DHT150 Hybrid Transmission
Punch Powertrain’s DHT150, featuring advanced controls and energy management, ensures smooth power shifts, high efficiency, and up to 35% fuel savings. The DHT150 has a dual motor P1/P3 architecture and is designed to operate in combination with sub-2L gasoline engines. Its compact design, with an axial length of 342mm, makes it well-suited for compact A-class vehicles.
Compact design with a 5-axis architecture and fewer shafts, resulting in a smaller transmission. The e-motors with an innovative design using oil cooling rings offer a simple and compact structure.
The low-cost design includes self-developed components such as an inverter, electronic oil pump, and parking mechanism. It uses an electromagnetic clutch that couples power without the need of a complex hydraulic system.
The high-efficiency design includes a full active lubrication system that reduces the amount of lubricating oil needed. The electromagnetic coupling mechanism replaces the wet hydraulic clutch, further improving overall efficiency by 1%.
What makes the DHT150 different:
Compact design
- 5 axis architecture, fewer shafts and compact design result in a class-leading axial length of just 342 mm.
- Oil cooling of motor and oil ring design, simple structure and compact product result in total weight of 110 kg (including oil).
Cost effective
- Self-developed inverter, E-pump, and E-parking systems significantly reduce assembly costs.
- Use of electromagnetic clutch, as opposed to complex hydraulic system for coupling power, provides a competitive advantage in assembly costs.
High efficiency
- Active lubrication design, resulting in a 1-liter reduction in the lubricating oil requirement.
- The electromagnetic coupling mechanism replaces the wet hydraulic clutch, without hydraulic slip and drag loss, improving overall efficiency by 1%.
