Description

Technical Field

[0001] This utility model relates to automobile chassis installation, specifically to an automobile chassis rubber bushing. Background Technology

[0002] Rubber bushings in the automotive chassis are key connecting components in the automotive chassis suspension system, which have a significant impact on vehicle performance and comfort. Currently, automotive bushings are widely used in vehicle suspension systems, steering systems, and transmission systems, mainly for buffering, vibration isolation, and connecting different moving parts.

[0003] However, traditional automotive chassis rubber bushings have some problems during use. On the one hand, their sealing performance is limited, making it difficult to effectively prevent external dust, moisture, impurities, etc. from entering the bushing. These substances will cause corrosion and wear to the internal structure of the bushing and the connection with the chassis, thereby shortening the service life of the bushing. On the other hand, during vehicle operation, the chassis will be subjected to various vibrations and impacts. The structural design of traditional rubber bushings cannot guarantee the stability of its internal sealing ring. The sealing ring is prone to displacement and loosening, which in turn affects the sealing performance of the bushing and the overall buffering and vibration isolation effect. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a rubber bushing for automotive chassis, which solves the problem mentioned in the background art that traditional automotive chassis rubber bushings have limited sealing performance and cannot effectively prevent external dust, moisture, and impurities from entering the bushing, causing erosion and wear on the internal structure and chassis connection parts, thus shortening the service life of the bushing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rubber bushing for an automotive chassis, comprising a bushing body, wherein a sealing ring is installed inside the bushing body; further comprising a movable component for abutting the sealing ring; and a fixed component for restricting the movable component after use; the movable component comprises: a turntable rotatably connected inside the bushing body, a control disc mounted at the bottom of the turntable, the control disc rotatably connected to the bottom of the bushing body, a sliding rod slidably connected to the surface of the turntable, an abutting rod hinged to the outside of the sliding rod, an abutting block mounted on the surface of the abutting rod, and the abutting block slidably connected inside the bushing body.

[0006] Preferably, a rotating shaft is installed on the inner side of the turntable, a sliding rod is slidably connected to the surface of the rotating shaft, an abutment ring is installed on the surface of the sliding rod, and the abutment ring is slidably connected inside the sleeve.

[0007] Preferably, the fixing component includes a limiting ring, which is installed inside the sleeve, and a plurality of limiting blocks are installed on the inner side of the limiting ring.

[0008] Preferably, a slip ring is slidably connected inside the slide rod, and a fixing spring is installed at the bottom of the slip ring, with the fixing spring installed inside the slide rod.

[0009] Preferably, the slip ring surface is fitted with an insert plate, the bottom of the insert plate is fitted with an insert block, and the insert block is inserted into the inner side of several limiting blocks.

[0010] Preferably, the surface of the turntable is provided with a crescent groove, and the surface of the rotating shaft is provided with an arc-shaped groove.

[0011] Preferably, the cross-section of the insert block is triangular, and the cross-section of the contact ring is circular.

[0012] As can be seen from the above technical solutions, the automotive chassis rubber bushing provided in the embodiments of this specification has at least the following beneficial effects:

[0013] 1. This utility model, through the setting of movable components, rotates the control disk to drive the turntable to rotate, and the sliding rod on the turntable slides along the surface. Because it is hinged with the abutment rod, it pushes the abutment rod to move, so that the abutment block slides in the sleeve and abuts the sealing ring, applying force to keep its position stable. At the same time, the rotating shaft drives the sliding rod to make the abutment ring slide up to abut the bottom of the sealing ring. The two work together to firmly abut the sealing ring, preventing it from shifting or loosening. It can prevent external dust and other things from entering the bushing, avoid internal structure corrosion and wear, prevent grease leakage, and extend the bushing's service life.

[0014] 2. This utility model, through the setting of a fixing component, has a limiting ring installed in the sleeve body. The limiting block is a key locking structure. After the movable component completes its contact with the sealing ring, the insert block is inserted into the inner side of the limiting block under the drive of the slip ring. The two engage and fix the relevant movable parts, restricting the rotation or movement of the turntable and other parts, allowing the contact block and contact ring to stably contact the sealing ring. If the contact state needs to be adjusted, such as for sealing ring maintenance or chassis structure changes, external force is applied to the insert plate to overcome the elasticity and pull it upward, causing the insert block to disengage from the limiting block and unlock. After adjustment, the insert plate is released to reset the insert block and achieve relocking, thus improving the sealing performance and stability of the connection between the sealing ring and the sleeve body.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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] Example 1

[0024] Please see Figure 1 - Figure 3 As shown, a rubber bushing for an automobile chassis includes a bushing body 1, and a sealing ring 2 is installed inside the bushing body 1.

