Description

Technical Field

[0001] The utility model relates to the technical field of transmission shaft support assemblies, in particular to a maintenance-free and water-proof transmission shaft intermediate support assembly. Background Art

[0002] The drive shaft is a high-speed, less-supported rotating body, so its dynamic balance is crucial. Generally, the drive shaft must be subjected to a dynamic balance test before leaving the factory and adjusted on a balancing machine. For front-engine, rear-wheel-drive vehicles, it is the shaft that transmits the rotation of the transmission to the main reducer. It can have several sections, and the sections can be connected by universal joints. The drive shaft support assembly is an automotive component used to support the rotation of the drive shaft.

[0003] The drive shaft support assembly is generally located at the bottom of the car. When the car passes through a flooded section of road, the support assembly will be soaked in water. The soaked support assembly will have a certain impact on the operation of the drive shaft, hindering the normal driving of the car. It itself will also be damaged by water, affecting its service life.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0005] In view of the above background technology, the prior art has the disadvantages that the existing transmission shaft support assembly is easily damaged by water immersion, which has a certain impact on the normal operation of the transmission shaft.

[0006] The utility model discloses a maintenance-free and water-proof transmission shaft intermediate support assembly, comprising a mounting bracket, a fixed bracket being provided below the mounting bracket, a honeycomb rubber pad being fixedly connected inside the fixed bracket, a bearing seat being fixedly connected inside the honeycomb rubber pad, a bearing being fixedly connected inside the bearing seat, a control box being fixedly connected inside the fixed bracket, a control rod being rotatably plugged inside the control box, the outer circumferential surface of the control rod being threadedly connected to two threaded tubes, the outer circumferential surface of each of the threaded tubes being fixedly connected to two connecting plates, and the bottom surface of each connecting plate being fixedly connected to an arc plate.

[0007] By adopting the above scheme, since the existing transmission shaft support assembly is easily damaged by water immersion, which has a certain impact on the normal operation of the transmission shaft, the control rod drives the threaded tube to move in the relative direction during the rotation process, prompting the connecting plate to drive the arc plate and the honeycomb rubber pad and the waterproof cover to open and close, thereby providing waterproof protection for the support assembly.

[0008] Optionally, a honeycomb rubber pad 2 is fixedly connected to the inner circumference of the arc-shaped plate, and a waterproof cover is fixedly connected to the inner circumference of the honeycomb rubber pad 2.

[0009] By adopting the above solution, the interior of the support assembly is waterproofed by the waterproof cover and the honeycomb rubber pad 2. At the same time, the honeycomb rubber pad 2 can also meet the up and down vibration requirements of the transmission shaft, avoiding the conflict between the rotating shaft and the curved plate when the car vibrates.

[0010] Furthermore, one side of the honeycomb rubber pad 2 close to the bearing seat contacts the outer surface of the bearing seat, wherein the left sides of the two honeycomb rubber pads 2 are fixedly connected with two connecting heads, and the interiors of the two honeycomb rubber pads 2 are provided with two connecting grooves.

[0011] By adopting the above solution, a gap between the second honeycomb rubber pad and the bearing seat is avoided, and a gap between the second honeycomb rubber pads on both sides is also avoided, which causes rainwater to enter the interior of the support assembly and cause damage to the support assembly.

[0012] Furthermore, a handle is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the handle is provided with anti-slip grooves arranged at equal distances.

[0013] By adopting the above solution, it is convenient for the user to directly rotate the control rod through the handle without the need for external tools, and the friction between the handle and the hand is increased to prevent the hand from slipping.

[0014] Furthermore, a limiting ring is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the limiting ring is rotatably connected to the interior of the control box.

[0015] By adopting the above solution, the control rod is restricted, the sliding and deviation of the control rod is avoided, and the stability of the movement of the control rod is increased.

[0016] Furthermore, two limiting grooves are provided inside the control box, and the outer surface of the connecting plate is slidably connected to the control box via the limiting grooves.

[0017] By adopting the above solution, the threaded tube is restricted to prevent the threaded tube from rotating along with the control rod, so that the connecting plate is always kept in lateral movement.

[0018] Furthermore, the outer circumferential surface of the control rod is provided with two sections of threaded structures, and the threaded tracks of the two sections of threaded structures on the outer circumferential surface of the control rod are in opposite directions.

[0019] By adopting the above scheme, the threaded pipes on both sides are prompted to move in relative directions at the same time, thereby driving the arc plate and the honeycomb rubber pad and the waterproof cover to open and close.

[0020] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0021] 1. The utility model drives the threaded tube to move in the relative direction during the rotation of the control rod, so that the connecting plate drives the arc plate and the honeycomb rubber pad 2. The waterproof cover is opened and closed, thereby achieving the effect of waterproof protection of the support assembly and preventing the interior of the support assembly from being easily immersed in water, solving the problem that the existing transmission shaft support assembly is easily damaged by water immersion, which has a certain impact on the normal operation of the transmission shaft.

