Description

Technical Field

[0001] The present disclosure relates to the technical field of steering, and specifically, to a tie rod steering device and a vehicle. Background Art

[0002] With the popularization of vehicle industry intelligence, people's attention to the life cycle of vehicle components has become higher and higher. In a vehicle, a tie rod steering system is generally adopted, and steering operation is achieved through the relative movement between a tie rod and a knuckle arm. The connection of the tie rod must rely on a ball joint, so the service life of the ball joint becomes a key link in the steering system. The ball joint and the ball seat are connected in the form of a ball hinge joint. During the steering process, relative movement occurs between the ball joint and the ball seat, generating friction, and long-term friction will cause wear of the ball joint. The wear condition of the ball joint can directly affect the steering return performance. When the wear amount of the ball joint is greater than a preset wear amount, abnormal noise will even occur and the steering wheel will shake, greatly reducing the steering performance and driving experience of the vehicle.

[0037] The following is a detailed description of the specific embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining and understanding the present disclosure, and are not used to limit the present disclosure.

[0038] Before introducing the specific embodiments of the present disclosure in detail, the application scenarios of the present disclosure are described as follows. The present disclosure can be applied to the tie-rod steering system of a vehicle. In the tie-rod steering system, the steering operation is achieved through the relative movement between the tie rod and the steering knuckle arm. And the connection of the tie rod must rely on the ball joint, so the service life of the ball joint becomes a key link in the steering system. The ball joint and the ball seat are connected in the form of a ball hinge joint. During the steering process, relative movement occurs between the ball joint and the ball seat, generating friction, and long-term friction will cause wear of the ball joint. The wear condition of the ball joint can directly affect the steering return performance. When the wear amount of the ball joint is greater than the preset wear amount, abnormal noise may even occur and the steering wheel may shake, greatly reducing the steering performance, safety performance and driving experience of the vehicle.

[0039] To solve the above technical problems, the present disclosure provides a tie-rod steering device and a vehicle. The device includes at least one set of wear monitoring components and a controller. The wear monitoring components include a tie-rod ball joint, a ball seat and a signal acquisition component. The tie-rod ball joint is arranged on the ball seat, and the signal acquisition component is embedded in the part of the tie-rod ball joint that contacts the ball seat. The signal acquisition component is used to contact the ball seat when the target wear amount at the contact part between the tie-rod ball joint and the ball seat reaches the preset wear amount, and to rub against the ball seat when the tie-rod ball joint and the ball seat move relatively. The signal acquisition component includes a signal acquisition circuit connected to the controller, and is used to send a target open-circuit signal to the controller when it is determined that the signal acquisition circuit is in an open-circuit state during the friction between the tie-rod ball joint and the ball seat. The controller is used to output a target prompt message when receiving the target open-circuit signal. The target prompt message is used to indicate that the wear amount of the tie-rod ball joint has reached a specified degree. In this way, by outputting the target prompt message when it is determined that the signal acquisition circuit is in an open-circuit state during the friction between the tie-rod ball joint and the ball seat, it is possible to timely remind the user through the target prompt message that the steering performance of the vehicle has decreased when the wear amount of the tie-rod ball joint reaches a specified degree, thereby avoiding the phenomenon of steering wheel shaking during the driving of the whole vehicle caused by the reduction of steering performance, and further effectively improving the safety performance of the vehicle and the driving experience of the user.

[0040] Figure 1 is a schematic diagram of a tie-rod steering device shown according to an exemplary embodiment of the present disclosure; as Figure 1As shown, the tie rod steering device 100 includes at least one set of wear monitoring components 101 and a controller 102. The wear monitoring components 101 include a tie rod ball head 1011, a ball seat 1012, and a signal acquisition component 1013;

[0041] The tie rod ball head 1011 is arranged on the ball seat 1012, and the signal acquisition component 1013 is embedded in the portion of the tie rod ball head 1011 that contacts the ball seat 1012;

[0042] The signal acquisition component 1013 is configured to contact the ball seat 1012 when the target wear amount at the contact portion between the tie rod ball head 1011 and the ball seat 1012 reaches a preset wear amount, and to rub against the ball seat 1012 when the tie rod ball head 1011 and the ball seat 1012 move relative to each other;

[0043] The signal acquisition component 1013 includes a signal acquisition circuit S1 connected to the controller 102, and is configured to send a target open circuit signal to the controller 102 if it is determined that the signal acquisition circuit S1 is in an open circuit state during the rubbing process between the tie rod ball head 1011 and the ball seat 1012;

[0044] The controller 102 is configured to output a target prompt message when receiving the target open circuit signal.

