Improved combined differential mechanism

Abstract

The invention discloses an improved combined differential mechanism, and relates to the technical field of differential mechanisms, the improved combined differential mechanism comprises an outer shell and a lubricating assembly, a cavity is formed in the outer shell, a bevel gear is mounted in the cavity, the surface of the bevel gear is meshed with a driving gear, and the outer end of the top of the driving gear is connected with an input shaft; an output shaft is connected to the outer end of the bevel gear, and a self-locking assembly is arranged on the surface of the output shaft and comprises a gear sleeve, meshing teeth, a separation tooth cylinder, a groove, a connecting rod, an electric telescopic rod and a protection box. According to the differential mechanism, the multiple assemblies are arranged in a matched mode, the output shaft can be driven to be self-locked, the differential mechanism can rapidly stop and rapidly conduct steering action, the differential mechanism can be reset after stopping is completed, use of the differential mechanism is convenient, multiple positions in the differential mechanism are connected during splicing, follow-up maintenance and overhaul are facilitated, and the service life of the differential mechanism is prolonged. And meanwhile, a replacement assembly is further arranged outside the output shaft, so that the later replacement process is facilitated.

Description

technical field [0001] The invention relates to the technical field of differentials, in particular to an improved combined differential. Background technique [0002] The automobile differential can make the left and right (or front and rear) drive wheels rotate at different speeds. It is mainly composed of left and right side shaft gears, two planetary gears and a gear rack. When driving on the road, make the left and right wheels roll at different speeds, that is, 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, at this time, it is necessary to add an intermediate diff...

Problems solved by technology

[0003] Differentials on the market have the disadvantages that they cannot be self-locked, which limits their use, and the structure is often too complicated, which is not conducive to disassembly and maintenance.
