[0002] The automobile drive shaft support is an important part of the automobile transmission system. Its main function is to support the drive shaft and ensure its stable operation. The drive shaft is a component of the universal transmission device that can transfer power between different components. The drive shaft support plays the role of fixing and supporting the drive shaft to prevent it from excessive vibration or displacement during operation.

[0003] The Chinese utility model application number CN202223069860.X discloses an intermediate support frame of an automobile transmission shaft assembly, including a support frame body and a base, support plates are provided at both ends of the support frame body, a shock absorbing spring is provided at the bottom end of the shaft frame one, a rotating frame is fixedly connected to the inner wall of the shaft frame one, positioning holes are provided at both ends of the base, and slide grooves are provided on the outer walls of both ends of the shaft frame two. The utility model utilizes the overall structure of the support frame body and the base, and the support frame body and the base are connected up and down, so that the device is divided into upper and lower parts, which is convenient for device disassembly, and the shaft frame two is supported by a buffer pad and a shock absorbing spring two, so that the shaft frame two can move up and down while having a certain buffering force, so that when the device vibrates, a downward buffer is provided for the transmission shaft, the shock absorbing effect of the device is improved, and the device is prevented from increasing rotation wear due to vibration. However, the device still has some disadvantages during use: when the base and the support frame body are aligned, the slider corresponding to the slide groove is located on the inner wall of the support frame body, which makes the alignment operation more troublesome, so that the installation is still more troublesome.
