1. antiskid transfer case is made of one group of parallel shafts planetary differential, an interior diff, two bevel planet gear difies, one group of compound awl tooth diff;

  • It is characterized in that;

    One group of parallel shafts planetary differential is arranged on the middle part of part-time case housing, comprise a planet stent, a plurality of force transmission shafts are housed in that the circumferencial direction of planet stent is uniform, the two ends of each force transmission shaft fixedly have cylindrical planetary gear respectively, and differential casing gear I, the II with two ends realizes normal engagement respectively;

    Be provided with an interior diff at the middle part of pinion carrier, be fixed on the planet stent by first center cross, first center cross suit awl planetary wheel often meshes with solid axle side gear and hollow half axle gear respectively;

    Two bevel planet gear difies are separately positioned on the planet stent two ends, the bevel planet gear diff of one end is fixed on the housing gear I by second center cross, the awl planetary wheel of the second center cross suit often meshes with preceding solid axle side gear and inboard solid axle side gear respectively, driving gear is fixed together before preceding solid axle side gear and the preceding solid axle and first, driving gear and preceding passive tooth wheel shaft often mesh before first, drive front-wheel walking of car;

    The bevel planet gear diff of the other end is fixed on the housing gear II by the 3rd center cross, the awl planetary wheel of the 3rd center cross suit meshes with inboard hollow half axle gear, external hollow side gear shaft respectively, and the engagement of driving gear and shaft gear drives another front-wheel walking of car before the external hollow side gear shaft affixed second;

    The inboard solid axle side gear of the bevel planet gear diff at planet stent two ends and solid axle side gear are connected on the axle journal of a solid axle gear, and the solid axle gear often meshes with back passive tooth wheel shaft I and drives the walking of car one trailing wheel;

    Hollow half axle gear and inboard hollow half axle gear are connected, and are supported on the hollow half axle, and affixed rear drive gear II on the hollow half axle, rear drive gear II often mesh with back passive tooth wheel shaft II and drive another trailing wheel walking of car;

    Compound awl tooth diff is by the bearing pin uniform outer shroud that is contained in respectively, around the interior ring radial direction, in the double-deck awl of bearing pin spline upper sleeve dress planetary wheel is placed on, between the outer shroud, the tooth engagement of internal layer awl planetary wheel and a compound axle side gear side, outer knuckle-tooth and the rear drive gear II of compound axle side gear often mesh, the outer knuckle-tooth of the planetary one side of outer awl and conical gear engagement, conical gear is fixed on the power transmission housing, and an end of power transmission housing has one-way movement tooth and outer overriding clutch interlock, outer overriding clutch and shaft gear are nested together by free-sliding spline;

    The outer knuckle-tooth engagement of the planetary another side of outer awl axle side gear III, axle side gear III an end face one-way movement tooth arranged and be nested together by free-sliding spline with internal overrunning coupler interlock, internal overrunning coupler and shaft gear;

    In ring be fixed as one with passive tooth wheel shaft I, the ratio i of compound axle side gear and the rotating speed absolute value of axle side gear III is greater than 1/2nd, less than one;

    The preceding passive tooth wheel shaft related with solid semiaxis, back passive tooth wheel shaft I are diagonal line with respect to wheel and arrange;

    The shaft gear related with hollow half axle, back passive tooth wheel shaft II are diagonal line with respect to wheel and arrange.
