Background technique
In prior art, housing and the gear ring of differential mechanism are bolted to connection.This differential mechanism quality weight, cost is high.Gear ring is thick, and has 8 high-strength bolts.
And then differential mechanism of the prior art has the little drawback of transmitting torque.Because the friction torque transmitting torque produced by bolt presses, is limited by friction factor and impacting force between housing and gear ring, causes transmitting torque little.
Model utility content
Be bolted to overcome between the housing of differential mechanism in prior art and gear ring, cause the technical problem that transmitting torque is little, the utility model provides a kind of differential mechanism and automobile.
In order to solve the problems of the technologies described above, the utility model adopts following technological scheme:
The utility model provides a kind of differential mechanism, comprises housing and gear ring, and the outer surface of described housing arranges external splines;
Described gear ring comprises a mounting hole, and the inwall of described mounting hole arranges internal spline;
Described housing inserts in described mounting hole along the axis of described gear ring, and described external splines engages with described internal spline, and described housing and described gear ring are fixed.
Furthermore, in described differential mechanism, described gear ring comprises outer ring and inner ring, and the more described inner ring in described outer ring is away from the axle center of gear ring; Described outer ring and described inner ring are arranged with one heart, and the thickness of described outer ring is greater than the thickness of described inner ring.
Furthermore, in described differential mechanism, described internal spline is arranged on described inner ring.
Furthermore, in described differential mechanism, described external splines arranges one week along the outer surface of described housing; Described internal spline arranges one week on described inner ring.
Furthermore, in described differential mechanism, described external splines and described internal spline are rectangular spline.
The utility model additionally provides a kind of automobile, comprises the differential mechanism as above described in any one.
The beneficial effects of the utility model are: differential mechanism of the present utility model, and its housing and gear ring adopt spline joint, and compare the friction torque transmitting torque adopting bolt presses to produce, shearing force can transmit more high pulling torque.This structure adopts spline joint, can remove 8 bolts, and gear ring lower thickness, realizes differential mechanism lightweight, reduce cost simultaneously simultaneously.
Accompanying drawing explanation
Fig. 1 represents the surface structure schematic diagram of differential mechanism in the utility model embodiment;
Fig. 2 represents the surface structure schematic diagram of the gear ring of differential mechanism in the utility model embodiment;
Fig. 3 represents the surface structure schematic diagram of the housing of differential mechanism in the utility model embodiment.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in detail.
With reference to shown in Fig. 1, Fig. 2 and Fig. 3, the utility model provides a kind of differential mechanism, comprises housing 1 and gear ring 2, and the outer surface of housing 1 arranges a circle external splines 101; Gear ring 2 comprises a mounting hole 201, and the inner hole wall of mounting hole 201 radially arranges internal spline 202; Housing 1 inserts in mounting hole 201 along the axis of gear ring 2, and external splines 101 engages with internal spline 202, and housing 1 is fixed with gear ring 2.When housing 1 inserts in mounting hole 201 along the axis of gear ring 2 specifically, together with the external splines 101 that the outer surface of housing 1 is arranged can tightly engage with the internal spline 202 that mounting hole 201 inwall is arranged, so just achieve fixing of housing 1 and gear ring 2.Because housing 1 and gear ring 2 adopt spline joint, compare the friction torque transmitting torque adopting bolt presses to produce, shearing force can transmit more high pulling torque, decreases the use of bolt, realizes differential mechanism lightweight, reduces cost simultaneously.
External splines 101 arranges one week along the outer surface of housing 1; Internal spline 202 arranges one week in inner ring 212.Like this, when internal spline 101 and external splines 202 coordinate, more point of contact can be provided, thus more high pulling torque can be transmitted.
Furthermore, gear ring 2 comprises outer ring 211 and inner ring 212, and outer ring 211 and inner ring 212 are arranged with one heart, and outer ring 211 is compared with the axle center of inner ring 212 away from gear ring 2, and the thickness of outer ring 211 is greater than the thickness of inner ring 212.Outer ring 211 can be structure as a whole in inner ring 212, adopts casting or turning etc. to process, also by outer ring 211 and inner ring 212 split manufacture, then can weld.These are only in the present embodiment, to the citing of inner ring and outer ring processing mode, but processing method is not limited to above-mentioned explanation.Ring gear machining is become the concentric structure arranged of external toothing 211 and ring gear 212, one is be conducive to ring gear processing spline, and two is the demands meeting assembling.Wherein, internal spline 202 is arranged on inner ring 212.
As the preferred scheme of one, external splines 101 and internal spline 202 are rectangular spline, and rectangular spline has the stressed feature such as large of easy processing, transmission.Certainly, be suitable for external splines and internal spline with the use of other forms of spline also in protection domain of the present utility model, in this citing that differs.
The utility model additionally provides a kind of automobile, comprises the differential mechanism as above described in any one.
It should be noted that, this automobile is the automobile comprising above-mentioned differential mechanism, and the implementation of above-mentioned differential mechanism embodiment is equally applicable in the embodiment of this automobile, also can reach identical technique effect, not repeat them here.
Above-described is preferred implementation of the present utility model; should be understood that the ordinary person for the art; can also make some improvements and modifications not departing under principle prerequisite described in the utility model, these improvements and modifications are also in protection domain of the present utility model.
