Examples of the present application are given in the accompanying drawings. This application may, however, be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

It will be appreciated that spatially relative terms such as "under …," "under …," "below," "under …," "over …," "above," and the like may be used herein to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use and operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements or features described as "under" or "beneath" other elements would then be oriented "on" the other elements or features. Thus, the exemplary terms "under …" and "under …" may include both an upper and a lower orientation. Furthermore, the device may also include an additional orientation (e.g., rotated 90 degrees or other orientations) and the spatial descriptors used herein interpreted accordingly.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or be connected to the other element through intervening elements. In the following embodiments, "connected" is understood to mean "electrically connected", "communicatively connected", and the like, if the connected circuits, modules, units, and the like have electrical or data transferred therebetween.

As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms "comprises" and/or "comprising," and/or the like, specify the presence of stated features, integers, steps, operations, elements, components, or groups thereof, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, or groups thereof.

The penetrating type integral guide arm as shown in fig. 1-4 comprises a guide arm body 1, wherein a through hole 2 is formed in the guide arm body, and a shaft tube of an axle penetrates through the through hole 2 to be in clamping fit with the guide arm body. The axle tube of the axle, or the axle, passes through the through hole 2, the shape of the through hole 2 is matched with the section of the axle, and the effect of clamping and fixing can be realized after the axle tube is inserted.

The guide arm body 1 may be formed by splicing the upper and lower parts or splicing the front and rear parts, but most preferably, the guide arm body 1 is formed integrally. The guide arm body 1 formed integrally is of an integral structure, so that structural components fixed on an axle are reduced, materials are saved, weight is reduced, and cost is reduced. Also, because of the reduced structural members, the locations and probability of damage are reduced.

In order to improve the fixing effect of the guide arm body 1 and the axle, an extension plate 3 is connected to the side part of the guide arm body 1, and the extension plate 3 is attached to the axle tube of the axle. The extension plate 3 is also preferably integrally formed with the guide arm body 1. The extension plate 3 improves the contact area between the guide arm body 1 and the axle and reduces the contact surface pressure. Preferably, the extension plate 3 is continuously narrowed in the direction in which it protrudes, and the thickness is continuously thinned. The stress intensity of the part of the extension plate 3 far away from the guide arm body 1 is lower, so that the part of the extension plate, which is nearer to the guide arm body 1, is designed to be thicker, and the part of the extension plate, which is far away from the guide arm body 1, is designed to be thinner, so that the material can be saved, and the weight can be reduced.

The axle has a different rear cross-sectional shape, and in a conventional example, the axle has a square shape, i.e. the through hole 2 has a square shape, and the extension plate 3 has four sides corresponding to the four sides of the through hole 2 respectively.

Defining that one end of the guide arm body 1 connected with the air spring is a rear end 5, the other side is a front end 4, the front end 4 and the rear end 5 are limited by the through hole 2, the two sides of the front end 4 are provided with first grooves 6, and the two sides of the rear end 5 are provided with second grooves 7. The purpose of the first groove 6 and the second groove 7 is to reduce the weight of the guide arm body 1 to the maximum on the premise of meeting the stress requirement, and the available area of the second groove 7 is also reduced because the size of the rear end 5 is smaller than that of the front end 4, so that the second groove 7 can be communicated with the bottom of the rear end 5 for the maximum weight reduction.

The guide arm body 1 is thickened from two sides to the central axis, the section structure with the thick middle and the thin two sides accords with the stress simulation calculation, and also accords with the concept of maximizing weight reduction under the condition of meeting the stress requirement, and the guide arm body has higher structural strength and smaller risk.

Specifically, the end of the rear end 5 is connected with an ear plate 8, and the outer side of the ear plate 8 is connected with a reinforcing ring 9 of the matching hole. The ear plate 8 is used for fixing and connecting devices such as an air spring and the like, and the reinforcing ring 9 improves the structural strength of the connecting part.

The integral guide arm of this scheme runs through, has following characteristics:

the structure is simple: the guide arm body 1 is integrally formed, so that structural components fixed on an axle are reduced, materials and weight are saved, and cost is reduced.

The structural strength is high: the integrated guide arm body 1 is of an integral structure, so that damage positions and damage probability are reduced.

Good fixing effect: the extension plate 3 is connected to the guide arm body 1 lateral part, has increased the area of contact of guide arm body 1 and axletree, has reduced contact surface pressure.

High strength structure and weight reduction design: the arrangement of the first groove 6 and the second groove 7 realizes the maximum weight reduction of the guide arm body 1 on the premise of meeting the stress requirement; the two sides of the guide arm body 1 are thickened towards the central axis continuously, the section structure with the thick middle and the thin two sides accords with the stress simulation calculation, the structural strength is higher, and the risk is smaller.

In summary, the penetrating type integral guide arm has the advantages of simple structure, high strength, good fixing effect, material saving, weight saving, reinforced connection part and the like, and provides a high-performance, economical and practical guide arm scheme for the automobile manufacturing industry.

The foregoing description of the preferred embodiments of the utility model is not intended to limit the utility model to the precise form disclosed, and any such modifications, equivalents, and alternatives falling within the spirit and scope of the utility model are intended to be included within the scope of the utility model.
