FAQs

Quick answers to practical engineering questions about transmission oil pump development, hydraulic stability, NVH, pressure pulsation, and integration into AT, DCT, and CVT systems.

Typical drivers include pressure instability, excessive pulsation, NVH issues, packaging limits, higher cooling demand, efficiency targets, or the need to adapt an existing pump concept to a new AT, DCT, or CVT architecture.

Yes. The development process is consistent, but the hydraulic targets differ. AT systems often focus on reliable pressure and lubrication, DCT systems on rapid pressure build-up and clutch cooling, and CVT systems on stable high-pressure supply.

Ideally before the pump envelope and hydraulic interfaces are fully frozen. Early involvement makes it easier to optimize suction conditions, gear set design, pressure behavior, packaging, and NVH before costly layout constraints are fixed.

Useful inputs include pressure and flow targets, speed range, oil temperature range, transmission type, circuit layout, suction conditions, packaging envelope, drive interface, NVH limits, and known pulsation or pressure-control issues.

Often, yes. TPV can evaluate the available space, gear geometry, leakage gaps, suction path, and pressure behavior to identify improvement potential within the existing housing or interface constraints.

Prototype systems can be tested for flow delivery, pressure stability, pulsation, NVH behavior, leakage, power consumption, and relief valve behavior before the concept is prepared for series production with partner manufacturers.
