Description

Technical Field

[0001] The utility model relates to the technical field of vehicles, in particular to a steering limiting mechanism and a vehicle. Background Art

[0002] Rear-wheel steering can reduce the turning radius of the vehicle when turning at low speed and increase turning flexibility; it can increase the turning radius at high speed and improve the high-speed handling stability of the vehicle. The existing rear wheel is equipped with a steering limit mechanism to ensure the reliability of rear-wheel steering. The existing steering limit mechanism includes a moving shaft, a sliding block of a sensor and a limit housing. The sliding block of the sensor moves with the moving shaft in the limit housing. The sliding block of the sensor and the limit housing cooperate with each other to limit the moving shaft from moving up and down or rotating in the circumferential direction.

[0003] However, the sliding block of the sensor is prone to wear and damage due to long-term friction, resulting in an increasingly larger gap between the sliding block of the sensor and the limit housing. The sliding block of the sensor will also swing up and down with the moving shaft, reducing the sensitivity of the sensor and ultimately causing the steering gear self-locking to fail.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] One of the core concepts of the embodiment of the utility model is to disclose a steering limit mechanism, such as Figure 1 As shown, the steering limit mechanism includes a limit shell 1 and a connecting member 2; wherein the connecting member 2 is arranged in the limit shell 1, a first limit member 21 is arranged on the connecting member 2, and a second limit member 12 is arranged on the limit shell 1, and the second limit member 12 and the first limit member 21 are slidably matched to limit the movement of the connecting member 2.

[0034] In the embodiment of the utility model, the connecting member 2 is arranged in the limiting shell 1, and the connecting member 2 is provided with a first limiting member 21, and the limiting shell 1 is provided with a second limiting member 12, and the second limiting member 12 is suitable for sliding cooperation with the first limiting member 21, so that the second limiting member 12 and the first limiting member 21 can only slide relative to each other, that is, the first limiting member 21 can only reciprocate linearly relative to the second limiting member 12. The steering limiting mechanism is used in cooperation with the rear wheel to ensure the reliability of the rear wheel steering. Moreover, the steering limiting mechanism realizes the limitation through the sliding cooperation between the connecting member 2 and the limiting shell 1, that is, the limitation does not rely on the sensor 4, which can reduce the friction loss of the sensor 4, and then ensure the sensitivity of the sensor 4, and improve the self-locking reliability of the steering gear.

[0035] In the embodiment of the utility model, the steering limit mechanism can be applied to a steering gear to control the steering of a wheel. The steering limit mechanism can include a limit housing 1 and a connecting member 2, and the connecting member 2 can be installed on the limit housing 1 to protect the connecting member 2.

[0036] Specifically, a first limit member 21 is provided on the connecting member 2, and a second limit member 12 is provided on the limit shell 1; the first limit member 21 and the second limit member 12 are correspondingly arranged and limitedly cooperated, so that the first limit member 21 can reciprocate linearly relative to the second limit member 12, and can only reciprocate linearly, thereby limiting the movement of the connecting member 2 in other directions, and the connecting member 2 can be connected to the structure to be limited, thereby limiting the movement of the structure to be limited.

[0037] Specifically, the first position-limiting member 21 and the second position-limiting member 12 are arranged in a one-to-one correspondence; the correspondingly arranged first position-limiting member 21 and the second position-limiting member 12 are limitedly matched and slidably connected, which can effectively limit the movement direction of the connecting member 2.

[0038] Furthermore, when the steering limiting mechanism is applied to a wheel steering system, that is, the structure to be limited can be a wheel, the rotation angle of the wheel can be effectively limited, thereby improving the precise control of wheel steering and increasing driving accuracy and stability.

[0039] Specifically, Figure 1 As shown, the first limiter 21 and the second limiter 12 slide together along the X direction, so that the connecting member 2 can only move along the X-axis direction, which can limit the horizontal movement of the connecting member 2 along the Y direction and the Z direction, and can also limit the rotation of the connecting member 2 around the X direction.

