Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridge housing technology, specifically to a bridge housing that is pressure-resistant and deformation-resistant. Background Technology
[0002] As an important component of the automotive transmission system, the axle housing is mainly used to install components such as the main reducer, differential, and half shafts. It also bears the load of the vehicle and the impact force of the road surface. Its pressure resistance and deformation resistance directly affect the safety and stability of the vehicle.
[0003] In existing technologies, traditional axle housings typically consist of a housing body and connecting arms, with the connection point often being the weakest link in the axle housing structure. When a vehicle encounters complex road conditions or heavy loads during operation, the connection point between the housing body and the connecting arms is prone to deformation or even damage due to stress concentration, severely affecting the service life of the axle housing and the normal operation of the vehicle. Utility Model Content
[0004] In view of the problems existing in the pressure-resistant and deformation-resistant bridge housings, this utility model is proposed.
[0005] Therefore, the purpose of this invention is to provide a pressure-resistant and deformation-resistant bridge housing, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A pressure-resistant and deformation-resistant bridge housing includes a bridge housing body and connecting arms. Two connecting arms are fixedly disposed on both sides of the bridge housing body. Each connecting arm is provided with a first fixing block on both sides near the bridge housing body. A second fixing block is disposed on the outer wall of the bridge housing body at a position corresponding to the first fixing block. The side wall of the first fixing block is provided with an L-shaped groove, and the side wall of the second fixing block is provided with a strip-shaped groove. The first fixing block and the second fixing block are both fixedly connected to the corresponding connecting arm and the bridge housing body through a connecting mechanism. A support mechanism is provided between the first fixing block and the second fixing block.
[0007] Preferably, the connecting mechanism includes bolts, and the bottom of both the L-shaped groove and the strip groove is provided with a circular groove. The bottom of the circular groove is provided with a first threaded hole, and multiple bolts are threaded into the interior of the corresponding first threaded holes. The lower ends of the multiple bolts are threadedly connected to the corresponding connecting arm and the bridge housing body.
[0008] Preferably, the support mechanism includes support rods, two of which are disposed on both sides of the first fixed block. A first round pin passes through the interior of the L-shaped groove, and both ends of the first round pin are fixedly connected to the corresponding support rods. A second round pin passes through the interior of the strip-shaped groove, and both ends of the second round pin are fixedly connected to the ends of the corresponding support rods away from the first round pins. A second threaded hole is provided on the upper inner wall of the L-shaped groove, and a threaded rod is threaded into the interior of the second threaded hole. The lower end of the threaded rod abuts against the side of the first round pin away from the second round pin.
[0009] Preferably, a knob is fixedly sleeved on the upper end of the threaded rod.
[0010] Preferably, the upper end of the bolt is located inside the circular groove.
[0011] Preferably, both connecting arms are integrally formed with the bridge housing body.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model, by adding support rods between the connecting arm and both sides of the axle housing body, can effectively improve the pressure resistance and deformation resistance of the axle housing body, and improve the stability of the axle housing.
[0013] 2. In this utility model, by loosening the threaded rod, the limiting position on the first round pin is released, which allows the first round pin to slide to the vertical end of the L-shaped groove. During this process, the second round pin slides in the strip groove under the pull of the support rod, pulling the first round pin from the vertical end of the L-shaped groove. Then, the second round pin can be pulled out of the strip groove, thus completing the individual disassembly and replacement of the support rod. Attached Figure Description

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0018] This utility model discloses a pressure-resistant and deformation-resistant bridge shell.
[0019] Reference Figure 1-3 A pressure-resistant and deformation-resistant bridge housing includes a bridge housing body 1 and connecting arms 2. Two connecting arms 2 are fixedly disposed on both sides of the bridge housing body 1. Both connecting arms 2 are integrally formed with the bridge housing body 1 to improve the connection strength between the connecting arms 2 and the bridge housing body 1. A first fixing block 4 is provided on both sides of the connecting arms 2 near the bridge housing body 1. A second fixing block 3 is provided on the outer wall of the bridge housing body 1 at a position corresponding to the first fixing block 4. An L-shaped groove 9 is opened on the side wall of the first fixing block 4, and a strip groove 8 is opened on the side wall of the second fixing block 3. The first fixing block 4 and the second fixing block 3 are fixedly connected to the corresponding connecting arms 2 and the bridge housing body 1 through a connecting mechanism. A support mechanism is provided between the first fixing block 4 and the second fixing block 3.
