Description

Technical Field

[0001] This invention relates to the field of vehicle steering system technology, and in particular to a vehicle steering trapezoidal mechanism. Background Technology

[0002] The steering trapezoidal mechanism is an important component of a vehicle's steering system. When a vehicle turns during driving, the steering trapezoidal mechanism causes the wheels at both ends of the axle to deflect at a fixed angle, ensuring that the two steering wheels move in circles with different turning radii during the turn. This results in rolling contact between the tires and the ground, reducing tire wear and improving the vehicle's steering performance.

[0003] In existing technologies, the geometric parameters of steering trapezoidal mechanisms are typically designed using computer simulation. To verify the effectiveness of the simulated parameters in actual use, multiple sets of steering trapezoidal mechanisms with different dimensional parameters are often manufactured during the vehicle verification phase, resulting in significant costs. Furthermore, each replacement of a trapezoidal mechanism during the experiment requires a disassembly and reassembly operation, greatly delaying the experimental progress. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes a steering trapezoidal mechanism for vehicles, so as to achieve adjustable geometric parameters of the steering trapezoidal mechanism, save manufacturing costs, and accelerate the experimental progress.

[0011] According to the present invention, a vehicle steering trapezoidal mechanism is provided, wherein the trapezoidal arm includes an arm support with a guide groove, and the adjusting component is embedded in the guide groove;

[0012] The guide groove penetrates vertically through the vertical side of the arm support and extends along the length of the arm support. The length of the guide groove is at least one-third of the length of the arm support.

[0013] One end of the adjustment component is connected to the steering knuckle, and the other end of the adjustment component is embedded in the guide groove for adjusting the relative position with respect to the guide groove.

[0022] According to the present invention, a vehicle steering trapezoidal mechanism is provided with a locking groove at the end of the steering tie rod. The locking groove extends from the end face to the middle along the axial direction of the steering tie rod, dividing the end of the steering tie rod into two parts that are compressed and can return to their original position, thereby making the diameter of the end of the steering tie rod variable.

[0023] According to the present invention, a vehicle steering trapezoidal mechanism further includes a clamp sleeved on the outer periphery of the steering tie rod for clamping and squeezing the end of the steering tie rod to fasten the hinge to the steering tie rod.

[0040] In the structure of modern vehicles, the steering trapezoidal mechanism is a key component for steering operations. When a vehicle is turning, the steering trapezoidal mechanism ensures that the wheels at both ends of the axle 400 deflect at a fixed angle, allowing the two steering wheels to make circular motions with different turning radii. This achieves rolling contact between the tires and the ground, reduces tire wear, and improves the vehicle's steering performance.

[0041] Existing steering trapezoidal mechanisms are typically designed using computer simulation. First, computer simulations determine the preliminary dimensional parameters of the steering trapezoidal mechanism. Then, manufacturing and vehicle testing are conducted to verify the effectiveness of the steering trapezoidal mechanism with these preliminary dimensional parameters in practical applications. However, to verify the effectiveness of different dimensional parameters, it is usually necessary to manufacture multiple steering trapezoidal mechanisms of different sizes. The manufacture of each steering trapezoidal mechanism requires a significant amount of materials and manpower, resulting in very high design costs.

[0042] Furthermore, each time a new steering trapezoidal mechanism was replaced during the experiment, complex assembly and disassembly operations were required. This not only increased the workload but also significantly delayed the experimental progress, impacting the overall research and development cycle.

[0043] like Figures 1 to 4As shown, in order to facilitate the adjustment of the geometric parameters of the steering trapezoidal mechanism in vehicle testing and to verify the actual effect of the steering trapezoidal mechanism under different dimensional parameters, an embodiment of the present invention introduces a vehicle steering trapezoidal mechanism.

[0044] The steering trapezoidal structure mainly includes: steering knuckle 300, trapezoidal arm 100, and steering tie rod 200.

[0045] Specifically, the steering knuckle 300 is pivotally mounted at the end of the axle 400 for mounting a steering wheel. A trapezoidal arm 100 is inclined relative to the axle 400 and connected at one end to the steering knuckle 300. A steering tie rod 200 is hinged to the end of the trapezoidal arm 100 opposite to the steering knuckle 300.

[0046] Preferably, one end of the trapezoidal arm 100 is fixedly connected to the steering knuckle 300, and the other end of the trapezoidal arm 100 extends toward the vertical plane of the axle 400. Furthermore, the trapezoidal arm 100 extends obliquely over the outer periphery of the axle 400. The steering tie rod 200 is hinged to the other end of the trapezoidal arm 100.