[0045] Wherein, the signal acquisition component 1013 includes a signal acquisition circuit S1 connected to the controller 102. The target prompt message is used to indicate that the wear amount of the tie rod ball head 1011 has reached a specified degree. The target prompt message can be a sound alarm message. When the wear amount of the tie rod ball head 1011 reaches the specified degree, a beeping sound is emitted to remind. Or, when the wear amount of the tie rod ball head 1011 reaches the specified degree, a pre-recorded voice prompt is played, such as "The tie rod ball head is worn, please check". The target prompt message can be a light alarm message. An LED (Light Emitting Diode) indicator light can be set on the instrument panel or the maintenance panel. When the wear amount of the tie rod ball head 1011 reaches the specified degree, the LED indicator light is lit. Or, when the wear amount of the tie rod ball head 1011 reaches the specified degree, a flashing light is used to attract attention, such as a red warning light. The target prompt message can be a vibration alarm message. When the wear amount of the tie rod ball head 1011 reaches the specified degree, the driver is reminded by seat vibration. Or, a vibration unit is installed on the steering wheel. When the wear amount of the tie rod ball head 1011 reaches the specified degree, the driver is reminded in a vibrating manner. The target prompt message can be a combined alarm message. When the wear amount of the tie rod ball head 1011 reaches the specified degree, both sound and light alarms are used simultaneously to enhance the warning effect.

[0046] The friction between the tie rod ball head 1011 and the ball seat 1012 is mainly sliding friction. When the vehicle steers, the contact surface between the tie rod ball head 1011 and the ball seat 1012 will slide relatively. At the part of the tie rod ball head 1011 that contacts the ball seat 1012, the signal acquisition component 1013 is embedded in the tie rod ball head 1011; during the friction process between the tie rod ball head 1011 and the ball seat 1012, if it is determined that the signal acquisition component 1013 is worn out by the ball seat 1012, that is, it is determined that the signal acquisition circuit S1 is in an open circuit state, a target open circuit signal is sent to the controller 102 to output the target prompt information in a timely manner when the wear amount of the tie rod ball head 1011 reaches a specified degree.

[0047] In the above technical solution, by outputting the target prompt information when it is determined that the signal acquisition circuit is in an open circuit state during the friction process between the tie rod ball head and the ball seat, it can remind the user in a timely manner through the target prompt information that the steering performance of the vehicle has decreased when the wear amount of the tie rod ball head reaches a specified degree, thereby avoiding the phenomenon of the steering wheel shaking during the driving of the whole vehicle caused by the reduction of the steering performance, and further effectively improving the safety performance of the vehicle and the driving experience of the user.

[0048] Optionally, a hole 1014 is provided at the part of the tie rod ball head 1011 that contacts the ball seat 1012, and the signal acquisition component 1013 is embedded in the hole 1014, and the distance between the signal acquisition component 1013 and the outer surface of the tie rod ball head 1011 is a preset distance.

[0049] Wherein, the hole 1014 is located inside the tie rod ball head 1011 at the part of the tie rod ball head 1011 that contacts the ball seat 1012. The preset distance is the safe wear distance between the tie rod ball head 1011 and the ball seat 1012. If the safe wear distance is exceeded, it may cause a decrease in the steering return performance and the phenomenon of the steering wheel shaking during the driving of the whole vehicle.

[0050] It should be noted that the signal acquisition component 1013 is installed by drilling holes on the side end of the tie rod ball joint 1011 (the part of the tie rod ball joint 1011 that contacts the ball seat 1012). The signal acquisition component 1013 is inserted into the tie rod ball joint 1011, and the distance from the inner surface of the ball head is the safe wear distance. When the tie rod ball joint 1011 and the ball seat 1012 move relative to each other to generate friction, when the wear amount of the tie rod ball joint 1011 does not reach the safe wear distance, the signal acquisition circuit S1 is in a conducting state and does not send a target open circuit signal to the controller 102; when the wear amount of the tie rod ball joint 1011 reaches the safe wear distance, if it is determined that the signal acquisition component 1013 is worn out, that is, the signal acquisition circuit S1 is in an open circuit state, a target open circuit signal is sent to the controller 102.

