[0031] Schematic diagram of a steering knuckle for a car.

[0032] refer to Figures 3 to 9 According to a preferred embodiment of the utility model, a steering knuckle for an automobile is as follows: Figure 3 , Figure 4 and Figure 5As shown, the steering knuckle body 10 includes a wheel hub mounting shaft 101, two brake arms 102, a shock absorbing arm 103, a steering arm 104 and a kingpin arm 105. The wheel hub mounting shaft 101 is arranged at one end of the steering knuckle body 10 and is arranged perpendicular to the end surface of the steering knuckle body 10. The brake arm 102, the shock absorbing arm 103, the steering arm 104 and the kingpin arm 105 are arranged at the wheel hub mounting shaft 101. In the circumferential direction of the steering knuckle body 10, the shock absorber arm 103 and the kingpin arm 105 are each provided with a partition groove 1031, a connecting hole 1032 and a tightening hole 1033, the tightening hole 1033 extending from the two side walls of the partition groove 1031 in opposite directions, the connecting hole 1032 passes through the middle section of the partition groove 1031, and the central axis of the connecting hole 1032 is arranged perpendicular to the central axis of the tightening hole 1033.

[0033] It should be noted that when the shock absorber arm 103 is connected to the external automobile shock absorber, assuming that the end of the external automobile shock absorber is an optical axis, and the optical axis passes through the connecting hole 1032, the assembler can make the bolt pass through the tightening hole 1033 from one end of the tightening hole 1033, and tighten the nut at the other end of the tightening hole 1033, thereby making the parts of the shock absorber arm 103 located on both sides of the partition groove 1031 move towards each other, and bring the hole wall of the connecting hole 1032 close to the side of the optical axis, and at a certain moment, the hole wall of the connecting hole 1032 abuts against the side of the optical axis and fastens the optical axis, thereby realizing the connection between the shock absorber arm 103 and the external automobile shock absorber. Obviously, compared with the prior art which has only one connecting hole 1032 with a fixed aperture, the embodiment of the present application separates the connecting hole 1032 by a separating groove 1031, and sets the tightening hole 1033, so as to achieve adjustable aperture of the connecting hole 1032. During installation, the end of the automobile shock absorber is fastened by the hole wall of the connecting hole 1032 which is divided into two parts. The invention is suitable for the installation of automobile shock absorbers with a stepped surface and a threaded portion at the end, and is also suitable for the installation of automobile shock absorbers with an optical axis at the end, and has the advantage of better versatility.

[0034] It should also be noted that in the prior art, Figure 6 As shown, the two side walls of each partition groove 1031 from the notch of the partition groove 1031 to the connecting hole 1032 are both planes with equal spacing, which results in that when the bolt passes through the tightening hole 1033 and the nut is tightened, the parts of the shock absorbing arm 103 located on both sides of the partition groove 1031 move toward each other, as shown in FIG. Figure 7 As shown, when the two side walls at the notch of the partition groove 1031 abut against each other, the two side parts of the shock absorbing arm 103 located at the partition groove 1031 cannot be further moved toward each other, and the adjustable range is small.

[0035] In view of this, in the present utility model, if Figure 5 and Figure 8 As shown, the distance between the two side walls of each partition groove 1031 from the notch of the partition groove 1031 to the connecting hole 1032 gradually decreases. Specifically, the two side walls of the partition groove 1031 each have an inclined surface 10311 .

[0036] It should be noted that, refer to Fig. 9 By gradually reducing the distance between the two side walls of each partition groove 1031 from the notch of the partition groove 1031 to the connecting hole 1032, when the nut is tightened and the parts of the shock absorber arm 103 located on both sides of the partition groove 1031 move toward each other, the parts located on the two side walls of the partition groove 1031 can be bent at a larger angle to further reduce the minimum aperture of the connecting hole 1032, so as to adapt to the automobile shock absorber with a smaller end optical axis diameter.

[0037] Furthermore, in order to facilitate the bending of the parts of the shock absorbing arm 103 located on both sides of the partition groove 1031, as shown in FIG. Figure 5 and Figure 8 As shown, each of the partition grooves 1031 has a material removal hole 10312 at the connection between the side wall and the bottom wall.

[0038] Furthermore, in order to reduce the overall weight of the automotive steering knuckle and cater to the trend of lightweight automotive parts, Figure 4 As shown, the end of the steering knuckle body 10 away from the hub disc mounting shaft 101 has a weight-reducing groove 106 .

[0039] Furthermore, in order to facilitate the installation of the hub disk mounting shaft 101 and the external hub disk, as Figure 3 As shown, the end of the wheel hub mounting shaft 101 away from the steering knuckle body 10 has a first through hole 1011 and a second through hole 1012, the first through hole 1011 and the second through hole 1012 are arranged vertically and are both arranged on the side of the wheel hub mounting shaft 101, and the apertures of the first through hole 1011 and the second through hole 1012 are the same, the first through hole 1011 and the second through hole 1012 are a cross hole, so that the outer wheel hub can be rotated at most 90° to align its threaded hole with the first through hole 1011 or the second through hole 1012.

[0040] Furthermore, if Figure 3 and Figure 4As shown, both sides of the shock absorber arm 103, the kingpin arm 105 and the steering arm 104 are provided with a notch groove 1034. During installation, one end of the external bolt and nut abuts against the bottom wall of the notch groove 1034, thereby making the other end of the external bolt and nut protruding shorter relative to the end face of the shock absorber arm 103, the steering arm 104 or the kingpin arm 105, which helps to reduce the overall size.

[0041] Furthermore, to meet specific installation requirements, such as Figure 3 and Figure 4 As shown, the shock absorbing arm 103 and the kingpin arm 105 are arranged relative to each other, and the shock absorbing arm 103 and the kingpin arm 105 are arranged inclined, and the distance between the shock absorbing arm 103 and the kingpin arm 105 at one end having the connecting hole 1032 is greater than the distance between the shock absorbing arm 103 and the kingpin arm 105 at one end close to the steering knuckle body 10.

[0042] In addition, if Figure 3 and Figure 4 As shown, the two brake arms 102 are located on the same side of the steering knuckle body 10 , and the two brake arms 102 and the steering arm 104 are respectively located on both sides of the shock absorbing arm 103 .

[0043] In summary, the automobile steering knuckle based on the embodiment of the present application is explained, which provides the automobile steering knuckle with advantages such as better versatility.

[0044] It is worth mentioning that in the embodiment of the present application, the automobile steering knuckle has a simple structure, does not involve complex manufacturing processes and expensive materials, and has high economic efficiency. At the same time, for manufacturers, the automobile steering knuckle provided by the present application is easy to produce and has low cost, which is more conducive to controlling production costs and further conducive to product promotion and use.

[0045] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
