Abstract

The invention discloses a shock absorption ring used in an automobile transmission system, which is vulcanized by the adoption of a metal framework and rubber. A production technology is as follows: firstly, 80 portions to 120 portions of natural rubber NR, 35 portions to 50 portions of carbon black, 3 potions to 10 portions of high aromatic oil, 3 portions to 5 portions of an anti-aging agent, 1 portion to 2 portions of stearic acid, 4 portions to 6 portions of zinc oxide (indirect method), 1.8 portions to 2.8 portions of sulfur, 1.2 portions to 2.0 portions of an accelerant and 0.2 portion to 0.4 portion of an anti-scorching agent are mixed and kneaded into gross rubber by a Banbury mixer; and the qualified gross rubber after tests is milled and molded, and then put into a mould in a vulcanizer for vulcanization treatment. During the treatment process, the pressurization is carried out till 120 Kgf/cm2 to 160Kgf/cm2 and the temperature rises to 170 DEG C to 180 DEG C. And the treatment lasts for 6min to 8min and finally the obtained shock absorption ring is trimmed, verified and put in storage. The obtained shock absorption ring is characterized by high bonding strength, good elasticity, high damping, stable inherent frequency, good endurance quality and the like, and can improve the comfortability of the automobile and realize vibration absorption and noise reduction.

Description

Technical field: [0001] The invention mainly relates to a rubber part for a vehicle, in particular to a damping ring for a transmission system of a vehicle and a manufacturing process thereof. Background technique: [0002] In recent years, with the rapid development of the automobile industry, people have higher and higher requirements for the comfort of automobiles, including the requirements for the noise of automobiles. In China, the automobile transmission shaft assembly is mainly composed of the transmission shaft and the spline shaft welded at both ends and the universal joint fork. The vibration of the transmission shaft transmits the excitation energy to the body through the outer universal joint, wheel hub, and suspension. After the body panel is excited and resonated, the vibration energy is transmitted to the cavity, and the vehicle cavity emits rumbling low-frequency noise after being excited and resonated. In addition, the unevenness of the meshing rotation of...