[0022] 2. The utility model has a simple structure and is easy to use. It can provide waterproof protection for the drive shaft support assembly to prevent the interior of the drive shaft support assembly from being easily soaked by water, causing damage to the support assembly itself, affecting the normal operation of the drive shaft and the normal driving of the car, extending the service life of the support assembly, and eliminating the need for frequent maintenance of the support assembly, thereby reducing the maintenance burden on the driver.

[0030] See also Figure 1- Figure 4 The utility model discloses a maintenance-free and water-proof transmission shaft intermediate support assembly, including a mounting bracket 1. Specifically, the mounting bracket 1 is provided with equidistantly arranged positioning grooves, and the mounting bracket 1 can be installed and connected to the automobile component through the positioning grooves. A fixing bracket 2 is provided below the mounting bracket 1. Specifically, the fixing bracket 2 and both sides of the mounting bracket 1 are provided with mounting grooves, and the fixing bracket 2 can be installed and connected to the mounting bracket 1 through the mounting grooves. A honeycomb rubber pad 3 is fixedly connected inside the fixing bracket 2, a bearing seat 4 is fixedly connected inside the honeycomb rubber pad 3, and a bearing 5 is fixedly connected inside the bearing seat 4.

[0031] In this embodiment, the rotating shaft can be installed inside the bearing 5. When the car is bumped and vibrated during driving, the transmission shaft will vibrate accordingly. The force generated by the vibration of the transmission shaft will act on the honeycomb rubber pad 3, and the honeycomb rubber pad 3 will then deform to avoid conflict between the transmission shaft and other components when it vibrates.

[0032] The interior of the fixed bracket 2 is fixedly connected to a control box 6, and a control rod 7 is rotatably inserted inside the control box 6. A handle 8 is fixedly sleeved on the outer circumference of the control rod 7, and the outer circumference of the handle 8 is provided with equidistantly arranged anti-slip grooves. The control rod 7 can be rotated by the handle 8 to avoid the use of external tools. A limit ring 9 is fixedly sleeved on the outer circumference of the control rod 7, and the outer circumference of the limit ring 9 is rotatably connected to the interior of the control box 6 to limit the control rod 7, avoid sliding and deflection of the control rod 7, and increase the stability of the movement of the control rod 7.

[0033] like Figure 2 and Figure 4 As shown, the outer circumference of the control rod 7 is threadedly connected to two threaded tubes 10, and the outer circumference of each threaded tube 10 is fixedly connected to two connecting plates 11. Two limiting grooves 12 are provided inside the control box 6. The outer surface of the connecting plate 11 is slidably connected to the control box 6 through the limiting grooves 12, which restricts the threaded tube 10 to prevent the threaded tube 10 from rotating with the control rod 7, so as to enable the connecting plate 11 to always maintain lateral movement.

[0034] The bottom surface of each connecting plate 11 is fixedly connected with an arc plate 13, the inner circumference of the arc plate 13 is fixedly connected with a honeycomb rubber pad 2 14, the inner circumference of the honeycomb rubber pad 2 14 is fixedly connected with a waterproof cover 15, the honeycomb rubber pad 2 14 is in contact with the outer surface of the bearing seat 4 on one side close to the bearing seat 4, and the left sides of the two honeycomb rubber pads 2 14 are fixedly connected with two connecting heads 16, and the interior of the two honeycomb rubber pads 2 14 are provided with two connecting grooves 17, and the positions of the connecting heads 16 and the connecting grooves 17 correspond to each other, and the interior of the support assembly can be waterproofed by the honeycomb rubber pad 2 14 and the waterproof cover 15 to prevent the interior of the support assembly from being easily flooded.

[0035] Specifically, the outer circumferential surface of the control rod 7 is provided with two sections of threaded structures, and the threaded tracks of the two sections of threaded structures on the outer circumferential surface of the control rod 7 are in opposite directions, prompting the threaded tube 10 to move in relative directions, thereby driving the arc plate 13, the honeycomb rubber pad 14, and the waterproof cover 15 to open and close.

[0036] In this embodiment, the control rod 7 can be rotated by the handle 8 to drive the threaded tube 10 to move in the relative direction. The threaded tube 10 drives the arc plates 13 and the honeycomb rubber pad 2 14 and the waterproof cover 15 on both sides to move inward at the same time through the connecting plate 11. Then the honeycomb rubber pad 2 14 and the waterproof cover 15 on both sides will be spliced ​​together, and the inner wall of the waterproof cover 15 will contact the outer circumferential surface of the transmission shaft. The side of the honeycomb rubber pad 2 14 close to the bearing seat 4 will be tightly attached to the bearing seat 4 to avoid water infiltration. When the transmission shaft vibrates, the honeycomb rubber pad 2 14 will be deformed. When the honeycomb rubber pad 2 14 is spliced, the connecting head 16 will be inserted into the connecting groove 17 to avoid gaps at the splicing when the honeycomb rubber pad 2 14 is deformed, which will cause water to infiltrate.

[0037] The above is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
