Trade Information

A hydrodynamic torque converter is the core component of a construction machinery hydro-mechanical drivetrain, installed between the engine and the transmission, using Automatic Transmission Fluid (ATF) as the working medium to achieve flexible power transfer. Unlike traditional mechanical clutches, a torque converter features automatic continuously variable transmission—it automatically adjusts output torque and speed according to external resistance, fully utilizing engine power while protecting drivetrain components and the engine .

Product characteristics of the YJ315X-series torque converter:

  • Basic structure: The YJ315X is a single-stage three-element torque converter, composed of three core components—impeller (pump wheel), turbine, and stator—with a 315 mm torus diameter, directly connected to the engine, flange output, and three PTO ports .

  • Performance parameters: Matches SAE3# flywheel housing, stall torque ratio K0 = 2.86, maximum efficiency ηmax = 0.812, zero-speed converter torque MBg0 = 68.27, high-efficiency-zone converter torque MBgη = 73.50, flange-type output .

  • Application field: Primarily used on ZL30-class 3-ton loaders, serving as the mainstream torque converter model for 3-ton loader drivetrains .

  • Technical evolution: Building on the YJ315-series development, engineers at Shantui's Transmission Division ingeniously designed the YJ315X with gear-forced lubrication, reducing failure rates, securing a market share of over 85% for the YJ315X-series in 3-ton loaders .

Fitment of YJ315X on other loader brands​ (for reference only; does not imply this part fits those models):

  • Junlian JL833 / JL835 loaders: Drivetrain uses the YJ315X torque converter, matched with a single-stage single-phase centripetal-turbine torque converter and a power-shift spur-constant-mesh fixed-shaft transmission .

  • Tai'an Luneng YN935 wheel loader: Drivetrain equipped with the YJ315X torque converter, matched with an F4R2 (four forward, two reverse) power-shift transmission .

  • LN935 Rock King tire loader: Torque converter model YJ315X, single-stage three-element structure, matched with a Yuchai YC6B125-T10 engine and a fixed-shaft power-shift transmission .
