Have with the one-to-one mounting hole one of left-handed planetary gear, the left-handed planetary gear be placed in corresponding mounting hole one and simultaneously with the right side
Sun gear engagement is revolved, the right side of the differential casing has and the one-to-one mounting hole two of dextrorotation planetary gear, the dextrorotation
Planetary gear is placed in corresponding mounting hole two and engages simultaneously with left-handed sun gear, the left-handed sun gear and dextrorotation sun gear it
Between be connected and have a support sleeve, the inner end of the left-handed planetary gear and the inner end of dextrorotation planetary gear are respectively provided with a locating shaft,
It is arranged with a bearing on the locating shaft, is bolted between the outer ring and support sleeve of the bearing.
Working principle: the internal spline that is punched through of left-handed sun gear and dextrorotation sun gear wears corresponding two transmission shafts,
When automobile straight-line travelling, left-handed planetary gear and dextrorotation planetary gear not rotation, only too around corresponding left-handed sun gear and dextrorotation
The center revolution of sun wheel generates rotational speed difference when automobile turns round, if right end wheel drives dextrorotation sun gear to rotate, dextrorotation
Sun gear drives the left-handed planetary gear rotation in the same end, and left-handed planetary gear drives other end dextrorotation planetary gear to rotate again, dextrorotation row
Star-wheel drives left-handed sun gear to rotate again, realizes rotational speed difference.
It is connected by the way that each left-handed planetary gear and dextrorotation planetary gear are passed through bearing respectively with support sleeve, left-handed planetary gear and a left side
It can pass through axis between end cap and differential casing, between dextrorotation planetary gear and right end cap and differential casing with preset clearance
Hold and be supported with bolt, thus make left-handed planetary gear and dextrorotation planetary gear realize the abrasion that bearing is only existed without abrasion and with
Meshing wear between two sun gears, substantially increases the stationarity of differential mechanism, reduces abrasion and the generation of frictional heat, mentions
The high performance of differential mechanism, to make the service life of differential mechanism extend, maintenance cost reduces, maintenance period extension.
There is a connection in a kind of above-mentioned planetary gear Torsen formula differential mechanism without abrasion, on the outer ring of the bearing
Hole has on the support sleeve and each left-handed planetary gear and the one-to-one threaded hole of dextrorotation planetary gear, bolt spiral shell simultaneously
Line connection screw thread hole and connecting hole.
The dismounting between support sleeve and left-handed planetary gear and dextrorotation planetary gear in this differential mechanism is very convenient, first will be left-handed
Planetary gear and dextrorotation planetary gear are inserted into respectively in mounting hole one and mounting hole two, then by rotating left-handed planetary gear and dextrorotation row
Star-wheel makes to be aligned between bolt and the connecting hole of bearing outer ring, can be completed installation, when dismounting direct demounting bolt, and
And
In a kind of above-mentioned planetary gear Torsen formula differential mechanism without abrasion, the left-handed planetary gear and dextrorotation planetary gear point
Not Ju there are four, and the two distributes alternately.
