WZL155 steering drive axle

The WZL155 steering drive axle is a high-quality wet-drive front steering axle specifically developed by Shandong Lutong Heavy Industry for 15-ton wheeled excavators.It is one of the core components of construction machinery transmission and is a main product in our series of wet-drive front axles.This type of front axle with wet steering provides flexible steering, low-noise and high-efficiency transmission, as well as all-weather braking on wet roads.It is specially optimized for front-wheel-drive wheeled excavators.It is suitable for equipment selection by various manufacturers of 15-ton wheeled excavators.both domestically and abroad, and at the same time complies with the export standards of Russia, India, and Central Asia.WZL155 is a special front steer axle with wet drive for earth excavation, and the rigid rear axle of the same load capacity WGL155 forms a complete two-axle support system with wet drive.All axles are equipped with high-quality wet brake designs, and the overall technical level far exceeds traditional axles with dry drive systems.the preferred solution for high-quality undercarriages for medium and large wheeled excavators.

Main technical parameters

Advantages of the WZL155 steering drive axle main product

1. Aolikang contour bevel gear with main reduction, steering transmission, low noise and high efficiency

The main reducer is equipped with imported standard Aolikang bevel gears and other helical gears with high teeth, which have a large meshing area and significantly improved bending strength; the transmission process is characterized by low vibration, low operating noise, and higher transmission efficiency, which ensures that the power of the entire machine does not decrease during continuous mining and frequent steering operations, thereby improving the operating efficiency of the entire machine.

2. Fully enclosed wet braking on the wheel side, linearly stable steering braking

The standard configuration includes high-quality wet-drive wheel brakes, which are the primary safety system of the excavator’s front axle, providing high braking torque and smooth transmission. The fully sealed design isolates dirt, dust, and rainwater from the construction site, and also prevents brake overheating when descending slopes and navigating complex turns, thereby avoiding steering wheel sideslip and brake failure, and adapting the steering to harsh operating conditions in urban environments, mines, and agricultural fields.

3. The four-wheel planetary drive decelerates, and the impact load on the steering is distributed evenly

The wheel-side braking system is optimized for the impact conditions on the steering wheel during excavation, and a four-wheel planetary braking system is adopted; the instantaneous impact load generated during excavation and steering switching is evenly distributed across multiple sets of planetary gears, in order to avoid the destruction of one-sided gears during excavation. front axle, which significantly reduces the failure rate of the axle under various operating conditions and improves durability during frequent excavation work with 15-ton wheels.

4. Integrated overall design of the slewing frame, low center of gravity of the front axle to improve steering stability.

The exclusive overall slewing structure is adapted for the front steering axle, which effectively lowers the center of gravity of the wheeled excavator machine, and the probability of body tipping is significantly reduced when the machine turns in place, climbs and turns around, and performs excavation under full load. The control safety of the entire machine is improved. The reinforced front chassis structure can be used as the main distinguishing feature of the entire machine at the main engine manufacturing plant.

5. Modular integrated design, flexible and adjustable front axle installation distance, suitable for various 15-ton wheeled excavator chassis.

The front axle with wet steering has a standardized modular design, and the dimensions of the front flange and suspension allow for flexible adjustment. Equipment manufacturers do not need to extensively modify the chassis of the entire machine, and it can quickly match various brands of 15-ton wheeled excavators, reducing the time for research and development of new machines, shortening the prototype vehicle testing cycle, and lowering the cost of customized transformation for the manufacturer.

6. Precise adaptation to the front axle of a 15-ton wheeled excavator 

The torque, load, steering wheel angle, and braking parameters of the WZL155 front axle with wet steering are fully adapted to the operating conditions of a 15-ton wheeled excavator and can be adapted to the same equipment of the same load capacity.

Adaptation to application scenarios

Terminal construction conditions

Earthwork in urban pipeline networks, road repair and soil crushing, earthwork in foundation pits, auxiliary reloading operations in open-pit mining areas, dredging of agricultural land for water resource conservation and reclamation of wasteland; for wheeled operations, frequent in-place turns and operation on small construction sites, the WZL155 front axle with wet steering ensures stable operation. It delivers power and braking force to ensure high equipment attendance.

The strength of the enterprise Shandong Lutong

Shandong Lutong Company is located in Feicheng, Tai'an, Shandong Province. It specializes in the research, development, and production of a full range of leading axles for construction, mining, and agricultural machinery. It is a national high-tech enterprise. It has its own intelligent manufacturing workshop, a complete set of imported precision gear processing equipment, and a full-fledged laboratory for strength testing of axles. The annual production volume of various types of leading axles for construction machinery for wet and dry cleaning is more than 50,000 units. All new products have undergone tens of thousands of hours of full-load operation, soaking in mud, and simulation tests at high and low temperatures; the entire process passes through multiple levels of quality control, and the quality meets world standards for leading axles of construction machinery.

Support for cooperation and approval from global equipment manufacturers

More than ten years of experience supporting stationary points at the original factory, wholesale supplies to first-tier construction machinery manufacturers at home and abroad.：

Domestic leaders: SANY, XCMG, Shantui, LiuGong, Lovol, Yingxuan

Export clients: Russia, PZT, Amkodor, UMG

Export client from South Asia: ACE, India.

All cooperating equipment manufacturers have undergone rigorous supplier inspections and established a durability verification system for drive axles, and over many years have proven themselves to be excellent parts suppliers; they jointly develop new machine tools, supply thousands of units in batches every month, have global export supply capabilities, and verify the operation of wet-drive drive axles at terminals around the world. The failure rate is significantly lower than the industry average.

The main reason why equipment manufacturers chose the WZL155 wet steering front axle

1. Exclusive configuration of front steering parameters when digging with a 15-ton wheel, high-quality braking on wet roads, different from the low-cost dry steering axle, improve the positioning of the entire machine;

2. High-precision Aolikang transmission combined with planetary reduction, frequent steering operation, wear resistance and durability reduce the after-sales service cost of the three-component terminal for equipment manufacturers;

3. The overall low center of gravity span improves steering safety and creates a special advertising effect for the main machine.;

4. Modular and adjustable installation dimensions, rapid adaptation to various wheeled excavator chassis reduce the commissioning cycle for new machines.;

5. The source manufacturer directly supplies the steering axle for wet construction machinery, supports wholesale supply in accordance with annual OEM standards, and the price and delivery terms are stable and controllable.;

6. It can be used with the WGL155 rigid rear axle to create a complete set of axle assemblies, and the front and rear drive axles of the wheeled excavator can be installed simultaneously, which simplifies the procurement process.
