Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and more specifically, to a steering knuckle that is easy to install. Background Technology

[0002] The steering knuckle, also known as the "steering knuckle," is a crucial component of the automotive steering axle, enabling stable vehicle movement and responsive directional transmission. Its function is to transmit and bear the load from the front of the vehicle, supporting and driving the front wheels to rotate around the kingpin, thus steering the car. The steering knuckle is a key component connecting the wheels and the suspension system, located between the wheels and the axle (or rear axle). The suspension linkage (such as control arms and links) is part of the suspension system, connected at one end to the chassis or subframe, and at the other end to the steering knuckle via a hinge point (such as a ball joint). Traditional steering knuckle installation requires aligning multiple components (such as brake discs, wheel bearings, and suspension linkages) and securing them with multiple bolts. Repeated adjustments to component positions are necessary during installation, making it time-consuming and labor-intensive, thus complicating and inconvenient. Utility Model Content

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0020] This utility model embodiment provides a steering knuckle that is easy to install, combined with Figures 1 to 4 As shown, the steering knuckle body 1 is provided with a connecting arm 5, a positioning pin 3 is provided at the connecting arm 5, and a connecting hole 4 is provided inside the connecting arm 5. The connecting hole 4 is connected to the suspension connecting bracket (not shown) on the vehicle through a connecting bolt 6. The connecting bolt 6 is a self-locking bolt with a self-locking ratchet structure. The positioning pin 3 is a conical structure, and the suspension connecting bracket is provided with a positioning hole.

[0021] Align the positioning hole of the suspension connecting bracket with the tapered positioning pin 3 on the connecting arm 5 and insert it. Due to the tapered structure design of the positioning pin 3, quick alignment can be achieved, ensuring the initial positioning accuracy of the suspension connecting bracket and the steering knuckle body 1. A connecting bolt 6 with a self-locking ratchet structure passes through the connecting hole 4 and is screwed into the threaded hole of the suspension connecting bracket. The self-locking ratchet structure can automatically lock after reaching the preset torque, preventing the bolt from loosening and improving assembly efficiency.

[0022] The steering knuckle body 1 has a wheel hub bearing mounting part 2 in the middle. The inner wall of the wheel hub bearing mounting part 2 is covered with grease 21, which is made of molybdenum disulfide. This grease forms a stable lubricating film under high loads, reducing direct metal-to-metal contact, decreasing frictional resistance during bearing assembly, and improving lubrication performance over long-term use. The end face of the wheel hub bearing mounting part 2 has an annular magnetic positioning ring 22, made of neodymium iron boron (NdFeB). The magnetic positioning ring 22 is embedded inside the end face of the wheel hub bearing mounting part 2. When the wheel hub bearing approaches the wheel hub bearing mounting part 2, the magnetic positioning ring 22 attracts the bearing, automatically aligning it with the mounting position.

[0023] A buffer gap is provided between the outer diameter of the magnetic positioning ring 22 and the inner diameter of the wheel hub bearing mounting part 2. The buffer gap is filled with elastic damping material, which can effectively absorb assembly impact and prevent damage to the magnetic positioning ring 22 caused by hard contact. The elastic damping material is silicone rubber or polyurethane foam, which has high temperature resistance, aging resistance and good cushioning performance.

[0024] The connecting arm 5 and the steering knuckle body 1 are integrally formed and both are made of aluminum alloy. The integral forming process of aluminum alloy for the steering knuckle body 1 and the connecting arm 5 ensures structural strength while reducing overall weight.

[0025] Working principle: Align the positioning hole of the suspension connecting bracket with the tapered positioning pin 3 on the connecting arm 5 and insert it. Due to the tapered structure design of the positioning pin 3, it can achieve rapid self-centering, ensuring the initial positioning accuracy of the suspension connecting bracket and the steering knuckle body 1. The connecting bolt 6 with a self-locking ratchet structure passes through the connecting hole 4 and is screwed into the threaded hole of the suspension connecting bracket. The self-locking ratchet structure can automatically lock after reaching the preset torque, preventing the bolt from loosening and improving assembly efficiency.

[0026] The inner wall of the wheel hub bearing mounting part 2 is provided with grease 21 to reduce frictional resistance during bearing assembly and improve lubrication performance during long-term use. A magnetic positioning ring 22 is provided at the end face of the wheel hub bearing mounting part 2, so that when the wheel hub bearing approaches the wheel hub bearing mounting part 2, the magnetic positioning ring 22 generates an attraction effect, so that the wheel hub bearing automatically aligns with the installation position, making positioning convenient and installation more convenient.

[0027] Compared to existing technologies, the easy-to-install steering knuckle in this invention improves assembly efficiency and positioning accuracy through the combination of tapered positioning pins 3, magnetic positioning rings 22, and self-locking bolts. At the same time, the inclusion of buffer gaps and elastic damping materials enhances the reliability and durability of the structure.
