ABSTRACT:
A tripod joint has an outer joint part (1) with three uniformly circumferentially distributed axis-parallel recesses (2) forming circumferentially opposed tracks (4, 5), and an inner joint part (6) having a tripod-shaped cross-section with three circumferentially distributed arms (7) which extend into the recesses (2) of the outer joint part (1). Roller assemblies (8) are supported on the arms 7. Each roller assembly has at least one inner ring (12) and one outer roller (9) supported by the arms (7). The roller surface of the outer roller (9) rolls directly on the track (4, 5), with surfaces in each case being paired, such surface pairing enabling at least one radial sliding movement of at least part of a roller assembly (8) relative to the associated arm (7). A space (16) is formed between the roller assemblies (8) and the arms (7) for storing a first lubricant for the surface pairs enabling the radial sliding movement. The remaining joint interior or cavity (3) is filled with a second lubricant.
