[0001] The utility model relates to the technical field of steering knuckles, in particular to a high-strength steering knuckle. Background Art

[0002] With the development of science and technology and the progress of the times, the production process of steering knuckles is becoming more and more excellent. The steering knuckle, also known as the "ram's horn", is one of the important parts in the steering axle of a car. It can make the car run stably and sensitively transmit the direction of travel. The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheels to rotate around the kingpin to steer the car.

[0003] The existing steering knuckle is prone to breakage during use due to uneven force and poor strength because the connecting arm has a curved structure. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the existing steering knuckle, which is prone to breakage due to uneven force and poor strength during use due to the curved structure of the connecting arm. A high-strength steering knuckle is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A high-strength steering knuckle, comprising:

[0007] A first connecting seat, a connecting arm is connected to the top of the first connecting seat, and a second connecting seat is welded to the front of the connecting arm, the inner side of the second connecting seat is threadedly connected to a threaded tube, and a sliding groove is provided below the outer wall of the threaded tube, the inner side of the sliding groove is slidably connected to a slider, and a thick abutting rod is fixed to the outer wall of the slider, the other end of the thick abutting rod is inserted with a thin abutting rod, and the thin abutting rod is connected to the thick abutting rod through a spring.

[0008] Preferably, a first lug is connected to the upper portion of the outer wall of the first connecting seat, and a second lug is welded to the lower portion of the outer wall of the first connecting seat.

[0009] Preferably, the front sides of the connecting arm and the first connecting seat are provided with reserved grooves, and the inner side of the abutting thick rod is provided with a placement groove.

[0010] Preferably, both the inner and outer walls of the threaded tube are provided with threaded areas.

[0011] Preferably, the abutting thick rod forms a sliding structure through a slider, a sliding groove and a threaded tube, and the slider is an arc-shaped structure.

[0012] Preferably, the abutting thin rod forms an elastic structure with the abutting thick rod through a spring, and the abutting thin rod forms a sliding structure with the connecting arm through a reserved groove.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0014] 1. In the present invention, by arranging the threaded tube, the second connecting seat, the thick abutting rod and the thin abutting rod, etc., when people connect the rod body to the threaded tube, the threaded tube will initially move downward along the inner side of the second connecting seat until it drives the thick abutting rod and the thin abutting rod to abut against the first connecting seat. When the rod body is working, the force applied to the second connecting seat is switched from a state where the connecting arm bears the force alone to a state where the connecting arm, the first connecting seat and the abutting rod assembly bear the force synchronously. This can effectively reduce the force on the connecting arm, thereby improving the overall strength of the steering knuckle and making it less likely to break. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Reference Figure 1-3A high-strength steering knuckle comprises a first connecting seat 1, a connecting arm 3 is connected to the top of the first connecting seat 1, and a second connecting seat 4 is welded to the front of the connecting arm 3, a threaded tube 7 is threadedly connected to the inner side of the second connecting seat 4, and a slide groove 8 is provided at the bottom of the outer wall of the threaded tube 7, a slider 9 is slidably connected to the inner side of the slide groove 8, and a thick abutting rod 10 is fixed to the outer wall of the slider 9, and a thin abutting rod 13 is inserted into the other end of the thick abutting rod 10, and the thin abutting rod 13 is connected to the thick abutting rod 10 through a spring 12, and the inner and outer walls of the threaded tube 7 are provided with threaded areas. By providing the threaded areas on the inner and outer walls, the rod body connected to the steering knuckle can drive the threaded tube 7 to move downward along the second connecting seat 4 when connecting with the threaded tube 7, thereby driving the thick abutting rod 10 and the thin abutting rod 13 to move downward synchronously and connect with the first connecting seat. When the seat 1 is in contact with the thick rod 10, the thick rod 10 forms a sliding structure through the slider 9, the slide groove 8 and the threaded tube 7, and the slider 9 is an arc-shaped structure. When the threaded tube 7 is driven by the docking rod body, it can perform a spiral downward operation. Therefore, the thick rod 10 needs to be in place, and it slides along the outer side of the slider 9 through the slide groove 8, which can effectively avoid the problem of movement interference. The thin rod 13 forms an elastic structure with the thick rod 10 through the spring 12, and the thin rod 13 forms a sliding structure with the connecting arm 3 through the reserved groove 5. When the thick rod 10 and the thin rod 13 are in contact with the first connecting seat 1, and the second connecting seat 4 is subjected to the force of the docking rod body in the vertical direction, the setting of the spring 12 can effectively buffer the second connecting seat 4 and the first connecting seat 1.

[0022] A first lug 2 is connected to the upper portion of the outer wall of the first connecting seat 1, and a second lug 6 is welded to the lower portion of the outer wall of the first connecting seat 1. The arrangement of the first lug 2 and the second lug 6 facilitates the connection of the steering knuckle with docking parts at multiple angles. A reserved groove 5 is provided on the front of the connecting arm 3 and the first connecting seat 1, and a placement groove 11 is provided on the inner side of the abutting thick rod 10. The arrangement of the reserved groove 5 facilitates the movement of the end of the abutting thin rod 13 along the inner side of the reserved groove 5.

[0023] Working principle: When in use, the staff first installs the front axle of the wheel in the middle slot of the first connecting seat 1, and then threads the docking rod body into the threaded tube 7. Since the inner and outer walls of the threaded tube 7 are both provided with threads, before the docking rod body is connected to the threaded tube 7, it will be affected by the threads of the outer wall of the threaded tube 7 and the threads of the inner wall of the second connecting seat 4, causing the threaded tube 7 to move downward in a spiral, thereby driving the abutting thick rod 10 and the abutting thin rod 13 to move downward synchronously, and perform an abutting operation with the first connecting seat 1, and the end of the abutting thin rod 13 moves to the reserved position. After the inner bottom end of the groove 5 is reached, the docking rod body continues to be rotated to complete the threaded connection between it and the threaded tube 7. Then, the force generated by the docking rod body is applied to the second connecting seat 4 and the threaded tube 7. Through the setting of the spring 12, it can effectively play a buffering role between the second connecting seat 4 and the first connecting seat 1. During this period, the state where the connecting arm 3 is subjected to force alone is switched to a state where the connecting arm 3, the first connecting seat 1 and the abutting rod assembly are subjected to force synchronously. This can effectively reduce the force on the connecting arm 3, thereby improving the overall strength of the steering knuckle and making it less likely to break.

[0024] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
