Rear drive transmission shaft supporting piece of integrated bidirectionally-vulcanized structure and machining method thereof

Abstract

The invention discloses a rear drive transmission shaft supporting piece of an integrated bidirectionally-vulcanized structure. The rear drive transmission shaft supporting piece of the integrated bidirectionally-vulcanized structure comprises a middle supporting installation support, a middle supporting bearing and middle supporting main springs. The two middle supporting main springs are in the same shape and are symmetrically arranged, each middle supporting main spring is of a rotary body structure, and the radial section of each middle supporting main spring is of a C-shaped structure. Each middle supporting main spring comprises an edge side and a bent side. The edge sides of the two middle supporting main springs are arranged oppositely. An inner side portion and an outer side portion which are both of an annular structure are arranged between the edge side and the bent side of each middle supporting main spring. Connecting portions used for connecting the inner side portions with the outer side portions are arranged on the bent sides of the middle supporting main springs. Radial protrusions of annular structures are arranged on the edge sides of the inner side portions towards the outer side portions. The rear drive transmission shaft supporting piece of the integrated bidirectionally-vulcanized structure can overcome the defects of the prior art and meet actual use requirements. The invention further discloses a machining method of the rear drive transmission shaft supporting piece of the integrated bidirectionally-vulcanized structure.

Description

technical field [0001] The invention relates to a rear drive transmission shaft support member with a bidirectional vulcanization integrated structure and a processing method thereof, belonging to the technical field of auto parts production and manufacturing. Background technique [0002] In the prior art, there are mainly two types of support structures for the rear drive transmission shaft: [0003] 1. Simple two-way assembly structure, and the main shortcomings are: the vulcanization production of the product is easy to crack, assembly requires manual work, large-scale mechanized production cannot be realized, the pull-out force of the bearing assembly is too small, and the product quality cannot be guaranteed. [0004] 2. The unidirectional vulcanization structure has the main disadvantages: the rubber protrusion cannot be designed due to the rigidity of the structure, the service life cannot be met during the axial fatigue movement of large displacement, the radial lim...

AI Technical Summary

Problems solved by technology

[0003] 1. Simple two-way assembly structure, and the main shortcomings are: product vulcanization production is easy to pull and crack, assembly requires manual work, large-scale mechanized production cannot be realized, bearing assembly pull-out force is too small, product quality cannot be guaranteed

[0004] 2. The unidirectional vulcanization structure has the main disadvantages: the rubber protrusion cannot be designed due to the rigidity of the structure, the service life cannot be met during the axial fatigue movement of large displacement, the radial limit of the product cannot realize integrated vulcanization, and the dynamic Balance position accuracy is not high

[0005] To sum up, the above-mentioned simple two-way assembly structure and one-way vulcanization structure are applied to the rear drive shaft support operation, and the NVH and production process control are difficult to meet the expected goals, so it is necessary to develop a new type of rear drive shaft support Structural parts to overcome the deficiencies in the prior art
