Abstract
The invention relates to a tripod joint assembly, suited for the driveline of motor vehicles. It includes an outer joint part, rollers and an inner joint part which is connected to a shaft in a rotationally fast way, with an annular gap being formed between the shaft and the outer joint part, as well as a convoluted boot for sealing the annular gap. The outer joint part comprises a wall whose outer contour, in cross-section, deviates from the circular shape and which comprises a radially outwardly directed, circumferentially extending bead. The convoluted boot comprises an adapter ring and a convoluted portion connected to the adapter ring, with the adapter ring, on its radial inside, comprising an annular circumferential recess and, in its cross-section, being suitable for being fitted on to the outer joint part. When the adapter ring is fitted on to the outer joint part, the bead of the outer joint part engages the circumferential recess of the adapter ring in order to provide axial security.
