Description

Main reducer assembly of middle axle

Technical Field

The utility model belongs to the technical field of automobile main reducer assemblies, and particularly relates to a middle axle main reducer assembly.

Background

A mechanism capable of changing torque and rotation speed in a transaxle by a final reduction drive. The basic function is to increase the torque from the transmission or universal drive, while reducing the rotational speed and changing the direction of torque transmission. The main reducer is composed of one or several pairs of reduction gear pairs. The power is input from the driving gear and output from the driven gear. The final drive is a main component that functions to reduce the rotational speed and increase the torque in the drive train, and also functions to change the rotational direction of the torque when the engine is vertically disposed. The speed reduction is realized by a gear with less teeth and a gear with more teeth, and the torque rotating direction can be changed by adopting conical gear transmission. Arranging the final drive at a location before power is split to the drive wheels facilitates reducing the torque transmitted by the preceding drive components (e.g., clutches, transmissions, drive shafts, etc.), thereby reducing the size and mass of those components. The presence of the final drive serves two purposes, firstly to change the direction of power transmission and secondly to provide a common gear ratio for each gear as an extension of the variator. The output of the transmission is a torque that rotates about a longitudinal axis, while the wheels must rotate about a transverse axis of the vehicle, which requires a device to change the direction of power transmission. The main reducer is so called because the ratio of the device is a factor of the overall ratio, regardless of the gear position of the transmission. With the transmission ratio, the requirement on the speed reducing capacity of the transmission can be effectively reduced, and the design has the advantages that the size of the transmission can be effectively reduced, so that the overall arrangement of the vehicle is more reasonable. The main function of the automobile main reducer is speed reduction and torque increase.

The intermediate axle is a through axle, and the main speed reducer of the through axle mainly comprises a differential mechanism and a differential lock between intermediate and rear axle shafts, an intermediate speed reducer, a differential mechanism and the like. When the vehicle runs, the middle axle and the rear axle are both driving wheels, and larger driving force can be provided. The main reducer assembly of the middle axle is one of main parts in an automobile transmission system, and can play a role in reducing speed and increasing torque. At present, after a main speed reducer assembly of an intermediate axle of an automobile in China is installed on the intermediate axle, the meshing position of a driving gear and an idler gear is far higher than the oil level of lubricating oil, an original lubricating structure can supply oil under the driving of a gear in the main speed reducer assembly, when the automobile is started under the condition of low speed, the lubricating structure can not supply oil because the automobile does not run fast, so that the driving gear is not fully lubricated and cooled by the lubricating oil when the automobile starts, the gear is dry-ground and the tooth surface is high in temperature, and the gear is damaged.
