Damping bushing for automobile transmission system and manufacturing method of damping bushing

Abstract

The invention discloses a damping bushing for an automobile transmission system. The damping bushing comprises an outer pipe and an inner pipe, the inner pipe is located in the outer pipe, the two ends of the inner pipe extend out of the outer pipe through extending sections, an outer convex ring is arranged in the middle of the inner pipe, the outer convex ring is matched with the inner side wall of the outer pipe, and the outer convex ring is fixedly connected with the outer pipe through screws. Rubber sleeves are arranged on the upper side and the lower side of the outer convex ring. The manufacturing method comprises the following steps that (1), the outer pipe and the inner pipe are manufactured; (2), drilling operation is carried out; (3), an end cover and the rubber sleeves are prepared; and (4), the damping bushing is assembled. According to the damping bushing for the automobile transmission system, the outer convex ring is adopted to achieve clamping connection between the inner pipe and the outer pipe, then the screws are combined to achieve fixation with the outer pipe, the installation firmness between the inner pipe and the outer pipe is effectively guaranteed, and the structural stability and firmness of the whole damping bushing are improved; and meanwhile, the outer convex ring is only arranged at the middle of the inner pipe, gaps exist between the upper sections and the lower sections of the inner pipe and the outer pipe, so that rubber sleeves are installed conveniently, and the damping and noise reduction effects of the damping bushing can be effectively guaranteed through the design of the rubber sleeves.

Description

technical field [0001] The invention belongs to the technical field of automobile transmission systems, and in particular relates to a damping bush for automobile transmission systems and a manufacturing method thereof. Background technique [0002] With the continuous improvement of people's economic income and the rapid development of the automobile manufacturing industry, automobiles have entered more and more ordinary families as a means of transportation. With the development of the automobile industry, people have higher and higher requirements for the comfort of the vehicle, including the comfort of shock absorption. As a key part of automobile shock absorption and noise reduction, the shock-absorbing bush plays a very important role. The key parts of the car will generate local vibration or noise due to the heavy load and the alternating load. Therefore, it is necessary to add shock-absorbing bushings to relieve the impact force and achieve the effect of shock absorp...