[0047] The steering tie rod 200 is initially parallel to the axle 400. Trapezoidal arms 100 are located at both ends of the steering tie rod 200. The trapezoidal arms 100 are movably connected to the axle 400 via the steering knuckle 300. The parallelism between the steering tie rod 200 and the axle 400, along with the trapezoidal arms 100 at both ends of the axle 400, forms a trapezoidal linkage mechanism.

[0048] An adjustment assembly 110 is provided at the connection between the trapezoidal arm 100 and the steering knuckle 300 for adjusting the relative position of the steering tie rod 200 and the axle 400.

[0049] Specifically, one end of the trapezoidal arm 100 is connected to the steering knuckle 300 via an adjustment assembly 110. The relative position of the trapezoidal arm 100 and the steering knuckle 300 can be adjusted by setting the adjustment assembly 110. For example, by adjusting the front-rear position, left-right position, or up-down position of the trapezoidal arm 100 and the steering knuckle 300, the front-rear distance between the steering tie rod 200 and the axle 400, the length of the steering tie rod 200, or the height of the steering tie rod 200 and the axle 400 can be adjusted accordingly. This, in turn, adjusts the ratio of the deflection angle between the two trapezoidal arms 100 during the swinging process of the steering trapezoidal mechanism composed of them.

[0050] In this embodiment, the steering trapezoidal mechanism can freely adjust its own size parameters through the adjustment component 110, so that a set of steering trapezoidal mechanisms can be used to conveniently verify the effect of steering trapezoidal mechanisms under various size parameters in actual use, which can not only speed up the progress of verification experiments, but also save manufacturing costs.

[0051] like Figure 4 As shown, based on the above embodiments, another embodiment of the present invention introduces a trapezoidal arm 100 that facilitates the installation of the adjustment assembly 110.

[0052] The trapezoidal arm 100 includes an arm support 120 with a guide groove 121. The adjustment component 110 is embedded in the guide groove 121. The guide groove 121 vertically penetrates the vertical side of the arm support 120 and extends along the length of the arm support 120.

[0053] Specifically, the boom support 120 is provided with a guide groove 121 that runs through both sides. The guide groove 121 extends from one end of the boom support 120 in a straight line, and the extension length is at least one-third of the length of the boom support 120. Moreover, one end of the adjustment component 110 is fixedly connected to the steering knuckle 300, and the other end of the adjustment component 110 is embedded in the guide groove 121.

[0054] By adjusting the relative position of the adjusting component 110 and the guide groove 121, the relative position of the arm support 120 and the adjusting component 110 in three mutually perpendicular directions can be adjusted, thereby adjusting the relative position of the trapezoidal arm 100 and the steering knuckle 300, and realizing the adjustment of the dimensional parameters of the steering trapezoidal mechanism.

[0055] This reduces the design and verification costs of the steering trapezoidal mechanism, improves experimental efficiency, and accelerates the research and development process. It also enhances the overall performance of the vehicle steering system, ensuring vehicle stability and safety under various driving conditions.

[0056] Based on the above embodiments, in another embodiment of the present invention, an adjustment component 110 disposed in a steering trapezoidal mechanism is introduced.

[0057] The adjusting assembly 110 includes a mounting block 111 and an adjusting plate 112. Specifically, the mounting block 111 is embedded in the guide groove 121 and has a gap between it and the side wall of the guide groove 121. Correspondingly, the adjusting plate 112 is placed in the gap between the mounting block 111 and the guide groove 121. When adjusting the size of the steering trapezoidal mechanism, the relative position of the arm support 120 and the adjusting assembly 110 can be adjusted by adjusting the number of adjusting plates 112 on both sides of the mounting block 111 in the same direction.

[0058] For example, the adjusting plate 112 includes: a front-rear adjusting plate, a vertical adjusting plate, and a left-right adjusting plate. In addition, the mounting block 111 has two through holes. The steering knuckle 300 has internally threaded holes that mate with the through holes. Bolts can pass through the through holes and connect to the internally threaded holes of the steering knuckle 300 to fix the trapezoidal arm 100 to the steering knuckle 300. The left-right adjusting plates have through holes corresponding to the through holes of the mounting block 111. Bolts pass through the left-right adjusting plates and the mounting block 111 to ensure that the left-right adjusting plates move together with the mounting block 111. Furthermore, the left and right sides of the trapezoidal arm 100 are respectively provided with left-right adjusting plates, which clamp and fix it to the steering knuckle 300.

[0059] In the longitudinal direction, the two ends of the mounting block 111 have gaps with the guide groove 121 and are padded with front and rear adjustment plates. The trapezoidal arm 100 can be moved rearward relative to the steering knuckle 300 by reducing the front and rear adjustment plates at the front end of the mounting block 111 and increasing the front and rear adjustment plates at the rear end of the mounting block 111, thereby reducing the distance between the steering tie rod 200 and the axle 400.

