First, the reason for the damage of the hanger bearing is that the lack of lubricating oil in the bearing leads to the increase of bearing wear or ablation, or the rubber ring around the bearing seat is in disrepair, fracture or fall off, which leads to the loosening of the outer diameter of the bearing and the seat hole rotation, which leads to the pulsation of the transmission shaft of the fuse frame, and leads to the fracture of the lower part of the frame, bolt fracture, bolt joint fracture and so on. Bearing damage is caused by insufficient lubricating oil in the bearing, which leads to increased bearing wear or ablation, or the outer diameter of the bearing and the valve seat hole due to disrepair, fracture or fall off, which causes the fusion frame drive shaft pulsation, resulting in the lower part of the frame fracture, bolt fracture, bolt joint fracture and so on.


2. The transmission shaft parts are damaged because of the deformation of the front and rear transmission shaft, the uranium fork of the universal joint, the convex fork of the universal joint and the key channel shaft of the expansion joint, which leads to the swing deviation of the complete set of transmission axis of the transmission shaft, or the excessive wear and loose wear of the field type universal joint due to insufficient lubricating oil; Or sliding keyway and expansion joint between the grooves loosening wear aggravation. Results The overall clearance of the drive shaft increased, axial shimmy appeared, the central hanger was impacted for a long time, and the lower part of the hanger was fractured.


Three, truck drive shaft center hander since the 1940s in the car in the beam to maintain the bearing punch (tile frame) type towel core bracket, material using section cast iron (Ma steel) casting. The pylon of this structure is only suitable for small weight reduction vehicles (some modern drive shaft center supports are made of steel plate seam welding and assembled on the middle beam, which is relatively safe). Fracture layer is easy to be produced in casting hanger due to improper technology, loose metal or porosity, brittleness of materials and other reasons. During the warranty installation of the central hanger, the improper bolt fastening method resulted in the unbalanced and uneven installation of the hanger or the assembly of the hanger cover, leading to the warping of the hanger or the hanger cover, resulting in the stress concentration fracture at a certain point, and the hanger was fractured.


As long as there is one of several factors leading to the transmission shaft center hanger damage, it will cause incalculable losses to the vehicle. For this reason, the transmission components should be checked and adjusted during the regular maintenance or warranty period of the vehicle.

The role of universal coupling:


The product has a very important role in life, the product is used to connect the two shafts in different mechanisms, respectively is the driving shaft and driven shaft, it is to make it rotate together, in order to transfer the torque of the mechanical parts. The product in the role of the automobile is very large, it makes use of the characteristics of its mechanism, and so that the two axes are not the same axis, its existence of the axis Angle can realize the connection of the two axis continuous rotation, it and reliable transmission of torque and movement. The main characteristics of the product is that its structure has a large angular compensation capacity, compact structure, high transmission efficiency. And in the high speed and heavy load power transmission, some couplings also have buffering, vibration reduction and improve the dynamic performance of the shafting. The product is composed of two parts, connected with the drive shaft and the driven shaft respectively. The general power machine is connected with the working machine by means of a coupling. The Angle between the two axes is different in different structure types. Therefore, the product can have a good application in automobile.
