Problems solved by technology

[0003] For the above-mentioned traditional structure differential, the large differential shell and the lower shell are connected by several bolts, that is, how many bolt holes need to be processed, and the upper shell and the lower shell are heavy, the processing technology is cumbersome, and the installation structure is complicated. High processing cost in the process

Embodiment Construction

[0015] Such as figure 1 and figure 2 As shown, an improved differential device includes a large differential case 1, a small differential case 3 set on one end of the large differential case 1, and a small differential case 3 that is screwed to the large case 1 of the differential through screw fastening. The anti-loosening nut 2 of the small differential case 4 and the angle-tooth driven wheel 4 installed between the large case 1 and the small case 3 of the differential; Angle-tooth driven wheel block 41 is used for torque transmission.

[0016] The outer cylindrical surface of the large differential case 1 is set on a conical inclined surface, and its taper is 1-7 degrees. The large differential case 1 is provided with a basin angle tooth driven wheel installation platform on one side of the outer cylindrical surface. 11. The installation platform 11 of the basin angle tooth driven wheel is adapted to the basin angle tooth driven wheel block 41; The connection mode of t...

Abstract

The invention discloses an improved differential mechanism device, comprising a large differential mechanism shell, a small differential mechanism shell, a retainer nut and a basin angle gear driven wheel, wherein the small differential mechanism shell is sleeved at one end of the large differential mechanism shell; the retainer nut is fastened and screwed with the large differential mechanism shell and the small differential mechanism shell through a thread; the basin angle gear driven wheel is arranged between the large differential mechanism shell and the small differential mechanism shell; an outer cylindrical surface of the large differential mechanism shell is a taper and tipsily arranged; the conical degree is 1-7 degrees; a basin angle gear driven wheel mounting platform is arranged at one side of the outer cylindrical surface; and an outer thread is also arranged on the outer cylindrical surface of the large differential mechanism shell. For the differential mechanism shells, assembling, dismantling and coincided transmission of the basin angle gear driven wheel are facilitated by arranging the conical degree of 1-7 degrees and the basin angle gear driven wheel mounting platform; the retainer nut is adopted to tightly connect the large shell and the small shell in the structure; the problem that a plurality of screw holes need to be processed in the differential mechanism shells is effectively avoided; and the improved differential mechanism device is easy to produce and process, and convenient to mount and dismantle, and the production cost is greatly saved.

Description

technical field [0001] The invention relates to the technical field of main transmission parts of an automobile drive axle, in particular to an improved differential device. Background technique [0002] The differential is an important part of the car drive axle. Its function is to transmit power to the two half shafts and allow the two half shafts to rotate at different speeds at the same time, so that the axles and wheels on both sides can travel at unequal distances in the form of pure rolling as much as possible. , so as to reduce the friction between the tire and the ground; usually the differential is composed of mechanical parts such as the differential large shell, the lower shell, the line gear, the planetary gear shaft and the side gear, and the power of the engine enters the differential of the drive axle through the transmission shaft The gearbox drives the planetary gear carrier, drives the left and right half shafts, and makes the left and right driving wheels...
