Automatic Transmission Trends and System Solution Double Clutch Transmission

DCT

Double Clutch

Transmission

› DCT use two clutches, each clutch operate independently

› One clutch controls the odd gears (1st, 3rd, 5th and reverse), while the other controls the even

gears (2nd, 4th and 6th)

› Using this arrangement, gears can be changed without interrupting the power flow from the

engine to the transmission

› Sophisticated electronics and hydraulics control the clutches and gear like in conventional

automatic transmissions

Automatic Transmission Trends and System Solution Continuous Variable Transmission

CVT

Continuous

Variable

Transmission Drive Pulley

Driven Pulley

› CVT use a belt that runs between two variable-diameter pulleys to give a wide range of ratios

and a smooth transition between them.

› The advantage of a CVT is that the engine can be kept at its most efficient speed while the

transmission adjusts to changes in load or road speed.

› A limitation is that CVT rely on friction between the belt and the pulleys, CVT couldn’t yet

handle a lot of power

Automatic Transmission Trends and System Solution Step-Automatic Transmission

AT

Step-Automatic

Transmission

› AT use a torque converter to transfer power from the engine to the transmission

› AT contains several gear sets, and the different “speeds” are chosen by engaging

electronically controlled, hydraulic clutch packs

› AT tend to be very smooth in operation, but lose some efficiency (and thus fuel economy) due

to the slight “slip” of the fluid torque converter and driving the hydraulic pump to operates the

clutch packs

AMT

Automated Manual

Transmission

› AMT is the automation of the conventional manual transmission system

› There is no big change in terms of design, basic principles in AMT as compared to manual

transmission

› AMT manages clutch and gearshift operations with hydraulic or electric actuator

› Shift shocks in manual transmissions are not eliminated in AMT

Automatic Transmission Trends and System Solution Dedicated Hybrid Transmission

DHT

Dedicated Hybrid

Transmission

› DHT is the solution for Hybrid Vehicle

› DHT use at least two sources of propulsion: an ICE, and at least one e-machine. Without

either of these sources, they are not fully functional

› DHT can offer several modes, for example serial, parallel, power-split CVT mode, all electric

and ICE mode
