[0037] The steering arm ball pin mounting hole 7 is provided with a steering arm weight reduction notch 1004 and a shock sleeve mounting hole front right reinforcing rib 2002 between the hub bearing right mounting hole 8, and the back face has a steering arm rear reinforcing rib 2010; wherein the shock sleeve mounting hole front right reinforcing rib 2002 connects the shock sleeve mounting hole 1 and the steering arm ball pin mounting hole 7, and passes through the outside of the hub bearing right mounting hole 8;

[0038] The knuckle body left weight reduction groove 1003 and the knuckle body right weight reduction groove 1005 are arranged between the hub bearing upper mounting hole 9 and the hub bearing left mounting hole 4, the hub bearing right mounting hole 8;

[0039] The back face of the shock sleeve mounting hole 1 is provided with a shock sleeve mounting hole rear weight reduction groove 1008.

[0040] In the embodiment, the wheel hub bearing left mounting hole 4, the wheel hub bearing right mounting hole 8 and the wheel hub bearing upper mounting hole 9 are bolted with the wheel hub bearing.

[0041] In the embodiment, the shock sleeve mounting hole 1 is inserted with the shock sleeve of the chassis shock absorber, and the shock sleeve locking bolt hole 2 is put into the locking bolt and locked.

[0042] In the embodiment, the lower control arm ball pin mounting hole 6 is bolted with the outer end of the lower control arm, and the steering arm ball pin mounting hole 7 is bolted with the outer end of the steering arm.

[0043] In the embodiment, the caliper bracket upper mounting hole 3 and the caliper bracket lower mounting hole 5 are bolted with the brake caliper bracket.

[0044] In the embodiment, the knuckle is assembled with the wheel hub bearing, the shock absorber, the lower control arm, the steering arm and the brake caliper bracket, so as to realize the functions of bearing, steering and shock absorption. The wheel hub bearing is bolted in the wheel hub bearing left mounting hole 4, the wheel hub bearing right mounting hole 8 and the wheel hub bearing upper mounting hole 9. The shock sleeve of the chassis shock absorber is inserted into the shock sleeve mounting hole 1, and the locking bolt is put into the shock sleeve locking bolt hole 2 and locked, so as to connect the knuckle with the shock sleeve. The outer end of the lower control arm is bolted with the lower control arm ball pin mounting hole 6 by using the ball pin. The outer end of the steering arm is bolted with the steering arm ball pin mounting hole 7 by using the ball pin, and then connected with the knuckle. The brake caliper bracket of the automobile is bolted in the caliper bracket upper mounting hole 3 and the caliper bracket lower mounting hole 5.

[0045] In the embodiment, 1. The automobile wheel hub bearing is fixed with the knuckle through the wheel hub bearing left mounting hole 4, the wheel hub bearing right mounting hole 8 and the wheel hub bearing upper mounting hole 9. The back surface is the matching surface of the wheel hub bearing, so the weight reduction can only be realized on the front surface, that is, the knuckle body lower weight reduction groove 1002, the knuckle body left weight reduction groove 1003 and the knuckle body right weight reduction groove 1005. The three weight reduction grooves will not affect the fixation of the wheel hub bearing and the knuckle.