[0025] It also includes a movable component 3 for abutting the sealing ring 2;

[0026] Fixed component 4 is used to restrict the active component 3 after use;

[0027] First, the active component 3 includes: a turntable 31, which is rotatably connected inside the sleeve 1. A control disk 32 is installed at the bottom of the turntable 31 and is rotatably connected to the bottom of the sleeve 1. A slide rod 33 is slidably connected to the surface of the turntable 31. An abutment rod 34 is hinged to the outside of the slide rod 33. An abutment block 35 is installed on the surface of the abutment rod 34 and is slidably connected inside the sleeve 1. A rotating shaft 36 is installed inside the turntable 31. A slide rod 37 is slidably connected to the surface of the rotating shaft 36. An abutment ring 38 is installed on the surface of the slide rod 37 and is slidably connected inside the sleeve 1. During the rotation of the rotating shaft 36, the arc-shaped groove 360 ​​on its surface guides the sliding of the slide rod 37, making the movement of the abutment ring 38 more precise and stable.

[0028] In this embodiment, the movable component 3 enables the rotating control disk 32 to drive the turntable 31 to rotate. The sliding rod 33 on the turntable 31 slides along its surface and, due to its hinged connection with the abutment rod 34, pushes the abutment rod 34 to move, causing the abutment block 35 to slide within the sleeve 1 and abut against the sealing ring 2, applying force to maintain its position. Simultaneously, the rotating shaft 36 drives the sliding rod 37 to cause the abutment ring 38 to slide upwards and abut against the bottom of the sealing ring 2. The two components work together to firmly abut against the sealing ring 2, preventing displacement and loosening. This prevents external dust and other contaminants from entering the bushing, avoiding corrosion and wear to the internal structure, preventing grease leakage, and extending the bushing's lifespan.

[0029] Example 2

[0030] Please see Figure 4 - Figure 5 As shown, the fixing component 4 includes: a limiting ring 41, which is installed inside the sleeve 1, and a plurality of limiting blocks 42 are installed on the inner side of the limiting ring 41.

[0031] Secondly, a slip ring 43 is slidably connected inside the slide rod 33. A fixing spring 44 is installed at the bottom of the slip ring 43. The fixing spring 44 is installed inside the slide rod 33. An insert plate 46 is installed on the surface of the slip ring 43. An insert block 45 is installed at the bottom of the insert plate 46. The insert block 45 is inserted into the inside of several limiting blocks 42. The fixing spring 44 at the bottom of the slip ring 43 can achieve the effect of resetting after the slip ring 43 moves.

[0032] Finally, a crescent groove 310 is provided on the surface of the turntable 31, which allows the sliding rod 33 to slide laterally when the turntable 31 rotates. An arc-shaped groove 360 ​​is provided on the surface of the rotating shaft 36, which allows the sliding rod 37 to slide vertically when the rotating shaft 36 rotates. The cross-section of the insert block 45 is triangular, and the cross-section of the contact ring 38 is circular. The triangular cross-section of the insert block 45 facilitates insertion and engagement into the interior of the limiting ring 41.

[0033] In this embodiment, the fixing component 4 is used. The limiting ring 41 of the fixing component 4 is installed inside the sleeve 1. The limiting block 42 is a key locking structure. After the movable component 3 completes its contact with the sealing ring 2, the insert block 45 is inserted into the inner side of the limiting block 42 under the action of the sliding ring 43. The two engage and fix the relevant movable parts, restricting the rotation or movement of components such as the turntable 31, so that the contact block 35 and the contact ring 38 stably contact the sealing ring 2. If the contact state needs to be adjusted, such as for the repair of the sealing ring 2 or changes in the chassis structure, an external force is applied to the insert plate 46 to overcome the elasticity and pull it upward, causing the insert block 45 to disengage from the limiting block 42 and unlock. After adjustment, the insert plate 46 is released to reset the insert block 45 and lock it again, thus improving the sealing performance and stability of the connection between the sealing ring 2 and the sleeve 1.

