Description

Technical Field

[0001] This utility model relates to the field of differential technology, and in particular to a highly corrosion-resistant differential housing. Background Technology

[0002] This device is an automotive transmission system component designed for harsh environments, which mainly improves corrosion resistance through material optimization and structural improvements.

[0003] Currently, differential housings and covers are generally connected by bolts. While threaded connections offer some ease of assembly, during vehicle operation, road bumps can easily cause bolts to loosen, creating gaps between the housing and cover. This allows external dust, moisture, and other impurities to easily intrude, further damaging the differential's working environment.

[0004] Meanwhile, the abnormal friction noise generated by the drive components during long-term operation of the differential is an important basis for judging its working status. However, the differential housing lacks effective sound collection and amplification, which often causes the weak friction noise to be masked by other noises when the vehicle is running. This makes it difficult for staff to detect potential faults in the drive components in time by hearing, and makes it impossible to carry out maintenance in the early stages of the fault.

[0005] Therefore, we propose a highly corrosion-resistant differential housing to address the problems mentioned above. Utility Model Content

[0006] This invention proposes a highly corrosion-resistant differential housing to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: including a housing, a fastening mechanism, and a reminder mechanism, wherein the fastening mechanism includes a plug rod and a polygonal block, the rear surface of the polygonal block is fixedly connected to the front end of the plug rod, and the plug rod and the polygonal block are used to fix the disassembly point of the housing to prevent the disassembly point of the housing from becoming loose;

[0008] The reminder mechanism includes a rubber seat and a metal sheet, with the metal sheet located on both sides of the rubber seat. The rubber seat and the metal sheet can remind the staff of the friction status of the drive components inside the housing, so that the staff can repair the drive components in a timely manner.

[0009] Preferably, the fastening mechanism further includes a cross plate, the rear surface of which is fixedly connected to the polygonal block, a positioning rod is fixedly connected to the rear surface of the cross plate, and a rubber ring is sleeved on the outer surface of the insertion rod.

[0010] Preferably, the reminder mechanism further includes a mounting ring, the inner wall of which is fixedly connected to the rubber seat, and a metal plate is provided on the lower surface of the rubber seat, and the upper surface of the metal plate is fixedly connected to the lower surface of the metal sheet.

[0011] Preferably, a cover is fitted onto the front surface of the housing, and a bearing seat is fixedly connected to the front surface of the cover, with the bearing seat corresponding to the internal cavity of the housing.

[0012] Preferably, the front surface of the shell cover is provided with a limiting mechanism, the limiting mechanism includes a limiting tube, and the inside of the limiting tube is fitted and connected to the positioning rod. The inside of the limiting tube is provided with a magnet, and the magnet is attracted to the rear end face of the positioning rod.

[0013] Preferably, the inner thread of the cover is connected to a bolt, and the rear end of the bolt is connected to the inner thread of the cover, and the bolt is located outside the limiting tube.

[0014] Preferably, the front end face of the bolt has a polygonal groove, and the interior of the polygonal groove is fitted and connected with a polygonal block. The interior of the bolt has a fitting groove, and the interior of the fitting groove is fitted and connected with a plug rod.

[0015] Preferably, the outer surface of the mounting ring is provided with a mounting groove, and the interior of the mounting groove is connected to the rubber seat. The rubber seat, the metal sheet, and the metal plate are all mounted around the inner wall of the housing.

[0016] Preferably, the outer surface of the housing is coated with a corrosion-resistant coating, which is made of epoxy resin.

[0017] Preferably, the bearing housing is provided with a bearing inside, and the outer ring of the bearing is movably connected to the inner ring of the bearing housing.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, bolts are used to connect and fix the shell and the cover. The insert rod and the polygonal block can be fitted and limited inside the bolt through the groove and the polygonal slot in layers. Through the fitting of the insert rod and the polygonal block, the cross plate can drive the positioning rod to fit into the inside of the limiting tube. Through the continuous movement of the cross plate, the positioning rod can be attracted by the magnet to fix the positioning rod. With the filling friction of the rubber ring and the inner wall of the fitting groove, the bolt can be limited multiple times to prevent the bolt from loosening and causing gaps at the connection between the shell and the cover, thus reducing the sealing performance of the shell.

