Abstract
The drive shaft for an automobile according to an embodiment of the present invention includes a half shaft, an intermediate shaft coupled to one side of the half shaft and rotated by the power shaft to receive the power, a bearing fixed to the vehicle body, A fixed bracket for supporting the intermediate shaft, and a pressing member which is press-fitted into one side of the intermediate shaft and elastically deforms to press the intermediate shaft, and is disposed on one side of the bearing whose front surface is exposed, And a dust cover for closing the dust cover. According to the present invention, the recessed groove is formed in the intermediate shaft, and the dust cover is formed with the annular pressing portion that is seated in the seating groove through the elastic deformation, so that even when the external force or the rotational force is applied, So that foreign matter can be prevented from flowing into the bearing.
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drive shaft for an automobile, and more particularly, to a drive shaft for an automobile having an improved structure of a dust cover for blocking the inflow of foreign matter from the outside.
Generally, a drive shaft of an automobile is a device for transmitting a rotational driving force of a transmission to a driving wheel side, and includes an intermediate shaft disposed between a half shaft and a half shaft and a transmission for transmitting the power of the transmission to a half shaft, And a fixed portion for supporting an axial load of the intermediate shaft.
The fixing part is composed of a bracket fixed to the vehicle body, a bearing disposed inside the bracket and penetrating the intermediate shaft to the inside, and a dust cover coupled to the intermediate shaft and disposed in front of the bracket.
The dust cover is formed in a ring shape and includes a body portion coupled to the outside of the intermediate portion and an extension portion extending outwardly from the end portion of the body portion, and the front surface of the bracket is closed through an outwardly extending portion, It is possible to prevent foreign matter from being introduced into the bearing from the outside.
However, the conventional dust cover is merely inserted and fitted into the intermediate shaft, but is not completely fixed to the intermediate shaft, so that there is a problem that when the external force or the rotational force is applied, the dust cover is disengaged from the original assembly position.
Therefore, in order to prevent foreign matter from being introduced into the bearings and to prevent the dust cover from being separated from the bearing, additional parts for fixing the dust cover to the intermediate shaft or the vehicle have been required.
SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a drive shaft for an automobile, which is capable of blocking foreign matter introduced into a bearing, .
According to an aspect of the present invention, there is provided a drive shaft for a vehicle, including a half shaft, an intermediate shaft coupled to one side of the half shaft and rotated together with the half shaft, A fixed bracket having a bearing on its inner side to support the intermittent shaft and a fixed bracket that is press-fitted into one side of the intermittent shaft and elastically deformed to press the intermittent shaft, And a dust cover for closing the front surface of the bearing.
Wherein the dust cover has an annular pressing portion that penetrates the inside thereof and has an inner diameter smaller than the outer diameter of the intermediate shaft and is elastically deformed so as to flare outward when the pressing cover is inserted into the outer peripheral surface of the intermediate rod, And a cover portion extending to close the front surface of the bearing.
The pressing portion is provided with a locking protrusion protruding toward the intermediate shaft, and the intermitting shaft is formed with a locking groove on which the locking portion is seated.
The latching portion and the seating groove may be formed in a plurality of.
The pressing portion may have a plurality of mounting grooves recessed at a predetermined depth along the longitudinal direction from the end portion and spaced apart at regular intervals along the circumference of the pressing portion.
The latching portion may be rounded or chamfered.
The dust cover may be coated or coated.
According to the present invention, the recessed groove is formed in the intermediate shaft, and the dust cover is formed with the annular pressing portion that is seated in the seating groove through the elastic deformation, so that even when the external force or the rotational force is applied, So that foreign matter can be prevented from flowing into the bearing.
Further, since the dust cover is fixed to the intermediate shaft only by its own structure, it is possible to prevent the additional construction or process for fixing the dust cover from occurring, thereby reducing the cost.
