Abstract

The invention provides a limited-slip differential and belongs to the technical field of vehicles. The limited-slip differential comprises a left short shaft, a right short shaft, a left transmissionbevel gear, a right transmission bevel gear, a first planetary bevel gear, a second planetary bevel gear, a first planetary shaft, a second planetary shaft, a differential shell and a driving gear ring, wherein a locking disc I is fixedly arranged at the inner end of the first planetary shaft; a locking disc II is fixedly arranged at the inner end of a sliding rod; a plurality of armature blocks are buried in the locking disc II; electric conducting coils are wound around all the armature blocks; a magnetic ring is buried in the locking disc I; the electric conducting coils are capable of cutting the magnetic field of the magnetic ring, and thus an electric current can be formed; a liquid storage cavity is formed in the differential shell and filled with engine oil; a through oil hole I which penetrates through the liquid storage cavity and an inner cavity of a mounting cylinder is formed in the first planetary shaft; and a through oil hole II which penetrates through the liquid storage cavity and a sliding hole is formed in the second planetary shaft. The limited-slip differential provided by the invention has the advantage that the forcible cooling and lubricating oil circulationcan be automated.

Description

technical field [0001] The invention belongs to the technical field of automobiles and relates to a limited-slip differential. Background technique [0002] A vehicle differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear carrier. The function is to make the left and right wheels roll at different speeds when the car is turning or driving on an uneven road, that is, to ensure the pure rolling motion of the driving wheels on both sides. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive, in order to drive the four wheels, all the wheels must be connected, if the four wheels are mechanically connected together, the car cannot rotate at the same speed when driving in a curve, in order for the car to drive in a curve The rotation speed is basically the same...
