Description

Technical Field

[0001] The invention relates to the technical field of automobile stabilizer bars, and in particular to an anti-rollover type chassis stabilizer bar structure for a new energy heavy-duty truck. Background Art

[0002] The car chassis balance bar is installed under the car chassis. It is a balancing component used between the independent suspension structures of the left and right tires of the car. Its function is to connect the left and right tires in the same position of the car to prevent the car from tilting during driving due to different forces on the left and right tires when the car is turning and moving sideways, causing the safety hazard of the car tipping over. The use of the balance bar can pull back the independent suspension components and tires when the tires on both sides of the car tilt due to force, thereby maintaining the balance of the car.

[0003] The existing balance bar generally adopts an integrated structure setting and is equipped with a connecting rod assembly. The special-shaped balance rod and the connecting rod assembly cooperate with each other, wherein the two ends of the connecting rod are respectively connected to the special-shaped balance rod and the independent suspension mechanism, thereby achieving the effect of connection and positioning. However, in actual use, the application of the one-piece connected balance bar may also have some defects caused by balance problems. For example, when a vehicle is driving in a straight line and encounters a single-sided obstacle on the road such as a single-sided bridge, the tire and the independent suspension mechanism on one side are displaced and deformed by the force. Due to the connecting stabilizing effect of the balance bar, the balance bar will pull the independent suspension mechanism on the other side to deform, which also causes the buffering and energy release effect of the independent suspension mechanism on this side to be hindered, so that the unilateral buffering and shock-absorbing function of the tire is adversely affected, so that the overall shock-absorbing performance of the vehicle is low under special conditions when driving.

[0004] In view of the above problems, it is urgent to carry out innovative design based on the original automobile chassis stabilizer bar structure. Summary of the invention

[0005] The purpose of the present invention is to provide an anti-rollover type new energy heavy-duty truck chassis balance bar structure to solve the problem that the existing automobile chassis balance bar structure proposed in the above background technology has the function of traction to prevent rollover, but it will also affect the vehicle's buffering, energy release and shock absorption effect during normal driving, so that the overall shock absorption of the vehicle is adversely affected.

[0006] To achieve the above object, the present invention provides the following technical solutions: an anti-rollover type new energy heavy truck chassis balance bar structure, comprising a complete balance bar component composed of an intermediate bar and a side bar, wherein a connector is provided between the ends of the intermediate bar and the side bar; It also includes: a first spiral roller and a second spiral roller, which are respectively connected to the ends of the side rod and the middle rod located inside the connector, wherein a hydraulic wheel is rotatably provided at the connecting end of the second spiral roller and the middle rod, a limit piece is telescopically and movably installed in the middle of the hydraulic wheel, and the limit piece limits the rotation of the second spiral roller by hydraulic pressure, and a first liquid inlet and a second liquid inlet are provided at the positions of the hydraulic wheel and the limit piece on the outside of the connector corresponding to the positions.

[0007] Preferably, the positioner is rotatably connected to the side rod in a sleeve-like manner, and rubber sleeves are provided at the connection between the positioner and the middle rod and the side rod, and the upper end of the positioner is fixed to the chassis of the automobile.

[0008] Preferably, the transverse central axes of the side rod and the middle rod are arranged in parallel, wherein the side rod is "L"-shaped, and a connecting rod is hinged at the end of the side rod away from the middle rod.

[0009] Preferably, the side rod and the connector are rotatably mounted, and the middle rod and the connector are fixedly mounted, wherein the second spiral roller is rotatably connected to the middle rod, and the first spiral roller and the second spiral roller are meshingly mounted.

[0010] Preferably, the edges of the hydraulic wheel and the stopper are both arranged in an annular shape, and the annular outer wall is in close-fitting and sealed sliding connection with the inner wall of the connector through a sealing structure; At the same time, a liquid outlet is also connected through the outer wall of the connector below the hydraulic rotary wheel, and the middle chamber where the hydraulic rotary wheel is located is arranged corresponding to the liquid outlet and the first liquid inlet.

[0011] Preferably, the first spiral roller and the second spiral roller are both rotationally connected to the connector, and mutually meshing gears are sleeved between one end of the central axis of the first spiral roller and the second spiral roller located inside the connector, and the first spiral roller is fixed to the side rod.

[0012] Preferably, the limiter and the hydraulic wheel form a coaxial through-type axial relative telescopic structure, and the outer wall of the through-point between the limiter and the hydraulic wheel is set to be prismatic, while the limiter is engaged and positioned with the inner wall groove of the middle rod end.

[0013] Preferably, an elastic member is further provided at the extension point where the limiter and the hydraulic wheel penetrate, and the elastic member is used to control the resetting of the limiter, and a sealing cavity at the point where the limiter and the hydraulic wheel penetrate is provided corresponding to the second liquid inlet.

