Description

Technical Field

[0001] This utility model belongs to the field of automotive chassis suspension technology, specifically a disconnectable lateral stabilizer bar with a buffer structure. Background Technology

[0002] The stabilizer bar, also known as an anti-roll bar or balance bar, is an auxiliary elastic element in the car suspension. It is usually made of spring steel, has a "U" shape, and is placed horizontally at the front and rear of the car. The middle of the bar is hinged to the frame through a sleeve, and the two ends are fixed to the left and right suspensions respectively. Its main function is to prevent the car from rolling too much when turning, thereby improving driving stability.

[0003] In current technology, the stabilizer bar can be quickly connected and disconnected through a disconnectable mechanism.

[0004] However, when using existing devices, high lateral stiffness is required to suppress roll when the vehicle is turning at high speed on paved roads. But rigid stabilizer bars will directly transmit the vibration of the road surface on one side to the other side, resulting in increased bumpiness and reduced ride comfort. Therefore, a disconnectable lateral stabilizer bar with a buffer structure is proposed to address the above problems. Utility Model Content

[0007] Preferably, an auxiliary spring is fixedly connected to the first connecting plate, and the other end of the auxiliary spring is fixedly connected to the second connecting plate.

[0008] Preferably, a hydraulic buffer is fixedly connected to the first connecting plate, and the other end of the hydraulic buffer is fixedly connected to the second connecting plate.

[0013] The beneficial effects of this utility model are: 1. This utility model provides a disconnectable lateral stabilizer bar with a buffer structure. Through the triple buffer design of rubber buffer sleeve + alloy spring + hydraulic damper, it can absorb impacts of different amplitudes in stages, reduce vibration transmission and instantaneous load, reduce wear on stabilizer bar and suspension components, extend service life, eliminate abnormal noise, and provide driving comfort.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Specific implementation examples are given below.

[0019] Please see Figures 1-4 This utility model provides a detachable lateral stabilizer bar with a buffer structure, including a device body 10, on which a stabilizer bar body 11 is provided. A first connecting plate 21 is threaded to both ends of the stabilizer bar body 11, and a buffer sleeve 22 is fixedly connected to the first connecting plate 21. A second connecting plate 23 is fixedly connected to the other end of the buffer sleeve 22. A disconnecting mechanism 12 is fixedly connected to the outer surface of the second connecting plate 23. During operation, the stabilizer bar body 11 is integrally formed from high-strength alloy steel, and its two ends are machined with external threads for detachable connection with the first connecting plate 21. A buffer assembly is connected to the side of the first connecting plate 21 away from the stabilizer bar body 11 by welding or bolting. The buffer assembly is located away from the first connecting plate 21. One end of the connecting plate 21 is connected to a second connecting plate 23. A disconnecting mechanism 12 is fixedly connected to the outer surface of the second connecting plate 23. The disconnecting mechanism 12 can be connected to the lower control arm or steering knuckle of the vehicle suspension to realize the on-demand connection and disconnection of the stabilizer bar and the suspension system. The stabilizer bar body 11 is made of high-strength alloy steel, which provides lateral stiffness in the connected state, suppresses vehicle steering roll, and ensures handling. The first connecting plate 21 is a bridge connecting the stabilizer bar body 11 and the buffer assembly. It is detachably connected to the stabilizer bar by threads and provides a fixed support point for the buffer sleeve 22 and the auxiliary spring 24. The second connecting plate 23 is a transition piece connecting the buffer assembly and the disconnecting mechanism 12. It bears the force transmitted by the buffer assembly and provides an installation base for the disconnecting mechanism 12 to realize the orderly transmission of force.

[0020] Furthermore, such as Figure 4 As shown, an auxiliary spring 24 is fixedly connected to the first connecting plate 21, and the other end of the auxiliary spring 24 is fixedly connected to the second connecting plate 23. During operation, the auxiliary spring 24 is a secondary buffer component that withstands medium amplitude impacts, such as slight pits. It forms a rubber + spring double buffer with the buffer sleeve 22 to prevent vibration from being directly transmitted to the stabilizer bar.

[0021] Furthermore, such as Figure 4 As shown, a hydraulic buffer 25 is fixedly connected to the first connecting plate 21, and the other end of the hydraulic buffer 25 is fixedly connected to the second connecting plate 23. During operation, the hydraulic buffer 25 is a key high-level buffer located in the middle of the connecting plate. The hydraulic resistance is controlled by an adjustable valve to absorb large-amplitude impacts, such as when passing speed bumps or deep pits, and slowly release the impact energy to prevent damage to components due to instantaneous loads. The buffer strength can also be adjusted as needed.

[0022] Furthermore, such as Figure 4As shown, the hydraulic buffer 25 is located in the middle of the first connecting plate 21 and the second connecting plate 23. The hydraulic buffer 25 is equipped with a valve to adjust the resistance of the oil flow. When working, the hydraulic buffer 25 is filled with damping oil and is equipped with an adjustable valve. By controlling the resistance of the oil flow through the valve, the buffer strength can be adjusted according to the vehicle driving conditions.

[0023] Furthermore, such as Figure 4 As shown, the buffer sleeve 22 is a high-quality rubber bushing. The buffer sleeve 22 is fitted on the outside of the auxiliary spring 24. When working, the buffer sleeve 22 uses a high-quality rubber bushing to absorb the high-frequency small-amplitude vibration of the road surface, such as fine bumps, and reduce abnormal noise. At the same time, it is fitted on the outside of the auxiliary spring to play a protective role against dust and corrosion.

