Multi-speed transmission for vehicle

A multi-speed transmission for a vehicle, the multi-speed transmission comprising:

• an input rotating member;
• an output rotating member;
• a first transmitting portion which has a first intermediate output member which slows and transmits rotation from the input rotating member, and a second intermediate output member which reverses and transmits rotation from the input rotating member;
• a second transmitting portion which includes four rotating elements formed by some sun gears, carriers, and ring gears of two planetary gear sets being connected together, and which transmits rotation to the output rotating member;
• a first clutch element which selectively connects the first intermediate output member and the fourth rotating element together;
• a second clutch element which selectively connects the input rotating member and the second rotating element together;
• a third clutch element which selectively connects the first intermediate output member and the first rotating element together;
• a fourth clutch element which selectively connects the input rotating member and the first rotating element together;
• a fifth clutch element which selectively connects the second intermediate output member and the first rotating element together;
• a first brake element which selectively holds the first rotating element to a non-rotating member;
• a second brake element which selectively holds the second rotating element to the non-rotating member, wherein
• the rotation speeds of the first, second, third and fourth rotating elements have a relationship expressed with straight lines in each speed ratio.
