[0002] The function of the steering knuckle is to transmit and bear the front load of the car, support and drive the front wheel to rotate around the kingpin to make the car turn; when the car is in motion, it bears variable impact loads. The shock absorber structure is a device to accelerate the attenuation of the vibration of the frame and body to improve the driving smoothness (comfort) of the car. The shock absorber structure is installed in the suspension system of most cars. As a key component in the suspension, the steering knuckle connects the wheel with many load-bearing parts and elastic elements.

[0034] See also Figures 1 to 6The steering knuckle structure provided by the utility model is now described. A steering knuckle structure includes a steering knuckle body 100, the upper end of the steering knuckle body 100 is provided with a connecting portion of a shock absorber 200, the connecting portion includes a first mounting half sleeve 110 and a second mounting half sleeve 120, the first mounting half sleeve 110 and the second mounting half sleeve 120 are relatively buckled to form a mounting hole for sleeved on the outer periphery of the shock absorber 200; the first end of the first mounting half sleeve 110 and the first end of the second mounting half sleeve 120 are inserted and matched along the axial direction of the mounting hole by means of a limiting insertion structure 130, and the second end of the first mounting half sleeve 110 and the second end of the second mounting half sleeve 120 are provided with a locking structure 140.

[0035] Compared with the prior art, the steering knuckle structure provided by the utility model comprises a connection portion of a shock absorber 200 of a steering knuckle body 100 including a first mounting half sleeve 110 and a second mounting half sleeve 120, wherein the first mounting half sleeve 110 and the second mounting half sleeve 120 are relatively buckled to form a mounting hole. A limited position insertion structure 130 is provided at the first end of the first mounting half sleeve 110 and the first end of the second mounting half sleeve 120, and a locking structure 140 is provided at the second end of the first mounting half sleeve 110 and the second end of the second mounting half sleeve 120.

[0036] When the steering knuckle structure provided by the utility model is used to connect the shock absorber 200, the first installation half sleeve 110 is first buckled on one side of the outer periphery of the shock absorber 200, and the second installation half sleeve 120 is buckled on the other side of the outer periphery of the shock absorber 200. At this time, the first installation half sleeve 110 and the second installation half sleeve 120 are arranged in staggered layers in the height direction, and the second installation half sleeve 120 moves along the axial direction of the installation hole toward the first installation half sleeve 110, and the first end of the first installation half sleeve 110 and the first end of the second installation half sleeve 120 are axially plugged and matched by using the limiting plug-in structure 130. At this time, the first installation half sleeve 110 and the second installation half sleeve 120 are located at the same height, and the two are buckled relative to each other and surrounded on the outer periphery of the shock absorber 200, and finally locked by using the locking structure 140 at the second end of the first installation half sleeve 110 and the second end of the second installation half sleeve 120.

[0037] When disassembling the shock absorber 200 on the steering knuckle structure provided by the present invention, firstly unlock the locking structure 140 of the second end of the first mounting half sleeve 110 and the second end of the second mounting half sleeve 120, move the second mounting half sleeve 120 upward along the axial direction of the mounting hole, and axially separate the first end of the second mounting half sleeve 120 from the first end of the first mounting half sleeve 110. Then remove the second mounting half sleeve 120, and the shock absorber 200 can be disassembled from the above-mentioned steering knuckle structure.

[0038] The utility model provides a steering knuckle structure. When installing and disassembling the shock absorber 200, the shock absorber 200 can be assembled and disassembled without axially moving the shock absorber 200, and the operation is simple and convenient.

[0039] It should be noted that the steering knuckle of the suspension is a key component in the steering system of the automobile. It connects the suspension and the steering axle of the vehicle and plays the dual role of transmitting the steering force and supporting the weight of the vehicle. The steering knuckle is usually made of high-strength metal materials, such as cast iron or alloy steel, and is subjected to processes such as heat treatment to improve its performance. The structure of the connection between the shock absorber 200 and the steering knuckle body 100 is a cylinder, which is adapted to the mounting hole formed by the first mounting half sleeve 110 and the second mounting half sleeve 120. The first mounting half sleeve 110 and the second mounting half sleeve 120 are semi-open structures, that is, each mounting half sleeve has half a mounting hole inside, ensuring that the first mounting half sleeve 110 and the second mounting half sleeve 120 can be separated from the shock absorber 200 in a direction perpendicular to the axial direction of the mounting hole, and the shock absorber 200 can be disassembled and assembled without moving the shock absorber 200 along the axial direction of the mounting hole.

[0040] A bearing hole 170 is provided in the middle of the steering knuckle body 100, and the axial direction of the mounting hole formed by the first mounting half sleeve 110 and the second mounting half sleeve 120 is perpendicular to the axial direction of the bearing hole 170. A plurality of weight-reducing grooves 190 are provided on the periphery of the bearing hole 170, which can reduce the weight of the steering knuckle structure itself and conform to the principle of lightweight design of vehicles. At the same time, when the steering knuckle body 100 has two consecutive bolt holes, a stress groove 180 is provided between the two bolt holes, which can reduce the stress generated by the two bolt holes due to processing.

[0041] The first end and the second end are respectively located at two ends of the first installation half sleeve 110 and the second installation half sleeve 120 , and the first end and the second end are interchangeable, and do not affect the normal use of the connection part of the shock absorber 200 .

[0042] See also Figure 5 and Figure 6 The limiting plug-in structure 130 includes a slot 131 and an insert block 132. One of the first mounting half sleeve 110 and the second mounting half sleeve 120 is provided with the slot 131, and the other of the first mounting half sleeve 110 and the second mounting half sleeve 120 is provided with the insert block 132. The slot 131 and the insert block 132 are plug-in-matched along the axial direction of the mounting hole.

