Abstract
The utility model relates to a double-spline structured input shaft inner ball cage, which comprises a bell-shaped shell and an assembly, wherein the open position of the inner wall of the bell-shaped shell is provided with a chamfer, and the inward part of the open position of the inner wall of the bell-shaped shell is parallel to the central axis of the inner ball cage; the back of the assembly is also provided with a spring, the front end of the spring is connected with the back of the assembly, and the back end thereof is connected with the bottom of the inner surface of the bell-shaped shell. The assembly can freely move in the axial direction of the bell-shaped shell, can not only lead the input shaft and the output shaft to have a certain change in the axial angle, but also lead the distance between axles to have a certain change to adapt to the condition that a power output part and a power input part have displacement in the axial direction; and the arrangement of the chamfer facilitates the flexible torque transfer of the output shaft.
Description
Technical field
The utility model relates to a kind of transmission device, relates in particular to the universal joint honeysuckle bond structure input shaft internal spherical cage of automobile.
Background technique
For making the automobile power transmission, no matter be forerunner or rear-guard, or use independent suspension, all can use universal joint, what employing was maximum at present is rzeppa universal joint, all solved constant speed transmission problem preferably no matter this kind universal joint is circular arc alley or liner ball road, and it is big to transmit operating angle, the efficient height.But automobile on the way travels, the situation of running into is quite complicated, universal joint as actuating unit not only needs working stability, efficient height, also need to adapt to more complicated transmission situation, present universal joint can only make universal joint do certain change on driving angle with the ball cage, can not adapt to more complicated situation.
Simultaneously, the effect of ball cage has determined its significance, and the connection of axle is also quite important, and single spline shows slightly thin, and is unable to do what one wishes a bit when facing high pulling torque.
The model utility content
The purpose of this utility model provides a kind of working stability, efficient height, effective, transmission version universal joint internal spherical cage how.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of honeysuckle bond structure input shaft internal spherical cage, comprise outer race, assembly, described outer race inwall opening is provided with chamfering, and inside part of the opening of internal spherical cage outer race inwall and internal spherical cage central axes; Described assembly rear portion also is provided with spring, and described spring front end is connected in the rear portion of described assembly, and the rear end is connected in the bottom of described outer race internal surface.Assembly can make input shaft and output shaft not only at axial angle certain change be arranged at the outer race axial free movement, also can make distance between shafts also do certain change, to adapt to the situation that power output part and power input part axially are subjected to displacement; Being provided with of chamfering makes things convenient for output shaft flexible communication moment of torsion.
As preferably, described outer race rear portion also is provided with coupling shaft, and the front end of described coupling shaft is fixed on the rear portion of described outer race, and middle-end and rear end are respectively equipped with one group of axial splines structure and one group of oblique spline structure.Axial splines and oblique spline are used for this kind universal joint internal spherical cage is fixed in input shaft; The spline that two kinds of different direction are set make between internal spherical cage and the input shaft be connected more firm, transmitting torque and motion better.
As preferably, described assembly comprises three balls, retainer and star sleeves, and described star sleeve outer surface is provided with three grooves, and described outer race internal surface is provided with three grooves.Three balls and three grooves can make torque drive reach effect preferably, and quantity reduces then transmission position stress ability to bear deficiency, than fragile under the high pulling torque; Quantity reduces, and the size of then corresponding ball and groove is inevitable also to be reduced, and has reduced the stress ability to bear at transmission position equally.
As preferably, described assembly rear portion also is set with spring cup, and described spring front end is arranged in the spring cup, and is connected on the described assembly by spring cup.Being provided with of spring is beneficial to the utility model and adapts to the situation that power output part and power input part axially are subjected to displacement better.
In sum, the utlity model has following beneficial effect:
1, assembly can be done axial motion in outer race, makes not only can change axial angle between power input shaft and the output shaft, can also do the change of axle base within the specific limits, makes more complicated situation of universal energy-conservation adaptation;
2, the Rzeppa type structure makes that the transmission of universal joint constant speed is effective, the transmission operating angle is big, efficient is high, and bearing capacity is strong.
3, the spline that two kinds of different direction are set make between internal spherical cage and the axle be connected more firm, transmitting torque and motion better.
Description of drawings
Fig. 1 is the utility model anatomical structure figure;
Among the figure, 2, assembly, 3, spring cup, 4, spring, 5, outer race.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
This specific embodiment only is to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make the modification that does not have creative contribution to present embodiment as required after reading this specification, but as long as all are subjected to the protection of Patent Law in claim scope of the present utility model.
Embodiment 1
As shown in the figure, a kind of honeysuckle bond structure input shaft internal spherical cage, comprise outer race 5, be provided with assembly 2 in the outer race 5, the assembly rear portion is provided with spring cup 3, be provided with spring 4 in the middle of spring cup 3 and the outer race 5 internal surfaces bottom, assembly 2 inside are provided with three balls, the central axes of outer race 5 internal surface internal surfaces and outer race 5, and the internal surface opening is provided with chamfering, internal surface also is provided with three grooves, and three balls of assembly 2 inside are loaded in three grooves of outer race 5 internal surfaces.
During work, fixedly be loaded on the axle at outer race 5 rear portions on the power input shaft, the assembly 2 center fixation pto of packing into, when input shaft rotates, drive outer race 5 and do the same angular velocity rotation, because the screens of three grooves and spin, assembly 2 drive output shafts and make same angular velocity and rotate, finish the transmission of power.Assembly 2 can be done unrestricted motion at outer race 5 inner surface axials, so the angle between output shaft and the input shaft and spacing all can change.
Axial splines and oblique spline are used for this kind universal joint internal spherical cage is fixed in input shaft; The spline that two kinds of different direction are set make between internal spherical cage and the input shaft be connected more firm, transmitting torque and motion better.
