Product Details

The axle (also known as axle) is the core load-bearing and transmission component of agricultural machinery equipment, and its design and performance directly affect the operating efficiency, stability and durability of agricultural machinery. Since agricultural machinery is often in harsh environments such as fields, mountains, and mud, and needs to withstand heavy loads, frequent steering and complex power transmission needs, the structure and function of axles need to be optimized in a targeted manner. The following is a detailed explanation from two aspects: application scenarios and advantages:
1. Typical applications of axles in agricultural machinery and equipment
There are many types of agricultural machinery and equipment (such as farming, planting, harvesting, transportation), and the functions of the axle need to adapt to different operation needs, and the main application scenarios include:
1. Tractor (core power equipment)
Tractors are the "power hub" of agricultural machinery, and axles need to meet the triple needs of drive, steering and carrying at the same time:

Drive axle: transmit engine power to the wheels and drive the tractor (especially in low-adhesion scenarios such as muddy fields and slopes, the left and right wheel speed needs to be adjusted through the differential to avoid skidding);
Steering axle: cooperate with the steering wheel to achieve front wheel steering, and some large tractors adopt "four-wheel steering" (both front and rear axles can steer) to reduce the turning radius and adapt to narrow row spacing field operations;
Bearing requirements: bear the weight of the tractor and the weight of suspended agricultural tools (such as plows and rotary tillers) to ensure the stability of the fuselage during operation.
2. Combine harvester (harvesting core equipment)
The weight of the combine harvester (often up to 5-10 tons) and the complex operating environment (wheat field, rice field, corn field), the axle needs to focus on solving the problem of "heavy load + complex terrain adaptation":

Drive axle: requires high torque transmission capacity to drive the harvester forward in straw-covered and muddy fields;
Walking bridge: adopt a wide track design (with large-diameter tires) to disperse the weight of the fuselage and avoid trapping the vehicle (especially when working in rice fields);
Steering Assist: The steering angle can be fine-tuned on the rear axle on some models to reduce the "missed" area during harvest.
3. Planting and fertilizing equipment (e.g., planters, rice transplanters)
This type of equipment needs to ensure the accuracy of the operation (e.g., uniform row spacing and plant spacing), and the axle needs to focus on "smoothness" and "steering flexibility":

Support bridge: carrying precision components such as seeders and seedling boxes to reduce sowing/planting errors caused by bumps;
Steering axle: The small rice transplanter adopts the "front wheel steering + rear wheel following" design, which is suitable for narrow row spacing (such as 30cm) operation in paddy fields and avoids crushing the planted seedlings.
4. Agricultural Machinery Trailer (Transportation Equipment)
For transporting grain, fertilizer or agricultural tools, the axle needs to be centered on "heavy load bearing":

Rigid axles: mostly non-drive axles, which can withstand a transportation weight of 10-20 tons through high-strength steel;
Brake adaptation: Combined with trailer braking systems (such as pneumatic braking) to ensure safety during heavy downhill or road transportation.
5. Special agricultural machinery (such as sugarcane harvester, cotton picker)
For special agricultural machinery for cash crops, the axle needs to be adapted to the special operating environment:

sugarcane land has many slopes and rocks, and the axle needs to strengthen its impact resistance (such as thickening the bridge shell);
Cotton fields need to be designed to prevent entanglement (axle parts are equipped with guards to prevent cotton wool from getting caught in the bearings).
