Abstract

The utility model discloses an automobile differential which comprises a shell body, a first gasket, a first bevel gear, a second gasket, a second bevel gear, a cross shaft, four bevel gears and four locking gaskets, wherein the four bevel gears and the four locking gaskets are respectively arranged on shaft heads of the cross shaft, and two sides of inner holes of the locking gaskets are of a protruding non-full-circular structure. According to the automobile differential, a locking structure is increased on an original abrasion-reducing gasket, non-full-circular inner holes are adopted in the locking gaskets, the locking gaskets are matched with the cross shaft in a locking mode, the cross shaft is static relative to the shell body, abrasion to a gear is just produced, and the amount of scrap iron produced in the abrasion process is effectively reduced.

Description

Automobile differential

Technical field

The utility model relates to automobile technical field, is specially a kind of automobile differential.

Background technique

Along with the development of automobile industry, people are also more and more higher to the needs of automotive performance.In the ransaxle of power outlet terminal, the iron filings processing mode is also progressively being upgraded.Initial mode is by the strong magnets that bonds on the axle housing, adsorbs the iron filings that produce in the friction process, has again afterwards in the main mode that filter cleaner is installed that subtracts to come iron filings in the adsorpting lubrication oil.Prior art sufficient part not is that most debris removal mode is iron filings are produced adsorption treatment afterwards, and can not reduce wear, and improves the working life of car deceleration device.

The model utility content

The purpose of this utility model provides a kind of automobile differential, and the pad increase keying structure at existing automobile differential has reduced the wearing and tearing of anti-attrition pad and automobile differential housing.

To achieve these goals, the utility model is by the following technical solutions:

A kind of automobile differential comprises housing, first pad, first bevel gear, second pad, second bevel gear, cross axle and be separately positioned on four bevel gears and four locking pads on the cross axle spindle nose, wherein, described locking pad endoporus both sides are the non-completely circular structure of projection.

As preferably, a plane is respectively established in the spindle nose cylindrical both sides of described cross axle.

The beneficial effects of the utility model are:

When existing anti-attrition pad is expert at the rotation of star gear, not only with planetary pinion relative movement is arranged, and with housing relative movement is arranged.Because of gear and the heat treatment of anti-attrition pad process, wear resistance is good, and housing is foundry goods, and does not do heat treatment, and wear resistance is relatively poor, so at work, the iron filings amount that anti-attrition pad and housing wearing and tearing produce is bigger.The utility model increases keying structure at former anti-attrition pad, and the locking pad adopts non-full circle endoporus, adopts locking to cooperate with cross axle, and is then relative with housing static at work, only produce wearing and tearing with gear, effectively reduced the iron filings amount that produces in the wear process.

Embodiment

Also by reference to the accompanying drawings the utility model is described in further detail below by embodiment:

As shown in Figure 1, the utility model comprises housing, first pad 102, first bevel gear 103, cross axle 106, second pad, 110, the second bevel gears 109, bevel gear 105, bevel gear 107, bevel gear 112, bevel gear 114 and the locking pad 104,108 that is mated, 113 and 115 all are arranged on the cross axle 106.Housing comprises upper shell 101 and lower shell body 111, and upper shell 101, lower shell body 111, first pad 102, first bevel gear 103, cross axle 106, second bevel gear 109, second pad 110 are coaxial.

As shown in Figure 2, mill on the cylindrical of four spindle noses of cross axle 106 flat, cylindrical processing both sides milling flat 116, with radial location during corresponding locking pad cooperates after, no axial rotation.As shown in Figure 3, locking pad endoporus is processed as the non-completely circular structure punching press of both sides projection.Among the embodiment, locking pad endoporus is made up of two sections arc surfaces 301, two planes 302, and two planes 302 are axisymmetric.Locking pad behind the increase keying structure adopts radial location.

Adopt structure of the present utility model, cross axle is assembled on the housing, does not have relative movement with housing, and locking pad and cross axle do not have relative movement, and locking pad and housing then do not have relative movement, does not namely have wearing and tearing between the two.

As Fig. 4, shown in Figure 5, the anti-attrition pad 201-204 that arranges on the cross axle 201 in the prior art, its endoporus are circular, and cross axle 201 does not mill flat fully, and the end of spindle nose still is circle shape structure, and spindle nose has one section plane 206.The anti-attrition pad is between bevel gear and the housing, and in the proper functioning, pad and bevel gear, anti-attrition pad and housing all have relative movement.

Above embodiment only is used for explanation preferred implementation of the present utility model; but the utility model is not limited to above-mentioned mode of execution; in the ken that described field those of ordinary skill possesses; any modification of doing within spirit of the present utility model and the principle, be equal to and substitute and improvement etc., it all should be encompassed within the technological scheme scope that the utility model asks for protection.

Claims

1. an automobile differential comprises housing, first pad, first bevel gear, second pad, second bevel gear, cross axle and be separately positioned on four bevel gears and four locking pads on the cross axle spindle nose, it is characterized in that: described locking pad endoporus both sides are the non-completely circular structure of projection.

2. a kind of automobile differential according to claim 1, it is characterized in that: a plane is respectively established in the spindle nose cylindrical both sides of described cross axle.
