The invention relates to a vehicle rubber damping bushing, and belongs to the technical field of vehicle damping bushings. The vehicle rubber damping bushing comprises a metal inner pipe, a rubber body and a plastic outer pipe; an annular projection structure is arranged on the outer surface of the middle part of the metal inner pipe; the projection structure extends into the rubber body; and close-up structures are arranged on the front and back end edges of the plastic outer pipe to the inner side. The vehicle rubber damping bushing is simple, compact and reasonable in structure; ports of the plastic outer pipe can shrink to effectively prevent falling of the rubber body from the plastic outer pipe; the projection structure in middle of the metal inner pipe can guarantee no falling of the vulcanized rubber body from the metal inner pipe; and through two semicircular plastic outer pipes, the machining cost is effectively reduced.
