Embodiment Construction

[0022] The technical solutions of the present invention will be further specifically described below in conjunction with the accompanying drawings and specific embodiments.

[0023] combine Figure 1~3 , an automobile leaf spring bushing of the present invention, comprising an inner sleeve 1, an outer sleeve 2, a rubber filling layer 4 and a retaining ring 5, wherein the outer surface of the inner sleeve 1 is an outwardly protruding arc on the axial section of the bushing shape, the inner surface of the outer sleeve 2 is an arc protruding inward on the axial section of the bush, such a special structure restricts the movement of the filling rubber layer 4 between the inner sleeve 1 and the outer sleeve 2 along the axial direction of the bush, It not only increases the axial strength of the bushing, but also increases the radial strength of the bushing; there is a high damping alloy layer 3 between the inner sleeve 1 and the outer sleeve 2, which is a copper-zinc-aluminum alloy...

Abstract

The invention discloses an automobile leaf spring bushing and belongs to automobile suspension elastic elements. The bushing comprising an inner sleeve, an outer sleeve, filling rubber layers and retaining rings. The outer surface of the inner sleeve is in an arc shape protruded outwardly on the axial section of a bushing body, the inner surface of the outer sleeve is in an arc shape protruded inwardly on the axial section of the bushing body, a high damping alloy layer is arranged between the inner sleeve and the outer sleeve, and the filling rubber layers fill between the inner sleeve and the high damping alloy layer and between the outer sleeve and the high damping alloy layer; the inner sleeve is in a hollow cylindrical structure with two ends with steps, the diameters of two ends are smaller than the diameter of the middle of the inner sleeve, and two ends of the inner sleeve are provided with the retaining rings respectively through the steps of the inner sleeve. Owing to the unique shapes of the inner sleeve and outer sleeve, the radial strength of the leaf spring bushing is increased; the high damping alloy layer is arranged between the inner sleeve and the outer sleeve, the axial strength of the filling rubber layers is increased, and the fine damping performance is provided.

Description

technical field [0001] The invention relates to an automobile suspension elastic element, in particular to an automobile leaf spring bushing. Background technique [0002] Automobile leaf spring is the most traditional elastic element in automobile suspension system. It is widely used because of its good reliability, simple structure, short manufacturing process, low cost and greatly simplified structure. Automobile leaf springs are generally composed of several pieces of alloy spring steel with unequal lengths to form a group of similar-strength spring beams. [0003] The leaf spring bushing is a vulnerable part of the truck. It is installed in the leaf spring bracket assembly and the leaf spring coil ear to play the role of cushioning, shock absorption and force transmission, and has a great impact on driving comfort, stability and safety. And the convenience of maintenance and replacement plays an important role. The current market is used for the leaf spring bushing of...
