, transmisi D-CVT ini masih dapat dihasilkan dalam pakej yang cukup kecil. Jarak antara titik tengah pulley output dan enter pada transmisi ini hanyalah 136 mm, manakala jarak antara poin enter dan output kotak equipment ini hanyalah 168 mm – menurut Daihatsu, kedua-dua angka ini adalah paling kecil di dunia. Kotak equipment CVT terkenal kerana sifatnya yang tidak mampu untuk menahan tork yang besar, namun walaupun transmisi D-CVT ini menampilkan saiz yang sangat kecil, Daihatsu mendakwa bahawa ia tidak ada masalah untuk didesak oleh tork berjumlah 150 Nm.
Rasio diameter ini bisa diatur melalui sistem komputer, sehingga dapat menciptakan simulasi pergantian gigi dengan tambahan fitur paddle change.

It’s further compact, incorporates a wider differ of ratios and permits for reduce rpms at cruising speeds, with diminished belt friction/slip losses. Perodua claims a category-foremost gas consumption identify of eighteen.9 km for every litre.
Curiously, the Rocky and Raize Have a very Strength button over the steering wheel, which remaps the motor and gearbox for more quickly throttle response. It’s unclear, Even so, In the event the Perodua design will contain the similar work.
It doesn’t simulate any gear modifications like confident more recent CVTs from Toyota and Nissan. Now that is one thing prospects must get accustomed to, particularly in the event that they’re coming from a typical torque converter automated like Perodua’s particular 4AT.
Nonetheless, there are many downsides, as CVTs normally know-how power losses as a result of friction (from the belt or chain) as in comparison with geared transmission.
Unlike regular CVTs, Daihatsu’s D-CVT doesn’t just depend on belt push, but introduces break up gears artikel menarik in to the combine. As you could see from your cutaway with the D-CVT, you will find added gears in addition to a planetary equipment established equipped to the enter and output shafts of the pulleys, having a clutch pack to engage or disengage the latter. In regular operation, whenever you’re pulling off from a stop and travelling up to small to medium speeds, the D-CVT capabilities like almost every other CVT, Along with the engine’s torque under-going a torque converter and in the input pulley, right before remaining transferred into the output pulley through a belt also to the wheels.

This can be a superb set of traits for Daihatsu, mainly because it permits for better packaging in its kei and compact automobiles.
It’s all details and figures at this level, as Daihatsu suggests the Slash up gears help the equipment ratio fluctuate in the D-CVT being prolonged on Each and every higher and low sides from five.
The company notes that a regular CVT’s equipment ratio fluctuate is generally equivalent to that of a standard six-velocity automated, on the other hand the D-CVT in Reduce up method is nearer to an 8-velocity unit in its place.
Walau dari sisi penggunaannya sama saja dengan transmisi matik lainnya, tapi sistem kerja antara CVT dan D-CVT bisa dibilang berbeda.
Ia turut menawarkan pilihan gear handbook 7 kelajuan yang dihasilkan secara maya. Anda boleh mengawal sendiri gear tersebut dengan menggunakan slot M
