Abstract
The utility model discloses a 485 driven spiral bevel gear of series combination forging, its characterized in that: differential mechanism casing on one side of including driven spiral bevel gear and being located the gear, driven spiral bevel gear and be located as an organic wholeization of the differential mechanism casing forging structure of gear one side, the passive bevel gear combination forging of this 485 series with driven spiral bevel gear and be located as an organic wholeization of the differential mechanism casing forging structure of gear one side, are compared with prior art, comprehensive cost reduces, has the advantage that intensity is good, longe -lived, the car handling capacity is strong, the lightweight is good.
Description
Technical field
The utility model relates to a kind of 485 serial driven helical bevel gears combination forging, it is characterized in that: driven helical bevel gear and be positioned at the integrated forging structure of differential casing of gear side.
Background technique
Helical bevel gear is the key components and parts of automobile drive axle transmission system.In Automobile Transportation process, bear and underspeed, increase moment of torsion, and change the effect in transmission of torque direction.The operating conditions of the helical bevel gear of main reducing gear of drive axle is quite severe, compared with other gears of power train, has that load is large, a feature such as long action time, change are many, carrying impact.
The helical bevel gear of main reducing gear has two effects, and first is change the direction of power transmission, and second is provide a common velocity ratio as each gear that extends to of speed changer.The output of speed changer is the moment around vertical axes, and wheel must rotate around the transverse axis of vehicle, and this just needs a device to change the transmission direction of power.Why be main reducing gear, be exactly because no matter speed changer is on what gear, the velocity ratio of this device is all a factor of resultant gear ratio.Had this velocity ratio, can effectively reduce the requirement of the slowing down power(SDP) to speed changer, the benefit of design is like this size that can effectively reduce speed changer, makes the general arrangement of vehicle more reasonable.
The topmost effect of automobile main reducer is exactly that deceleration increasing is turned round.We know that the output power of motor is certain, the formula W=M*v(power=moment of torsion * speed according to power), after transmission speed being lowered by main reducing gear, can higher output torque be obtained, thus obtain larger driving force.In addition, automobile main reducer also change Power output direction, realized the differential function of left and right wheels differential or middle back axle by differential mechanism.
Existing ransaxle transmission system mainly comprises two-part, one be main reducing gear, two is differential mechanisms, the transmission of both power is, by bolt, the housing of the driven helical bevel gear of main reducing gear and differential mechanism is carried out bolton connection, differential mechanism rotating is driven by driven helical bevel gear, thus the change in the direction of the transmission of realizable force and power.
This kind of mode brings following problem:
Because both are connected by bolt, its intensity is because above-mentioned Placement receives impact, therefore in order to meet the demands, not only will the helical bevel gear of main reducing gear do do greatly thick, and this kind of mode also increases the weight of differential casing undoubtedly, is unfavorable for the passing capacity of vehicle and further realizes lightweight.
In order to strengthen intensity and the bearing capacity of the helical bevel gear of main reducing gear, external diameter and the thickness of driven helical bevel gear can only be increased, also increasing size and the weight of ransaxle, and reducing the passing capacity of automobile.
And the differential casing be bolted with driven helical bevel gear, body is cast structure, and its production technology determines can there be trachoma in housing, and once after having trachoma, has a strong impact on the working life of differential mechanism, and then affects the life-span of car load.
Summary of the invention
For solving the technical problem of above-mentioned existence, the utility model provides a kind of 485 serial driven helical bevel gear combination forging, this 485 serial passive bevel gear combination forging, by driven helical bevel gear and the integrated forging structure of differential casing being positioned at gear side, compared with prior art, overall cost reduces, and has the advantage that intensity is good, the life-span long, automobile passing capacity is strong, lightweight is good.
For achieving the above object, the technological scheme that the utility model adopts is:
A kind of 485 serial driven helical bevel gears combination forging, comprise driven helical bevel gear and are positioned at the differential casing of gear side, described driven helical bevel gear and be positioned at the integrated forging structure of differential casing of gear side.
Preferably, described driven gear is driven helical bevel gear.
The utility model has abandoned original split modular structure, helical bevel gear and differential casing has been carried out forging integrated design, by forging the combination forging directly forging 485 serial driven helical bevel gears and differential carrier.
This shows with novel beneficial effect:
1, intensity is higher: integral structure of the present utility model is compared to original split-type structural, and its intensity is higher, can better meet the requirement of strength of car transmissions.
2, lightweight is good: compared with original structure, and the structure of this integration can save more than 40% in weight and volume.
3, the life-span is longer: compared with original cast structure, avoids the defect of trachoma, there will not be the phenomenons such as fracture.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
A kind of 485 serial driven helical bevel gear combination forging, comprise driven helical bevel gear 2 and are positioned at the differential casing 1 of gear side.
The 485 serial driven helical bevel gear combination forging of the present embodiment are formed by mould forging, the therefore helical bevel gear 2(gear of the present embodiment) and the integrated forging structure of differential casing 1, but not the structure of original bolton.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
