Punch Powertrain Produces Its 100.000th VT5 Transmission
After the huge success of the VT2/VT3 transmission line in China, Punch Powertrain came up with a series of other innovative solutions. One of them was a VT5 transmission that hit the market just over a year ago. Within such a short period of time, the company managed to produce the 100.000th VT5 unit.
Engineered on the basis of the reliable VT3,
the VT5 was designed to be applied on a wider range of cars. It has the torque
capacity of up to 280 Nm and has an impressive ratio coverage for a single
stage CVT (7.2). It comes with a torque converter, which has a positive impact
on the driving experience and incline performance. This gear shifting solution
gained popularity among car manufacturers, especially in the SUV segment.

In addition, this innovative transmission can be complemented with several optional features, such as start-stop and sailing. Moreover, the VT5 can be equipped with a special shift-by-wire system. It is also known for active controlled dual stage pump as well as innovative secondary shaft-assembly.
Key
attributes of this transmission system are the following:
- 28 mm pushbelt, single mode variator
- Increased system pressure, max. 70 bar
- Independent pulley pressure control
- Reduced drag (cold start & churning loss)
Main elements of the VT5 transmission
This CVT solution is currently supplied to Punch Powertrain customers in China, namely clients Ford-JMC and DFSK. If during the 1-st year of production the main objective was to ensure its high level of quality, the VT5 unit now enters the next phase of its life cycle: introduction of possible modifications and cost optimization. Moreover, the engineering team of Punch Powertrain is currently preparing the release of new product variants, to meet the needs in the rapidly-changing auto market.
