What happens if you don t pull the handbrake when you hang the P gear, and if you stop for a long ti

Slip away.

The handbrake is not pulled when the P gear is hung on the flat road: the vehicle will not slip on the flat road, and the gearbox is not in the stressed state, so there is no harm in the P gear (parking gear).

The ramp is hung with P gear and does not pull the handbrake: the ramp must be hung with P gear, but it is not enough to hang P gear, at this time the internal parts of the gearbox are still in a state of stress, and it is best to pull the handbrake again to get double protection.

Correct parking method with P gear.

The correct parking steps for automatic transmission cars are: after the car enters the parking space, first step on the brake and hang N gear, then pull up the handbrake, then release the foot brake and turn off, and finally hang the P gear and pull out the key. The gear holding method of the automatic transmission car:

Brake - Ignition - Gear (P to D) - Release the handbrake - Raise the foot brake - Fuel - Start.

Correct method: turn on the power first (do not hit the engine) - step on the brake and hang the gear, not directly into the D gear, but hang on the N gear and then ignition, and then hang from the N gear to the D gear, release the handbrake, lift the foot brake, and start.

It won't be good,AutomaticParking directly on the P gear, without pulling the handbrake, in most cases, the car can be parked steadily, and it will not be damagedGearbox

Automatic. The P gear is generally composed of parking pawls (hooks), parking gears (wheels with slots on the outer edge) and some accessories. The parking gear is fixed to the automatic transmission.

On the output shaft (some models are fixed to the housing of the differential), it rotates with the operation of the car; The parking pawl is attached to the shell of the automatic transmission, which is equivalent to the body of the car.

When the driver stops the gear into P, the lever pushes the pawl into the card slot of the parking gear. At this moment, the parking gear passes the action of the card groove and the pawl, and then through the hinged action of the other end of the pawl and the transmission housing, which is equivalent to the parking gear and the gearbox housing are fixed together, and the parking gear is connected with the differential, half shaft and wheel.

In this way, the wheels and the gearbox housing are fixed together, and the wheels cannot be moved, thus stopping the car. When starting the car, the driver releases the P-gear lever, and the pawl leaves the parking gear slot under the action of the return spring, and the parking gear can rotate freely.

If the driver drives an automatic transmission car and encounters a red light at the intersection, he directly hangs the P gear without pulling the handbrake and other red lightsAt this time, there is a car in the rear suddenly rushed over and rear-ended, 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, so this huge impact force is likely to cause the gearbox to be scrapped directly.

Precautions. If the vehicle stops on the half-slope and first hangs the P gear, the bearer of the vehicle's downhill force is the gearbox, but if the handbrake is pulled first, this bearer is the braking system, and the existence of the braking system plays such a role.

If you hang the P gear, you won't pull the hand brake and won't slip. If it is a long time to park, it is better to pull on the handbrake. In fact, the P gear structure is that there is a gear on the output shaft, and there is a hook next to the gear, and the hook will hook the gear when it is hung to the P gear, so as to lock the output shaft.

In other words, the drive wheel cannot be rotated in P mode. In other words, hanging the P gear is actually a "hook" for the transmission"to hook a part of the output of the transmission.

The correct operation of the automatic transmission and the P gear is:1. After confirming that the car is stopped, hang the N gear to pull the handbrake, turn off the engine, and hang the P gear;

2. The reason why the N gear is hung first, the handbrake is then hung after the P gear is suspended, the gear is still in the D gear, the engine does not completely stop running, or it will give the car a part of the power, at this time, the N gear will become neutral, and the engine will stop providing power;

3. After pulling up the handbrake, there is only one power of the wheel, and then hang the gear to the P gear, which will reduce the pressure on the gearbox and brake pads and prolong their service life.

What happens if the automatic transmission is parked and hung in P gear without pulling the handbrake? If it's flat, it's okay, the car won't move without external force, basic safety, if it's a slope, it's quite dangerous to hang the P gear without pulling the handbrake, the consequence is to cause the car to slip, the longer the slope, the more dangerous, you think the car is in an unmanned state. In this case, in the event of any liability accident, the owner will be fully responsible.

