Working principle of basin angle teeth:

The single-stage reducer is a driving vertebral gear (commonly known as angle gear), and a slave basin angle tooth. The driving vertebral gear is connected to the transmission shaft, rotates clockwise, and the slave basin angle tooth is attached to its right side, and the meshing point rotates downward with the The wheels move in the same direction. Because the diameter of the driving bevel gear is small and the diameter of the basin angle teeth is large, the deceleration function is achieved.

The two-stage reducer has an additional intermediate transition gear. The left side of the driving cone gear meshes with the bevel gear part of the intermediate gear. The basin angle gear has a small diameter spur gear coaxially, and the spur gear meshes with the driven gear. In this way, the intermediate gear rotates backward and the driven gear rotates forward. There are two levels of deceleration process in the middle.

Because double-stage reduction increases the volume of the axle, it was mainly used in the past to match vehicles with low engine power, and was mainly used in low-speed and high-torque engineering machinery.

In a two-stage main reducer, if the second stage deceleration is performed near the wheels and actually constitutes an independent component at the two wheels, it is called a wheel reducer. The advantage of this is that it can reduce the torque transmitted by the half shaft, which is beneficial to reducing the size and mass of the half shaft. The wheel reducer can be of planetary gear type, or it can be composed of a pair of cylindrical gear pairs. When using a cylindrical gear pair for wheel speed reduction, the up and down positional relationship between the wheel axis and the axle shaft can be changed by adjusting the mutual positions of the two gears. This type of axle is called a portal axle and is often used in cars that have special requirements for the height and position of the axle.

According to the transmission ratio of the main reducer, it can be divided into two types: single-speed type and double-speed type. Domestic cars basically use a single-speed main reducer with a fixed transmission ratio. The two-speed main reducer has two optional transmission ratios. This main reducer actually functions as an auxiliary transmission.