[0034] In use, the automobile chassis rubber bushing of this utility model has a bushing body 1 as its basic structure and an internal sealing ring 2. The sealing ring 2 is abutted by a movable component 3 to achieve the corresponding function. A fixing component 4 restricts the movable component 3 after use, thus ensuring the stability of the entire bushing structure and the proper working condition of the sealing ring 2. A turntable 31 is rotatably connected inside the bushing body 1, and a control disc 32 at its bottom is also rotatably connected to the bottom of the bushing body 1. The two work together to rotate stably. When it is necessary to abut the sealing ring 2, the control disc 32 is rotated. When the control disc 32 rotates, it drives the turntable 31 to rotate. A sliding rod 33, slidably connected to the surface of the turntable 31, slides along the surface of the turntable 31. Since the outer side of the sliding rod 33 is hinged to the abutting rod 34, the sliding of the sliding rod 33 pushes the abutting rod 34 to move. The abutting block 35 mounted on the surface of the abutting rod 34 slides along the inside of the bushing body 1, and finally the abutting block 35 abuts against the sealing ring 2, applying force to the sealing ring 2 from the corresponding direction. The force ensures that the sealing ring 2 remains stable during the operation of the bushing and can better perform its sealing function. At the same time, the rotating shaft 36 installed inside the turntable 31 also participates in the operation. The sliding rod 37 slidably connected to the surface of the rotating shaft 36 will drive the abutment ring 38 on its surface to slide upward inside the sleeve 1 when the rotating shaft 36 rotates. When the abutment ring 38 slides upward, it will abut against the bottom of the sealing ring 2. The abutment ring 38 cooperates with the abutment block 35 to form a stable abutment effect on the sealing ring 2 from all directions, ensuring that the sealing ring 2 can fit tightly in the corresponding position and prevent it from shifting or loosening. It effectively prevents external dust, moisture, impurities and other substances from entering the bushing and avoids them from causing erosion, wear and other adverse effects on the internal structure of the bushing and the connection with the chassis. At the same time, it can also prevent the leakage of grease and other media used for lubrication and buffering inside the bushing, maintain a good sealing environment, ensure the sealing performance of the bushing, enable it to better perform its isolation and protection functions, maintain good sealing performance, and extend the service life of the bushing.

[0035] The limiting ring 41 of the fixed component 4 is installed inside the sleeve 1. Several limiting blocks 42 installed on its inner side are the key locking structure. After the movable component 3 completes its contact action against the sealing ring 2, the insert block 45 at the bottom of the insert plate 46 installed on the surface of the slip ring 43 will be driven by the slip ring 43 to insert into the inner side of the limiting block 42. The insert block 45 and the limiting block 42 interlock, fixing the position of the slide rod 33 and other related movable components, thereby restricting further rotation or movement of components such as the turntable 31 and the contact rod 34. This ensures that the contact block 35 and the contact ring 38 can continuously and stably maintain contact with the sealing ring 2, preventing accidental rotation or movement of the movable component 3 due to external vibrations, bumps during vehicle operation, etc., thus keeping the entire movable component 3 in a stable working state. If subsequent... The contact state of the movable component 3 with the sealing ring 2 needs to be adjusted. For example, if the sealing ring 2 needs to be replaced or repaired after long-term use, or if the contact force needs to be changed due to adjustments in the vehicle chassis structure, an external force can be applied to the insert plate 46 to overcome the elasticity of the fixed spring 44. This pulls the insert plate 46 upward, causing the insert block 45 to move upward and disengage from the limiting block 42. At this time, the movable components such as the turntable 31 are unlocked and can rotate and move freely. The movable component 3 can then be operated again to change the position and contact force of the contact block 35 and the contact ring 38. After the adjustment is completed, the insert plate 46 is released, and the slip ring 43 is reset under the action of the fixed spring 44, pushing the insert block 45 to re-insert into the limiting block 42 to achieve re-locking. This improves the sealing performance and stability of the connection between the sealing ring 2 and the sleeve 1.

[0036] The above embodiments are only used to illustrate the present utility model, and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
