i have a trouble-the topic, i hope who one can help me out.
thank you!

who can help me , thanks a lot.

have a look at the examples and docs.

maybe you want something like:

node->setRotation (core::vector3df(angle, 0, 0) );

Failed how? It crashed your program? The wheel didn't rotate at all? It rotated in an unexpected way?

It is the correct method, assuming that you have a wheel that's in its own node, and that its axis of rotation is through the X axis. If it's not, you'll have to tell us more about your problem.
