PRODUCT FUNCTIONS

1. Turbo-Adapted Power Transmission

As the core drivetrain component for 1.5T/1.6T compact models, the assembly transfers power from the turbocharged engine to the drive wheels via a high-efficiency dual-clutch system. Unlike traditional torque converters, the dual-clutch design provides direct mechanical power transfer, reducing power loss by 5-7% compared to automatic transmissions. The reinforced gear sets adjust torque and speed dynamically, matching the engine’s turbocharged power output for quick launches and responsive acceleration.

2. Multi-Mode Automatic Gear Shifting

Working in synergy with the vehicle’s TCU, the assembly enables fully automatic gear changes with four selectable modes, adapting to diverse driving scenarios:

Eco Mode: Prioritizes fuel efficiency by upshifting at 1,700-2,200 RPM and optimizing clutch engagement pressure to reduce friction.

Normal Mode: Balances power and efficiency, shifting at 2,300-2,800 RPM for smooth daily driving in urban and suburban areas.

Sport Mode: Delays upshifts to 3,500-4,200 RPM, enhances throttle response, and shortens shift times by 20% for aggressive acceleration.

Snow Mode: Adjusts shift points to start in 2nd gear and reduces torque delivery to prevent wheel spin on slippery surfaces.

The TCU also learns driver habits (e.g., frequent acceleration/deceleration) over 30-50 kilometers, automatically adjusting shift logic for personalized driving.

3. High-Efficiency Dual-Clutch Operation

The dual-clutch system (dry-type for weight optimization) features two independent clutches: one for odd gears (1st, 3rd, 5th, 7th) and one for even gears (2nd, 4th, 6th). This design allows pre-selection of the next gear, enabling near-instant shifts (≤150ms) without power interruption. For turbocharged engines, this eliminates the “power gap” common in traditional automatics during gear changes, ensuring continuous power delivery during acceleration. The clutch system also includes a temperature sensor that monitors heat buildup, adjusting engagement pressure to prevent overheating.

4. Precision Hydraulic & Electronic Control

The electronically controlled valve body serves as the assembly’s control center, directing hydraulic pressure to the dual clutches and shift solenoids via precision-machined passages. A digital pressure regulator maintains hydraulic pressure within 0.8-2.8 bar with ±0.04 bar accuracy, ensuring consistent clutch engagement and smooth gear shifts even under varying turbo boost loads. An 8μm fine filter traps micro-metallic debris from turbo operation, protecting the clutch and solenoid components from contamination.

5. Advanced TCU Communication & Diagnostics

The assembly establishes two-way communication with the TCU via the 14-pin connector, transmitting real-time data including clutch temperature (±2°C accuracy), gear position, solenoid status, turbo boost pressure, and fluid quality. If a fault is detected (e.g., clutch slippage, solenoid malfunction), the TCU stores a specific DTC (e.g., P0900 for clutch actuator circuit malfunction) and triggers a multi-level warning (dashboard light + audio alert + central control message). Mechanics can use diagnostic tools to perform advanced functions like clutch adaptation and transmission reset, ensuring optimal performance after maintenance.

6. Comprehensive Safety Protection

Park (P) Position: Features a hardened parking pawl (HRC 58) with a spring-loaded locking mechanism, securely locking the output shaft to prevent vehicle rollaway even under high torque.

Reverse (R) Interlock: Requires the brake pedal to be depressed and vehicle speed ≤3 km/h before allowing reverse engagement, preventing accidental shifts.

Limp-Home Mode: If a critical fault is detected (e.g., clutch overheating), the TCU limits the assembly to 3rd gear and reduces engine power by 30%, allowing the driver to safely reach a repair facility.

Overheat Protection: Activates when clutch temperature exceeds 220°C, reducing torque delivery and triggering a warning to prevent clutch damage.

Collision Safety: Integrates with the vehicle’s airbag system, automatically shifting to neutral and engaging the parking pawl during a collision to prevent secondary accidents.

The Transmission Assembly Gearbox F01-1500010AB is exclusively engineered for compact and subcompact vehicles from domestic mainstream brands, with dedicated compatibility for models such as Changan UNI-T (2021-2024), Geely Coolray (1.5T), and Chery Arrizo 8 GT (1.6T). Adhering strictly to the OE design standards of these target models, it matches critical parameters with ultra-high precision: bell housing flange dimensions customized for 1.5T/1.6T turbo engine interfaces, 20-spline input shaft (enhanced wear resistance), 24-spline output shaft, and mounting point positions with a tolerance of ±0.07mm. This dedicated compatibility eliminates on-site modifications, ensuring seamless integration with the vehicle’s powertrain and avoiding issues like TCU (Transmission Control Unit) communication delays, powertrain vibration, or torque mismatch.

2. Lightweight yet Durable Construction for Turbo Dynamics

Gear System: Core gear sets are crafted from 18CrNiMo7-6 alloy steel, processed through vacuum carburizing (depth: 1.0-1.3mm), high-frequency quenching, and precision honing. This treatment achieves a surface hardness of HRC 59-62 and core toughness of ≥90 J/cm², enabling the assembly to withstand continuous torque loads of up to 260 Nm—perfectly matching the power output of 1.5T/1.6T turbo engines. The gear set design is optimized for lightweight, reducing overall assembly weight by 8% compared to generic counterparts.

Housing: Die-cast from ADC12 aluminum alloy with a bionic ribbed structure (inspired by insect exoskeletons) at stress points, the housing resists thermal expansion and vibration (up to 38g) under turbo operating temperatures, maintaining structural integrity in the range of -40°C to 135°C.

Sealing & Protection: Equipped with double-lip Viton rubber seals (with a heat-resistant coating) and stainless steel gaskets, the assembly provides reliable resistance to high-temperature transmission fluid leakage.