[0046] 2. The shock sleeve is inserted into the shock sleeve mounting hole 1, and the bolt is installed and locked at the shock sleeve locking bolt hole 2, thereby connecting the shock sleeve with the knuckle. The shock sleeve mounting hole 1 requires high stiffness, and since the shock sleeve mounting hole 1 occupies a large space, the weight reduction space is also large. On the front side of the knuckle, since there is the shock sleeve locking bolt hole 2 on the shock sleeve mounting hole 1, the weight reduction space is small. There is only a large weight reduction space on the back side of the shock sleeve mounting hole 1, i.e. the shock sleeve mounting hole rear weight reduction groove 1008. On the front side of the shock sleeve mounting hole 1, the shock sleeve mounting hole front left reinforcing rib 2001 is connected with the hub bearing left mounting hole 4 periphery, and the shock sleeve mounting hole front right reinforcing rib 2002 is connected with the steering arm ball pin mounting hole 7 through the hub bearing right mounting hole 8 periphery; on the back side, the shock sleeve mounting hole rear left reinforcing rib 2009 is connected with the steering arm ball pin mounting hole 7 through the hub bearing right mounting hole 8 periphery; the caliper bracket mounting hole upper reinforcing rib 2005 and the shock sleeve mounting hole rear right reinforcing rib 2008 connect the shock sleeve mounting hole 1 with the caliper bracket upper mounting hole 3. These reinforcing ribs tightly connect the shock sleeve mounting hole 1 with the caliper bracket upper mounting hole 3, the steering arm ball pin mounting hole 7, the hub bearing upper mounting hole 9, etc., thereby greatly strengthening the stiffness of the shock sleeve mounting hole 1 in the vertical, lateral, and forward directions.

[0047] 3. The steering arm is connected with the knuckle through the steering arm ball pin mounting hole 7. The steering arm ball pin mounting hole 7 requires high lateral stiffness, and does not require forward and vertical stiffness, so the shock sleeve mounting hole front right reinforcing rib 2002, the shock sleeve mounting hole rear left reinforcing rib 2009, and the steering arm rear reinforcing rib 2010 can ensure that the lateral stiffness meets the requirements. Further, the steering arm weight reduction gap 1004 can be used for weight reduction.

[0048] 4. The lower control arm is connected with the knuckle through the lower control arm ball pin mounting hole 6. The lower control arm ball pin mounting hole 6 has certain requirements for vertical, forward, and lateral stiffness. On the front side of the lower control arm ball pin mounting hole 6, the lower control arm ball pin hole front right reinforcing rib 2003 is connected with the hub bearing right mounting hole 8, and the lower control arm ball pin hole front left reinforcing rib 2004 is connected with the hub bearing left mounting hole 4; on the back side, the lower control arm mounting hole rear left reinforcing rib 2011 is connected to the hub bearing right mounting hole 8, and the lower control arm mounting hole rear right reinforcing rib 2012 is connected to the hub bearing left mounting hole 4. Due to these four reinforcing ribs, the forward, vertical, and lateral stiffness of the lower control arm ball pin mounting hole 6 is ensured. At the same time, the knuckle body lower weight reduction groove 1002 and the lower control arm mounting hole upper weight reduction groove 1007 can be made on the front side and the back side, respectively, to reduce the weight of the knuckle.

[0049] The upper caliper bracket mounting hole 3 and the lower caliper bracket mounting hole 5 are mainly required for lateral stiffness. The upper caliper bracket mounting hole 3 and the lower caliper bracket mounting hole 5 can be provided with a lower caliper bracket mounting hole lightening groove 1001 and an upper caliper bracket mounting hole lightening groove 1006 between the knuckle and the upper caliper bracket mounting hole 3 and the lower caliper bracket mounting hole 5. In order to ensure the lateral stiffness of the upper caliper bracket mounting hole 3, the upper caliper bracket mounting hole 3 is provided with an upper caliper bracket mounting hole front reinforcing rib 2005 and a lower shock sleeve mounting hole rear right reinforcing rib 2008. The upper caliper bracket mounting hole 3 and the lower caliper bracket mounting hole 5 are provided with a middle caliper bracket mounting hole reinforcing rib 2006, which is convex along the lateral direction with a certain arc, which can further improve the lateral stiffness of the upper caliper bracket mounting hole 3 and the lower caliper bracket mounting hole 5. In order to ensure the lateral stiffness of the lower caliper bracket mounting hole 5, the lower caliper bracket mounting hole 5 is provided with a lower caliper bracket mounting hole front reinforcing rib 2007 and a lower caliper bracket mounting hole rear reinforcing rib 2013 between the lower caliper bracket mounting hole 5 and the lower control arm ball pin mounting hole 6.

[0050] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
