Bunyi Geseran: Geseran yang luar biasa dalam gearbox boleh menyebabkan bunyi yang tidak diingini, biasanya disebabkan oleh komponen dalam yang haus.

Kebocoran Minyak Gearbox: Ini adalah masalah biasa yang boleh menyebabkan kekurangan minyak pelincir dan akhirnya menyebabkan kerosakan pada gearbox.

For 2022, Proton has focused on the CVT’s program, including new capabilities to Enhance the overall performance and refinement on the transmission. The most vital of those is the return with the stepped-ratio SAT function, which dispenses Along with the focused button and is also now activated quickly once the accelerator is pushed past a certain threshold. As such, the CVT is able to simulate an computerized gearbox’s “kickdown” and keep onto a specific ratio prior to “shifting up”.

PROTON mengambil keputusan untuk terus mengekalkan sistem transmisi jenis CVT pada model Persona dan Iriz (2022) berpaksikan faktor utama seperti hasil tinjauan, kajian dan soal bajet.

The Iriz and Persona past obtained An important components refresh for your CVT in 2019 as part in their 1st facelift, directed at addressing perceived trustworthiness. The revisions incorporated a redesigned oil pump and hydraulic unit, a different oil seal and bearing, an optimised pinion gear to lower sounds and an improved transmission housing (to minimise oil leaks and porosity) and inner element machining. As outlined by Adzrai, these variations have been effective, decreasing the number of guarantee claims significantly. “We can easily see that from your start until eventually these days, We've got experienced an 80% reduction in warranty claims,” he mentioned.

Penambahbaikan pertama ialah ciri SAT yang berfungsi secara automatik (tiada butang) berdasarkan tekanan pada pedal minyak. Ciri itu melancarkan lagi operasi transmisi.

Gearbox 4AT Aisin adalah transmisi automatik four-kelajuan yang digunakan dalam versi Proton Saga yang lebih top quality. Ia terkenal dengan prestasi yang lebih halus dan jangka hayat yang lebih lama berbanding product-design lain.

This before Edition was discovered to generally be a lot less than seamless in apply; in the event the SAT button was pressed, it would simulate stepped ratios and continue being that way right up until the motive force deselects it to return to conventional, stepless CVT operation. Proton experienced uncovered that transmission button modes tend not to be used, and once the simulated AT method in a very stepless CVT is made use of, it often “will not generate too,” famous Adzrai. What Proton has now, then, is really an adaptation with the stepped automated mode that does absent which has a individual button activation, and as a substitute employs throttle input. For throttle posture of involving zero to 60% or 70%, the transmission capabilities Typically as a CVT, outside of which it goes in to the ‘stepped’ manner. This really is to mitigate the “droning” sound when a CVT-Outfitted vehicle is taken to complete throttle, since it selects the ratio to position the motor during the thick of its powerband – about 5,000 rpm to 5,500 rpm – although the rest of the driveline, and for that reason auto velocity, gradually catches clicking here up.
