Description

Technical Field

[0001] The utility model belongs to the technical field of automobile suspension accessories, and in particular relates to an automobile chassis and a bushing. Background Art

[0002] With the development of science and technology, the requirements for handling stability and NVH performance of automobiles at high speeds are becoming higher and higher. The elastic components used in automobile suspension mainly include bushings, shock absorber supports, suspension buffer blocks, suspension springs, etc. The main function of bushings is to isolate the vibration and impact caused by the road surface and attenuate the large amount of high-frequency vibration caused by the uneven road surface, which plays an important role in improving the smoothness of the car during driving.

[0003] However, when the car is driving, the tire will bounce up and down due to the excitation given by the ground, and the leaf spring will repeatedly undergo elastic deformation to absorb these excitations. The rear end ear assembly will rotate around the axis of the bushing. At this time, the ear assembly and the bushing will have relative movement, friction will produce abnormal noise, and affect driving comfort. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide an automobile chassis and a bushing to solve the technical problem of abnormal friction noise generated by the lifting ear assembly and the bushing during the driving process of the above-mentioned automobile.

[0005] In order to achieve the above object, the utility model provides the following technical solution: a bushing, comprising:

[0006] a bushing body, and;

[0007] The accommodating groove is arranged on the inner wall of the bushing body and is used for accommodating the wear-reducing material.

[0008] Furthermore, there are a plurality of accommodating grooves, and the accommodating grooves are distributed at intervals along the axial direction of the bushing body.

[0009] Furthermore, the accommodating groove is an annular groove.

[0010] Furthermore, the accommodating groove is a spiral groove.

[0011] Furthermore, the accommodating groove is a strip-shaped groove.

[0012] Furthermore, the cross-section of the accommodating groove is any one of a rectangle, a rhombus, a triangle, and a trapezoid.

[0013] Furthermore, the friction-reducing material is any one of lubricant, grease and lubricating oil.

[0014] Furthermore, the depth of the accommodating groove is 2-3 cm.

[0015] An automobile chassis comprises a pair of side plates arranged in parallel and at intervals, a lifting lug installed between the pair of side plates, and a bushing sleeved on the lifting lug, wherein the bushing is the bushing described above.

[0016] Furthermore, the end of the bushing is provided with a chamfer.

[0017] The beneficial effect of the utility model is that compared with the prior art, a bushing in the utility model is provided with a receiving groove on the bushing body, so that a friction-reducing material can be arranged in the receiving groove. In this way, when the bushing is in use, the friction-reducing material will flow out of the receiving groove, thereby reducing friction and eliminating abnormal noise. In addition, since the gap between the bushing and the external structural parts is small, the friction-reducing material is always in the gap, thereby avoiding the external loss of the friction-reducing material, and having a relatively long-term effect on solving the abnormal noise.

[0018] Other advantages, objectives and features of the utility model will be described in the following description and will be apparent to those skilled in the art to some extent, or those skilled in the art can be taught from the practice of the utility model. The objectives and other advantages of the utility model can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] like Figure 1 to Figure 2As shown, this embodiment proposes a bushing 1, including a bushing body 11, and a receiving groove 12 is provided on the inner wall of the bushing body 11, and the receiving groove 12 can be used to receive the anti-friction material. In this way, by arranging the anti-friction material in the receiving groove 12, when the bushing 1 is in use, the anti-friction material will flow out of the receiving groove 12, which plays a role in reducing friction and eliminating abnormal noise, thereby improving the driving comfort of the user. In addition, since the gap between the bushing 1 and the external structural parts is small, the anti-friction material is always in the gap, which avoids the loss of the anti-friction material to the outside, and can play a relatively long-term effect on solving the abnormal noise.

[0027] For further information, see Figure 1 and Figure 2 As shown, there are multiple accommodating grooves 12, and each accommodating groove 12 is spaced apart along the axial direction of the bushing body 11. Thus, by providing multiple accommodating grooves 12, friction-reducing materials can be added to the multiple accommodating grooves 12, thereby increasing the friction-reducing effect, effectively eliminating abnormal noise, and improving the driving comfort of users.

[0028] Preferably, in this embodiment, the number of the accommodating grooves 12 is 4-8, specifically, the number of the accommodating grooves 12 is 4, 5, 6, 7, 8, etc. Of course, according to actual conditions and specific needs, the number of the accommodating grooves 12 can also be set to other multiples, which is not limited here.

[0029] Preferably, the accommodating groove 12 is an annular groove. By setting it as an annular groove, on the one hand, it is easy to process and shape, and on the other hand, the accommodating space of the accommodating groove 12 is increased, so as to better eliminate the abnormal noise generated by the bushing 1 during use. Specifically, the annular groove can be a semi-annular groove or a full annular groove, which can be adjusted accordingly according to the situation. Preferably, in the present embodiment, the annular groove is a full annular groove, which is opened along the circumference of the bushing body. When the bushing 1 is in use, it can be completely filled in the gap between the bushing 1 and the external structural member, so as to better improve the friction reduction effect. Of course, in the present embodiment, the accommodating groove 12 can also be a spiral groove or a strip groove, or an accommodating groove of other shapes, which is not limited here.

[0030] Preferably, the cross section of the receiving groove 12 is any one of a rectangle, a rhombus, a triangle, and a trapezoid. Specifically, in the present embodiment, the cross section of the receiving groove 12 is a rectangle, and by setting it as a rectangle, the processing is convenient while ensuring that more anti-friction materials can be accommodated. Of course, in the present embodiment, according to actual conditions and specific needs, the cross section of the receiving groove 12 can also be set to other shapes, which is not limited here.

[0031] Preferably, the friction-reducing material is any one of lubricant, grease and lubricating oil.

[0032] For further information, see Figure 1 As shown, the depth of the receiving groove 12 is 2-3 cm. Specifically, the depth of the groove can be 2 cm, 2.2 cm, 2.4 cm, 2.6 cm, 2.8 cm, 2.9 cm, 3 cm, etc. Of course, in this embodiment, the depth of the receiving groove 12 can also be determined according to the on-site conditions, which will not be described here.

[0033] In the present application, a vehicle chassis is also provided, which includes a pair of side panels 2, which are distributed in parallel and at intervals, and a lifting ear 3 is provided between the pair of side panels 2, and a bushing 1 is provided on the lifting ear 3. Specifically, the bushing 1 is the bushing 1 described above, which will not be described in detail here.

[0034] Furthermore, the end of the bushing 1 is provided with a chamfer. By providing the chamfer, the installation and removal of the bushing 1 can be facilitated, and the assembly efficiency can be improved. Preferably, the chamfer is 45°-60°. By selecting this angle range, it can be adapted to commonly used tools for processing, thereby improving processing efficiency.

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the utility model.