[0051] Exemplarily, the safe wear distance is 0.6 mm. The signal acquisition component 1013 is inserted into the tie rod ball joint 1011, and the distance from the inner surface of the ball head is 0.6 mm. When the tie rod ball joint 1011 and the ball seat 1012 move relative to each other to generate friction, when the wear amount of the tie rod ball joint 1011 does not reach 0.6 mm, the signal acquisition circuit S1 is in a conducting state and does not send a target open circuit signal to the controller 102; when the wear amount of the tie rod ball joint 1011 reaches 0.6 mm, if it is determined that the signal acquisition circuit S1 is worn out by the ball seat 1012, that is, the signal acquisition circuit S1 is in an open circuit state, a target open circuit signal is sent to the controller 102.

[0052] In the above technical solution, by embedding the signal acquisition component in the hole, and the distance between the signal acquisition component and the outer surface of the tie rod ball joint is the preset distance, when the wear amount of the tie rod ball joint reaches a specified degree, a target open circuit signal can be sent to the controller through the signal acquisition component, providing data support for subsequently timely reminding the user through the target prompt information that the steering performance of the vehicle has deteriorated.

[0053] Figure 2 is according to Figure 1 shown in the schematic diagram of a tie rod steering device according to the embodiment shown, as Figure 2 shown,

[0054] The signal acquisition circuit S1 includes an induction coil LC and an electromagnet EM;

[0055] The induction coil LC is arranged at a first position in the hole 1014, and the electromagnet EM is arranged at a second position in the hole 1014;

[0056] The distance between the first position and the outer surface of the tie rod ball head 1011 is less than the distance between the second position and the outer surface of the tie rod ball head 1011.

[0057] The signal acquisition component 1013 is configured to obtain the induced voltage generated by the electromagnet EM and the induction coil LC when relative movement occurs between the tie rod ball head 1011 and the ball seat 1012. If it is determined that the induced voltage is zero, it is determined that the signal acquisition circuit S1 is in an open circuit state, and the target open circuit signal is sent to the controller 102.

[0058] Wherein, when friction occurs between the tie rod ball head 1011 and the ball seat 1012, the position of the tie rod ball head 1011 relative to the ball seat 1012 changes. Both the electromagnet EM and the induction coil LC are located inside the tie rod ball head 1011. During the relative movement between the tie rod ball head 1011 and the ball seat 1012, the tie rod ball head 1011 rotates or tilts relative to the ball seat 1012. Even if the distance between the induction coil LC and the electromagnet EM remains unchanged, the angle of the electromagnet EM relative to the induction coil LC will change, resulting in a change in the effective magnetic field strength passing through the induction coil LC. According to Faraday's law of electromagnetic induction, when the magnetic flux passing through a closed loop changes, an electromotive force (i.e., induced voltage) will be generated in the loop.

[0059] It should be noted that the induction coil LC is arranged at a first position in the hole 1014, and the electromagnet EM is arranged at a second position in the hole 1014; the distance between the first position and the outer surface of the tie rod ball head 1011 is less than the distance between the second position and the outer surface of the tie rod ball head 1011. During the process of friction between the tie rod ball head 1011 and the ball seat 1012, the ball seat 1012 grinds off the induction coil LC in the signal acquisition circuit S1, so that the induction coil LC is no longer a complete closed loop. According to Faraday's law of electromagnetic induction, an induced electromotive force will only be generated in a closed loop. Therefore, once the induction coil LC is ground off, a closed loop cannot be formed again, and no induced voltage can be generated. At this time, the induced voltage is zero, that is, it can be determined that the signal acquisition circuit S1 is in an open circuit state. After determining that the signal acquisition circuit S1 is in an open circuit state, the target open circuit signal is sent to the controller 102.

