Part 02: Product Advantages

Yuek company independently developed the steering bridge series products, high market visibility, technical achievements and quality have been widely recognized by the market, the main advantages are as follows:

 

(一) Technological Innovation

01.Designed a large steering angle structure to achieve higher maneuverability

Through the optimization of the steering structure and trapezoidal design, the maximum steering angle has been increased by over 10%, effectively reducing the vehicle's turning radius and enhancing maneuverability on narrow roads or corners.

 

02.Developed an integrated steering knuckle and axle body to improve load reliability

We designed a forged alloy steel steering knuckle and a high-strength integrated axle body.  Through CAE optimization, we performed topological optimization on the structural dimensions, achieving higher strength with the lightest possible weight.

 

03.Optimized the design of the steering knuckle structure and trapezoid to enhance steering performance

The unique design of the steering knuckle and trapezoidal structure ensures synchronized movement between the tractor and trailer, reducing friction losses during steering and resulting in a smoother driving experience.

 

04.Incorporated intelligent configurations to ensure functional stability and reliability

We designed an electronic control assistive return mechanism for the steering angle, an electronic steering lock device, a locking electronic control recognition feedback system, and a main pin angle sensor, making steering more reliable and precise, while simplifying operation and enhancing functionality.

 

05.Utilized an integrated processing technique to achieve higher driving stability

By employing a one-piece forged steering knuckle, we ensured the positional accuracy of the main pin hole through single-clamping processing.  The axle body is formed either through integrated casting or welded forging, and the left and right pin holes are machined in a single clamping process, ensuring the parallelism of the main pin holes.  This approach effectively prevents tire shake and sway, achieving stability during high-speed driving.

 

(二) High-Quality Standards

1. Quality Standards

We adopt the highest international standards in the automotive industry, specifically the IATF16949 quality management system, to ensure the stability of our product quality. The steering knuckle and axle assembly are processed using high-precision machining centers, guaranteeing parallelism and perpendicularity at the wheel end, effectively preventing abnormal tire wear and directional drift.

 

2. Testing Standards

We implement a comprehensive research and development testing methodology that includes theoretical analysis, bench testing, and road testing to ensure high reliability of our products. Critical dimensions, such as the steering knuckle and axle assembly, are subjected to coordinate measurement and high-frequency physical and chemical testing to ensure high standards and reliability in steering performance and load-bearing capabilities.

 

3. Durability Standards

The design life adheres to the B10 standard of 1.5 million kilometers, with the axle assembly fatigue life exceeding 800,000 cycles, and a load safety factor of up to 2.5 times. The wheel end can be equipped with maintenance-free hub units, allowing for 3 years or 500,000 kilometers of maintenance-free operation. The main pin is matched with high-frequency quenched maintenance-free polymer bushings, offering long wear resistance and eliminating the need for maintenance.

 

(三) Wide application

The Yuek steering axle series is widely used in multi-axle trailers, ultra-wide and ultra-long cargo transport, all-wheel drive trucks and special vehicles such as low-floor large buses, port AGVs and other vehicles.

 

(四) Economic practicality

Tire cost savings: Poor performance of traditional steering Axles can cause excessive tire friction and wear, and the optimized steering performance of Yuek steering Axles reduces unnecessary tire friction and wear during driving, saving tire costs up to 30% per year for long-distance road transport vehicles.

Reduced maintenance costs: Yuek Steering Axle reduces suspension and frame lateral forces, reduces the risk of frame deformation or cracking, significantly reduces repair and parking time, and saves maintenance costs.

Reduced fuel consumption: The improved steering efficiency and wheel rolling instead of sliding help to reduce fuel consumption, and the actual test can save 1% to 2% fuel use compared to the traditional steering technology, especially in long-distance transportation can significantly reduce economic costs.

 

Parth03: Customer Case

01.Reactive Steering Axle Series

Yuek reactive steering axle is applied to multi-axle low flat trailer, which improves the carrying capacity of the vehicle, improves the cornering ability by 17%, and effectively reduces tire wear.  This improvement enables customers to transport large engineering equipment and defense equipment transport support more efficiently, improving project construction efficiency and transportation safety.
