Abstract
The utility model relates to a planet set for an automatic transmission. The planet set comprises a planet gear and a planet carrier. A planet axle is arranged on the planet carrier, the planet gear is arranged on the planet axle, a rear end cover is arranged at the rear end of the planet set, four grooves are arranged on the planet carrier, are positioned on one side of the rear end cover and are arranged on inner sides of holes of the planet axle, seam allowance is reserved at a joint of the rear end cover and the planet axle, and the planet axle can bear leftward axial force. The planet set has the advantages that the four grooves are arranged on the planet carrier, are positioned on the side of the rear end cover and are arranged on the inner sides of the holes of the planet axle, and the planet axle can bear rightward axial force; and a part, which is positioned on one side of the rear end cover, of the planet axle is protected during heat treatment, so that the corresponding end of the planet axle can deform after being stressed and then can be fittingly riveted with the grooves, and the planet set is simple in assembly and low in production cost.
Description
Technical field
The utility model relates to a kind of planet row, is applicable to automatic transmission, specifically, relates to a kind of automatic transmission and arranges with planet, belongs to field of mechanical technique.
Background technique
In multi-speed automatic transmission, has the planet row of different structure form.At present, among the planet of the traditional speed changer row, adopt fixedly planet wheel shaft of the mode of riveting at the planet wheel shaft two ends or adding positioning pin hole at planet wheel shaft usually.
In realizing process of the present invention, the inventor finds to exist at least in the prior art following problem, adopts fixedly planet wheel shaft of above riveted joint mode at the planet wheel shaft two ends, can cause the planet carrier distortion; The mode that adopts draw-bore at planet wheel shaft is planet wheel shaft fixedly, can increase the difficulty of processing and assembling, causes the cost increase of its gearbox.
The model utility content
The technical problems to be solved in the utility model is at above deficiency, provide a kind of automatic transmission to arrange with planet, overcome and caused the defective that planet carrier is out of shape, assembling difficulty is big, cost of production is high in the prior art easily, adopt automatic transmission of the present utility model to arrange with planet, have the advantage that assembling is simple, cost of production is low.
For solving the above problems, the utility model is by the following technical solutions: a kind of automatic transmission is arranged with planet, comprise planet wheel, planet carrier, planet carrier is provided with planet wheel shaft, planet wheel is arranged on the planet wheel shaft, planet row's rear end is provided with rear end cover, and it is characterized in that: the planet carrier of described rear end cover one side is provided with four grooves, and groove is arranged on the inboard of planet wheel axis hole.
A kind of optimized project, the joint of described rear end cover and planet wheel shaft is provided with seam.
The utility model is taked above technological scheme, compared with prior art, has the following advantages: the joint of rear end cover and planet wheel shaft is provided with seam, and planet wheel shaft can bear axial force left; The planet carrier of rear end cover one side is provided with four grooves, and groove is arranged on the inboard of planet wheel axis hole, and planet wheel shaft can bear axial force to the right; The planet wheel shaft of rear end cover one side is protected when heat treatment, cooperates so that its end can be out of shape after stressed with the groove riveted joint, and assembling simply, cost of production is low.
The utility model is described in further detail with enforcement below in conjunction with accompanying drawing.
Description of drawings
Accompanying drawing 1 is the structural representation of planet row among the utility model embodiment;
Accompanying drawing 2 is the left view of accompanying drawing 1;
Accompanying drawing 3 is the partial enlarged drawing of rear end cover, planet carrier in the accompanying drawing 1;
Among the figure,
The 1-planet wheel, 2-planet carrier, 3-planet wheel shaft, 4-pad, 5-bearing, 6-rear end cover, 7-groove, 8-seam.
Embodiment
Embodiment, as Fig. 1, Fig. 2, shown in Figure 3, a kind of automatic transmission is arranged with planet, and planet wheel 1, planet carrier 2 are drawn together in the planet package, planet carrier 2 is provided with planet wheel shaft 3, planet wheel 1 is arranged on the planet wheel shaft 3, is provided with bearing 5 between planet wheel shaft 3 and planet wheel 1, and the two ends of planet wheel 1 are respectively equipped with pad 4, planet row's rear end is provided with rear end cover 6, rear end cover 6 is provided with seam 8 with the joint of planet wheel shaft 3, and like this, planet wheel shaft 3 can bear axial force left.
The planet carrier 2 of rear end cover 6 one sides is provided with four grooves 7, and groove 7 is arranged on the inboard of planet wheel axis hole, and like this, planet wheel shaft 3 can bear axial force to the right.
The planet wheel shaft 3 of rear end cover 6 one sides is protected when heat treatment; cooperates in order to can be out of shape after its end is stressed with groove riveted joint, planet wheel shaft is carried out axial restraint locate, can flange increase to the material of groove 7; strengthen ability to bear, improved safety coefficient.
Those skilled in the art will recognize that; above-mentioned embodiment is exemplary; be in order to make those skilled in the art can better understand the utility model content; should not be understood as the restriction to the utility model protection domain; so long as the improvement of doing according to technical solutions of the utility model all falls into protection domain of the present utility model.
