Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to an all-terrain vehicle. Background Art

[0002] The stabilizer bar of an all-terrain vehicle, also known as an anti-roll bar, can prevent the body of the all-terrain vehicle from rolling over due to excessive roll during turning, thereby improving the driving smoothness.

[0003] However, in the prior art, the stabilizer bar has a complex structure, high precision requirements, and a large number of parts. The stiffness value of the stabilizer bar is fixed and cannot be adaptively adjusted according to different vehicle conditions and driving conditions during driving. For example, when the all-terrain vehicle is turning or driving on an uneven road surface, it cannot be adaptively adjusted according to different road conditions, resulting in poor experience in terms of controllability and comfort. Summary of the Invention

[0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide an all-terrain vehicle with a stabilizer bar assembly having strong adaptability.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] An all-terrain vehicle, comprising: a frame; a traveling assembly, the traveling assembly including front wheels and rear wheels at least partially disposed under the frame; an electrical assembly, the electrical assembly at least partially disposed on the frame; a suspension mechanism, the suspension mechanism connecting the front wheels and the rear wheels to the frame, the suspension mechanism including a stabilizer bar assembly, the stabilizer bar assembly disposed between two front wheels and / or two rear wheels; wherein, the stabilizer bar assembly includes a left torsion bar, a right torsion bar and an oil circuit for balancing the all-terrain vehicle, the left torsion bar and the right torsion bar can be driven by the oil in the oil circuit to enter a connected state or a relative movement state, and the stabilizer bar assembly includes an active mode and a passive mode; when the stabilizer bar assembly enters the active mode, the left torsion bar and the right torsion bar can switch between the connected state and the relative movement state according to the road conditions; the passive mode includes a disconnection mode and a locking mode, when the stabilizer bar assembly enters the disconnection mode, the left torsion bar and the right torsion bar are in a relative movement state, and when the stabilizer bar assembly enters the locking mode, the left torsion bar and the right torsion bar are in a connected state.

[0007] Further, the oil circuit includes a connected state and a disconnected state. When the stabilizer bar assembly enters the active mode, the oil circuit switches between the connected state and the disconnected state, and the left torsion bar and the right torsion bar switch between the connected state and the relative movement state; when the stabilizer bar assembly enters the disconnection mode, the oil circuit is in the connected state, and the left torsion bar and the right torsion bar are in the connected state; when the stabilizer bar assembly enters the locking mode, the oil circuit is in the disconnected state, and the left torsion bar and the right torsion bar are in a relative movement state.

[0008] Further, the electrical component includes an operating member, a detecting member, and a control module. The operating member and the detecting member are electrically connected to the control module. The driver can switch different modes of the stabilizer bar assembly by operating the operating member. The control module is connected to the stabilizer bar assembly. When the stabilizer bar assembly enters the active mode and the detecting member detects that the all-terrain vehicle is away from the preset road condition (the preset road condition refers to a road condition with alternating flat and rough sections), the control module controls the left torsion bar and the right torsion bar to be in a connected state. When the detecting member detects that the all-terrain vehicle is approaching or passing through the preset road condition, the control module controls the left torsion bar and the right torsion bar to be in a relatively moving state.

[0009] Further, the stabilizer bar assembly further includes a housing. An accommodating space is formed by surrounding the housing. The accommodating space includes a first liquid chamber and a second liquid chamber. At least part of the left torsion bar and the right torsion bar are disposed in the first liquid chamber. When the oil circuit is in a connected state, the first liquid chamber and the second liquid chamber are in communication. When the oil circuit is in a disconnected state, the first liquid chamber and the second liquid chamber are separated.

[0010] Further, the stabilizer bar assembly further includes a piston and a control valve. The electrical component further includes a driving member for driving the piston to move. The driving member is used to drive the piston to push the hydraulic fluid to move in the oil circuit. The control valve is used to control whether the current oil circuit is connected so that the hydraulic fluid enters different oil circuits. The control valve includes a first control valve and a second control valve. When both the first control valve and the second control valve are open, the oil circuit is in... When both the first control valve and the second control valve are closed, the oil circuit is in a disconnected state.

[0011] Further, the oil circuit further includes a preparation state and a recovery state. When the stabilizer bar assembly enters the active mode and the all-terrain vehicle is about to move away from the preset road condition, the oil circuit is in the preparation state. The first control valve is open and the second control valve is closed. After the all-terrain vehicle moves away from the preset road condition, the oil circuit is in the recovery state. The first control valve is closed and the second control valve is open. The left torsion bar and the right torsion bar are switched from the relatively moving state to the connected state.

