Model Number:
QR019CHB
Design & Function:
Pulley-Based CVT with electro-hydraulic control for seamless ratio adjustment (5.0:1 range).
Chain-Driven (Bosch-supplied pushbelt, 12mm pitch) for reduced slip vs. belt designs.
Key Specs:
Torque Capacity: 190Nm (optimized for 1.5L/1.6L NA/T engines).
Fluid: Proprietary CVT-2 oil (viscosity 6.5 cSt @100°C).
Control Module: Integrated TCU with adaptive shift logic.
Durability Features:
Hardened conical pulleys (55 HRC, 0.1µm surface finish).
Auxiliary cooling circuit (max fluid temp 130°C).
Failure Modes:
Belt slippage (fluid degradation or pressure loss).
Valve body wear (clogged solenoids causing "shift shock").
Input shaft bearing noise (improper preload).
Note: Requires 60k km fluid intervals; post-2021 units have upgraded pressure sensors.
