On this post, we’re talking about the Ativa’s D-CVT, which isn’t entirely the primary for any Perodua mannequin, even so is completely unique from a conventional CVT. Exactly what does the “D” stand for? How can it function? Learn on to hunt out out.
Earlier than getting into into what Daihatsu is on about, let’s begin with the basic principles. In a typical CVT, there may be an enter pulley that’s related to the engine crankshaft through a torque converter (or clutch pack) and an output pulley that sends energy into the wheels.
It’s all details and figures at this point, as Daihatsu states the split gears enable the equipment ratio selection of the D-CVT to generally be prolonged on equally reduced and substantial sides from five.3 to 7.3. Around the small facet, it's got an increased amount of small ratios to manage acceleration, even though on another finish, substantial ratios let it for being better fitted to high-velocity cruising.
A person system to broaden the equipment ratio selection of a CVT is by expanding the size with the pulleys, Even though This really is counterintuitive If your device has to be little.
Sementara untuk D-CVT, tak hanya menggunakan sabuk baja saja, tapi juga ikut dikombinasikan dengan planetary gea

Based on all the data We now have so far, it’s recognised which the Ativa will likely have a great deal in frequent with the Daihatsu Rocky and Toyota Raize. This involves the usage of the 1KR-VET one.0 litre turbocharged a few-cylinder petrol motor and also the Daihatsu New World wide Architecture (DNGA), the previous of that is paired using a D-CVT. We’ve previously discussed the 1KR-VET and DNGA in areas a person and two, so if you wish to know more about both of them, just click the inbound links earlier mentioned.
At enough time, the business claimed the D-CVT was the world’s 1st break up-equipment CVT system that combines belt generate that has a gear generate, resulting in improved fuel efficiency, acceleration sense and quietness.

Welcome to element three of our deep dive series into the Perodua Ativa (also referred to as the D55L), exactly where the focus this time is over the transmission that could be utilized by the compact B-segment SUV. UPDATE: We’ve pushed The brand new Perodua Ativa! Read through our 1st impressions overview in this article.
The launch gear is used when location off from the end, prior to the transmission switches to belt push just like a CVT as an alternative. This was made to offer a extra direct travel link at low speeds.
The business notes that a standard CVT’s equipment ratio array is often such as that of a traditional 6-pace automated, even so the D-CVT in split mode is nearer to an 8-pace unit instead. This really is achieved purely due to the split gears, as there’s no require to make pulleys larger to get a broader gear array ratio.