[0012] Further, the piston is connected to the driving member. The piston includes a first position and a second position. When the all-terrain vehicle is about to move away from the preset road condition, the driving member drives the piston to move from the second position to the first position, so that the hydraulic fluid is transported from the second liquid chamber to the first liquid chamber. When the all-terrain vehicle moves away from the preset road condition, the driving member drives the piston to move from the first position to the second position.

[0013] Further, the stabilizer bar assembly further includes a transmission member. One end of the transmission member is connected to the driving member and the other end is connected to the piston.

[0014] Further, the stabilizer bar assembly further includes a seal and a seal groove. At least part of the seal is disposed in the seal groove. The seal is sleeved on the piston.

[0015] Further, the piston includes a first piston and a second piston. The transmission member is drivingly connected to the first piston, and the second piston drives the first piston to perform a reciprocating linear motion.

[0016] For the balance assembly provided by the above all-terrain vehicle, by connecting or disconnecting the left torsion bar and the right torsion bar, the balance assembly can adjust different modes to adapt to different road conditions. The stabilizer bar assembly has strong adaptability, thus meeting the adaptability of the all-terrain vehicle to different road conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the specific 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.

[0025] As shown in Figure 1 and Figure 2As shown, an all-terrain vehicle 100 includes a frame 11, a traveling assembly 12, an electrical assembly 13, and a suspension mechanism 14. The frame 11 constitutes the overall framework of the all-terrain vehicle 100. The traveling assembly 12 includes a front wheel 122 and a rear wheel 121, and the front wheel 122 and the rear wheel 121 are at least partially disposed on the frame 11. The electrical assembly 13 is at least partially disposed on the frame 11. The suspension mechanism 14 includes a stabilizer bar assembly 141. The stabilizer bar assembly 141 is disposed on two front wheels 122 and / or two rear wheels 121. The suspension mechanism 14 is at least partially disposed on the frame 11. The stabilizer bar assembly 141 adapts to different road conditions to improve the stability of the all-terrain vehicle 100. To clearly illustrate the technical solution of the present invention, the left, right, front, rear, up, and down as shown in Figure 1 are also defined.

[0026] Such as Figure 2 or Figure 3As shown, the stabilizer bar assembly 141 includes a left torsion bar 1411, a right torsion bar 1412, and an oil passage 1414. The left torsion bar 1411 and the right torsion bar 1412 are connected or separated, and at least a part of the left torsion bar 1411 and the right torsion bar 1412 is disposed within the oil passage 1414. The stabilizer bar assembly 14 includes an active mode and a passive mode. The passive mode includes a locked mode and a disconnected mode. Among them, the locked mode means that the left torsion bar 1411 and the right torsion bar 1412 are in a connected state; the disconnected mode means that the left torsion bar 1411 and the right torsion bar 1412 are in a relative movement state; the active mode means that the left torsion bar 1411 and the right torsion bar 1412 can be switched between the connected state and the relative movement state. The oil passage 1414 includes a connected state and a disconnected state. The electrical assembly 13 includes an operating member 131. The operating member 131 is used to switch different modes of the left torsion bar 1411 and the right torsion bar 1412. When the all-terrain vehicle 100 passes through a first preset road condition, the operator operates the operating member 131 so that the operating member 131 controls the left torsion bar 1411 and the right torsion bar 1412 to be in the active mode, thereby causing the oil passage 1414 to switch between the connected state and the disconnected state; when the all-terrain vehicle 100 passes through a second preset road condition, the operator operates the operating member 131 so that the operating member 131 controls the left torsion bar 1411 and the right torsion bar 1412 to be disconnected, and the stabilizer bar assembly 14 is in the disconnected mode; when the all-terrain vehicle 100 passes through a third preset road condition, the operator operates the operating member 131, and the operating member 131 controls the left torsion bar 1411 and the right torsion bar 1412 to be connected so that the stabilizer bar assembly 14 is in the locked mode. Through the above settings, the operator can operate the operating member 131 according to the actual road condition to switch the mode of the stabilizer bar assembly 141. The stabilizer bar assembly 141 has strong adaptability, thereby improving the adaptability of the all-terrain vehicle 100 to the actual road condition to meet the comfort of the operator when operating the all-terrain vehicle 100. It should be noted that the first preset road condition refers to a road condition with alternating flat and rough sections, such as an urban road condition; the second preset road condition refers to a rough road condition; the third preset road condition refers to a flat road condition; the connected state of the oil passage 1414 means a state in which the oil can be transported in the oil passage 1414; the disconnected state of the oil passage 1414 means a state in which the oil cannot be transported in the oil passage 1414.

