Description
Technical field
The utility model is related to a kind of automobile differential mechanisms, more particularly, to a kind of welding hybrid power differential casing.
Background technology
Domestic car and other class automobiles all use symmetrical bevel gear open differential substantially at present.Symmetrical expression cone tooth
Differential mechanism is taken turns by planetary gear, planetary gear shaft（Cross axle or a direct selling axis）With the compositions such as differential casing.Planetary gear
Axis is mounted in the corresponding planet hole of differential casing, is cased with sliding bearing on the axle journal of differential mechanism both ends respectively, is equipped in shell
Planetary gear, planetary gear are assemblied in planet axis.Planet axis both ends are equipped with jump-ring slot, and differential casing is stuck in two clamp springs
On planet outer end of hole face, planet axis axial float is prevented.It is planetary each side with a straight bevel axle shaft gear
It is meshed.The axle journal of axle shaft gear is supported in the corresponding hole of differential casing or so, and internal spline is connected with semiaxis, with differential
The planetary gear that device shell rotates together stirs the axle shaft gear rotation of both sides, suffered by the wheel of both sides when resistance difference, planet
Gear also passes through the differential driving realized around one rotation of own axis to both sides wheel.But current differential casing needs
It to be attached using bolt, structure is complex, and production cost is higher, and quality is more unstable, can cause safety accident.
Utility model content
The utility model is to provide a kind of welding hybrid power differential casing, mainly solves present in the prior art
Differential casing need to be attached using bolt, structure is complex, and production cost is higher, and quality is more unstable, can draw
Send out the technical problem of safety accident etc..
The above-mentioned technical problem of the utility model is mainly to be addressed by following technical proposals：
The welding hybrid power differential casing of the utility model, including enclosure body, the middle part of the enclosure body
Equipped with the big fenestra for installing planetary axle shaft gear, big fenestra side be equipped with mutually matched driven wheel of differential construction section and
Be screwed section, and the other side is equipped with retainer plate, and enclosure body is equipped with annular solid, and the outer surface of annular solid is welded equipped with driven gear
Access slot.Entire differential casing is that integral type is cast, and groove can be equipped in the section that is screwed, is convenient for lubrication and oil storage,
It can coordinate with the hybrid power of pony car, prevent the phenomenon that front and rear housings is detached from, improve its security performance.In ring
The outer surface of body is equipped with driven gear welding groove, and driven gear is welded on poor shell, and difference is fixed by bolts to change
Traditional connecting mode on fast device shell, have it is simple in structure, it is at low cost, the characteristics of stable quality.
Preferably, the annular solid outer end face of the driven gear welding groove both sides is respectively equipped with inclined-plane, chamfering.Welding
Place is open using gradient, is eliminated and is most also easy to produce weld defect at beginning solder joint and welding end point.
Preferably, being equipped with spherical wear-resisting ring in the big fenestra.Big fenestra and spherical wear-resisting ring coordinate, and make its structure
Simply, fitting tight.
Preferably, strengthening groove is provided on the inner wall of the section that is screwed, embedded with reinforcement alloy-layer in strengthening groove.
It can be reinforced entirely being screwed the bonding strength of section by reinforcing alloy-layer, to be produced fracture when ensureing connection.
Preferably, being provided with the groove that section is bowl-type on the end face of the annular solid.It on the one hand can be with by groove
Material is saved, production cost is reduced, on the other hand can position.
Therefore, the utility model on differential casing using driven gear welding groove is processed, so as to directly weld
Driven gear is connect, eliminates the mode being connected in this way, reduces production cost, it is simple and reasonable for structure.
