Root axis is successively threaded onto four circular holes of four planetary gears, four planet gear pads and differential case assembly respectively；It is described
The middle part of straight pin is fixedly connected with the radial through-hole of cross axle, and the end of the straight pin is total with the semiaxis of insertion two sides respectively
At end face, the spline fitted of the splined shaft of half axle assembly and the axle shaft gear, the axle shaft gear and planetary gear
Engagement.
Preferably, the central through hole across the cross axle of the straight pin, and the central axes of the two intersect vertically.
Preferably, it is provided with a radial through-hole on the straight pin, a radial blind holes are provided on the cross axle, elasticity
Straight pin is inserted into the radial blind holes and the radial through-hole, for fixing the cross axle and and the straight pin.
Preferably, half axle assembly is made of half shaft body with bushing, the end of half shaft body of indentation of the bushing
Face circular hole, the straight pin and bushing cooperate.
Preferably, the end face of flange and wheel hub of half shaft body are spirally connected by bolt.
Preferably, the cross axle outer diameter promotes greasy property as oil duct using the axisymmetric flat structure of milling.
The beneficial effects of the utility model are: by increasing above-mentioned guide frame in splined shaft one end of floated semiaxis,
Keep its transmission more stable, transmission efficiency is higher, reduces differential mechanism abnormal sound and occurs, improves the differential function of driving vehicle bridge.
