Abstract
The utility model relates to an automobile part, in particular to a half axle gear of an automobile differential. The half axle gear of the automobile differential mainly solves the technical problems that in the prior art, gear tooth ends of the half axle gear and the end face of a half axle gear body are not on the same plane, so that the half axle gear hinders running of a planet gear when the planet gear is in transmission, the transmission efficiency is low, consumed materials are many, the production cost is high, and the like. The half axle gear of the automobile differential comprises a half axle gear body (1) and is characterized in that an inner rack (2) is arranged in the half axle gear body (1), the outer surface of one end of the half axle gear body is provided with gear teeth (3) arranged in a slant mode, and the gear teeth and the outer end face of the half axle gear body are located on the same plane.
Description
Technical field
The utility model relates to a kind of automobile and uses component, especially relates to a kind of automobile differential differential gear.
Background technique
In mechanical field, a lot of engineering goods, engineering machinery, Transport Machinery and mining machinery essentially will be used differential gear and planetary pinion.Chinese patent discloses a kind of locking differential differential gear (publication number: CN101936376A :) of friction disk unloading, and it comprises: housing; The cam differential gear, this cam differential gear is arranged to the first end near housing, and wherein, the cam differential gear has a cam differential gear wheel hub; First clutch assembly, this first clutch assembly are arranged to around said differential gear wheel hub; With annular connected member, this annular connected member is arranged between differential gear and the housing; The annular connected member is arranged between differential gear wheel hub and the housing, and annular connected member directly contacts with the differential gear wheel hub and directly contacts with housing, and differential mechanism is mechanical locking differential; Differential mechanism also comprises: engaging mechanism, engaging mechanism be configured to have at least one can move to extended position from retracted position the engaging mechanism part; And locking framework, this locking framework is configured to engage with the part of engaging mechanism; Differential mechanism also comprises the second clutch assembly, and this second clutch assembly is arranged to the first end near housing, also comprises the clutch cam dish that is arranged between said cam differential gear and the second clutch assembly; The clutch cam dish comprises one group of external tooth on radially-outer surface, and the clutch cam dish comprises the cam face with a plurality of cam ramp; The cam differential gear comprises that one has the cam face of a plurality of cam ramp and a plurality of braking part, and a plurality of braking part are corresponding with a plurality of cam ramp on the said clutch cam dish.But the end face of the wheel tooth ends of this differential gear and differential gear body is not at grade, so it can hinder planetary running when the transmission planetary pinion, and transmission efficiency is lower, and used material is more, and cost of production is bigger.
The model utility content
The utility model provides a kind of automobile differential differential gear; Its mainly be solve the existing in prior technology differential gear wheel tooth ends and differential gear body end face not at grade; Therefore it can hinder planetary running when the transmission planetary pinion; Transmission efficiency is lower, and used material is more, the technical problem of the bigger grade of cost of production.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals:
The automobile differential differential gear of the utility model; Comprise the differential gear body; The inside of described differential gear body is provided with interior tooth bar, and the outer surface of differential gear body one end is provided with the gear teeth of oblique setting, and the exterior edge face of the gear teeth and differential gear body is positioned on the same plane.The interior tooth bar of differential gear body interior can be connected with semiaxis, and the gear teeth of differential gear body exterior can mesh with the planetary gear teeth, thereby can accomplish transmission.The differential gear body and the gear teeth are that cast inblock forms, its carburized layer depth 0.8-1.2, surface hardness HRC58-64, centre hardness HRC33-48.The face cone angle of the gear teeth is 60o9 ' 7 ", reference cone angle is 54o27 ' 44 ", Root angle is 46o23 ' 49 ".
As preferably, the joint of the described differential gear body and the gear teeth is provided with groove, groove by cambered surface, with and the plane that connects, two ends form, the groove two ends are provided with the groove chamfering.Groove can be used for keeping somewhere fluid, can play lubricated effect.
As preferably, the two ends that described differential gear body is inside and outside all are provided with chamfering.Chamfering can be convenient to differential gear and other auto parts and components are assembled, and prevents that differential gear from scratching other component.
Therefore, the utility model is arranged on the end face of the differential gear body and the gear teeth in the same plane, can prevent that differential gear hinders planetary pinion to be rotated when transmission, and transmission efficiency is higher, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the utility model;
Accompanying drawing 2 is A-A cross-sectional view of Fig. 1;
Accompanying drawing 3 is I portion structure for amplifying schematic representation of Fig. 1.
Component, position and numbering among the figure: differential gear body 1, interior tooth bar 2, the gear teeth 3, groove 4, groove chamfering 5, chamfering 6.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: the automobile differential differential gear that this is routine; Like Fig. 1, Fig. 2; A differential gear body 1 is arranged; The inside of differential gear body is provided with interior tooth bar 2, and the outer surface of differential gear body one end is provided with the gear teeth 3 of oblique setting, and the exterior edge face of the gear teeth and differential gear body is positioned on the same plane.The two ends that the differential gear body is inside and outside all are provided with chamfering 6.Like Fig. 3, the joint of the differential gear body and the gear teeth is provided with groove 4, groove by cambered surface, with and the plane that connects, two ends form, the groove two ends are provided with groove chamfering 5.
During use, differential gear body 1 and semiaxis are linked together, mesh together and to use through the gear teeth 3 and planetary pinion again through interior tooth bar 2.
The above is merely the specific embodiment of the utility model; But the structure characteristic of the utility model is not limited thereto; Any those skilled in the art is in the field of the utility model, and variation of being done or modification all are encompassed among the claim of the utility model.
