The invention discloses an automobile rubber bushing which comprises a bushing body, a core, a rubber part and an outer sleeve. A closing-up ring is fixed to one end of the bushing body, a connecting stud is fixed to the other end of the bushing body, the core is arranged at the central position inside the bushing body, the outer side of the core is wrapped with the rubber part, first annular flanges are equidistantly arranged on the core intermittently, the outer side of the rubber part is wrapped with the outer sleeve, second annular flanges are equidistantly arranged on the inner side wall of the outer sleeve intermittently, oil injection ports are evenly disposed at the top of the outer sleeve and communicate with a lubricating channel arranged in the outer sleeve, two annular grooves are intermittently formed in the outer side wall of the outer sleeve, and oil outlet holes are evenly formed in the inner sides of the annular grooves and communicate with the lubricating channel. By arranging the structure with the ends closed up, a phenomenon that the bushing body comes off can be avoided, and product quality and a damping effect are improved.
