[0021] The following will detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the present utility model and are not used to limit the present utility model.
[0022] Please refer to Figures 1-4, in order to solve the problems in the prior art, the present utility model provides a novel automotive gearbox structure 1. The gearbox structure 1 includes a first housing 11, a second housing 12, a speed change gear set 13, bolts 15 and a connection assembly 14. The first housing 11 and the second housing 12 can be covered to form a complete cylindrical barrel. The speed change gear set 13 is installed inside the cylindrical barrel. The first housing 11 is provided with first mounting parts 111 arranged in an array along the circumferential direction of the cylindrical barrel. The second housing 12 is provided with second mounting parts 121 arranged in an array along the circumferential direction of the cylindrical barrel. A first groove 112 is formed on the first housing 11 on one side of the first mounting part 111. A second groove 122 is formed on the second housing 12 on one side of the second mounting part 121. The connection assembly 14 is respectively arranged in the first groove 112 and the second groove 122. The connection assembly 14 includes a first connecting plate 141 and a second connecting plate 142. The first connecting plate 141 is attached to the surface of the cylindrical barrel. One end of the first connecting plate 141 is provided with concentric first connecting part 1411 and second connecting part 1412. The first connecting part 1411 is adapted to the size of the groove. A connection hole aligned with the mounting part is formed at the center of the second connecting part 1412. A protruding slide rail 1413 is arranged on the circumferential surface of the second connecting part 1412. One end of the second connecting plate 142 is rotatably connected to the second connecting plate 142 through the slide rail 1413. A hanging hole 1421 is formed at the other end of the second connecting plate 142. The bolt 15 passes through the connection hole on one side of the first mounting part 111, passes through the second mounting part 121, and is threadedly connected to the connection hole on one side of the second mounting part 121.
[0023] By arranging the connection assembly 14 in the first groove 112 of the first housing 11 and arranging the connection assembly 14 in the second groove 122 of the second housing 12, after the bolt 15 is inserted into the first connecting part 1411 from the connection assembly 14 on one side of the first housing 11, the connection assembly 14 can be fixed on the first housing 11. After the bolt 15 passes through the second connecting part 1412, it can be connected to the connection assembly 14 on one side of the second housing 12, thereby fixing the connection assembly 14 on the second housing 12. At the same time, under the action of the bolt 15, the first housing 11 and the second housing 12 are fixedly connected and the first housing 11 and the second housing 12 form a complete cylindrical barrel.
[0024] In the connecting component 14, since the first connecting plate 141 is attached to the surface of the cylindrical barrel, and the first connecting portion 1411 on one side of the first connecting plate 141 is located in the first groove 112, and the second connecting portion 1412 corresponds to the first mounting portion 111 on the first housing 11. After the bolt 15 is inserted into the second connecting portion 1412 and connected to the first mounting portion 111, the connection firmness between the connecting component 14 and the first housing 11 can be strengthened under the action of the first connecting plate 141 and the first connecting portion 1411. By providing a slide rail 1413 on the second connecting portion 1412, the second connecting plate 142 can rotate around the second connecting portion 1412 through the slide rail 1413, so that the second connecting plate 142 can be rotated to a position where it fits the cylindrical barrel, thereby reducing the occupied space of the connecting component 14 on the cylindrical barrel and preventing the gearbox structure 1 from being unable to be installed on the vehicle due to the size of the connecting component 14 protruding from the cylindrical barrel. By providing a lifting hole 1421 on the second connecting plate 142, when it is necessary to lift the gearbox structure 1 from the vehicle, the angle of the second connecting plate 142 can be rotated to facilitate the lifting device to be connected to the lifting hole 1421 through the hook, and then the lifting device can lift the gearbox structure 1 out of the vehicle through the connecting component 14.
[0025] Compared with the prior art method of using ropes to wind the gearbox, the gearbox structure 1 of the present utility model can directly rotate the second connecting plate 142, so that the lifting device is directly connected to the lifting hole 1421 on the second connecting plate 142 through the hook, and then the gearbox structure 1 is lifted out of the vehicle under the action of the lifting device, simplifying the lifting process of the gearbox, improving the lifting efficiency, and avoiding the risk of the gearbox structure 1 falling off during the lifting process.
