High-radial low-torsion multi-framework easy-to-control rubber bushing

Abstract

The invention provides a high-radial low-torsion multi-framework easy-to-control rubber bushing. The high-radial low-torsion multi-framework easy-to-control rubber bushing is composed of an inner framework (1), a middle framework (2), an outer framework (3), super-elastic rubber A (4) and super-elastic rubber B (5), wherein the heights of the inner framework (1), the middle framework (2) and the outer framework (3) are in a stair shape and gradually decreases towards the radial center line; and strip-shaped bosses (6) are arranged on the positions, with the same heights as the middle framework(2), of the outer wall of the left side and the outer wall of the right side of the inner framework (2), each strip-shaped boss (6) is connected to the outer wall of the inner framework (1), penetrates through the middle framework (2) and is close to but not in contact with the outer framework (3), and the height of each strip-shaped boss (6) is always equal to that of the middle framework (2). According to the rubber bushing, the combination of controllability and comfort is realized; and meanwhile, the super-elastic rubber is prevented from being cracked due to impact force in the running process, and the safety of the automobile is ensured.

Description

technical field [0001] The invention relates to the structural technical field of automobile rubber bushings, in particular to a multi-skeleton rubber bushing. Background technique [0002] At present, what is often encountered in the process of vehicle debugging and tuning is chassis tuning, which directly affects the driving control and comfort of the vehicle. Among them, the rubber hinge bushing of the chassis contributes a lot to the chassis tuning of the whole vehicle. A good bushing design directly affects the handling and comfort of the chassis. High control requires high stiffness to maintain stability and improve response speed, while comfort requires as low a stiffness as possible to buffer and absorb the excitation brought by the road surface. There is a contradiction between control and comfort. [0003] With the development of the automobile industry, consumers have higher and higher requirements for the comfort and handling of automobiles. At present, the app...

AI Technical Summary

Problems solved by technology

At present, the application of the soft connection of the existing design is not comprehensive. The common rubber bushing in the prior art is composed of an inner skeleton, an outer skeleton and rubber between the inner and outer skeletons, and the ratio of torsional stiffness to radial stiffness is not high. It is easy to control, which makes its comfort and handling difficult to adjust; if the comfort is high, the rubber bushing has low handling; if the handling is high, the rubber bushing is low in comfort
