[0024] Please also read Figures 1 to 3The transmission output end reinforcement structure and the vehicle provided by the utility model are now described. The transmission output end reinforcement structure includes an output shaft housing 2 connected to the side of the casing body 1, and the upper and lower sides of the output shaft housing 2 are respectively provided with side guard plates 3 connected to the casing body 1, and a reinforcing rib plate 4 and a circumferential rib plate 5 are provided between the two side guard plates 3. The reinforcing rib plate 4 is connected to the peripheral wall of the output shaft housing 2 and extends to the side away from the casing body 1. The circumferential rib plate 5 extends along the circumference of the transmission output shaft 6. The reinforcing rib plates 4 and the circumferential rib plates 5 form a cross-arranged rib network reinforcement structure on the outer periphery of the output shaft housing 2.

[0025] The transmission output end reinforcement structure provided in the present embodiment is compared with the prior art. The transmission output end reinforcement structure provided in the present embodiment has side guard plates 3 respectively arranged on the upper and lower sides of the output shaft housing 2, thereby improving the connection strength between the output shaft housing 2 and the casing body 1. A reinforcing rib plate 4 and a circumferential rib plate 5 are arranged between the two side guard plates 3 so as to form a cross-arranged rib network reinforcement structure on the periphery of the output shaft housing 2, thereby achieving structural reinforcement of the periphery of the output shaft housing 2 and meeting the torque output requirement of the transmission output shaft 6. At the same time, the arrangement of the side guard plates 3 and the reinforcing rib plates 4 can also increase the heat dissipation area of ​​the output shaft housing 2, improve the heat dissipation performance of the structure, and ensure the stable operation of the transmission.

[0026] It should be noted that the transmission input shaft and the transmission output shaft 6 are arranged in parallel, the outer shell of the transmission input shaft is defined as the casing body 1, and the outer shell of the transmission output shaft 6 is defined as the output shaft housing 2, and the two are arranged adjacently and integrally formed. Since the output torque of the transmission output shaft 6 is large, the force borne by the output shaft housing 2 is also large, so there is a risk of cracks caused by excessive force.

[0027] In this embodiment, a space for accommodating the output shaft housing 2 is formed between the two side guard plates 3 connected to the outside of the casing body 1, and the circumferential rib plate 5 can form an effect of supporting between the two side guard plates 3, thereby enhancing the structural reinforcement effect on the peripheral part of the output shaft housing 2.

[0028] On this basis, a reinforcing rib plate 4 is further provided between the two side guard plates 3. The plate surface of the reinforcing rib plate 4 can be arranged in parallel with the side guard plate 3, or can have an angle of 5-10 degrees between the side guard plate 3. The extension direction of the reinforcing rib plate 4 is consistent, and they all extend to the side away from the casing body 1, forming a structure that is cross-arranged with the circumferential rib plate 5, that is, a rib network reinforcement structure, which further enhances the structural reinforcement effect on the periphery of the output shaft housing 2, so that the output shaft housing 2 can meet the demand of the transmission output shaft 6 to output a larger torque value.

[0029] The outer periphery of the housing body 1 is also provided with auxiliary ribs 11 extending toward one side of the side guard plate 3. The auxiliary ribs 11 are located on the side of the side guard plate 3 away from the reinforcing rib plate 4. The setting of the auxiliary ribs 11 further strengthens the structure of the position where the side guard plate 3 and the housing body 1 meet, thereby improving the reliability of the connection between the two. The auxiliary ribs 11 can be in a strip structure or a mesh structure.

[0030] At the same time, a protruding outer boss 31 is provided on a side wall of the edge guard plate 3 away from the reinforcing rib plate 4 . The outer boss 31 can effectively improve the structural strength of the edge guard plate 3 and enhance the structural reinforcement performance of the edge guard plate 3 .

[0031] In summary, the rib mesh reinforcement structure can also increase the overall heat dissipation area of ​​the structure, improve the heat dissipation performance of the output shaft housing 2, and avoid excessive heat accumulation inside the output shaft housing 2. In addition, when there is other heat dissipation airflow outside, the side guard plate 3, the reinforcement rib plate 4 and the circumferential rib plate 5 can also guide the airflow, accelerate the heat dissipation, and further enhance the heat dissipation performance of the structure.

[0032] In some possible implementations, the above-mentioned characteristic reinforcing rib plate 4 is adopted as follows Figures 1 to 3 See the structure shown. Figures 1 to 3 The reinforcing rib plate 4 includes two first rib plates 41 and a second rib plate 42 located between the two first rib plates 41 . The two first rib plates 41 are respectively located on the upper and lower sides of the output shaft housing 2 . The first rib plate 41 is connected to the peripheral wall of the housing body 1 .

[0033] In this embodiment, the output shaft housing 2 is integrally formed with the casing body 1, and the output shaft housing 2 has an approximately horizontal upper end face and a lower end face. The output shaft housing 2 is connected to the casing body 1 using the upper end face and the lower end face to increase the connection strength between the two.

