ARRANGEMENT FOR ROTATIONAL DECOUPLING OF ENGINE AND TRANSMISSION

The invention relates to a vehicle powertrain comprising an internal combustion engine (101; 201; 301; 401), a transmission (102; 202; 302; 402) driving at least two wheels, and an intermediate unit (104; 204; 304; 404) connecting the engine (101; 201; 301; 401) and a housing (103; 203; 303; 403) enclosing the transmission (102; 202; 302; 402). The intermediate unit (104; 204; 304; 404) is arranged to allow relative rotation between the engine (101; 201; 301; 401) and the transmission housing (103; 203; 303; 403) about an axis (X) that is colinear with an engine (101; 201; 301; 401) output shaft (117; 217; 317; 417) and a transmission input shaft (118; 218; 318; 418). The arrangement prevents engine vibrations from being transmitted to the transmission, and prevents torque shock from the vehicle wheels from being transmitted to the engine.
