In our life, the transmission shaft center hanger is generally used for trucks, but not for small cars. The reason is that the distance between the transmission main shaft of small cars and the driving gear shaft of the rear axle reducer is short, and a set of transmission shaft assembly is used to connect. Therefore, the transmission shaft center hanger is not set, while the distance between the drive shaft and the driven shaft of trucks is far, and the transmission shaft has a connection part, so the center hanger is used.

Where is the transmission shaft center hanger generally installed? Generally speaking, the center hanger is located in or under the beam in the frame. Some hangers are installed in the beam with bolts, and some are hoisted under the beam. The hanger has two sets of ball bearings and a bearing seat, and rubber ring pads of different shapes are used to attach between the periphery of the bearing seat and the hanger seat hole. The rear end of the front drive shaft is positioned by the center hanger, which can ensure the positioning and rotation of the front and rear drive shafts. At the same time, the front drive shaft can have micro swing and axial micro play.

When the center hanger of the transmission shaft is broken, the front and rear transmission shafts will be disconnected at the expansion fork, which will cause the vehicle in motion to fail. At this time, there is a great potential safety hazard. Therefore, the center hanger of the transmission shaft should also be regularly overhauled to prevent accidents.