[0014] Preferably, a connecting valve is fixed on the middle outer wall of the intermediate rod through a positioner, and the connecting valve is connected to the liquid inlet of the first liquid inlet and the second liquid inlet.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: when the anti-rollover type new energy heavy-duty truck chassis balance bar structure encounters a unilateral obstacle during normal driving of the vehicle, the balance bar is disconnected, which will not affect the buffering energy release effect of the independent suspension, and has good stability in the docking state of the balance bar, further improving the buffering energy release and reset effect of the vehicle during driving. The specific contents are as follows: The first spiral roller and the second spiral roller mesh with each other to achieve the preliminary connection between the middle rod and the side rod, and the second spiral roller and the middle rod are maintained in a rigid connection state by hydraulic pressure. The first spiral roller and the second spiral roller are mutually limited, so that the middle rod, the side rod and the connector form an integrated arrangement with good rigidity and strength, so as to achieve the anti-roll effect of the balance bar on the vehicle during use; Furthermore, after the hydraulic restriction on the limiter is released, the limiter is no longer engaged with the intermediate rod, and the second spiral roller is now released from the restricted state and can rotate freely under the action of external force, thereby further releasing the restriction on the first spiral roller, so that the side rod can rotate and unload the force when the independent suspension structure deforms and releases energy under a unilateral obstacle caused by the vehicle, and the energy release effect of the independent suspension will not be affected by the traction of the rigid balance rod; Furthermore, the hydraulic wheel is installed correspondingly to the second spiral roller. When the second spiral roller is released from the limit and can rotate, the hydraulic action can be used to drive the second spiral roller to rotate in the opposite direction through the hydraulic wheel. Under the action of the second spiral roller and the gear structure thereon, the side rod can ensure the deformation buffering and energy release effect of the independent suspension structure under the rotation unloading force, assist the independent suspension structure to reset, and improve the buffering and shock absorption effect of the vehicle under continuous obstacles during driving.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions 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 creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-Figure 9 The present invention provides a technical solution: a chassis balance bar structure of an anti-rollover new energy heavy-duty truck, comprising a complete balance bar component composed of an intermediate bar 1 and a side bar 2, wherein a connector 4 is arranged between the ends of the intermediate bar 1 and the side bar 2; the transverse central axes of the side bar 2 and the intermediate bar 1 are arranged in parallel, wherein the side bar 2 is "L"-shaped, and the end of the side bar 2 away from the intermediate bar 1 is hinged with a connecting rod; the side bar 2 and the positioner 3 are sleeved and rotatably connected, and a rubber sleeve is arranged at the connection between the positioner 3 and the intermediate bar 1 and the side bar 2, and the upper end of the positioner 3 is fixed to the chassis of the automobile; the intermediate bar 1 and the side bar 2 form a complete balance bar component, the two are connected and positioned by a connector 4, and under the action of the connecting rod, they are connected to the independent suspension mechanism on the vehicle, so as to achieve the effect of balanced traction and preventing the vehicle from rolling.

[0020] Among them, this technical structure needs to be used in combination with electrical components such as the existing automobile laser radar or visual detection technology. During the movement of the vehicle, the roadside conditions are continuously detected, so that the use of the connecting valve 12 is controlled by the assembly and setting of the electrical components, and the hydraulic pressurizing component is selectively used to selectively introduce the pressurized liquid through the first liquid inlet 9 and the second liquid inlet 10, and the rigid connection or movable connection between the middle rod 1 and the side rod 2 is controlled by hydraulic action. Further as follows: a connecting valve 12 is fixed on the middle outer wall of the middle rod 1 through a positioner 3, and the connecting valve 12 is connected to the first liquid inlet 9 and the second liquid inlet 10.

