A gearbox unit, for a hybrid vehicle, includes integral electric engine components 1-7 which are used for operating gear changes and for recovering electric energy from and applying electric energy to a gear train. The gearbox comprises planetary gear sets 8, 9, 10 which are engaged by electronic lockers 13 controlled by electro magnetic energy. The lockers 13 engage slots in a casing (16, fig 2) or slots in a static support tube 18 which is an extension of the casing (16). Gear changes between the gear sets 8, 9, 10 is achieved by unlocking an engaged gear outer component from the casing (16), accelerating the outer component using electro magnetic energy to bring the gear set to a common rotational speed and locking another gear set. Also claimed is electro magnetic operation of the gear set, a method of torque application, a gearbox without any relative gear movement in gear sets, a hybrid gearbox unit and a racing car gearbox for a kinetic energy recovery system (KERS). |
