Problems solved by technology

Before vulcanization, the inner ring 3 needs to be coated with adhesive. If the adhesive fails or the inner ring and rubber are unreliably bonded, the inner ring will be separated from the rubber layer, which will affect the vibration damping effect

Embodiment Construction

[0022] figure 2 , image 3 Among them, Embodiment 1 of the present invention includes a vibration damping body 1 and an inner ring 3 inside the vibration damping body 1 . The inner ring 3 is provided with a radial cavity 2 for filling rubber. The radial cavity 2 on the inner ring 3 of the present invention can ensure that the radial cavity 2 of the inner ring 3 is also filled with rubber after vulcanization, so that the rubber and the inner ring are combined into a firm whole. 4 is the positioning step.

[0023] Figure 4 Among them, a positioning step 4 is provided outside the damping body 1 .

[0024] Figure 5 Among them, 3 is the inner ring, and 2 is the radial cavity.

[0025] Figure 6 Among them, Embodiment 2 of the present invention includes the damping body 1 and the inner ring 3 inside the damping body 1 . The inner ring 3 is provided with a radial cavity 2 and an axial cavity 5 for filling rubber. The axial cavity 5 may or may not communicate with the radi...

Abstract

A damper for automobile transmission shafts comprises a damping body and an inner ring in the damping body; and the inner ring is provided with cavities in which rubber is filled. The damper ensures that the rubber is firmly integrated with the inner ring, so that the inner ring is prevented from being separated from the rubber layer due to the failure of adhesive or the unreliable adhesion of the rubber layer, and thereby the damper can effectively reduce the abnormal vibration of an automobile transmission shaft. The structure of the damper is simple and compact, integrated and standardized design and production are convenient, and the mounting space can be reduced. When the damper is produced, in the process of vulcanization, adhesive does not need to be applied, sand blasting is not needed, consequently, the production process is simplified, and the production efficiency is increased; meanwhile, since adhesive does not need to be used, the health of operators is prevented from being harmed, and environment pollution is prevented as well.

Description

technical field [0001] The invention relates to a vibration damping technology of an automobile transmission shaft. Background technique [0002] With the development of science and technology and manufacturing technology and the improvement of material living standards, people pay more and more attention to the comfort of car rides. Solving the NVH (noise, vibration and abnormal sound) problem is an important content to improve the ride comfort of cars. Among them, regulating the abnormal vibration of the vehicle transmission shaft is one of the key links to solve the vehicle NVH problem, and installing a shock absorber is the main means of regulating the abnormal vibration of the transmission shaft. [0003] The shock absorber is a mass spring damping system, its function is to regulate the abnormal vibration caused by the first-order bending mode of the transmission shaft, but it will not affect the balance, torsion and other characteristics of the transmission shaft. Pr...
