Abstract
The utility model discloses a novel driving axle differential mechanism, including a differential shell body I, a differential shell body II, a big bevel gear, a small bevel gear, a big bevel gear filling piece, a small bevel gear filling piece and a cross axle. The utility model is characterized in that: the hollow part of the small bevel gear filling piece is quadrangular, two sides of the quadrilateral are straight lines and the other two sides are opposite arc lines; the sheathed cross section shape of the cross axle into the small bevel gear filling piece matches the quadrilateral in the middle of the small bevel gear filling piece. The utility model can decrease the abrasion due to rotation between the differential shell body and the small bevel gear filling piece, prolonging the service life of the differential shell body, with a simple manufacturing process; in addition, the utility model is convenient for introducing lubricating oil, sufficiently making the lubricating oil into the differential shell body to lubricate the big and small bevel gears and the big and small bevel gear filling pieces, to conduct maintenance work on the differential mechanism.
Description
Technical field
The utility model relates to the differential mechanism of loader ransaxle, particularly a kind of novel ransaxle differential mechanism that possesses the anti-rotation lubricating function.
Background technique
The effect of differential mechanism mainly is can realize that two wheels have speed difference when making situations such as vehicle travels in the turning process or on the uneven road surface.The ransaxle differential mechanism that is used for wheel loader at present all adopts open differential, the characteristic of this differential mechanism is the not poor power of differential, therefore this differential mechanism failed component mainly is big bevel pinion pad, and be because the rotation of big bevel pinion pad aggravates itself and wearing and tearing between housing, the big conelet tooth, cause the variation of bevel gear wheel mounting distance to beat tooth.The working life of existing differential mechanism is shorter, and existing structure can not fully make lubricant oil enter lubricated big bevel pinion and big bevel pinion pad in the differential casing.
Summary of the invention
The utility model is intended at above-mentioned existing in prior technology problem, a kind of novel ransaxle differential mechanism that can solve anti-rotation and lubrication problem well is provided, can reduce the wearing and tearing between housing and the pad, and the abrasion between gear, cross axle and differential casing, thereby the working life of prolongation ransaxle differential mechanism.
To achieve the above object of the invention, the technological scheme that the utility model adopted is as follows:
A kind of novel ransaxle differential mechanism, comprise differential casing I, differential casing II, bevel gear wheel, bevel pinion, bevel gear wheel pad, bevel pinion pad and cross axle, it is characterized in that: the hollow space of described bevel pinion pad is quadrilateral, described tetragonal both sides are straight line, and both sides are camber line in opposite directions in addition; Described cross axle is socketed on the sectional shape of the part in the bevel pinion pad and the quadrilateral in the middle of the bevel pinion pad is complementary.
Also be provided with the lubrication groove that lubricant oil is imported to hollow space on described bevel pinion pad and the plane that bevel pinion contacts.
Advantage of the present utility model is as follows:
The utility model can reduce the wearing and tearing that produce because of rotation between differential casing and the bevel pinion pad, prolong the working life of differential casing, and production technology is simple; The convenient lubricant oil that imports of the utility model fully makes lubricant oil enter lubricated big bevel pinion and big bevel pinion pad in the differential casing simultaneously, carries out the maintenance work to differential mechanism.

Embodiment
Embodiment 1
A kind of novel ransaxle differential mechanism, comprise differential casing I1, differential casing II2, bevel gear wheel 3, bevel pinion 4, bevel gear wheel pad 5, bevel pinion pad 6 and cross axle 7, the hollow space of described bevel pinion pad 6 is quadrilateral 8, the both sides of described quadrilateral 8 are straight line, and both sides are camber line in opposite directions in addition; Described cross axle 7 is positioned at the sectional shape of bevel pinion pad 6 parts and the shape of bevel pinion pad 6 middle quadrilaterals 8 is complementary.
Described bevel pinion pad 6 and bevel pinion 4 plane contact also are provided with the lubrication groove 9 that lubricant oil is imported to hollow space on the plane of bevel pinion pad 6.
The position that combines with bevel pinion pad 6 at cross axle 7 processes flat side, the i.e. quadrilateral on two arc limits of two straight flanges, can limit bevel pinion pad 6 relatively rotates with cross axle 7, make differential mechanism 4 wearing and tearing of having avoided bevel pinion pad 6 and housing differential casing with the pad wearing and tearing of bevel pinion when work, therefore prolong the life-span of differential casing.
Embodiment 2
A kind of novel ransaxle differential mechanism, comprise differential casing I1, differential casing II2, bevel gear wheel 3, bevel pinion 4, bevel gear wheel pad 5, bevel pinion pad 6 and cross axle 7, be provided with 4 anti-rotation lubrication grooves 10 in the described differential casing about center of circle symmetry, wherein there are 2 to be located in the differential casing I1, be located in the differential casing II2 for 2 in addition, the bevel gear wheel edge is provided with 2 anti-rotation otic placodes 11 about center of circle symmetry, and anti-rotation otic placode 11 is placed on clamping in the anti-rotation lubrication groove 10.Process hollow space at the hollow space of the bevel pinion pad 6 of this differential mechanism and be quadrilateral 8, the both sides of described quadrilateral 8 are straight line; Both sides are camber line in opposite directions in addition, and described cross axle 7 is positioned at the sectional shape of bevel pinion pad 6 parts and quadrilateral 8 shapes in the middle of the bevel pinion pad 6 are complementary.
Described bevel pinion pad 6 and bevel pinion 4 plane contact also are provided with the lubrication groove 9 that lubricant oil is imported to hollow space on the plane of bevel pinion pad 6.
Aforesaid differential mechanism, anti-rotation and lubricating function are better, and the life-span of differential casing can prolong more.
