1.Hydraulic Pressure Generation & Transmission
As the core of the gearbox’s hydraulic control system, it converts mechanical force (from the clutch pedal or electronic actuator) into hydraulic pressure. It transmits pressurized hydraulic oil to the clutch slave cylinder or gear shifting valve body, providing power for clutch engagement/disengagement and gear selection.
2.Precise Clutch Control
By adjusting hydraulic pressure according to driver input (e.g., pedal stroke), it precisely controls the clutch’s engagement speed and clamping force. This ensures smooth vehicle start-up, prevents clutch slippage during acceleration, and reduces wear on clutch friction plates.
3.Gear Shifting Assistance
Cooperates with the gearbox’s shift valve assembly: when shifting gears, it supplies targeted hydraulic pressure to the corresponding shift fork cylinder, driving the gear sleeve to engage with the gear wheel. This enables accurate and rapid gear changes, avoiding gear grinding or misalignment.
4.Pressure Relief & Overload Protection
Integrated with a pressure relief valve that automatically releases excess pressure when it exceeds the safe threshold (≥3.0MPa). This prevents damage to the master cylinder, slave cylinder, or hydraulic hoses caused by overpressure, protecting the entire transmission hydraulic system.
5.Status Feedback for Fault Diagnosis
For electronically controlled versions, it is equipped with a pressure sensor that transmits real-time hydraulic pressure data to Chery 019’s Engine Control Unit (ECU). If abnormalities (e.g., pressure drop, no pressure output) occur, the ECU triggers the dashboard warning light and stores fault codes, facilitating timely maintenance.
1.Chery 019 Gearbox Exclusivity & Compatibility
Custom-engineered to match Chery 019’s gearbox structure, the Master Cylinder 019 strictly adheres to original interface dimensions, hydraulic pressure parameters, and mounting standards. It eliminates issues like hydraulic leakage, installation mismatches, or control delays caused by universal master cylinders, ensuring seamless integration with Chery 019’s transmission hydraulic system.
2.Stable Hydraulic Pressure Output
Equipped with a precision-machined piston and valve core (tolerance ≤0.01mm), it maintains consistent hydraulic pressure output (range: 1.2-2.8MPa) even under continuous operation. The integrated pressure-regulating valve prevents pressure fluctuations (≤±3%), ensuring reliable clutch control and smooth gear shifts.
3.Durable & Corrosion-Resistant Construction
The cylinder body is made of high-strength aluminum alloy with anodic oxidation treatment, and the piston uses nitrided steel—both materials resist corrosion from hydraulic oil and wear from long-term reciprocation. The service life is extended by 40% compared to ordinary cast-iron master cylinders, suitable for harsh working environments (e.g., high temperature, vibration).
4.Low Maintenance & Cost-Effective
With a simplified, robust design, it reduces the risk of component failure (e.g., piston seizing, valve blockage). As a Chery 019-specific replacement part, it avoids the high cost of full gearbox overhauls, offering a cost-efficient solution for transmission hydraulic system maintenance.
5.Rigorous Quality Validation
Each unit undergoes strict testing: 10,000+ cycles of reciprocating durability tests, high-pressure leakage tests (3.5MPa static pressure for 30 minutes), and temperature resistance tests (-40°C to 120°C). All indicators meet Chery’s original equipment (OE) standards, guaranteeing stable performance.