[0060] The above technical solution can provide data support for subsequently reminding the user in a timely manner through the target prompt information that the steering performance of the vehicle has deteriorated by arranging the induction coil at the first position in the hole, arranging the electromagnet at the second position in the hole, and determining that the signal acquisition circuit is in an open circuit state according to the induced voltage.

[0066] the signal acquisition component 1013 in the first rear-side wear monitoring component 105 is configured to, during the friction between the tie rod ball head 1011 and the ball seat 1012 in the first rear-side wear monitoring component 105, if it is determined that the signal acquisition circuit S1 in the first rear-side wear monitoring component 105 is in an open circuit state, send a second target open circuit signal to the controller 102;

[0067] the controller 102 is configured to output the target prompt information when it is determined that the first target open circuit signal or the second target open circuit signal is received.

[0068] Wherein, during the friction between the tie rod ball head 1011 and the ball seat 1012 in the first front-side wear monitoring component 104, the induced voltage generated by the electromagnet EM and the induction coil LC in the first front-side wear monitoring component 104 is acquired. If it is determined that the induced voltage is zero, it is determined that the signal acquisition circuit S1 is in an open circuit state, and the first target open circuit signal is sent to the controller 102.

[0069] During the friction between the tie rod ball joint 1011 in the first rear wear monitoring component 105 and the ball seat 1012 in the first rear wear monitoring component 105, obtain the induced voltage generated by the electromagnet EM and the induction coil LC in the first rear wear monitoring component 105. If it is determined that the induced voltage is zero, determine that the signal acquisition circuit S1 is in an open circuit state, and send the second target open circuit signal to the controller 102.

It can send the target open circuit signal to the controller in time when an abnormality occurs in one of the wear monitoring components in the tie rod steering device, providing data support for subsequently reminding the user through the target prompt information that the steering performance of the vehicle has decreased.

[0071] Optionally, as Figure 3 shown, the device further includes a steering tie rod 106, and the at least one set of wear monitoring components includes a second front wear monitoring component 107 and a second rear wear monitoring component 108;

[0072] The second front wear monitoring component 107 is disposed at one end of the steering tie rod 106, and the second rear wear monitoring component 108 is disposed at the other end of the steering tie rod 106.

[0073] Optionally, as Figure 3 shown, the second front wear monitoring component 107 and the second rear wear monitoring component 108 are respectively connected to the controller 102;

[0074] The signal acquisition component 1013 in the second front wear monitoring component 107 is configured to send a third target open circuit signal to the controller 102 when it is determined that the signal acquisition circuit S1 in the second front wear monitoring component 107 is in an open circuit state during the friction between the tie rod ball joint 1011 in the second front wear monitoring component 107 and the ball seat 1012 in the second front wear monitoring component 107;

[0075] The signal acquisition component 1013 in the second rear wear monitoring component 108 is configured to send a fourth target open circuit signal to the controller 102 when it is determined that the signal acquisition circuit S1 in the second rear wear monitoring component 108 is in an open circuit state during the friction between the tie rod ball joint 1011 in the second rear wear monitoring component 108 and the ball seat 1012 in the second rear wear monitoring component 108;

[0076] The controller 102 is configured to output the target prompt information when it is determined that the third target open - circuit signal or the fourth target open - circuit signal is received.

[0077] During the process of friction between the tie - rod ball head 1011 and the ball seat 1012 in the second front - side wear monitoring component 107, the induced voltage generated by the electromagnet EM and the induction coil LC in the second front - side wear monitoring component 107 is acquired. If it is determined that the induced voltage is zero, it is determined that the signal acquisition circuit S1 is in an open - circuit state, and the third target open - circuit signal is sent to the controller 102.

[0078] During the process of friction between the tie - rod ball head 1011 and the ball seat 1012 in the second rear - side wear monitoring component 108, the induced voltage generated by the electromagnet EM and the induction coil LC in the second rear - side wear monitoring component 108 is acquired.

[0080] Figure 4 is according to Figure 1 Another schematic diagram of a tie - rod steering device shown in the illustrated embodiment, as Figure 4 shown,

[0081] The device further includes a reset switch 109 and an alarm component 1010, and the controller 102 is respectively connected to the reset switch 109 and the alarm component 1010;

[0082] The controller 102 is configured to activate the alarm component 1010 when it is determined that the target prompt information is output;
