Parking for a long time the handbrake is still not pulled

I don't know if my friends have such a habit: even if you drive an automatic car, you don't bother to pull the handbrake when parking on a flat place, and you don't think it's necessary.

Is it really okay to park only in P gear and not pull the handbrake? Let's talk about it today:

Let's park the car on flat ground, and there is really no big problem if we don't pull the handbrake.

However, let's say we park our car in a place with a slight slope, or when we park, we hit the curb of the road, the limiter in the parking space, etc. At the time, I didn't feel anything, and the gearbox didn't feel uncomfortable pushing into P gear.

But when you want to start the next day and pull out of the P gear, you will find that it is a bit difficult, and there will be a "pop" sound when you pull hard. Why is that?

Because the parking pawls and locking wheels of the gearbox are competing with each other.

We don't have to worry too much about this occasionally, but if you park like this often, there will be problems! The locking structure of the gearbox may be damaged, and it may not be possible to hook it from P to another gear in serious cases.

Therefore, when you park, try to park your car on a relatively flat road, and do not stand against the road or the limiter in the parking space.

The right way to park your car.

When parking, you should pay attention to the fact that if the tires are against the curb or the limit lever of the parking space, it can be like this

Hang N gear - release the foot brake (for unloading) - pull the handbrake - hang P gear - turn off.

This way, there will be no situation where it is difficult to pull out of the P gear at the start!

If it's time to park on a ramp, that's what you should do:

Hang N gear - tighten the handbrake - release the foot brake - hang P gear - turn off.

Having said all this, everyone should also understand the disadvantages of only hanging the P gear and not pulling the handbrake.

So please develop a good habit of pulling the handbrake after parking, especially when parking on a ramp. Pulling the handbrake can also avoid rolling accidents.

Avoid roll-over accidents.

Precautions for pulling the handbrake.

It's not good to pull the handbrake so tightly!

It is also best not to pull the handbrake on the ramp for a long time to stop, which will also cause the handbrake cable to wear. If you really need to stop on the ramp for a long time, you can pull on the handbrake and put a brick on the side towards the bottom of the slope to fix it to reduce the pressure on the handbrake!

Si Youpu said that the car summarized whether the handbrake should be pulled up for a long time of parking.

As we all know, the gears of automatic transmission models have P, R, N and D, and there is a difference between P and N. The P gear is fixed to the transmission with a mechanical lock, and the N gear can be moved at will. Some models can't pull out the key when the N gear is hung.

Normally, the gear is hung on the handle brake in the P gear, which guarantees that the vehicle will not slip on the slope even without the handle brake. Automatic transmissions are generally divided into four gears: P, R, N, and D, and some transmissions have S, M, and L modes. The so-called S mode is the sport mode of the car.

The reason why it's a mode, not a gear, is because from the mechanics of the gearbox, both S and M are essentially in D gear. The difference is that the shift logic is different. In S mode, the gearbox downshifts more aggressively while delaying upshift opportunities.

Using the large transmission ratio of the low gear of the gearbox, it can output large torque and high power, and improve the dynamic response of the car. In addition, some models have a uniform SM mode, which allows manual shifts to be restricted.

Parking is a parking gear. When the parking is not in use, the gear is here, and the wheels are mechanically locked to prevent skidding. Handbrake, technically known as secondary braking, differs from the braking principle in that it is connected to the rear brake shoe with a steel wire to brake the car.

If the driver drives an automatic transmission car at the intersection and encounters a red light, and does not pull the handbrake and directly hangs the P gear and other red lights, then a car behind suddenly rushes to the rear end. The carrier of this impact force is the gears of the gearbox, and the gears in the gearbox cannot be rotated at this time, so this huge impact force is likely to cause the gearbox to be scrapped directly. If the vehicle is parked on a half-slope, first hang the P gear, the carrier of the vehicle's downhill force is the gearbox, but if the handbrake is pulled first, the carrier is the braking system, and the existence of the braking system plays such a role.

That's why some drivers may say that the brake pads are badly worn. If you think about it carefully, which is more expensive, gearbox or brake pads, needless to say, everyone knows it in their hearts. Automatics can turn off and pull the handbrake in N and P gears.

