ABSTRACT:
A universal joint includes a journal cross having cross arms and yokes and spline shafts. The universal joint according to the invention comprises oil controllers, each in the form of a cylindrical cup made of a porous plastic material arranged in an oil reservoir in an end of the cross arm and communicating with an oil supply aperture of the journal cross. The controllers control the supply of amounts of grease to the journal cross arm ends resulting from centrifugal force, filter foreign substances such as metal particles so as to prevent abrasion of lubricated parts, and prevent grease from falling down under influence of gravity to restrain it as much as possible when the universal joint is stopped, thereby enabling the lubrication to perform smoothly when the universal joint is restarted.
