1. Daily maintenance

1. Do not start with high grade and lift clutch pedal. Excessive impact can damage transmission mechanism, including transmission shaft.

2. The fuel tanker will have its nuclear load, excessive overload, which will aggravate the damage of the machine.

3. Check the mounting condition of the shaft hanger, whether the supporting rubber is damaged, whether the connecting parts of the transmission shaft are loose and loose, and whether the transmission shaft is deformed.

4. In order to ensure the dynamic balance of the transmission shaft, it is necessary to pay regular attention to whether the balancing welding piece is unsoldered. The new transmission shaft assembly is provided, and the assembly mark of the telescopic sleeve should be paid attention to in the new transmission axle loading, and the flange fork should be in a plane.

5. The grease should always be added to the universal shaft bearing, and 3 lithium base grease should be injected in summer and lithium 2 base grease will be injected in winter.

Ii. Major failures

1. The sliding spline and the universal shaft bearing are different

Phenomenon: when the tank car starts, the car will emit a "luo, luo" sound, especially when the vehicle is slow or speed up, the sound is more harsh.

Cause of failure: the sliding spline is badly worn; Universal bearing roller bearing needle breakage or abrasion; Drive shaft flange connect fixed bolt loose, etc.

2. Bending of the transmission shaft

Phenomenon: when the tanker is moving, a periodic sound will be emitted, and as the speed increases, the sound will become larger and larger, and the body will still shiver with severity.

Cause of failure: deformation of transmission shaft; The flange of the transmission shaft and the shaft tube welding skew; Imbalance of transmission shaft; The fixed bolt of the transmission shaft hanger is loose or the hole position is deflected.

3. The middle suspension bearing is different

Phenomenon: the tank car makes a sound and sound during the driving, and the sound increases with the increase of the speed.

Cause of failure: the middle bearing of the transmission shaft is worn, the middle rubber support is damaged or the hanger is loose and so on.

3. Removal of transmission shaft

The car front and rear wheels Xie live, use open end wrench or glasses wrench to unload the shaft end and rear axle active bevel gear flange of four fixed bolt and nut. Use a wrench to remove the four bolts and nuts of the transmission shaft front end with the transmission shaft flange and the brake drum of the parking brake. Push the drive shaft backward.

Main note:

1. Sometimes it is too tight. It can be used to remove the driving shaft by tapping the sliding fork of the axle with the hand hammer gently.

2, remove the note before mark it, if no mark, should be in the appropriate location marking, and assembly, with circlip pliers first taking out each ear canal elastic ring, left hand lift shaft end; Right hand hammer tapping ears, put a needle roller bearing, then the shaft turn 180 degrees, use the same method to another needle bearing on the flange fork out, then take the flange fork down, removed the spider, but note that you will choke crashed.

3. Check whether the surface of the shaft of the cross shaft is seriously peeled off. If it is seriously flayed, it should be replaced. If there is a slight peeling, use the fine oil stone and continue to use it.

4. Check the surface of the axial surface of the shaft with needle indentation, and if there is deep indentation, it should be replaced; If the radial clearance of the cross shaft is greater than 0.35 mm, the axial clearance is greater than 0.15mm and should be replaced. The cracked or the bearing seat (outer ring) should be replaced after inspection. Check whether the clearance between the shaft bearing and the original of the cross shaft is too large. If it is worn too much, it should be replaced.
