Surprise:
Previously found that 35-40km, as long as to this point, feel the car shaking around, some people say that this phenomenon is called sieve bran, more than a year. The front tire was found to be low for the first time and improved a little after inflation. I went to test-drive the owner of the tire shop, and he said he couldn’t feel it. The tires are all overbalanced and transposed. It is easy to feel when you open it yourself, because with the addition of an armbox, the left and right shaking, the friction between the armbox and the seat skin, and the rustling sound, the passenger will be gone. The gearbox AT8 program 30 or so rises 3 gears, if vigorously 3000 revolutions accelerate, the left and right shivers more obviously. Lower the throttle or loosen the throttle, the jitter is slight and sometimes ignored. As long as you go to 40km, you won’t have it. Finally, the reason had to be attributed to the right front axle, because the inner ball cage dust cover damaged oil leakage, thought that the inner ball cage wear, left and right shaking is also in line with the various symptoms of axle damage, fixed speed. A few days ago, there were riders in the altar to change the half-axle, which made me think about the role of buffer glue again.
The glue on the right foot of the engine is changed by yourself. the steering wheel shakes before the change, and it is stable and comfortable after the change. Analysis of the left upper foot glue buffer is the up and down force, glue hard, the car body jitter has something to do with it.
The glue on the right foot of the engine buffers the force before and after. It has something to do with starting, accelerating and slowing down. Mine has also been changed. I was a little cracked before. I don’t feel anything. It may not be bad enough.
Engine left upper foot glue, gearbox bracket hanging glue, there is a vertical iron rod, with iron rod as the center, the main buffer is the left and right force, limit gearbox, engine. When the glue is aged, there will be a wide range of left and right, and the jitter will be aggravated.
So I decided to try to replace the gearbox bracket suspension glue.
After the installation was completed, it was dark, and after a few kilometers of test drive, the phenomenon of rapid acceleration and shaking left and right was gone. It was really a pleasant surprise. I didn’t hold much hope.
Rapid acceleration is even more invincible. The chassis of 307 becomes more and more popular. 3000-4000 revolutions are the peak stage of torque, and overtaking is cool. 72025km, this glue is worth it, which can be used as a reference for cyclists in similar situations.
The gearbox adjusts its own oil pressure DIY, the shift is smooth without thinking about life, 60km multi-kilometer urgent refueling 4 directly down to 2, slightly shake a throttle, 4 down 3, come directly.
Although DIY is a little tired and nervous, he grew up reading the posts of car friends, but the surprise, beauty and joy after DIY can only be felt by people who have touched their hands.

Jitter
With the installation of the armbox, it is more sensitive to the lateral jitter, because after the jitter, the armbox is rubbed against the left and right seat covers. The armbox is relatively heavy and is installed on the sub-dashboard of the central passageway. It will vibrate after shaking.
The jitter also suspected the torque converter for a time. On the Internet, there is a crown converter to solve the problem of vibration at a speed of 40-50 km. Baidu can also find many cases of body trembling caused by the torque converter, such as CRV, some of which have been solved by changing the torque converter, which may be due to the skidding of the locking clutch. It has been monitored by diagbox that when shaking, the torque converter is not locked. It was also suspected that there was something wrong with the internal pump wheel, guide wheel and turbine.
Now analysis, it may be 35-40km, torque converter increase torque is small, mainly coupling, up to 80%, torque converter work, hydraulic transmission, changes in oil pressure will also produce vibration. After 42km, the torque converter is locked and the vibration is gone.
The vibration caused by the hydraulic coupling of the torsion converter is inevitable. When the gearbox bracket suspension glue is changed, the vibration is filtered and there is no resonance. Before the first and second gear rapid acceleration is not obvious, the third gear rapid acceleration 3000 rotation jitter is obvious (may also be some drag), to reduce the throttle, now the third gear 3000 revolutions do not shake, the throttle does not need to be deliberately controlled.
It seems that the role of shock absorber should not be underestimated. Pay attention to NVH 6-7 years of rubber parts can be replaced, if you do not care about 100000 kilometers will not be too rotten.
