ABSTRACT:
A transmission for an electric vehicle that allows forward movement in a first shift stage with hydraulic pressure failure and permits forward and rearward towing. The first shift stage of the transmission T is established by a main first-shift gear 19 which is brought into and out of engagement with a main shaft Sm connected to an electric motor Mm through a towing clutch 50, and by a counter first-shift gear 26 carried on a counter shaft Sc with one-way clutch 47 interposed therebetween. During backward towing of the vehicle, the rotation of a driven wheel is reversely transmitted by way of the counter shaft Sc, the one-way clutch 47, and the counter first-shift gear 26 to the main first-shift gear 19, but by actuating the towing clutch 47 into a disengaged state to disengage the main first-shift gear 19 from the main shaft Sm, the electric motor Mm can be prevented from being forcibly driven and being damaged.