So be sure to develop a good driving habit, cultivate it into a habitual action, and pull the handbrake immediately after parking

1. The flat road hangs the P gear without pulling the handbrake.

The vehicle will not roll on the flat road, and the gearbox is not in a stressed state, so there is no harm in wearing the P gear (parking gear).

2. The ramp hangs the P gear and does not pull the handbrake.

The ramp must be hung with P gear, but it is not enough to hang P gear, at this time the internal parts of the gearbox are still in a state of stress, and it is best to pull the handbrake again to get double protection.

Expand. In addition to putting the transmission in neutral mode to work, the P gear is also equipped with a pawl inside the gearbox to buckle the gears on the output shaft to form a mechanical lock, so as to jam the drive wheel shaft to fix the stationary or micro motion vehicle.

The P gear is equivalent to N+ (neutral gear plus handbrake), which can replace the vehicle braking when the handbrake fails to prevent the vehicle from rolling. However, on the ramp, it is best to use the P gear plus the handbrake to stop, so as to prevent the load of the P gear from being caused by long-term parking, and pulling the handbrake is equivalent to double insurance is safer. And the handbrake should be pulled first and then put into the P gear, which can damage the gears for a long time.

If you don't pull the handbrake when you park in automatic transmission, will relying only on P gear damage the gearbox? Can I park my car?

It is not possible to park for a long time and hang the P gear, without pulling the handbrake. For cars with automatic transmission, after parking, the gear lever should be put in P gear, the parking brake (handbrake) should be activated, and then the engine should be turned off.

However, the gear lever is placed in P gear, only the automatic transmission is locked, and there is still a potential safety hazard of slipping when parking is parked in a sloped place, and only by enabling the parking brake (hand brake) to lock the car braking system can the car not slip. In order to ensure the safe parking of the vehicle, the handbrake should be applied.

Flat roads can be carried as long as the P gear is attached, but doing so on a sloped road will damage the gear lock, and if it is on a steep slope, it may directly damage the gear lock.

Putting the P gear without pulling the handbrake will be harmful to the gearbox.

First of all, when using P gear to park, the car's gear device will directly hook the gears of the gearbox, so that the gearbox will directly stop the output, that is, it is equivalent to locking the driving wheel of the gearbox, so that the car lacks the drive, and it will naturally stop directly. However, if you stop for a long time, most of the resistance to parking comes from the gearbox.

In the long run, there is a risk that the life of the transmission lock-up device will be shortened. Especially when parked on the ramp, the harm to the gearbox will be greater, and in such a state when the car is parked, when we start at low speed again, it is relatively difficult for the car to start, and even some noise can be heard, which also indicates that our car gearbox is slowly damaged.

But what exactly is the right step to stop? For the correct parking steps of automatic transmission, that is, you must first step on the brake, then hang neutral gear, then pull the handbrake, then hang the p gear, and finally turn off the engine, this is the parking mode of the correct automatic transmission car, if you pull the handbrake, you can also transfer the main force of parking to the brake device, so that the gearbox of the car can be protected to the greatest extent.

However, there are some people who feel that the impact of hanging to the P gear on the gearbox is relatively small, and it is not as serious as it is said, but the gearbox of the car is also very important for the car, and its importance is self-evident, but when your gearbox is really damaged, it may have passed, and the days of running to the maintenance plant at two ends in three days, and the gearbox of the car must be replaced before you can continue to walk.

Hanging the P gear without pulling the handbrake can easily cause the situation of slipping.

If driving on the ramp, without pulling the handbrake, it will lead to the gravity of the vehicle sliding, all of which are borne by the gearbox parking mechanism, which will cause damage to the gearbox, if the situation is serious, it may also make the gearbox directly scrapped, and the P gear and handbrake should be reasonably applied.

When the vehicle is in the P gear, the parking locking mechanism will lock the output shaft of the transmission, which means that the gears in the gearbox cannot be rotated when the P gear is in the P gear. When parking in P gear, the car's gear device will also directly hook the gears of the gearbox.