[0060] Alternatively, in the vertical direction, the two ends of the mounting block 111 have gaps with the guide groove 121 and are padded with vertical adjustment plates. The trapezoidal arm 100 can be moved down relative to the steering knuckle 300 by reducing the vertical adjustment plate at the upper end of the mounting block 111 and increasing the vertical adjustment plate at the lower end of the mounting block 111, thereby reducing the height of the steering tie rod 200 relative to the axle 400.

[0061] In this embodiment, the length or deflection angle of the steering trapezoidal mechanism in the experiment can be adjusted by adjusting component 110. Geometric parameters can be quickly adjusted without replacing the entire mechanism, saving assembly and disassembly time. Furthermore, tests are conducted on steering trapezoidal mechanisms with different dimensional parameters to verify the impact of the steering trapezoidal arm 100 on tire wear, steering accuracy, and other aspects during actual vehicle operation, in order to more accurately evaluate the effects of different parameters.

[0062] Based on the above embodiments, in another embodiment of the present invention, in order to enable the steering tie rod 200 to connect two trapezoidal arms 100 with different spacings and adapt to the characteristics of changes in the dimensional parameters of the steering trapezoidal mechanism, a connection structure between the trapezoidal arm 100 and the steering tie rod 200 is introduced.

[0063] The arm support 120 has a tapered hole 122 at the other end opposite to the guide groove 121. The central axis of the tapered hole 122 is perpendicular to the direction in which the guide groove 121 passes through the arm support 120, so as to facilitate the installation and removal of the steering tie rod 200.

[0064] Specifically, the steering tie rod 200 and the boom support 120 are rotatably connected by a hinge 210. The hinge 210 is mounted on the end of the steering tie rod 200. Furthermore, one end of the hinge 210 is aligned with the central axis of the tapered hole 122.

[0065] Based on the above embodiments, another embodiment of the present invention introduces a vehicle steering trapezoidal mechanism.

[0066] like Figure 3 As shown, the hinge 210 is provided with a tapered pin and a threaded pin rotatably connected by a spherical end. The tapered pin extends vertically and is aligned with the central axis of the tapered hole 122. The threaded pin extends horizontally and is aligned with the central axis of the steering tie rod 200.

[0067] In addition, both ends of the steering tie rod 200 are provided with internal thread structures. The two internal thread structures have opposite directions of rotation. The threaded pin has an external thread structure corresponding to the direction of rotation of the internal thread structures.

[0068] Thus, when adjusting the size of the steering trapezoidal mechanism during the experiment, the distance between the two trapezoidal arms 100 can be adjusted by rotating the steering tie rod 200, so that steering trapezoidal mechanisms with different size parameters can be replaced in a short time, reducing the time for assembly and disassembly.

[0069] like Figure 2 and Figure 3 As shown, based on the above embodiments, in order to prevent the steering tie rod 200 from becoming loose from the hinge 210 during use, another embodiment of the present invention introduces a steering tie rod 200 with an anti-loosening structure.

[0070] The steering tie rod 200 has a locking groove 220 at its end. The locking groove 220 extends along the axial direction of the steering tie rod 200 from its end face to the middle of the steering tie rod 200, dividing the end of the steering tie rod 200 into two parts.

[0071] Specifically, the locking groove 220 divides the end of the tie rod into two parts that can be pressed together and can return to their original position, thereby making the diameter of the end of the steering tie rod 200 variable. When the end of the steering tie rod 200 is subjected to a clamping force, the internal thread structure of the steering tie rod 200 can reduce its diameter due to the closing of the end, locking it with the threaded pin.

[0072] Furthermore, the steering trapezoidal mechanism also includes a clamp. The clamp is sleeved on the outer periphery of the steering tie rod 200 and is used to clamp and squeeze the end of the steering tie rod 200 to fasten the hinge 210 to the steering tie rod 200.

[0073] Based on the above embodiments, another embodiment of the present invention introduces a vehicle steering trapezoidal mechanism.

[0074] The adjusting plate 112 includes front and rear adjusting plates. The mounting block 111 is provided with the front and rear adjusting plates in the gap between the two end faces of the arm support 120 in the length direction and the side wall of the guide groove 121, respectively, for adjusting the relative position of the arm support 120 and the adjusting assembly 110 in the length direction of the arm support 120.

[0075] Furthermore, the arm support 120 is provided with a fastening threaded hole 123, which extends from the end face of the arm support 120 to the guide groove 121 along the length direction of the arm support 120, and can be used to install bolts to abut against the front and rear adjustment plates.

[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

[0077] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
