Embodiment Construction

[0029] Such as figure 1 As shown, the differential of the automobile front-drive gearbox of the present invention includes a differential housing 10, a side gear 20, a side shaft (not shown in the figure), a shaft 30, a transmission gear 40, an input gear 50, and a bottom Describe each part and the relationship between them in detail:

[0030] Such as Figure 1 to Figure 3 As shown, the differential case 10 has a hollow cavity 11, the cavity 11 of the differential case 10 is preferably set as a spherical cavity, the cavity 11 of the sphere can make the There is a larger mating surface between the side gear 20 and the transmission gear 40 and the differential case 10 , so that the stability of the side gear 20 and the transmission gear 40 is better. Two ends of the differential case 10 are respectively provided with a first mounting hole 12 , and a peripheral surface of the differential case 10 is provided with two opposite second mounting holes 13 . The outer shape of the d...

Abstract

The invention discloses a differential mechanism of an automobile front drive gearbox. A differential mechanism shell is provided with a hollow cavity, first mounting holes are formed in the two endsof the differential mechanism shell separately, and two opposite second mounting holes are formed in the circumference of the differential mechanism shell. Half shaft gears are located in the hollow cavity of the differential mechanism shell. One end of a half shaft is fixedly connected with the half shaft gears, and after the other end of the half shaft penetrates through the first mounting holesin the differential mechanism shell, the half shaft is movably arranged on the differential mechanism shell. The two ends of a shaft are arranged in the second mounting holes in the circumference ofthe differential mechanism shell separately. Transmission gears are arranged on the shaft, and the transmission gears are engaged with the half shaft gears. An input gear sleeves the circumference ofthe differential mechanism shell, and the input gear and the differential mechanism shell are welded and fixed in the circumferential directions of the input gear and the differential mechanism shell.The differential mechanism has the beneficial effects that the structural arrangement is reasonable, and assembly is stable and reliable.

Description

technical field [0001] The invention relates to the technical field of differentials, in particular to a differential of an automobile front drive gearbox. Background technique [0002] As an important component of the front drive transmission, the differential plays a pivotal role when the car is running non-linearly. In recent years, with the development of the automobile industry and the emergence of a large number of automobile manufacturers, low cost and high performance have become one of the indicators that most consumers pay attention to. [0003] The general structure of the existing differential is: the input gear is fixed to the differential case by bolts (the number of bolts of different torque transmissions will be different), and in order to prevent the bolts from falling off or loosening, when the differential is assembled, the bolts It is also coated with fastening glue, but there will still be bolt breakage during the test, especially under high torque cond...
