Description

Technical Field

[0001] The utility model belongs to the field of automobile accessories, and more specifically, particularly relates to a mounting bracket under the front suspension of a commercial vehicle cab. Background Art

[0002] The front suspension lower mounting bracket is a connecting component connecting the vehicle cab and the frame. It is divided into a left mounting bracket and a right mounting bracket. Its function is to cooperate with the vehicle suspension shock absorber to reduce the vibration of the vehicle suspension system. At present, the component structure of the lower and middle mounting brackets in the front suspension system of the vehicle is relatively simple, and is only composed of a concave-shaped bent plate and a mounting through hole. In particular, the structural strength of the bent plate assembly of the lower mounting bracket is not high. Since the lower mounting bracket itself has to withstand the vibration of the frame, the lower mounting bracket is very prone to metal fatigue, causing structural bending or even structural fracture, resulting in failure of the vehicle cab connection support. It can be seen that the traditional front suspension lower mounting bracket has low structural strength and a short service life. Utility Model Content

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figure 1-Figure 6As shown, the utility model provides a commercial vehicle cab front suspension lower mounting bracket, comprising: a cushion block 2, a fixing bolt 5 and an upper support plate 7; the right end of the upper support plate 7 is welded to the side plate 4, and the front side of the side plate 4 is welded to the fixing foot plate 1 and the lower support plate 6; the fixing foot plate 1 is welded to the left and right sides of the support tube 8, and the upper side of the fixing foot plate 1 is welded to the lower side of the connecting plate 3; the upper side of the connecting plate 3 is provided with a through hole passing through from top to bottom near the front end, and the upper side of the connecting plate 3 is provided with two groups of connecting holes near the rear side; the lower side of the cushion block 2 is screwed with a fixing bolt 5.

[0022] When the utility model is used for mounting the lower front suspension bracket of a commercial vehicle cab, the two groups of connecting holes of the connecting plate 3 close to the rear side are butted at the mounting holes of the external frame, and the connecting plate 3 is fixedly mounted on the external frame by bolts, and the four groups of connecting holes of the side plate 4 are butt-mounted on the side of the frame, so that the lower bracket is firmly connected; then the bottom end of the external automobile suspension shock absorber is hinged between the two groups of fixed foot plates 1, and the stability characteristics of the triangular structure of the fixed foot plate 1 are utilized to strengthen the support structure strength of the fixed foot plate 1, so that the fixed foot plate 1 stably supports the external automobile suspension shock absorber, thereby improving the vehicle The shock absorption stability of the vehicle suspension shock absorber is improved, and the four groups of through holes of the side panel 4 are installed on the vehicle body with bolts. When the vehicle body vibrates, the through groove structure of the side panel 4 is used to enhance the flexibility and load bearing capacity of the side panel 4 itself, and prevent the side panel 4 from being deformed due to vibration. The side panel 4 cooperates with the lower support plate 6 and the upper support plate 7 to provide horizontal support at the L-bending part of the side panel 4, so that the lower support plate 6 and the upper support plate 7 support or pull the bent plate surface of the side panel 4, thereby improving the L-shaped folding plate structure strength of the side panel 4, preventing the side panel 4 from being repeatedly folded and deformed due to vibration force, causing the L-bending part to break, thereby improving the service life of the front suspension lower mounting bracket structure.

[0023] In the disclosed embodiment, the side panel 4 is an L-shaped folding plate structure. The right side surface of the folding plate structure of the side panel 4 is provided with four groups of through holes and a group of through groove structures which pass through the left and right sides. The through groove processing of the side panel 4 can improve the flexibility and load bearing capacity of the side panel 4 to avoid deformation or breakage caused by excessive force. The inner side surface of the bending part of the L-shaped folding plate structure of the side panel 4 is welded and connected with a lower support plate 6. The lower support plate 6 is used to strengthen the support of the L-shaped folding plate structure of the side panel 4 to prevent the side panel 4 from bending and deforming due to the longitudinal load.

[0024] In the disclosed embodiment, there are two groups of fixed foot plates 1, which are symmetrically distributed on the left and right. Each group of fixed foot plates 1 adopts a triangular flat plate structure. The fixed foot plates 1 are provided with circular through holes that pass through the left and right sides. The bottom end of the external automobile suspension shock absorber is hinged in the circular through hole of the fixed foot plates 1. The triangular flat plate structure of the fixed foot plates 1 utilizes the stability of the triangle to enhance the supporting structure strength of the fixed foot plates 1, thereby ensuring stable shock absorption of the automobile suspension shock absorber.

[0025] In the disclosed embodiment, the pad 2 is made of rubber material, and is arranged on the upper side of the connecting plate 3. The lower side of the pad 2 is provided with a bolt column, and the fixing bolt 5 is screwed on the bolt column of the pad 2. The bolt of the pad 2 is inserted into the through hole of the connecting plate 3.

[0026] In the disclosed embodiment, the upper support plate 7 is provided with a through groove structure which passes through from top to bottom. The through groove of the upper support plate 7 is utilized to enhance the flexibility and load bearing capacity of the upper support plate 7. If the side plate 4 is slightly bent and deformed by the longitudinal load, causing the left end of the upper support plate 7 to contact the fixed foot plate 1 on the right side, the upper support plate 7 cooperates with the fixed foot plate 1 to support the side plate 4, thereby preventing the side plate 4 from being further deformed.

[0027] In the disclosed embodiment, the connecting plate 3, the fixed foot plate 1, the side plate 4 and the upper support plate 7 are all manufactured by cold-rolled plates and the thickness of the paint film on the outer surface is 60 microns, so that the front suspension lower mounting bracket has higher dimensional accuracy and good corrosion resistance.

[0028] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The fixing bolts 5 used above are common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.

[0029] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
