Drive axle of cold recycler

Introduction:

The LZ23 cold recycler drive axle is a powerful auxiliary transmission component independently developed and mass-produced by Shandong Lutong Heavy Industry for large-scale in-situ cold recycling road equipment. The cold road recycling process involves high loads, strong impacts, and frequent changes in working conditions. The equipment must perform travel adjustment, road milling, old material recycling, and mixing operations simultaneously. Strict standards are set for the drive axle’s load-bearing capacity, transmission stability, braking safety, and steering adaptability. Drawing on years of research and development experience in engineering equipment axles, the Shandong Lutong engineering team carried out specialized optimization of all structural elements of the LZ23 cold recycler drive axle for the harsh operating conditions of cold recycling equipment, fully solving the vulnerability of traditional support axle transmission, insufficient braking torque, weak axle structure rigidity, poor host adaptability, and other industry pain points.

About Shandong Lutong - a reliable axle supplier for global equipment manufacturers

Shandong Lutong Company, located in Feicheng, Tai'an, Shandong Province, is a high-tech manufacturing plant specializing in the research and development of leading axles with enhanced off-road mobility, intelligent manufacturing, and global OEM support. automated CNC production line. The product lineup includes loader drive axles, grader drive axles, drilling equipment drive axles, and a full range of drive axles for refrigeration regenerators. The company has long been offering serial standardized axles, custom non-standard developments, neutral manufacturers, multilingual technical drawings, and comprehensive remote after-sales service integrated support services for large, medium, and small construction machinery manufacturers around the world, such as Russia, India, Central Asia, and Turkey. .

Six main structural advantages of the LZ23 cold recycler's drive axle

2.1 Three-stage transmission system with speed reduction, stable and reliable output power

The three-stage layer-by-layer speed reduction design allows the impact torque during milling to be distributed across layers, avoiding overload and damage to the gear; the equipment starts, stops, and switches without interruption, effectively protecting the hydraulic and power systems of the entire machine.

2.2 Two-speed gearbox housing, engine input interface with multiple specifications, high adaptability to the host machine

Dual transmissions can be switched to heavy-duty / rapid transition operating mode, and the multi-spec engine interface can work with all types of hydraulic motors without replacing the axle, which is suitable for the full range of light and heavy cold recycling equipment, reducing the development cycle for equipment manufacturers.

2.3 Gleason arc bevel gear main reducer, high efficiency, low noise, durability

Gleason arc teeth have a large meshing area, transmission efficiency over 96%, low operating vibration and noise, meeting European and American requirements for noise levels on construction sites; the gears are carburized and hardened, wear-resistant and fatigue-resistant, significantly reducing maintenance frequency.

2.4 NGW planetary braking mechanism on the wheel side, compact design and easy maintenance

The advanced NGW planetary wheel side braking mechanism ensures high torque transmission and reduces the load on the central transmission; the modular sealed design is dustproof and waterproof, easy to disassemble, assemble, and repair, and is suitable for operation in dusty, dirty, and harsh conditions on construction sites.

2.5 The entire axle housing is made of cast steel, which possesses high rigidity, impact resistance, and high load-bearing capacity.

The integrated cast steel frame has greater resistance to torsion and impact than a welded axle housing, and it is not easily deformed or cracked on bumpy roads under heavy-duty operating conditions, which eliminates safety hazards such as oil spills and gear displacement.

2.6 Built-in drum-type drive parking brake, sufficient braking force, safer operation on ramps

The integrated drum brake combines vehicle driving control and parking braking, features a large friction area, sufficient instantaneous braking torque, stable operation under high-temperature braking conditions, and eliminates the need for additional parking devices.

Product application scenarios

This steering drive axle is specially developed for on-site cold regeneration equipment and is widely adapted for various old road maintenance and reconstruction projects around the world:

1. On-site cold regeneration of old asphalt concrete pavement on national and provincial highways;

2. Urban municipal road reconstruction projects, county and township rural road reconstruction and pavement restoration projects;

3. Damaged and restored old road surfaces in parking lots, industrial parks, and port logistics parks;

4. All low-speed and heavy engineering equipment for road maintenance that requires integrated steering, motion control, and braking functions.

The main reason why global manufacturers choose the Shandong Lutong LZ23 Drive Axle for Cold Recyclers

4.1 Advantages in product performance

All structural designs of the steering drive axles of the LZ23 cold recycler fully meet the requirements for cold recycler operation under high load, and the six main technical advantages include transmission operation, bearings, component adaptation, and braking in all dimensions. Compared with general-purpose steering drive axles available on the market, the whole machine has a lower failure rate, a longer service life, and higher adaptability to complex structural conditions, which can directly enhance the market competitiveness of your cold recycling equipment.

4.2 Direct delivery from the manufacturer, customized development upon request

We do not allow intermediaries to raise prices and provide factory reserve prices for large-scale orders from equipment manufacturers, effectively reducing procurement costs; we can make customized modifications and produce trial production according to the customer’s drawings, tonnage, installation dimensions, and gear ratio requirements, and flexibly coordinate various equipment development plans.

4.3 The automated production line is stable and mass-produced, and the delivery cycle is controllable.

The factory is equipped with a complete set of automated CNC finishing equipment, produces thousands of complete sets of drive axles per month, stocks raw materials in advance for cast steel production, aluminum alloy gears, and brake system components, eliminates raw material shortages and delivery delays, and stably carries out continuous large-scale orders from equipment manufacturers around the world.

4.4 Multilingual global support services, full technical support throughout the process

Both large OEM manufacturers and regional small and medium-sized equipment manufacturers can enjoy equal and impeccable services for pre-sales selection, drawing coordination, and after-sales remote support; bilingual teams proficient in English and Russian respond to inquiries, technical consultations, and application samples within 24 hours, supporting complete parameter tables, 2D/3D drawings, installation and maintenance manuals.
