Abstract
The utility model belongs to the technical field of mechanical parts, and provides an inner spherical cage of a driving shaft assembly. The inner spherical cage of the driving shaft assembly comprises an input connecting shaft, a shell and a spherical cage assembly. The spherical cage assembly receives power of the input connecting shaft and outputs the power onto an outer spherical cage. The input connecting shaft comprises a spline portion, a middle connecting portion and a shell connecting portion, wherein the spline portion, the middle connecting portion and the shell connecting portion are sequentially connected. A bearing pedestal is arranged on the shell connecting portion. A containing groove is formed by the bearing pedestal and the shell connecting portion. A bearing is arranged inside the containing groove. A step flange is arranged on the bearing pedestal. A matching groove is formed between the bearing pedestal and the shell. The inner spherical cage of the driving shaft assembly has the advantages that due to the fact that the structure of the input connecting shaft is improved, connection between the input connecting shaft and an engine gearbox is more reliable and stable, meanwhile, tight fit between the inner spherical cage and other parts can be achieved, it is ensured that changes of a transmission angle are large, the spherical cage assembly is not easily disengaged, the inner spherical cage can be suitable for the complex road surface state, and the bearing capacity is higher.
Description
Technical field
The utility model belongs to mechanical fitting technical field, relates to a kind of internal spherical cage of drive shaft assembly.
Background technique
In order to make automobile power transmission, all can use drive shaft assembly, adopting at present maximum is Rzeppa type drive shaft assembly, no matter this kind of drive shaft assembly is that circular arc alley or liner ball road have all solved constant speed transmission problem preferably, and it is large to transmit operating angle, and efficiency is high.Automobile on the way travels, and the situation of encountering is quite complicated, and the input end of the internal spherical cage in present drive shaft assembly is many with other parts interference when mounted, has so just affected the transmission of power, cannot guarantee the normal use of drive shaft assembly when serious.
Summary of the invention
Technical problem to be solved in the utility model is the present situation for prior art, and provides a kind of simple in structure, the internal spherical cage of the drive shaft assembly that bearing capacity is strong.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of internal spherical cage of drive shaft assembly, comprises with lower member:
Input coupling shaft, for engine mission and receive power;
Ball cage assembly, described ball cage assembly receives the power of input coupling shaft and exports on external ball cage;
Housing, the coated whole ball cage assembly of described housing also provides working space for ball cage assembly;
It is characterized in that: described input coupling shaft comprises and connects successively spline part, middle interconnecting piece and housing joint, on described housing joint, be provided with bearing support, be formed with containing groove at bearing support and housing joint, in containing groove, be provided with bearing, on described bearing support, there is step rib, between bearing support and housing, there is mating groove.
The measure of taking for optimization such scheme specifically comprises:
In the internal spherical cage of above-mentioned a kind of drive shaft assembly, on described middle interconnecting piece, be provided with flour milling fixed block, on flour milling fixed block, be provided with back-up ring.
Compared with prior art, the utility model has the advantage of by the structure of input coupling shaft is improved, making like this to input coupling shaft is connected with engine mission more reliable and stable time, also can closely cooperate with other component, guarantee that driving angle changes greatly, ball cage assembly is also not easy to come off, and can adapt to complicated pavement state, and bearing capacity is also stronger.
Accompanying drawing explanation
Fig. 1 is the structural representation of the internal spherical cage of this drive shaft assembly.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
