Description
Technical field
The utility model belongs to technical field of automobile parts, relates to a kind of big pivot angle constant velocity driving shaft assembly.
Background technique
In order to make the automobile power transmission; All can use drive shaft assembly, adopting maximum at present is the Rzeppa type drive shaft assembly, has all solved constant speed transmission problem preferably no matter this kind drive shaft assembly is circular arc alley or liner ball road; And it is big to transmit operating angle, and efficient is high.Automobile on the way goes, and the situation of running into is quite complicated, and present drive shaft assembly has just been done some variations on driving angle, and operating angle is little, and ball cage assembly comes off easily, can not adapt to complicated pavement state, and bearing capacity is also relatively poor.
Summary of the invention
The utility model technical problem to be solved is the present situation to existing technology, and provides a kind of simple in structure, and bearing capacity is strong, guarantees the big pivot angle constant velocity driving shaft assembly of operation stability.
The utility model solves the problems of the technologies described above the technological scheme that is adopted: a kind of big pivot angle constant velocity driving shaft assembly; Comprise internal spherical cage, ectosphere cage, input shaft, output shaft and jack shaft, described internal spherical cage and ectosphere cage interconnect through jack shaft, it is characterized in that; Described internal spherical cage comprises first housing, ball cage assembly and the first dustproof body; Described ball cage assembly is arranged in first housing, and described first dustproof body one end is connected on the jack shaft, and the other end is connected on the outer wall of first housing; Described ectosphere cage comprises second housing and is arranged on the retainer in second housing; Steel ball and star sleeve are equipped with seal ring on second housing, output shaft be provided with axial involute splines.
The measure of taking for the optimization such scheme specifically comprises:
In above-mentioned a kind of big pivot angle constant velocity driving shaft assembly; Described input shaft comprises spline part, intermediate portion and joint; Described spline part is connected through spline with the gear of gearbox; Joint stretches in first housing and is connected with ball cage assembly, and joint is provided with guard ring, on the input shaft near first housing, bearing is installed.Here can guarantee the bearing capacity of whole drive shaft assembly through bearing.
In above-mentioned a kind of big pivot angle constant velocity driving shaft assembly, the intermediate portion of described input shaft along the circumferential direction is evenly distributed with oblique oil groove.When input shaft rotated, the lubricant oil in the oil groove from moving to spline part, had guaranteed good lubricating effect along oblique oil groove.
In above-mentioned a kind of big pivot angle constant velocity driving shaft assembly, the joint of the described jack shaft and the first dustproof body, the second dustproof body is provided with clip.Here can guarantee that through clip dustproof body has certain resiliently deformable space, can increase the elastic force between dustproof body and the jack shaft again relatively.
Compared with prior art, the advantage of the utility model is to change operating angle arbitrarily, changes under the situation greatly in driving angle; Also can keep certain working stability, can adapt to complicated pavement state, and the constant speed transmission be effective; Axially involute splines and spline part have improved bearing capacity; Seal ring can be blocked in the pollutant of outside outside second housing, reduces wear, and has improved working life.
