Welcome to portion three of our deep dive sequence into your Perodua Ativa (also known as the D55L), exactly where the main target this time is about the transmission that will be used by the compact B-section SUV.
The eCVT technique incorporates an interior combustion motor, two electric powered motors/turbines, and an easy planetary gearset called the “Ability Split Product.”
This may be a good set of traits for Daihatsu, because it permits for increased packaging in its kei and compact cars.
Beneath regular situations, the D-CVT works like an ordinary CVT. It transpires when accelerating from the end and at small to medium speeds. Engine electrical power goes by way of a torque converter into the enter pulley. It’s then transferred to the output pulley by way of a belt. Then ultimately to the wheels.
It’s all points and figures at this stage, as Daihatsu claims the break up gears enable the equipment ratio range of the D-CVT for being prolonged on each minimal and significant sides from 5.3 to seven.three. Over the small facet, it's a better variety of short ratios to take care of acceleration, though on the opposite conclude, large ratios enable it to become improved suited to substantial-speed cruising.
With all this data, it is obvious that D-CVT is how ahead for Daihatsu and Perodua. It’s a brand-new transmission technologies designed together with the DNGA platform, and it will be Utilized in most, if not all new product launches Any more. So, like it or not, D-CVT is listed here to remain.
When you’ll manage to see through the cutaway in the D-CVT, there are actually additional gears along with a planetary equipment set equipped to the enter and output shafts of your pulleys, by using a clutch pack to interact or disengage sila klik link ini the latter.

You’ll manage to see this transition involving normal and Minimize up manner inside a online video by Japan’s World wide web Cartop
While it’s not likely that the current Perodua fashions will change from 4AT to D-CVT anytime speedily, the subsequent generations fashions will really doubtless purpose the new transmission, beginning With all the rumoured DNGA-dependent new D27A Alza.
Device yang dipasang pada Perodua Ativa ialah 150Nm dan jangan risau kerana enjin Ativa hanya menghasilkan tork maksima 140Nm tork. Jadi jangan nak memandai modify turbo, kalau lebih 150Nm tork……….
As being the engine rotates, the sheaves change the diameter of the two pulleys. When one pulley boosts in size, the opposite decreases, which steady transform produces a clean variation in equipment ratios. This allows for an infinite choice of equipment ratios.
That’s not all, as CVTs provide with them a normal whining audio due to all of that belt-on-pulley motion, that is additional profound when it's got to deal with weighty hundreds like throughout challenging acceleration or superior speeds.
