Automatic car parking, the reason why there are owners who support the first turn off and then hang up the P gear, is worried that when pushing from N gear to P gear, it will go through reverse gear, at this time the engine is idle state, which will impact the gearbox car. And some car owners support the first hanging P gear and then extinguishing, thinking that this way parking is safer, so there is a disagreement, how to stop the automatic gear, is it the first to turn off the fire or hang the P gear first? Let's start with the principle, know the correct parking habits, don't wait for the gearbox to be scrapped to know!
Careful owners can find that there are relevant instructions on the car instruction manual, when the car brakes and stops, it is hung into the N gear, and then the handbrake is loosened and the foot brake is pulled, and finally the flameout is hung into the P gear. Strictly speaking, N gear and P gear are empty gear, but P gear is installed on the basis of the neutral gear with a set of parking devices, that is, the addition of pawls and corresponding gears, when we stop and hang into P gear, pawls and gears are combined to achieve the purpose of parking. Therefore, when we stop and hang the P gear, the pawl is combined with the gear, if we do not stop correctly, it will cause the pawl to be forced all the time, and eventually lead to the scrapping of the gearbox.
Turn off the ignition first and then hang up the P gear, in the process of pushing the N gear to the P gear, will the R gear perform the action? No, the reason is that we all have electronic delay devices in our cars that make them not perform reversing motions. In addition, it will also cause trouble that the car cannot be plugged into the P gear after the key cannot be pulled out, and we need to hang into the P gear again. For a car that starts with one key, if you do not put on the P gear and stop, at this time only the engine stops working, and the vehicle's power supply system does not stop, which is equivalent to the effect of us screwing the key to the ACC gear, and locking the car through the key is not OK.
Hang up the P gear first and then turn off, which is the choice of most of our car owners, it is recommended that everyone do this, it is not easy to appear that the car cannot be locked after the car is turned off, and the key cannot be pulled out. So how to park the automatic car? It is recommended that our car owners park like this: after stepping on the brakes, the car is parked, hang into the N gear, pull the handbrake or the electronic handbrake, loosen the foot brake, and finally hang into the P gear to stop the fire. The reason why the first hang N gear and then hang into the P gear, in order to prevent the car from stopping, relying on not the brake system but the bite of the P gear locking mechanism, that is, the car parking relies on the bite of the pawl and the gear in the gearbox, if the vehicle suffers from external force impact at this time, the wheel rotation is bound to drive the gearbox, so that the pawl is more forced. In this case, the pawl jams the gearbox, will be due to external forces caused by the ejection, friction with the parking gear, issuing a harsh toothing sound, with the accumulation of time, it will lead to the pawl to break, broken iron will fall into the gearbox, resulting in the transmission overhaul, or even scrapped.
Therefore, automatic car parking, we need to master the correct parking habits, whether it is first turned off or first hung P gear is OK, but the premise is to hang into N gear in advance, the use of brake system to park, rather than through the P gear parking device to park, do not wait for the gearbox scrap does not know. Finally, Dazhao would like to ask you a question: when you park, how do you stop, is it directly from the D gear to the P gear and then pull the handbrake? Feel free to leave your thoughts!
