High Quality Truck Part Dongfeng FAW SHACMAN SINOTRUK HOWO Foton Chassis Part Drive Axle Differential Active Passive Bevel Gears

Gear Type: Spiral bevel gears are typically used to ensure smooth meshing, low noise, and high load-bearing capacity.
Number of Teeth (Z): The number of teeth is usually much greater than that of the driving bevel gear (e.g., 9 teeth on the driving gear and 35 teeth on the driven gear).
Gear Ratio: The ratio of the number of teeth on the driving gear to that on the driven gear determines the vehicle's speed ratio (e.g., 4.11, 4.88, etc.).
Material: High-strength alloy steel, such as 20CrMnTi and 20CrNiMo, is used to withstand extremely high torque and impact loads.
Manufacturing Process: Complex heat treatment processes such as forging, precision machining (hobbing), carburizing, and quenching are employed to ensure surface hardness and core toughness.
