1. ZFAK6-90 and ZFS6-90 gearbox operation and protection a. Application and protection FAK6 90 and ZFS6 90 gearboxes are conventional layout gearboxes; therefore, they are the same as normal gearboxes; One is that the car is prohibited from igniting the engine during the running. This is because the car uses a hydraulic power steering system and an air brake system; once the engine is off, the steering assist is immediately disabled; in an urgent situation, the steering is easy to turn. Heavy and formed the incident. The engine is turned off; the air compressor does not work; this simply forms the problem of brake failure. On the other hand; from the point of view of the gearbox operation; the car is at a high speed under the condition that the engine is turned off and the gearbox is in the neutral position. Sliding; because the engine is turned off; the shaft of the gearbox stops rotating, the countershaft also stops rotating and then all the gears on the two axles stop rotating; while the two axles rotate at high speed under the propulsion of the car. Because the gearbox insists on all gears. Stopping condition; spattering smoothness cannot occur; thus the needle roller bearings in the shaft holes of the two shafts are not satisfactorily smooth and burnt quickly .
The same reason; when the car engine is faulty and cannot work normally; the car needs to be moved; the interval between the extensions exceeds 100 meters; it is necessary to disassemble the drive shaft and the drive axle; On the girders of the car; the drive axle and the drive shaft are disengaged; the speed of the extension must not exceed 60 km/h. Otherwise, the burning of the two-axis needle roller bearing is simply formed.
In the protection, we should pay attention to the liquid level of the gear oil. The gear oil volume of the gearbox can not be shortened or increased. The lack of oil is easy to form early wear and even burn out; the oil is too much to simply overheat the gearbox. There is a fuel plug on the side of the box; when the car is parked in the horizontal direction, the oil level should be at the height of the wire plug. There is a drain plug at the bottom of the gearbox. The first forced protection of the new car when it travels 2000~2500 km Medium gearbox oil should be replaced with new oil. It is best to change the oil in hot car conditions. It is necessary to change the oil according to the actual working conditions and the regular gap cycle.
b, gearbox oil gearbox smooth use of gear oil. ZF gearbox uses the international standard rules of APlGL 4 grade, viscosity grade SAE85W/90 indicator gear oil.
