Abstract: A driver pulley system for use in a torque converter comprises a torque transmission device. The torque transmission device is used to transmit torque between components of the driver pulley system.

Abstract: A belt tensioner for use with a torque converter to adjust the overall speed of a vehicle is disclosed. The belt tensioner includes motion transmitting fixed unit configured to be fixed to a vehicle output shaft for movement therewith and a belt tensioning movable unit configured for movement relative to the fixed unit. The fixed unit includes a cam and the movable unit includes a cam follower and a rotation limiter. The cam follower is configured to follow the cam to tension a belt located between flanges of the fixed and movable units. The rotation limiter is configured to engage the cam to limit relative rotation between the cam and the cam follower away from one another.

Abstract: A driven pulley system for use in a torque converter of a vehicle is disclosed. The driven pulley system includes a motion-transmitting fixed unit and a belt-tensioning movable unit. The fixed unit is arranged to be fixed to a rotatable output shaft of the vehicle for rotation therewith to transmit motion between the output shaft and a belt included in the torque converter and includes a fixed flange and a cam. The belt-tensioning movable unit is arranged for movement relative to the fixed unit and includes a movable flange and a cam follower. The fixed flange and the movable flange cooperate to receive the belt therebetween for engagement therewith. The movable flange includes a rotation limiter arranged to engage the cam to limit rotation of the cam relative to the cam follower in a second direction opposite to the first direction.

Abstract: A limited slip differential for driving axles of a vehicle wherein a rotating differential connects the axles to an engine and wherein a torque override assembly is provided to limit relative rotation between the two axles by connecting a spring biased frictional disk drive between the rotational differential and one axle by bolting the input drive to the disks to the rotational differential and keying the output drive of the disks to one of the axles. Varying limits of the torque override is obtained by any one of: the number of disks used, the material of the disks, and the strength of the spring.

Abstract: According to the present invention, a bearing assembly includes a rotatable hub and a porous bearing surrounding the hub, a sprocket surrounding the bearing, and means for rotating the hub relative to the bearing. The porous bearing includes “lubricant channels” containing a lubricant and having inlet openings facing toward the sprocket and outlet openings facing toward the rotatable hub so that lubricant in the lubricant channels can exit through the outlet openings to lubricate the mating surfaces of the bearing and the rotatable hub. The porous bearing is permeable to fluids and thus capable of being penetrated by lubricants and greases and thus due to its porous character includes lubricant channels that function to conduct lubricants and greases from an outer surface of the porous bearing to an inner surface of the porous bearing through lubricant channels or pores formed in the porous bearing.