[0026] In the embodiment of the present utility model, four slide rails 1413 are arranged in an array along the axial direction of the second connecting portion 1412. A chute 1423 is provided on one side of the second connecting plate 142. The number and size of the chute 1423 are adapted to the slide rails 1413, so that the second connecting plate 142 rotates around the second connecting portion 1412 under the combined action of the four chutes 1423 and the four slide rails 1413. When it is necessary to lift the gearbox structure 1 out of the vehicle, by rotating the second connecting plate 142, the lifting device is connected to the lifting hole 1421 on the second connecting plate 142 through the hook, and the connection firmness between the second connecting plate 142 and the second connecting portion 1412 is increased under the action of the four slide rails 1413, so that the second connecting portion 1412 lifts the cylindrical barrel through the bolt 15, simplifying the lifting process of the gearbox structure 1 and improving the lifting efficiency. When the gearbox structure 1 is installed in the vehicle, the occupied space of the connecting component 14 can be reduced by rotating the second connecting plate 142 to a position where it fits the cylindrical barrel, avoiding interference with the positions of other components of the vehicle.
[0027] In an embodiment of the present utility model, the slide rail 1413 is a dovetail slide rail 1413, and the chute 1423 is a dovetail chute 1423 to prevent the second connecting plate 142 from detaching from the second connecting portion 1412.
[0028] In an embodiment of the present utility model, both the first mounting portion 111 and the first groove 112 are arranged in an array of 6 along the circumferential direction of the first housing 11, and both the second mounting portion 121 and the second groove 122 are arranged in an array of 6 along the circumferential direction of the second housing 12. The positions of the first mounting portion 111 correspond to those of the second mounting portion 121 one by one, and 12 sets of connecting components 14 are provided. Among them, 6 sets of connecting components 14 are respectively located in 6 first grooves 112, and 6 sets of connecting components 14 are respectively located in 6 second grooves 122, so that the hoisting equipment can hoist the gearbox structure 1 from 6 connecting components 14 in the circumferential direction, improving the convenience of hoisting operations.
[0029] In an embodiment of the present utility model, the radian of the slide rail 1413 is 120 degrees for the second connecting plate 142 to rotate from a position where it fits the surface of the cylindrical barrel to a position where it forms a 120-degree angle with the cylindrical barrel. After hoisting the gearbox structure 1 out of the vehicle, by rotating the second connecting plates 142 on both sides of the bottom of the gearbox structure 1, the position of the gearbox structure 1 can be fixed under the support of the second connecting plates 142, preventing the gearbox structure 1 of the cylindrical barrel pile from rotating and displacing on the ground.
[0030] In an embodiment of the present utility model, reinforcing rib plates 1422 are arranged on the surface of the slide rail 1413 along the side of the second connecting plate 142 away from the speed change gear set 13. One end of the reinforcing rib plate 1422 fits on the slide rail 1413 and the width of the reinforcing rib plate 1422 is adapted to the width of the slide rail 1413. Under the action of the reinforcing rib plates 1422, the structural strength of the connecting component 14 is enhanced, preventing the gearbox structure 1 from detaching from the connecting plate assembly due to insufficient structural strength of the connecting component 14. At the same time, under the action of the reinforcing ribs, the support stability of the second connecting plate 142 for the gearbox structure 1 is improved, preventing the second connecting plate 142 from deforming.
[0031] In an embodiment of the present utility model, two reinforcing rib plates 1422 are symmetrically arranged along the width direction of the second connecting plate 142, and the positions of the two reinforcing rib plates 1422 correspond to the positions of two of the slide rails 1413 respectively. Under the action of the slide rail 1413, support is provided for the reinforcing rib plate 1422, and then the reinforcing rib plate 1422 provides support for the second connecting plate 142 through the slide rail 1413, preventing deformation when the second connecting plate 142 supports the gearbox structure 1.
[0032] In an embodiment of the present utility model, the bolt 15 is a 10.9-grade bolt and / or a 12.9-grade bolt, so as to enhance the structural strength of the bolt 15 itself, enabling the first housing 11 and the second housing 12 to be relatively fixed more effectively under the connection of the bolt 15. Meanwhile, the connection components 14 on the first housing 11 and the second housing 12 are fixed, facilitating the hoisting equipment to be directly connected to the hoisting hole 1421 on the second connecting plate 142 through a hook to hoist the gearbox structure 1, thereby improving the hoisting efficiency.
[0033] In the present utility model, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.
