The order of parking handbroke pier pier on the Internet has strict "requirements"，This is mainly done to avoid damaging the gearbox when hanging P gear。In the heart，P gear is not wrong to hang up。

According to "requirements", the steps for parking are:

Parking
Hanging N gear
Tighten the handbrake
Hanging p block
Stalling away

The purpose of doing this is to prevent the slope seabet myfrom the place where the parking is available，Avoid friction when picking out P block，In fact, it is not necessary。For this, let's take a look at what the lock structure of the P block is，Help understand what we want to say later。

Seabet

The lock function of P block depends on the cooperation of lock gears and lock sales，When we hang in the P gear，Locking will get stuck in the lock gear，To achieve parking。

Why does the parking dangling

For the convenience of hanging，The gap on the gear will be designed to be a bit larger than the lock -on -sales paw，When the P gear is just hung up, there are often gaps between the two，Therefore, the body will shake。If we pull the hand brake first，The locking force is borne by the handbrake，First -hung P gear will be borne by lock sales。

Why is it strenuous

As mentioned above，Two parts are tightly pasted, and they must overcome the friction when they want to separate them，This will cause us to work hard when we pick it up。

Can lock sales be responsible for this heavy task

We have two kinds of concerns，The first is to worry that the strength of the lock sales is not enough，Whether the car is parked on the slope will it damage the gearbox; the second is the friction between the two parts when the blocking is unlike，Distressed gearbox。

Actually，Auto developed for more than 100 years，This problem engineer has long thought Seabetof。Don't look at the lock -selling head，It can bear about 20000N forces。20000N What is the concept? For example, stop the car on the slope，Five 200 catties of fat people sitting above，No hand brake light relying on P block lock is completely okay。The problem of friction is not afraid，Because both parts are used in alloy steel for special thermal treatment，Can increase toughness and abrasion resistance。

Another point，If you drive a car with an electronic gear, you will find it，I can't feel any impact at all，but does not mean that these two parts of the electronic gear rod will not rub。So，This is all psychological effects，Don't worry。

Solution of obsessive -compulsive disorder

If you can't stand it，Just parking、Pulling handbrake、Hanging p block、Pine brake method is okay。Of course，If you don't care, as long as the car stops, it is stabilized，You can。(The content of the article comes from the network, please contact delete if the copyright involves copyright)
