In addition, during the boring process of the steering knuckle, a left-right reciprocating boring process is generally adopted. The boring machine operator needs to move left-right and change positions at the workstation according to the position of the boring equipment. This has low safety and can easily affect the processing quality of the steering knuckle, resulting in low processing efficiency. Therefore, in response to the above problems, a new energy lightweight racing steering knuckle is proposed. Utility Model Content

DETAILED DESCRIPTION
[0019] See Figure 1-5As shown, the technical solution adopted in this specific embodiment is: it includes an upper support arm mounting part 1, a steering tie rod mounting part 2, a lower support arm mounting part 3, a brake wheel cylinder fixing part 4, a main shaft mounting part 5, a weight reduction hollow position 6, an upper support arm mounting hole 7, a steering tie rod mounting hole 8, a lower support arm mounting hole 9, a brake wheel cylinder fixing hole 11, a main shaft mounting hole 12, and a sealing screw hole 13; the upper support arm mounting part 1, the steering tie rod mounting part 2, the lower support arm mounting part 3, the brake wheel cylinder fixing part 4, and the main shaft mounting part 5 are integrally formed, the upper support arm mounting part 1 is located at the top, and two lower support arm mounting parts 3 corresponding to the upper and lower positions are provided below the upper support arm mounting part 1, the steering tie rod mounting part 2 is located on the right side of the upper arm mounting part 1, and the brake wheel cylinder fixing part 4 is located on the left side of the upper arm mounting portion 1. The space between the two lower arm mounting portions 3 is the main shaft mounting portion 5. A weight-reducing hollow space 6 is provided between the upper arm mounting portion 1 and the upper lower arm mounting portion 3, and between the brake wheel cylinder fixing portion 4 and the main shaft mounting portion 5. An upper arm mounting hole 7 is provided in the middle of the upper arm mounting portion 1. Two steering wheel cylinder mounting holes 8 with corresponding positions and identical structures are provided on the steering rod mounting portion 2. A lower arm mounting hole 9 is provided in the middle of each of the two lower arm mounting portions 3. Two brake wheel cylinder fixing holes 11 with corresponding positions and identical structures are provided on the brake wheel cylinder fixing portion 4. A main shaft mounting hole 12 is provided in the middle of the main shaft mounting portion 5. Four evenly distributed sealing screw holes 13 are provided around the main shaft mounting hole 12.
[0020] Furthermore, the weight-reducing hollow portion 6 between the upper arm mounting portion 1 and the upper lower arm mounting portion 3 is a hollow structure separated by cross-reinforcement ribs, which can reduce the overall weight of the steering knuckle while providing enhanced bending resistance for the steering knuckle and the upper arm mounting portion 1 of the automobile hub suspension.
[0021] Furthermore, the weight-reducing hollow position 6 between the brake cylinder fixing portion 4 and the main shaft mounting portion 5 is a triangular hollow structure, which utilizes the principle that triangle is the most stable to reduce the overall weight of the steering knuckle while providing higher stability for the connection between the brake cylinder fixing portion 4 and the automobile wheel hub brake equipment.
[0022] Furthermore, the upper arm mounting hole 7 and the lower arm mounting hole 9 have the same aperture and the same structure, and are used for the upper and lower corresponding installation of the bicycle wheel hub suspension upper arm and the lower arm, ensuring that the steering knuckle is stable and does not deviate in the working position of the automobile installation.
[0023] Furthermore, the steering rod mounting hole 8 matches the dimensions of the kingpin of the automobile steering mechanism and the steering rod of the boring machine. When the boring machine is used to process an automobile steering knuckle, the machine can be mounted on the boring machine through the steering rod mounting hole 8, allowing the machine to perform circular motion with the steering rod, facilitating the machining operation. When the steering knuckle is installed in the automobile steering mechanism, the steering knuckle 8 is sleeved onto the kingpin through the steering rod mounting hole 8.
[0024] The working principle of the present invention is as follows: a lightweight automobile steering knuckle with an integrally formed structure is adopted. During installation, the upper arm mounting part 1 and the lower arm mounting part 3 on the steering knuckle are respectively installed and connected with the upper and lower shafts in the automobile steering mechanism, and the installation position is fixed by the upper arm mounting hole 7 and the lower arm mounting hole 9. The steering knuckle 8 is sleeved on the kingpin of the automobile steering mechanism through the steering rod mounting hole 8. The brake cylinder fixing part 4 and the brake structure in the automobile steering mechanism are installed and fixed through the brake cylinder fixing hole 11. The main shaft of the automobile steering mechanism passes through the main shaft mounting hole 12, and four bolts pass through the sealing screw holes 13 to fix the wheel hub and the steering knuckle together; when the steering knuckle is processed on a boring machine tool, the two corresponding steering rod mounting holes 8 on the steering rod mounting part 2 are matched with the machine tool steering rod installation to realize that the steering knuckle can make circular motion in the horizontal direction of the boring equipment, replacing the traditional left and right reciprocating motion.
[0025] The main functions of this steering knuckle are to enable wheel steering and to bear the vehicle's weight and various forces. When the driver turns the steering wheel, the force transmitted by the steering system causes the steering knuckle to rotate around the kingpin via the steering rod mounting portion 2, thereby driving the wheels to change direction. When the vehicle turns, the rotation of the steering knuckle enables the wheels to steer left or right according to the driver's intention. As a key hub in the wheel steering action, it converts the steering system's instructions into actual steering action of the wheels. When the vehicle is stationary, the steering knuckle bears part of the vehicle's weight, including the weight of the body, passengers, and cargo, which is transmitted to the steering knuckle via the suspension system. During vehicle travel, the steering knuckle also has to withstand vertical force, braking force, driving force and lateral force from the ground. Therefore, the weight-reducing hollow position 6 in this steering knuckle can not only reduce the weight of the steering knuckle itself, but its cross-reinforcement rib structure and side triangular structure can provide high stability. When the vehicle accelerates, the steering knuckle on the drive wheel has to withstand the driving force from the drive shaft; when the vehicle brakes, the braking force will also be transmitted to the steering knuckle through the braking system; when the vehicle turns, lateral force will act on the steering knuckle, and the steering knuckle has sufficient strength and rigidity to withstand these forces to ensure safe driving of the vehicle.
[0026] Routine maintenance of this steering knuckle focuses on the wear and tear caused by long-term relative motion between the mounting holes and the pins of the vehicle's steering system. Excessive wear can increase wheel steering clearance, affecting the vehicle's steering precision and handling performance. Regularly inspect the steering knuckle for cracks, deformation, and other signs. During vehicle maintenance, professional testing equipment can be used to check wheel alignment parameters to promptly identify any steering knuckle problems. If the steering knuckle is slightly worn, it can be repaired by replacing worn parts (such as bushings). Severe deformation or cracks in the steering knuckle must be replaced promptly to ensure vehicle safety.
[0027] The above description is only used to illustrate the technical solution of the present invention and is not intended to limit it. Other modifications or equivalent substitutions made to the technical solution of the present invention by ordinary technicians in this field should be included in the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
