Working Principle
Single reduction gear is a driving bevel gear (commonly known as angular gear) and a basin angle gear pair. The driving bevel gear is connected with the transmission shaft, rotates clockwise, sticks to its right side from the bevel gear, and rotates downward at the meshing point, which is consistent with the forward direction of the wheel. Due to the small diameter of the driving bevel gear and the large diameter of the bevel gear, the function of deceleration is achieved.
The double reduction has an additional intermediate transition gear.The left side of the driving bevel gear is meshed with the bevel gear of the intermediate gear. The bevel gear is coaxial with a spur gear with small diameter, and the spur gear is meshed with the driven gear. In this way, the intermediate gear rotates backward and the driven gear rotates forward. There is a two-stage deceleration process in the middle.
Due to the increase of axle volume, double reduction was mainly used in vehicles with low engine power in the past, mainly in construction machinery with low speed and high torque.
In the double reduction final drive, if the second-stage deceleration is carried out near the wheel, it actually constitutes an independent part at the two wheels, it is called wheel reducer. The advantage of this is that the torque transmitted by the half shaft can be reduced, which is conducive to reducing the size and quality of the half shaft. The wheel reducer can be planetary gear type or composed of a pair of cylindrical gear pairs. When the cylindrical gear pair is used for wheel side deceleration, the up-down position relationship between the wheel axis and the half shaft can be changed by adjusting the mutual position of the two gears. This kind of axle is called portal axle, which is often used for vehicles with special requirements for the high and low position of the axle.
According to the number of the main reducer transmission ratio, it can be divided into single-speed and double-speed.
Domestic cars basically adopt single speed main reducer with fixed transmission ratio. On the double reduction final drive, there are two transmission ratios for selection, and this main reducer actually acts as an auxiliary transmission.
