Description

Technical Field

[0001] This utility model relates to the field of vehicle manufacturing technology, specifically a high-performance heavy-duty truck steering knuckle. Background Technology

[0002] The steering knuckle arm, also called a trapezoidal arm, is the last stage of force transmission component in the steering transmission system. The steering knuckle arm is installed on the left and right steering knuckles, and the other end is connected by a ball joint and tie rod. The steering knuckle is the component that ultimately realizes steering.

[0003] For example, the steering knuckle arm of a heavy-duty truck with announcement number "CN218750989U" has a simple structure and low overall weight. It also features a first and second weight-reduction groove, further reducing component weight and contributing to the overall vehicle's lightweight design. However, during heavy-duty truck operation, the steering knuckle arm must withstand significant external forces and vibrations. The first weight-reduction groove may become a stress concentration area, easily leading to arm breakage or deformation, thus reducing the stability and safety of the vehicle's steering system. Utility Model Content

[0004] The purpose of this invention is to solve the problem that during heavy-duty truck operation, the steering knuckle arm needs to withstand large external forces and vibrations, and the first weight-reducing groove may become a stress concentration area, which can easily lead to the breakage or deformation of the connecting arm, reducing the stability and safety of the vehicle steering system. Therefore, a high-performance heavy-duty truck steering knuckle is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-performance heavy-duty truck steering knuckle is designed, including a steering knuckle arm and a boss. The boss is fixedly connected to the upper part of the steering knuckle arm. A reinforcing structure is provided inside the steering knuckle arm. The reinforcing structure includes reinforcing rods. Multiple reinforcing rods are inserted into slots. The slots are all machined on the front side of the steering knuckle arm. A second threaded hole is machined on the rear side of the slots. The second threaded hole and the first threaded hole are both threadedly connected to bolts.

[0007] Preferably, the first threaded hole is machined on both sides of the inner wall of the reinforcing rod.

[0008] Preferably, a first weight-reducing groove is machined in the middle of the inner wall of the steering knuckle arm.

[0009] Preferably, through holes are machined on both sides of the lower part of the inner wall of the steering knuckle arm.

[0010] Preferably, the bottom of the steering knuckle arm is machined with a second weight-reducing groove.

[0011] The present invention proposes a high-performance steering knuckle for heavy-duty trucks, which has the following advantages: by cooperating with the steering knuckle arm and the reinforcing structure, multiple reinforcing rods are placed into the slots, and then multiple bolts are rotated so that the ends of the bolts are screwed into the first threaded hole and the second threaded hole in sequence, thereby fixing multiple reinforcing rods to the steering knuckle arm. This increases the load-bearing capacity of the first weight-reducing groove through the multiple reinforcing rods, which can minimize the risk of steering knuckle arm breakage or deformation, and to a certain extent improve the stability and safety of the steering system of heavy-duty trucks.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] See attached document Figure 1-6 In this embodiment, a high-performance heavy-duty truck steering knuckle includes a steering knuckle arm 1 and a boss 2. The steering knuckle arm 1 is the main structure of the steering knuckle. The boss 2 is fixedly connected to the top of the steering knuckle arm 1. The steering knuckle arm 1 has a reinforcing structure 6 inside. The reinforcing structure 6 includes reinforcing rods 601. The reinforcing rods 601 are made of high-strength alloy steel. Multiple reinforcing rods 601 are inserted into slots 602. The slots 602 are all machined on the front side of the steering knuckle arm 1. The slots 602 are all machined on the rear side of the slots 602. The second threaded holes 604 and the first threaded holes 603 are all threadedly connected to bolts 605.

[0021] The first threaded hole 603 is machined on both sides of the inner wall of the reinforcing rod 601. The first weight-reducing groove 3 is machined in the middle of the inner wall of the steering knuckle arm 1. The through holes 4 are machined on both sides of the lower part of the inner wall of the steering knuckle arm 1. The second weight-reducing groove 5 is machined at the bottom of the steering knuckle arm 1. The first weight-reducing groove 3 and the second weight-reducing groove 5 can reduce the weight of the steering knuckle arm 1.

[0022] Working principle:

[0023] When using high-performance heavy-duty truck steering knuckles:

[0024] The operator places multiple reinforcing rods 601 into the slots 602, and then rotates multiple bolts 605 so that the ends of the bolts 605 are screwed into the first threaded hole 603 and the second threaded hole 604 in sequence, thereby fixing the multiple reinforcing rods 601 onto the steering knuckle arm 1. The reinforcing rods 601 are made of high-strength alloy steel, which has high strength and good fatigue resistance. The multiple reinforcing rods 601 can increase the bearing capacity at the first weight-reducing groove 3, which can minimize the risk of breakage or deformation of the steering knuckle arm 1, and to a certain extent improve the stability and safety of the steering system of heavy trucks.

[0025] After the multiple reinforcing rods 601 are installed, the boss 2 is connected to the cross tie rod under the heavy truck through ball pins, and connected to the left and right steering knuckles under the heavy truck through through holes 4 and fastening bolts. The strength of the steering knuckle arm 1 is increased, so that the steering knuckle can withstand greater steering force and the steering knuckle has higher durability.

[0026] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
