I have a setup where I have a step motor which I am attaching a gear onto. The motor will make the gear stand horizontal in a small vehicle. Is there any good gear combinations of LEGO gears that can transform the horizontal torque of the gear into vertical torque that drives the wheels of the small car I am building?

Are there multiple combinations of LEGO gears that can provide this kind of torque transmission?

you may want to omit the "gluing" part - it may have people flee in disgust and it's not really relevant to the question anyway –  Joubarc Jun 29 '13 at 8:33
@Joubarc Thanks for the comment, i am doing it since regular stepper motors powered by an arduino needs to have a "starting" lego brick attached to their rod that spins –  Haaakon Jun 29 '13 at 8:35
That said, this question is very similar, if not a full duplicate, of Strongest gear configuration –  Joubarc Jun 29 '13 at 8:43

There are a number of ways to do this. This is one of the easiest and earliest methods:

gear box

For that design, you'll need this part (3650):

crown gear

You can also do something similar using a combination of bevel gears or double bevel gears:

bevel gear double bevel gear
