Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts, and in particular relates to an automobile, a stabilizer bar connecting rod and a method for adjusting the length of the stabilizer bar connecting rod. Background Art

[0002] In order to improve the stability of the vehicle while driving, most modern cars use a lateral stabilizer bar device. Generally, the two ends of the lateral stabilizer bar are connected to the steering knuckle or shock absorber bracket through a stabilizer bar connecting rod, so that the vehicle can generate a larger roll angle stiffness when it rolls, thereby resisting the vehicle's roll and improving vehicle stability.

[0003] Under the premise that the direction and hard points of the stabilizer bar are determined and firmly fixed, the effect of the lateral stabilizer bar on vehicle handling and comfort can be dynamically adjusted by adjusting the length of the stabilizer bar connecting rod. For example, in off-road conditions, in order to maximize the suspension travel and keep the wheels in contact with the ground as much as possible, the stabilizer bar connecting rod needs to be disconnected or its length can be freely adjusted.

[0004] For example, in a roll condition, when the torsional stiffness between the stabilizer bar bushing and the lateral stabilizer bar is large (the lateral stabilizer bar will not rotate in the bushing), increasing the length of the outer stabilizer bar connecting rod and reducing the length of the inner stabilizer bar connecting rod can improve the vehicle's roll angle to a certain extent;

[0005] For example, on damaged or bumpy roads, disconnecting the stabilizer bar connecting rod or making the stabilizer bar connecting rod length adjustable can greatly reduce the impact of the lateral stabilizer bar on vehicle comfort.

[0006] To enhance handling and comfort, some high-end vehicles on the market currently utilize electronically controlled stabilizer bars. These bars incorporate a hydraulic and electronic control system based on conventional lateral stabilizer bars. When the vehicle is traveling in a straight line, the center cross control disconnects the stabilizer bar, significantly improving driving comfort. However, due to their high cost and large motor size, electronically controlled stabilizer bars are generally only used on ultra-high-end vehicles and are difficult to apply to standard models.

[0007] However, existing stabilizer bar connecting rods cannot achieve automatic length adjustment, thus failing to achieve dynamic adjustment of the vehicle's handling and comfort performance by the lateral stabilizer bar. Therefore, providing a stabilizer bar connecting rod that can automatically adjust its length is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0008] In response to the above problems, the present invention proposes a stabilizer bar connecting rod to solve the technical problem that the stabilizer bar connecting rods in the prior art cannot achieve automatic length adjustment, thereby failing to achieve dynamic adjustment of the vehicle handling and comfort performance of the lateral stabilizer bar.

[0045] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0046] Example 1:

[0047] A stabilizer bar connecting rod comprises an intermediate shaft 1 and two sets of sliding shafts 2; wherein,

[0048] The intermediate shaft 1 is a tubular structure with both ends open. Figure 3 and Figure 4 , an adjustment system 3 is provided on the intermediate shaft 1;

[0049] Two sets of sliding shafts 2 are respectively slidably arranged at both ends of the intermediate shaft 1 along the axis of the intermediate shaft 1, see Figure 1 and Figure 2 The distance between the movable ends of the two sets of sliding shafts 2 (the ends of the sliding shafts 2 away from the intermediate shaft 1) is automatically adjusted by the adjustment system 3 to achieve free adjustment of the length of the stabilizer bar connecting rod.

[0050] Optimally, the movable end of the sliding shaft 2 is provided with a ball head 22 or a bushing, and the movable ends of the two sets of sliding shafts 2 are respectively connected and fixed to the shock absorber and the car's transverse stabilizer bar 4 through the ball head 22 or the bushing, so that the stabilizer bar connecting rod can be firmly installed on the car.

[0051] This embodiment is described by taking the movable end of the sliding shaft 2 as an example. The ball head 22 includes a ball pin, a ball pin seat and a ball pin cover. Figure 2 ;in,

[0052] The ball pin seat is fixed on the sliding shaft 2 through a threaded connection, the ball pin is set on the ball pin seat, the ball pin cover is sleeved on the ball pin seat, and the ball pin is clamped on the ball pin seat to prevent the ball pin from falling off the ball pin seat.