[0021] Furthermore, in the present technical solution, the first spiral roller 5 and the second spiral roller 6 are respectively connected to the ends of the side rod 2 and the middle rod 1 located inside the connector 4, wherein a hydraulic rotary wheel 7 is rotatably provided at the connection end between the second spiral roller 6 and the middle rod 1, and a limit member 8 is telescopically and movably installed in the middle of the hydraulic rotary wheel 7, and the limit member 8 limits the rotation of the second spiral roller 6 by hydraulic pressure, and at the same time, a first liquid inlet 9 and a second liquid inlet 10 are provided at the positions of the hydraulic rotary wheel 7 and the limit member 8 on the outer side of the connector 4; the limit member 8 and the hydraulic rotary wheel 7 form a coaxial through-type axial relative telescopic structure, and the outer wall of the through-point of the limit member 8 and the hydraulic rotary wheel 7 is set to be prismatic, and at the same time, the limit member 8 is engaged with the inner wall groove of the end of the middle rod 1 for positioning; an elastic member is also provided at the through-telescopic point of the limit member 8 and the hydraulic rotary wheel 7, and the elastic member is used to control the reset of the limit member 8, and a sealed cavity at the through-point of the limit member 8 and the hydraulic rotary wheel 7 is set corresponding to the second liquid inlet 10 When the vehicle encounters a unilateral obstacle such as a unilateral bridge during driving, one tire of the vehicle continues to drive on the obstacle. At this time, under the action of the hydraulic pressure component and the connecting valve 12, the hydraulic state corresponding to the second liquid inlet 10 is released, and under the action of the elastic member, the oil inside the sealed cavity where the limit member 8 and the hydraulic wheel 7 pass through is discharged in the opposite direction. The oil pressure relief makes the limit member 8 no longer engage and position with the inner wall groove at the end of the intermediate rod 1. At this time, the second spiral roller 6 is released from the limiting state and can rotate freely. When the tire and its corresponding independent suspension structure undergo reciprocating lifting and lowering movements due to driving obstacles, the independent suspension structure drives the side rod 2 to move through the connecting rod, and the side rod 2 rotates relative to the connector 4, which will not affect the intermediate rod 1, nor will it apply traction to the side rod 2 on the other side through the intermediate rod 1, so that the side rod 2 and the corresponding independent suspension structure can perform good buffering and energy release, thereby improving the buffering and energy release effect of the independent suspension.

[0022] Furthermore, in the above technical scheme, the side rod 2 and the connector 4 are rotatably installed, and the middle rod 1 and the connector 4 are fixedly installed, wherein the second spiral roller 6 is rotatably connected to the middle rod 1, and the first spiral roller 5 and the second spiral roller 6 are meshingly installed; the edges of the hydraulic rotary wheel 7 and the limiter 8 are both arranged in a ring shape, and the outer wall of the ring is in a sliding connection with the inner wall of the connector 4 through a sealing structure to form a close-fitting seal; at the same time, a liquid outlet 11 is also connected through the outer wall of the connector 4 below the hydraulic rotary wheel 7, and the middle chamber where the hydraulic rotary wheel 7 is located is arranged corresponding to the liquid outlet 11 and the first liquid inlet 9; the first spiral roller 5 and the second spiral roller 6 are both rotatably connected to the connector 4, and the first spiral roller 5 and the second spiral roller 6 are located on the central axis inside the connector 4. Gears meshing with each other are sleeved between the one end and the other end, and the first spiral roller 5 is fixed to the side rod 2; when the independent suspension structure reciprocates to release energy due to buffering due to the continuous encounter of the vehicle with obstacles, the reset state of its energy release is achieved by controlling the use of the connecting valve 12, so that the oil is pressurized and introduced into the first liquid inlet 9 and discharged from the liquid outlet 11. In this process, the oil gives driving kinetic energy to the hydraulic wheel 7, so that the hydraulic wheel 7 and the second spiral roller 6 rotate in the opposite direction. Under the action of the second spiral roller 6 and the gear structure installed thereon, the first spiral roller 5 and its corresponding side rod 2 are driven in the opposite direction to perform movement reset, so that the side rod 2 can be quickly reset with its corresponding independent suspension system, so that the effect of buffering energy release during work is better, and the vibration and driving safety of the vehicle during driving are reduced.

[0023] Furthermore, in the present technical solution, when the vehicle is traveling on a curved and turning road, it is detected by a combination of electrical components such as a laser radar or visual detection technology, and the oil is introduced into the second liquid inlet 10 through the valve 11. The oil pressure of the oil causes the limiter 8 and the hydraulic wheel 7 to move axially outward, and the raised structure at the end of the limiter 8 is engaged with the inner wall groove at the end of the intermediate rod 1 for positioning. At this time, the limiting effect of the second spiral roller 6 is achieved through the intermediate rod 1, the limiting member 8 and the hydraulic wheel 7, and the limiting meshing performance of the second spiral roller 6 and the first spiral roller 5 is utilized. The side rod 2 is synchronously limited to form an integral fixed structure with the connector 4 and the middle rod 1, which has a good stabilizing effect and prevents the vehicle from tipping over during driving; further, a solid lubricating substance can be arranged in the internal cavity of the connector 4 to prevent the damping engagement when the first spiral roller 5 can rotate freely, and at the same time, the connection state between the second spiral roller 6 and the first spiral roller 5, when the side rod 2 and the middle rod 1 are used synchronously to prevent the vehicle from tipping over, the second spiral roller 6 and the first spiral roller 5 are firmly connected and will not break or be damaged due to shear and torsion external forces.

[0024] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