[0027] As Figure 2 and Figure 3As shown, as an implementation, the electrical component 13 includes a control module 132 and a detector 133. When the left torsion bar 1411 and the right torsion bar 1412 are in the active mode, the detector 133 is configured to transmit the road surface data of the all-terrain vehicle 100 to the control module 132, and the control module 132 is configured to control the connection or disconnection of the left torsion bar 1411 and the right torsion bar 1412. When the detector 133 detects that the all-terrain vehicle 100 is away from the first preset road condition, the detector 133 transmits a data signal to the control module 132, and the control module 132 controls the connection of the left torsion bar 1411 and the right torsion bar 1412. At this time, the oil circuit 1414 is in the disconnected state; when the detector 133 detects that the all-terrain vehicle 100 is approaching the first preset road condition, the detector 133 transmits a data signal to the control module 132, and the left torsion bar 1411 and the right torsion bar 1412 are disconnected. At this time, the oil circuit 1414 is in the connected state; when the all-terrain vehicle 100 passes through the first preset road condition, the detector 133 transmits a data signal to the control module 132, and the left torsion bar 1411 and the right torsion bar 1412 are separated. At this time, the oil circuit 1414 is in the connected state. Through the above settings, when the all-terrain vehicle 100 is approaching or passing through the first preset road condition, the control module 132 controls the left torsion bar 1411 and the right torsion bar 1412 to be in a relative movement state, so that the left torsion bar 1411 and the right torsion bar 1412 can perform relative displacement according to the road condition, so that when the all-terrain vehicle 100 passes through the first preset road condition, the left torsion bar 1411 and the right torsion bar 1412 can be adjusted according to different road conditions, thereby improving the adaptability of the all-terrain vehicle 100 to different road conditions. When the all-terrain vehicle 100 is away from the first preset road condition, the control module 132 controls the connection of the left torsion bar 1411 and the right torsion bar 1412, thereby improving the connection stability of the left torsion bar 1411 and the right torsion bar 1412, and further improving the driving stability of the all-terrain vehicle 100.

[0028] As an implementation, the detection component 133 and the control module 132 are connected through a CAN bus (Controller Area Network, local area network bus of the control module 132). The detection component 133 can be set as a lidar, a receiver, and a camera, and the control module 132 can be set as a vehicle control module and a stabilizer bar control module. When the all-terrain vehicle 100 is traveling on the first preset road condition, the operator operates the operating component 131 to switch the left torsion bar 1411 and the right torsion bar 1412 to the active mode. When the all-terrain vehicle 100 is traveling, the lidar scans the road surface ahead, the receiver receives the laser beam reflected from the road surface irradiated by the lidar, the receiver generates a reception signal and generates a point cloud, the camera takes pictures of the road surface ahead, and the point cloud and image data are transmitted to the vehicle control module. The vehicle control module constructs a ground model by algorithmically fusing the point cloud map and the image information, and identifies whether the all-terrain vehicle 100 passes through the first preset road condition through the algorithm. If it is judged that it will pass, the vehicle control module plans based on the distance information, vehicle speed, and vehicle steering angle of the laser sensor, and the vehicle control module sends the planned signal to the stabilizer bar control module through the CAN bus. When the detection component 133 detects that the all-terrain vehicle 100 is away from the first preset road condition, the stabilizer bar control module controls the connection of the left torsion bar 1411 and the right torsion bar 1412. When the detection component 133 detects that the all-terrain vehicle 100 passes through or approaches the first preset road condition, the stabilizer bar control module 132 controls the left torsion bar 1411 and the right torsion bar 1412 to be in a relative movement state.

