How to use the reverse gear of the car

At present, most female drivers are called road killers on the road, especially when parking for a long time. Recently, a friend of mine just bought a new car with a manual transmission. After driving for a while, he told me that sometimes the reverse gear is not suitable, and I can often hear it&; Ldquo Lala &; That voice of rdquo, I don't know why. I looked it up on the Internet and found that many netizens also had many questions about the use of manual gear and reverse gear, and how to use reverse gear.

How to use reverse gear: reverse gear structure

If you want to know what to pay attention to when engaging reverse gear, you must first know the structure of reverse gear. Friends who want to believe that driving a manual transmission car basically know that many manual transmission cars basically have reverse locking devices, which need to be unlocked to engage the reverse gear. This is to prevent the car from mistakenly engaging the reverse gear when moving forward, which will have a great impact on the gear of the gearbox and affect the damage of parts. Most locking mechanisms of reverse gear are locked by error-proof baffles. The following video briefly introduces the working principle of the anti-misoperation baffle for friends:

How to use the car reverse gear: how to use the reverse gear?

Different types of gears have different designs in operation mode. Now there are three ways to unlock reverse gear, traditional unlocking, lifting unlocking and pressing unlocking. There are also some special unlocking methods, such as the reverse unlocking method of Buick Angola manual gearbox is similar to the button of automatic gearbox, and the manual gearbox like BMW has reverse gear on the left side of first gear. If you want to engage in reverse gear, you need to turn the gear lever to the left, and then push it to the left after stopping.

After briefly introducing the locking mechanism, let's talk about reverse gear. For family cars, most reverse gears are basically straight teeth, and the key reason is that the simple structure leads to low cost. Because the car is basically completely stationary when the reverse gear is engaged, there is no speed difference between the gears, so there is no need to use bevel gears and synchronizers. In addition, the chance of reverse gear is much less than that of forward gear, so there is no harm in using spur gear. Of course, the synchronizer and bevel gear are also designed for manual reverse gear equipped with high-end models, in order to improve the comfort when reversing.

How to use the reverse skill of the car: pay attention to reverse!

At the beginning of the article, it is mentioned that friends often have &; Ldquo Lala &; Rdquo is noisy, which is due to his irregular reaction when engaging the reverse gear, resulting in poor engagement between the shift fork and the reverse gear lock ring.

If the teeth are punched frequently, the tooth crowns of gears will be rounded and the meshing between gears will be incomplete. Moreover, this operation tends to be more and more bald, resulting in a vicious circle. Incomplete gear meshing will cause slight vibration after gear meshing, which will easily lead to gear shifting. At this time, the gearbox will be overhauled.

So how to prevent the gear from bumping? We summed up the methods to prevent gear bumps when the gear is reversed at three o'clock. Here is a brief introduction one by one:

(1) Stop and hang up.

The car hung up in reverse before it stopped, which is a big number. The bad habit of old drivers and love seems to be skilled driving. I think this will do great harm to the gearbox. This is what I mentioned above. Most family cars basically have no synchronizer in reverse gear. If you don't stop, you will definitely put on reverse gear and gnash your teeth. Therefore, when you engage in reverse gear, you should pay attention to the need to brake before engaging. This doesn't mean you drive a meat truck, but you are a professional.

② Press the clutch to the bottom.

Secondly, when you step on the clutch, you must step on it to the end. Never step on the reverse gear when the clutch is still in semi-linkage, which will also cause tooth-beating. In addition, stepping on the reverse gear needs to be gentle, not too hard, so you will occasionally hear a painful knock.

③ Backup waiting.

Finally, don't reverse the car too fast. Don't step on the accelerator to speed up reversing, which will do great harm to spur gears. Moreover, the spur gear transmission is very direct and the ride comfort is poor, so reversing quickly will make people in the car feel uncomfortable and the sound may not be very good.

After sharing the matters that should be paid attention to when using reverse gear, I want to share a little trick with my friends here: in many cars, the gear ratio of reverse gear is greater than 1 gear, so the transmitted torque is also greater than 1 gear, so if you encounter any ramps or kerbs that can't get up in daily life, you can basically try reverse gear.

Briefly introduce how to use the reverse gear of the car. I think what I have summarized is just some preventive measures that I often encounter. I hope that if the majority of netizens have experience in using manual reverse gear, they can post it in a message or in my editing blog. We can learn from each other and share our good experiences with more people.
