No. 7-12 [0004] SUMMARY OF THE INVENTION This type of joint smell
So far, the outer surface of the cage has been
Only a spherical surface for providing a support on the joint member
The inner surface of the cage supports the inner member on one side in the axial direction.
It has been proposed to form an inward spherical surface. In order to fix the cage in the axial direction, the outer joint is used.
The claw member has separate stop means acting axially on the cage.
Have. In the annular shape, the stopping means is provided with an outer joint.
If they are fixed to the open ends of the hook members, they are joints
Can be limited. Stop means for outer joint member
If it is fixed to the connection end of the outer joint after assembly
Providing a separate joint base that must be connected to the member
There is a need. [0006] It is an object of the present invention to provide a system which is substantially axially general.
Inner joint member and outer joint when aligned
Opposite track joints with which members can be assembled
To provide. [0007] The above object has the following features.
In other words, the outer joint member is the inner joint portion.
A first opening towards the connection end of the material and said outer joint
Including a second opening toward a connection end of the member;
On the inside, the outer joint member is connected to the ball cage.
Axially with respect to said outer joint member during the assembly of the hook
Forming an axially movable surface movable in the direction;
Wherein the outer joint member is for an outer surface of the ball cage.
Forming a first stop and a guide surface, the first stop and the plan
An inner surface facing the second axial direction;
The holding element inserted into the hook member is outside the ball cage.
Forming a second stop and guide surface for the surface,
And a guide surface facing the first axial direction;
On the inside, the ball cage is the spherical shape of the inner joint member
The outer surface is axially movable during assembly of the fitting
Forming a guide surface, the guide surface for the inner joint member;
It changes to the third stop and guideway, and the third stop and guide
And a guide surface facing the second axial direction;
In order to assemble a joint, the holding element is
A connection end of the outer joint member released from the hook member
Toward the second axis and the joint is
When assembled, the holding element in a play-free way
In order to fix the ball cage in the axial direction,
The first axial direction toward the connection end of the inner joint member
And the retaining element is attached to the inner joint member.
Stop and axial support on the outer joint member
Be provided with a fitting of the type mentioned first.
And is achieved by: For assembly, the outer joint member
The coaxially aligned cage is connected to the outer joint member.
It cannot be moved axially within a predetermined area with respect to the connecting end.
I have to. After ball is attached, inner joint
The hand member is slid from the connection end of the outer joint member and
Introduced into the cage, the axial direction of the cage in the outer joint member
The travel path of the
The ball is guided so that the hook member is guided through the ball.
Dimensioned to allow entry into the deepest area of the outer orbit
Attached. Subsequently, the inner joint member is
The member is moved in the opposite direction toward the connection end. Axial direction
Is fixed by inserting a holding element from the connection end of the outer joint member.
It is done by entering. The outer joint member has openings at both ends.
To form a continuous interior. Cage and inner joint members
Manufactured to be integral with the outer joint member
Connection of inner joint member by first stop and guide surface
Supported towards the edge, its advantage is the fitting journal
Joint movement of the outer joint member at the joint end
Is not limited by the holding factor. According to an advantageous embodiment, the outer joint
The axial movement surface of the member is axially from the first stop and guide surface
At least to the deepest point of the second outer orbit.
Is proposed. The moving surface in the axial direction is preferably
A cage in a play-free manner throughout the directional movement
It is cylindrical inside so that it can be inside. [0011] The holding element is preferably a tubular sleeve.
Of a sheet metal cover with a flat base attached to it
Provided in the form. According to yet another embodiment, the holding
The element is moved axially into the base opening of the outer joint member
The second opening is adapted to insert a fixing ring.
It may be proposed to include an annular groove. In principle, the inner joint member and the retaining element
A second opening of the outer joint member from the connection end of the outer joint member
Can be inserted into the outer joint member only through
On the other hand, the cage is disengaged from the connection for the inner joint
To the outer joint member only through the first opening of the outer joint member
Can be introduced. First, cage, then bo
And then the inner joint member must be attached
No. According to a first possibility, the inner joint member
It is suggested that the spherical outer surface be manufactured to be integral with it.
Is proposed. According to a second possibility, the inner joint member is a ball
May include a separate plug forming the central portion of the outer surface
Suggested. In a particularly convenient way,
Type of fitting increases the strength of the connection and the number of parts
The outer joint member and the inner joint part
One-piece, allowing substantially axial assembly
Including inner joint members with joint journals
Thus, the coupling need not be articulated. As a result, the perimeter of the cage window is
Can be limited to the dimensions required for the connecting angle of
As a result, the strength of the cage is also increased
You. The outer surface of the ball cage is preferably spherical.
According to yet another particularly advantageous embodiment, the bare
The bearing is slid directly on the outer joint member and the bearing is
The outer joint part is slid from the connection end of the inner joint member.
Double row of bases that are axially fixed by
Alling is suggested. In this method, the joint and the wheel hub
Are integrated with the bearing and are
The number of articles is therefore reduced. In the middle of a rush joint
The length of the axle can be increased. Achieve favorable supportive movements
In order for the two rows of balls in the bearing to preferably
When the fittings are aligned, pass through the center of the ball
Are positioned on both sides of the extending plane. The outer joint member is pivoted toward its connection end.
The cage is temporarily
Includes an interior that can go deeper into the
After the inner joint member is installed, the cage and inner joint
The hand member moves in the direction toward the connection end of the inner joint member.
And can be fixed axially by holding elements
The feature is that it. According to yet another advantageous embodiment,
Whether the first pair of tracks is arranged radially opposite to the first pair of tracks
Two track pairs are arranged radially opposite to the second track pair
It is suggested that In particular, the first track pair and the second track
The pairs of roads are arranged alternately across the circumference
Is proposed. Preferably, eight uniformly distributed around the periphery
A joint having a pair of orbits is proposed. Identified hand
Steps are offset from zero radially on those balls
Consequent control applied by opposing orbit pairs
Achieve your power. In this way, cage control is improved
Is done. A preferred embodiment of the present invention is shown in the following drawings.
