Zusammenfassung:The invention relates to an inner joint part (1) of a tripod constant velocity joint (2), comprising a hub (3), which has an axis of rotation (4), and three projections (5), which extend outward from the hub (3) in a radial direction (6) and have a transition region (48) adjoining the hub (3) and a bearing region (59), wherein the following applies: the spherical circumferential surface (9) of each projection (5) forms a first surface line (10) extending in the first plane (8), wherein an inner sphere (13) having an inner-sphere radius (19) is specified, which inner sphere contacts the opposite contact points (52) of the first surface line (10); the first surface line (10) of each projection (5) extends at least in first angle ranges (20) adjacent to the respective contact point (52) outside the inner sphere (13); there exists a second surface line (15) in a second plane (16); and the second surface line (15) touches the inner sphere (13) at touch points (60) only at the height (11) of the largest diameter (12) of the projection (5) and extends at least in second angle ranges (34) adjacent to the respective touch point (60) within the inner sphere (13). The invention further relates to a roller element (28) of a tripod constant velocity joint (2) having a convex inner circumferential surface (29), wherein the extension line (25) of the inner circumferential surface (29) forms an extension line radius (23), the magnitude of which is at a maximum in a central region, and the magnitude of the extension line radius (23) is less in an adjacent region (62). La presente invención se relaciona con una parte interior de junta (1) de una junta homocinética de trípode (2) comprendiendo un cubo (3) teniendo un eje de rotación (4) y tres muñones (5) que se proyectan del cubo (3) en una dirección (6) radial afuera y una región de transición (58) adyacente al cubo (3), así como una región de cojinete (59), valiendo lo siguiente: - la superficie circunferencial (9) esférica de cada muñón (5) forma una primera línea generatriz (10) que se extiende en un primer plano (8), estando definida una esfera interior (13) teniendo un radio (19) de esfera interior que contacta los puntos de contacto (52) opuestos de la primera línea generatriz (10); - la primera línea generatriz (lo) de cada muñón (5) se extiende en las primeras regiones de ángulo (20), adyacentes en cada caso el respectivo punto de contacto (52), afuera de la esfera interior (13); - hay una segunda línea generatriz
