Technical Field

[0001] The utility model belongs to the technical field of automotive transmission, and particularly relates to a modular automotive model transmission system. Background Technique

[0002] The automotive transmission system refers to a system that transmits the power generated by the engine to the wheels through a series of transmission devices, thereby driving the vehicle to move. This system is a crucial part of the vehicle, and its performance directly affects the vehicle's handling, comfort, and fuel economy.

[0003] However, there are some deficiencies in the existing automotive transmission systems during use. A series of parts such as bearings and gears inside the transmission system are prone to direct contact with the outside world, thus easily adhering to contaminants and being invaded by dust and water, and even affecting the automotive transmission system subsequently.

[0004] Therefore, those skilled in the art have proposed a modular automotive model transmission system to solve the above-mentioned problems. Summary of the Utility Model

[0027] As can be seen from the above, the drive mechanism of this invention uses the inner ball joint 3 of the power take-off box 2 as the moving axis of the vehicle suspension system, and extends two rigid shaft tubes, namely the front drive shaft sleeve 6 and the rear drive shaft sleeve 5, from the inner ball joint 3 to wrap the internal front and rear shafts, sealing all the automotive drive shafts in the pipeline to ensure no dust, water and other infringements, and can ensure that the front and rear shafts swing up and down with the shock absorber.

[0028] Specifically, a front axle 12 is arranged at one end of the front drive shaft sleeve 6, and front wheel axles 13 are installed at both ends of the front axle 12.
