Transmission shaft support: the transmission shaft hanger plays a necessary role in use. Generally, the distance between the transmission main shaft and the driving gear shaft of the rear axle reducer of small cars is short, and a set of transmission shaft assembly is used for connection, and the transmission shaft center hanger is not set. The distance between the driving shaft and the driven shaft of the truck is far, and the transmission shaft has a connecting part, so the central hanger is used.

Typically, the center hanger is located in or below the crossmember 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 attached between the periphery of the bearing seat and the hanger seat hole. The rear end of the front drive shaft is positioned by the central 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 movement.
