Abstract
The utility model relates to a flange type internal constant-velocity joint, which comprises a bell-shaped casing and an assembly, wherein an opening of the inner wall of the bell-shaped casing is provided with chamfer angles, the inward portion of the opening of the inner wall of the bell-shaped casing of the internal CV joint is parallel to a center axis of the internal CV joint, and a flange is arranged at the rear of the bell-shaped casing. The assembly can freely move axially in the bell-shaped casing, axial angles of an input shaft and an output shaft are changed, and shaft interval can be changed to some degree so as to be adaptive to conditions that a power output component and a power input component shift axially. The chamfer angles bring convenience for the output shaft to transmit torque flexibly. The bell-shaped casing is firmly connected with the input shaft by aid of the flange structure at the rear of the bell-shaped casing.
Description
Technical field
The utility model relates to a kind of transmission device, relates in particular to the universal joint flange-type 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, adopts axle to be fixed in the way at outer race rear portion under the general case, can make the connection part of axle and outer race become the weakness of assembly, thereby influence the product bulk life time
The model utility content
The purpose of this utility model is 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 flange-type 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 outer race rear portion also is provided with flange.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; The flange arrangement at outer race rear portion makes outer race quite firm with being connected of input shaft.
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 outer race rear portion also is provided with bonnet.The impurity such as dust that can reduce the external world that are provided with of bonnet enter outer race inside, and protection transmission position increases its life-span.
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, improve the bearing capacity at transmission position on the basis in three balls and three-flute design space in making full use of outer race, simplify technology simultaneously, improved the working life of parts.
3, it is quite firm that flange arrangement makes the connection of transmission part, and bearing capacity is strong, and the life-span is long.
Description of drawings
Fig. 1 is the utility model structure internal anatomy;
Among the figure, 1, outer race, 2, assembly, 3, bonnet.
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 built-in type internal spherical cage comprises outer race 1, assembly 2, described outer race 1 inwall and outer race central axes are provided with three grooves, and the internal surface opening is provided with chamfering, the internal surface rear portion also is provided with bonnet 3, and outer race 1 rear portion also is provided with flange; Described assembly 2 can be made axial free movement in described outer race 1 inside, is provided with three balls in the described assembly 2, is loaded in three grooves of outer race 1 internal surface.
During work, the flange of power input shaft fixedly is loaded on the flange at outer race 1 rear portion, the assembly 2 center fixation pto of packing into, when input shaft rotates, drive outer race 1 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 1 inner surface axial, so the angle between output shaft and the input shaft and spacing all can change.
Claims (3)
1. a flange-type internal spherical cage comprises outer race, assembly, it is characterized in that: 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 outer race rear portion also is provided with flange.
2. according to the described a kind of flange-type internal spherical cage of claim 1, it is characterized in that: 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.