[0024] Furthermore, such as Figure 4 As shown, the auxiliary spring 24 is made of silicon manganese alloy spring steel. When working, the auxiliary spring 24 is made of silicon manganese alloy spring steel, which has the characteristics of high elastic limit and strong fatigue resistance. The two ends of the auxiliary spring 24 are respectively welded to the first connecting plate 21 and the second connecting plate 23. When in the natural state, it is in a slightly compressed state, which can withstand the impact load of medium amplitude and avoid the vibration being directly transmitted to the main body of the stabilizer bar 11.

[0025] Furthermore, such as Figure 1 and Figure 2 As shown, the disconnection mechanism 12 is an electro-hydraulic type, which controls the hydraulic piston through ECU signals to achieve disconnection and connection. During operation, the disconnection mechanism 12 is the core of function switching. The electro-hydraulic design controls the piston extension and retraction through ECU signals. When connected, it locks with the suspension, allowing the stabilizer bar to provide lateral stiffness and suppress roll. When disconnected, it separates from the suspension, allowing the left and right suspensions to move independently, without affecting the shock absorption effect of the buffer components.

[0026] Working Principle: The disconnecting mechanism 12 adopts an electro-hydraulic structure, the core of which includes a hydraulic cylinder, piston, electromagnetic control valve, and connecting joint. Automatic or manual control is achieved through the vehicle's electronic control unit (ECU). When the vehicle requires high lateral stiffness, such as during high-speed steering or emergency lane changes, the ECU sends a signal to the electromagnetic control valve, controlling hydraulic oil to enter the hydraulic cylinder, pushing the piston out and locking the connecting joint of the disconnecting mechanism 12 with the suspension components. The stabilizer bar body 11 is buffered by the buffer sleeve 22, auxiliary spring 24, and hydraulic damper 25. The disconnecting mechanism 12 forms a rigid connection with the suspension, effectively suppressing vehicle roll. When the vehicle is driving on unpaved roads, passing obstacles at low speeds, or when improved comfort is required, the EC... The U signal controls the hydraulic oil return, causing the piston to retract, separating the connecting joint from the suspension components, and disconnecting the stabilizer bar body 11 from the suspension. At this time, the left and right suspensions can move up and down independently to adapt to road undulations. Meanwhile, the buffer sleeve 22 and hydraulic damper 25 can still play a shock absorption role, preventing the suspension from directly impacting the vehicle body. The stabilizer bar body 11 is integrally formed from high-strength alloy steel, with external threads machined at both ends for detachable connection with the first connecting plate 21. A buffer assembly is connected to the side of the first connecting plate 21 away from the stabilizer bar body 11 by welding or bolting. The end of the buffer assembly away from the first connecting plate 21 is connected to the second connecting plate 23, and the outer surface of the second connecting plate 23 is fixedly connected to... A disconnect mechanism 12 is provided, which can be connected to the lower control arm or steering knuckle of the vehicle suspension to realize the on-demand connection and disconnection of the stabilizer bar and the suspension system. The stabilizer bar body 11 is made of high-strength alloy steel, which provides lateral stiffness in the connected state, suppresses vehicle body roll during steering, and ensures handling. The first connecting plate 21 is a bridge connecting the stabilizer bar body 11 and the buffer assembly. It is detachably connected to the stabilizer bar by threads and provides a fixing point for the buffer sleeve 22 and the auxiliary spring 24. The second connecting plate 23 is a transition piece connecting the buffer assembly and the disconnect mechanism 12. It bears the force transmitted by the buffer assembly and provides a mounting base for the disconnect mechanism 12 to realize the orderly transmission of force. The auxiliary spring 24 is a secondary buffer component. Withstanding moderate amplitude impacts, such as minor potholes, the buffer sleeve 22 forms a double buffer of rubber and spring, preventing vibration from being directly transmitted to the stabilizer bar. The hydraulic buffer 25 is a key advanced buffer, located in the middle of the connecting plate. It controls the oil resistance through an adjustable valve to absorb large amplitude impacts, such as speed bumps and deep potholes, and slowly releases the impact energy to prevent damage to components due to instantaneous loads. The buffer strength can also be adjusted as needed. The buffer sleeve 22 uses a high-quality rubber bushing to absorb high-frequency, low-amplitude vibrations from the road surface, such as minor bumps, reducing abnormal noises. At the same time, it is fitted on the outside of the auxiliary spring, providing dustproof and corrosion-proof protection. The auxiliary spring 24 is made of silicon-manganese alloy spring steel, which has the characteristics of high elastic limit and strong fatigue resistance.The auxiliary spring 24 is welded to the first connecting plate 21 and the second connecting plate 23 respectively. In its natural state, it is slightly compressed, capable of withstanding moderate amplitude impact loads and preventing vibration from being directly transmitted to the stabilizer bar body 11. The disconnect mechanism 12 is the core of the function switching, featuring an electro-hydraulic design. It controls the piston extension and retraction via ECU signals. When connected, it locks with the suspension, providing lateral stiffness to the stabilizer bar and suppressing roll; when disconnected, it separates from the suspension, allowing the left and right suspensions to move independently without affecting the shock absorption function of the buffer components.
