Description
Technical field
The present invention relates to a kind of constant velocity universal joint drive spindle.
Background technology
Constant velocity cardan joint be the misaligned axis connection of two axis, and make two axles with the transmission of identical angular speed transport
Dynamic mechanism.It is the important component in car drivetrain system, it is to pass the power of engine from speed changer (differential mechanism) that it, which is acted on,
The driving wheel of automobile is delivered to, meets the requirement of car transmission shaft outer end corner；The power of engine steadily, is reliably passed to
Wheel；The bounce of car the inner suspension is compensated, driving car is run at high speed；Constant velocity cardan joint is the rotating speed of driving shaft and driven shaft
(angular speed) equal universal joint；On the automobile of front-wheel drive, its propons is equipped with constant velocity cardan joint transmission shaft, and (driving is simultaneous to be turned
To)；The power of front-wheel-drive cars, to be transferred directly to from the power assembly being made up of engine, speed changer and main reducing gear
Front-wheel.It is deflecting roller again and front-wheel is both driving wheel, the angle deflected during steering is very big, maximum up to more than 40 °；At this moment,
Traditional, deflection angle very little common universal drive shaft can not be used；Because Cardan joint can produce when deflection angle is big
The larger fluctuation of raw rotating speed and moment of torsion；Therefore it is necessary to using deflection angle is big, the uniform constant velocity cardan joint transmission shaft of angular speed
OK；The principle of constant velocity cardan joint is similar with the reason that conical gear engages, because the position of power transmission point is always at two axle clamp angles
Divide equally on face, hereby it is ensured that movement at the uniform velocity；The shortcomings that constant velocity cardan joint is that structure is more complicated, and manufacturing process is accurate, into
This is higher, therefore can't replace Cardan joint completely.The appearance of constant velocity cardan joint, promoted significantly front-wheel-drive cars and
The development of all-wheel drive vehicle.But during constant velocity cardan joint bearing torque load, each part can hit, now if each portion
Gap is bigger between part, and shock is heavier, can influence service life.
The content of the invention
Goal of the invention：The problem of existing for prior art, the invention provides a kind of positioning precision height, service life
Constant velocity universal joint drive spindle long, performance is good.
Technical scheme：A kind of constant velocity universal joint drive spindle, including central shaft and clutch can, the clutch can is interior to be provided with star
Set, is provided with fixed mount between the inner race outer wall and clutch can inwall；The fixed mount is provided with steel ball, the ball of steel ball movement
Road is located on clutch can inwall, and the alley is circular arc；The central shaft is connected inside clutch can with inner race；In described
Mandrel is provided with jump-ring slot with inner race junction, and the jump-ring slot is provided with bayonet unit；The central shaft is located on the outside of clutch can
Provided with pad.
Specifically, the steel ball has multiple.
Specifically, the fixed mount is arc.
Specifically, the length of the pad is more than the length of root diameter.
Specifically, the distance between the inner race outer wall and clutch can inwall are the length of a steel ball size.
Specifically, the central shaft Upper gasket thickness is 1-2cm.
Beneficial effect：Compared with prior art, the advantage of the invention is that：Bayonet unit is set on this jump-ring slot, it is fixed to make
Position precision is high, and gap is small between central shaft and inner race, and service life extends；Secondly, the pad on central shaft thickeies, usability
Can be more preferable；The alley of steel ball movement is circular arc so that precision is more preferable.

Alley 5 be located on the inwall of clutch can 2, the alley 5 is circular arc, and the distance between the outer wall of inner race 7 and the inwall of clutch can 2 are
The length of one diameter of steel ball 6；Central shaft 1 is connected through the inside of clutch can 2 with inner race 7；Central shaft 1 is connected with inner race 7
Place is provided with jump-ring slot 3, and the jump-ring slot 3 is provided with bayonet unit 4；Central shaft 1 is located at the outside of clutch can 2 and is provided with pad 8, pad 8
Length be more than the diameter of central shaft 1 length, the thickness of pad 8 is 1-2cm.
Fixing end universal joint full swing angle is 45 °, and packaged type universal joint full swing angle is 22 °.
During assembling, enough grease based on molybdenum disulfide lithium are injected in permanent universal joint and dust cover, in movable type ten thousand
Enough aviation lithium base greases are injected into section and dust cover；