[0020] 2. In this utility model, when the drive element inside the housing experiences abnormal friction due to wear, insufficient lubrication, or other issues, it will be accompanied by a friction sound of a specific frequency. The rubber seat can initially transmit and stabilize the friction sound, while the metal sheets on both sides will resonate with the friction sound, amplifying the originally weak friction sound. This allows the staff to clearly perceive the abnormal friction of the drive element. The amplified friction sound serves as a clear warning signal, promptly informing the staff that there is an abnormal friction in the drive element, prompting the staff to quickly inspect and repair the drive element, and preventing damage to the drive element or device malfunction due to the aggravation of friction problems.

[0028] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can also be implemented in other ways than those described herein, and therefore the present invention is not limited to the specific embodiments disclosed in the following specification.

[0030] Example 1, as shown in the attached document Figures 1-6 As shown, it includes a housing 1, a fastening mechanism 8 and a reminder mechanism 4. The fastening mechanism 8 includes a plug 804 and a polygonal block 803. The rear surface of the polygonal block 803 is fixedly connected to the front end of the plug 804. The plug 804 and the polygonal block 803 are used to fix the disassembly point of the housing 1 to prevent the disassembly point of the housing 1 from becoming loose.

[0031] The reminder mechanism 4 includes a rubber seat 402 and a metal sheet 404. The metal sheet 404 is located on both sides of the rubber seat 402. The rubber seat 402 and the metal sheet 404 can remind the staff of the friction of the drive components in the housing 1, so that the staff can repair the drive components in a timely manner.

[0032] The effect achieved by the entire embodiment 1 is as follows: after the housing 1 and the cover 2 are fitted together, the polygonal block 803 and the insert rod 804 can be fitted into the interior of the bolt 6 in layers, so that the bolt 6 can be limited and prevented from loosening during use, thus reducing the sealing performance at the connection between the housing 1 and the cover 2. At the same time, the metal sheet 404 can resonate the sound generated by the friction of the drive element inside the housing 1, amplifying the originally weak friction sound, so that the staff can clearly perceive the abnormal friction of the drive element, and facilitate the staff to repair the drive element in a timely manner.

[0033] Example 2, as Figures 1-5 As shown, the fastening mechanism 8 also includes a cross plate 801, the rear surface of which is fixedly connected to a polygonal block 803. A positioning rod 802 is fixedly connected to the rear surface of the cross plate 801. A rubber ring 805 is fitted on the outer surface of the insertion rod 804. A limiting mechanism 7 is provided on the front surface of the cover 2. The limiting mechanism 7 includes a limiting tube 701, and the interior of the limiting tube 701 is fitted with the positioning rod 802. A magnet 702 is provided inside the limiting tube 701, and the magnet 702 attracts the rear end face of the positioning rod 802. A polygonal groove 10 is provided on the front end face of the bolt 6, and the interior of the polygonal groove 10 is fitted with the polygonal block 803. A fitting groove 9 is provided inside the bolt 6, and the interior of the fitting groove 9 is fitted with the insertion rod 804.

[0034] The overall effect of embodiment 2 is as follows: the bolt 6 can be used to connect and fix the housing 1 and the cover 2. The insert rod 804 and the polygonal block 803 can be fitted and limited inside the bolt 6 through the groove and the polygonal slot 10. Through the fitting of the insert rod 804 and the polygonal block 803, the cross plate 801 can drive the positioning rod 802 to fit into the interior of the limiting tube 701. Through the continuous movement of the cross plate 801, the positioning rod 802 can be attracted by the magnet 702 to fix the positioning rod 802. With the filling friction of the rubber ring 805 and the inner wall of the fitting groove 9, the bolt 6 can be limited multiple times to prevent the bolt 6 from loosening and causing gaps at the connection between the housing 1 and the cover 2, thus reducing the sealing performance of the housing 1.

