FIELD: transport engineering; shells of ball joints of vehicle front suspension and steering gear. SUBSTANCE: spherical joint shell has inner and outer surfaces and truncated end face. projections are made on outer surfaces, and meridional grooves, on inner surface. Grooves communicate with through cuts. Center of outer spherical surface is displaced relative to Center of inner spherical surface in direction from truncated end face to provide stepless reduction of shell thickness. EFFECT: enhanced manufacturability, reliability and increased service life. 2 dwg
