Description

Shock absorber hub structure

This creation belongs to the technical field related to automobile accessories, especially a shock absorber hub structure.

As shown in Figure 6, the rear wheels of traditional truck suspension systems mostly use leaf spring assemblies 90, supplemented by hydraulic shock absorbers 80. The leaf spring assemblies 90 play important roles in the vehicle structure, such as connection, load bearing, vibration reduction, and stability enhancement.

Since the leaf spring assembly 90 has a relatively slow response to road vibration, it is used in conjunction with the hydraulic shock absorber 80 to achieve a complementary effect. However, during use, the hydraulic shock absorber 80 often bends and has uneven shock absorption and expansion, which is a problem that needs to be improved today.

As shown in the figure, the two ends of the hydraulic shock absorber 80 are connected to the frame 71 and the axle housing 72 respectively, providing the shock absorber 80 with the ability to absorb shock (stretch) along the extension direction. Among them, in the connection between the hydraulic shock absorber 80 and the axle housing 72, the pivot column 721 as the pivot point is perpendicular to the extension direction of the axle housing 72. Such a configuration of the hydraulic shock absorber 80 can easily cause the hydraulic shock absorber 80 to twist and be damaged.

Because the hydraulic shock absorber 80 is pivoted with the pivot post 721, it has an offset that pivots with the pivot post 721 as the axis and along the extension direction of the axle housing 72, but does not have such an offset along the extension direction of the frame 71 (the extension direction of the orthogonal axle housing 72).

The two ends of the axle housing 72 are respectively connected to the leaf spring assembly 90, and the displacement of the axle housing 72 in the upward and downward directions is eliminated by the deformation of the leaf spring assembly 90. Due to the deformation of the leaf spring assembly 90, the axle housing 72 will be linked to twist along the extension direction of the frame 71. Such a twisting direction synchronously links the pivoted hydraulic shock absorber 80 and also deviates in the extension direction of the frame 71. However, as can be seen from the above structure, the hydraulic shock absorber 80 does not have the activity to deviate along the extension direction of the frame 71 (the extension direction of the orthogonal axle housing 72) due to the assembly method. Such a deviation will inevitably cause the hydraulic shock absorber 80 to deform and be damaged.

Therefore, how to provide the displacement of the hydraulic shock absorber along the extension direction of the frame, and the hydraulic shock absorber assembly structure needs to be further improved.

In view of the problems and deficiencies of previous technologies, the main purpose of this invention is to provide a shock absorber pivot structure to solve the deficiencies of previous technologies through innovative structural design.

According to the above purpose of the invention, a shock absorber pivot seat structure is proposed to connect a shock absorber and an axle housing, wherein one end of the shock absorber is connected to a vehicle frame and the other end has a pivot hole. The two ends of the axle housing in the extension direction are respectively connected to a leaf spring assembly, and the axle housing further has at least one pivot column extending outward from the outer peripheral side of the axle housing. Its characteristic is that the pivot seat has a pivot part pivoted with the pivot column and a U-shaped part connected to the pivot part and pivoted to the shock absorber. By assembling the above components, the shock absorber is provided with multi-directional offset force, eliminating the damage to the shock absorber caused by the torsion of the axle housing.

Please refer to the relevant drawings below to further explain the embodiments of the shock absorber hub structure of the invention. The various objects in the embodiments are depicted according to the proportions, sizes, deformations or displacements applicable to the description, rather than the proportions of the actual components, which should be explained first. In addition, the same and symmetrically arranged components in the remaining embodiments are all represented by the same numbers. In addition, the directional terms such as "front, back, left, right, up, down, inside, outside" in the descriptions of the embodiments listed below are expressed according to the specified viewing direction and cannot be used as an interpretation of the limitations of the invention.

Please refer to Figures 1 to 5, which disclose a shock absorber hub structure for connecting a shock absorber 10 and an axle housing 72.

The shock absorber 10 is connected to the frame 71 (previous technology) at one end and has a pivot hole 11 at the other end. During implementation, the shock absorber 10 is selected from a hydraulic cylinder or a pneumatic cylinder.

The above-mentioned axle housing 72 (prior art) is connected to a leaf spring assembly 90 (prior art) at both ends along the extension direction of the axle housing 72, and the axle housing 72 has at least one pivot column 721 extending outward from the outer peripheral side of the axle housing 72; wherein the pivot column 721 is parallel to the extension direction of the frame 71 and is orthogonal to the extension direction of the axle housing 72.

In addition, the hinge seat 30 of the invention includes a hinge portion 31 and a U-shaped portion 32 disposed at two ends.

The above-mentioned hinge part 31 has a first axial hole 311, which is formed by passing through the hinge part 31. During implementation, the hinge part 31 is pivoted on the outer peripheral side of the hinge column 721 with the first axial hole 311.

The U-shaped portion 32 has a connecting arm 321, two vertical arms 322, and a second axial hole 323.

The connecting arm 321 horizontally connects the local edge of the outer peripheral side of the hinge part 31.

The vertical arms 322 are symmetrically arranged at the two ends of the connecting arm 321 in the extension direction.

The second axial hole 323 is formed by concentrically penetrating each vertical arm 322 and is arranged orthogonally to the first axial hole 311. In practice, the second axial hole 323 is concentric with the pivot hole 11 of the shock absorber 10, providing a pivot A to extend through and pivotally connect each vertical arm 322 and the shock absorber 10, so that the shock absorber 10 is arranged between each vertical arm 322.

Therefore, the above is an introduction to the various components and assembly methods of the shock absorber pivot seat structure of a preferred embodiment provided by this invention. The operating characteristics of the embodiment of this invention are introduced as follows.

The pivot A extends through the second axis hole 323 of the pivot seat 30 and the pivot hole 11 of the shock absorber 10, and is pivoted to the shock absorber 10 and the pivot seat 30, providing the displacement of the orthogonal axle housing 72 in the extension direction (displacement along the extension direction of the frame 71).

When the two ends of the axle housing 72 are deformed due to the movement of the leaf spring assembly 90 and are offset up and down and along the extension direction of the axle housing 72, they can form a pivot with the pivot column 721 through the first axial hole 311 of the pivot part 31. Provide the left and right direction offset of the shock absorber 10.

When the two ends of the axle housing 72 are deformed by the leaf spring assembly 90 and twisted, the axle housing 72 and the pivot seat 30 that are connected to the axle housing 72 twist along the extension direction of the frame 71. At this time, the shock absorber 10 can rotate with the pivot A as the axis through the pivot hole 11 and the second axis hole 323 of the pivot seat 30, providing the shock absorber 10 with a displacement perpendicular to the extension direction of the axle housing 72 (the extension direction of the frame 71), avoiding the movement with the axle housing 72, so as to overcome the problem of the shock absorber 10 being twisted and damaged.

As shown in FIG4 , a soft bushing 40 is sleeved between the pivot hole 11 of the shock absorber 10 and the pivot A. In practice, the soft bushing 40 is selected from rubber material, plastic material, or polyurethane (PU) material.

As shown in FIG4 , a hard sleeve 50 is sleeved between the soft sleeve 40 and the pivot A. In practice, the hard sleeve 50 is selected from metal material or Teflon material.

The above description is only the best implementation method of this creation, which is intended to clarify the characteristics of this creation, and is not used to limit the scope of the implementation of this creation. The equal changes made by ordinary technicians in this technical field based on this creation, as well as the changes familiar to technicians in this field, should still fall within the scope of this creation.
