WZL130 steering axle

Product overview

Our WZL130 steering axle is specifically designed for wheeled backhoe loaders with a lifting capacity of 10-12 tons. It is a high-performance axle that integrates drive and steering functions. This steering axle features a long track, a high load capacity, and high input torque, significantly improving the stability of the entire machine during excavation work, effectively reducing the risk of rollover, and ensuring the safety of personnel and equipment.

The front and rear axles feature a high-quality, universal design, and all other components are matched except for the opposite direction of flange rotation. This design significantly simplifies after-sales service and spare parts management, significantly reducing inventory and maintenance cycle costs for the user. At the same time, the front and rear axles feature steering functions, reducing the turning radius and ensuring the maneuverability of the entire machine in tight spaces.

Product Features

1.Strong bridge shell, strong cornerstone:

The WZL130 steering axle is fully optimized for heavy-duty operation. The axle housing is made of high-strength cast steel and has undergone orthodontic treatment. Its rectangular cross-section provides superior bending and torsional resistance, high rigidity, and high load-bearing capacity. Whether it's the enormous impact of frequent starting and braking of the entire machine or the reactive force transmitted to the axle housing during bucket operation, it can easily handle it, effectively eliminating downtime caused by fatigue damage and ensuring uninterrupted equipment operation.

2.Hydraulic disc brake, safe and effective:

Compared with traditional drum braking, the use of a hydraulic disc brake offers advantages such as fast response, large braking torque, and lighter overall weight, helping to reduce axle weight. The open structure of the WZL130 steering axle has excellent heat dissipation performance, effectively preventing thermal decay during frequent braking and perfectly matching the high-frequency braking performance of backhoe loaders. The brake discs and friction linings are made of high-quality wear-resistant materials with low wear loss and long replacement cycles, significantly reducing operating costs for users.

3.Two-stage braking, high cross-country ability:

Steering axisThe entire machine utilizes a two-stage braking system with a wide gear ratio range, which not only meets the requirements of low-speed, heavy-duty excavation operations to ensure strong traction, but also addresses the high-speed requirements of high-speed transitions. The main drive utilizes high-precision hyperboloid gears, which boast high transmission efficiency and low noise. By optimizing the gearbox design, the vertical size of the main gearbox housing is effectively reduced to ensure strength, significantly increasing the height of the drive axle center section from the ground and improving the overall vehicle's off-road performance in challenging road conditions. The wheel section is equipped with a sophisticated and reliable planetary braking mechanism, featuring a compact design and efficient transmission.

4.Multi-mode steering, flexible maneuverability：

WZL130 steering axleThe machine is equipped with a centrally mounted, dual-acting steering cylinder that is lightweight and responsive. Various hydraulic circuits allow the axle to operate in four modes: front-wheel steering, rear-wheel steering, four-wheel steering, and corner steering, significantly increasing the operational flexibility and maneuverability of the entire machine in narrow fields or difficult terrain.

5. Thanks to direct supplies from manufacturers, prices for steering axles are more competitive:

As a professional manufacturer, we have established a complete production chain, from raw material testing, precision machining of parts and components, to assembly and sales of the entire axle. By eliminating intermediate price differences in the trade link, we can provide our customers with greater cost reduction opportunities. Meanwhile, an integrated production management system effectively controls production costs while ensuring high quality, giving our steering axles a very favorable price advantage in the market.

Product Application

The WZL130 steering axle was born from in-depth technical dialogue with equipment manufacturers. As a company with over 30 years of drive axle research and development, we know that each new product development lives up to customer trust and expectations. At the time, the equipment manufacturer urgently needed an axle that would match its new generation of 10-ton products, which required high load-bearing capacity, multi-steering, and ease of maintenance. Upon receiving the request, our technical team responded quickly, combining years of accumulated operating data and design experience, and completed a preliminary design plan in just a few weeks.

Once the samples were manufactured, we didn't rush delivery, but rather underwent a rigorous validation process. First, we conducted complex lab fatigue tests, simulating loads far exceeding actual operating conditions. Then, we carried out small batch loading and field testing. Throughout the entire testing cycle, our engineers were constantly on-site, recording all key data and addressing even the slightest concerns. This rigorous, almost "harsh," approach significantly reduces the risk of initial product application and eliminates lengthy commissioning cycles for the manufacturer.

Today, this steering shaft is used in various models from many renowned manufacturers, including Shandong Weimeng, Qingzhou Huizhong, Weifang Boding, Laizhou Julang, and others. It is an equivalent to Chinese-made backhoe loaders and is exported to Russia, Belarus, Southeast Asia, and other regions. It has withstood testing in a variety of conditions—from extremely cold to hot and humid, from mines to agricultural fields—and has earned high praise from many equipment manufacturers for its superior reliability. It is a powerful partner for them in expanding their overseas markets.

Verification system

Bench testing of this product utilizes the best capabilities of national laboratories and uses test procedures that far exceed industry standards. To fully ensure the product's reliability and durability under the most severe conditions, the test plan specifically simulates conditions more extreme than actual operation. This not only reflects stringent performance testing, but also effectively fulfills customer commitments.

As part of the bench testing, a special gear fatigue test was carried out, which mainly tested the ability of the drive axle assembly to maintain stable power under extreme high torque and high speed conditions. The test uses a high load mode, and the final torque value is significantly higher than the rated value, which can accurately test the reliability and economy of the gear system.

Intelligent manufacturing system

The company has installed intelligent production lines such as automatic welding lines, intelligent production lines for planetary gear frames, intelligent production lines for main gear housings, intelligent production lines for differential housings, and intelligent production lines for levers and axle housings.

Professional technical support

The company has a professional foreign trade team that can communicate with customers to help them accurately select the right model. Under specific operating conditions, the foreign trade department can coordinate the technical team to conduct online or offline meetings with customers, gaining a detailed understanding of operating conditions, load characteristics, and performance requirements. They can also provide recommendations on drive axle configurations and even custom designs to ensure the product fully meets customer requirements and is fully adapted to real-world operating conditions.
