Abstract

The invention provides an installation structure of a differential and a driven bevel gear. The differential comprises a differential shell, a planet shaft, a planet gear and a half shaft gear, the differential shell is internally provided with a cavity, and the planet gear and the half shaft gear are located in the cavity; and the driven bevel gear is arranged on the differential shell in a sleeving mode and is in interference fit with the differential shell, a welding groove with the angle being alpha is formed in the attaching face of the driven bevel gear and the differential shell, the driven bevel gear and the differential shell are welded and fixed at the welding groove, and an exhaust groove is formed below the welding groove. According to the installation structure of the differential and the driven bevel gear, a bolt hole structure of the driven bevel gear is omitted, the drilling procedure is omitted, the beat is improved, the tooth thickness is reduced, the weight is reduced, and cost is reduced; bolt holes and reinforcing ribs of the differential shell are omitted, the drilling procedure is omitted, the weight is reduced, and cost is reduced; and due to the fact that resistance of the reinforcing ribs and the bolts does not exist, transmission efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of transmission devices, and in particular relates to an installation structure of a differential gear and a passive bevel gear. Background technique [0002] During the driving process of the car, the main reducer and the differential transmit the main torque, the torque is transmitted from the engine, transmitted to the main reducer through the transmission shaft, and the differential is driven by the driving bevel gear and the tooth surface of the bevel gear. , half shaft and wheels rotate to realize torque transmission; the passive bevel gear drives the differential to rotate through the connection with the differential case to realize torque transmission. The connection between the gear teeth and the differential is the key to affecting torque transmission and transmission efficiency. At present, the connection between the passive bevel gear and the differential case is bolted. The passive bevel gear ...
