Abstract
An invention relating to a constant velocity joint is disclosed. The disclosed constant-velocity joint includes an outer race member that is rotated by receiving power from the engine and has a track groove formed therein, a shaft member inserted into the outer race member, a spider member coupled to the shaft member and formed with trunnions, And a roller member which is enclosed in the track and is accommodated in the track groove and in which a lubricant is movably provided inward.
Description
TECHNICAL FIELD The present invention relates to a constant velocity joint, and more particularly, to a constant velocity joint capable of stably transmitting power by smoothly supplying lubricant to reduce lateral vibration of a vehicle.
Generally, a joint is for transmitting rotational power (torque) to a rotation shaft having different angles 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. A constant velocity joint is used.
Since the constant velocity joint can transmit power smoothly at constant speed even when the intersection angle of 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. The engine side (inboard side) Type joint, and the wheel side (outboard side) is composed of a fixed ball type joint around the shaft member.
Conventional constant velocity joints suffer from noise and power loss caused by frictional friction of the device due to low efficiency of lubricant transfer to the inside thereof, and cause wear and breakage of the device as the durability progresses, .
BACKGROUND ART [0002] The background art of the present invention is disclosed in Korean Patent Laid-Open Publication No. 10-2015-0000767 (published on May 20, 2015, entitled "Constant Velocity Joint").
It is an object of the present invention to provide a constant velocity joint capable of reducing the lateral vibration of the vehicle by reducing the axial force by improving the lubrication performance by guiding the movement of the lubricant.
A constant velocity joint according to the present invention comprises: an outer race member which is rotated by receiving power of an engine and in which a track groove is formed; A shaft member inserted into the outer race member; A spider member coupled to the shaft member and having a trunnion formed therein; And a roller member surrounding the trunnion and being accommodated in the track groove and having a lubricant movably inwardly.
In this embodiment, the roller member includes: an inner roller portion provided on an outer circumferential surface of the trunnion; An outer roller portion surrounding the inner roller portion so as to be spaced apart from the inner roller portion and received in the track groove; An intermediate roller portion interposed between the inner roller portion and the outer roller portion; And a retainer portion coupled to the outer roller portion to prevent the outer roller portion from being disengaged and having a lubricant supply hole formed therethrough so that a lubricant can be introduced and withdrawn from the intermediate roller portion .
In this embodiment, the outer roller portion includes: an outer roller body accommodated in the track groove; And a retainer seating groove portion formed on an inner circumferential surface of the outer roller body and into which the retainer portion is inserted.
In the present embodiment, the intermediate roller portion is a needle roller.
In the present embodiment, the retainer body includes a retainer body having an outer circumferential surface coupled to the outer roller portion and adapted to be engaged with the inner roller portion by movement, thereby preventing the outer roller portion from being disengaged, and the lubricant supply hole being formed through .
In this embodiment, the lubricant supply hole portions are arranged at regular intervals along the circumferential direction of the retainer body.
In the present embodiment, the retainer portion is provided with a pair of intermediate roller portions interposed therebetween.
The lubricant supply hole portion formed in the retainer portion at a distance from the shaft member as a reference in the pair of retainer portions in this embodiment is characterized in that the lubricant supply hole portion progresses toward the intermediate roller portion side and its inner diameter becomes narrow.
The constant velocity joint according to the present invention can smoothly supply the lubricant to the intermediate roller portion provided between the outer roller portion and the inner roller portion, thereby reducing the axial force, thereby reducing the lateral vibration of the vehicle and improving the durability of the device.
In addition, since the outer roller portion and the inner roller portion maintain the area in contact with the intermediate roller portion, and the lubrication performance is improved, damage or the like of the apparatus due to stress concentration can be prevented.
