Description

Technical Field

[0001] This utility model belongs to the field of bushing technology, specifically a steering bushing. Background Technology

[0002] As an important system in a car, the steering system is responsible for converting the driver's rotational movements into the swinging of the steering rocker arm, which in turn drives the steering tie rod, steering knuckle arm, and steering knuckle. It is a crucial mechanism for safe driving.

[0003] Currently, complaints about poor sealing and noise in the domestic automotive industry remain high, largely due to the sealing between the intermediate shaft and the dust cover in the current steering system. Generally, the dust cover is directly installed on the intermediate shaft, and its waterproof and noise reduction performance is unsatisfactory during use, which greatly affects the stability of the vehicle itself as well as the comfort and safety of the driver. To address this, we propose a steering bushing. Utility Model Content

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Example 1

[0024] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a steering bushing, including a bushing body 100, which is injection molded from PA66-GF25 material. A sealing mechanism is provided on the bushing body 100, and the sealing mechanism includes a sealing component. The sealing component includes a rubber sealing ring 200 sleeved on the outside of the bushing body 100. The rubber sealing ring 200 increases the sealing effect between the bushing body 100 and the external protective cover. A first rubber ring 204 and a second rubber ring 209 are respectively fixedly provided on the inner walls of both sides of the bushing body 100. The first rubber ring 204 and the second rubber ring 209 can increase the sealing effect between the inner walls of both sides of the bushing body 100 and the intermediate shaft and increase the friction between them, thereby reducing the possibility of the bushing body 100 moving on the intermediate shaft during later use.

[0025] Both sides of the outer wall of the rubber sealing ring 200 are fitted with a retaining band 201, and the front of the rubber sealing ring 200 is provided with two sets of spiral plates 207. Both ends of the retaining band 201 pass through the interior of the spiral plate 207.

[0026] The inside of the spiral plate 207 is connected to a locking screw 208 by a thread. The locking screw 208 can fix the two ends of the two sets of cassettes 201 together with the spiral plate 207. The working end of the locking screw 208 extends to the surface of the cassette 201.

[0027] Multiple sets of rubber protrusions 203 are evenly arranged on one inner wall of the bushing body 100 along the circumferential direction. The rubber protrusions 203 can further increase the friction between the bushing body 100 and the intermediate shaft, thereby reducing the rigidity of the bushing body 100 installed on the intermediate shaft.

[0028] Example 2

[0029] Please refer to Example 1. Figures 1-3 Two sets of clamping components are provided on one side of the bushing body 100. The clamping components include an arc plate 202 that is rotatably disposed on one side of the bushing body 100 via a damping shaft, and an L-shaped plate 206 is also fixedly disposed on one side of the bushing body 100.

[0030] The interior of the L-shaped plate 206 is connected to a spiral post 205 by threads, and the working end of the spiral post 205 extends to the outer wall surface of the arc-shaped plate 202.

[0031] This utility model combines the designed bushing body 100 with a sealing mechanism. During use, the bushing body 100 is located outside the intermediate shaft and between the protective cover, which enables the intermediate shaft and the protective cover to play a good role in waterproofing, sealing and noise reduction. In addition, the clamping parts also facilitate the disassembly and assembly of the bushing body 100 and the intermediate shaft, making it convenient to use.

[0032] Example 3

[0033] Please refer to Example 2. Figure 1 , Figure 2 and Figure 4 The inner wall of the bushing body 100 is fixedly provided with multiple sets of protruding strips 300 and multiple sets of limiting blocks 301, and the protruding strips 300 are concave structures.

[0034] This utility model combines a protruding strip 300 and a limiting block 301. After the bushing body 100 is installed on the intermediate shaft, the protruding strip 300 and the limiting block 301 are embedded into the corresponding grooves in the intermediate shaft. The protruding strip 300 and the limiting block 301 can not only position the bushing body 100 during installation, but also prevent the bushing body 100 from rotating during subsequent use, thus improving the performance of the bushing body 100.

[0035] Working principle and usage process of this utility model:

[0036] In use, the bushing body 100 is fitted onto the intermediate shaft, and the rubber sealing ring 200 is fitted onto the outside of the bushing body 100 at a suitable position. Then, two sets of clamping straps 201 are respectively fitted onto the outer walls of both sides of the rubber sealing ring 200, and both ends of the clamping straps 201 are passed through the inside of the U-shaped plate 207. The clamping straps 201 are pulled tight, and then the locking screw 208 is rotated downward to tighten it. At this time, the working end of the locking screw 208 contacts and clamps the end of the clamping strap 201. The rubber sealing ring 200 is installed on the bushing body 100 through the two sets of clamping straps 201. Finally, the protective cover is fitted onto the outside of the rubber sealing ring 200. The bushing body 100 increases the waterproof, sealing and noise reduction between the intermediate shaft and the protective cover, and the rubber sealing ring 200 increases the waterproof, sealing and noise reduction between the bushing body 100 and the inner wall of the protective cover.

[0037] After the bushing body 100 is installed, rotate the arc plate 202 to the middle position on the left. Then the inner wall of the arc plate 202 will contact the outer wall of the intermediate shaft. Then rotate the spiral column 205 closer to the intermediate shaft. Then the working end of the spiral column 205 will contact and press against the arc plate 202. At this time, the bushing body 100 is fixed at the intermediate shaft by the arc plate 202. When it is necessary to disassemble the bushing body 100 later, the operation can be carried out in the opposite way.

[0038] During the installation of the bushing body 100, after the bushing body 100 is installed on the intermediate shaft, it is embedded in the corresponding groove in the intermediate shaft by the protrusion 300 and the limiting block 301. The protrusion 300 and the limiting block 301 can not only position the bushing body 100 during the installation process, but also prevent the bushing body 100 from rotating and displacing during subsequent use, further increasing the stability of the bushing body 100 during use.

[0039] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
