DETAILED DESCRIPTION

[0015] The following will be combined with the 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.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0017] Reference Figures 1 to 2 A dragon-shaped aluminum alloy steering knuckle for new energy vehicles, comprising an integrally formed steering knuckle body, the steering knuckle body comprising an upper body portion 1, a middle body portion 2, a bottom body portion 3, and a left tail portion 4;

[0018] The steering knuckle body is shaped like a dragon, with its upper portion curved and featuring top bosses 11 at either end. The bosses span 60mm and contract radially in the direction of demolding, resulting in a demolding angle of approximately 3-5°. The minor diameter is 10mm. The upper portion of the body is partially rectangular, with slots 12 milled and drilled to accommodate the ball stud assembly of the upper control arm. Several triangular weight-reducing grooves 13 are also located on the back of the upper portion, staggered vertically and arranged parallel to each other.

[0019] The central part 2 of the body is provided with a central hub bearing hole 21, which is connected to the hub bearing. The central part 2 of the body is also provided with side holes, which are connected to the brake.

[0020] Two groups of large-taper column bevel feature holes 22 are provided next to the main body base 3. The taper angle of the large-taper column bevel feature holes is 90°, the machined roughness of the taper surface is Ra1.6, and the friction coefficient with the standard parts is 0.6-0.8. Under the axial preload of the ball pin seat, it can prevent the ball pin from rotating axially to ensure that the fastening nut can be tightened. During disassembly, the large taper angle surface can easily disengage the mating surface, making disassembly convenient.

[0021] The left tail portion 4 is a second large taper column inclined surface characteristic hole 23, and its taper angle is 90°, the taper surface machined roughness is Ra1.6, and the friction coefficient with the standard part is 0.6-0.8. Under the axial preload of the ball pin seat, it can prevent the ball pin from rotating axially to ensure that the fastening nut can be tightened. During disassembly, the large taper angle surface can easily disengage the mating surface, making disassembly convenient.

[0022] The benefits of the present invention are that the technical solution ensures that the stress state of the entire connection part meets the vehicle load, and according to the traditional totem design, the top seat boss meets the load-bearing capacity of the ejector rod; the weight-reducing groove is lightweight; the bottom press-fit steel sleeve has a large taper slope to prevent torque attenuation, etc.
