Description

Technical Field

[0001] The utility model relates to the field of differentials, in particular to a differential protection cover which is easy to disassemble and assemble. Background Art

[0002] When a vehicle is driving, the rolling distances of the left and right wheels are often different at the same time, that is, there is a speed difference between the wheels on both sides. Especially when the vehicle turns, the speed difference between the wheels on both sides is more obvious. Differentials are used in various types of vehicles to ensure that the vehicles can turn and drive at different angular velocities.

[0003] The existing differential is mainly composed of a housing, planetary gears, and half-axle gears. The half-axle gears are connected to the drive wheels through half-axles. When driving on relatively good roads, their performance can meet the normal driving of the car.

[0004] However, the existing differential protection cover is installed and fixed with a large number of bolts. When it needs to be repaired, it takes a lot of time and energy to disassemble and assemble it. The removal is difficult and easily increases the maintenance time cost. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0022] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0023] See also Figure 1 , Figure 2 The utility model provides a differential protection cover which is easy to disassemble and assemble, comprising two shells 1. The ends of the two shells 1 which are away from each other are provided with a slide groove 2. The slide groove 2 is an annular groove with a notch. The inner wall of one of the slide grooves 2 is slidably connected with a plurality of connecting plates 3. The outer surface of each connecting plate 3 is slidably connected with the other slide groove 2. Specifically, the two shells 1 can be fixed together by inserting the connecting plate 3 along the notch of the annular groove and rotating the connecting plate 3. The outer surface of each shell 1 is provided with a first slot 7. The inner wall of each first slot 7 is plugged with a first plug rod 4. The connecting plate 3 is fixed on the two shells 1 by plugging the first plug rod 4 with the corresponding first slot 7.

[0024] In a preferred embodiment, the outer surface of each first plug rod 4 is slidably connected to the corresponding connecting plate 3. When the connecting plate 3 is rotated, the first plug rod 4 will slide along the outer surface of the corresponding shell 1. At this time, the first plug rod 4 and the shell 1 are squeezed so that the first plug rod 4 will slide horizontally along the corresponding connecting plate 3. Each first plug rod 4 is fixedly connected to a pull block 18 at one end away from the corresponding shell 1. Specifically, the connecting plate 3 is rotated to make the first plug rod 4 and the corresponding first slot 7 on the same central axis. At this time, the first plug rod 4 enters the corresponding first slot 7 to complete the fixation between the two shells 1. By pulling the pull block 18, the pull block 18 will drive the corresponding first plug rod 4 to leave the corresponding first slot 7, so that the connecting plate 3 can be quickly disassembled.

[0025] In this embodiment, the outer surface of each first plug rod 4 is fixedly connected with a fixing block 5. The setting of the fixing block 5 can increase the force on the first spring 6. The outer surface of each first plug rod 4 is sleeved with a first spring 6. One end of each first spring 6 is fixedly connected to the corresponding fixing block 5, and the other end is fixedly connected to the corresponding connecting plate 3. Specifically, when the connecting plate 3 wraps and fixes the two shells 1, the first spring 6 begins to compress. When the first plug rod 4 and the corresponding first slot 7 are on the same central axis, the first spring 6 will autonomously push the corresponding first plug rod 4 under the action of its rebound force to make it quickly enter the corresponding first slot 7.

[0026] like Figure 2 , Figure 3 As shown, a plurality of first fixed grooves 8 are provided inside each shell 1, and a push block 10 is slidably connected to the inner wall of each first fixed groove 8. By pushing the push block 10, the push block 10 will vertically slide along the corresponding first fixed groove 8. A second spring 9 is fixedly connected to the bottom surface of each push block 10. When the push block 10 is pushed, the push block 10 will drive the corresponding second spring 9 to compress it. The bottom end of each second spring 9 is fixedly connected to the corresponding first fixed groove 8. Specifically, the elastic force of the second spring 9 causes the push block 10 to always be subjected to a vertical upward force.

[0027] Replay Figure 4 The two shells 1 are fixedly connected to one side away from each other with a connecting column 16, which serves as a connecting mechanism for the fixing ring 12. The inner wall of the connecting column 16 is connected to the inner wall of the corresponding shell 1. The outer surface of each connecting column 16 is slidably connected to the fixing ring 12. The installation of the fixing ring 12 can constrain the position of the differential to prevent the parts inside the differential from sliding out. Each fixing ring 12 is provided with a plurality of second slots 13 on the side close to the corresponding shell 1.

[0028] In this embodiment, the upper surface of each push block 10 is fixedly connected with a second plug rod 11, the second plug rod 11 is perpendicular to the corresponding shell 1, the outer surface of each second plug rod 11 is slidably connected to the corresponding first fixed groove 8, the second plug rod 11 can slide vertically along the corresponding first fixed groove 8, and the outer surface of each second plug rod 11 is plugged into the corresponding second slot 13. Specifically, through the plug-in connection between the second plug rod 11 and the corresponding second slot 13, the fixing ring 12 can be quickly fixed and cannot rotate around the connecting column 16.

[0029] In this embodiment, the inner wall of each fixed ring 12 is rotatably connected with a connecting piece 17, which is a connecting part of the differential extending out of the housing 1. The inner wall of each fixed ring 12 is fixedly connected with a plurality of connecting blocks 14, and the connecting blocks 14 are located on the inner wall of the fixed ring 12 and are evenly arranged at the bottom end of the inner wall of the fixed ring 12.

[0030] In this embodiment, a plurality of T-slots 15 are provided on the outer surface of each connecting column 16, and the outer surface of each T-slot 15 is slidably connected with the corresponding connecting block 14. Specifically, the connecting block 14 on the fixing ring 12 is inserted along the corresponding T-slot 15 until the fixing ring 12 contacts the shell 1. At this time, the fixing ring 12 will squeeze the second plug rod 11 to make it slide vertically along the corresponding first fixing groove 8, the second spring 9 begins to compress, and then the fixing ring 12 is rotated. The fixing ring 12 will be clamped with the corresponding T-slot 15 through the connecting block 14 until the second slot 13 and the corresponding second plug rod 11 are on the same central axis. The second spring 9 will push the corresponding second plug rod 11 into the second slot 13 under the action of its rebound force, thereby completing the quick installation of the fixing ring 12.
