Duel Clutch Transmission – DT1

Punch Powertrain’s DT1 is well suited for compact vehicles and challenging driving conditions.

It’s a cost-friendly transmission performing well above its compact size and design.

Our Dual Clutch Transmission is specifically designed if you need a compact vehicle segment. It is a highly efficient and compact 7-speed automatic DCT with wet clutches, and  more cost-effective than other full automatic transmissions. But there’s more  – it offers excellent driving comfort, efficiency and an exceptionally wide ratio coverage.

We conceived and patented a new way of realizing the dual clutch principle. One of the two clutches contains an additional planetary gearset to be engaged between the engine and the transmission. This allows the transmission to shift seamlessly between 7 forward ratios, using only 4 gear pairs and one side shaft (similar to MT). This results in a lighter, more compact product, paired with a considerable cost reduction.

Punch Powertrain’s DT1 Dual Clutch Transmission is intended for vehicles with engine torque up to 200Nm and engine power of up to 110 kW. The large first gear ratio (1:18) is optimized for this application, resulting in smooth accelerations in any circumstance and strong capabilities on inclines. The overall wide ratio coverage of up to 8, enables the transmission to operate with a favourable fuel consumption. DT1 represents an advantageous alternative for 4ATs and 5(A)MTs.

What makes our DT1 different:

Compact Design & Light weight​

In this unique design one of the two clutches contains an additional planetary gearset. It can be engaged between the engine and the transmission, allowing the transmission to shift seamlessly between 7 forward ratios, using only 4 gear pairs and only one layshaft. This results in a lighter, more compact product.

Wet Clutch Technology​

Thanks to its wet-clutch technology, the transmission offers consistent performance under all circumstances including inclines and in stop-and-go traffic. The wet clutch improves the thermal management and keeps the transmissions' temperature under control for a seamless experience, even during repeated launches on steep slopes.

Machine Learning

The DT1 is fitted with machine learning software that optimizes the transmission’s behavior. This is done based on its diagnostics and analysis of thousands of parameters at the speed of 100 times per second.

Self-healing​

Another asset is the self-healing technology that prevents the build-up of dust or debris through an automatic vibration system, decreasing the need of your active maintenance.
