18 - QR019CHB CVT
GENERAL INFORMATION
QR019CHB CVT
Description
Continuous Variable Transmission (CVT) is a kind of continuous mechanical transmission. The most
difference between CVT and common gear-type transmission is that CVT uses two groups of pulleys for
driving instead of complex and heavy gear combined drive. It shifts speeds by changing the contact radius of
drive pulley and driven pulley.
CVT mainly consists of the following components:
 Torque converter
 Planetary gear system
 Drive and driven pulley system (transmission system)
 Steel belt (steel belt consists of two groups of metal rings and hundreds of metal plates)
 Oil pump
 Valve body
QR019CHB CVT features with:
 Automatic and manual modes.
 Electronic hydraulic control.
 At D gear, it realizes automatic continuous variable speeds; at M gear, it realizes manual 7-gear variable
speeds, providing users with dual driving fun.
 It can keep engine lowest speed at a certain vehicle speed.
 It can reduce vehicle emission and NVH (Noise, Vibration, Harshness).
 It can improve vehicle economy and reduce fuel consumption.
 Accelerator pedal responses rapidly when accelerating. Acceleration is gentle and smooth without impact.
