这是一款推土机专用液力变矩器总成，是推土机液力传动系统的核心部件，整体采用高强度铸铁材质，表面喷涂工程机械专用黄漆，具备耐冲击、耐高温、抗疲劳的特性，专为重载恶劣工况设计。
总成集成了泵轮、涡轮、导轮、控制阀组、安全阀等核心组件，能实现发动机动力的柔性传递与扭矩放大，是推土机实现平稳起步、过载保护和工况自适应的关键装置。
该款液力变矩器主要适配山推 SD16/SD22/SD23 系列推土机，同时兼容小松 D60/D65、D85 等同吨位履带式推土机，是国内工程机械设备中应用广泛的液力传动配件。
This is a bulldozer-specific torque converter assembly, the core component of a bulldozer’s hydrodynamic transmission system. Made entirely of high-strength cast iron and coated with construction machinery-specific yellow paint, it features excellent impact resistance, high temperature resistance, and fatigue resistance, specifically designed for heavy-duty and harsh working conditions.
The assembly integrates key components such as the pump impeller, turbine, stator, control valve group, and safety valve. It enables flexible transmission of engine power and torque multiplication, serving as a critical device for smooth starting, overload protection, and operating condition adaptation of the bulldozer.
This torque converter is primarily compatible with Shantui SD16/SD22/SD23 series bulldozers, and also fits equivalent-tonnage tracked bulldozers such as Komatsu D60/D65 and D85. It is a widely used hydrodynamic transmission component in domestic construction machinery equipment.