[0040] In the embodiment of the utility model, the connecting member 2 and the limiting housing 1 are slidably matched by the first limiting member 21 and the second limiting member 12, so that the steering limiting mechanism has high reliability and strong applicability, and at the same time has a simple structure and is easy to operate.

[0041] Optionally, one of the first limit member 21 and the second limit member 12 is a sliding groove, and the other is a limit boss; at least a portion of the limit boss is embedded in the sliding groove and slidingly cooperates with the sliding groove, which can improve the reliability of the limit cooperation between the first limit member 21 and the second limit member 12, avoid the first limit member 21 and the second limit member 12 from disengaging, and thereby improve the reliability of the sliding cooperation between the steering limit mechanism.

[0042] Specifically, the first limiting member 21 is a sliding groove, and the corresponding second limiting member 12 is a limiting boss; or, the first limiting member 21 is a limiting boss, and the corresponding first limiting member 21 is a sliding groove.

[0044] In the embodiment of the utility model, the first limiting member 21 is arranged on the outer periphery of the connecting member 2. Since the connecting member 2 is arranged in the limiting shell 1, it is convenient to realize that at least part of the first limiting member 21 is embedded in the second limiting member 12, thereby improving the convenience and reliability of the sliding fit between the first limiting member 21 and the second limiting member 12, and the second limiting member 12 can also play a reliable limiting role on the first limiting member 21.

[0045] Optionally, the first position-limiting member 21 is an annular structure arranged in the circumferential direction of the connecting member 2 , so that any position of the first position-limiting member 21 in the circumferential direction can cooperate with the second position-limiting member 12 , which can reduce the difficulty of installing the first position-limiting member 21 .

[0046] Optionally, the second limiting member 12 extends along the first direction and partially extends to the inner wall of the limiting shell 1 along the second direction, and the second direction intersects with the first direction. In this way, the second limiting member 12 can form a runway-shaped structure, and the second limiting member 12 is a closed structure, which can limit the first limiting member 21 and prevent the first limiting member 21 from sliding beyond the travel.

[0047] Specifically, combined Figures 1 to 3 As shown, the first limiting member 21 is an annular protrusion, and the corresponding second limiting member 12 is a racetrack-shaped groove. The annular protrusion can reciprocate linearly in the racetrack-shaped groove, thereby limiting the connecting member 2 to only reciprocate linearly in the limiting housing 1.

[0048] Optionally, the number of the second limiting members 12 may include two, and the two second limiting members 12 are respectively arranged on two opposite side walls of the limiting housing 1; the second limiting members 12 extend along the first direction.

The second limiters 12 are respectively arranged on two opposite side walls of the limiter housing 1, so that the opposite sides of the connecting member 2 can be respectively connected to the limiter housing 1 in a limit position, which can improve the reliability and stability of the fit between the connecting member 2 and the limiter housing 1.

[0050] Specifically, the two second limiting members 12 can be provided independently.

[0051] Optionally, the number of the first limiting members 21 includes two, and the two first limiting members 21 are respectively arranged on two opposite sides of the connecting member 2 .

[0052] In an embodiment of the utility model, two first limiting members 21 can be independently arranged on opposite sides of the connecting member 2, and both opposite sides of the connecting member 2 can be limitedly matched with the limiting shell 1 through the first limiting members 21, which can improve the reliability and stability of the matching between the connecting member 2 and the limiting shell 1.

[0053] Optionally, the steering limiting mechanism may further include a sensor 4 , and the sensor 4 may be connected to the connecting member 2 via a buffer component 5 .

[0054] In the embodiment of the utility model, the sensor 4 is connected to the connecting member 2, and can be used to detect the movement stroke of the connecting member 2, so as to accurately control the movement stroke of the connecting member 2. Moreover, the sensor 4 is connected to the connecting member through the buffer component 5, which can improve the reliability of the assembly between the sensor 4 and the connecting member 2.

