Abstract
The invention discloses an automobile differential machine assembly which comprises an input shaft. The input shaft is provided with a driving gear matched with the input shaft, a universal joint pin and a rear half-axle gear. The driving gear and the axial face of the input shaft are supported through a needle bearing III 1 and a needle bearing IV, the radial face is supported through a thrust bearing I and a thrust bearing II, a planetary gear is installed on the universal joint pin, and the axial direction of the rear half-axle gear is supported through a needle bearing II. The axial direction of the rear half-axle gear is supported by the needle bearings instead of a copper sleeve, so that the gap is small. Due to the fact that the planetary gear and the universal joint pin are supported by the copper sleeve in the prior art, the copper sleeve is prone to being sintered on the planetary gear; when the planetary gear and the universal joint pin are supported by the needle bearings instead of the copper sleeve, sintering is not prone to occurring. In the prior art, the planetary gear makes slide contact with an outer shell of the differential machine shell through an iron pad, and now a nylon pad is adopted, so that lubrication is better and iron scraps are not prone to being produced. According to the automobile differential machine assembly, the planetary gear copper sleeve and the rear half-axle copper pad are removed.
Description
Technical field
The present invention is specifically related to a kind of automobile differential assembly.
Background technique
In the differential assembly of automobile, traditional drive mechanism constituent elements mainly comprises: input shaft, differential lock assembly and interaxial differential assembly at present; Wherein shaft space difference speed assembly is by active cylindrical gears, planetary pinion, cross axle and rear side semiaxis etc.
Part forms.Drive the power of automobile runs via input shaft, cross axle, planetary pinion and driving and driven cylindrical gears, to be transported to respectively the main gearbox assembly of middle back axle, then through semiaxis, power is transported to left and right wheel, just can drive vehicle to run.In this transmission system, there is following problem:
1. the axial direction of rear differential gear utilizes copper sheathing to support, and Gap-Ratios is larger;
2. between planetary pinion and cross axle, by copper sheathing, support, the easy sintering of copper sheathing is on planetary pinion;
3. what between planetary pinion and differential carrier shell, adopt is that the slip of iron pad is lubricated, and poor lubricity, easily produces iron filings.
4. between rear differential gear and differential carrier shell, be that copper packing slip is lubricated, poor lubricity, easily produces copper scale.
5. the diameter of cross axle is 94mm, and cross axle easily ruptures, a little less than ability to bear.
The content of invention
The shortcoming existing for solving prior art, the present invention proposes a kind of novel automobile differential assembly.
The technical solution used in the present invention is as follows:
A kind of automobile differential assembly, comprise input shaft, the driving gear, cross axle and the rear differential gear that are mated are installed on described input shaft, described driving gear and the axial vane surface of input shaft support by needle bearing III1 and needle bearing IV, driving gear end tooth one side is provided with thrust-bearing I and thrust-bearing II, makes the suffered sliding friction of datum clamp face of driving gear end tooth one side change rolling friction into; The bevel gear part of the bottom of described driving gear and planetary pinion engagement; Described planetary pinion is arranged on cross axle, and the axial direction of described rear differential gear supports by needle bearing II, and rear differential gear and planetary pinion engagement.
Described planetary outside is provided with differential carrier shell, and described differential carrier shell coordinates with cross axle.
Between the planetary pinion of stating and cross axle, by needle bearing I, support.
The diameter of described cross axle is 97mm.
Between described planetary pinion and differential carrier shell, adopt nylon spacer I to slide lubricated.
Between described rear differential gear and shell, by nylon spacer II, slide lubricated.
Beneficial effect of the present invention is as follows:
1. the diameter of cross axle changes 97mm into by original 94mm, makes cross axle be not easy fracture, and ability to bear is strengthened.
2. the axial direction of rear differential gear is former was supported by copper sheathing before this, existing modification for needle bearing, and gap is smaller.
3. between original planetary pinion and cross axle, by copper sheathing, support, the easy sintering of copper sheathing, on planetary pinion, now changes into after needle bearing, is not easy sintering.
4. what between planetary pinion and differential carrier shell, originally adopted is that the slip of iron pad is lubricated, has now made nylon spacer into, better lubricated, is not easy to produce iron filings.
5. what between rear differential gear and differential carrier shell, originally adopted is that copper packing slip is lubricated, has now made nylon spacer into, better lubricated, is not easy to produce copper scale.
Magnet on the magnetic purge cock of this axle housing can only adsorb iron filings, can not adsorb copper scale; The planetary pinion iron pad of this structure and rear differential gear copper packing, change to after nylon material, is not easy to produce copper scale, iron filings, makes inner lubricant oil cleaner, makes the life of automobile differential assembly.
