Description
Technical field：
The utility model is related to the flexible constant velocity joint field of anti-dropout, specifically a kind of anti-dropout it is flexible etc.
Fast joint arrangement.
Background technology：
Existing flexible constant velocity joint, it is easy with three ball pin wheel hub connecting shafts in carrying or installation process
Cage is skidded off, due to being not easy to reload cage after in protective cover, skidding off, and the flexible constant velocity joint having
Heavier-weight, the workload for the cage that bigger exacerbation reloads.
Utility model content：
The purpose of this utility model is exactly in order to solve existing issue, and providing one kind prevents flexible constant velocity joint
Three ball pins skid off cage in carrying or installation process, avoid installation personnel and produce unnecessary workload, improve installation rate
Anti-dropout flexible constant velocity joint.
Technology solution of the present utility model is as follows：
A kind of flexible constant velocity joint of anti-dropout, including cage, the cage are provided with openend and blind end, institute
The blind end of cage is stated integrally formed with gearbox connecting shaft, the wheel hub of the interior extension of the oriented cage of openend sleeve of the cage
Connecting shaft, one end inside cage of the wheel hub connecting shaft are fixed with three ball pins, are rotated in three ball pin and be provided with three
Individual ball, hollow catch is fixed with the openend side of the cage, Circle-Array shows three and ball on the catch
The notch that cross section is engaged, the length L1 of the notch are more than 0.11~0.14mm of ball diameter.
Preferably, being additionally provided with protective cover between the cage and the wheel hub connecting shaft, it is fixed with the protective cover
Clip.
Preferably, the outline of the catch and the outline of the cage match.
Preferably, shaping positions annular groove, the protective cover in the wheel hub connecting shaft and the cage cylindrical wall
The ring rib being engaged with positioning annular groove is formed on inwall.
Preferably, the clip is two, one of them is fixed on outside cage, and another is fixed on wheel hub connecting shaft
On outside protective cover.
The beneficial effects of the utility model are：Prevent flexible constant velocity joint three balls in carrying or installation process
Pin skids off cage, avoids installation personnel and produces unnecessary workload, improves installation rate.

Embodiment：
As Figure 1-3, the flexible constant velocity joint of anti-dropout, including cage 1, the cage 1 are provided with openend
And blind end, the blind end of the cage 1 is integrally formed with gearbox connecting shaft 2, the openend sleeve oriented sphere of the cage 1
The wheel hub connecting shaft 3 of extension in cage 1, one end inside cage 1 of the wheel hub connecting shaft 3 is fixed with three ball pins 4, described
Rotated in three ball pins 4 and be provided with three balls 5, hollow catch 6, the catch 6 are fixed with the openend side of the cage 1
Upper Circle-Array shows three notches 7 being engaged with the cross section of ball 5, and the length L1 of the notch 7 is more than the diameter 0.11 of ball 5
~0.14mm.
Specifically, protective cover 8 is additionally provided between the cage 1 and the wheel hub connecting shaft 3, is fixed on the protective cover 8
There is clip 9, this setting can prevent the debris of outside from entering cage 1, influence the normal rotation of wheel hub connecting shaft 3.
Specifically, the outline of the catch 6 and the outline of the cage 1 match, on the one hand this, which is set, adds
Aesthetic property, it on the other hand it also avoid producing interference with protective cover 8.
Specifically, positioning annular groove 10, the protection are molded in the wheel hub connecting shaft 3 and the cylindrical wall of the cage 1
The ring rib 11 for forming on 8 inwalls and being engaged with positioning annular groove 10 is covered, using positioning annular groove 10 and ring in this setting
Shape raised line 11 coordinates so that protective cover 8 positions more convenient accurate with cage 1.
Specifically, the clip 9 is two, and one of them is fixed on outside cage 1, and another is fixed on wheel hub connecting shaft
On protective cover 8 outside 3, this sets the firmness for improving protective cover 8.
Operation principle：Wheel hub connecting shaft 3 is relative can be slided with cage 1 along the axial line of wheel hub connecting shaft 3, when cage 1
When openend is without catch 6, cage 1 is easily slid out in carrying or installation process, once cage 1 is skidded off, due to the screening of protective cover 8
Gear, can not accurately by wheel hub connecting shaft 3 again insertable into cage 1, it is necessary to trial repeatedly could be again insertable into, and some
The weight of the wheel hub connecting shaft 3 of oversize vehicle is larger, and installation personnel can not be set by hand by it again insertable into taking time and effort very much
After catch 6, because the length L1 of notch 7 thereon is more than the 0.11~0.14mm of diameter of ball 5, so three ball pins 4 can not skid off ball
Cage 1, nor the angle of the deflection of wheel hub connecting shaft 3 can be influenceed.
Preferred embodiment of the present utility model is the foregoing is only, those of ordinary skill in the art are not making creativeness
The every other embodiment obtained under the premise of work, it should all belong to the scope of the utility model protection.