[0053] Preferably, the stabilizer bar connecting rod further comprises a locking nut, and the ball pin seat is locked and fixed on the sliding shaft 2 by the locking nut, so that the connection between the ball pin seat and the sliding shaft 2 is more stable, thereby improving the safety of the stabilizer bar connecting rod when in use.

[0054] It should be noted that the structure of the ball head 22 is exactly the same as the structure of the ball head 22 of the stabilizer bar connecting rod on the vehicle in the prior art, and will not be described in detail here.

[0055] Optimally, the above-mentioned adjustment system 3 includes a suspension controller 33 and an electromagnetic coil 32; wherein,

[0056] The electromagnetic coil 32 is wrapped around the intermediate shaft 1;

[0057] The sliding end of the sliding shaft 2 (the end away from the ball head 22 or the bushing, i.e., the end slidingly arranged inside the intermediate shaft 1) is provided with a magnetic element 21. The magnetic poles of the magnetic elements 21 provided on the two sets of sliding shafts 2 are opposite, and are opposite to the magnetic poles of the electromagnetic coil 32 on the intermediate shaft 1 when energized.

[0058] When the electromagnetic coil 32 is energized, the intermediate shaft 1 will form an internal hollow electromagnet structure. By adjusting the magnetic force of the intermediate shaft 1, the relative distance between the two sets of sliding shafts 2, that is, the distance between the movable ends of the two sets of sliding shafts 2, can be adjusted, thereby achieving the adjustment of the length of the stabilizer bar connecting rod.

[0059] In order to better understand that the magnetic poles of the opposite surfaces of the magnetic elements 21 provided on the two sets of sliding shafts 2 are opposite, and are opposite to the magnetic poles of the electromagnetic coil 32 on the intermediate shaft 1 after being energized, the following example is used to illustrate:

[0060] The two sets of sliding shafts 2 are respectively the first sliding shaft and the second sliding shaft. The magnetic pole of the magnetic element 21 on the first sliding shaft facing away from the first sliding shaft is N-pole, and the magnetic pole of the magnetic element 21 on the second sliding shaft facing away from the second sliding shaft is S-pole. When the electromagnetic coil 32 on the intermediate shaft 1 is energized, the magnetic pole on the side mating with the first sliding shaft is S-pole, and the magnetic pole on the side mating with the second sliding shaft is N-pole.

[0061] When the resistance in the adjustment system 3 is the largest and the current is the smallest, the magnetic field intensity generated when the electromagnetic coil 32 is energized is the weakest, and the effect on the magnetic elements 21 on the first and second sliding shafts is minimal. At this time, the magnetic elements 21 on the first and second sliding shafts will overcome the tiny thrust provided by the electromagnetic coil 32 (the thrust between the electromagnet and the magnetic element 21) and attract each other, minimizing the relative distance between the first and second sliding shafts and shortening the length of the stabilizing bar connecting rod to its shortest length.

[0062] When the resistance in the adjustment system 3 is the smallest and the current is the largest, the magnetic field intensity generated when the electromagnetic coil 32 is energized is the strongest, and the impact on the magnetic elements 21 on the first sliding shaft and the second sliding shaft is the greatest. At this time, the magnetic elements 21 on the first sliding shaft and the second sliding shaft will move away from each other under the action of the thrust provided by the electromagnetic coil 32, so that the relative distance between the first sliding shaft and the second sliding shaft is the largest, and the length of the stabilizing rod connecting rod is extended to the longest.

[0063] Optimized, the above-mentioned adjustment system 3 includes a variable resistor 31, and the suspension controller 33 is electrically connected to the electromagnetic coil 32 through the variable resistor 31. The suspension controller 33 can change the current size of the electromagnetic coil 32 by changing the size of the resistance in the variable resistor 31, so as to achieve a change in the magnetic field strength of the intermediate shaft 1, thereby achieving adjustment of the length of the stabilizer bar connecting rod.

[0064] It should be noted that the circuit of the electromagnetic coil 32 is a normally closed circuit. By adjusting the resistance of the variable resistor 31 in the normally closed circuit, the current in the normally closed circuit can be changed, thereby changing the magnetic field strength.

