Description

Technical Field

[0001] The utility model relates to the technical field of tractor manufacturing, in particular to a support frame for a wheelhouse mudguard of a tractor cab. Background Art

[0002] At present, with the continuous expansion of the tractor market year by year and the continuous increase in people's requirements for the operating performance of tractors, the overall structure of tractors is also constantly improving.

[0003] As is well known, mudguards need to be provided on both sides of the tractor cab. The assembled mudguards are fixed to the cab by bolts. Due to the strength limitation of the mudguards, support frames need to be added to improve their overall support performance. At present, the support frames for the wheelhouse mudguards of wheeled tractors on the market adopt segmented local strengthening, that is, a mudguard requires multiple support frames, and its overall support performance still needs to be improved. In addition, due to the requirements of Annex XV of EU Regulation (EU) No 1322 / 2014 and the latest amendment (EU) 2016 / 1788, handrails need to be designed for the access passage of the cab. Therefore, a boarding handrail needs to be provided on the wheelhouse, and at least three brackets are required on the inner side of the wheelhouse mudguard. As shown in and, bracket 1 and bracket 3 respectively fix the wheelhouse mudguard from both ends, and bracket 2 is used to fix the boarding handrail. Such a setting of three brackets will bring inconvenience to on-site assembly, and at the same time, multiple materials will be generated, increasing the costs of production manufacturing and warehousing management. Figure 5 and Figure 6 As shown in, bracket 1 and bracket 3 respectively fix the wheelhouse mudguard from both ends, and bracket 2 is used to fix the boarding handrail. Such a setting of three brackets will bring inconvenience to on-site assembly, and at the same time, multiple materials will be generated, increasing the costs of production manufacturing and warehousing management. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the problems in the background art and provide a support frame for a wheelhouse mudguard of a tractor cab. The support frame is of a pipe beam structure, with stable support, and can simultaneously fix installation points A, B, and C to replace the original three brackets, thereby reducing the assembly workload and the number of materials.

[0005] To achieve the above-mentioned utility model purpose, the technical solution adopted by the present utility model is specifically as follows: A support frame for a wheelhouse fender of a tractor, including a frame body with a tubular beam structure, and a steel plate bending part arranged at one end of the frame body. The steel plate bending part is vertically arranged with the frame body, so that linear support can be changed into surface support, and the fixation is more firm. An end connector is arranged at the end of the frame body far from the steel plate bending part, and a middle connector is arranged in the middle of the frame body. The frame body is arc-shaped and is adapted to the inner wall of the wheelhouse fender. Mounting points A, B, and C are respectively arranged on the steel plate bending part, the end connector, and the middle connector. Mounting points A and B are connected to the cab body through bolts passing through the wheelhouse fender. Mounting points A and B are used to fix the wheelhouse fender, and mounting point C is used to fix the boarding handrail above the wheelhouse fender. In this way, while meeting the support strength, the risk of direct force deformation and damage of the wheelhouse fender is avoided.

[0006] Further, the steel plate bending part, the end connector, and the middle connector are all welded to the frame body, which is beneficial to enhancing the connection strength. The frame body is made of a 20X2 square tube, and the steel plate bending part is made of a steel plate with a thickness of 3mm. Welding them together has less mold opening cost and good integrity. While the traditional support frame needs to make stamping die parts and adopts segmented assembly, with poor integrity and an increase in part of the mold opening cost.

[0007] Further, at least two threaded connection holes are arranged on each of the mounting points A, B, and C, and the connection is more stable.

[0008] Further, a mounting point D is also arranged on the steel plate bending part. Such a setting increases the number of mounting points and is beneficial to increasing the connection stability.

[0009] Further, two middle connectors are arranged, respectively on both sides of the frame body.

[0010] Further, the bolt passes through the threaded hole at the mounting point C on the middle connector and the wheelhouse fender and is then connected and installed to the boarding handrail.

