Abstract
The utility model relates to a differential shell and especially relates to a splined connected four-wheel drive differential shell. The splined connected four-wheel drive differential shell mainly solves technical problems that when a present differential shell is affected by a relative large radial force, an automatic centering operation cannot be performed, so that each tooth in the present differential is unevenly stressed and has relative low strength, thereby providing the differential with short service life. The splined connected four-wheel drive differential shell comprises a shell body (1) and is characterized in that a flange plate (2) is arranged on the shell body (1); the flange plate is provided with an installing hole (3); an inner cavity (4) is arranged in the shell; a driven gear cooperating surface (5) of a main decelerator on the front end of the shell is coupled with a driven gear of the main decelerator; a half shaft hole (6) passes through the shell in a horizontal direction; a planetary shaft hole (7) passes through the shell in a vertical direction; and a power output end of the shell is provided with an involute spline (8).
Description
Technical field
The utility model relates to a kind of differential casing, especially relates to a kind of spline joint formula 4 wheel driven differential casing.
Background technique
Domestic car and other class automobile have substantially all adopted symmetric type bevel gear open differential at present.The symmetric type bevel differential is comprised of planetary pinion, planet pin (cross axle or a direct selling axle) and differential casing etc.Planet pin is arranged in the corresponding planet of differential casing hole, on the axle journal of differential mechanism two ends, overlaps sliding bearing is arranged respectively, and planetary pinion is housed in housing, and planetary pinion is assemblied on planet axis.The planet axis two ends are provided with jump-ring slot, with two jump rings, are stuck on differential casing planet outer end of hole face, prevent the planet axis axial float.Planetaryly each side with a straight-tooth circular cone differential gear, be meshed.The axle journal of differential gear is bearing in corresponding hole, differential casing left and right, its internal spline is connected with semiaxis, the differential gear that the planetary pinion rotated together with differential casing is stirred both sides rotates, when wheel suffered resistance in both sides is different, planetary pinion, also through around self axis, rotating a rotation, is realized the differential of both sides wheel is driven.When but current differential casing is subject to larger radial force, can't carry out self-alignment, thereby make interior each tooth of differential mechanism stressed more inhomogeneous, intensity is poor, and the working life of differential mechanism is shorter.
The model utility content
The utility model is to provide a kind of spline joint formula 4 wheel driven differential casing, it is mainly when solving the existing differential casing of prior art and being subject to larger radial force, can't carry out self-alignment, thereby make interior each tooth of differential mechanism stressed more inhomogeneous, intensity is poor, differential mechanism working life shorter grade technical problem.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Spline joint formula 4 wheel driven differential casing of the present utility model, comprise housing, described housing is provided with flange plate, have mounting hole on flange plate, the inside of housing is provided with inner chamber, and the main reducing gear driven gear fitting surface of housing front end and main reducing gear driven gear link and connect, and housing is penetrated with half axis hole in the horizontal direction, housing is penetrated with the planet axis hole in vertical direction, and the clutch end of housing has involute splines.Housing is six grades of case four-wheel drive designs, the whole casting one-shot forming technique that adopts.Larger radial force is arranged when the stand under load due to differential mechanism, therefore for output, involute splines connects, can play self centering effect, be conducive to that each tooth is stressed evenly has intensity high, the characteristics that the differential mechanism life-span is long.
As preferably, the edge of described inner chamber is provided with the lubricant oil storage chamber.Can have lubricant oil in the lubricant oil storage chamber, thereby can be lubricated semiaxis.
As preferably, the clutch end outer surface of described housing is provided with the high frequency hardening fluid side.Fluid side is processed with quenching technology, thereby can make it wear-resistant, has improved sealability.
Therefore, the utility model arranges involute splines at the clutch end of housing, can play self centering effect, thereby makes the stressed all even of each tooth, and intensity is higher, and the working life of differential mechanism is longer, simple and reasonable for structure.
The accompanying drawing explanation
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Component, position and numbering in figure: housing 1, flange plate 2, mounting hole 3, inner chamber 4, driven gear fitting surface 5, half axis hole 6, planet axis hole 7, involute splines 8, lubricant oil storage chamber 9, high frequency hardening fluid side 10.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the spline joint formula 4 wheel driven differential casing that this is routine, as Fig. 1, comprise housing 1, housing is provided with flange plate 2, has mounting hole 3 on flange plate, and the inside of housing is provided with inner chamber 4, main reducing gear driven gear fitting surface 5 and the main reducing gear driven gear of housing front end link and connect, housing is penetrated with half axis hole 6 in the horizontal direction, and housing is penetrated with planet axis hole 7 in vertical direction, and the clutch end of housing has involute splines 8.The edge of inner chamber is provided with lubricant oil storage chamber 9.The clutch end outer surface of housing is provided with high frequency hardening fluid side 10.
During use, driven by engine gearbox input shaft rotates, make inner each grade of gear rotate, drive the main reducing gear driven gear and rotate, thereby make the differential mechanism integral-rotation, in the differential casing rotary course, planetary pinion is simultaneously in rotation, planetary pinion rotarily drives the differential gear rotation, and the differential gear internal spline drives the tire Formation of Axle Shaft Spline, thereby realizes that power is passed to tire from motor.
The foregoing is only specific embodiment of the utility model, but structure characteristic of the present utility model is not limited to this, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the scope of the claims of the present utility model.
