As a kind of optimal way of the present utility model, at described planetary gear and described differential carrier
Being provided with planet gear pad between inwall, one end of planet gear pad is resisted against described differential carrier
On inwall, the other end is resisted against on described planetary gear.
As a kind of optimal way of the present utility model, described locating part includes collar, at described axis hole
Inside being provided with draw-in groove, be provided with first annular groove on described wheel shaft, the inner of collar is resisted against the first ring
In connected in star, the outer end of collar is resisted against in draw-in groove.
As a kind of optimal way of the present utility model, described wheel shaft is provided with the second annular groove,
Being provided with support seat at described axis hole, also include jump ring, the inner card of jump ring leans against in the second annular groove,
The outer end of jump ring is resisted against on support seat, and described axis hole is through to outer wall from the inwall of described differential carrier,
Described support seat is arranged on the outer wall of described differential carrier.
After using the technical solution of the utility model, each planetary gear is by an independent wheel shaft even
Connecing on the differential housing, relatively conventional cross axle structure, in this utility model, every wheel shaft is permissible

Detailed description of the invention
In order to the technical solution of the utility model is explained further, it is described in detail below in conjunction with the accompanying drawings.
Seeing figures.1.and.2, a kind of planetary mounting structure of Novel drive axle, including differential carrier
10, the axle shaft gear 20 being arranged in differential carrier 10 and the planet tooth coordinated with axle shaft gear 20
Wheel 30, axle shaft gear 20 is assemblied on semiaxis in use, and planetary gear 30 passes through wheel shaft 40 with poor
Speed device shell connects, and one end of wheel shaft 40 is connected with planetary gear 30, is provided with axle on differential carrier 10
Hole 50, the other end of wheel shaft 40 is connected on axis hole 50, is provided with restriction wheel shaft on wheel shaft 40
40 locating parts moved axially.
As a kind of optimal way of the present utility model, described planetary gear 30 is four, each planet
Gear 30 arranges a described wheel shaft 40, is correspondingly provided with four axis holes 50, often on differential carrier 10
A piece wheel shaft 40 of independent arranging on individual axis hole 50, the Axis Cross across at four wheel shaft 40 places,
But relative to traditional cross axle structure, every wheel shaft 50 of the present utility model is independently mounted at axis hole 50
In, every wheel shaft 40 can be separately machined, overcomes tradition cross axle machining accuracy demand height and installs
Troublesome shortcoming.
As a kind of optimal way of the present utility model, at described planetary gear 30 and described differential carrier
Being provided with planet gear pad 31 between the inwall of 10, one end of planet gear pad 31 is resisted against described