In this way, the gearbox will directly stop the output, that is, it is equivalent to locking the driving wheels of the gearbox, so that the car lacks a drive, and it will naturally stop directly. However, if the car is parked for a long time, the resistance to the parking of the sail part also comes from the gearbox, which may shorten the life of the gearbox locking device in the long run.

The main purpose of the P file:

The P gear is a special neutral gear that is used to fix the hand fiber vehicle by mechanically locking the output shaft of the transmission, and its function is to brake after stopping to prevent the vehicle from moving. Bi bent imitation.

For the sake of practical safety, automobile manufacturers place the P gear in the first position of the gear shift console, and force the car key to be pulled out only by moving the shift lever to the P gear through the internal mechanism setting. Therefore, the P gear is a gear dedicated to parking for a long time in an automatic car.

For example, let's illustrate what the consequences of not pulling the handbrake when parking in P gear:

If the driver drives an automatic transmission car at the intersection and encounters a red light, directly hang the P gear without pulling the handbrake and other red lights, at this time there is a car behind the car suddenly rushed over to the rear-end town to kill, the bearer of the impact force is the gears of the gearbox, and at this time the gear bridge in the gearbox can not be rotated, then this huge impact force is likely to cause the gearbox to be scrapped directly.

Same as above, if the vehicle stops on the half-slope and first hangs the P gear, the bearer of the vehicle's downhill force is the gearbox, but if the handbrake is pulled first, this bearer is the braking system, and the existence of the braking system plays such a role.

This is what some drivers may say, so that the wear of the brake pads will be very bad? Think about it carefully, the gearbox or the brake pads, which is more expensive, needless to say, everyone understands in their hearts.

Therefore, to sum up, when the automatic transmission car is parked, the handbrake should be pulled first and then the P gear should be hung.

P gear, that is, parking gear, when the vehicle is in P gear, the parking locking mechanism will lock the transmission output shaft to stop the bucket, which means that when P gear, the gears in the gearbox can not be rotated.

Automatic transmission vehicle oak is equipped with the P gear function, pretending to be the parking gear of the vehicle, some owners will hang the gear to the hall cover P gear, directly turn off and lock the car, there is no habit of pulling the handbrake, so hang into the P gear without pulling the hand brake will move?

After the automatic transmission vehicle is stopped, when the P gear is hung without pulling the handbrake, the car will have a slight sign of rolling, and then the pawl and ratchet inside the vehicle gearbox will automatically bite and lock the gearbox of the vehicle.

When the automatic transmission vehicle is parked, it is recommended that the P gear of the vehicle be used with the handbrake function, so that the vehicle's handbrake is stressed first, and the vehicle is better braked. The handbrake function of the vehicle is through the steel wire cable, the brake caliper of the two rear wheels of the vehicle is locked with the brake pads, so that the vehicle brakes, the owner should pay attention to the use of the vehicle, can not use the vehicle with the handbrake function, which will increase the friction between the brake caliper and the brake disc, and easily damage the handbrake function of the vehicle.

It is not allowed to pull the handbrake after the P gear is in gear, which will make the P gear locking mechanism overly stressed and reduce the service life of the P gear locking mechanism. So it is recommended that you also tighten the handbrake after engaging the P gear. And make sure that the car has completely stopped before engaging the P gear, otherwise the locking mechanism of the P gear will be damaged.

The P gear is a parking gear and is used for parking and stalling, so all automatic transmission cars have a P gear.

When the P gear is engaged, the locking mechanism will lock the gear, which is equivalent to indirectly locking the wheel.

After engaging in P gear, the brakes cannot be moved without holding hands.

Automatic cars also have N-gear, which can also be used when parking.

When the gearbox is engaged in nth gear, the connection between the gearbox and the wheels is disconnected. At this point, the power of the engine cannot be transmitted to the wheels.

N gear is suitable for short stops without turning off the engine. When waiting for a red light, you can use the n gear.

It is not recommended to use the P stop when waiting for a red light.

If you are in P gear while waiting for a red light and are rear-ended by a car behind you, your car's automatic transmission will be severely damaged.

If the automatic transmission is damaged, the cost of repairing it is high.

Therefore, when using automatic transmission vehicles, we must pay attention to maintaining correct usage habits, otherwise the automatic transmission cavity will be damaged.