[0011] Further, the frame body is vertically arranged with the steel plate bending part.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The support frame uses a tubular beam structure as the main body, and mounting points A, B, and C can be simultaneously installed on the support frame through bolts. Compared with the traditional at least three brackets, the number of brackets used is reduced, the mold opening cost is reduced, the development cost is saved, and at the same time, part of the materials generated are also reduced, saving costs for production manufacturing and warehousing management.

[0014] 2. Additionally, an integrated support structure is adopted, which has high support strength and is also conducive to reducing the assembly and debugging time. That is, for this support frame, the debugging and assembly of the wheelhouse mudguard and the boarding handrail can be completed only by adjusting the bolts at installation point A and installation point B, saving assembly time. While for the traditional bracket, the debugging and assembly of the wheelhouse mudguard and the boarding handrail need to be completed by adjusting the bolts at installation point A, installation point B, and installation point C. Therefore, the traditional bracket assembly adds a process, and its integrity is poor, which will cause the risk of multiple adjustments, increase the assembly time, and reduce the production efficiency.

[0015] 3. According to actual needs, the number of installation points can also be increased to enhance the connection stability. For example, adding installation point D is simple to operate and makes the installation more firm. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment: As Figures 1 - 4As shown in the figure, this embodiment provides a support frame for a wheelhouse fender of a tractor, which includes a frame body 1 with a tubular beam structure and a steel plate bending part 2 arranged at one end of the frame body 1. The steel plate bending part 2 is perpendicularly arranged to the frame body 1, which can change the linear support into a planar support, making the support more firm. An end connector 3 is arranged at the end of the frame body 1 away from the steel plate bending part 2, and a middle connector 4 is arranged in the middle of the frame body 1. The frame body 1 is arc-shaped and is adapted to the inner wall of the wheelhouse fender 5. Installation points A, B, and C are respectively arranged on the steel plate bending part 2, the end connector 3, and the middle connector 4. The installation points A and B are connected to the cab body through bolts passing through the wheelhouse fender 5. The installation points A and B are used to fix the wheelhouse fender 5, and the installation point C is used to fix the boarding handrail 6 above the wheelhouse fender 5. In this way, while meeting the support strength, the risk of direct force deformation and damage of the wheelhouse fender 5 is avoided; an installation point D is also arranged on the steel plate bending part 2, increasing the number of installation points, which is beneficial to increasing the connection stability;

[0026] The steel plate bending part 2, the end connector 3, and the middle connector 4 are all welded to the frame body 1, which is beneficial to enhancing the connection strength. The frame body 1 is made of a 20X2 square tube, and the steel plate bending part 2 is made of a steel plate with a thickness of 3mm. Welding them together has less mold opening cost and good integrity. While the traditional support frame needs to make stamping die parts and adopts segmented assembly, with poor integrity and an increase in part of the mold opening cost; at least two threaded connection holes are arranged on the installation points A, B, and C, making the connection more stable; two middle connectors 4 are arranged, respectively on both sides of the frame body 1. Bolts pass through the threaded holes at the installation point C of the two middle connectors 4 and the wheelhouse fender 5 and then are connected and installed with the boarding handrail 6.

[0027] Therefore, this support frame uses a tubular beam structure as the main body, and the installation points A, B, and C can be simultaneously installed on this support frame through bolts. Compared with the traditional at least three brackets, the number of brackets used is reduced, thus reducing the mold opening cost, saving the development cost, and at the same time reducing the generation of some materials, saving costs for production manufacturing and warehousing management; in addition, adopting an integrated support structure, it has great support strength and is also beneficial to reducing the assembly and debugging time. That is, this support frame only needs to adjust the bolts at the installation points A and B to complete the debugging and assembly of the wheelhouse fender and the boarding handrail, saving the assembly time. While the traditional bracket needs to adjust the bolts at the installation points A, B, and C to complete the debugging and assembly of the wheelhouse fender and the boarding handrail. Therefore, the traditional bracket assembly adds a process, with poor integrity, causing the risk of multiple adjustments, increasing the assembly time, and reducing the production efficiency; according to actual needs, the number of installation points can also be increased, such as adding the installation point D, with simple operation and enhanced connection stability.

[0028] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model.