[0034] The reinforcing rib plate 4 is a combination of a first rib plate 41 and a second rib plate 42. The first rib plate 41 is connected to the top or bottom of the output shaft housing 2, and is connected to the peripheral wall of the output shaft housing 2 (that is, connected to the upper end face or the lower end face of the output shaft housing 2), and can be connected to the output shaft housing 2 in a structure. The plate surface of the first rib plate 41 can be arranged in parallel with the side guard plate 3, or it can have an angle of 5-10 degrees with the side guard plate 3, that is, an angle that is approximately parallel, to play a role in reinforcing the structure of the output shaft housing 2 at different upper and lower positions.

[0035] The first rib plate 41 is connected to the peripheral wall of the output shaft housing 2, extends to the side of the output shaft housing 2 away from the housing body 1, and can be connected to the peripheral wall of the output shaft housing 2. The plate surface of the second rib plate 42 and the first rib plate 41 can be arranged in parallel, or at a small angle, so that the outer side of the peripheral wall of the output shaft housing 2 can be structurally reinforced. The housing body 1 and the output shaft housing 2 are integrally formed, and combined with the arrangement of the first rib plate 41 and the second rib plate 42, the entire peripheral part of the output shaft housing 2 can be structurally reinforced.

[0036] At the same time, the plate surfaces of the first rib plate 41 and the second rib plate 42 are respectively perpendicular or nearly perpendicular to the circumferential rib plate 5, and the circumferential rib plate 5 arranged between the two side guard plates 3 is cross-arranged with the above-mentioned first rib plate 41 and the second rib plate 42, forming a rib mesh reinforcement structure between the two side guard plates 3, further enhancing the structural reinforcement effect of the output shaft housing 2.

[0037] At the same time, the rib mesh reinforcement structure has a larger cross-sectional area, which effectively extends the surface area of ​​the output shaft housing 2, enhances the heat dissipation performance of the structure, and facilitates ensuring the stability of equipment operation.

[0038] In some embodiments, see Figures 1 to 3 The first rib plate 41 is protruded from the second rib plate 42 toward the outer end of the transmission output shaft 6, and the side guard plate 3 is protruded from the first rib plate 41 toward the outer end of the transmission output shaft 6. The second rib plate 42 is protruded from the first rib plate 41 toward the side away from the housing body 1, and the first rib plate 41 is protruded from the side guard plate 3 toward the side away from the housing body 1.

[0039] In this embodiment, the first rib plate 41 and the second rib plate 42 may adopt a triangular, trapezoidal or other shaped plate structure. The horizontal projection area of ​​the second rib plate 41 is greater than the horizontal projection cross-sectional area of ​​the second rib plate 42. For the convenience of description, the side of the output shaft housing 2 adjacent to the housing body 1 is defined as the inner side, and the side of the output shaft housing 2 away from the housing body 1 is defined as the outer side. The end of the transmission output shaft 6 extending outward from the housing body 1 is defined as the outer end, and the end of the transmission output shaft 6 located at the housing body 1 is defined as the inner end.

[0040] When designing the dimensions of the side guard plate 3, the first rib plate 41 and the second rib plate 42, the connection requirements between the transmission output shaft 6 and the external structure should be considered. The length of the second rib plate 42 located outside the transmission output shaft 6 is consistent with the axial length of the output shaft housing 2. The length of the second rib plate 42 in this direction can be appropriately increased, while the side guard plate 3 has the maximum extension length toward the outer end of the output shaft housing 2, ensuring a reliable connection between the housing body 1 and the output shaft housing 2, and having a good structural reinforcement effect.

[0041] Furthermore, while satisfying the structural reinforcement function of the output shaft housing 2, the overall space occupied by the structure should be minimized as much as possible. The length of the side guard plate 3 extending to the outside of the output shaft housing 2 is relatively small to avoid excessive occupation of the outer space. According to the trend of the peripheral wall of the output shaft housing 2 extending outward, the first rib plate 41 is arranged to protrude from the side guard plate 3 to the outside of the output shaft housing 2, and the second rib plate 42 is arranged to protrude from the first rib plate 41 to the outside of the output shaft housing 2, thereby ensuring that the outer periphery of the output shaft housing 2 can be effectively strengthened to meet the torque output requirement of the transmission output shaft 6.

[0042] For some possible implementations, see Figures 1 to 3 The thickness of the second rib plate 42 is greater than the thickness of the edge guard plate 3 , the thickness of the circumferential rib plate 5 is greater than the thickness of the second rib plate 42 , and the thickness of the first rib plate 41 is greater than the thickness of the circumferential rib plate 5 .

[0043] In this embodiment, the thickness of the edge guard plate 3, the first rib plate 41, the second rib plate 42 and the circumferential rib plate 5 are not the same. The plate thickness of each structure is designed according to the requirements of the reinforcement part. The first rib plate 41 mainly reinforces the upper and lower sides of the output shaft housing 2. The area covered by the peripheral wall of the output shaft housing 2 is large, and a larger thickness should be used, such as a rib plate thickness of 7-9 mm, so that the output shaft housing 2 can resist stress in the upper and lower directions and improve the structural strength.

