SDLG in Volgograd, Russia

Speaking of cities in Russia, in addition to Moscow and St. Petersburg, there is also a quite resounding name: Volgograd. Volgograd, formerly known as Tsaritsyn and Stalingrad, the famous defense of Stalingrad in the history of "World War II" took place here. Volgograd is one of the oldest cities in the Volga River Basin. It is located in the Eurasian transition zone and is a natural water and land transportation hub, which has unique and important significance. Recently, with respect for this "hero city", Shandong Lingong's "Good Russian Driver" event walked into Volgograd to pay tribute to the hero city. The drizzle in Volgograd in early spring brought nourishment to the spring ploughing of this huge Central Plains granary. In the cold spring, the enthusiasm of Volgograd drivers, who have been suppressed by the epidemic for a long time, was still unstoppable. On that day, nearly a hundred corporate customers from agriculture, warehousing, construction, municipal administration and other industries participated in the activity. After theoretical training and written examinations, competitions for flexibility in narrow working conditions, and competitions for job accuracy, the champion, runner-up and runner-up came to the fore. The champions will also travel to China with good drivers and representatives of major customers from other sites after the COVID-19 pandemic is lifted, to visit the modern smart factory of Lingong and experience the unique Chinese culture. In addition to the fierce

Reason of Gearbox failure

For a loader, there was a failure inside the gearbox. The customer overhauled the gearbox in a local repair shop. During the test run, the machine could only reverse but not move forward. The specific performance is: when the engine is started, the machine reverses when reverse gear or neutral gear is engaged, and the machine does not move when the first or second gear is engaged. The loader gearbox is a planetary power shift gearbox. The planetary gears, sun gear and inner ring gear are in constant meshing state. The power transmission is driven by variable speed pressure oil to push the pistons of each gear to compress the master and driven friction plates. To achieve. In the event of the above failure phenomenon, you should first check the change of the transmission oil pressure. Observe the variable speed pressure gauge, the pressure indicator at idling speed is about 1.3Mpa. When the gear is shifted, the pressure gauge pointer drops and quickly returns to the normal value, indicating that the pressure oil has entered the oil cylinders of each gear, and the sealing performance of the oil cylinders of each gear is good. The reason for the gearbox oil supply system can be ruled out. It can be analyzed that the reason why the loader has only reverse gear and also reverses in neutral gear may be that the reverse gear mechanism is always combined. Because when the first and second gears are engaged, despite the action of the pressure oil, the piston pushes the friction plates of the first and second gears to be normally combined. If the reverse gear mechanism cannot be separated, the forward and reverse powers will cancel each other out. Although the torque converter can output torque, the machine will not move forward or backward.
