Welcome to element three of our deep dive sequence in to the Perodua Ativa (often called the D55L), where the main target this time is over the transmission which will be utilized by the compact B-segment SUV.
The eCVT system incorporates an interior combustion motor, two electrical motors/turbines, and an easy planetary gearset known as the “Electricity Break up Gadget.”

Even so, when you are seeking lightning-fast gear shifts and improved acceleration, DCT is usually a more sensible choice when considering the CVT vs DCT debate. In this article’s a more thorough explanation:
Within this write-up, we’re speaking about the Ativa’s D-CVT, which isn't only the first for a Perodua model, but differs from a standard CVT. What does the “D” stand for? How can it run? Keep reading to understand.
For additional figures, the company suggests that the gap among the centre from the enter and output pulleys inside the transmission is only 136 mm, when the distance concerning the centre on the transmission’s enter and output points is just 168 mm, both equally claimed to become the smallest on the globe.
Sementara untuk D-CVT, tak hanya menggunakan sabuk baja saja, tapi juga ikut dikombinasikan dengan planetary gea
Daihatsu’s whole internet marketing phrase for its D-CVT is Twin manner CVT, and the transmission 1st made its debut alongside the DNGA platform While using the fourth-generation Tanto kei MPV back in July 2019. At time, the corporate claimed the D-CVT was the world’s initial split-equipment CVT process that mixes belt generate using a gear drive, resulting in enhanced gasoline effectiveness, acceleration come to feel and quietness. The Raize, which shares precisely the same transmission, was publicised as the the pretty initially Toyota design to make use of D-CVT technologies in 2019. Why a CVT is perfect for tiny cars In advance of stepping into what Daihatsu is on about, let’s start with the fundamentals.
The extremely-brief equipment adjust intervals of the DCT make it possible for for being inside the engine's best electrical power array.
The D-CVT has an additional gear and also a planetary gear set. They're connected to the enter and output shafts from the pulleys. A clutch pack is used to engage or disengage the planetary gear established.
The company notes that a traditional CVT’s gear ratio variety is often akin to that of a normal 6-velocity automatic, although the D-CVT in split method is nearer to an eight-speed device instead.
All through acceleration, when the car or truck requirements a lot more pace but much less torque, the diameter on the secondary pulley decreases as its going sheave moves away from the static sheave.
Because the motor rotates, the sheaves modify the diameter of both pulleys. When just one pulley raises in sizing, another decreases, which continual modify makes a smooth variation in gear ratios. This enables for an tajuk perbincangan infinite number of gear ratios.
Even though well-liked in hybrids owing to electric torque fill, CVTs also go well with normal gasoline-only driven economy segment autos.
