Description

Technical Field

[0001] This utility model relates to the field of bushing technology, specifically to a support rod bushing. Background Technology

[0002] In recent years, with increasingly fierce competition in the automotive market, OEMs have been demanding that suppliers provide high-performance, stable-quality, and inexpensive components. As a sound insulation and vibration damping component of the steering system, the support rod bushing primarily serves to secure and dampen the support rod within the steering system. The support rod, moving with the steering system, generates rotational friction on the bushing. With prolonged use and increased vibration amplitude, the bushing will wear down, eventually producing noise, reducing the vehicle's sound insulation effect, and thus shortening the bushing's lifespan. Therefore, a new support rod bushing is proposed to address these issues. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 As shown, this utility model provides a support rod bushing, including a bushing body 1, a plurality of pressing blocks 2 are provided around the lower part of the bushing body 1, and a reinforcing rib 5 is provided inside the upper part of the bushing body 1. At the same time, a hemispherical groove 4 is opened inside the bushing body 1. A plurality of telescopic components 8 and a positioning block 7 are inserted into the hemispherical groove 4. A spring 9 is provided on the outer sleeve of the telescopic component 8. The telescopic end of the telescopic component 8 is fixedly connected to the middle of one end face of the positioning block 7. One end of the spring 9 is placed on the inner wall of the hemispherical groove 4, and the other end of the spring 9 is placed on one end of the positioning block 7. A ball 6 is inserted into the other end of the positioning block 7, and the other side of the ball 6 extends beyond the bottom surface of the hemispherical groove 4.

[0024] In this embodiment, an inner hollow portion 101 is provided above the bushing body 1, and multiple reinforcing ribs 5 are fixedly connected above the inner hollow portion 101. At the same time, the upper plane of the reinforcing ribs 5 is flush with the upper plane of the bushing body 1.

[0025] A reinforcing rib 5 is connected inside the upper part of the bushing body 1, which increases the toughness of the entire upper part of the bushing body 1 during use, while saving manufacturing materials.

[0026] In this embodiment, a plurality of grooves 401 are provided in the hemispherical groove 4, and the grooves 401 are arranged in a ring array in the hemispherical groove 4.

[0027] Furthermore, the bottom of the inner bottom of the groove 401 is fixedly connected to the bottom of the telescopic component 8 and one end of the spring 9, and there is a distance between the outer wall of the spring 9 and the inner wall of the groove 401.

[0028] Furthermore, a sliding connection positioning block 7 is inserted into the groove 401, and the other end face of the positioning block 7 is flush with the inner plane of the hemispherical groove 4.

[0029] Multiple telescopic components 8 and springs 9 are provided in the hemispherical groove 4, and the other end of the spring 9 is connected to the positioning block 7. When the positioning block 7 is pressed into the groove 401, the spring 9 can provide support, and the telescopic component 8 is the lowest position where the positioning block 7 is pressed in.

[0030] Furthermore, an arc-shaped groove 701 is provided in one end of the positioning block 7, and the rotatable connecting ball 6 is engaged in the arc-shaped groove 701.

[0031] After the ball 6 is inserted into the positioning block 7, the ball 6 will contact the top of the support rod. When the support rod is working, it will press and rotate against the hemispherical groove 4, so the support rod will press on the ball 6, reducing the friction between the support rod and the hemispherical groove 4.

[0032] In this embodiment, edge teeth 3 are provided around the side of the bushing body 1.

[0033] In this embodiment, an opening 201 is provided between the clamping blocks 2. The clamping blocks 2 are divided into multiple blocks and are placed around the bottom of the bushing body 1, so that the clamping blocks 2 converge inward. When the support rod is inserted, the multiple clamping blocks 2 press against the outer wall of the support rod.

[0034] Working principle:

[0035] A hemispherical groove 4 is provided inside the bushing body 1. The top end of a support rod is inserted into the hemispherical groove 4. A telescopic component 8 and a spring 9 are installed in a groove 401 opened in the hemispherical groove 4, and the spring 9 is sleeved on the telescopic component 8. At the same time, the two ends of the spring 9 are respectively connected to the bottom of the groove 401 and one end of the positioning block 7. In this way, the positioning block 7 slides in the groove 401 and is supported by the spring 9 and the telescopic component 8. A ball 6 is inserted into the positioning block 7 and can roll in the positioning block 7. Since the bushing body 1 is matched with the shaft, a ball head is provided at the top of the shaft. When the ball head is inserted into the hemispherical groove 4 of the bushing body 1, and the ball head and the hemispherical groove... The inner wall of the support rod and the ball bearing 6 fit together. The support rod will press the ball bearing 6 together with the positioning block 7 into the groove 401. At this time, the positioning block 7 is also subjected to a reaction force by the spring 9, so that the ball bearing 6 is pressed against the top of the support rod. This reduces the friction between the top of the support rod and the inner wall of the hemispherical groove 4. When the support rod is working, the ball head reduces the friction on the inside of the bushing body 1 under the action of the ball bearing 6. When the force of the support rod is too large, the positioning block 7 will press the telescopic component 8 to the bottom. At this time, the telescopic component 8 is the lowest position of the positioning block 7. In this way, multiple positioning blocks 7 are distributed on the top surface of the support rod, preventing the top of the support rod from breaking or cracking the bushing body 1.

[0036] In addition, multiple clamping blocks 2 are provided at one end of the bushing body 1. When the ball head enters the bushing body 1, the clamping block 2 is first opened. After the ball head enters, the clamping block 2 returns to its original position inward, so that the opening of the clamping block 2 is smaller than the ball head to prevent it from falling off. Edge teeth 3 are provided on the side of the bushing body 1 to prevent the product from rotating during use. The groove formed between the tail of the bushing body 1 and the reinforcing rib 5 is for the purpose of reducing glue and injection molding process.