[0020] Reference Figure 1-3 The connecting mechanism includes bolts 12, and the bottom of the L-shaped groove 9 and the strip groove 8 are all provided with circular grooves 13. The bottom of the circular groove 13 is provided with a first threaded hole. Multiple bolts 12 are threaded into the corresponding first threaded holes. The lower ends of the multiple bolts 12 are threadedly connected to the corresponding connecting arm 2 and the bridge housing body 1. The upper ends of the bolts 12 are located inside the circular groove 13, which effectively avoids the bolts 12 protruding and interfering with the sliding of the first circular pin 7 and the second circular pin 6.
[0021] Reference Figure 1-3 The support mechanism includes support rods 5, two support rods 5 are set on both sides of the first fixed block 4, a first round pin 7 is inserted inside the L-shaped groove 9, and both ends of the first round pin 7 are fixedly connected to the corresponding support rod 5, a second round pin 6 is inserted inside the strip groove 8, and both ends of the second round pin 6 are fixedly connected to the end of the corresponding support rod 5 away from the first round pin 7, a second threaded hole is opened on the upper inner wall of the L-shaped groove 9, and a threaded rod 10 is threadedly sleeved inside the second threaded hole, the lower end of the threaded rod 10 abuts against the side of the first round pin 7 away from the second round pin 6, and a knob 11 is fixedly sleeved on the upper end of the threaded rod 10 for easy rotation of the threaded rod 10.
[0022] In this utility model, during use, the first fixing block 4 is first fixed to the connecting arm 2, and the second fixing block 3 is fixed to the bridge housing body 1 through the connecting mechanism. The bolt 12 is passed through the round groove 13 at the bottom of the L-shaped groove 9 of the first fixing block 4 and the first threaded hole, and threadedly connected to the connecting arm 2 to complete the fixing of the first fixing block 4. Similarly, the second fixing block 3 is fixed to the bridge housing body 1 through the bolt 12 to ensure that the positions of the first fixing block 4 and the second fixing block 3 correspond. Then, the support mechanism is installed. The first round pin 7 and the second round pin 6 at both ends of the support rod 5 are aligned with the vertical end of the L-shaped groove 9 and the strip groove 8, respectively. The support rod 5 is pushed so that the first round pin 7 slides into the horizontal end along the vertical end of the L-shaped groove 9, and the second round pin 6 slides into the inside of the strip groove 8 at the same time. The knob 11 is rotated to drive the threaded rod 10 to move downward along the second threaded hole until the lower end of the threaded rod 10 is reached. The first round pin 7 is tightly pressed against the side wall, thus completing the limiting and fixing of the first round pin 7. At this time, the support rod 5 is firmly connected to the first fixing block 4 and the second fixing block 3, forming support at the connection between the bridge housing body 1 and the connecting arm 2, enhancing the pressure resistance and deformation resistance of the bridge housing. When the support rod 5 is deformed and needs to be replaced, the knob 11 is rotated in the opposite direction to move the threaded rod 10 upward, releasing the contact and limiting of the first round pin 7; the support rod 5 is pushed so that the first round pin 7 slides back to the vertical end along the horizontal end of the L-shaped groove 9, and the second round pin 6 slides out from the strip groove 8; then the support rod 5 is pulled upward to remove the first round pin 7 from the vertical end of the L-shaped groove 9, thus completing the disassembly and replacement of a single support rod 5 without disassembling the first fixing block 4 and the second fixing block 3, saving time and effort. After replacing the new support rod 5, the above installation steps are repeated to restore the support function.
[0023] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
