Welcome to component three of our deep dive sequence in the Perodua Ativa (also known as the D55L), exactly where the focus this time is about the transmission that may be utilized by the compact B-phase SUV.
’ and effective transfer of motor power into the output shaft with diminished frictional losses, leading to reduced noise levels and improved gasoline economic system.
Both transmission types give you a handbook change option through steering-mounted paddles or adhere shifters in sport trims.
With none gears, the stepless transmission allows for smoother acceleration and performance, while becoming smaller sized in dimensions when compared with transmissions that do have gears. This is the good list of properties for Daihatsu, mainly because it permits superior packaging in its kei and compact vehicles.
DCTs with tightly spaced gear ratios permit being in best torque band when tuning for higher effectiveness.
It’s much more compact, has a broader selection of ratios and permits reduced rpms at cruising speeds, with lessened belt friction/slip losses. Perodua statements a category-top gasoline consumption figure of eighteen.nine km per litre. On the other hand, as you will notice within the movie above, it even now behaves like a traditional CVT on entire throttle situations, the place it retains on to an extremely substantial rev (among five,500 to 6,000 rpm) beneath tough acceleration. It does not simulate any gear modifications like selected newer CVTs from Toyota and Nissan. Now this is one area people must get used to, particularly when they’re coming from a normal torque converter automated like Perodua’s very own 4AT. Interestingly, the Rocky and Raize have a Power button within the steering wheel, which remaps the motor and gearbox for more rapidly throttle reaction. It’s unclear, nevertheless, Should the Perodua Edition will include the identical functionality. CVT is how forward for Perodua
Welcome to fifty percent a few of our deep dive sequence into the Perodua Ativa (normally referred to as the D55L), the place the main aim this time is to the transmission that might be used from the compact B-section SUV.
DCTs verify considerably speedier on course eventualities even though also getting sila ke pautan ini far more exciting to push aggressively, due to their swift-hearth twin clutch gear modifications.
Based upon all the data We've got up to now, it’s known which the Ativa may have quite a bit in common Together with the Daihatsu Rocky and Toyota Raize. This involves the usage of the 1KR-VET 1.0 litre turbocharged three-cylinder petrol engine and also the Daihatsu New International Architecture (DNGA), the former of which can be paired having a D-CVT. We’ve by now discussed the 1KR-VET and DNGA in sections one and two, so if you'd like to know more details on either of these, just click the one-way links over.
The Raize, which shares the similar transmission, was publicised since the the extremely initial Toyota model to use D-CVT skills in 2019.
five. Satu lagi CVT dipilih ialah kerana ia memiliki saiz yang kompak, ringan dan boleh memenuhi keperluan penjimatan petrol yang ingin dicapai oleh jurutera. D-CVT pula memeliki persamaan prestasi menyamai transmisi automatik 8 kelajuan dalam saiz yang kompak dan ringan.
Bacaan RPM enjin menurun sebanyak 550RPM bagi halaju 100km/j jika dibandingkan dengan transmisi CVT biasa. Maka tak hairanlah Perodua Ativa mencatatkan bacaan eighteen.9km bagi setiap liter
Yusuf on Feb 24, 2021 at three:37 pm Assalamualaikum Hafriz, is this D-CVT using torque converter or damp clutch to take care of the vehicle start from standstill? If soaked clutch, I do think A lot of people will not likely get use to it, the jerk ahead sense will almost always be there identical to punch cvt specially when the clutch adaptation wasn't optimized.
A dual-clutch transmission (DCT) is a complicated automatic mechanical transmission that makes use of two separate clutches for odd and perhaps gears stacked within 1 housing. This gearbox effectively combines the performance and control of a manual gearbox While using the usefulness of the automatic transmission.
