Why do some automatic cars have no handbrake?

It's not that there is no handbrake.

And the handbrake with P gear.

Linkage. That is, automatic parking.

System. This type of car has an automatic manual button, which means to turn on automatic parking or turn off automatic parking. After turning off automatic parking, you need to manually operate the parking, that is, the handbrake.

This is common in higher-end cars.

In this way, you can avoid the problem of forgetting the handbrake. If you forget the handbrake when parking, causing the vehicle to landslide, or forgetting the handbrake when driving, resulting in brake wear.

Generally, there are handbrakes, but the installation positions are different, and some are electronic handbrakes with buttons.

Virtually all vehicles have a handbrake, and there is no such thing as a car without a handbrake. It's just that their handbrakes are different from your usual handbrakes in shape or position.

Or an electronic parking brake!

This is your own loneliness, automatic cars are all handbrakes. It's just that the automatic handbrake may be an electronic handbrake.

Now it is impossible for a motor vehicle to be without a handbrake, and a vehicle without a handbrake cannot be produced.

The handbrake of an automatic car is likely to be electronic, or has a foot brake.

The parking brake, generally known as the handbrake, is used to give the car a resistance when parking, so that the car does not slip. The parking brake, i.e. the handbrake or parking gear in an automatic transmission, locks the propeller shaft or the rear wheels.

The parking brake is much, much less powerful than the service brake, and it is enough to stop on the slope without slipping.

There are different types of parking brakes, and in addition to the mechanical mechanism operated by hand or foot, high-end cars are also gradually adopting electronically controlled parking systems, commonly known as electronic parking brakes.

Electronic Parking Brake (EPB:

electrical

Parkbrake) refers to the technology that integrates the temporary braking function during driving and the long-term braking function after parking, and realizes the parking brake by electronic control. The electronic handbrake is a technology that realizes the parking brake by electronic control, and its working principle is the same as that of the mechanical handbrake, which is achieved by the friction generated by the brake disc and the brake pad to control the parking brake, but the control mode has changed from the previous mechanical handbrake lever to an electronic button.

The electronic parking brake extends from the basic parking function to the automatic parking function AUTO

The use of HOLD automatic parking function technology allows the driver to brake for a long time when the vehicle is stopped. When the automatic electronic parking brake is activated, unnecessary coasting of the vehicle can be avoided, simply put, the vehicle will not slip behind.

The traditional handbrake needs to rely on the driver to start comfortably by manually releasing the handbrake or skillfully throttle and clutch cooperation when starting on a slope. And auto

The HOLD automatic parking function gives accurate parking force by the controller through the slope sensor, and when starting, the parking control unit automatically releases the parking brake when the driving force is greater than the driving resistance through calculation, so that the car can start smoothly. Even if you usually drive in the city, as long as you enable auto

hold function, the corresponding automatic parking function will be activated. Smart auto

The HOLD auto-park function allows the car to automatically activate the four-wheel brake when waiting for a red light or stopping uphill or downhill, even in D or N gear, you don't need to keep your foot on the brakes or use the handbrake, the car is always stationary. When it is time to release the standstill state, you can also release the brake with a simple tap of the accelerator. This configuration is really practical for those car owners who often stop and go in the city, and it also reduces some unnecessary accidents caused by everyone's carelessness.

So what you say about automatic vehicles not having a handbrake is just a misunderstanding caused by not knowing enough about the type of hand brake.

The normal handbrake is divided into nine gears, and when pulled to the largest nine gears, the car is in a passive shutdown state and cannot be driven.

If you can still drive under the handbrake mode, it may be due to the following reasons:

1. The handbrake is lower than the ninth gear.

2. It may be that the brakes can be used for a long time in the state of nine gears, the brake pads are seriously worn, and the brake function is damaged.

The hazards of not letting go of the handbrake to drive:

1. The most direct damage to the car when the handbrake is turned on is the wear and tear of the brake pads and wheels.

2. In the case of a relatively tight handbrake, you can smell the smell of burning, and the brake is easy to fail at high temperatures.

3. If you pull the handbrake for a long time to drive, it may also lead to the brake cylinder biting, brake fluid leakage, and the brake fluid temperature is too high, resulting in the complete loss of brake function.

If you travel a long distance with a handbrake, it is best to go to the after-sales service to check the damage to the brake pads.

Automatic transmission cars also have handbrakes, most automatic transmission car handbrake position and manual transmission car handbrake position is the same, a small number of automatic transmission car handbrake (parking brake) in the lower left of the steering wheel, manual transmission car clutch position upper left, is pedaled with the foot, step on it to tighten, and then step on it to relax.

