What are the causes of hanger damaged drive shaft center?
(1) the reason hanger bearing damage is bearing inner lack of oil, resulting in increased bearing wear or erosion and looseness, or because of disrepair, the outer diameter of bearing and bearing seat hole to rotate loose rubber ring bearing seat, the periphery of the rupture or fall off, forming the drive shaft in the financial frame beat, by using frame lower part fracture, the fracture of bolts and bolt connection broken.
(2) the damage reason of the transmission shaft part is around the drive shaft, universal joint fork flange fork uranium, bonding, keyway expansion joint shaft deformation, generating axis swing makes a set of drive shaft or universal joint transmission; Tian lack of lubrication oil and excessive wear loose; or because of expansion joint sliding groove and the groove between the intensified wear loose etc.. The set of drive shaft in the transmission gap volume increases and generating axis shimmy, center hanger long-term subject to its shock effect and lower fracture.
(3) a drive shaft center hanger truck, in the forty years since the car maintained bearing thrust (tile frame) towel heart stent type of Qi in the beam, material to be Duan Zhutie (Ma Gang) casting, hanger this structure only adapt to cut heavy truck tonnage relatively low (Modern a drive shaft center support to steel coil pressure welding material, set in a beam, compared to insurance). Casting, metal hanger because of improper Liu pine or blowhole, material is brittle fracture layer is easy to produce. In the warranty installation center due to improper method when the hanger fastening bolts, no balance evenly mounting hanger or assembly hanger cover, make the hanger or hanger cover Alice outfit, a point of stress concentration appears to cause fracture, hanger broken.
Several factors causing damage to a drive shaft center hanger as long as there is a, will cause incalculable damage to vehicles. Therefore, regular maintenance of vehicles or warranty should be focused on checking on the transmission part and the adjustment.
