Abstract
The invention provides a differential mechanism shell; the upper end and the lower end of the hollow internal side wall of the left differential mechanism shell are respectively provided with a spherical surface; the left differential mechanism shell is internally provided with a hole used for installing cross shafts respectively in the transverse direction and in the longitudinal direction; the transverse cross shaft hole is vertically crossed with the longitudinal cross shaft hole; the right differential mechanism shell is an end cover; the circumference of the right differential mechanism shell is connected with the circumference of the left differential mechanism shell by a bolt; the differential mechanism shell improves the production efficiency, reduces the market malfunction rate, increases the bearing capability and reduces the manufacture cost simultaneously.
Description
Technical field
The present invention relates to a kind of automobile differential, particularly a kind of enclosure interior structure of automobile differential.
Background technique
The open differential housing is divided into differential left shell and right shell when design; the differential cage that is occurred is left shell and separately branch half design of right shell in the market; the sphere of differential casing divides the false add worker, causes its sphere centre line position uncertain, error occurs through regular meeting; four hole perpendicularities and the degree of symmetry of cross shaft hole are overproof; when assembling planetary pinion pad, the pad specification is many, should not adjust like this; manufacturing efficiency is low, the quality instability.Because of the skew of center line, planetary pinion and differential gear are in movement process simultaneously, and speed is inhomogeneous, and causing planetary pinion and differential gear to be killed with planetary pinion has cracked fault often to take place.The open differential housing divides half design, requires could form differential case assembly after pairing left and right one pairing, when breaking down in market, must change whole differential housing assembly, can not accomplish the exchange of differential carrier.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, proposed a kind of split surface and moved on to the right side, remove the new structure of screw hole at the smallest cross-sectional place of differential casing differential casing, improved manufacturing efficiency, reduce the market rate of fault, increased bearing capacity simultaneously, reduced manufacture cost.
The present invention is achieved by the following technical solutions:
A kind of differential carrier comprises by left and right differential casing and forming, and the hollow madial wall top and bottom of described left differential casing or right differential casing are respectively equipped with a sphere; The horizontal and vertical hole that is used to install cross axle that is respectively equipped with in left side differential casing or the right differential casing.
A kind of differential carrier, the hollow madial wall top and bottom of described left differential casing are respectively equipped with a sphere; The horizontal and vertical hole that is used to install cross axle that is respectively equipped with in the differential casing of a left side.
A kind of differential carrier, described horizontal cross shaft hole and longitudinal cross shaft hole intersect vertically.
A kind of differential carrier, described right differential casing is an end cap; The periphery of right differential casing is connected by bolt with the periphery of left differential casing.
The hollow madial wall top and bottom of the present invention left side differential casing are respectively equipped with a sphere, sphere is done as a whole, processing simultaneously, eliminated the problem of sphere diameter center line appearance skew and error, effectively guaranteed the quality of product, the market quality accident that elimination is caused because of the sphere diameter disalignment, can realize the exchange of differential casing, its cross shaft hole is disposable machining, guarantee the perpendicularity and the degree of symmetry requirement of product requirement, saved reprocessing and twice caused error of clamping after tightening with bolt simultaneously, so just saved machining period, also save the input of man power and material and machine tool, saved processing cost.The plane of its assembling cross axle moves up, the space of differential mechanism integral body diminishes, reserving the installation master is increased by the space of dynamic bevel gear, it is main by the external diameter of dynamic bevel gear to utilize this space to increase, increase the master by the intensity of dynamic bevel gear, the phenomenon of having avoided traditional differential mechanism when increasing the master, to bump inadequately because of the space by the intensity of dynamic bevel gear.Because of its sphere and cross axle are one piece processing, needn't use as the shell pairing back, the left and right sides of open differential shell, when quality problems or market fault appear in differential mechanism, can directly change left shell and right shell, when guaranteeing quality of product, saved the existence of the cost waste of integral replacing.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Shown in accompanying drawing.
A kind of differential carrier of the present invention, the hollow madial wall top and bottom of left differential casing 1 are respectively equipped with a sphere 5; The horizontal and vertical hole that is used to install cross axle that is respectively equipped with in the differential casing 1 of a left side.Horizontal cross shaft hole 3 intersects vertically with longitudinal cross shaft hole 4.Right differential casing 2 is an end cap; The periphery of right differential casing 2 is connected by bolt 6 with the periphery of left differential casing 1.
Such differential casing is adding man-hour, sphere 5 is done as a whole processing simultaneously, and be arranged in the left differential carrier 1, eliminated the problem of sphere diameter center line appearance skew and error, effectively guaranteed the quality of product, the market quality accident that elimination is caused because of the sphere diameter disalignment, can realize the exchange of differential casing, its cross shaft hole is disposable machining, guarantee the perpendicularity and the degree of symmetry requirement of product requirement, saved reprocessing and twice caused error of clamping after tightening with bolt simultaneously, so just saved machining period, also save the input of man power and material and machine tool, saved processing cost.
