低速行駛抖動頓挫幾乎成為雙離合變速箱的代名詞，不論是自主、合資還是進(jìn)口品牌，均難逃此厄運(yùn)。除此以外，部分品牌車型的手動、AT及CVT變速箱也出現(xiàn)同類問題，尤其是以節(jié)油、平順著稱的CVT變速箱也出現(xiàn)了大量相關(guān)投訴，令人較為意外。

The shaking and jerking during low-speed driving have almost become synonymous with dual clutch transmissions, and both domestic, joint venture, and imported brands cannot escape this fate. In addition, some brand models also have similar problems with manual, AT, and CVT transmissions, especially the CVT transmission, which is known for its fuel efficiency and smoothness, has received a large number of related complaints, which is quite surprising.

一、雙離合變速箱穩(wěn)定性成話題

1、 Stability of dual clutch transmission becomes a topic of discussion

雙離合變速箱有其自身技術(shù)優(yōu)勢，但穩(wěn)定性和可靠性存在一定短板，據(jù)車質(zhì)網(wǎng)投訴數(shù)據(jù)顯示，在抖動頓挫問題中雙離合變速箱投訴量非常大，且涉及品牌車型非常多。雖然從理論上講，雙離合器變速箱會在換擋響應(yīng)速度、油耗經(jīng)濟(jì)性等方面具備一定優(yōu)勢，但干式雙離合并不帶有單獨(dú)的冷卻系統(tǒng)，僅靠風(fēng)冷及變速箱油的熱導(dǎo)進(jìn)行散熱，在市區(qū)堵車情況下，離合器長期半聯(lián)動磨損且容易導(dǎo)致溫度升高。此時(shí)，雙離合機(jī)構(gòu)、機(jī)電控制單元及電器元部件難以承受長期的高溫考驗(yàn)，可能造成系統(tǒng)壽命的縮減、加速變速箱損壞。據(jù)悉，大眾已意識到干式雙離合產(chǎn)品中存在的問題，并生產(chǎn)出7速濕式雙離合變速箱予以替代，對此自主及美系品牌也應(yīng)加快解決產(chǎn)品穩(wěn)定性差的步伐。

The dual clutch transmission has its own technological advantages, but there are certain shortcomings in stability and reliability. According to complaint data from the Car Quality Network, the dual clutch transmission has the highest number of complaints and involves the most brand models in terms of shaking and jerking issues. Although theoretically, dual clutch transmissions have certain advantages in shifting response speed, fuel economy, and other aspects, dry dual clutch transmissions do not have a separate cooling system and rely solely on air cooling and thermal conductivity of the transmission oil for heat dissipation. In urban traffic jams, long-term semi coupled wear of the clutch can easily lead to temperature rise. At this point, the dual clutch mechanism, electromechanical control unit, and electrical components are unable to withstand long-term high temperature tests, which may result in reduced system lifespan and damage to the acceleration gearbox. It is reported that Volkswagen has realized the problems in dry dual clutch products and has produced a 7-speed wet dual clutch transmission to replace them. Both domestic and American brands should accelerate their efforts to solve the problem of poor product stability.

二、手動變速箱也不排除故障可能

2、 Manual transmission also cannot rule out the possibility of malfunction

手動變速箱在使用過程中出現(xiàn)抖動頓挫現(xiàn)象，很多車主第一反應(yīng)都是駕駛習(xí)慣問題，但在部分品牌車型出現(xiàn)投訴相對集中的情況，卻難以用個(gè)案來解釋。從故障現(xiàn)象來看，手動變速箱出現(xiàn)抖動頓挫一般是在換擋間隙，尤其是在二、三擋間切換時(shí)車輛頓挫感較為嚴(yán)重，但4S店給出的“正?，F(xiàn)象”答復(fù)，卻很難服眾。實(shí)際上，手動變速箱出現(xiàn)抖動頓挫問題，也與離合器及變速箱輸入軸、同步器等相關(guān)部件的配合有一定關(guān)系。如果出現(xiàn)曠量或安裝位置發(fā)生偏移，將會出現(xiàn)上述問題。除此以外，發(fā)動機(jī)行車電腦ECU也是出現(xiàn)頓挫感的罪魁禍?zhǔn)?，個(gè)別廠家已對此進(jìn)行改進(jìn)，更換新ECU后頓挫問題已得到解決。綜上所述，當(dāng)手動變速箱出現(xiàn)換擋抖動頓挫問題后車主不要掉以輕心，及時(shí)到4S店排查故障原因。

During the use of manual transmissions, there may be shaking and jerking phenomena. Many car owners' first reaction is due to driving habits, but in some brand models, complaints are relatively concentrated, which is difficult to explain with individual cases. From the perspective of the fault symptoms, the shaking and jerking of a manual transmission are usually during gear shifting, especially when the vehicle experiences severe jerking when switching between second and third gears. However, the "normal phenomenon" response given by the 4S store is difficult to convince the public. In fact, the shaking and jerking problems of manual transmissions are also related to the coordination of clutch, transmission input shaft, synchronizer and other related components. If there is clearance or installation position deviation, the above problems will occur. In addition, the engine's onboard computer ECU is also the main culprit for the jerking sensation, and some manufacturers have made improvements to address this issue. After replacing the ECU with a new one, the jerking problem has been resolved. In summary, when the manual transmission experiences gear shifting shaking and jerking, car owners should not take it lightly and promptly go to the 4S store to investigate the cause of the malfunction.

三、CVT變速箱也受頓挫困擾

3、 CVT gearbox also suffers from jerking

一提到CVT變速箱，不少人的印象可能就是其出眾的節(jié)油性和平順性，但從接到的投訴來看，變速箱抖動頓挫問題投訴中也不乏CVT的身影。其中，日產(chǎn)品牌所使用的CVT變速箱可謂命運(yùn)多舛，冬季升擋慢的問題還未絕跡，如今抖動頓挫問題的出現(xiàn)又波及多款車型，而且從故障現(xiàn)象看其中有共通之處。其主要表現(xiàn)為：30-50km/h升擋時(shí)有明顯拖曳感和頓挫感；在停車減速到15-18km/h時(shí)速時(shí)，會出現(xiàn)兩次較為明顯的頓挫感，隨后出現(xiàn)竄車。據(jù)了解，日產(chǎn)所使用的這款CVT變速箱帶有一套行星齒輪組，而出現(xiàn)頓挫感是否與其結(jié)構(gòu)有關(guān)，目前廠家及4S店并未給出明確說明。

When it comes to CVT transmissions, many people's impression may be of their excellent fuel efficiency and smoothness, but from the complaints received, it can be seen that CVT is also present in the complaints about transmission shaking and jerking. Among them, the CVT gearbox used by Nissan brand has had a difficult fate. The problem of slow upshifting in winter has not disappeared, and now the occurrence of shaking and jerking problems has affected multiple models, and there are commonalities in the fault symptoms. Its main manifestations are: obvious dragging and jerking when upshifting at 30-50km/h; When slowing down to a speed of 15-18km/h during parking, there will be two noticeable jolts followed by a sudden movement. It is understood that the CVT gearbox used by Nissan is equipped with a set of planetary gear sets, and whether the jerking sensation is related to its structure has not been clearly explained by the manufacturer or 4S dealership at present.