[0055] Specifically, the sensor 4 can be a linear displacement sensor 4, or an angle sensor 4, which is used to obtain the displacement of the connecting member 2, and can provide accurate steering position information for the vehicle dynamic control system, which is conducive to real-time adjustment and optimization of vehicle performance. Specifically, the linear displacement sensor has high displacement accuracy, low price, easy control and measurement of displacement, simple structure and software and hardware requirements, and simple replacement and disassembly; the angle sensor occupies less space.

[0056] Optionally, the sensor 4 includes a shell 41 and a sliding member 42; the shell 41 is connected to the limit shell 1, and is enclosed with the limit shell 1 to form a accommodating cavity for placing the sliding member 42 and the connecting member 2; the sliding member 42 is slidably connected to the shell 41, and the sliding member 42 is tightly matched with the connecting member 2 through the buffer component 5.

[0057] In the embodiment of the utility model, the sliding member 42 is closely matched with the connecting member 2 through the buffer component 5, which can improve the reliability of the installation between the sliding member 42 and the connecting member 2. The buffer component 5 can also play a buffering role, preventing the sliding member 42 from shaking during the movement, reducing the friction between the sliding member 42 and the connecting member 2, and increasing the service life of the sliding member 42 and the connecting member 2, which can prevent the sensor 4 from being damaged, and significantly improve the measurement accuracy of the sensor 4.

[0058] Specifically, the buffer component 5 may be an O-ring, and the material of the buffer component 5 may be rubber or plastic, etc. The actual stiffness of the buffer component 5 may be adjusted by the structure and thickness of the buffer component 5 to adjust the reliability of the fit between the sliding member 42 and the connecting member 2.

[0059] Specifically, the number of the buffer components 5 may include at least two, and at least two buffer components 5 may be arranged at intervals along the axial direction of the connecting member 2 .

[0061] Specifically, one end of the sliding member 42 may be slidably matched with the housing 41 of the sensor 4 , and the other end may be provided with a first slot, and the notch of the first slot may face the connecting member 2 .

[0062] Specifically, the sliding member and the connecting member 2 move synchronously, and the movement directions and strokes of the two members are the same.

[0063] Optionally, a second slot is provided on the connecting member 2; at least a portion of the sliding member 42 is embedded in the second slot; the buffer component 5 is provided between the sliding member 42 and the second slot, and squeezes the outer periphery of the sliding member 42 and the side wall of the second slot respectively to achieve a tight fit between the sliding member 42 and the connecting member 2.

[0064] Specifically, the sliding member 42 is embedded in the second slot on the connecting member 2 , so that the connecting member 2 can protect the sliding member 42 .

[0065] Specifically, a slide groove may be provided on the housing 41; at least a portion of the sliding member 42 may be embedded in the slide groove and slidably connected to the slide groove. Specifically, the extension direction and extension length of the slide groove may be set with reference to the second limiter 12 to ensure that the sliding member 42 and the connecting member 2 move synchronously, so that the sensor 4 can obtain the stroke of the connecting member 2 by detecting the stroke of the sliding member 42, and can also avoid collision between the sliding member 42 and the limiter housing 1, thereby avoiding damage to the sliding member 42 and the limiter housing 1.

[0066] Optionally, the sliding member 42 is detachably connected to the housing 41 , which facilitates the removal and replacement of the sliding member 42 and improves the applicability of the sensor 4 .

[0067] Specifically, the shell 41 and the sliding member 42 may both be made of plastic, which can prevent interference with the measurement signal of the sensor 4 .

[0068] Specifically, the housing 41 can be fixed to the limiting housing 1 by screws, and the specific number of screws can be set according to actual needs. Specifically, at least part of the housing 41 can be embedded in the limiting housing 1, and the housing 41 and the limiting housing 1 can also be connected by a sealing ring to meet the sealing requirements of the accommodating cavity. At least one sealing ring can be provided between the housing 41 and the limiting housing 1, and the specific number can be set according to actual needs.