[0029] Such as Figure 4 and Figure 5As shown, more specifically, the stabilizer bar assembly 141 further includes a housing 1413. An accommodation space 1415 is formed around the housing 1413. The accommodation space 1415 includes a first liquid chamber 1415a and a second liquid chamber 1415b. The left torsion bar 1411 and the right torsion bar 1412 are at least partially disposed in the first liquid chamber 1415a. The oil passage 1414 is in a connected state, and the first liquid chamber 1415a and the second liquid chamber 1415b are in communication; when the oil passage 1414 is in a disconnected state, the first liquid chamber 1415a and the second liquid chamber 1415b are separated. With the above arrangement, when the operator operates the operating member 131 to control the left torsion bar 1411 and the right torsion bar 1412 to be in a disconnected mode, or when the left torsion bar 1411 and the right torsion bar 1412 are in an active mode, the all-terrain vehicle 100 passes through a first preset road condition. At this time, the oil passage 1414 is in a connected state. The separation of the left torsion bar 1411 and the right torsion bar 1412 will squeeze the oil. The oil squeezed by the separation of the left torsion bar 1411 and the right torsion bar 1412 in the first liquid chamber 1415a can be transported to the second liquid chamber 1415b through the oil passage 1414. Also, since the connection between the left torsion bar 1411 and the right torsion bar 1412 is a claw disc with an inclined surface, when there is too much oil in the first liquid chamber 1415a, it will cause too much resistance to the relative movement of the left torsion bar 1411 and the right torsion bar 1412, so that the left torsion bar 1411 and the right torsion bar 1412 can move relative to each other to adapt to different road conditions, thereby improving the driving stability of the all-terrain vehicle 100.

[0030] As Figures 2 to 6As shown, as an implementation, the stabilizer bar assembly 141 includes a control valve 1416. The control valve 1416 is used to switch the state of the oil passage 1414. The control valve 1416 is disposed in the accommodation space 1415. The control valve 1416 has an open state and a closed state. The control module 132 controls the control valve 1416 to switch between the open state and the closed state. At least a part of the control valve 1416 is formed with a passage (not shown in the figure), and the passage is used for the oil fluid to pass through. When the control module 132 controls the control valve 1416 to be in the open state, the passage is communicated with the first liquid chamber 1415a, and the oil passage 1414 is in a communicated state; when the control module 132 controls the control valve 1416 to be in the closed state, the passage is separated from the first liquid chamber 1415a, and the oil passage 1414 is in a disconnected state. When the operator operates the operating member 131 to switch the left torsion bar 1411 and the right torsion bar 1412 to the disconnected mode, or when the left torsion bar 1411 and the right torsion bar 1412 are in the active mode and the all-terrain vehicle 100 approaches the first preset road condition, the control valve 1416 is in the open state to form a passage for the oil fluid to pass through, so that the oil passage 1414 is in a communicated state, and the left torsion bar 1411 and the right torsion bar 1412 can move relatively. The left torsion bar 1411 and the right torsion bar 1412 squeeze the oil fluid, and the oil fluid in the first liquid chamber 1415a can enter the second liquid chamber 1415b through the passage; when the operator operates the operating member 131 to switch the left torsion bar 1411 and the right torsion bar 1412 to the locked mode, or when the left torsion bar 1411 and the right torsion bar 1412 are in the active mode and the all-terrain vehicle 100 is away from the first preset road condition, the control valve 1416 is in the closed state, and the oil passage 1414 is in a disconnected state. Through the above settings, the control module 132 only needs to control the control valve, so that the oil passage 1414 can be switched between the connected state and the disconnected state, thereby reducing the switching time of the oil passage 1414 between the connected state and the disconnected state, improving the switching efficiency of the oil passage 1414 between the connected state and the disconnected state, reducing the time for the oil fluid squeezed by the relative movement of the left torsion bar 1411 and the right torsion bar 1412 to enter the second liquid chamber 1415b, improving the relative movement efficiency of the left torsion bar 1411 and the right torsion bar 1412, and further improving the adaptability of the all-terrain vehicle 100 to different road conditions.

[0031] Specifically, the control valve 1416 includes a first control valve 1416a and a second control valve 1416b. The oil passage 1414 includes a first passage and a second passage (not shown in the figure). The control module 132 controls both the first control valve 1416a and the second control valve 1416b to open, and the oil passage 1414 is in a connected state; the control module 132 controls both the first control valve 1416a and the second control valve 1416b to close, and the oil passage 1414 is in a disconnected state. Through the above settings, the control module 132 can control the opening and closing of the first control valve 1416a and the second control valve 1416b, so that the oil passage 1414 is in different states, so that both the left torsion bar 1411 and the right torsion bar 1412 can be adjusted to different states to meet the needs of the all-terrain vehicle 100 passing through different road conditions, thereby improving the adaptability of the all-terrain vehicle 100 to different road conditions.

