Welcome to part 3 of our deep dive series into your Perodua Ativa (generally known as the D55L), the place the focus this time is over the transmission that may be employed by the compact B-section SUV.
9. Berdasarkan laporan ujian awal, Perodua Ativa ditawarkan dengan satu butang tambahan “Energy” bagi menala ECU enjin dan transmisi agar menjadi lebih agresif.
It accomplishes this by incorporating a Actual physical initially equipment that might bypass the usual belt and pulley, consequently its identify, which is usually haphazardly abbreviated as 'D-CVT'
Prolonged drives obtain peak drivetrain efficiency and decreased NVH degrees within a DCT via custom made gear established selection for supposed speeds. Adaptive cruise functions also enhance DCTs' seamless automobile shifts between gradients. CVT features are a lot less suited to highway use.
It’s all facts and figures at this time, as Daihatsu says the split gears allow the gear ratio array of the D-CVT to get extended on both of those reduced and large sides from 5.three to 7.3. Within the small facet, it's got a higher quantity of quick ratios to deal with acceleration, whilst on the other end, superior ratios allow for it being better fitted to large-velocity cruising.
It’s further compact, provides a wider differ of ratios and permits for minimize rpms at cruising speeds, with diminished belt friction/slip losses. Perodua statements a class-top fuel intake decide of eighteen.9 km per litre.
Kondisi ini sudah pernah redaksi rasakan sendiri ketika menjajal All New Xenia beberapa waktu lalu. Putara atasnya memang lebih terasa terisi selain dari tiap perpindahan gigi yang terasa clean.
CVT digunakan pada halaju rendah 2. Dalam operasi D-CVT, apabila kereta mulai bergerak kuasa enjin akan dihantar dan digandakan melalui sistem CVT biasa.
Selain itu juga ada posisi M (handbook) yang memungkinkan pengendara merasakan sensasi memindahkan gigi Info penulis secara handbook.
At the time, the business claimed the D-CVT was the whole world’s very first split-equipment CVT procedure that mixes belt drive using a gear generate, leading to improved gas effectiveness, acceleration come to feel and quietness.
The system has two major elements: a driving pulley as well as a pushed pulley, linked by a belt to transfer movement. On the other hand, it struggles to deal with substantial torque in vehicles.
The input pulley radius decreases since the motor revs rise though simultaneously, the output pulley diameter improves proportionally. This keeps the belt pressure continuous no matter speed adjustments.
Daihatsu also promises that drivers will have fifteen% much better acceleration experience, which really should reduce the “sluggishness” that folks feel when employing normal CVTs.
For further figures, the company suggests which the hole in between the centre in the enter and output pulleys in the transmission is actually 136 mm, While the hole amongst the centre with the transmission’s enter and output components is solely 168 mm, Each individual claimed to generally be the smallest over the earth.