Hello. It's an automatic handbrake.

As long as the car is stopped, the automatic handbrake takes effect.

Hang D gear and step on the accelerator to automatically release.

Automatic cars also have a handbrake. It's just that the mid-to-high-end car is an electronic parking brake!

Summary. There must be an impact, generally the handbrake needs to be pulled when parking, for example:

Directly hang the P gear without pulling the handbrake and other red lights, at this time there is a car in the rear suddenly rushed over to rear-end, the bearer of this impact force is the gears of the gearbox, and at this time the gears in the gearbox can not be rotated, then this huge impact force is likely to cause the gearbox to be scrapped directly.

Does it have an impact on automatic transmission parking without pulling the electronic parking brake.

There must be an impact, the general handbrake needs to be pulled when parking, for example: directly hang the p gear without pulling the handbrake and other red lights, at this time there is a car in the rear suddenly rushed over to rear-end, the bearer of this impact force is the gears of the gearbox, and at this time the gears in the gearbox can not be rotated, then this huge impact force is likely to lead to the gearbox directly scrapped.

I bought the car for a year, and it has been parked without pulling the handbrake.

There were no accidents, the general flat road is fine, for safety reasons, and you must remember to pull the handbrake on the slope.

I would like to ask why there is a hot air blowing out of the car when the air conditioner is not turned on during driving.

You've started the outer loop. The reason is that the outside air temperature itself is high, and the heat emitted from the engine compartment is blown into the car, so there is a phenomenon of hot air. When the internal circulation is turned on, it is equivalent to preventing air from entering the car, so the hot air disappears.

Automatic cars without a handbrake can apply the footbrake. The professional name of the handbrake is the auxiliary brake, which is different from the principle of the brake, which is connected to the rear brake shoe by a steel wire cable to brake the car. In addition to the handbrake and foot brake for automatic transmission vehicles, some high-end Sanshizhen models have used electronic parking brakes (automatic parking function auto hold).

Automatic foot brake activation method:

1. When starting, you should first step on the brake with your right foot, and at the same time switch the gearbox to the N gear position and start the engine;

2. When the engine starts, press the parking foot brake again with the left foot, and the parking brake will be released at this time, and the parking foot brake will return to its original position under the action of spring force;

3. Switch the gearbox gear from N gear to forward gear (D), and slowly release the brake, then the vehicle can drive in front of Tanshi.

The owner needs to step on the brake first, and then go to hang neutral, if there is no handbrake, the automatic transmission car is generally a push-button electronic handbrake, press the electronic handbrake after hanging neutral, and then go to hang P gear, and finally turn off. If the ignition is turned off directly in the P gear, as long as the vehicle is in a ramp state, it is easy to cause wear and tear on the gears of the gearbox, resulting in unnecessary trouble.

If you do not operate in the correct way during the process of driving the automatic transmission car, you can directly choose to hang the P gear to turn off. As long as the vehicle is on a ramp, this causes contact between the parking pawls and the gearbox parking gears. For a long time, the gearbox parking gear and the parking pawls will be severely worn, causing problems in the vehicle in advance.

Due to the different automatic transmission models, the handbrake control methods are different, as follows:

1. The traditional hand coarse combustion brake is generally in the drooping position on the right hand side of the driving rock operator, pulling up is the brake, after holding the button, the handbrake is put down to indicate that the brake is released.

2. Electronic handbrake, many automatic models now use electronic handbrake, the operation mode is very simple, that is, directly use a button, so as to turn on or off the function of the handbrake.

1.When pulling the handbrake to drive for a long time, the most direct damage is the wear and tear of the handbrake, and when the handbrake is pulled, the pressure of the handbrake is not constant, it will change with the speed, speed bumps, and even the collision of obstacles, that is to say, in the process of driving, the handbrake constantly accepts large and small losses.

2.If you pull the handbrake to drive for a long time, it may also lead to the brake cylinder biting, brake fluid leakage, and the brake fluid temperature is too high, resulting in the complete loss of brake function, which is a very dangerous thing on the way.

3.In the unlikely event of a severe burnt smell and smoke coming from the rear of the vehicle, the owner should immediately slow down, brake, and lower the handbrake.

Hello, the hand brake is the parking brake, that is, the parking brake, the car with strong power and horsepower can also drive away without letting go of the handbrake, or the big foot accelerator can also be. This is a misoperation, after the brake brake is normal and damaged in advance, and it is very fuel-intensive. Good luck with your car!