[0035] Example 3, as Figure 6 As shown, the reminder mechanism 4 also includes a mounting ring 401. The inner wall of the mounting ring 401 is fixedly connected to the rubber seat 402. A metal plate 403 is provided on the lower surface of the rubber seat 402, and the upper surface of the metal plate 403 is fixedly connected to the lower surface of the metal sheet 404. A mounting groove 5 is provided on the outer surface of the mounting ring 401, and the interior of the mounting groove 5 is connected to the rubber seat 402. The rubber seat 402, the metal sheet 404 and the metal plate 403 are all mounted around the inner wall of the housing 1.

[0036] The effect achieved by the entire embodiment 3 is as follows: when the drive element inside the housing 1 experiences abnormal friction due to wear, insufficient lubrication, or other problems, it will be accompanied by a friction sound of a specific frequency. The rubber seat 402 can initially transmit and stabilize the friction sound, while the metal sheets 404 on both sides will resonate with the friction sound, amplifying the originally weak friction sound, so that the staff can clearly perceive the abnormal friction of the drive element. The amplified friction sound serves as a clear reminder signal, which can promptly inform the staff that there is an abnormal friction in the drive element, prompting the staff to quickly check and repair the drive element, and avoid damage to the drive element or device failure due to the aggravation of friction problems.

[0037] Example 4, as Figure 1 As shown, a cover 2 is fitted onto the front surface of the housing 1, and a bearing seat 3 is fixedly connected to the front surface of the cover 2. The bearing seat 3 corresponds to the internal cavity of the housing 1. A bearing 11 is installed inside the bearing seat 3, and the outer ring of the bearing 11 is movably connected to the inner ring of the bearing seat 3. A bolt 6 is threaded inside the cover 2, and the rear end of the bolt 6 is threaded inside the housing 1. The bolt 6 is located outside the limiting tube 701. The outer surface of the housing 1 is coated with a corrosion-resistant coating, which is made of epoxy resin.

[0038] The overall effect achieved by embodiment 4 is as follows: the outer surface of the housing 1 is coated with a corrosion-resistant epoxy resin coating, which forms a protective film on the outer surface of the housing 1, isolating the contact between corrosive gases and other harmful substances in the external environment and the metal surface of the housing 1, thus achieving high corrosion resistance for the housing 1. The bolt 6 is tightened to allow it to penetrate the cover 2 and extend into the interior of the housing 1 for fixed installation. The drive shaft inside the differential housing 1 passes through the internal cavity of the housing 1 and is fixedly connected to the inner ring of the bearing 11. When the drive shaft rotates to transmit torque, the outer ring of the bearing 11 and the bearing seat 3 remain relatively stationary, while the inner ring rotates synchronously with the drive shaft. The rolling friction characteristics of the bearing 11 reduce the frictional resistance during the transmission process, ensuring that the differential transmission assembly can operate efficiently and smoothly.

[0039] The working principle of the entire device is as follows: The outer surface of the housing 1 is coated with a corrosion-resistant epoxy resin coating, which forms a protective film on the outer surface of the housing 1. The drive shaft inside the differential housing 1 passes through the internal cavity of the housing 1 and is fixedly connected to the inner ring of the bearing 11. The drive element can be installed in the cavity of the housing 1. The housing 1 and the cover 2 can be connected by bolts 6. The insert rod 804 and the polygonal block 803 can be fitted and limited inside the bolt 6 through the groove and the polygonal slot 10. Through the fitting of the insert rod 804 and the polygonal block 803, the cross plate 801 can drive the positioning rod 802 to fit into the inside of the limiting tube 701 and attract each other to fix the cover 2.

[0040] The rubber seat 402 can initially transmit and stabilize the friction sound, while the metal sheets 404 on both sides will resonate with the friction sound, amplifying the originally weak friction sound, so that the staff can clearly perceive the abnormal friction of the drive component. The amplified friction sound serves as a clear reminder signal, which can promptly inform the staff that there is an abnormal friction of the drive component, prompting the staff to quickly check and repair the drive component.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
