Novel transmission shaft support structure

Abstract

The invention provides a novel transmission shaft support structure. The novel transmissions shaft support structure comprises a rubber main spring, a rubber main spring inner metal piece, a rubber main spring outer metal piece and a standard bearing. The rubber main spring is mounted between the rubber main spring inner metal piece and the rubber main spring outer metal piece. The rubber main spring has a circular arc hollow inside. The rubber main spring inner metal piece is located at the inner ring of the rubber main spring, and the rubber main spring outer metal piece is located at the outer ring of the rubber main spring. The standard bearing is mounted on the rubber main spring. The novel transmission shaft support structure has the beneficial effects that product stiffness performance meets the whole vehicle NVH requirements; the reliability of the product is guaranteed, and the durability requirement of customers is met; the sealing performance of the product is improved, and the service life of the bearing is prolonged; the installation error of the yaw direction of a transmission shaft can be compensated for; by optimizing the structure of the inner metal piece, the qualification rate of the rubber main spring is increased; the problem of backlog of foreign liquids is solved; and the risk of falling off of parts of the product is reduced.

Description

technical field [0001] The invention relates to the field of automobile transmission shafts, in particular to a novel transmission shaft support structure. Background technique [0002] Current state of the art: [0003] As an important part of the automobile transmission system, the intermediate support of the drive shaft is mainly used to absorb the vibration generated between the drive shafts during the driving of the car, improve the NVH performance of the vehicle, and make the drive shaft both axial and radial. Slight offset; this part is generally assembled on the frame beam and used to connect the drive shaft, which has been widely used in some commercial / passenger models. [0004] Disadvantages / deficiencies of existing technologies: [0005] 1. The rigidity value of the product is high, the hardness of the rubber material is high, and the molding process is poor; [0006] 2. The durability of the product is poor. After working for a long time, the product is easil...

AI Technical Summary

Problems solved by technology

[0005] 1. The rigidity value of the product is high, the hardness of the rubber material is high, and the molding process is poor;

[0006] 2. The durability of the product is poor. After working for a long time, the product is easily damaged and broken due to the influence of high-frequency vibration and high temperature.