[0044] For the second rib plate 42, a thickness of 6-7 mm can be selected, and the circumferential rib plate 5 also adopts a thickness of 6-7 mm, which can achieve the structural reinforcement effect on the outer peripheral wall of the output shaft housing 2. For the side guard plate 3, a thickness of 5-6 mm can meet the structural strength effect. The above-mentioned different thicknesses are set in different parts, which not only ensures the performance of the output shaft housing 2 in resisting torsion, but also reduces the material consumption, which is convenient for realizing the lightweight design of the transmission.

[0045] In some possible implementations, the above-mentioned characteristic output shaft housing 2 is adopted as follows Figures 1 to 3 See the structure shown. Figures 1 to 3 The output shaft housing 2 is provided with a reinforcing boss 21 located on the outer periphery of the transmission output shaft 6 , the reinforcing boss 21 is connected to the peripheral wall of the casing body 1 , and the second rib plate 42 extends along the axial direction of the transmission output shaft 6 to be connected to the peripheral wall of the reinforcing boss 21 .

[0046] In this embodiment, the reinforcing boss 21 can structurally strengthen the part of the output shaft housing 2 close to the outer end of the transmission output shaft 6, thereby improving the torque resistance of this part. Combined with the structure in which the second rib plate 42 is connected to the reinforcing boss 21, the structural strength of the part of the output shaft housing 2 that is subjected to greater force is further improved, the force is effectively dispersed, good mechanical structural performance is ensured, and the stability of the transmission operation is improved.

[0047] On this basis, the reinforcing boss 21 extends toward one side of the casing body 1 and connects with the outer peripheral wall of the casing body 1, thereby enhancing the connection effect with the casing body 1 and improving the structural strength of the corresponding position of the output shaft housing 2, so that the output shaft housing 2 meets the torque transmission requirements of the transmission.

[0048] In some possible implementations, the above-mentioned characteristic output shaft housing 2 is adopted as follows Figures 1 to 3 See the structure shown. Figures 1 to 3 The end of the output shaft housing 2 is provided with a flange 22 extending toward the periphery. The flange 22 is arranged close to the inner end of the transmission output shaft 6 . The reinforcing rib plate 4 extends toward the side away from the casing body 1 to the edge of the flange 22 .

[0049] In this embodiment, the flange 22 on the outer periphery of the output shaft housing 2 is used to connect with other external components. The flange 22 can play a structural reinforcement role on the end of the output shaft housing 2. At the same time, the reinforcing rib plate 4 is extended to the side away from the casing body 1 to the edge of the flange 22, further enhancing the ability of the output shaft housing 2 to resist torsional deformation.

[0050] In some embodiments, the above-mentioned characteristic edge guard plate 3 can be adopted as follows Figures 1 to 3 See the structure shown. Figures 1 to 3 The two side guard plates 3 are connected to the upper and lower edges of the flange 22 one by one. The side guard plates 3 are connected to the upper and lower edges of the flange 22, and can be connected to the structure to form a three-dimensional support effect, thereby improving the ability of the output shaft housing 2 to resist deformation.

[0051] In some possible implementations, the characteristic circumferential rib plate 5 is as follows: Figures 1 to 3 See the structure shown. Figures 1 to 3 A plurality of circumferential ribs 5 are arranged at intervals along the axial direction of the transmission output shaft 6 , and the plate surfaces of the plurality of circumferential ribs 5 are parallel to each other and are respectively arranged perpendicular to the main axis of the transmission output shaft 6 .

[0052] In this embodiment, the circumferential ribs 5 extend along the circumference of the output shaft housing 2, and a plurality of circumferential ribs 5 are provided to cross each other with the reinforcing ribs 4 to form a rib net reinforcement structure. The rib net reinforcement structure is used to improve the structural strength of the output shaft housing 2 and meet the torque output requirements of the output shaft housing 2.

[0053] Based on the same inventive concept, the embodiment of the present application also provides a vehicle, which includes a transmission output end reinforcement structure. The vehicle improves the connection strength between the output shaft housing 2 and the casing body 1 by respectively arranging side guard plates 3 on the upper and lower sides of the output shaft housing 2. The reinforcing rib plate 4 and the circumferential rib plate 5 arranged between the two side guard plates 3 can form a cross-arranged rib network reinforcement structure on the periphery of the output shaft housing 2, thereby improving the overall structural strength of the output shaft housing 2 and meeting the torque output requirements of the transmission output shaft 6. At the same time, the arrangement of the side guard plate 3 and the reinforcing rib plate 4 can also increase the heat dissipation area of ​​the output shaft housing 2, improve the heat dissipation performance of the structure, and ensure the stable operation of the transmission.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
