CA1091 is the main reducer in the first or two stage?
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 double speed reducer is provided with an intermediate transition gear; the left of the driving gear is meshed with the umbrella tooth part of the middle gear; the bevel gear is coaxially provided with a small diameter straight gear; the straight gear is meshed with the driven gear. In this way, the intermediate gear rotates backward and the driven gear rotates forward. There are two stages of deceleration in the center. Because of the increase of the volume of axle, the two-stage deceleration is mainly used in the matching of vehicles with low power on the engine. Now it is mainly used in low speed and high torque construction machinery.
It's a two stage final drive!Two stage main reducer, when the main reducer is relatively large transmission, in order to ensure that the car has sufficient clearance from the ground, then the need for a two stage master reducer.First understand the single-stage reducer.
In a two stage master reducer, if the second stage deceleration is carried out near the wheel, it will actually form the independent component at the two wheels, which is called the wheel side reducer. The advantage of this is that the torque transmitted by the axle is reduced and the size and quality of the axle are reduced. The wheel side reducer can be planetary gear or a pair of cylindrical gear pairs. When a cylindrical gear pair is used to decelerate the wheel side, the upper and lower position relations between the wheel axis and the half axle can be changed by adjusting the mutual positions of the two gears. The axle, known as the gate axle, is often used in automobiles with special requirements for the position of the axle.According to the main reducer transmission than the number of stalls, can be divided into single speed and double speed type of two. At present, the domestic car basically adopts the drive ratio fixed single speed type of the main reducer. In the double speed type main reducer, there are two transmission ratios to be selected, and the main reducer actually acts as a secondary transmission.
