there is about 800 output power, 0 100 kilometers of acceleration seconds or so, and it is air-cooled, because fast, so there is a lot of air flowing through the engine, Better than water cooling.

A car must be a car A car doesn't have to be a race car! Hahahahaha.

The engine performance of the family car is definitely not as good as the racing car, one is to focus on practicality and comfort, and the other is to focus on speed and driving, so the chassis suspension and operating system of the two are somewhat different, not to mention the engine, the body of the latter is lighter than the former. In terms of safety, I personally believe that the safety of sedans should be high, but it mainly depends on driving skills.
