7=SimSun Jetta å˜é€Ÿå™¨ gear transmission without reverse gear failure â–¡ Zhou Xing is now a large number of Jetta cars in the society, in 1999, for example, Jetta car sales of about 80,000 vehicles, in addition to urban pioneers and urban sunshine The workers' illusion is an automatic transmission, which is usually a manual mechanical transmission. This series of cars, the speed range is a rotating magnet type structure, the transmission shaft is connected to the transmission shaft through the transmission gear. In the process of replacing the speed-speed transmission flexible shaft, it is necessary to pay attention to the removal of the transmission flexible shaft from the transmission. The action should be light, especially when the transmission gear of the shaft of the transmission drive shaft is pulled out of the transmission housing. Should first smash the hole in the transmission housing, and then try to pull it outwards, not rough operation. If the hard pull is pulled, the transmission gear of the drive shaft will be scraped off in the transmission case, and the original The fault is more complicated, or a new fault is created.
When installing the transmission speed drive shaft and the change speed of the drive shaft, the first time should check whether the circlip of the drive shaft is in the slot. When the drive gear is installed, it should be heard. The sound of the clear sound is loud. It is worth noting that the current market, the speed of the transmission of the flexible shaft assembly, the head does not have a circlip, so when replacing the speed of the shaft, the shank on the old shaft head must be kept.
The most savvy method is to remove the circlip on the 15-axis head, the horse is mounted on the new flexible shaft, and finally check whether the transmission gear is firmly coupled with the drive shaft. The circlip can be observed through a lateral inspection hole on the transmission gear. If the circlip is not visible, the position is incorrect and needs to be reassembled.
The main drive and differential of the Jetta's transmission are the combination of the parts. The design is reasonable and easy to operate. Under normal circumstances, the transmission has few faults. Maintenance usually only needs to check the shifting control mechanism of the lubrication transmission and check the replacement transmission gear oil. Jetta's gear transmission requirements for gear oil are more stringent and have excellent wear resistance, and the sealing material should have an excellent match with 3 people. 75 pairs of American engineers' associations and recommendations are best to use the special gear mooring designated by the Volkswagen Company.
On the other hand, it can be seen from this repair accident that in our maintenance industry, chaotic management will inevitably cost the enterprise a heavy price. This requires our maintenance department to strictly follow the maintenance specifications and Ding Yi. We must carry out the quality inspection process seriously; require our employees to have a strict and responsible professionalism and professional ethics. Our maintenance operations directly affect the quality of the completed vehicles and the personal safety of the owners, like the above-mentioned malignant Jetta King pressure 17 0, the car, suddenly reversed can not hang, but the forward gear is normal, come to my station for repair. The car has traveled 140,000 kilometers. The main owner said that he had heard abnormal noise in the transmission and had replaced the speed-speed shaft one month ago. After the test drive, the reverse gear could not be hanged, and the forward gear was normal. Inspection revealed oil leakage at the drive differential flange on the right side. It is preliminarily judged that there is a foreign object in the transmission, and it is suspected that the shifting operation mechanism is generated for the suction bearing and the gear wear in the transmission, so that the reverse gear cannot be hung. Decided to disintegrate.
Through the above maintenance, we believe that this case of the transmission without reverse gear failure is completely an artificial repair liability accident, the repairman is replacing the speed mileage for poverty.
The transmission gear of the speed-speed transmission flexible shaft is scraped off in the transmission. After installation, it is not carefully checked, and it loses its sense of responsibility and professional ethics, swindling the owner and causing major danger to the owner.
