Abstract
It is a technical object of the present invention to provide a tripod constant velocity joint which can prevent the ball from leaving the housing while minimizing cost and process. To this end, the tripod constant velocity joint of the present invention includes a housing in which the actuation mechanism is embedded, a boot provided at the end of the housing, and a stopper provided between the boot and the end of the housing and protruding toward the inside of the end of the housing. do.
Description
The present invention relates to a constant velocity joint for an automotive drive shaft.
In general, constant-velocity joints are used to transfer power to wheels mounted on a drive axle connected to a longitudinal decelerating device in a front wheel drive vehicle. At this time, the contact point between the driving shaft and the driven shaft is on the bisector of the intersecting angle, so that the power is transmitted at the constant speed.
The constant velocity joint includes a housing, an operating mechanism provided in the housing, and a boot connected to the housing and sealing the lubricant. In the case of a tripod constant velocity joint, the actuating mechanism generally comprises a spider on which three trunnions are protruded, a needle bearing on the outer circumferential surface of the trunnion, And a ring-shaped ball provided on the outer peripheral surface of the needle bearing.
In particular, the conventional tripod constant velocity joint has an extension portion formed by forming the end portion of the housing a little longer, a mounting groove formed on the inner circumferential surface of the extension portion, and a ring-shaped retainer fitted to the mounting groove to prevent the ball from being separated from the housing. retainer). Therefore, even if the drive shaft and the driven shaft are largely bent, the retainer blocks the phenomenon that the ball slips out of the housing.
However, in order to mount the retainer, the end of the housing needs to be long, and a separate mounting groove needs to be processed, thereby increasing the material cost and complicated manufacturing process. Furthermore, there is a staking process of plastically deforming the end of the housing as another way to prevent the ball from leaving the housing, which is not repairable in case of constant velocity joint failure.
The technical problem of the present invention is to provide a tripod constant velocity joint which can prevent the ball from leaving the housing while minimizing cost and process.
In order to achieve the above object, the tripod constant velocity joint according to an embodiment of the present invention, the tripod constant velocity joint, the housing in which the operating mechanism is built; A boot provided at an end of the housing; And a stopper provided between the boot and the end of the housing and protruding toward the inside of the end of the housing.
For example, the stopper may be integrally formed with the boot.
The boot may be made of chloroprene rubber (CR).
As another example, the stopper may have a bushing shape and may be provided separately from the boot.
The stopper may be fastened together when the housing and the boot are fastened by a clamp.
The boot may be made of a thermoplastic elastomer (TPE) material.
In addition, the tripod constant velocity joint according to the embodiment of the present invention may further include a reinforcing member provided in the stopper.
The reinforcing member may be processed while being inserted into the stopper.
The reinforcing member may be made of steel or plastic material.
The reinforcing member may have a disk or ring shape that surrounds an end of the housing.
In addition, the operating mechanism may include a ball, and a portion corresponding to the ball of the stopper may have a concave shape to be in surface contact with the ball.
As described above, the tripod constant velocity joint according to the embodiment of the present invention may have the following effects.
According to an embodiment of the present invention, since the stopper is integrally formed in the boot or the stopper is fastened together when the boot and the housing are fastened, it prevents the ball from leaving the housing while minimizing cost and process. Can be.
