Description

[0001] TRIPOD HOUSING OF CONSTANT VELOCITY JOINT FOR VEHICLE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tripod housing of a constant-velocity joint for a vehicle. More particularly, the present invention relates to a tripod housing for a vehicle, The present invention relates to a tripod housing of a constant-velocity joint for a vehicle.

Generally, a joint used in a vehicle is for transmitting rotational power (torque) to a rotation shaft having a different angle of rotation axis. In the case of a propulsion shaft having a small power transmission angle, a hook joint, a flexible joint, or the like is used. In the case of a drive shaft of a large front wheel drive vehicle, a constant velocity joint is used.

Since the constant velocity joint can transmit power smoothly at a constant speed even when the angle of intersection between the drive shaft and the driven shaft is large, it is mainly used for the axle shaft of the independent suspension type front wheel drive vehicle, and the engine side (inboard side) Type joint, and the tire side (outboard side) around the shaft is made of a ball type joint.

As shown in FIGS. 1 and 2, the tripod type constant velocity joint includes a triad housing 10 integrally formed therein, three tripods 21 provided in the tripod housing 10, A needle bearing 30 provided on the outer circumferential surface of the trunnion 21, a ring-shaped ball 40 provided on the outer circumferential surface of the needle bearing 30, And a boot 60 coupled to the other end of the shaft 50 coupled to the center of the spider 20.

The tripod housing 10 includes a cup portion 11 and a stem portion 12. The stem portion 12 is connected to the transmission to transmit the rotational force of the engine to the cup portion 11 And the cup portion 11 is engaged with the spider 20 having the ball bearing 30 and the ball 40 coupled to transmit the rotational force to the shaft 50 and the axial movement.

In the meantime, the stem 12 of the tripod housing 10, which is connected to the transmission, must be changed to a different type. In this case, the conventional tripod housing 10 Has a disadvantage in that the cup portion 11 and the stem portion 12 are integrated so that the entirety of the tripod housing 10 must be changed when the engine specifications are changed, .

It should be understood that the foregoing description of the background art is merely for the purpose of promoting an understanding of the background of the present invention and is not to be construed as an admission that the prior art is known to those skilled in the art.

3 is an exploded perspective view of a tripod housing according to the present invention,
Fig. 4 is an assembled state view of Fig. 3; Fig.
5 is a cross-sectional view of Fig.

Hereinafter, a tripod housing of a constant-velocity joint for a vehicle according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings, wherein like parts are denoted by like reference numerals.

3 to 5, a tripod housing of a constant-velocity joint for a vehicle according to the present invention includes a plate portion 111 formed on one side thereof and an inner space 112 formed on the other side thereof, A housing cup (110) having a peripheral portion (113); A housing stem 120 assembled to the plate portion 111 to transmit rotational power to the housing cup 110; And a housing shaft 130 having one end connected to the housing cup 110 after passing through the housing stem 120 and the other end coupled to the transmission 200 so as to transmit power.

An assembly of the spider 20, the needle bearing 30 and the ball 40 described above with reference to FIGS. 1 and 2 is installed in the inner space 112 of the housing cup 110.

Accordingly, when the power of the engine is transmitted to the housing shaft 130 through the transmission 200 to rotate the housing shaft 130, the rotational force of the housing shaft 130 is transmitted through the housing stem 120 to the housing cup 130 110 and the rotational force of the housing cup 110 is transmitted to the shaft 50 (see FIG. 1) coupled with the spider 20 through the assembly of the spider 20, the needle bearing 30 and the ball 40 do.

According to the present invention, a tapped hole 114 for coupling with the housing shaft 130 is formed at the center of the plate portion 111, and a coupling with the tapped hole 114 is formed at one end of the housing shaft 130 So that one end of the housing shaft 130 is threadably coupled to the plate portion 111 so as to be detachable.

The rotation direction in which the housing shaft 130 rotates when the screw portion 131 is assembled into the tapped hole 114 and the rotation direction in which the housing shaft 130 rotates due to the power of the engine are the same, When the shaft 130 transmits the rotational force, the housing shaft 130 is not loosened from the housing cup 110 but assembled more firmly.

A spline 132 coupled to the transmission 200 is formed at the other end of the housing shaft 130 so as to be rotatable by the power of the engine transmitted through the transmission 200. The spline 132 is connected to the transmission 200 ) With the differential assembly that constitutes the spline.

The housing stem 120 may include a flange portion 121 to which a plurality of portions are inserted into and coupled to the plate portion 111 so as to transmit rotational power to the housing cup 110 while being in contact with the plate portion 111; And a shaft portion 122 protruding in one direction from the center of the flange portion 121 and supporting a housing shaft 130 through which the housing shaft 130 penetrates.

A shaft hole 123 through which the housing shaft 130 passes is formed in the shaft portion 122 and the shaft hole 123 is formed to penetrate the center of the flange portion 121.

At least two coupling holes 115 are formed in the periphery of the tapped hole 114 in the plate portion 111 and coupling projections 124 are formed in the flange portion 121, Is formed so as to protrude to one side.

The coupling protrusion 124 assembled to the coupling hole 115 when the housing shaft 130 is firmly coupled to the shaft portion 122 serves to transmit the rotational force to the housing cup 110.

The coupling protrusions 124 are formed in the same number as the coupling holes 115. The plurality of coupling protrusions 124 can prevent the rotational force transmitted to the housing cup 110 from being transmitted in an eccentric state It is preferable that they are formed so as to be equally spaced along the circumferential direction about the shaft portion 122.

If the plurality of coupling protrusions 124 are not disposed at regular intervals along the circumferential direction around the shaft portion 122, when the rotational force is transmitted to the housing cup 110, The housing cup 110 is eccentrically rotated without being rotated in the garden state. As a result, when the eccentric rotation is performed as described above, the power transmitted to the wheel becomes unstable as a result , And furthermore, damage and breakage of the power transmission parts.

A locking protrusion 125 is formed on the inner circumferential surface of the shaft portion 122 and a locking protrusion 125 is formed on the outer circumferential surface of the housing shaft 130 when one end of the housing shaft 130 is coupled to the plate portion 111. [ When the one end of the housing shaft 130 is engaged with the plate portion 111 by the screw portion 131 and the tapped hole 114, the latching protrusion 133 is caught The flange portion 121 of the housing stem 120 is tightly coupled to the plate portion 111 of the housing cup 110 to transmit smooth rotation force.

As described above, the tripod housing of the constant-velocity joint for vehicle according to the present invention is configured such that the housing cup 110, the housing stem 120, and the housing shaft 130 are assembled so as to be detachable from each other, It is possible to separate only the housing shaft 130 or to separate the housing stem 120 and the housing shaft 130 from the housing cup 110 and to replace the housing stem 130 with a new one according to the changed engine specifications, The housing stem 110 or the housing stem 120 or the housing cup 110 can be commonly used irrespective of the engine specifications so that the management of the product can be facilitated and the cost can be greatly reduced .

While the present invention has been particularly shown and described with reference to specific embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the following claims It will be apparent to those of ordinary skill in the art.
