15 Ton Steering Axle
1. This bridge makes use of a two - stage reduction transmission structure.
2. For the main reduction, equal - height tooth cycloidal bevel gears are implemented. They are characterized by high gear strength, high transmission efficiency and low noise levels.
3. The wheel side adopts an NGW - type planetary reduction transmission mechanism, whose design is both reasonable and compact.
4. Hydraulic power steering allows for flexible operation.
5. Nodular cast iron is used to cast the bridge housing, resulting in good rigidity and a large load - bearing capacity.
6. A closed multi - disc wet brake is applied. With hydraulic pressurization and spring release, it ensures stable braking performance and high safety and reliability.
Introduction:
15 ton steering axle serves as a key transmission device designed for 13 - 16 ton wheeled excavators. It has a two - stage reduction transmission configuration, a hydraulic power - assisted steering arrangement, and an enclosed multi - disc wet braking setup, integrating the three core functions of steering, driving, and braking. Its fundamental function is to convey the power from the transmission to the wheels and turn it into driving force. Moreover, while the equipment is in operation, it ensures the flexibility of steering and the dependability of braking, fully meeting the requirements for heavy - duty operation and high - mobility performance of construction machinery equipment under complex working conditions.