[0065] At the same time, matching of different vehicles and stabilizer bar connecting rods can be achieved by matching the voltage of different normally closed circuits, the density of the electromagnetic coil 32, the size of the variable resistor 31, the length of the sliding shaft 2, the magnetic size of the magnetic element 21, and other solutions.

[0066] Preferably, the shape of the above-mentioned magnetic element 21 matches the cross-sectional shape of the inner cavity of the intermediate shaft 1, and the circumferential side wall of the magnetic element 21 is provided with a wear-resistant layer, which also has the characteristic of high temperature resistance and can effectively prevent the magnetic element 21 from sliding and wearing in the intermediate shaft 1.

[0067] It should be noted that the magnetic element 21 may be ferrite, samarium cobalt magnet, alnico magnet, neodymium iron boron magnet (rare earth permanent magnet material) or composite permanent magnet material, etc.

[0068] The wear-resistant layer is made of materials such as polyetherketone (PEEK), polytetrafluoroethylene (PTFE) or polyphenylene ether (PPE).

[0069] Preferably, the cross-section of the inner cavity of the intermediate shaft 1 is circular, and the cross-section of the magnetic element 21 is circular to match the cross-section of the inner cavity of the intermediate shaft 1 .

[0070] Optimized, the stabilizer bar connecting rod also includes an active detection system 6, the active detection system 6 is connected to the suspension controller 33 via sensor signals, see Figure 5 ;in,

[0071] The signal connection between the active detection system 6 and the suspension controller 33 refers to a wireless connection, for example, Bluetooth, wireless or WIFI and other wireless connection technologies commonly used in the prior art.

[0072] Specifically, the active detection system 6 includes a camera, a gyroscope and / or a vibration acceleration sensor; wherein,

[0073] The camera, gyroscope and / or vibration acceleration sensor can monitor road conditions and / or vehicle posture information and feed this information back to the suspension controller 33. The suspension controller 33 then controls the magnitude of the current flowing into the electromagnetic coil 32 to adjust the length of the stabilizer bar connecting rod.

[0074] If the camera detects a damaged road ahead, it will send the collected information to the suspension controller 33. The suspension controller 33 will reduce the current in the electromagnetic coils 32 in the left and right stabilizer bar connecting rods of the vehicle, so that the force exerted by the magnetic field on the two sets of sliding shafts 2 is reduced, thereby reducing the impact of the stabilizer bar connecting rods on vehicle comfort.

[0075] For example, when the vehicle's gyroscope detects the body roll angle or roll acceleration, the gyroscope will send the collected information to the suspension controller 33, and the suspension controller 33 will control the magnitude of the current passed into the electromagnetic coil 32, so that the length of the stabilizer bar connecting rod on the inner side of the vehicle (inside of the curve) is reduced, and the length of the stabilizer bar connecting rod on the outer side of the vehicle (outside of the curve) is increased, thereby improving the vehicle's roll angle to a certain extent, thereby suppressing the vehicle's roll.

[0076] Optimally, the intermediate shaft 1 is provided with a cooling system 11, see Figure 4 ;in,

[0077] The cooling system 11 includes a cooling water channel, which is arranged in the tube wall of the intermediate shaft 1 and surrounds the circumference of the intermediate shaft 1;

[0078] The cooling system 11 can reduce the problem of heat generation of the electromagnetic coil 32 during operation and reduction of magnetic field strength, thereby ensuring the operational stability of the stabilizer bar connecting rod.

[0079] It should be noted that the cooling water channel may be a closed water channel, the liquid inside of which may absorb the heat generated by the electromagnetic coil 32 during operation and quickly dissipate it into the air to achieve a cooling effect;

[0080] Of course, the above-mentioned cooling water circuit can also be a circulating water circuit. For example, it can be connected in series with the cooling system 11 in the automobile engine. The coolant in the automobile can first pass through the cooling water circuit of the stabilizer bar connecting rod to cool it down, and then enter the engine cooling system to cool the engine. Then, it is circulated after heat dissipation through the engine cooling system (radiator) to reduce the problem of heat generation of the electromagnetic coil 32 during operation and reduction of the magnetic field strength.

[0081] Preferably, the intermediate shaft 1 is made of a material (such as copper or aluminum) with good electromagnetic radiation protection, thermal conductivity, and reflectivity, so as to isolate the magnetic field and avoid the problem of magnetic field intensity radiation.

