Abstract
The utility model relates to the technical field of automobile drive accessories and provides an input and output structure of a drive axle assembly. The input and output structure of the drive axle assembly comprises an inner constant velocity universal joint, an outer constant velocity universal joint, an input main shaft, an output main shaft and a middle shaft, wherein the input main shaft is connected with the inner constant velocity universal joint, and the output main shaft is connected with the outer constant velocity universal joint. The front end of the input main shaft is provided with a bend with a degree of 30, a spline with a length of 25mm is arranged along the upper shaft direction of the input main shaft, the output main shaft is provided with a bend with a degree of 45, and a spline with a length of 26mm is arranged along the upper shaft direction of the output main shaft. The input and output structure of the drive axle assembly has the advantages that the entire drive axle assembly is applicable to conditions of large transmission angle and poor carrying capability, and defects of low strength, inapplicability to automobiles with high torque and difficult manufacturing process of the prior art can be solved, so that the purposes of the improvement of the overall strength and the operation stability are achieved.
Description
Technical field
The utility model belongs to Automobile drive accessory technical field, relates to the input/output structure in a kind of drive axle assembly.
Background technology
In order to make the automobile power transmission, all can use the drive axle assembly, adopting at present maximum is ball cage type drive axle assembly, has all solved preferably constant speed transmission problem no matter this kind drive axle assembly is circular arc alley or liner ball road, and it is large to transmit operating angle, and efficient is high.The shortcoming of the input/output structure in existing drive axle assembly be and can't adapt to the large situation of some driving angles, load-carrying capacity is poor, service life is short, and bearing load is also relatively poor, and manufacturing cost is higher.
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, and bearing load is good, the input/output structure in the drive axle assembly of assurance drive axle assembly operation stability.
the utility model solves the problems of the technologies described above the technical scheme that adopts: the input/output structure in a kind of drive axle assembly, comprise internal spherical cage, external ball cage, entering spindle, output main shaft and tween drive shaft, described entering spindle is connected with internal spherical cage, described output main shaft is connected with external ball cage, it is characterized in that, the leading section of described entering spindle has the curved angle that connects, the described curved angle that connects the angle is 30 degree, axially offer spline on described entering spindle, the length of described spline is 25mm, has the curved angle that connects on described output main shaft, the described curved angle that connects the angle is 45 degree, axially be shaped with spline on described output main shaft, the length of spline is 26mm.
Specifically comprise for optimizing the such scheme Adopts measure:
In input/output structure in above-mentioned a kind of drive axle assembly, described external ball cage has the housing of connection face with output between main shaft, and the thickness of described connection housing face is 54mm.
In input/output structure in above-mentioned a kind of drive axle assembly, the compression control of whole drive axle assembly is at 639.5+-3mm.
Compared with prior art, the utility model has the advantage of by the setting to entering spindle and output main shaft, make whole drive axle assembly adapt to the large situation of some driving angles, load-carrying capacity is poor, solved original techniques intensity lower, be not suitable for high moment of torsion vehicle, the defective that manufacturing process is high has realized the raising bulk strength, promotes the purpose of operation stability.