[0069] Optionally, a receiving groove is provided on the sliding member 42 and / or the connecting member 2; the buffer component 5 is embedded in the receiving groove to improve the reliability of fixing the buffer component 5.

[0070] Specifically, the receiving groove may be an annular groove. The receiving groove may be provided only on the sliding member 42; or, the receiving groove may be provided only on the connecting member 2; or, the receiving groove may be provided on both the sliding member 42 and the connecting member 2.

[0071] Optionally, at least one notch 22 is provided at one end of the connecting member 2, and the notch 22 is used to accommodate the buffer component 5. It is possible to provide an accommodating groove on the connecting member 2, which can improve the reliability of the installation of the buffer component 5.

[0072] Optionally, the steering limiting mechanism may further include a transmission member 3 connected to the wheel; the transmission member 3 is disposed in the limiting housing 1 and is in transmission connection with the connecting member 2 .

[0073] In the embodiment of the utility model, the transmission member 3 is connected to the wheel and the connecting member 2 respectively. In this way, the movement direction of the connecting member 2 can be limited, and then the movement direction of the wheel can be limited by the transmission member 3, thereby improving the reliability of controlling the wheel movement.

[0074] Specifically, during the rotation of the wheel, the transmission member 3 can be driven to move, and the transmission member 3 can drive the connecting member 2 to move. By controlling the movement direction and movement stroke of the connecting member 2, the stroke of the transmission member 3 can be limited to avoid axial over-travel collision of the transmission member 3.

[0075] Specifically, the transmission member 3 is connected to the wheel and the connecting member 2 respectively, and can also change the rotational motion into a linear motion. The transmission member 3 can be a lead screw, and further, the transmission member 3 can be a trapezoidal lead screw to further improve the self-locking performance of the transmission member 3, prevent the transmission member 3 from axial movement when there is no need to drive the wheel to rotate, ensure the high precision and stability of the steering gear, improve the precise control of the wheel steering, and increase the precision and stability of driving.

[0076] Specifically, the axial direction of the transmission member 3 is the same as the sliding direction of the first limit member 21, so as to effectively limit the transmission member 3 to move linearly along its axial direction, so that the transmission member 3 can only generate displacement along its axial direction, thereby avoiding circumferential rotation of the transmission member 3, and thus ensuring the self-locking performance of the transmission member 3.

[0077] Specifically, the connecting member 2 and the transmission member 3 may be fixedly connected, and the connection method may be threaded connection or bonding.

[0078] Specifically, the transmission member 3 is disposed in the limiting housing 1 and can move in the limiting housing 1. Further, one end of the connecting member 2 is slidably connected to the sensor 4, and the other end is connected to the transmission member 3, so that when the transmission member 3 moves along its axial direction, the transmission member 3 can drive the connecting member 2 to move linearly synchronously. The sensor 4 can obtain the displacement of the transmission member 3 by detecting the displacement of the connecting member 2.

[0079] Furthermore, the transmission member 3 can be connected to the wheel. By controlling the displacement of the transmission member 3 along its axial direction, the rotation angle of the wheel can be controlled, and then the rotation amount of the wheel can be effectively monitored and controlled, thereby improving the accuracy and reliability of wheel steering.

[0080] Alternatively, if Figure 1 and Figure 2As shown, a limiting groove 11 is provided in the limiting housing 1; the limiting groove 11 extends along the X direction; the transmission member 3 is provided in the limiting groove 11 and moves in the limiting groove 11 along the X direction.

[0081] In the embodiment of the utility model, a limiting groove 11 is provided in the limiting housing 1 and extends along the X direction, which can improve the reliability and stability of the transmission member 3 moving along the X direction in the limiting housing 1.

[0082] Specifically, the extending direction of the limiting groove 11 is the same as the extending direction of the second limiting member 12, so as to effectively ensure that the transmission member 3 and the connecting member 2 synchronously perform linear reciprocating motion. The transmission member 3 can rotate while performing linear motion, and the connecting member 2 can only perform linear motion.

