Abstract
The utility model relates to a shift shaft assembly for a speed changing box. The shift shaft assembly comprises a main body and a gear shifting finger. The gear shifting finger comprises a first gear shifting finger and further comprises a shaft sleeve, wherein the first gear shifting finger is embedded at one end of the main body and integrated with the main body, the shaft sleeve sleeves one end, far away from the first gear shifting finger, of the main body, and the shaft sleeve is fixedly connected with the main body. As the practical scheme, the shift shaft assembly further comprises a second gear shifting finger which is embedded on the outer wall of the shaft sleeve and integrated with the shaft sleeve. In addition, the shift shaft assembly further comprises a gear shifting block which is formed by a punched sheet, a gear selecting block and a guide groove, wherein the gear shifting block, the gear selecting block and the guide groove are respectively welded on the outer wall of the shaft sleeve. The main body and the shaft sleeve are precision castings. The main body and the gear shifting finger are integrally designed, so that on the gear shifting finger structures are avoided, the number of product parts is reduced, and the number of management points in a manufacturing process is directly reduced. Meanwhile, the integrated structure also solves the problem of tolerance accumulation caused by match between the parts, and accordingly the quality of the shift shaft assembly of the speed changing box is more stable.
Description
Technical field
The utility model relates to a kind of gearbox selector shift shaft assembly, is mainly used in automobile gearbox inside, belongs to the vehicle transmission technical field.
Background technique
At present on market for gear selecting shifter assemblies in the control gear of automobile gearbox, the following two kinds of structures of general employing: the one, main body is by the moulding of a slice metal plate punching, again functor such as gear shift are referred to, the mechanism such as gear selecting piece, guiding groove is welded on the main body, but this complex structure, moulding is difficult, and quality is also unstable.The 2nd, main body is welded into integral body by two or the moulding of multi-disc metal plate punching with these panel beatings, functor such as gear shift is referred to, the mechanism such as gear selecting piece, guiding groove is welded on the main body again.But this structure is by some panel beating welding, can have the problem of tolerance stack, and simultaneously, management point can increase to some extent when making this structure of production, and quality is just more difficult control also.
Above two kinds of structures all need to increase in addition additional mechanism providing additional operation, the demand that cooperates with central shaft in the controller of gear-boxes to satisfy main body, and additional matching mechanism need to refer to realize in gear shift mostly, therefore the structure that just causes gear shift to refer to is more complicated, and technology difficulty and technological requirement are also just higher.
How to satisfy simply and easily the requirement of gearbox selector gear shift, how to promote the stability of part quality, complexity and the technology difficulty that the reduction gear shift refers to mechanism, become the main direction that industry is studied.
The model utility content
The gearbox selector shift shaft assembly that the utility model provides a kind of automobile to use can satisfy gearbox selector gear shift requirement easily, reduces the complex process degree of this assembly in making course of working.
In order to realize the purpose of this utility model, the utility model provides a kind of gearbox selector shift shaft assembly, comprise that main body and gear shift refer to, described gear shift refers to comprise that the first gear shift refers to, it is characterized in that, described the first gear shift refers to be embedded the end in described main body, and described main body and described the first gear shift refer to be wholely set.
As one of preferred version, it also comprises and is set in the axle sleeve that refers to an end on the main body away from the first gear shift, itself and the welding of described main body.
As a kind of possible technological scheme, described gear shift refers to also comprise that the second gear shift refers to, described the second gear shift refers to be embedded at the outer wall of described axle sleeve, and is wholely set with described axle sleeve.
Say further, the utility model, it also comprises a shift block, a gear selecting piece and a guiding groove, described shift block, described gear selecting piece and described guiding groove are separately fixed on the outer wall of described axle sleeve.
As one of preferred technological scheme, described shift block, described gear selecting piece and described guiding groove are metal plate punching spare.
As one of preferred technological scheme, described main body and described axle sleeve are precision castings.
Compared with prior art, the utility model has following advantage at least: in this gearbox selector shift shaft assembly, main body and gear shift refer to Integral design, perhaps a plurality of gear shift refer to be wholely set with main body and axle sleeve respectively, need not to establish in addition gear shift and refer to, can reduce the number of spare parts of product, directly reduce the quantity of the management point in the manufacture process, simultaneously, the structure that is wholely set has also been eliminated each component and has been cooperated the tolerance build-up problem that produces, so that the quality of this gearbox selector shift shaft assembly is more stable.
