What is the main reducer of a car?
Single stage reducer is a driving gear (commonly known as vertebral angle tooth), and a driven bevel gear (commonly known as basin angle gear), active vertebral gear is connected with a transmission shaft, a clockwise rotation, driven bevel gear is attached on the right side, the meshing point downward rotation direction is consistent with the wheel. Because the diameter of the driving bevel gear is small, the diameter of the driven bevel gear is large, and the deceleration function is achieved.
The main reducer represents the structure of most of the single rear axle main reducer, but many of the heavy trucks now adopt the through bridge, and the main reducer of the through bridge is very different from the above structure.
The structure of the main reducer in different series is different. The old car structure, textbooks, are generally based on Dongfeng 140 of the main reducer as the model, and in fact, Dongfeng 140 of the main reducer structure is more classic, can represent the majority of the car's main reducer structure. The Dongfeng 140 main reducer as an example, the main structure is: the driving bevel gear and driven bevel gear, bearing, reducer shell assembly and the differential assembly, wherein the differential assembly is composed of a differential mechanism shell assembly, cross shaft, planetary gear and axle shaft gear, planetary gear and axle shaft gasket gear gasket.
