Transmission shaft intermediate supporting bracket and rotating shaft arrangement structure

The invention relates to a transmission shaft middle supporting bracket and a rotating shaft arrangement structure. The transmission shaft middle supporting bracket comprises a middle channel body, a transmission shaft and a supporting bracket. A rubber support is arranged in the middle of the transmission shaft, and a supporting bracket is fixed to the bottom of the middle channel body and connected with the rubber support. The bearing bracket comprises two U-shaped sheet metal parts which are arranged at an interval, bearing mounting plates are respectively fixed on two sides between the two U-shaped sheet metal parts, and two ends of the rubber support are respectively connected and fixed with the corresponding bearing mounting plates on the bearing bracket through bolts. By means of the design and arrangement of the middle supporting bracket of the rotating shaft, the manufacturing cost is saved, the weight of the whole vehicle is reduced, the NVH performance is improved, a quiet and comfortable in-vehicl
