Problems solved by technology
This structure has many disadvantages: (1) It needs electric control or hydraulic control, and the structure is complicated; (2) Because it relies on friction to generate resistance, it requires high wear resistance of the side shaft gear and metal friction plate, which increases the production cost. ; (3) After the metal friction plate is worn out, it is very inconvenient to replace. Usually the differential is replaced as a whole, resulting in higher maintenance costs

Embodiment Construction
[0021] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
[0022] Such as figure 1 and figure 2 As shown, the limited-slip differential includes a differential case 1, and the differential case 1 is provided with a power input device, and the power input device includes a The power input gear 12 is fixed on the differential case 1 through several connecting bolts 13 evenly arranged in the circumferential direction.
[0023] Both ends of the differential case 1 are respective...

The invention discloses a limited slip differential. The limited slip differential comprises a differential shell, axle shafts are arranged on the differential shell, axle shaft gears are arranged atthe ends of the two axle shafts, a differential transmission device is arranged in the differential shell, an inner limited slip sleeve is arranged on each axle shaft, an outer limited slip sleeve isarranged on the differential shell, an annular limited slip space is formed between the inner limited slip sleeve and the outer limited slip sleeve, a limited slip end cover is arranged on a port of the annular limited slip space in a sealed manner, the limited slip end cover is in sliding connection with the inner limited slip sleeve or outer limited slip sleeve, and the interior of the annular limited slip space is filled with high viscosity liquid. A limited slip inner ring piece is arranged on the inner limited slip sleeve, and a limited slip outer ring piece is arranged on the outer limited slip sleeve. When wheels on one side of a car slip, the high viscosity liquid can play a viscous retardation role in t he axle shafts, the metal friction retardation effect is replaced, and runningsafety is ensured; the limited slip end cover, the inner limited slip sleeve and the outer limited slip sleeve are wholly detached down and then are maintained, the structure is simple, and electriccontrol or hydraulic control is not needed.
Description
technical field [0001] The invention relates to a differential, in particular to a limited-slip differential. Background technique [0002] The differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. When the car turns or one side of the wheel slips, the speed of the wheels on both sides can be self-adjusted. [0003] Now used for anti-skid differential, its structure is roughly as follows: two semi-shafts are arranged symmetrically on the casing, bevel gears are respectively arranged at the inner ends of the two half-shafts, a planetary gear carrier is installed on the casing, and two shafts are arranged on the planetary gear carrier. One or four planetary gears meshing with two bevel gears at the same time. When the car is running normally, the rotation speed of the casing is equal to that of the half shaft, and the planetary gear does not rotate. The gears start to turn, achieving different speeds.
