Hi guys,

Hopefully this is straight forward:

In the following pic....

...we can see that reverse gear has the same everything almost as first gear (which produces the most torque)..... so why is the ratio like -2:1 thus giving the impression the torque is not existant in reverse?

help lol 

Cheers

At a guess, its because the torque is in the "opposite" direction .. positive torque gives a forwards motion, negative torque gives a rearwards (reverse) motion ??

Gearbox output torque in reverse is the reverse of the input torque hence it creates a negative torque with respect to the input

Fair enough, Nige. I just assumed the torque would be calculated irrespective of direction.

Thanks Mark. is there then a torque measurement not in comparison of the input shaft? (if that makes sense)