[0032] As an implementation, when the left torsion bar 1411 and the right torsion bar 1412 are in the active mode, the oil passage 1414 further includes a preparation state and a recovery state. The first control valve 1416a is open, the second control valve 1416b is closed, and the oil passage 1414 is in the preparation state; the first control valve 1416a is closed, the second control valve 1416b is open, and the oil passage 1414 is in the recovery state. Specifically, when the detection member 133 detects that the all-terrain vehicle 100 is about to move away from the first preset road condition, the detection member 133 transmits the detected data to the control module 132, so that the control module 132 controls the first control valve 1416a to open, and the control module 132 controls the second control valve 1416b to close, and the oil passage 1414 is in the preparation state. At this time, the left torsion bar 1411 and the right torsion bar 1412 change from the relative movement state to the connected state. When the detection member 133 detects that the all-terrain vehicle 100 has moved away from the first preset road condition, the detection member 133 transmits the detected data to the control module 132. The control module 132 controls the control module 132 to control the first control valve 1416a to close, and the control module 132 controls the second control valve 1416b to open, and the oil passage 1414 is in the recovery state. At this time, the left torsion bar 1411 and the right torsion bar 1412 are in the connected state. Through the above settings, the control module 132 only needs to control the opening and closing of the first control valve 1416a and the second control valve 1416b to switch different states of the oil passage 1416, so that the oil passage 1416 can be switched between different states, so that the stabilizer bar assembly 141 can adapt to different road conditions, and further the all-terrain vehicle 100 can adapt to different road conditions.

[0033] Such as Figure 4 、 Figure 5 and Figure 7As shown, as an implementation, the stabilizer bar assembly 141 includes a piston 1417, and the electrical assembly 13 includes a driving member 134. The driving member 134 is used to drive the piston 1417 to move. The piston 1417 is connected to the driving member 134. At least a part of the piston 1417 is disposed in the second liquid chamber 1415b, and the driving member 134 is connected to the housing 1413. The piston 1417 includes a first position and a second position. When an operator operates the operating member 131 and the operating member 131 controls the left torsion bar 1411 and the right torsion bar 1412 to be in the active mode, the detection member 133 detects that the all-terrain vehicle 100 is about to move away from the first preset road condition, and the driving member 134 drives the piston 1417 to move from the second position to the first position. When the detection member 133 detects that the all-terrain vehicle 100 moves away from the first preset road condition, the driving member 134 drives the piston 1417 to move from the first position to the second position. When the detection member 133 detects that the all-terrain vehicle 100 is about to move away from the first preset road condition, the oil circuit 1414 is in a ready state. The control module 132 controls the first control valve 1416a to open, and the control module 132 controls the second control valve 1416b to close. At this time, the driving member 134 drives the piston 1417 to move from the first position to the second position. The displacement of the piston 1417 reduces the space in the second liquid chamber 1415b, thereby increasing the internal pressure of the second liquid chamber 1415b, so that the oil in the second liquid chamber 1415b is accelerated to be transported to the first liquid chamber 1415a, and further the oil can push the left torsion bar 1411 or the right torsion bar 1412 to displace, so that the right torsion bar 1412 and the right torsion bar 1412 are connected. When the detection member 133 detects that the all-terrain vehicle 100 moves away from the first preset road condition, the oil circuit 1414 is in a recovery state. The first control valve 1416a closes, and the control module 132 controls the second control valve 1416b to open. At this time, the driving member 134 drives the piston 1417 to move from the first position to the second position to restore the pressure difference in the accommodation space 1415. Through the above settings, the connection time of the left torsion bar 1411 and the right torsion bar 1412 can be reduced, that is, the time for the left torsion bar 1411 and the right torsion bar 1412 to switch from the active state to the locked state is reduced, and the stability of the all-terrain vehicle 100 is improved. Among them, the first position refers to the position where the piston 1417 is close to the oil circuit 1414; the second position refers to the position where the piston 1417 is far from the oil circuit 1414; the driving member 134 can be set as a motor.

