Embodiment Construction

[0055]The technical solution of the present invention is described in detail below through the examples, and the following examples are only exemplary and can only be used to explain and illustrate the technical solution of the present invention, rather than being interpreted as a limitation to the technical solution of the present invention.

[0056] The application provides a leaf spring bushing structure, such as Figure 2 to Figure 12 As shown, it includes two outer bushes, two inner bushes and a shaft tube; the two outer bushes are set on the shaft tube, and the two inner bushes are respectively arranged on the outer bush and the shaft tube from both ends of the shaft tube between.

[0057] Simultaneously, the design of the leaf spring bushing structure also involves the leaf spring 4, pin shaft 5, leaf spring support 6 and the like.

[0058] The end of leaf spring 4 has leaf spring coil ear 41, and the width of leaf spring coil ear 41 is L1, and internal diameter is D4,...

Abstract

The invention relates to a plate spring bushing structure and a press fitting method thereof. The plate spring bushing structure comprises two outer bushings, two inner bushings and one axle tube; twoouter bushings are sleeved on the axle tube, and two inner bushings are arranged between the outer bushings and the axle tube respectively from two ends of the axle tube. Through the technical scheme, the assembly reliability of the plate spring bushings is improved and the performance of the plate spring bushings is ensured through the specific structure of the plate spring bushing and a matching press fitting device, and the installation precision and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of leaf springs, in particular to a leaf spring bushing structure and a pressing method thereof. Background technique [0002] In the guiding device of the suspension system (such as swing arm, rear axle, leaf spring, etc.), the hinge point connected with the body is more and more connected by rubber bushing. Rubber bushing has become an indispensable and important component in automobiles due to its good vibration isolation performance, elastic characteristics and attenuation characteristics. [0003] The suspension swing arm bush connects the suspension swing arm with the body (or frame, sub-frame). When the swing arm moves up and down, it acts as a buffer joint. When the suspension receives an impact, it acts At the same time, as a guide and force transmission element of the automobile suspension system, it transmits various forces on the wheels to the body while ensuring that the wheels move according t...