However, the key can only be pulled out in the P position. In the n gear, the transmission gears are separated, and in the P gear, the gears are combined. Therefore, on the road with slopes, the brakes must be pulled when the N gear is turned off, otherwise the car will slip, and the P gear will not.

But at the same time, it should be noted that even if the P gear is parked on a flat road, you need to pull the handbrake before getting out of the car and leaving, otherwise the vehicle may still move due to the coupling force.

If you care about the gearbox, it is recommended that you turn off the ignition and slow down to stop the car as follows; Hang N gear, pull the handbrake, turn off; Hang up the P gear and pull out the key. The advantage of this is that the gears are separated in N gear and merged in P gear. If the engine stalls in P gear and the road surface is uneven, it will have a certain impact on the gear.

Hang N gear and then P gear to protect the gearbox. When starting, turning the gear lever to N gear and ignition again can also avoid the extra impact on the gear when the gear lever passes through R gear.

If you don't pull the handbrake after parking, then there will really be a rollover, which is likely to cause an accident, and the consequences are very serious, so you must pay attention.

Mainly because if you don't pull the handbrake on a slope, the car will slide down on its own.

Because the road is uneven, the handbrake is to fix the car, and in different environments, not pulling the handbrake may cause the car to move, resulting in losses.

Because this is an effective way to prevent rolling, if you park in a flat place, the car is likely to slip down the slope due to the weight.

It is recommended that you turn on the autohold state for a long time, the correct way is to get on the car and fasten the seat belt, press the autohold switch, the position of this switch is known, under the gear handle, after the light is on, the automatic parking is turned on, so that you can directly hang the p gear, after the seat belt is released, the p parking light is on, the automatic parking starts, and you can directly stop and leave; Auto-station.

In theory, it is recommended to tighten the handbrake in any case of parking. Because the handbrake is prepared for parking, the car will not move due to external force only when the handbrake is tightened.

For example, if there is a slope where the vehicle is parked, if the handbrake is not applied, the vehicle will roll due to inertia.

Even if you are parked on flat ground, it is recommended to tighten the handbrake. Here are a few examples:

1. There are some naughty children who are likely to push the cart when they know that the vehicle does not pull the handbrake. 2. If another car hits your car, the vehicle will move because the handbrake is not pulled.

However, it should be noted that for non-electronic handbrakes, pulling up 100% of the force for a long time will shorten the life of the handbrake cable.

Because after the handbrake is tightened, the handbrake cable is in a tight state, and it is easy to cause the plastic deformation of the handbrake cable to be irrecoverable after a long time, which increases the load of the handbrake cable, which will eventually lead to the relaxation of the handbrake cable.

But changing the handbrake cable is cheap and doesn't cost much. So the summary is:

When parking on the flat ground, the handbrake does not need to be pulled very tightly. When stopping on a ramp, the handbrake must be tightened.

In addition, you can hang 1st gear on uphill slopes and reverse gear on downhill slopes, and use the gear position to prevent rolling. Together with the handbrake, it plays a double insurance.

Theoretically, it is advisable to tighten the handbrake whenever you stop. Because the handbrake is prepared for parking, only by tightening the handbrake will the car not move due to external force.

For example, there is a ramp where the vehicle is parked, and if the handbrake is not applied, the vehicle will skid due to inertia.

Even if you are parked on flat ground, it is advisable to tighten the handbrake. A few examples:

1.There are some naughty kids who, knowing that the vehicle does not have a handbrake, are likely to go for the cart. 2.If another car crashes into your own car, the car will move without a handbrake.

However, it should be noted that if the non-electronic handbrake is pulled up 100% for a long time, the service life of the handbrake cable will be shortened.

Because after the handbrake is tightened, the handbrake cable is in a tense state, and the plastic deformation of the handbrake cable is irreversible after a long time, which increases the load of the handbrake cable, and eventually leads to the relaxation of the handbrake cable.

But changing the brake line is cheap and doesn't cost much. So the summary is:

When parking on flat ground, there is no need to tighten the handbrake. When parking on a ramp, the handbrake must be tightened.

In addition, you can hang a first gear uphill, and you can hang a reverse gear on a downhill slope, and the gear can prevent the car from skidding. Use the handbrake to make a double safe.