[0034] As an implementation, the stabilizer bar assembly 141 further includes a transmission member 1418. The transmission member 1418 is used to drive the power of the driving member 134 to the piston 1417. One end of the transmission member 1418 is connected to the driving member 134, and the other end of the transmission member 1418 is connected to the piston 1417. Through the above arrangement, the driving member 134 can drive the piston 1417 to move through the transmission member 1418, so that the driving member 134 can be arranged outside the accommodation space 1415, thereby reducing the volume of the stabilizer bar assembly 141 to reduce the interference between the stabilizer bar assembly 141 and the components of the all-terrain vehicle 100, thereby improving the working stability of the all-terrain vehicle 100. Among them, the transmission member 1418 can be set as a worm.

[0035] As an implementation, the piston 1417 includes a first piston 1417a and a second piston 1417b. The second piston 1417b is used to drive the first piston 1417a to perform a reciprocating linear motion. The transmission member 1418 is connected to the second piston 1417b, and the first piston 1417a and the second piston 1417b are connected. Through the above arrangement, when the detection member 133 detects that the all-terrain vehicle 100 is about to move away from the first preset road condition, the driving member 134 drives the transmission member 1418 to rotate clockwise. The transmission member 1418 drives the second piston 1417b to move, and the second piston 1417b drives the first piston 1417a to move from the second position to the first position; when the detection member 133 detects that the all-terrain vehicle 100 moves away from the first preset road condition, the driving member 134 drives the transmission member 1418 to rotate counterclockwise. The transmission member 1418 drives the second piston 1417b to move, and the second piston 1417b drives the first piston 1417a to move from the first position to the second position, so as to accelerate the movement of the oil fluid from the second liquid chamber 1415b to the first liquid chamber 1415a, improve the connection speed between the left torsion bar 1411 and the right torsion bar 1412, so that the stabilizer bar assembly 141 always maintains balance, and improve the adaptability of the all-terrain vehicle 100 to different road conditions.

[0036] As another implementation, a seal member 1419 and a seal groove 141a are further provided on the piston 1417. The seal member 1419 is at least partially arranged in the seal groove 141a. Through the above arrangement, the stability of the seal member 1419 can be improved, preventing the seal member 1419 from falling off the transmission member 1419 when the piston 1417 moves, and also preventing the oil fluid in the second liquid chamber 1415b from leaking out, avoiding damage to the components of the all-terrain vehicle 100 due to long-term immersion in oil fluid, thereby improving the working stability of the all-terrain vehicle 100.

[0037] In this embodiment, the specific implementation of the left torsion bar 1411 and the right torsion bar 1412 in the active mode is as follows: When the detector 133 detects that the all-terrain vehicle 100 is approaching the first preset road condition, the detector 133 transmits the detected data to the control module 132, causing the control module 132 to control the opening of the first control valve 1416a and the second control valve 1416b, so that the oil circuit 1414 is in a connected state, and the left torsion bar 1411 and the right torsion bar 1412 are in a relative movement state; When the all-terrain vehicle 100 passes through the first preset road condition, the control module 132 controls the opening of the first control valve 1416a and the second control valve 1416b, so that the oil circuit 1414 is in a connected state, and the left torsion bar 1411 and the right torsion bar 1412 are separated. The oil is squeezed due to the separation of the right torsion bar 1412 and the right torsion bar 1412, and the oil moves from the first liquid chamber 1415a to the second liquid chamber 1415b to improve the separation efficiency of the left torsion bar 1411 and the right torsion bar 1412; When the detector 133 detects that the all-terrain vehicle 100 is about to move away from the first preset road condition, the detector 133 transmits the detected data to the control module 132. The first control valve 1416a is opened, and the second control valve 1416b is closed. The left torsion bar 1411 and the right torsion bar 1412 are separated, and the oil circuit 1414 is in a standby state. At this time, the driving member 134 drives the piston 1417 to move from the second position to the first position, and the oil accelerates from the second liquid chamber 1415b to the first liquid chamber 1415a to improve the connection speed of the left torsion bar 1411 and the right torsion bar 1412; When the detector 133 detects that the all-terrain vehicle 100 has moved away from the first preset road condition, the detector 133 transmits the detected data to the control module 132. The control module 132 controls the closing of the first control valve 1416a, and the control module 132 controls the opening of the second control valve 1416b. The oil circuit 1414 is in a restored state. After the driving member 134 drives the piston 1417 to move from the first position to the second position, the control module 132 controls the closing of the first control valve 1416a, and the control module 132 controls the opening of the second control valve 1416b. The oil circuit 1414 is in a disconnected state, and the left torsion bar 1411 and the right torsion bar 1412 are in a connected state.
