Technical field
The utility model relates to a kind of differential assembly, especially designs a kind of high strength low noise differential assembly installing pad after sun gear and planetary pinion additional.
Background technique
1, differential assembly is one of Chief part of haulage vehicle vehicle bridge, travels at normal vehicle.Often because road-surface problem and condition of road surface cause differential mechanism to break down, and the normal traveling of impact, particularly tempo turn is often because of meshing problem generation serious noise problem, even there is the irrational phenomenon of torque distribution, in running process, noise is very serious problem, affect driver and passenger's psychopathic disorder, easily cause the stability of automobile running.
2, due to differential casing material reason, cause differential casing to rupture, cause sun gear, planetary pinion, the damage parts such as planet pin, have a strong impact on vehicle and normally run.
Summary of the invention
For overcoming the deficiencies in the prior art, the utility model provides a kind of sun gear and planetary pinion to be in normal engagement with certain torque, reduces the gap of gears meshing, thus reduces the differential assembly of the noise of differential assembly.
For reaching above-mentioned target, the utility model by the following technical solutions:
A kind of high strength low noise differential assembly, comprises the left and right housing of differential mechanism; Respectively be provided with a sun gear in left and right housing, have cross planetary pinion between two sun gears, cross planetary pinion and two sun gears respectively gear teeth coordinate; Sun gear pad is equipped with at the sun gear back side, and sun gear pad is set on sun gear and between sun gear and corresponding housing, planet gear pad is equipped with at the planetary pinion back side.
Further, described planet gear pad is provided with two, and two planet gear pads connect respectively and are fixed on outside planetary middle part.
Further, described planet gear pad is arcuate structure.
Further, described planet gear pad sphere outer radius is R51 millimeter, and inside radius is 49 millimeters; Its material is that 65Mn is with steel, and hardness is 450 to 490HV.
Further, described differential casing material is high strength toughness cast condition ductile iron.
Further, the described sun gear number of teeth 16, modulus 5.5; The planetary bevel gear number of teeth 10, modulus 5.5.
Further, described sun gear gasket-end face tilt is arranged, 1.5 degree to 2 degree, angle of inclination; Its material is that 65Mn is with steel, and hardness is 450 to 490HV.
Working principle of the present utility model and beneficial effect show:
This differential mechanism is made up of parts such as planetary pinion, differential carrier, sun gears.
The power of motor enters differential mechanism through housing, Direct driver planetary wheel carrier, then drives left and right two sun gears by planet wheel, drives left and right wheel respectively.
The utility model is also equipped with sun gear pad at the sun gear back side, at the planetary pinion back side, planet gear pad is housed.Make sun gear and planetary pinion be in the state often combined, it acts on the elastic force of sun gear pad, planet gear pad, and the torque of its gears meshing is 10Nm to 35Nm.
Planet gear pad is provided with two and thinks corresponding with the inner ring of planetary outer ring and housing, and it is fixed and is connected on planetary pinion, easy for installation, be convenient to maintenance and change.
Sun gear pad is curved structure also, forms a kind of inside elastic pressure to sun gear, strengthens its engagement effect further.
Because differential casing is high strength toughness spheroidal graphite cast iron, when being subject to complex road surface and other unpredictalbe problem, the phenomenon of differential casing fracture can not be there is, thus embody the function of high strength differential mechanism.
