[0002] The steering knuckle, also known as the "steering knuckle," is a crucial component of the automotive steering axle. It enables stable vehicle movement and sensitive directional transmission. The steering knuckle's 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. During vehicle operation, it withstands varying impact loads, therefore requiring high strength.

[0003] As described in patent application CN202322035673.8, an automotive steering knuckle assembly includes a connecting chuck. A connecting arm is fixedly mounted at the top center of the connecting chuck, and a shock absorber connecting frame is fixedly connected to the right end of the connecting arm. Bolt pins are inserted into the upper and lower sides of the interior of the shock absorber connecting frame, and pin rods are inserted into the center of the inner cavity of each bolt pin. A hinge frame is circumferentially fixedly connected to the surface of the connecting block, and fins are mounted on the outer side of each hinge seat. In this automotive steering knuckle assembly, pressing the pin rods compresses the springs and hinge seats, retracting the fins. Then, inserting the bolt pins into the shock absorber connecting frame and loosening the pins allows the fins to tilt under the push of the pressure plate, thus locking the fins onto the surface of the automotive connector. Tightening the fastening head locks the shock absorber connecting frame to the automotive connector, improving the stability of the steering knuckle installation.

[0004] In the above technical solution, the steering knuckle assembly is fixed with a simple snap-on method when installing the ABS sensor. When the vehicle is driven on bumpy roads for a long time, the fixing parts are prone to loosening due to vibration. This can cause the ABS sensor to shift or shake, which may lead to inaccurate signal acquisition, triggering the ABS system fault light, or even affecting the normal operation of the anti-lock braking system, thus posing a safety hazard.

Detailed Implementation

[0015] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0016] like Figure 1 As shown, an automotive steering knuckle assembly includes a steering knuckle body 1. A shock absorber connecting rod 3 is mounted on one side of the upper surface of the steering knuckle body 1, and a lower control arm connecting rod 8 is mounted on the other side of the upper surface of the steering knuckle body 1. A crossbar connecting rod 7 is mounted on the side of the steering knuckle body 1 adjacent to ...

[0017] like Figure 1 As shown, the upper surface of the steering knuckle body 1 is provided with a plurality of bolt holes 2 for fixing the wheel hub bearing, which ensures the stable installation of the wheel hub bearing.

[0018] like Figure 1 As shown, the two brake disc connecting plates 4 are installed opposite each other. The symmetrical structure provides balanced support, making the brake disc installation more stable.

[0019] like Figure 2 , 3As shown in Figures 4 and 5, the positioning component 6 includes a mounting groove 601, which is formed on the upper surface of the steering knuckle body 1. Several sliding rods 602 are slidably mounted inside the mounting groove 601. Each sliding rod 602 has an arc-shaped clamping plate 605 mounted at its lower end. The arc-shaped clamping plates 605 are all disposed inside the through hole 5. The circumferential surface of the sliding rod 602 is provided with a thread 603. A threaded sleeve 604 is sleeved on the middle of the sliding rod 602. The threaded sleeve 604 is engaged with the thread 603. Several threaded grooves 606 are equidistantly formed on the inner surface of the mounting groove 601. A threaded ring 607 is mounted on the lower surface of the threaded sleeve 604. The threaded ring 607 is engaged inside the threaded groove 606. The sensor is passed through the through hole 5, and then all the threaded sleeves 604 are loosened, so that the threaded ring 607 at the lower end of the threaded sleeve 604 is removed from the threaded groove 606.

This structure, through mechanical thread self-locking, greatly enhances the anti-loosening capability, effectively preventing loosening caused by vehicle vibration and ensuring the absolute stability of the ABS sensor position.

[0020] The working principle of this type of automotive steering knuckle assembly: When installing the ABS sensor, first pass the sensor through the through hole 5, then loosen all the threaded sleeves 604, allowing the threaded ring 607 at the lower end of the sleeve 604 to disengage from the threaded groove 606. At this time, the slide rod 602 can slide in the mounting groove 601, causing the lower arc-shaped clamping plate 605 to move outward, thereby expanding the clamping space and facilitating sensor placement. After placing the sensor in the predetermined position, the operator slides the slide rod 602 downward in sequence, pushing the slide rod 602 and the arc-shaped clamping plate 605 towards the sensor body until the arc-shaped clamping plate 605 grips the sensor. Then, by rotating the threaded sleeve 604, the operator screws the threaded ring 607 at the lower end of the sleeve into the threaded groove 606 on the bottom surface of the mounting groove 601, achieving the locking function. This structure, through mechanical thread self-locking, greatly enhances the anti-loosening capability, effectively preventing loosening caused by vehicle vibration and ensuring the absolute stability of the ABS sensor position.
