Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, in particular to an automobile intermediate shaft with high adaptability. Background Art

[0002] The intermediate shaft is a shaft in the car gearbox. The shaft itself is integrated with the gear. Its function is to connect the first shaft and the second shaft. By changing the shift lever, different gears are selected to mesh with each other, so that the two shafts can output different speeds, directions and torques. Usually, the gear meshing test needs to be carried out on the intermediate shaft after production.

[0003] When producing intermediate shafts, the gear parameters in the intermediate shafts will be different. The intermediate shafts generally used for experiments are integrally formed. When doing gear meshing experiments on different intermediate shafts, new shafts and gears need to be re-produced. Generally speaking, intermediate shafts with different parameters have the same shaft size and only differ in gear parameters and positions. At the same time, after the experiment is completed, the intermediate shaft used for the experiment is only used for the experiment and will not be put into subsequent installation and use, which greatly increases the overall experimental cost.