[0043] Among them, the slot 131 and the plug block 132 are both arranged in a conformal manner at the first end of the first mounting half sleeve 110 and the first end of the second mounting half sleeve 120, and the slot 131 and the plug block 132 are both arranged along the axial direction of the mounting hole. When the plug block 132 is inserted into the slot 131, the plug block 132 fills the vacant position formed by the slot 131 to constitute a part of the structure of the overall mounting sleeve.

[0044] See also Figure 4There is an installation gap 150 between the second end of the first installation half sleeve 110 and the second end of the second installation half sleeve 120, and an anti-rotation limit plate 210 fixed on the shock absorber 200 is arranged between the installation gap 150.

[0045] After the first installation half sleeve 110 and the second installation half sleeve 120 are completely buckled on the outer periphery of the shock absorber 200, the second end of the first installation half sleeve 110 and the second end of the second installation half sleeve 120 are not completely fitted, and the above-mentioned installation gap 150 exists. It is precisely because of the existence of the above-mentioned installation gap 150 that when the second end of the first installation half sleeve 110 and the second end of the second installation half sleeve 120 are locked and close to each other by using the locking structure 140, the shock absorber 200 can be completely held tightly to ensure the stability of the installation of the shock absorber 200. At the same time, an anti-rotation limit plate 210 is longitudinally welded on the outer end surface of the shock absorber 200. The thickness of the anti-rotation limit plate 210 is less than the width of the installation gap 150. The anti-rotation limit plate 210 is located in the installation gap 150, which can limit the circumferential rotation of the shock absorber 200 and improve the stability of the shock absorber 200 after installation.

[0046] Preferably, the upper part of the second end of the first installation half sleeve 110 and the upper part of the second end of the second installation half sleeve 120 are relatively provided with inclined surfaces, and the two inclined surfaces together form a guide opening 151 at the upper end of the installation gap 150, and the width of the guide opening 151 gradually decreases from top to bottom. In a state where the first installation half sleeve 110 and the second installation half sleeve 120 are not completely separated, the shock absorber 200 can also be installed or removed by axially moving the shock absorber 200. At this time, the above-mentioned guide opening 151 can guide the anti-rotation limit plate 210 to enter the installation gap 150 more smoothly.

[0047] See also Figure 4 The locking structure 140 includes a first connecting sleeve 141, a second connecting sleeve 142 and a connecting bolt 143. The first connecting sleeve 141 is integrally formed at the second end of the first installation half sleeve 110, and the second connecting sleeve 142 is integrally formed at the second end of the second installation half sleeve 120. The first connecting sleeve 141 and the second connecting sleeve 142 are both provided with connecting holes, at least one of the two connecting holes is configured as a threaded hole, and the connecting bolt 143 penetrates the two connecting holes to threadably connect the first connecting sleeve 141 and the second connecting sleeve 142. The inner diameter of the connecting hole is smaller than the outer diameter of the nut end of the connecting bolt 143.

[0048] When one of the two connecting holes is constructed as a threaded hole, a connecting bolt 143 is used to penetrate the two threaded holes, and the connecting hole away from the end of the connecting bolt 143 with the nut is a threaded hole. As the bolt is continuously screwed in, the nut end of the connecting bolt 143 continuously squeezes the second end of one mounting half sleeve close to the second end of the other mounting half sleeve, thereby locking the two mounting half sleeves.

[0049] When both connection holes are threaded holes, the first installation half sleeve 110 and the second installation half sleeve 120 are tightly buckled on the outer periphery of the shock absorber 200, and the connection bolt 143 is threaded through the two threaded holes to achieve the locking of the two installation half sleeves. Figure 3 A connecting frame 160 is provided at the upper end of the steering knuckle body 100, and the first mounting half sleeve 110 is integrally formed at the end of the connecting frame 160. The first mounting half sleeve 110, the connecting frame 160 and the steering knuckle body 100 are all integrally formed. The width of the connecting frame 160 gradually decreases from the side close to the steering knuckle body 100 to the side close to the first mounting half sleeve 110. Under the premise of ensuring the structural strength, the material consumption can be reduced and the cost can be reduced.

[0050] See also Figure 4 and Figure 6 An observation notch 121 is provided at the lower end of the second mounting half sleeve 120. The observation notch 121 is an arc-shaped notch. The observation notch 121 can be used to more intuitively observe whether the shock absorber 200 is assembled in place.

[0051] See also Figure 3 and Figure 5 The upper end surface of the connecting frame 160 is provided with a reinforcing rib 161 along the length direction, and the reinforcing rib 161 is close to one side of the locking structure 140. The reinforcing rib 161 is integrally formed on the upper end surface of the connecting frame 160, and the thickness of the reinforcing rib 161 gradually decreases from the direction close to the first installation half sleeve 110 to the direction away from the first installation half sleeve 110, and the height of the reinforcing rib 161 gradually decreases from the direction close to the first installation half sleeve 110 to the direction away from the first installation half sleeve 110. The reinforcing rib 161 can improve the overall structural strength of the connecting frame 160, and at the same time, the reinforcing rib 161 can increase the effective connection area between the first installation half sleeve 110 and the connecting frame 160, thereby improving the structural strength of the first installation half sleeve 110.

[0052] Preferably, an avoidance groove 162 is provided on the reinforcing rib 161 for avoiding the disassembly and assembly of the connecting bolt 143, so as to avoid the interference between the connecting bolt 143 and the reinforcing rib 161 during the disassembly and assembly process, which makes the disassembly and assembly of the connecting bolt 143 difficult.

[0053] Based on the same inventive concept, the utility model also provides a vehicle, which uses the above-mentioned steering knuckle structure and thus has the same beneficial effects as the above-mentioned steering knuckle structure, which will not be described in detail herein.

[0054] 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 and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