[0083] Specifically, the second limiting member 12 can be arranged on the inner wall of the limiting groove 11, and the first limiting member 21 can be arranged on the outer periphery of the connecting member 2, which can improve the reliability of the limiting cooperation between the first limiting member 21 and the second limiting member 12.

[0084] Optionally, the connecting member 2 includes a position limiting installation structure 23 , and the position limiting installation structure 23 is suitable for limiting the installation of the connecting member 2 and the transmission member 3 .

[0085] In the embodiment of the utility model, the installation of the connecting member 2 and the transmission member 3 is limited by the limiting installation structure 23, so that the reliability of the assembly between the connecting member 2 and the transmission member 3 can be improved.

[0086] Optionally, the limiting installation structure 23 includes a limiting portion 231 and a connecting portion 232 ; the connecting portion 232 is disposed at one end of the limiting portion 231 away from the first limiting member 21 , the connecting portion 232 is connected to the transmission member 3 , and the limiting portion 231 abuts against the transmission member 3 .

[0087] In the embodiment of the utility model, the connecting portion 232 can play a role of connecting with the transmission member 3, and the limiting portion 231 can play a role of limiting, which can improve the reliability of assembly between the connecting member 2 and the transmission member 3.

[0088] Specifically, the limiting portion 231 is disposed between the connecting portion 232 and the first limiting member 21 , the connecting portion 232 and the limiting portion 231 are disposed at an angle, and the connecting portion 232 and the limiting portion 231 are connected to form a T-shaped structure.

[0089] Specifically, the connection portion 232 can be screwed into the transmission member 3 to achieve installation and fixation between the connection portion 2 and the transmission member 3. After the connection portion 232 is screwed into the transmission member 3, the limiting portion 231 abuts against the transmission member 3, so that the limiting portion 231 can play a limiting role, which can prevent the connection portion 232 from being too long and exceeding the transmission member 3.

[0090] Specifically, the length of the connecting portion 232 may be less than the thickness of the transmission member 3 to prevent the connecting portion 232 from being screwed through the transmission member 3. The transmission member 3 may be provided with a threaded hole, and the connecting portion 232 may be provided with an external thread structure, and the connecting portion 232 may be screwed into the threaded hole.

[0091] Optionally, a cross-sectional area of ​​the limiting portion 231 is greater than a cross-sectional area of ​​the connecting portion 232 , and the limiting portion 231 is used to limit the movement of the connecting portion 232 .

[0092] In the embodiment of the utility model, the cross-sectional area of ​​the limiting portion 231 is larger than the cross-sectional area of ​​the connecting portion 232, so that the limiting portion 231 can limit the movement of the connecting portion 232, thereby avoiding the transitional assembly of the connecting portion 232 and the transmission member 3.

[0093] In the embodiment of the utility model, the connecting member 2 can be a rotating body structure, and the two ends of the connecting member 2 along its axial direction can be respectively assembled with the sensor 4 and the transmission member 3. There is only a sliding connection between the connecting member 2 and the sensor 4, and the limiting fit between the connecting member 2 and the limiting housing 1 can avoid direct friction between the sensor 4 and the limiting housing 1, thereby reducing the wear of the sensor 4 and ensuring the accuracy and function of the sensor 4.

[0094] Specifically, the steering limit mechanism can be applied to the steering gear to limit the transmission member 3 circumferentially to prevent the possibility of extreme jamming, ensure the steering function of the steering gear, avoid failure of the steering gear, and improve the reliability of wheel steering control.

Moreover, the steering limiting mechanism realizes the limitation through the sliding cooperation between the connecting member and the limiting shell, that is, the limitation does not rely on the sensor, which can reduce the friction loss of the sensor, thereby ensuring the sensitivity of the sensor and improving the self-locking reliability of the steering gear.
