A plastic engine mount and its processing technology

Abstract

The invention discloses a plastic engine suspension. The plastic engine suspension comprises a suspension support, a rubber gasket, a gasket inner sleeve and a liner tube, wherein the suspension support is made of a high-strength polyamide material in an integral injection molding mode and comprises a cylindrical power installing part and a suspension fixing part, the rubber gasket is of a rotating body structure and coaxially arranged on the power installing part, the gasket inner sleeve is arranged in the axis of the rubber gasket, and the liner tube is arranged on the suspension fixing part. The plastic engine suspension is made of plastic instead of a metal material, the defects that a traditional engine suspension is large in weight, and the metal material is prone to corroding and has creep performance are overcome, and the thermal insulation and sound insulation effects of the engine suspension are improved, so that driving comfort of a vehicle is improved. The invention further discloses a machining technology of the plastic engine suspension, and production efficiency of the engine suspension is improved.

Description

technical field [0001] The invention relates to a plastic engine mount and a processing technology thereof, belonging to the technical field of automobile power train mounts. Background technique [0002] With the rapid development of the modern automobile industry and the increasing shortage of non-renewable resources, the requirements for lightweight and environmental protection of the vehicle are becoming increasingly stringent; High-end engine mounts are generally made of stamping, cast iron or cast aluminum. First of all, traditional engine mounts use more metal materials and are heavy, which is not conducive to the realization of vehicle weight reduction; secondly, the surface of metal materials used in traditional engine mounts needs to be treated with anti-corrosion treatment, which leads to engine mounts The processing cost is high; again, under the action of constant temperature and constant stress for a long time, metal has the characteristics of creep, which has...

Problems solved by technology

First of all, the traditional engine mounts use more metal materials and are heavy, which is not conducive to the realization of vehicle weight reduction; secondly, the surface of the metal materials used in traditional engine mounts needs to be treated with anti-corrosion, which leads to engine mounts The processing cost is high; again, under the action of constant temperature and constant stress for a long time, metal has the characteristics of creep, which has an adverse effect on the service life of traditional engine mounts; in addition, metal has high thermal conductivity and acoustic damping performance Poor, so traditional engine mounts cannot effectively insulate heat and sound, thereby affecting the comfort of the vehicle; finally, as described in the comparative examples in the specific implementation methods below, the processing technology of traditional engine mounts is relatively Complicated and difficult to process
