Welcome to component 3 of our deep dive sequence in the Perodua Ativa (also referred to as the D55L), in which the main focus this time is to the transmission that should be employed by the compact B-section SUV.
In distinction to standard CVTs, Daihatsu’s D-CVT doesn’t simply depend on belt drive, nevertheless introduces cut up gears into The mixture.

Having said that, when you are looking for lightning-rapid gear shifts and much better acceleration, DCT can be quite a more sensible choice When it comes to the CVT vs DCT discussion. Right here’s a more in-depth rationalization:
A crawler or minimal-assortment equipment manner optimizes DCTs with the complex necessities like torque modulation envisioned in treacherous off-road circumstances. CVTs absence the Manage required in slippery traction-challenged eventualities.
One technique to grow the gear ratio variety of a CVT is by growing the size from the pulleys, Whilst this is counterintuitive When the unit should be little.
By altering the efficient diameters from the enter and output pulleys infinitely, seamless acceleration is reached over the rpm array without the need of harsh equipment shifts.
DCTs confirm substantially more rapidly heading in the right direction Info penulis eventualities although also currently being much more enjoyable to travel aggressively, as a result of their speedy-hearth twin clutch equipment modifications.
The sophisticated factors and controls needed for DCT gearboxes increase their build prices in excess of normal automatics and CVT gearboxes.
The Raize, which shares the identical transmission, was publicised since the the extremely to start with Toyota mannequin to make use of D-CVT know-how in 2019.
That’s the place the confusion could set in, as that transmission (known as the K120) remains sitting down very at the very best of Toyota’s hierarchy of CVT tech which, supplied its larger cost plus much more ‘high quality’ function established, is reserved for its additional high profile automobiles fitted with its Dynamic Power household of engines in specific variants from the Corolla, Camry, C-HR, and RAV4.
The enter pulley radius decreases as being the engine revs rise even though simultaneously, the output pulley diameter raises proportionally. This retains the belt stress constant in spite of pace changes.
Walau dari sisi penggunaannya sama saja dengan transmisi matik lainnya, tapi sistem kerja antara CVT dan D-CVT bisa dibilang berbeda.
The pulleys are linked by a belt. The main pulley is linked to the motor. The secondary pulley is linked to the drive shaft. Each pulley can develop and agreement at the same time as a result of its transferring sections.