[0082] Optimally, both ends of the intermediate shaft 1 are provided with limit covers 12, see Figure 3 and Figure 4 The limiting cover 12 can effectively prevent the sliding shaft 2 from being separated from the intermediate shaft 1, so as to ensure the safety of the stabilizer bar connecting rod.

[0083] Specifically, the above-mentioned limit cover 12 is an annular plate structure. The inner diameter of the limit cover 12 matches the diameter of the sliding shaft 2. The diameter of the above-mentioned magnetic element 21 is larger than the inner diameter of the limit cover 12. The limit cover 12 is coaxially arranged at the end of the intermediate shaft 1. The sliding end of the sliding shaft 2 is slidably arranged in the intermediate shaft 1. The movable end of the sliding shaft 2 passes through the limit cover 12 and extends in a direction away from the center of the intermediate shaft 1.

[0084] The limiting cover 12 can effectively prevent the sliding end of the sliding shaft 2 from escaping from the intermediate shaft 1, so that the structure of the stabilizer bar connecting rod is more stable and safer when in use.

[0085] Preferably, a buffer pad 121 is provided on the side of the limit cover 12 facing the center of the intermediate shaft 1, see Figure 4 The buffer pad 121 can prevent direct collision between the magnetic element 21 and the limiting cover 12 when the sliding shaft 2 slides in the intermediate shaft 1, thereby preventing the stabilizer bar connecting rod from making abnormal noise or damaging the magnetic element 21 during use.

[0086] Based on the stabilizer bar connecting rod, the present invention also provides a car, which includes a car body and the stabilizer bar connecting rod, see Figure 6 ;in,

[0087] The movable ends of the two sets of sliding shafts 2 in the stabilizer bar connecting rod are respectively connected to the lateral stabilizer bar 4 and shock absorber 5, control arm or steering knuckle of the vehicle body. In this embodiment, the movable ends of the two sets of sliding shafts 2 in the stabilizer bar connecting rod are respectively connected to the lateral stabilizer bar 4 and shock absorber 5 of the vehicle body, and the adjustment system 3 in the stabilizer bar connecting rod is connected to the active detection system 6 of the vehicle body by signal.

[0088] The stabilizer bar connecting rod in the car adjusts the distance between the movable ends of the two sets of sliding shafts 2 through the adjustment system 3 to adjust the length of the stabilizer bar connecting rod, thereby achieving dynamic adjustment of the influence of the stabilizer bar connecting rod on the vehicle comfort and handling performance;

[0089] Furthermore, the stabilizer bar connecting rod is highly platform-based and universal, and can be combined with the vehicle's active detection system 6 to achieve active adjustment of suspension comfort and handling performance.

[0090] Example 2:

[0091] A method for adjusting the length of a stabilizer bar connecting rod, the method is performed by the vehicle described in the first embodiment, see Figure 7 , the method comprises the following steps:

[0092] The active detection system 6 feeds back the monitored road conditions and / or vehicle posture information to the adjustment system 3, which adjusts the spacing between the movable ends of the two sets of sliding shafts 2 through the adjustment system 3 to achieve dynamic adjustment of the impact of the stabilizer bar connecting rod on vehicle comfort and handling performance.

[0093] For example, during a turn, the vehicle's gyroscope detects the body roll angle or roll acceleration, and the gyroscope sends the collected information to the suspension controller 33. The suspension controller 33 adjusts the variable resistor 31 to control the magnitude of the current flowing into the electromagnetic coil 32, thereby reducing the length of the stabilizer bar connecting rod on the inner side of the vehicle (inside the curve) and increasing the length of the stabilizer bar connecting rod on the outer side of the vehicle (outside the curve), thereby improving the vehicle's roll angle to a certain extent. At this time, if the vehicle's gyroscope feeds back that the vehicle is in a stable state, the suspension controller 33 controls the variable resistor 31 to continue to maintain this state (stationary). If the vehicle's gyroscope feeds back that the vehicle is still in a body roll angle or roll acceleration state, the suspension controller 33 continues to adjust the variable resistor 31 until the vehicle's gyroscope feeds back that the vehicle is in a stable state.
