LT350 tractor drive axle

As a manufacturer of high-power four-wheel-drive tractors, when selecting a drive axle, the main focus is on the following characteristics: load-bearing capacity, transmission reliability, braking stability, availability of a well-established component supply system, stable production volume, a wide product range for all power ranges, and the possibility of customized configuration. The Shandong Lutong LT350 tractor drive axle was developed specifically for 300–350 hp wheeled tractors. It is equipped with high-precision bevel gears produced by Olikon and a scaled-up NGW planetary reduction gear design. After durability testing on a test bench and verification under high-load field conditions, this drive axle has become the optimal component for high-power four-wheel-drive tractors.

LT350 is a drive axle for tractors, developed by Shandong Lutong in accordance with standards for high-power tractors. It is designed for wheeled tractors with a power of 300–350 hp and is specifically created for heavy agricultural work: deep plowing and soil loosening, towing heavy loads, operation in swampy fields, as well as in conditions of high and low temperatures in the field.

Main technical parameters

Main reducer: bevel gear transmission according to the Oerlikon design.

The transmission adopts a conical gear transmission scheme based on the Olicon design, which ensures high gear strength, low operating noise and high transmission efficiency. During continuous operation with high torque, the transmission runs smoothly, power losses are reduced, heating of the entire drivetrain is decreased, the service life of the gears is extended, and the number of failures occurring after equipment sale is reduced.

Wheels: an enlarged-scale NGW planetary gearbox design.

The wheels are equipped with an enlarged-scale NGW planetary gearbox design, which features high load-carrying capacity and structural strength. Under heavy-load and impact-load operation of high-power tractors, the structural stability is improved; it can withstand short-term peak torques generated during plowing and towing, and meets the requirements for intensive continuous operation of high-power agricultural machinery.

Bridge housing: rectangular cast iron casting.

The bridge housing has a rectangular cross-section and is cast from cast iron as a single piece, which ensures high rigidity and great load-bearing capacity. Compared with conventional welded bridge housings, it has higher resistance to deformation; when working under heavy loads and on uneven field surfaces, deformation occurs less often, which allows better protection of the internal transmission components and improves the reliability of the entire equipment.

Brakes: disc.

Standard caliper disc brake, large braking torque, stable and reliable braking. Stable braking response when driving in heavy conditions on downhill slopes and in field conditions ensures the safety of high-power tractors.

Parking brake: Hydraulic caliper disc parking brake

Equipped with a hydraulic clamping disc parking brake, it is easy to operate and locks securely. It locks reliably during long-term parking in the field and on ramps, reducing the risk of slipping and meeting the safety requirements of foreign agricultural machinery regulations.

The LT350 tractor drive axle is suitable for wheeled tractors with 300 to 350 horsepower, which are used for heavy agricultural work such as farmland cultivation, soil preparation, deep loosening, traction, and transportation, and also supports OEM procurement from tractor equipment manufacturers. The LT350 tractor drive axle is the main model in the high-power tractor segment of Lutong's tractor drive axle lineup. Our tractor drive axle product line covers the full power range—from small to high-power. Equipment manufacturers can select models in one go to simplify the supply chain.

Examples of product configurations for major agricultural machinery manufacturers

Our series of drive axles for tractors has been validated through serial installation on vehicles of leading domestic and foreign manufacturers of agricultural machinery:

• In China: we have been steadily supplying products over a long period to such well-known agricultural machinery manufacturers as Xuzhou Kaier. Our cooperation has already lasted for many years, and the products have undergone field tests on vast agricultural lands in China.

• Abroad:We carry out serial deliveries of products for PTZ tractor production projects and have been supplying them to the Russian market for a long time. The products are adapted to operating conditions on agricultural land with a harsh climate, high loads, and a large amount of dust, which allows us to receive repeat orders from foreign agricultural machinery manufacturers. Numerous examples of successful vehicle loading confirm the reliability of Lutong tractor drive axles. You do not need to bear the risks associated with testing a new product on the market.

Guaranteed production capacity and stable supplies

The maximum annual production capacity of the tractor drive axle sector is 20,000 units. With sufficient production capacity reserves, we can fulfill annual long-term orders from equipment manufacturers, support phased production planning, and effectively respond to order growth during peak season in the agricultural machinery industry, as well as ensure the reliable operation of your entire machine. The production plan will not be interrupted due to delays in axle delivery. We have developed and improved a safe storage mechanism for raw materials and have stocked key components such as gears, bearings, and seals in advance to reduce supply risks associated with supply chain fluctuations.

Quality control system

Quality control is carried out at all stages of the production process: from incoming raw material inspection at the factory, sampling inspection of part processing, hardness measurement after heat treatment, and assembly process control to comprehensive testing of finished products. Control points are provided at each stage to ensure traceability of all products. We can provide the manufacturer with a pre-shipment inspection report, as well as documents confirming material quality. In addition, we facilitate third-party expert audits at the customer’s site and on-site inspections of production capacity, which enables compliance with the supplier inspection standards required by the manufacturer and helps ensure successful qualification assessment within the supply chain.
