摘要： A tripod type constant velocity joint comprises a housing having three track grooves defined at trisected positions of the housing and extending in an axial direction, and a spider having three trunnions projectedly formed at trisected positions of the spider to be respectively inserted into the track grooves, each trunnion having at least two polygonal surfaces at each of two opposing sides subjecting to a load. Inner rollers each has an inner surface of a concavely curved contour for receiving a corresponding trunnion therein, and an outer is mounted to each inner roller with a plurality of needle rollers engaged there-between.

摘要： A tripod type constant velocity joint comprises a housing having three track grooves defined at trisected positions of the housing and extending in an axial direction, and a spider having three -trunnions projectedly formed at trisected positions of the spider to be respectively inserted into the track grooves, each trunnion having a generally oval or elliptical cross-sectional shape and including at least one independent contact surface at each of two opposing sides subjecting to a load. Inner rollers each has an inner surface of a concavely curved contour for receiving a corresponding trunnion therein, and an outer roller is mounted to each inner roller with a plurality of needle rollers engaged there-between.
