a moving prevention structure for a joint part of transfer and propellar shaft of four wheel drive vehicles

摘要

The present invention relates to a transfer and flow prevention structure of the propeller shaft connection of the four-wheel drive vehicle, the damper (100) for holding a rim portion of the companion flange (2) in connection to the body 200 of the connecting-up part is provided .; The damper 100 includes a rapid acceleration, rapid deceleration when the piston rod to be pushed upward by the movement of the slider (20, 20 '), and the sliders 20 and 20' to be pushed by the flow of the companion flange (2) (50,50 ') internal to the piston (51,51') of, and to the elastic supporting the slider and the piston rod a spring (60,60 ', 61,61') and said piston rod (50,50 ') and comprises a 'of the cylinder (13,13 hydraulic fluid to move into the cylinder on the opposite side through a capillary tube 14 to increase a) a piston rod (50,50).; Thus, the flow of the entire connecting portion is minimized, whereby the spring (60,60 ', 61,61'), the impact energy is absorbed by the fluid transport processes in the compression and cylinder (13,13 ') of the arrangement freedom of the surrounding parts is improved, and ride comfort is improved, there is an effect the service life of the connecting portion extends.
