The secondary clutch is mounted to your enter shaft from the transmission, transaxle, or maybe the like. In modern-day CVT methods for instance those used in leisure vehicles, the secondary clutch has two functions: as being a “slave” to the first clutch and to supply a torque sensing ingredient.
Some CVT models even insert a “shift” feeling for those who speed up aggressively. The theory staying that motorists may well need to sense the aged-faculty shifting feeling.
That also clarifies why CVT-Geared up cars have a familiar large-revving character, for the reason that engine revs aren't connected with wheel pace.

As opposed to traditional CVTs, Daihatsu’s D-CVT doesn’t just rely upon belt drive, but introduces break up gears into your mix. As you may see from the cutaway in the D-CVT, you will discover supplemental gears and a planetary gear set fitted for the enter and output shafts with the pulleys, which has a clutch pack to have interaction or disengage the latter. In usual Procedure, when you’re pulling off from a cease and travelling approximately very low to medium speeds, the D-CVT functions like almost every other CVT, Along with the motor’s torque going through a torque converter and into the enter pulley, in advance of staying transferred towards the output pulley through a belt also to the wheels.
